Notes on GRAPTAS C AUREUM and INTERROGATIONIS.-Fab.

By WM. II. EDWARDS.

Until the publication of Mr. Lintner's paper in Trans. Amer. Ent.
Soc, 18G!3, these two species had been treated by late authors as
identical, some describing one and some the other, or sexes of
either, under the names C-aureum and Interrogationis indififcrently.
Our collectors had accepted without much question, the statement of
Boisduval and Leconte, which is in effect, that although there would
seem to be more than one species, yet as the caterpillars are the same,
the butterflies must be the same also.

The first mention of a Papilio G-aurcum is in Linnaeus, Syst. Nat,
1760, I, p. 477, as follows; "C-aureum. P. N. alis angulatis fulvis ni-
gro maculatis; posticis subtus C-aureo notatis. Habitat in Asia."

This species is now recognized as equivalent to Angelica, Cramer,
pi. 388, an Asiatic species found in India and Japan, materially and
unmistakably differing from any American Grapta. Though, be it
noted that the above indefinite description applies to either of our
large species, or indeed, excepting the silver mark, to any Grapta then
or now known.

In 1775, Fabricius, Syst. Ent. page 500, describes C-aureum nearly
in same words; viz, "P. alis dentato-caudatis, fulvis, nigro-maculatis;
posticis subtus C-aureo notatis. Habitat in Asia.'' and refers to Linnaeus.

In 1781, Fabricius, Sp. Ins. 11, p. 94, again describes G-aureum in
same words, with same reference to Linnaeus and habitat, but refers
also to Cramer, 11, pi. 19, fig. E, F. Cramers figures purport to repre-
sent an American species, which may properly be considered as the one
had in view by Fabricius, althoiigli tliere was error in his reference to
Linnaeus and in his habitat, caused naturally by the vague description
of Linnaeus.

TRANS. AMER. EST. SOC. (1) JANUARV, 1870.

2 WM. H. EDWARDS.

In 1797, Abbot (Insects Georgia), figured without description as
C-aureum the species before given by Cramer.

Mr. Lintner determines that both Cramer's and Abbot's figures rep-
resent the male of that one of these two species which has a red upper
surface and much falcated forewings, in contradistinction to that with
black hind wings, and slightly or not at all falcated forewings, which
he calls Umbrosa. To avoid confusion, I will, for the present, speak
of these as C-aureum (Fab.) and Umhrosa.

At first glance Abbot's figures seem to represent Umhrosa. But
after careful comparisons with many individuals of both species, I think
Mr. Lintner's conclusions correct. There is a great variation. Some
Interrofjationh have very dark brown hind wings, and may well have
stood for Abbot's figures, which are coarsely executed. The outlines
of both wings and falcation of fore wings, as Mr. Lintner points out,
are those of C-aiirenm, not Umhrosa. On the under side the coloring
is faithful to neither but nearest C-aureum. The same remarks will
apply to Cramer, whose figures, also, are very coarse. In fact, nothing
would be lost by rejecting all these figures.

In 1798, Fabricius (Supp't. p. 421), for the first time mentions and
describes P. Iiiferrogatlonis, viz; "alis caudatis fulvis nigro maculatis,
suhtus (jhi\icis: striga punctorum nigrorum, posticis C-aureo notatis.

Habitat in America boreali.

Nimis afiinis P. C-aureo at pauUo major et alae suhtus glaucse striga
punctorum n igrorum.^'

Wings tailed, fulvous, spotted with black, beneath glaucous (i. e. a blue or green
inclining to grey or white) with a transverse band {striga) of black points.* ••■■ * *
Extremely like P. C-aureum but a little larger and the wings beneath glaucous
with a transverse band of black points.

Now Fabricius could not have said that his Interrogationis was "ex-
tremely like" Angelica Cramer, (that is, C-aureum, Linnaeus,) for as
stated, the two difi"er materially and unmistakably.

But the words gJaucse, striga punctorum nlgrorum, twice repeated,
mark the importance attached to those characters. They were in fact
the characters relied on as at once determining the new species from his
C-aureum, thereby also determining this C-aureum itself, and with the
words jMiuUo major apply completely to the female of Umhrosa. This
alone of the males and females of the two species can be called glau-
cous, that word well expressing the color by which the wings are suf-
fused. To either sex of C-aureum the worxl is wholly inapplicable,
the male bein"; brown in varied shades and the female brown sufi'used

AMERICAN LEPIDOPTERA. 3

with ochraccous. And Umbrosa, of the two species, is the one distin-
guished in both sexes by a band of distinct black points crossiiig both
icings. There are traces of such a band in the male C-aureum, (as
there are in all Graptas) but the points are less conspicuous always and
usually in part obsolete. In the female the traces are still fainter and
the points almost always obsolete.

In the description of Umbrosa, by Mr. Lintner, these black spots are
spoken of as pupils of rounded spots of lighter brown. I regard the
"rounded spots" as no spots, but as the faintest halo about the black spots.
Mr. Lintner speaks of these black pupils as distinct on the fore-wings
in the male and fcma/c, exprcj^sly saying also that "in the female the
rounded spots are obsolete^ but the jyuj)ils are distinct," (the striya punc-
torum nigrorum^ ; and that in the female of the other species (^C-au-
reiini) '•'■these pupilhited spots do not appear." ,

I conclude therefore, that Umbrosa, female, Lintner, is neither more
nor less than the true Interrogation is, Fabricius, and that the former
name can rank only as a synonym. For aught that appears the male
was unknown to Fabricius.

In tliis conclusion I am sustained by Godart, so far as to the fact of
the female of the one or the other of these species being the Interroga-
tionis, Fab. In Encyc. Method., IX, p. 302, 1819, he says: "Fabri-
cius has taken the male for C-nitrenm of Linnaeus and has made of
the female a separate species under the name o^ Interrogationis. And
he gives as synonyms C-aureum Fab. male, C-aureum Cramer, and In-
terrogationis Fab. female. Then as the name C-aureum was preoc-
cupied by Linufeus, and regarding all these forms as varieties of one
species, he applies to them the name Interrogationis, Fab., and says,
describing it, " Le dessous de male est d'un gris bois onde et varie
de brun ;" (i. e., C-aureum, Fab. but by no means the true male of In-
terrogationis Fab.) le dessous de la femelle est brun et l^g^rement
glac($ de vert blanchatre, surtout aux secondes ailes :" ( 9 Interrogati-
onis Fab.) Thus giving to the male of one species the female of the
other.

On page 819, he further says of his Interrogationis % " Le dessous
est d'un brun noiratre ou feuille-morte plus on moins nuance de gris
violet." This describes a variety of C-Aureum % , which is sometimes
flushed with purplish.

Boisduval and Lecontc give a badly executed figure, composed, appa-
rently of the upper surface of C-aureum and the under surface of
Interrogationis Fab. % . The shape is rather that of the latter. It

4 WM. H. EDWARDS.

is copied from one of Abbot's drawings, a poor copy of a poor origi-
nal; but the under side is not to be mistaken.

The accompanying description mixes the species and sexes surpri-
singly. Closely following Grodart, they say, " Le dessous des ailes est
tantot d'un gris de bois ond^ et vari^ de brun," {% C-aurcum) '' tantot
d'une couleur ferrugineuse ou feuille-morte uniforme, avec I'extremit^
un peu plus claire," ( 9 C-aureum). " Jouvent brun, legeremeut glace
de vert-blanchatre, surtout aux ailes mf^xlenres:" {^ Literroff at ionis,
Fab.) and add that in all the varieties there is a silver spot, sometimes
in form of a G, and sometimes of an uninterrupted C or interrogation
point. Here these authors seem to me to have also included Grnpta
Comma, Harris, then undescribed, as a third species, that species in
many respects resembling the other two, and being distinguished by an
uninterrupted C, a character unknown to me in the others.

Boisduval and Leconte further add, " This Vanessa varies much, and
if we did not obtain from the same caterpillar (la meme chenille) the
varieties of which we have spoken, we could easily make three species ;'
here, again, I suppose, alluding to Comma.

Dr. Harris describes Interrogatlonis. 2nd Ed. Ins. Mass, p. 298, as
having the hind wings in the male most often black above, except at
base, and sometimes of this colour in the other sex also ; under side ot
the wings in some rust red, (^C-aureum) " in others marbled with light
anu dark brown, glossed with reddish white," (S Interrogationis P^ib.)

Dr. Harris therefore considered the mule luferrogationis Fab. as the
type, and the male C-aureum as a variety, and the female C-aureum as
the type, and the black female a variety.

However, in what manner authors subsequent to Fabricius regarded
these species has no direct bearing upon the main question, which is —
did Fabricius properly distinguish them or either of them ? Certainly
he did. He was unacquainted with the male of his Interrogationis,
but his description of the female was precise, and the language used
proves that he had not in mind this male when he referred to C-an-
reuni. His C-aurenm was without a band of black spots, and was
what he considered to be Cramer's C-anreum. That the latter was
intended to represent the male of the other species is the opinion of
Lintner and, I think, with reason.

If Mr. Lintner is right on this point, then, inasmuch as the name
Interrogationis was applied by Fabricius to the female of the black
winged species ( Umbrosa), that is now the true specific name.

AMERICAN LEPIDOPTERA. 5

If he is wrong, and the figures of Cramer and Abbott may be sup-
posed to represent the male of I'mhrosa, then to this male Fabrieius
applied the name C-aureum ; which being pre-occupied, his subsequent
name, Interrogation^, covers both sexes and the species.

]My eonelusioi* is this: in one case, the red winged species is still
unnamed, in the other its name, (C-<nircuni), is pre-occupied. I there-
fore propose to call it Fahrkii, in honor of the great naturalist.
The synonyms of the two species will then be as follows, viz.:

G. Fabricii, described as follows:

Form alike in both sexes ; primaries strongly falcated, much incised ;
secondaries have a prominent tail, anal angle prolonged.

Male; expands 2.5 to 2.7 inches; Upper side bright red fulvous,
the terminal third of primaries and whole of secondaries obscured by
ferruginous ; a common sub-marginal series of small fulvous patches.
Primaries have upon the disk five rounded black spots, disposed in a
right angle, of which the two smallest are in the cell and three trans-
verse to these in the interspaces ; in the upper part of first median in-
terspace usually another spot of fainter color; a large, sub quadrate
spot depending ubliquely from the costa, covering the arc; near apex
two black or blue puints. Secondaries have fulvous patches on costa
and at origin of first and second median nervules; a large, bi-lobed,
black spot on costal margin, a small spot near base of second subcostal
nervule and another at base of second median; hind margin of both
wings and abdominal margin at the fold largely edged witli lilac ;
fringes short, fuscous.

6 WM. n. EDWARDS.

Under side ■wholly clouded or mottled with shades of brown and fer-
ruginous, sometimes partially suffused with purplish ; the basal space
limited by a ferruginous line, the course of which, on primaries, is an-
gular, on secondaries, undulate, turning in at the cell and extending
far down the abdominal margin, broadly bordered withiTi by ferruginous
and cinereous ; enclosed in the basal space a few patches of darker color,
especially on costal margins; on primaries three small spots at base of cell;
outside the ferruginous line a narrow, unclouded space, beyond which,
on primaries, the limb is mottled with ferruginous and ochraceous; a
sub-apical blue-grey patch, inclining to white, on costa; inner angle
tinged with lilac; along the incision a row of metallic blue streaks and
points, continued on the whole margin of secondaries, often nearly ob-
solete; a common submarginal row of five black points, more or less
obsolete, or only distinguishable by a glass, and partially edged by
blue scales; costal edge ferruginous, beaded by rounded yellow spots,
between which and the costal nervure the ground is yellow, irrorated
with ferruginous. Secondaries have a ferruginous, nebulous, suba-
pical patch, and a stripe curving from the upper median nervule
towards anal angle; silver spot an interrupted C; the hind margins of
both wings much covered by fiue, abbreviated, ferruginous streaks.

Body above fulvous covered on thorax with greenish hairs; beneath
grey ferruginous; legs buff; palpi buff, on upper side fulvous; anten-
nae fuscous above, annulated below with buflF; club fulvous tipped with
buff.

Female ex'panda 2.6 to 3 inches. Upper side in color and markings
similar to male. Under side brown, suffused with ochraceous, deeply
along hind margins; the disk sometimes slightly tinged with purplish ;
the whole surface covered by fine ferruginous streaks ; the bisal space
limited as in the male, enclosing spots similar but faintly colored ; the
submarginal row of black points obsolete or represented by two or
three points at outer angles only, and in all cases minute ; margin at
apex and inner angle, and, on secondaries, the tail and abdominal mar-
gin slightly washed with lilaceous.

This species differs from fnferrnr/afionis in many respects and closely
resembles it in others. It differs in shape of wings, they being more
falcated, more incised ; the hind wings have a longer tail and more
prominent anal angle ; the color is more red, and the hind wings are
red instead of black; the fringes are fuscous instead of white; the
margins are largely bordered by a bright lilac, while those of laterro-
f/ationis are but slightly edged with a dull grey. Beneath, the male of

AMERICAN LEPIDOPTERA. 7

Fahricii is mottled with brown and ferruginous, whereas, the male of
the other species is mottled or marbled in various colors, ferruginous,
cinereous, grey, yellow, brown and purple. There are also differences
in the markings of costa of primaries on under side, and in the com-
mon submarginal spots, these last being conspicuous in one species and
obsolete in the other. The color of under surface of Fahricii 9 is brown
suffused with ochraceous, that of Inter rogationis 9 brown suffused with
blue grey.

On the other hand, the two species are alike in size in both sexes, and
in the markings of fore wings, and in hind wings also, so far as those
are not obscured by black. On the under side the pattern is very
nearly the same, though the colors differ. The legs, palpi, and anten-
nae are the same.

And here I will notice the remarkable resemblance between these
species and G. Commti^ which combines the characters of the other
two. The largest specimens of Comma are equal in size to the small-
est of the others; the form is sometimes that of one, sometimes of the
other, varying much in falcation and length of tail ; the color of upper
side is between the two ; the spots precisely the same ; on the under
side the same words would describe the males of Comma and of Inter-
rogationia, varying only the shades of color. The lines, basal space,
spots, dots, patches, stripes and metallic marginal spots are all the
same except in color. Moreover, individuals of Comma are not unu-
sual in which the silver spot is an interrupted C as in the other species.
I have no doubt, as before said, this species was formerly considered as
a variety of hiterroijatlonis.

(We have also a fourth species nearly allied to Comma, hitherto un-
described, to which I have given the name of Dryas, intending to pub-
lish a full description in the current volume of these "Transactions."
The upper surface of the male is much like that of Interrogationis
male, the hind wings being black. The under side very much resem-
bles Comma, but shades of yellow predominate in the coloring. The
silver C is very slender. Tbe under side of the female is readily dis-
tinguished from all the species by its yellow hue, which is pretty uni-
form, though densely covered with ferruginous streaks. This species
I have several times taken or bred from the larva, at Coalburgh, and
it will probably be found wide spread, though, perhaps, no where
common.)

All three are abundant in West Virginia, and for several seasons I
have had opportunities of watching them in every stage of develop-

8 WM. n. EDWARDS.

ment. All feed upon the same plants, elm, hop, nettle, ambrosia, and,
at the same time, the eggs and the young larvae of each species in
every stage of growth, may usually be found. But I have several times
noticed that the larvae of uniform size, or the eggs deposited on one or
two successive days on a particular plant, produced one species only.
For example, on the 7th of June, 1869, I found on the hop a number
of larvai from one day to one week old and several eggs. The latter
were about J^ of an inch in diameter, green, melon shaped, ribbed
vertically and depressed at either end ; gummed at one end to the leaf.
Under a glass the ribs were prominent — vitreous. As the eggs ma-
tured the color became a bottle green. They were fastened indiffer-
ently to any part of the leaf or stem, the only preference being for
young leaves. Frequently two or more were found one standing on
the end of the other, perpendicular to the leaf. Several times three
were so found, and, in one instance, four. After the larvae emerged
the ribs of the eggs resembled threads, the intervening colorless
membrane being broken.

The larvae, at first, were black, j^^ inch long, covered with black
hairs and short spines. After first moult length j^^, color still black,
but one transverse set of spines, near each extremity, were reddish
yellow. With the next moult the color became black, striped longi-
tudinally with red, and with yellow streaks and dots at base of spines.
These last were in seven rows, many branching, red, or yellow red
tipped with black, except those on first two and last segments which
were wholly black ; this phase continued to maturity, although there
were variations in the color of the spines and in the relative preponder-
ance of black or red. Length, when mature, two inches.

Between the 26th and 30th of June 23 of these larvae had produced
imagos, every one of which was of Interrogationia — 13 S 10 $ .

From the 7th to 21st of August, T found many more eggs and many
larvae, and on the 21st was fortunate in seeing a female Liter rogationis
deposit an egg, from which, in due time, I obtained the imago.

The larvae of i'^ai/vcu were, likewise, black at first moult; black,
with two bars of red and yellow spines at second, but thenceforth dis-
tinctly varied, becoming russet, or reddish specked with fine yellow
papillae, so much specked often as to make the general color rather
yellow brown, than red brown ; the spines sometimes whitish, sometimes
whitish at base and red at tips, with, in all cases, those at the extremi-
ties red.

From these speckled larvae came ^ % \1 ^ Fahricii. From black

' AMERICAN LEPIDOPTERA. 9

striped larvre came 3^39 Tnterrogalionis. But from striped larvae, in
no way distinguishable from the latter, came 1 S 2 9 Fahricii, and frum
speckled larvjvj came 1 S 1 9 Ii'terro'jatlonls.

So that it appears while the striped larvae usually indicate Fahricii
and the speckled Interrogationis, there are casos exactly the reverse.
In previous seasons I had found the same result. I am not sure that
there was any difference in the shape of the eggs of the two species,
though sometimes I thought I discovered that those of Interroyutionis
were equally large at either end, those of Fahricii Vicxe. largest at base.
But I had not a glass of sufficient power to settle the point.

The chrysalids of the two species I was unable to distinguish. They
are well described by Dr. Harris as ''ashen brown, with the head
deeply notched and surmounted by two conical ears, a long and thin
nose-like prominence on the thorax, and eight silvery spots on the
back." Except in shades of color, some being more ashen and some
more brown, I could distinguish no difference. This is more noticeable
because the characteristics are CDUspicuous . It was on account of these
resemblances that Boisduval and Leconte considered the two species
as one. Yet, without any doubt, they perpetuate their kind, and are
to be judged specifically distinct .

The larvae of Comm<t bear no close resemblance to those of the two
larger species, and the chrysalids are quite distinct; which is remarka-
ble, considering the resemblance of the butterflies. The three species
together with Drijas maybe regarded as having sprung from a comuion
type, very near to or identical with Jnfery'ogationis, from which Comma
and Drj/as first diverged, to be followed by Fahricii, the latter not yet
wholly separated from the parent stem, as the similarity of the chrysa-
lids and the occasional interchangable forms of the larvae show.

I intend figuring all these species with the larva3 in a subsequent
number of the Butterflies of North America, and shall be obliged for
any assistance lepidopterists can render me in making their history
more exact and complete.

From 1 S , 1 9 , taken in Oregon by Mr. Wm. M. Gabb. Collection of
Dr. Behr.

This species resembles Alexandra, from which, however, it differs in
breadth and form of marginal borders, in color of fringe, in discal spot
of secondaries beneath, in the presence of a pink spot at base, and in
the absence of a greenish shade to both surfaces. It also differs from
any Colias with which I am acquainted, in the shape of hind wings,
Avhich are remarkably produced at outer angles.

cisco. Taken in the valleys of the Sierra, near A'irgiuia City, in
1869.

This distinct species in the markings of upper side and in the form

outer angle, and a similar curved stripe from median nervure to anal
angle, both wings crossed by a conspicuous submarginal row of black
points or small spots ; on primaries a subapical ferruginous patch en-
closing a lilaceous spot on costa; the incision edged by a brown line
which is preceded by metallic grey lunular spots edged with black ;
similar lunules on secondaries ; costal edge of primaries lilaceous and

some individuals light, the yellow predominating, in others the ferru-
ginous streaks give color to the whole surflice ; submarginal black spots
less conspicuous, and, sometimes, on disk of primaries wanting; margi-
nal lunules as in male, but less distinct; silver spot sometimes as in
male, but usually slighter and not thickened at extremities.

From 4 S , 5 9 , bred or taken at Coalburgh, W. Va., in 1868 and
69. I have noticed the occasional occurrence, for some years, of this
species, but for a long time regarded it as a variety of either Comma
or Interrogatlonis. I am not able now to describe the larvae from
which I obtained the bred specimens. The species is between Comma
and Interrogationu — nearest the former. The under side of the female
differs materially from the female of either species. It cannot be a
common species, but may be wide spread and found in the same dis-
tricts as the allied Graptas.

Three specimens in my collection from different parts of California.
One specimen captured in a warehouse in San Francisco.

The larva of this interesting little insect is not known. As the lar-
vae of Boletohia cai-boHaria, the only one in this most anomalous group
that we are acquainted with, is found to feed on fungi and wood in a
certain state of decomposition, I venture the opinion that a similar
mode of living might be that of our Ayassizia.

Two other specimens of an equally paradoxical interest were col-
lected by Baron Terloot in the Sierra Madre, between Mazatlan and
Durango, and are congeners, if it is allowable to draw conclusions from
specimens that are not perfect in all essential parts.

Size of Ephyra Omnicronarin, to which Geomitride it also bears a
striking analogy in its general appearance. It is, at present, the only
representative of this tropical genus in our State. One specimen from

I am not quite certain as to the identity of this species with that of
Guenee, but as I possess only a single specimen, the differences with
Gu^nee's description might be accidental.

The sober and uniform coloring of the forewings distinguishes this
species from all its congeners. One specimen from Downieville.

I possess five other species of Bollmi from Lower California, and two
from the Sierra Madre. It is very probable that some of them extend
to the southern districts of our state. Most of them belong to the
type of B. Jhcuii<I(i, others imitate in their colouring and markings Ca-

One specimen, caught by Mr. Hoifman of the Geological Survey at
the alpine prairies round the headwaters of Tuolumne River.

This species imitates, to a certain degree, the habits of a Brephos,
but its well defined palpi and the conformation of the two legs remain-
ing to the rather imperfect specimen in my collection, show clearly that
it is far distant from Brephos, and demonstrates its close affinity to the
other species of Si/iieda scarcely modified by an alpine habitat.

Two specimens from Cosala, near Mazatlan, collected by Mr. Bruus,
the superintendent of the mine. I thought it expedient to insert the
diagnosis of this tine insect, notwithstanding its being exotic. To have
the uninterrupted series of closely allied species will facilitate their re-
cognition and prevent mistakes.

I consider myself justified in describing it as a new species.

This and the following species approach very nearly to >S'. graphica
Gn., with which the one or the other might be identical. The figure
of S. grnphicd as given in the Atlas of Guonees Xoctuelites, is deci-
dedly different from bath, as the hindwings of this Sijneda are repre-
sented as being nearly all yellow and only marked by a few black spots.
But that figure, strange enough, docs not agree with Guenee's descrip-
tion, which conies much nearer to <S'. Athnnhra fa, or the following Di-
vergena. As it is difficult to settle the (juestion here in San Francisco,
I consider it expedient to describe and name both species and not to
complicate matters by enumerating a species of whose habitat, in Cali-
fornia, I still entertain doubts.

I have not yet succeeded in finding the larva of any of the species of
this interesting genus. As to its systemat^ical position, I am under the
impression that it is intermediate between Bolina and EucUdla. It
may be that Parthoins Nuhilis of the eastern States is of the same
affinity, and forms a connecting link between Syneda and the Homop-
teriJes. Its affinity to the Catocalides appears to me doubtful, but it
is not time to discuss these questions, as long as the larva state of nei-
ther of them is known.

This species varies, by the parallel undulate lines being more or less
defined, and by a basal space of more saturated tinge, bordered by an
arcuate line vicariating for the interior median line.

All my specimens originate from a brood of caterpillars found in a
garden at San Francisco on a rosebush. They resembled the caterpil-
lars of U. salicis. but were of a darker and more brownish hue.

Synopsis of the FABNID^ of the United States.
BY GEO. H. HORN, M. D.

It is now nearly eighteen years since the publication of the synopsis
of this family by Dr. Lecoute {Proc. Acad., Feb. 1852). In the
meantime a number of species have been added to the list, while many
others from California and adjacent regions, collected by myself, re-
main without names. The object of the present paper is to bring be-
fore the American student a complete list of our species with suffi-
ciently detailed descriptions to enable them to be readily determined.
Several errors in family characters, copied from one author to another,
have been detected and will be mentioned in their proper places.

Among the species described from California, etc., will be found
several genera not before known from the western slope, enough to
warrant the belief that those regions are, at least, as well supplied as
the Atlantic slope. The dearth of species from our Southern States
is remarkable and is the result, probably, of a want of thorough explo-
ration rather than a real absence.

Fully coinciding in the views of Dr. Leconte,the following sub-fami-
lies are adopted :

Abdomen with more than five segments Psephenidae.

Abdomen with five segments only;

Anterior coxse transverse; trochantin distinct Parnidae.

Anterior coxae rounded; trochantin invisible Elmidae.

Sub-Family PsEPHENIDiE.

The characters of this sub-family have been so fully given by Dr.
Leconte (loc. cit. and Clasa Col. N. A. p. 115) that it is not necessary
to enter into details here. Two errors, however, need correction.

In examining the specimens in my cabinet I was unable for a long
time to detect the sixth segment spoken of by Dr. Leconte, which
shows itself on each side only, between the fifth and seventh segments;
those in the cabinet of Dr. Leconte exhibited the additional segments
very plainly. Dissection indicates that those with six segments only
arc females, while the males have an additional segment between the
last and the fifth. Accompanying this are certain antennal differences
not before noticed. The antennae of the male are distinctly stilj-semite
and the last joint at least one half longer than the preceding, those of
the female are almost monillform and the last joint not longer than the
preceding. The hind coxae are said to be contiguous (^Froc. Acad.
1852, p. 41, and Class Col. N. A. p. 115), this I find not to be the
case either in this sub-family or the next, at least, so far as our genera
are concerned.

P. Lecontei, Lee {Eurypalpus) loc. cit; trentonensis Zimm. Trans. Ent. Soc-

The male has the thorax much less opaque than the female, some-
times brownish black in color, in the latter sex the thorax is always
deep black and without lustre ; the elytra vary in color from black to
brownish. The P. trentonensis, Zimm., is not distinct from the other,
and Dr. Leconte informs me that he published the description of Dr.
Zimmerman's in deference only to the very positive opinion of its au-
thor, having doubts in his own mind of its being distinct. Length
.18.-24 inch; 4.5—6 mm.

Occurs abundantly at Niagara and Trenton Falls, and specimens
have been received from Illinois, Rhode Island and Pennsylvania.
P. Haldemani, n. sp.

Similar to Lecontei and differs in being more depressed and with
less distinctly punctured elytra the bases of which have a brownish
testaceous space extending from the humeri to the suture, where it is
broader. The head, instead of being concave, as in the preceding spe-
cies, has two impressions, as if the cavity in the preceding species were
divided by a longitudinal obtuse ridge. The femora are yellowish
and the tibiae and tarsi brownish.

Length .15 inch; 3.75 mm.

Two females from the Peninsula of California, collected by Mr.
Gabb.

Sub-Family Parnid^.
Two tribes form this sub-family.

Head not entirely retractile, free beneath Larini.

Head retractile, protected beneath by prosternal lobe Parniai.

Tribe I. — Larini.
Two genera are included in this tribe, one of which is Californian,
the other European.

LARA, Lee.

L. avara, Lee. loc. cit.

Sufficiently detailed generic and specific descriptions have been
given by Leconte (loc. cit. and Class Col. JV. A., -p. 116), and it is
unnecessary to add anything further. Length .30 inch ; 7.5 mm.

From the circumstances attending the reception of this insect I am
inclined to believe that the high mountain regions of the upper Sacra-

AMERICAN COLEOrTERA. 31

mento Valley form the habitat of this insect. I am quite certain that
I saw a living specimen adhering to a log under water in a swift stream
near Fort Crook.

Tribe IT. — Parnini.
Three genera only represent this tribe in our fauna, distinguished as
follows :

Body rounded; eyes not hairy.

Antennse distant; second joint large; last joint of maxillary

palpi securiform Lutrochus.

Body elongate.

Antennte approximate; eyes hairy; last joint of maxillary

palpi elongate ....Pelonomus.

Antenna distant; eyes glabrous; last joint of maxillary palpi

elongate Helichus.

An examination of all the genera of this tribe has shown me that
the hind coxa3 are very distinctly separated, and cannot be called sub-
contiguous, even iu Farnm, as has been done by Lacordaire, (Grcnera
II, p. 504). The genus Lutrochus may be known by the form of the
epipleuraj which are suddenly lobed in front. The second antennal
joint is large in Helichus and small in Pelonomus. All have the outer
joints of the antennse (4-11) distinctly lamellate, with the joints not
<'-reatly varying in size either in length or width.

superficially by the absence of any lateral thoracic grooves.
P. obscurus, Lee. Proc. Acad. 1852, p. -12.

Length .26 inch; 6.5 mm. Occurs in the Southern and Western

States.

HELICHUS, Erichs.
Jlelichus, Erichs. Ins. Deutsch. Ill, p. 510.

A careful examination, especially of the larger species of the genus

shows the tibial spurs to be quite distinct.

Our species may be distinguished as follows:

Last abdominal segment densely pubescent:

Spurs of tibiffi quite distinct but small productus.

32 GEO. H. HORN.

Last abdominal segment nearly nude, frequently ferruginous in color:

Body finely and evenly, sericeous pubescent lithophilus.

Body coarsely pubescent.*

Basal thoracic region and sutural space glabrous fastigiatus.

Surface everywhere pubescent.

Alternate interspaces more convex striatus.

Interspaces flat '. suturalis.

H.productus, Lee. Proc. Acad. 1852, p. 43.

Our largest species, easily kaown by the last segment of the abdo-
men being as densely coated with scaly hairs as the other segments.
The thorax is nearly square in the males and broader than long in the
females.; surface rather coarsely punctured and sparsely pubescent.
Elytra elongate, subparallel on the sides, striae firmly impressed, with
not large punctures, surface more densely pubescent on the sides.
The sutural space, which becomes wider behind, is less densely pube-
scent, and the hairs are finer, more silken and more easily removed.
In this and the other California species the surface becomes coated
with a whitish material, so thick and dense as almost completely to
hide the pubescence. This is especially the case in those specimens
found in streams the waters of which are strongly impregnated with
earthy salts, and in specimens taken near the end of the season the
legs have been found so completely covered with this incrustation as
almost to interfere with their motion. Length .24 — .32 inch j 6 — 8
mm.

This species is widely distributed occurring from near Santa Bar-
bara, in the Coast Range, to Tejon, thence in the streams to Yuma, and,
in places, along the Gila and San Pedro Rivers, of Arizona, as far as
Camp Grant. The original specimens were found at San Diego and
Mr. Gabb brought others from the Peninsula.

H. lithophilus, Germ. {Elmis), Ins. Spec. Nov. 88; Lee. Proc. Acad., loc. cit.

This species is too well known to need comment. It may be readily
known by the dense and evenly distributed sericeous coating with a
slightly bronzed lustre. The legs are more glabrous than on other
species and, as in all those which folljw, the last ablominal segment
is almost entirely deprived of its pubescence and is reddish in color.
The profile of the elytra from the scutellum to apex is a regular curve.
Length .20 inch ; 5 mm.

* The pubescence is variable in its quality and distribution. That along the
suture, being finer, is frequently rubbed off, either by the motions of the insect
when alive or by frictioa against others in transportation. In one spe-
cies there is a basal thoracic and a sutural space of the elytra normally devoid
of pubescence.

AMERICAN COLEOPTERA. 33

Specimens in my cabinet are from Pennsylvania, Iowa and Canada
West, the latter through the kindness of Mr. Johnson Pettit.

H. fastigiatus, Say (Parnus), Long's Exped. II, 275 ; basalis Lee, Proc. Ac. loc.
cit.
The basal region of the prothorax is rather suddenly depressed,
smooth, shining and entirely without pubescence. The sides of the
elytra are densely pubescent while a sutural space is quite smooth and
with but few hairs. This space is broader at the base, gradually nar-
rowing to the middle of the elytra, then widening, and forming an
oval space not reaching the tip. All the numerous specimens before
me exhibit this, and, in confirmation of the fact that the absence of
hairs is here not accidental, there are very few punctures and the sur-
face is quite shining. The last abdominal segment is as in the prece-
ding species but less ferruginous. Length .20 — .22 inch ; 5—5.5 mm.

Occurs from Canada to the District of Columbia and Illinois.
H. striatus. Lee. Proc. Acad. 1852, 4^;foveaius Lee. loc. cit.

The latter species does not appear to have any definite character by
which it can be separated. The unique specimen on which it is
founded has not the alternation of the interspaces as well defined, and
is, moreover, slightly more elongate. But I am persuaded to overlook
these variations from the fact of still greater deviation occurring in
2irodnctus, with, however, intermediate forms uniting them. Speci-
mens have been sent me by Mr. Jas. Behrens from the neighborhood
of San Francisco, which cannot be separated from the true type. This
species may be known by the alternate interspace being more elevated-
Length .22— .24 inch j 5.5 — 6 mm.

Not abundant in the Eastern States and Canada, but greater num-
bers prevail in the Western States. The California specimens have
been received in abundance, and, judging from my experience in col-
lecting productus, when found occur in countless numbers. 1 have
seen several hundred on a stone not more than four inches square.
H. suturalis. Lee. Proc. Acad. loc. cit.; gilensis Lee. loc cit.,- (xqualis Lee. Proc.
Acad. 1S54, p. 81.

These three species were founded on unique specimens from widely
separated regions. Collections made by myself and others in Califor-
nia and Arizona demonstrate the fact that these should all be united, as
a perfect series, including the types, can now be formed. The sutural
elytral space in specimens devoid of incrustati<in. has the hairs rather
more sparsely placed and paler in color; the form of the space being
similar to that described in fastigiatus. The thorax is, however,

TRAXS. AMEK. EST. SOC. (5) FEBRUARY, 1870.

34 GEO. H. HORN, M. D.

regularly convex and pubescent. The last abdominal segment deprived
of hair and more or less ferruginous. In all the specimens before me
there is a subtriangular space near the middle of the anterior thoracic
margin, smoother and less pubescent. In an examination of the typi-
cal specimens, sequalls and gilensis are exactly similar in form, the
latter being coated somewhat with earthy matter while the former is
clean. The type of sufuralis is in rather bad condition, being densely
coated; is broader in form than the others but resembling the fe-
male specimens collected in California, and which without doubt are
referable to sequalls. Length .20 inch; 5 min.

Occurs with inoductiis but extends further east than specimens of
the latter have been found.

Sub-Family Elmid^.

The anterior coxae are rounded and without trochantln. The an-
tenuce are slender but slightly thickened at tip. The hind coxge are
more widely separated than in the preceding sub-family, and the legs
longer and more slender. The genera and species are more numerous
and, with the exception of Elmis and Ancyronyx., have representatives
on the Pacific Slope.

The genera represented in our fanna may be thus distinguished;

Head protected beneath by a prosternal lobe.
Antennse 11 jointed.

Anterior tibise pubescent internally Elmis.

Anterior tibise glabrous internally Stenelmis.

Antennse 6-jointed Macronychus.

Head free; posternum not lobed ; anterior tibiae glabrous internally.

Antennse 11-jointed Ancyronyx.

In the above genera are comprised all the species in our fauna.
Limnius has been united With Elmis as not being sufficiently distinct,
none of the special characters assigned to it having that degree of per-
manence entitling them to generic value. The line between a rounded
and elongate oval scutellum is not sufficiently distinct, as has already
been shown by Dr. Leconte {Proc. Acad. 1866, 380). The degree of
sinuation of the basal line of the thorax is equally valueless with the
general form; the "tout ensemble" is also a faulty guide, as Elmis,
both in Europe and America, appears rather heterogeneous in the as-
pect of the different species. The first two genera have rather numer-
ous species, the third but two, one of them being Californian, while
the one species of Ancyronyx still remains without a congener.

These three species are closely allied and are difficult to distinguish
in description. All agree in a similarity of coloration an elon^gate
form and, consequently, a more decidedly elongate scutellum. They
have also the prosternal lobe much less prominent than m the species
^hich follow, the parts of the mouth are less concealed beneath, the
head more prominent and the front less deflexed. They differ as fol-
lows ; hiclttatus is the larger form, its thorax is decidedly (at least oue-
third) broader than long, more convex and with the apical and basa
margins and also the sides blackish; the sides are rounded and near

the hind angles slightly sinuate. The elytra may he described as black
with a yellow or luteous oblique stripe, widest at base, extending from
the humeri to the apices of the elytra. Vitfafm has the thorax gradu-
ally narrower from base to apex, feebly rounded on the sides and less
convex than in the preceding species, and much less broad proportion-
ately. The oblique stripe of the elytra does not attain the apex. The
thorax is colored similarly to hiuittatus, but the apical and basal re-
gions are not as distinctly blackened. Quadrinotatiis is the smallest
and most slender species. The thorax is similar in shape to hiviftatus
but entirely bronzed. The punctures of the elytra are proportionately
coarser. The oblique stripe is occasionally entire but not attaining
the apex, usually interrupted at middle, forming a humeral spot and a
stripe in the posterior third of the elytra.
E. elegans, Lee. (Limnius) Proc. Acad. 1852, p. 4.3.

With this species commences a group having an elevated line ex-
tending from the basal line of the thorax to near the middle. Elejans
may be easily dibtinguished from any other of the group by its rather
more slender form and by its elytral ornamentation; the elytra are
black, slightly bronzed, with an oblique luteous band, starting at the
humerus, extending inward to the second interspace and along this in-
terspace to about the middle of the elytra ; another oblique band starts
from near the middle of the lateral margin, runs inward toward the
apex without attaining it. Length .11 — .12 inch; 3 mm.

Occurs in Vermont.
E. fastiditus, Lee. {Limnius) Agass. Lake Superior, 217 ; Proc. Acad. 1852, 4.3.

The sides of the thorax gradually converge and are scarcely rounded.
The form is more elongate and less convex than in ovalis, and the ely-
tral interspace more distinctly punctured. Color bronzed black, with
an entire oblique luteous stripe extending from the humerus nearly to
the apex. The suture is also luteous in many specimens. The legs
are black. Length .11 inch; 4 mm.

Occurs in the Lake Superior region.
E. ovalis, Lee. (Limnius) New Species, 1863, p. 74.

Similar in outline to the preceding but slightly broader, more con-
vex and shining and with the elytral interspaces scarcely punctured.
The sides of the thorax are distinctly rounded aud the disc more con-
vex. The oblique stripe seen m fastiditus is not entire in this species,
always interrupted at middle and much darker in color. Legs black.
It is similar in length to fastiditus.

Occurs in South Eastern Pennsylvania.

E. qnadrimaeulatus, n. sp. — Elongate oval, black, not hronzfd, shining; thorax
broaiiiM- than long, sides very feebly rounded, gradually converging to apex,
disc very sparsely punctured. Elytra oval, sides feebly rounded, above moder-
ately convex, with distinct striae of rather largo punctures becoming smaller
towards the apex, interstices scarcely punctured ; a large liumcral (red when
living) luteotis spot, another more elongate near the apex of each elytra. Legs
luteous. Length .08 inch; 2 mm.

Besides the groove limited on the outer side by a slight carina
seen in the other species of the group, this has a slight rounded im-
pression on each side of the scutellar region of the base of the thorax.
It may be known from the two preceding species by its more elongate
form, deeply punctured elytral strife, and very feebly punctured thorax.
The two spots on each elytron never tend to the formation of a stripe.

In the waters near Fort Crook, California.

E. glaber, n. sp. — Elongate oval, rather robust, black, feebly shining. Tho-
rax slightly broader than long, sides feebly sinuate in front, rounded at middle
and slightly narrower at base, disc with two entire lines extending from base
to apex and a transverse impression at middle between the the two lines ; space
between the elevated lines smoother and less punctured, sides more opaque and
more coarsely punctured. Elytra oval, sides feebly rounded with striaj of mo-
derately large punctures, less distinct at apex, interstices flat, feebly punctured ;
fifth interspace carinate for a short distance, seventh carinate from humerus
to near the apex. Legs and antennae brownish. Length .OS inch; 2 mm.

The space between the fifth elytral interspace and the margin is
more distinctly punctured and opaque than the middle of the elytra.
The humeri have a faintly paler appearance. The species may be
easily recognized by the entire lateral thoracic carina, the transverse
impression, and the two lateral elytral carina).

This species may be recognized by the characters above given. It
resembles greatly our species of Stenelmis in its general aspect, but
the unmistakable line of pubescence on the anterior tibite indicates its
generic place notwithstanding the fact that its appearance caused
me, until the present, to place it with Slenelmis in my cabinet.

E. similis, n. sp. Thorax slightly longer than broad, sides moderately rounded
at middle, slightly sinuate in front, and near the hind angles. Disc with two
broad, oblique folds converging backwards and joining a longitudinal median
fold. Elytra sub-parallel, distinctly striate, striae with coarse punctures,
towards apex scarcely less distinct; near apex slightly sinuate as in abnormis.
Second interval with a short carina, fourth interval carinate, extending three-
fourths, sixth carinate, extending from humeri nearly to apex. Length .OS

This species and pusi/his, Lee, are so closely allied as to be with
difficulty separated. In similis the punctures are more evident at
apex of elytra, the carinate intervals more acute, the thorax more sinu-
ate in front. In jmsillus there is a distinct humeral and sub-apicul
paler spot, in this species the elytra are of a uniform brownish black
color. Both species have a similar formation of the elytral apex as in
abnormis, and the last abdominal segment has a similar incisure on
each side. Pusillus and similis are similar in size.

Occurs in the San Pedro River, Arizona.

at middle of disc ; sides moderately rounded, feebly sinuate near the hind an-
gles. Elytra subpara.llel, moderately convex, with strire of moderately large
punctures not attaining the tip, intervals flat, the third, fifth and seventh cari-
nate, the third very short, the fifth extending nearly three-fourths, the seventh

Our smallest species, easily known by the hitcous elytral vitta and
the total absence of any elevation of the second elytral interval at base.
The carina of the fifth interval is feebly marked at humerus. The
sides of the thorax are nearly straight or at least feebly sinuate, the
hind angles acute but not prominent, the discal channel rather deep
and smooth at bottom; on each side a short lateral carina within which
is a smooth space. Length .10 inch; 2.5 mm.

This may be the species described by Motschulsky (^Etmles 1859,
p. 50), under the name Immerosus, and, if so, the latter should have
priority. The description of this and others is so vague as to leave
considerable doubt of their identity.

The front angles of the thorax are more prominent. The sides in
front are nearly straight at the anterior third and slightly converge

on each side distinct. Second interval distinctly but feebly carinate
at base, lateral carina not prominent; disc of elytra moderately convex,
with distinct striae, which are deeply punctured at base, becoming
gradually more faint towards apex. The luteous stripe is distinct but
not pale. Length .14 — .10 inch; 3.5 — 4 mm.

Occurs in Ohio.

S. quadrimacolatus, n. sp.

Similar in form to crenatus but diflFering as follows : — Thorax more
elongate, sides less rounded. Elytra more convex in both directions;
second interval with a short basal carina, lateral carina very feeble ;
disc with striae of very large deep punctures, less strong at apex but
not evanescent. Humeri with a rounded red spot and a short sub-api-
cal stripe. Legs black, apex and base of tibiae, tarsi, and antennae fer-
ruginous. Length .14 inch; 3.5 mm.

At the middle of the base of the thorax on each side of the scutel-
lum are two small, smooth, puncture like spots, these are seen also in
the next species. The lateral tubercles of the thorax between the dor-
sal channel and the margin are here very distinct, and in the space en-
closed between them and the channel is a rather deep impression. In
form this is the most robust of our species and, with the exception of
linearlA, has the lateral carina of the elytra least distinct.

One specimen. Vermont.

but the hinder two-thirds are rounded in place of being parallel, the
hind angles are consequently less rectangular. The oblique groove
described in hicariiiafus is also quite evident here. In some specimens
the stripes are (|uite dark, and scarcely evident, in others bright add-
ing to the beauty of the insect. With the exception of linearis is our
most elongate species. Length .14 inch ; 3.5 mm.

This species has a thorax louger thau wide, convex, glabrous,
scarcely punctured and feebly pubescent. The sides in front are
nearly straight, gradually diverging from the front angles, then. feebly
rounded and slightly sinuate near the hind angles. The elytra are
glabrous, somewhat broader behind the middle, striate with moderate
punctures at base, becoming fainter and almost impunctured at apex,
interspaces moderately convex at base especially the second and fourth,
seventh strongly carinate, extending three-fourths the length of the
elytra. The space between the carina and the margin of the elytra is
densely pubescent with sericeous yellow hairs. Legs elongate. Length

Occurs in Pennsylvania.

M. parvulus, n. sp. — Elongate, subparallel, black, shining. Head coarsely
punctured and pubescent; thorax sub-quadrate, conve.x, with a slight median
impression and a lateral carina, sides rounded feebly from base to apex. Ely-
tra elongate, subparallel, moderately convex, with striae of large punctures be-
coming smaller towards the apex ; interspaces moderately convex, fourth, sixth
and seventh carinate and crenulate on top, the first two nearly attaining the
apex of the elytra which is finely serrate. Legs moderate, not long. Length
,10 inch ; 2.5 mm.

A curious little species resembling, at first sight, an Elmis near fcr-
ruginem. Easily recognizable by the generic characters. From gla-
bratus it may be known by its smaller size, less convexity, more
strongly punctured stritio, and by the two nearly entire lateral carinje
of the elytra. The thorax is also shorter and regularly rounded, al-
though feebly, from base to apex. The base of thorax is slightly
broader than the apex. The elytra are much less convex and have not
the lateral sericeous space. The legs are usually brownish.

Occurs at Fort Tejoii, California.

Notes on some Genera of COPEOPHAGOUS SCARAB.ffiID.5: of the United

States.

BY GEO. 11. HORN, M. D.
COPRIS, Geoff.
Our species are but few in number and seem hardly to call for a
separate essay, but as several of -them are closely allied and their de-
scriptions widely separated, the present paper may be of advantage to
many.

Two sub-genera are indicated in our fauna.

PINOTUS, Erichs,*(Archiv. 1847, I. p. 109).— Each elytron 7-striate ; hind tibife
dilated at apex, outer edge crenulate, never with an oblique ridge or tooth,
spur obtuse or emarginate at apex ; front iiarabolic, genae in front of eye
oblique, angle obtuse.
This subgenus is identical with Haldeman's Brachijcopris.

COPRIS, Auct. — Each elytron 8-striate : hind tibiaj compressed, outer edge with
an oblique ridge or tooth near the middle, spur long acute; front semicircu-
lar, gense rectangularly produced, angle acute.

C. (Pinotus) carolinus, Linn. {Scarabaeus) Syst. Nat. I. 2, p. 545; Drury,
Exot. Col. I, p. 77, pi. MS, fig. 2 ; Ilald. (Brachycopris) Proc. Acad. Ill, 125.

Our largest species. This species may be further distinguished
from those of the next subgenus by the presence of a moderately deep
excavation on the underside of the prothorax within the anterior angle,
for the lodgment of the antennal club in repose; also, by the absence
of any elevated line proceeding from the coxa; outwards. Length .80
—1.10 inch; 20—28 mm.

Abundant Southwardly and Westwardly of Pennsylvania.

Our remaining species belong to the subgenus Copris.
Thorax opaque, densely, coarsely and evenly punctured anaglypticus, Say.

AMERICAN COLEOPTERA. 43

Thorax more or less shining, Yery unevenly punctured :

Ch'peus obtusely notohed at middle moechus, Lcc.

Clypeus broadly emarginato at middle, between two small,

distant, obtuse teeth remotus, Lee.

Clypeus acutely and rather deejdy notched between two ap-
proximate rounded teeth minutus, Drury.

In addition to the characters given above all our species of this
sub-genus have an elevated ridge extending from the outer angle of
the anterior coxoc to near the anterior angle of the prothorax, while
the depression for the autcnnal club seen in Pino/us is not evident
here.
C. anaglypticus, Say, Journ. Acad. Ill, p. 204.

Easily known from all the species of the subgenus by the dense,
coarse punctures of the thorax. The clypeus is acutely notched at
middle, the angles of the notch obtusely rounded and a slight sinua-
tioa on the outer side of each. The middle of the anterior edge of
the presternum is armed with a tooth, obtuse at tip, which arises sud-
denly. Elytral strias broad, punctures transverse. Length .52 — .70
inch ; .13 — .18 mm.

Abundant from Canada to Texas.

In the southern and western specimens the horn of the head of the
male is frerjuently long. In females or in more northern forms the
horn is very short or reduced to a mere tubercle.

C. moechus, Lee. Proc. Acad. 1854, p. 222.

Similar to the preceding, but differs in having the thorax much
more sparsely and irregularly punctured and not opaque. The clypeal
emargination is a broad notch. The middle of the anterior edge of
the prosternum is acutely produced but not in the manner of a suddenly
formed tooth. Length .70 inch j 19 mm.

Texas.
C. remotus, Lee. Proc. Acad. 1S6G, p. 581.

Tiic middle of the anterior edge of the prosternum is broadly and
obtusely produced. The clypeus is slightly emarginate at middle be-
tween two distant, small obtuse teeth. The hind tarsi are shorter and
broader than in any of our species, the joints 2, 3 and 4 being as broad
at distal end as long, while in all our other species they are nearly
twice as long as broad. Surface shining, thorax coarsely punctured,
nearly smooth at base. Length .54 — .64 inch; 13.5 — IG mm.

Easily known by its small size and smooth clypeus. The front is
acutely and rather deeply notched, the angles of the notch forming
obtusely rounded teeth, bounded exteriorly by a slight sinuation. The
prosternum in front has a rather long acute spine arising suddenly.
The vertex is usually tuberculate though often with a short, slender
horn. Length .32 — .44 inch ; 8 — 11 mm.

Abundant from Canada to Florida and Texas, and to the base of the
Rocky Mountains.

CANTHON, IIoflFm.
The present short review has been prepared in order to place be-
fore the American student the means of recognising our species, as
well as to enable certain of those least known to be recognised abroad.
la his admirable monograph of this genus, Harold has been unable to
place certain of our species in their systematic positions, as many of
the characters made use of by him have not been previously recog-
nized. In this monograph all our species known to him have been
correctly diagnosed. — (^Berlin Eiitom. Zeitschrift, 1868.)

Our species may be arranged as follows: —

Easily recognizable by the characters given in the table. I cannot
agree with Harold in separating corvinus as distinct. Several distinct
varieties may be noted, however;

simplex. — Surface entirely opaque, thorax not punctured. — Oregon.

co?'y»«ws.— Surface entirely opaque, thorax punctured. — California and Ari-
zona.

miVi^ari.s.— Surface ojiaque, thorax less punctured, humeri red, — Cal. (Tejou
and Visalia.)

humeralis. — Surface less opaque, thorax less punctured and shining ; humeri
polished. — California (Coast Mts. South).

The transition from those with impunctured thorax and those in
which it is so punctured, is so gradual as not to be at all defined.
The slight transverse plication of the elytra behind the humeri is an
individual character, some have it and many more are without it.

Harold appears to have known but one specimen of sim2)Ir.c. My
own series is large, and my observation in California leads me to con-
sider all these forms as mere local varieties and not distinct species.

This species is entirely too well known to need comment. Several
varieties, all having the thorax and elytra distinctly granulate may be
noted.

Obtusidens, Zeig., in which the teeth of the clypeus are barely distinct.
These are usually old specimens and have the teeth of the anterior tibifie also
obtuse.

Viridcscens, Lee, (Coll.) — Surface bright green. The clypeus normally
dentate.

The more general color is a dull black with a tinge of copper.

C. chalcites, IlaUl. Proc. Acad. 1, 304.

I cannot agree with Harold in uniting this with the preceding.
The elytral sculpture is similar, but the granules are more sparsely
placed. The thorax is finely and intricately rugose and not granulate
as iu Isevis. I have seen specimens of the latter in which the thorax
was quite smooth, yet very evident traces of the granules remain in
smooth round spaces between which are the finer granules, visible
even in strongly granulate specimens only under high power. The
form of chalcites is more robust, being shorter and broader than Isevis.
Length .50 — 70 inch ; 13 — 19 mm.

AHECHANTIS, nov. gen.

The above generic name is proposed for our species of Atliyreus, of
which there are three, differing from that genus by the scutellum
being broad, triangular with the sides rounded, and not depressed
below the level of the elytra. The very narrow linear and depressed
scutellum is seen only in Athyrexis and Stenospidius in the group
Geotrupini, while the form of scutellum of our species is very similar
to that seen in the Geotrupes or Bolhoceras.

When viewed from the front (or lower side x,

when the legs are extended) the middle and \***v \ V
hind tibiae present two distinct forms of apex, -^\ ^

(Athyreus), Abh. Berl. Ac. \Si^ ; furcieollis, Cast. Hist. Nat. II, p. 104.

Brownish or ferruginous, not shining. Viewed from above the
head ( S ) is flat, anteriorly truncate or feebly emarginate, sides of
front straight, genae produced at a right angle, with the outer angle
also right. The head of the female is furnished with an obtuse tuber-
cle. The sides of the thorax are gradually rounded from base to apex
and not serrate. Length .75 inch j 19 mm.

Southern States.

A. fossatus, Hald. {Athyreus) Proc. Acad. 1853, 362.

Similar to ferruginous in color but more shining. The head of the
male is strongly bisinuate in front ; the sides of the thorax are gradu-
ally rounded from base to apex but sinuate and finely serrate near the
anterior angle. The thorax is suddenly elevated in front, the anterior
angles of the elevation acute and project outward, on each side a deep
groove or fossa limited exteriorly by an obtuse tooth-like elevation.
In ferrvgincus the thoracic ornamentation is similar but the angles of
the median prominence are turned upwards and the lateral fossae less
deep. Length .75 inch; 19 mm.

Texas. Only males are known.
A. serratus, Lee. (Athyreus) Proc. Acad. 1854, 80.

Differs from both the preceding species in the form of the middle
and hind tibiae as well as by having the thorax strongly serrate. The
elytra are smoother, the striae less distinct and scarcely punctured.
In both sexes the head resembles the form seen in the female of fer-

AMERICAN COLEOPTERA. 49

rnghieus. The vertex is flat in the male but with a transverse eleva-
ted ridge or short transversely flattened horn in the female. The tho-
rax is less abruptly elevated in front than in the other species and the
processes less strongly developed. When viewed anteriorly the thorax
presents a faint median groove, on each side a deeper fossa bounded
by an obtuse elevation. On each side of the thorax is an acutely ele-
vated line proceeding upwards from a short distance behind each an-
terior angle, parallel with the base of the thorax. Of this lateral
ridge no trace is found in either ferrur/ineus or /ossatus. Length .46

melebmus. Fab. Syst. I. 20 ; VVestw. Trans. Linn. Soc. 1852, p. 2S, pi. 4, fig. 26.

The body is uniform castaneous in color, smooth and shining. The
elytra have never more than five punctured stria) between the suture
and humeral prominence. The well developed males have a flattened
horn arising from the clypeus, slightly recurved and truncate or emar-
ginate at tip. There is also an elevated transverse line on the vertex.
The club of the antenna) is elongate oval in both sexes, with the first
joint smooth and shining. In the females the clypeal horn becomes
a ridge, while the vertical ridge seen in the male is more prominent.
Length .20 — .50 inch; 5 — 13 mm.

This species is distributed over the entire region east of the Rocky
Mountains.

This species is much more robust than the preceding. The Cdlor is
yellow with the tibia) occasionally darker. The head is black, also a
narrow space along the base and sometimes a discal spot of the thorax.
The elytra have the first interspaces black, also a subapical space be-
coming at times so large as to to involve more than half the elytra.
The males have the anterior edge of the clypeus and the angles of the
gena) acutely but slightly elevated. The horn is always short, acute
at apex, and arising from the vertex. The females have merely a

transverse ridire on the vertex, slightly sinuate on top. The thorax
of the female has in front an elevated ridge. The male has in addi-
tion a deep fossa below each end of the ridge, bounded exteriorly by
an acute elevation. The ends of the ridge are also elevated into an
acute tooth-like process. After a very careful study of many speci-
mens I cannot but consider as one species, the two forms about to be
described.

Two varieties may be distinguished in this species : —

a. — tumcfactus, Beauv. — Elytra with seven strice between the suture and hu-
merus.

b. — farctus, Fab. — Elytra with five strife only.

The less number in the latter form is caused by a partial or total
obliteration of the 2nd and fifth stride. The autennal club in both
forms is broadly oval or round.

This species is as widely difi'used as the preceding, and is similar
in length, being, however, broader and more convex.'

ODONT.EUS, Klug.

This genus may be readily known from the preceding by having
the eye entirely divided by a narrow process of the anterior canthus.

Three species are known from the United States.
0. filioornis, Say {Bolboc.) Journ. Acad. 3, 211.

Pale castaneous or ferruginous in color, shining. The male has
the horn movable as in the European species. Length .34 inch;
8.5 mm.

Middle and Central States.
0. cornigerus, Mels. {Bolboc), Proc. Acad. II, 138.

Similar in color to the preceding, but occasionally black. The
horn is less slender than in Jiliconiis and fixed. This species attains
a somewhat larger size than the preceding and is usually more robust.

Middle and Central States.
0. obesus, Lee. Proc. Acad. 18:39, 282.

Of this species both sexes are now known. It is larger, more robust,
with the elytral strioo less deep and closely punctured. The base of
the thorax is much less sinuate than in either of the preceding species,
and the hind thoracic angles are rectangular. The sides are gradu-
ally narrower from base to apex and rather feebly rounded. The
male is rather smaller than the female and differs from the male of
cornigerus by a less densely punctured thorax, with regularly but feeb-
ly rounded sides. The processes from the upper surface on each side
are acute at apex. Frontal horn fixed. Length .44 inch; 11 mm.

Occurs at Table Mountain, south of San Francisco, Cal.

BIOLOGICAL NOTES ON DIPTER A.— (Article 2nd.)

BY R. OSTEN SACKEN.

I.— A new American ASPHONDYLIA.

In a previous paper (Trans. Am. Ent. Soc. 18G9, p. 299,) I have
attempted to give a closer definition of the genus Aqjhondj/Ua, and
have described the first American species of the genus, Ai^phondi/h'a
moudrha, n. sp., producing a gall on SoUdago. In the same paper
I mentioned a second, as yet undescribed species, Aqdiondijlia heli-
anthi fjh/jidus, Walsh in litt. Recently, a third species has been
added to the list, producing a large flower-gall on Rudheclcia. It has
been communicated to me by Mr. Jacob Stauffer,iu Lancaster, Peuna.,
together with drawings of the gall.

Concerning the gall, Mr. Stauffer writes as follows : " On the 21st
of Au"-ust I met with very large galls, formed on the flower of Rud-
herkia triloba ? They were in one case nearly round, of the size of a
large apple ; the other was an aggregation of galls of various sizes,
forming a large excrescence."

In a few days the fly was obtained in numbers, as well as a parasi-
tical hymenopteron, a C/u///7no/?jf, apparently identical with C.adccua,
O. S., which I had previously obtained from the gall of Diastrojdius
ncbidosus on blackberry bushes.

Asphondylia rudbeckiae conspicua,n. sp.— About 0.18 of an inch long. Gray-
ish brown, Ihora.x: above oi)aque, grayish, with rows of bhickish hairs; abdomeu
brown, with paler hairs; halteres brown; feet almost uniformly brownish,
(paler when the hairs are rubbed oiT) ; wings rather dusky; the vein ending in
the apex of the wing is gently arched towards its tip. Ovipositor dark brown ;
(described from dry specimens).

This Aqjhondi/lia shows the most important characters of its con-

52 R. OSTEN SACKEN.

geners, as defined in my previous article (1. c. p. 301). Its antennne
have the same structure, but, being mutilated in the specimens I
have before me, do not allow a closer comparison. The ovipositor has
the flattened cylindrical shape and horny consistency peculiar to the
genus and the long, needle shaped, stiff" organ projecting beyond it.
What puzzles me about it, however, is, that whereas in two of the fe-
males which I bave before me, the ovipositor (exclusive of the needle
shaped organ) is very short, not longer than the abdominal segment
preceding it, in a third specimen it has almost half the length of the
abdomen. The pupa; are exactly like those of the other Asplion(l_yJise
which I have seen, and also have the frontal projections contitjiious,
and not remote. A. /-udbeckise conspicua at first sight is not unlike
A. helianfhi g/obuhiK, Walsh in litt, of which I owe a specimen to the
kindness of my lamented friend. Walsh's species, however, is easily
distinguished by the paler color of its hind tibiae and tarsi. Its gen-
eral coloring is also paler brown, with a yellowish-gray pubescence ;
its coxae are pale; the vein ending in the apex of the wing is less
arched than in A. rudhechise lonspicna.

A. helianthi globulus, Walsh, forms a rounded swelling on the stem
of Hefunithus. As it has never been described these notes may serve
to identify it.

II.— On some undescribed Galls of CECIDOMYIA.

In addition to the deformations on plants, produced by Cecidomi/iee,
which were described in my previous papers (^Monogr. of N. A. Dipt.,
Vol I., Prgc. Entom. Soc. Phil., 1866, p. 220, and Trans. Am. Ent
Sac, 18G9, p. 299), I give here a few new cases observed by me.
Although I have not been able to rear the perfect insects from these
calls, I deem it useful to draw the attention of collectors to them.
The description of the gall, coupled with a short notice of the peculi-
arities of the larva, will help to recognize these cases easily.

Cecidomyia sambuci umbellicola, ii. sp.

Among the luubols of the elder (^Sambitciis racanosa) in June,
1868, near South Orange, N. J., I observed some buds of the flower-
lets which were considerably enlarged (from six to ten times the size
of an ordinary bud), their shape remaining round. Inside of each of
guch buds I found an orange larva with a distinct breastbone and with
two minute horny points, directed upwards, at the anal end of the
body. The latter character, not uncommon among Cecidomyise, has
been mentioned by me in the Monographs of X. A. Di'ptera, etc., I.,
p. 181.

AMERICAN DIPTERA. 53

Cecidomyia caryae nucicola, n. sp.

Green husk of tlie nuts of the shell-bark hickory (^Carya aILn), de-
formed by swellings, giving it an irregular appearance. When cut
open the bumps showed small round cavities on the inside, often two
or three together, each containing a pale reddish larva. Its breast-
bone is distinct, elongated, narrow, its branches short and square, end-
ing in sharp angles anteriorl}', instead of being rounded ; the emargi-
nation between them broad and deep. Anal end of the body smooth.
In one case, the husk of a small nut, thus deformed, had burst open,
leaving the nut uncovered, although it was yet far from being ripe ;
what remained of the husk formed several wart-like swellings on the
basal portion of the nut.

Found August 0, 18G0, near Rhiuebeck, X. Y.

Cecidomyia tilise citriaa, n. sp.

Swollen and deformed terminal buds on young shoots of the linden
tree (7'i/ia a mrricaiia~). The gall thus formed is irregular in shape.
with leaves growing out of it; its flesh moderately succulent. The
cavities inside are filled with bright lemon-yellow larvae of Cecidomi/in.
Breast-bone small, but distinct; the excision on its anterior edge is
unusually deep.

On the leaves surrounding the larger galls, the same gall occurred
in the shape of a small round swelling of the midrib ; its identity with
the larger gall was proved by the presence of the yellow larviu inside
of it.

Found in July, 18G9, near Sharon Springs, X. Y.

Cecidomyia qaercas majulis, n. sp.

]Jlister-like gall of Cecidomyia on young leaves of the pin-oak
( Qucrcus palustriii).

Generall)', these galls occur on the principal ribs of the leaf; sonje-
times between the ribs. They are oblong, blister-like, hollow ; surface
somewhat uneven, wrinkled, walls thin ; color pale green or reddish.
They bulge out on one side of the leaf and have a longitudinal slit on
the other. Galls projecting on the under side of the leaf and having
the slit on the upper side seem to be somewhat more common than
those of the opposite description. The slit can be opened without in-
juring the gall by gently pulling at the sides. Such galls which grow
upon a rib show a trace of it on their longitudinal diameter. The
larva, which can be taken out of the slit without lacerating the gall, is
rather larger than the majority of the larvae of Cecidomyia, (about 0.2
of an inch long.) and not reddish, as usual, but white, smooth ; the

54 V R. OSTEX SACKEN.

breast-bone is hardly visible, as its front part only is horny, having the
appearance of a transverse, reddish-brown wavy line. The last abdo-
minal segment has several minute, fleshy-pointed projections. The
larva drops to the ground through the slit at a certain period of its de-
VL'l )pnieiit ; hence, empty galls are often found.

Found ill considerable numbers in the Central Park, N. Y., in May,
1869.

I.— New Observations on the Gall of CYNIPS QUESCTJS PALUSTRIS, 0. S.

Among the oak galls described in my previous articles, one of the
most singular is the gall I named Cijnipa quercus palustris, from its
frequent occurrence on Q. palustn's, the pin-oak, although it is also
occasionally found on other oaks of the red-oak group. This gall is
especially remarkable on account of a small, cocoon-like body, contain-
ing the pupa, which rolls freely about in a comparatively large cavity,
without being connected in any way with the walls of this cavity, or,
in other words, with the substance of the plant upon which the gall is
growing. An examination of the shell of this cocoon-like body (which,
for brevity's sake, I will call ovule} proves that it does not consist of
animal, but of vegetable matter, in other words, that the ovule is not a
cocoon, although it contains the larva ami afterwards the pu])a. The
growth of these galls is so sudden that, although I have seen thousands
of them, I do not remember having seen one which was not full grown
as far as the size is concerned. Once or twice only I discovered spe-
cimens arrested in their growth by some unknown agency and withered
in that state; and in such specimens 1 observed the ovule still con-
nected, by a short stem, with the leaf or branch upon which the gall
was growing. It would seem, therefore, that the ovule is nothing but
the usual kernel, existing in many other galls, but which here, during
the growth of the gall, becomes disconnected from its shell.

During my rambles in the Central I'ark, in New York, in May,
186'.), among numberless galls of this kind on tlie pin-oak, I observed
a good many which were double, that is, consisted of two galls sold-
ered together. Such galls instead of globular were oblong, sometimes
slightly narrowed in the middle. Usually, there was no partition on

A:\IKRICAX IIYMENOrTEUA. bo

the inside between the two galls ; in the cavity thus foniicil was the
likeicise douhh ovule. The coarctation in the niiiklle of the ovule was
generally much uiore niarkod, than that of the gall. The double ovule
contained two well-formed pupfc without any partition between them,
and hence almost in contact with each other.

Such double galls showed difierent degrees of coalescence, and the
coalescence of their ovules was always in exact proportion to the coa-
lescence of the outer shells of the galls. Sometimes the galls, although
coalesceut externally, were still separated by a partition internally;
then each gall contained its own ovule. But whenever there was no
inner wall between the galls, the ovules were also coalesceut. In one
case I observed the inncM- wall only partially removed, the cavities
communicating by a rather small opening ; the ovules were in this case
coalesceut by a small portion of their surface, otherwise retaining
their rounded shape and thus almost representing the figure eight.

In one of the galls I observed a small green caterpillar with yellow
stripes, which luid taken its abode in it and eaten up a part of the
ovule, and perhaps also sacked out the larva.

II. CVMPS Q. NOTIIA, n. Sp.

Still more remarkable, perhaps, than the preceding observation, is
the discovery, among large numbers of the gall of C. q. pahoitrix, of
another gall, constructed on the same principle, that is, with a movea-
ble ovule on the inside, but entirely different in tlu' details of its or-
ganization.

This gall, growing on the same trees and in exactly the same situa-
tion with that of C q. j^rthistris, often alongside with it, is, however,
much more rare. Its shell is not globular but oblong, much thinner
and hence less succulent than that of C. q. palustn's. Its green sur-
face shows some longitudinal, semitransparent veins, of which there is
no trace in the other gall. The ovule likewise is different; instead of
round it is elongated, rounded at one end, pointed at the other, resem-
bling a seed very much; its outer shell is much harder, smooth and
shining. One of these galls had coalesced with a gall of C. q. p((/i(s-
tn's, just in the same manner as the above mentioned double galls of
the latter kind. And, singular enough, the ovule of this double gall
showed, by its unsymmetrical shape, that it was the compound of the
ovules of the two different kinds. (I have preserved the specimen in
my collection.)

I obtained several specimens, male and female, from these galls,
which showed no perceptible difference from C. q. jmlustris. What

56 R. OSTEN SACKEN.

the different shape of the gall means, is a mystery to me. Until this
is solved, I propose to call the gall Quercus noiha, in order to distin-
guish it from the other. It may be that the flics themselves, upon ,
closer examination, would show some specific differences. Both galls
excluded their flies between the 20th and the oOth of May.

III. — CYNiPS QUERCUS ECHINUS, n. sp. — (From California).

Echinus-shaped, ptnki.sh red gall of hardened gallic acid, on the
leaves cf Quercus ar/ri/olia.

The gall, fastened to the underside of the leaf, consists of a globular
body, covered with numerous pointed processes, which are not much
shorter than the diameter of the body of the gall, the latter being from
0.2 to 0.3 of an inch. The inside of each gall contains a single insect
in a small cavity. 3Ir. W. M. Gabb, to whom I am indebted for this
gall, discovered it in Placer Co., California, in the low hills of the
Sierra Nevada. According to his statement, the galls, when fresh, are
of a bright scarlet, a little lighter at the tip of the processes. The
substance of this gall is hard and brittle, consisting apparently of
pure gallic acid. This gall belongs, therefore, to the same class with
that of equips quercus tubicola, 0. S. In both cases the leaves bear-
ing the galls are not deformed at all, and the galls, when detached,
leave hardly any trace behind them.

These galls reached me from California quite fresh, and in cutting
some of them open I found the Cijnips still alive. They seem to be-
long to the genus Cjjnips in Ilartig's restricted sense.

Cynips quercus echinus, n. sp. — 9 0-14 of an inch long. Brown, mixed with
reddish-brown; head, thorax, antennae and feet with a grayish jmbescence.
Head reddish brown more or less darker in the middle of the front and vertex;
antennte brown, somewhat stout; 14-jointed, the third joint long and slender,
the following gradually decrease in length up to theSth ; the 6 last joints short,
subequal. Thorax reddish brown, with a dark brown stripe in the middle, and
two similar lateral stripes which are abbreviated in front; scutelhim ellipsoi-
dal, brownish. Abdomen brown, shining, hind margin paler; basal part of the
second, largest, segment densely pubescent on the sides ; this segment is sub-
triangular, the following ones project very little beyond it; ventral valve with
a tuft of yellow hairs. Feet reddish brown, mixed with darker spots. Wings
subhyaline; stout veins clouded with brown, especially the transverse vein
above the areolet, which has a distinct brown cloud upon it; tip of the radial
vein expanded into a brown dot; a brownish, elongated cloud in the anterior
half of the cubital area; two or three small, indistinct streaks of the same color
in the posterior half of the same area; another pale cloud in the next following
area, below the areolet: and still another on the anal vein, close by its usual
interruption.

IV. — On some .species of Callimome, parasitic on galJs.

The nuiuerous parasites infest'm<; the galls of Cijnipidfe and Ccciilo-
myix^i afford a most interesting aud yet entirely unexplored field of re-
search. IJesides the inrjuilinous Ci/nipid,ie,, like Aidux, Cnroptres^
Sj/>icr(ji(s, a large number of other insects is obtained by those who
collect galls for the purpose either of preserving them, or of rearing
the gall-produeing insect. Most of those belong to the family of Chal-
cidiiliv, and especially to the genera Ca/limome, Onni/rux, Eunjtoma
and Decdtonia. Here and there species of Pteroinaliis, l^e/nisfichiis,
or a wingless Enpi'hnus are obtained. That the economy of gulls is
not confined to llymenoptera alone, is proved by the fact that more
than once I have obtained a Coleopteron, Hjjdiiocc.ra verticalis, from
galls in my breeding-boxes, (compare Proc. Ent. Soc. Phil. 1861, pp.
68 and 71). The curculio O/idocepha/us amcricanns also occasion-
ally takes its abode in the coiky substance of a gall, (compare 1. c,
P-6S).

Various are the relations in which all these species stand to the
gall-producing insect, and it is in this direction that a great deal re-
mains to be observed and studied. It seems that while the inquilinous
or parasitical Ci/nipidx (^Aulax, Synerr/tis, etc.,) live in the gall with-
out attacking, although probably often injuring, the gall ]»roducing
equips, the Chalcididse are real parasites, the larva; of which live afc
the expense of the larva of the gall-producer. But here, again, the
questions how and when the eggs were deposited, what influence the
parasites have on the growth of the gall, what difference exists be-
tween the mode of life of a Callimome and an Onnjrus or some other
genus — all these questions remain unanswered.

My purpose in the present paper is merely to describe a few species
of Callimome, obtained from galls by me or by others. I have con-
fined myself to the most striking forms, omitting a good many species,
which, from want uf well defined plastic characters, I could not suffi-
ciently characterize.

Species of Callimome are obtained from galls both of C;/ni]>idii and
Cecidomjiit., and hence, although the series of papers to which the
present one belongs, treats of the natural history of the (\i/iiij,ld-rr only,
I could not well omit the mention of those species of Callimome which
infest the galls of (.'ecidomi/ia. In one case (C advrua^, it seems
pretty certain that the same species was bred from the galls of a Cj/-
nips and of a Cecidomi/ia.

If, on one side, the same species of Callimome infests galls of differ-

ent kinds, on the other, different species of CnUhnome are occasionally
bred from galls of the same kind. Thus, both C hrcvicauda and C.
advena were obtained from the gall of DiuHfrophus nebidosux^ 0. S.
C. magnljica and C. fiavicoxa (perhaps also C. solitaria), were bred
from the gall of Rhudites radicum.

Considerable materials for the present paper I owe to the communi-
cation of Mr. Norton, who had obtained a large number of Callimome
from galls on the rose.

As, owing to the difficulty of this genus, doubts may arise concern-
ing the identification of some of my species, I have deposited the types
of my descriptions in the Museum of Comparative Zoology in Cam-
bridge, Mass.

Head metallic green; mouth and its surroundings yellow, which color is
more extended in the 9 than in the"^; scapus of the antennae yellow, the rest
black; front and vertex microscopically sculptured. Thorax yellow, except
the scutelhun, which is green, and a shining green spot on the jdeurre, above
the middle cox£e; besides, in the *£ the upper part of the mesotliorax is green,
which color also somewliat encroaches on the prolhorax; in the 9 this color of
the back is less extended, more faint, and has a somewhat bluish tinge. Me-
tathorax green in the'^; yellow, with a bluish tinge, in the 9- The scutellum
is very minutely sculptured and has, also, some scattered and indistinct punc-
tures which can only be perceived under a high magnifying power. Abdomen
yellow, more or less tinged with brown on its upper side at the base, and on its
latter half; the basal brown space has a metallic green reflection ; the apical
one is somewhat bronzed; both have more or less extent in different specimens,
so that the yellow interval between them is more or less narrow; the undei'side,
which is usually yellow, is also more or less encroached upon by the brown of
the upper side ; ovipositor brown, about equal in length to the body without
the head ; feet yellow, tarsi whitish ; onychia brown : wings hyaline : costal vein
slender.

One S and two 9 specimens, reared from the gall of Laxiopfrra vilis,
O. S., on the wild grape, near Washington, D. C., (compare my paper
on Cecidomijia in Loew's 31onographs of N. Am. Diptera, p. 201.)

2. C. dura, n. sp.

From the gall of Di'phsis canjx (1. c. p 191), I have reared a sin-
gle male specimen, larger than the S of the preceding species, as it
measures 0.1 — 0.11, but resembling it in the distribution of the colors,
except that the head is altogether green, there being no yellow round
the mouth, and that the prothorax is green above, and yellow only
below. The costal vein of the wings is much stouter.

Five specimens (two Sand three 9 ), apparently of this same spe-
cies, were communicated to me by Mr. Jacob Stauffer, Lancaster, Pa.
He bred them from the gall of Aspliondjjlla rudbeckfse conxpicua, 0. S.
The tibias of one of the males are a little paler ; otherwise, I do not
discover any differences.

The face is sparsely, but rather distinctly punctured and clothed with soTne
scattered, short, whitish hairs; mouth yellowish-brown ; vertex bluish-green,
serieeoiis. Antennae black, scapus of the 9 yellowish. Thorax green, with a
very slight tinge of bluish, rendered sericeous by dense, microscopic trans-
verse striaj ; it is even except some indistinct, shallow, scattered impressions,
visible only in a certain light; a very sparse, short pubescence is also apparent.
Pleurae green, partly bright blue. Abdomen green, or bluish-green, bright,
shining. Ovipositor of the 9 about the length of the body. Hind coxre with a
distinct brownish, metallic tinge; their anterior part, however, generally green
or blue. Femora metallic green, except the very tip, which is yellowish.

Reared from the galls of Ci/nips qnercus tubicola, three S and a sin-
gle 9 specimen. Washington, D. C.

A good many species will be found closely allied to this, and, there-
fore, difficult to distinguish from it. I possess one male and two fe-
male specimens, apparently of the same npecies, perhaps a trifle larger,
which have been obtained from galls of Cijiilpa (jncrcm lann.

A single specimen, obtained from C^iiij)^ q. siiit/nJaris, Bassett, be-
longs, evidently, to a different species. It is larger, gveen, with very
little bluish reflections, ovipositor considerably longer than the body,
anterior tibiai paler, etc. Another still larger specimen (source un-
known), is of a more brilliant green; all the tibias are yellow; the ovi-
positor likewise very long.

AMERICAN HTMENOPTERA. 61

5. C. flavicoxa, n. sp. — Coppery green, feet yellow, hind coxa yellow, bright
preen at thebasi-i; anterior half of the Hbdomen yellow; posterior purplish
copj)ery ; a slight shade of yellow in the middle of the forewings. 9 about O.l.'',,
ovipositor 0.10 of an inch long.

Face shining green with a golden reflection, very finely (almost microscopi-
cally), and sparsely punctured and pubescent ; front more coppery and rather
opaque. Antennre black; scapus, except its tip, yellow ; mouth yellow on the
underside, mandibles somewhat brownish. Ground color of the thorax a ra-
ther dull metallic green, more or less tinged with coppery; this coppery tinge
sometimes aj^pears principally on the prothorax. sometimes it extends, also,
over the whole mesothorax : there is, usually, (although not always) a darker
spot on the anterior part of the prothornx, near the junction with the head,
which spot, in some specimens, has a beautiful purple color. The narrow hind
edge of the scutellum, separated by a furrow, and the metathorax are sometimes
of a more intense green color. Pleurae shining green. The surface of the tho-
rax, including the scutellum, is finely, although not very densely, punctured.
The metathorax is smooth, with the usual microscopic sculpture on its sides.
Abdomen brownish-yellow; a metallic green spot near the extreme basis
above; its posterior half coppery, with a purplish reflection. Feet, including
coxae, yellow; hind coxae green at the basis, on the extent of which color they
are finely and densely sculptured; basis of the tarsi whitish. Wings grayish
hyaline; a pale yellow cloud or streak occupies the middle of the disc, hardly
reaching beyond the stigmatical branch.

Six female speciuieus, reared by Mr. Norton from the gall of Rho-
ilites radiciim, O. S. The C. ma(jnifica, as stated above, was reared
from the same gall, and it is singular that both species should have
two rather unfreijueut characters in cominun, the spot on the neck of
the prothorax and the cloud on the disc of the wings.

I possess specimens of a Callimome very like the preceding species,
but distinguished by some constant characters. I found three 9 ^"id
fiveS specimen.s of this kind in a box, containing the common black-
berry gall; but I am not positive about their having escaped ffnni this
gall, as I had kept some rose galls in the same box before.

The female specimens diU'er from those of C. Jiuvicoxa by a slightly
larger size, a distinctly longer ovipositor, which is almost as long as
the bjdy without the head, the more handsome green color of the tho-
rax, the bluish base of the yellow hind femora and the much less ex-
tended purplish-coppery color on the hind part of the abdomen, which,
in some specimens, is brownish-yellow with a slight tinge of co|i])ery
or greenish near the tip. The male specimens resemble the females,
only the abd^micu is altogether of dark color, with a transverse, yellow
band upon its anterior part, which separates the greenish basis ii-om
the coppery or purplish posterior part. The basis of the hind I'eiuora
in some of the specimens is green, instead of blue. A yellowi.-li cloud
on the forewings is not perceptible.

6. C. brevicauda, n. sp. — Green or bluish-green, abdomen with a reddish or
coppery rollection ; fore eoxse 3'ellow, with a green spot near the base, feet red-
dish yellow. Ovipositor of the J not longer than the abdomen; metathorax
deeply rugose. 'J, about 0.12 — fl.lSjjO.H; ovipositor about 0.06 of an inch
long.

Head green, with some golden or bluish reflections; mouth yellowish-brown;
face finely punctured and sparsely pubescent; front sericeous in consequence
of very dense microscopic striae; antennae black, scapus yellow, first joint of
tlie tiagellum green. Thorax green or bluish, microscopically rugose and
punctured with moderate density; hind border of the prothorax with a more
golden reflection. Latter part of the scutellum separated by a transverse row
of punctures, more green or golden-yellow than the remainder, microscopically
rugose, Pleurse more light green between the fore and middle coxse ; a bril-
liant, smooth, sometimes coppery spot above the middle coxse. Metathorax
deeply rugose, not shining. Fore coxse yellow with a green sjjot near the basis,
anteriorly. Middle coxre green at the base, the remainder yellow. Hind
coxre green, densely punctured ; their tip yellow. Feet yellow ; tarsi slightly
whitish at the base. Hind femora sometimes with a slight green reflection on
the outside, which is often wanting. Seen from above, the metathorax and
the inner side of the hind coxre appear blue. Abdomen green at the base ; the
remainder more coppery. Ovipositor very short, not longer than the abdo-
men. "Wings hyaline. The 9 with a pale, yellowish tinge in the middle of the

plish red spot near the junction with the head; abdomen blue or greenish at
tlie basQ. purplish and coppery towards the tip; ovipositor longer than the
body.— -J) about 0.14; 5—0.16—0.17; ovipositor 0.21—0.23 of an inch long.

Face with a golden reflection, rather smooth and shining and only with in-
distinct ami scattered punctures; a distinct, longitudinal carina in the middle;
pubescence whitish, short and very scarce. Mouth yellowish-brown. Front
generally purplish-red in the middle. Antennae black, scapus yellow, infusca-
ted, and with a greenish reflection on the upper side, especially towards the
tip. Thorax green, or bluish-green, with moderately dense, eipially distribu-
ted punctures, visible under a moderate magnifying power; pubescence very
delicate; on the prothorax, above, near the head, there is a pur])le spot,
of variable size, but never reaching the hind margin of the prothorax ; meta-
thorax smooth, shining ; pleurae usually with a coppery spot on the prothorax,
a golden-green, sometimes slightly coppery, finely striated space behind it, be-
tween the fore and the middle coxae, and a j>erfectly smooth, shining space
above the middle coxae. Fore coxae green at the base, yellow on their latter
half, which color extends on their inside much further towards the base than
on the outside. Middle coxae green, their latter half yellow. Hind coxae
green; their tip yellow. They are, as usual, finely sculptured, but thiir sculp-
ture is less deep and dense than in C hrcvis, tubico/a, advena, etc.; the coxae,
therefore, are not opaque, as in those species, but preserve their lustre. Feet
yellow; tarsi whitish at the base ; this color is most extended on the middle
and hind tarsi; tip of all the tarsi brown. Knees also somewhat whitish.

AMERICAN ITYMKNOPTERA. 63

Abdomen usually shining, blue at the base above ; purplish towai-ils the tip
above; below more coppery red. Pubescence scattered: very distinct in the"^.
Ovipositor very long; wings with a very pale brownish yellow cloud, begin-
ning a little beyond the base and extending a little beyond the stigmatical
branch. It does not touch the anterior nor the posterior margin of the wing
and is more distant from the latter than from the former.

Numerous specimens reared by Mr. Norton from the root-gull of the
rose produced by RhoiHtea ra<h'cum, O. S.

A series of specimens was also communicated to me \>y Mr. Nor-
ton, distinguished from the former by the following characters : —

1. Front green, usually with a golden yellnwish spot above the an-
tennje (but not purplish on the ncellar triangle). 2. Purplish spot on
the prothorax small, often almost indistinct. 3. Abdomen greenish at
the base (with hardly any trace of blue) ; more coppery than pur-
plish towards the tip. 4. Ilind coxre reddish coppery, especially their
hind part.

Mr. Norton's collection contained a considerable number (more thaa
50) specimens of C. maipiijlca, all labelled as having been reared
from the gall of Rhodifes radkum. There was, besides, about an
equal number of specimens not labelled and therefore of unknown ori-
gin. All the latter specimens differed from the former in the above
mentioned characters. If it was not for this perfect agreement of so
many specimens obtained, apparently, from the same source, I would
not hesitate to consider them as a mere variety of C. magnlfica. Even
now I am doubtful about their specific distinctness. Among ."\Ir.
Norton's specimens a single one, agreeing with the described variety,
except that the basis of the abdomen is blue, was marked as having
been reared from the gall of Rliodifex Jiirolor.

If C. mnij)n'fir(i infests rose galls of diflferent kinds, phytophacic va-
rieties may occur.

8. C. chrysochlora, n. sp. — Bright green, abdomen near the base somewhat
bluish, feet yellow; ovipositor longer than the abdomen but shorter than the
body. — ^ about 0.10, 9 0.14 — 0.15; ovipositor about 0.12 of an inch long. Some
females are much smaller and have the ovipositor proportionally shorter.

9. Ileail of a lighter green than the thorax or slightly golden green, always
more golden yellow or even reddish in the middle of the face. Mouth yellow-
ish brown. Antennre black, scapus yellow. Thorax green, often bluish, finely
pubescent, microscopically rugose and punctured with moderate density. Me-
thorax smooth, shining, with an almost imperceptible rugosity on the sides.
Abdomen green, bluish at the base, golden yellowish or somewhat coppery on
the underside towards the tip. The coxse green, j'ellow at the basis and, in
some specimens, on the inside; hind coxse green, moderately sculptured (not
more so than in C. magnijica), and, therefore, not opaque. Feet yellow, knees,
tips of the tibiie and tarsi paler; tip of the latter brown. Ovipositor longer

Several S and $ specimens reared from the gall of Jihodttes dichlo-
ccro^, Harris.

31 r. Norton's collection contained several males distinguished from
the preceding by the hind femora being green in the middle. They
may belong to the same species, as I do not perceive any other differ-
ence.

(t. C. solitaria, n. sp. — Pale green, abdomen with a brassy tinge, hind bor-
ders of the segments somewhat bluish-green; feet yellow; ovipositor as long or
longer than the body. — 9 ^'jout 0.12; ovipositor about 0.13 of an inch long.

9 ■ Head with golden reflections; thorax pale green. (If the green color of
C. chri/socldora may be compared to that of Cicindela higuttaia, Fab., the shade
of green of the present species is more like that of Chlcenius soUtarius, Say).
Abdomen green, with a yellowish, brassy, or somewhat coppery reflection, the
hind margins of the segments being bluish green. The description of the
sculpture of the preceding species can be applied to this. The scutellum is
more flattened, less convex than C. chrysochlora. Fore femora green, yellow at
the tip; hind femora green in the middle with a yellowish-brassy tinge,
green along the borders. Feet yellow, knees and tarsi pale. Wings hya-
line.

Three 9 specimens reared from a rose gall (either Jilioditcs radicnm

AMERICAN MYRIAPODA. 65

On some new and little known MYRIAPODA from the Southern AUeghenies.

BY E. I). COPE.

PETASERPES, Cope.
Head concealed to the bases of the antennae by the shield-like expan-
sion of the scutum of the first anuulus. Ocelli two, beneath the mar-
gin of the same, and at the approximated bases of the antennas. Latter
large, stout, hairy, six-jointed. Annula3 without lateral processes, each
with two pores, forming two rows on each side of the body.

Petaserpes rosalbus, Cope.

The sagments of the body are flattened below, and gently convex
above. Their lateral expansion is a little greater than the length of
the extended feet. Each has a delicate impressed line near the poste-
rior margin, which passes round the extremity, producing the semblance
of a longitudinal angle. The extremital margins are entirely continu-
ous. The transverse diameter contracts very rapidly at both extremi-
ties, and the anal annulus and head, are relatively exceedingly small.
The basilar segment is semidi.scoid, and forms the segment of a hollow
sphere. The anterior aspect is horizontal, and has a delicate marginal
rim. The head is inferior, and has the short conic form of Octorjiena,
Wood. The mouth is situated near the extremity of a cone, and not
of a rather flattened muzzle, as in the Andrognathidae; there are hairs
scattered about it and the sides of the head. The antennae are of re-
markable size for the head, and originate near together just at the in-
ferior margin of the basilar segment. Just within and above them at
their base is situated on, each side a short cresccntic ocellus or ag"^re-
gate of ocelli, whose superior extremity is concealed by the margin of
the basilar segment. In one specimen each of these presents a rugose
surface, and in another seems to be divided into four ocelli, perhaps by/
the accumulation of a light colored deposit between the elevations.
The antennae possess six joints, of which the antepenultimate are a
little the shortest. They become successively stouter towards tlie cx-
cxtremity of the antennae, and are all (juite hairy.

The reproiluctive organ of the male is a subglnbular body on a short
pedicel, hairy except the convex extremity, which is smooth. On the
inner side two short pedicels support, each, a short curved spiuC; one
curved backwards and another forwards.

The annuli are smooth. The anal annulus is small, and for the

THAN-S. AMER. EST. SOC. (9) MAY, 1870.

greater part ovcrroofed by the penultimate, which is broader than
usual. The legs are minutely hairy.

The color of this animal in life is a delicate rose color, whitish at one
extremity and shading into orange at the other.

The number of the annuli in the adults I find to be fifty-three down
to fifty-one. In specimens a little smaller there are forty-six and four,
and in the smallest and palest colored, hence younger, the number
ranges from forty-three to thirty-nine.

The locality whence I obtained this species is on the western slope
of the Cumberland mountains, in the northern part of East Tennessee.
I found them under masses of chestnut bark in two places, in small
families of some size, with Fol^desnuis. They have the motions
of Polydesmi, i. e. they progress slowly and roll themselves up when
captured.

This form is near Wood's Octoglena, of which one species, {0. hivir-
gatii) was found in northern Georgia. It differs generically in the
great extent of the basilar segment, which is very short and leaves the
head exposed in Octorjlena, and in the agglomeration of the ocelli,
which, in the latter, are arranged in two long series of four each.

The annuli appear to be completely chitinized on the median line
below.

Ohservafions on other Mi/riapoda.

The Bracliycijhe lecontei, Wood, occurs in Jeiferson County, in the
Valley of East Tennessee. It is not very common and lives under
bark of fallen logs. The structure of its head is much like that of
Andfognatlim externally, and the genus is probably to be referred to
the Andrognathidae rather than to the Siphonophorida). It differs
from the former genus in marked characters, the confluence of the
last three articulations of the antennae being the most important.

The Cambala annidata Say, (Cope, Proceed. Amer. Philos. Soc.
1869, p. 181,) is one of the most abundant of the Myriapoda in the
mountain regions of Tennessee and North Carolina. It is more abun-
dant than the Spirostrephon lactarius, which it considerably resembles,
and with which it is found under bark, etc.

As is known, the Myriapoda of the orders Strongylia and Sugentia,
are sluggish in their motions and not furnished with offensive weapons.
They therefore produce secretions of a very acrid character, which fur-
nish a secure defense against many enemies. The species of Spiroho-
lus and Jidus discharge a yellowish juice having much the smell of
aqua regia,and a very acrid taste. The Spirostrephon lactarius exudes

AMERICAN MYRIAPODA. G7

from a series of lateral pores* a fluid wliich has in its odor a close re-
semblance to creasote The Puli/desmns virglniensis is defended by a
fluiil which has almost exactly the smell of hydrocyanic acid, and is
fatal to small animals. Pctaserpes rosalbus secretes a considerable
quantity of a milky substance, which has the perfume of gum cam-
phor.

Pseudotremia cavernarum, Cope, is found :n some of the limestone
caves of the valley of Tennessee. I found it especially abundant in
the Lost Creek Cave on the Ilolston River, in Granger County, near
and on piles of bat excrement under stones. In company with it were
numerous small, leaping, lepismoid insects, a Pselaphid beetle, a Cara-
bid somewhat like Patrohus, and a spider. Large numbers of a very
small Ixodes-like animal covered parts of the surface and cavities of
the body of a dead bat in a locality distant from the mouth of the
cave.

The writer examined the Lost Creek Cave for a distance, stated to
have been measured, nearly two miles from the mouth, and the state-
ment is probably correct, judging by the time occupied in passing
through, to the point reached. A creek of considerable size issues
from the cave; near the mouth it is dammed, and a race leads the
water for a short distance to a corn mill on the banks of the Holston
river. The water is crossed by the path perhaps five times before it
fills up the passage so as to prevent further progress. The passage
is wide, dry, and with so few irregularities that a [lublic road might
be readily made in it to that point. I could not find any fishes; just
outside the mouth a small Uranidea is not uncommon. The dam with-
in the cave abounds in dead los, L^niones. etc., said to be carried there
by floods of the Ilolston, but quite as probably the refuse of the meals
of Lidians. Bones of Indians, turkeys, and game animals are to be
found at the mouth of the cave, which is in a bluff some fifty feet
above the level of the Kiver. xVt one side of the entrance a hard
limestone deposit contains charcoal, Uniones and ^Melaniaj. The lime-
stone cliff produced abundance oi Asplcnium montanum, Pellsea atro-
jmrpurea, and a delicate bipinnate Pteris.

Descriptions of two new species of MUTILLA from Mexico.

BY CHARLES A. BLAKE.

Mutilla Cressoni, n. sp. — Female. Head sub-quadrate, somewhat narrower
than the thorax, posterior angles rounded. Black, clothed with dense golden
pubescence. Antennre rufo-piceous, flagellutn clothed with scattered glittering
hairs. Eyes prominent, polished, rounded. Thorax sub-ovate, narrowed pos-
teriorly, and abruptly truncate, mesothorax with lateral carinse, disc black,
coarsely granulate, with a few scattered black hairs, and margined with dark
golden pubescence. Abdomen ovate, deeply punctured, basal segment black,
the apical margin fringed with pale pubescence, second segment with two ovate
fulvous spots at the basal margin, and a broad, anteriorly emarginate, band of
the same color near the apical margin, clothed with deep golden pubescence;
third and fourth segments black, with a longitudinal line of paler pubescence,
forming the black ground into two lateral quadrate spots; fifth and sixth seg-
ments clothed entirely with pale golden pubescence, apex black. Ventral seg-
ments fringed with pale golden hairs. Legs black, middle and posterior tibiae
armed with a row of spines, and clothed with long pale hairs. Entire insect
beneath clothed with long, pale, glittering hairs. Length 9 lines.

Ilah. — Mexico. Two specimens (Coll. Am. Eut. Soc. from Prof.
F. Siimichrast).

I take great pleasure in dedicating this beautiful species to my friend
and co-laborer in entomology, Mr. E. T. Cresson.

Mutilla Nortoni, n. sp. — Female. Head rounded, wider than the prothorax,
posterior angles more acute than in the preceding species, coarsely punctured,
clothed with short golden pubescence, interspersed with longer hairs. Anten-
nas black, naked. Eyes round, prominent, polished. Thorax black, narrowed
posteriorly, somewhat constricted, coarsely punctured, with a broad diseal
band clothed with appressed, bright golden pubescence, metathorax slightly
truncate, sides clothed with a dense silvery pile. Abdomen ovate, coarsely
punctured, basal segment clothed with pale golden pubescence; second segment
with four orange spots, clothed with a scattered golden pubescence, the two at
the basal margin, sub-triangular, those on the apical margin are larger and
nearly joined together, third and fourth segments black, fifth and sixth with
golden i)ubescence, apex black; ventral segments fringed with long pale hairs.
Legs black, middle and posterior tibise and tarsi clothed with silvery hairs,
those on the tarsi being longer and much more dense. Underside of thorax
and aljdomen clothed with obscure greyish hairs. Length 8 lines.

ILib. — Mexico. Two specimens (Coll. Am. Ent. Soc. from Prof.
F. Sumichrast).

Closely resembles J/. Cressoni', and is readily distinguished by the
band ou the thorax, and by the less robust form.

This fine species is respectfully dedicated to Mr. Edward Norton, of
Farmington, Conn., from whom I have received valuable assistance in
the study of this family.

CALOSOMA, Fabr.
C. Haydeni, n. sp.

Tlio above name is proposed f.)r a species in which tho first three
joints of the anterior tarsi of the mile are spoagy pubescent beneath,
the base of thorax truncate. It is therefore allied to our trUte and
obsoletum, but differing from them in having the elytra connate and
the body apterous. The head is large, as in triste, and the frontal
impressions deep, rather finely punctured and wrinkled ; vertex with
but few punctures, occiput smooth. Thorax as in frisfe, but with the
basal impression deeper and the lateral margins at base more strongly
reflesed, nearly as much as in semilaeve. Disc with distinct coriace-
ous sculpture and feeble median line, margins coarsely but distantly
punctured, becoming more dense near the hind angles and basal
region. Elytra elongate oval, humeri strongly rounded, and as dis-
tinctly margined as the sides. Surface very convex in both directions
and with striaj of fine distinct punctures feebly impressed. Basal
region with distant sub-muricate punctures. Margins distinctly mu-
ricately punctured, more dense at the humeral region, almost disap-
pearing at the apex. Metathoracic parapleurae and sides of abdomen
with coarse punctures. Its color above and beneath is shining black.
Length .84 inch; 22 mm.

Collected in Southern Colorado, by C Thomas, of the U. S. G-eolog.
Survey, under Dr. F. V. Ilayden.

This species must be referred to the same group with C polition,
(?haud., which I have had an opportunity of examining, through the
kindness of M. A. Sall6, of Paris, from which it differs (besides the
sculpture,) iu its greater general convexity, broader and more strongly
reflexed thoracic and elytral margins. In politum the basal thoracic
impressions are scarcely at all evident. In accordance with the ar-
rangement of our species published by Dr. Leconte, Proc. Acad, 1802,
p. 52, this species should be placed as a subdivision of group IV.
Both sexes are known to me, the female having slightly broader elytra.

C. tepidum, Lee.

Specimens collected by me at Sacramento, Cala., differ from the
Oregon type in being entirely black. The thoracic and elytral sculp-
ture is rougher, and in many specimens the large punctures usually
golden or bronzed, seen in the Oregon specimen.s, are here totally
obliterated.

This species has been redescribed as C. irregidare, by Mr. Walker,
Naturalist iu British Columbia, Lord, Vol. II., p. 312.

Callisthenes pimeliiodes, Walker, loc. c{t.=^Calosoma luxaium, Say, var. Zim-
■niermanni, Lee.

Very many specimens of the varieties of luxatiim forming a fine
series, are known to me. The form named by Walker is probably
that in which the tuberculiforra elevations of the elytra are more
prominent ; the variety bus been known to us for many years.

C. latipenne, n. sp.

Allied so liixatuni Say, but differs from all the races of that species
in having a proportionately smaller head, broader thorax with more
rounded sides and more broadly reflexed margin, apex less deeply
cmarginate, basal' angles more broadly rounded ; elytra more broadly
oval, marginal , groove deeper from the more strongly reflexed
margin.

Color black and shining, head sculptured as in the smooth forms o{ luxatitm ;
thorax moderately convex, disc smooth with the median line distinct, with
the sides coarsely punctured and wrinkled. Elytra broadly oval, smooth and
fshining, disc with approximate striiB of very fine punctures, margin
broad as compared with luxaium and equal in its entire length except at base
where it is narrower, rather densely muricately punctured and iu well pre-
served si:)ecimeus of a greenish bronze color. Under surface and legs black
itnd shining, almost entirely smooth and impuuctured. Length. 54 — .68 inch ;
14 — .17 mm.

In most of the specimens before me the margins of the elytra im-
mediately behind the humeri have three or four very distinct serra-
tions. This character is quite common in the species of the triste
group, but not seen in any of our species of the group Callisthenes.

On comparison the male of this species is found to be as broad as
the female of disco rs Lee, the elytral margin broader and the surface
sculpture of a different order.

Collected by Mr. Wm. M. Gabb and myself, in the elevated regions of
the South Sierras of California.

OMOPHRON, Latr.

Several new species of Omophron beiug in my cabinet, I have thought
it advisable to define our species by means of short descriptions,
so that the student may be enabled to determine them ; for although
our species are comparatively few in number, their descriptions are so
widely scattered as to be inaccessible to many.

Our species divide themselves into two groups:

Group I. — Species broadly oval, shining, elytral strins almost en-
tirely eflfaced at apex and indistinct at the sides median thoracic line
scarcely evident. Two species are known lahiatum and nitidum.

Group IT, — Species less broadly oval, less convex and shining,
elytral striD3 attaining (very nearly) the apex, latei'al strioo as dis-
tinct as the discal.

Elytra, 14 — striate.

Strite deep, finely and closely punctured gilae.

Strioe moderate, punctures rather distant and obliter-
ated at apex obliteratum, n. sp.

Stride faint, punctures large, distant robustum, n. sp.

Elytra 15-striate.
Broadly oval.

Punctures of elytral strire obliterated at apex dentatum.

Punctures distinct at apex.

Lateral margins only, of thorax, pale americanum.

Lateral, basal and apical margins pale tesselatum.

Elongate oval,

Elytral strife not deeply impressed, finely and closely

punctured ovale, n. sp.

0. labiatum, Fabr. (Scolytus) Syst. El. I. p. 248: Say (Omophron) Trans. Am.
Phil. Soc. vol. II, p. 79, 1S2S; Dej. Sp. 2. 261, 1S26.— Broadly oval, convex, shin-
ing; color dark brown or nearly black, lateral margin of thorax and elytra
pale, the latter broader at apex. Elytral strife moderately deep at their basal
third with rather large but distant punctures; as the strife approach the mid-
dle the punctures become effaced and near the apex the strife themselves are
totally obliterated, scarcely any trace remaining ; toward the sides the strife be-
come also effaced. The pale limb of the elytra in most specimens gradually
shades iuto the darker color of the disc, but little tendency being shown to the
formalinu of branches or processes as in all our other species. The under sur-
face is dark piceous witli the sides and apex of ab<lomen paler. Theprothorax
is nearly blackwith the lateral margins pale silvery-white, with coarse sparsely
placed punctures more closely approximated at the apical and basal regions.
Head black with a metallic lustre near the eyes, anterior margin of front and
clypeus brownish, labrura silvery-white. Length .24 inch; 6 mm.

Middle & Southern States.

0. nitidum, Lee. Am. Lye. IV, p. 347; niiens Chaud. Rev. Mag. Zool. 1S68, p. 7;
uot liitidmn Chaud. coll.

Our most broadly oval, convex and shininpj species. Differs from
hihiatum in having the striae of the elytra less impressed, the punc-
tures larger, more distant and extending fully two thirds the distance
from the base to the apex. The punctures forming the lateral striae
are also well defined. The color of the entire upper surface is metal-
lic green, the elytral pale border narrow, broader at the humeri ; from
this border slightly behind the humeri a small process enters, at right
angles to the border, to the eighth stria and becomes gradually nar-
rower to the apex; behind the middle another process extending;
obliquely forward to the sixth stria gradually narrowing and with
sinuous margins ; near the apex a subquadrate process parallel with
the suture but separated from it by the first interval, and with its
tips emarginate. Thorax similar to lablatum, pale margin impunc-
tured, basal and apical regions coarsely but not densely punctured.
Head metallic green, coarsely and very sparsely punctured, with the
frontal spot and clypeus pal--,; labrum silvery-white. Under surftice
somewhat paler than lahiatum. Length, .20 — .24 inch ; 5 — 6 mm.

Occurs in Illinois, Kansas, Indian Territory and Texas.

The synonyms have been suggested to me by Dr. Leconte in a late
letter from Paris, where he had an opportunity of inspecting that por-
tion of the cabinet of Chaudoir containing Oniophron. He also states
that 0. nitidumX Chaud. (cabinet) is still undeseribed and is from
Louisiana.

0. gilae, Lee. Ann. Lye. Y. p, 201.

The characters given in the preceding table render any detailed de-
scription unnecessary. The prevailing color of the upper surface is
pale yellowish. Head coarsely and sparsely punctured between the
eyes; vertex somewhat darker. Thorax very coarsely but sparsely
punctured over its entire surface, with the median line distinctly im-
pressed, and with a transverse greenish metallic spot equalling in
length about half the width, and in its width about half the length of
the thorax. The elytra have on each side of the scutellar region a short
greenish space extending along the basal margins sending three short
processes backward, the first on the interspaces 7 — 8, second on inter-
space 10, third on interspace 12. The space between the suture and first
stria is dark and near the apex expands into a small rhomboidal spot.
From the suture outward on each side, at the anterior third a triangular
dark spot, apex at suture, base at stria 6; between the latter spot and the
margin a small subijuadrate spot between striae 8 — 12; at the posterior

AMERICAN COLEOrTERA. 73

third are two spots similar to the last, the first between striaj 3 — 6 the
second between striaj 9 — 13, these are united by a narrow band arching
forwards. The under surface is pale brownish with the sides and apes
of abdomen paler. Leneth .28 inch; 7 mm.
From the margins of the Gila River, Arizona.

0. robustum, n. sp.

Similar in form to the preceding species but rather more convex,
robust and shining. The length of the elytra as compared with the
breadth is shorter than any other of our species. The thorax is com-
paratively shorter than in gilx, the punctures coarse but with the
marginal and the dark discal space almost free from punctures. Head
with but few punctures, front pale yellowish, vertical and post ocular
regions and a narrow line above the eyes brownish ; clypeus pale ;
labrum silvery-white. The thorax has a narrow transverse band of
metallic green color slightly extending forwards and backwards on the
median impressed line and an oval brownish spot on each side between
the metallic band and the margin. The elytral sculpture consists of
striae of rather coarse punctures distantly placed, the striae themselves
very feebly imprcs.sed. The ornamentation is similar to that seen in
gilse, but the narrow black basal line is absent as also the dark sutural
line between the scutellar region and the position of the second row.
and also that posterior to the third row of spots. The color of the un-
der surface is similar to gilse. The specimen is perfectly mature.
Length .26 inch ; 6.5 mm.

A single specimen in the Cabinet of Dr. Leeonte from the Nuva
Scotia region.

This species at first glance might be mistaken for (csselatum but the
latter has fifteen rather deeply impressed, closely and rather fiii.'lv
punctured striae.

0. obliteratum, n. sp.

This species also has but fourteen elytral stria), but with a close
resemblance to amerkanum. The thorax is longer and rather more
narrow in front. Head similar in color and sculpture. Thorax with
the entire surface, even to the margins coarsely and sparsely punctured,
less densely on the disc, median line feebly impressed ; pale margins
narrow and extending inwards by a rather broad bond, a short distance
along the apical margin. The elytral coloration is almost identical
with anicrit atium, but the punctures of the striiv; which extent! very
distinctly to near the apex in the latter species are almost entirely ob-
literated in this and the stria) are also much fainter. Under surface

piccous; abdo)nen, especially at the sides and tip, paler. In this
species, as iu americanum, the dark spaces of the elytra are but fiiintly
tinged with metallic green. Length .27 inch ; 7 mm.

A single specimen collected at Camp Grant on the San Pedro
River, a tributary of the Gila, Arizona.

0. dentatum, Lee. Ann. Lye. V, p. 200.

Resembles fjilse in form and markings. The thorax is however
longer and with the pale margin and a discal transverse space scarcely
punctured, and the median line more feebly impressed. The metallic
discal transverse band is longer and approaches more nearly the mar-
gin. From the other species of the group it differs by having the
punctures of the strige at the apical third of the elytra almost entirely
obliterated. Length .28 inch ; 7 mm.

Occurs on the banks of the Gila in Arizona, Fort Yuma, Teraecula,
Posey Flat, Owen's Valley, and other regions bordering the Colorado
Desert of California.

0. americanum, Dej. Sp. 5, p. .583 ; Sayi Kirby, Fauna Bor. Am. IV, p. 65.

This species is so widely distributed as to need no description. The
elytral interspaces are here more convex than in any other of our
species, the punctures of the stride rather fine and approximated and
distinctly visible almost to the apex. The median thoracic line is
faint. The disc of the thorax is dark brownish, slightly tinged with
metallic green. The lateral margins pale, narrow, suddenly dilated
at apical end, and with a narrow extension along the base, for a short
distance. Length .24 — 28 inch ; 6 — 7 mm.

Occurs in Canada, New England, Middle and Western States.

0. tesselatum,Say. Journ. AeacL III, p. 52 ; Lecontei Dej. Spec. V, p, 5S2.
Resembles r/Ux and dentatum by the elytral ornamentation. The
striae are very distinct at apex and the punctures closely placed in the
discal region are more distant near the apex, but still quite strongly
impressed. The dark rhomboidal spot formed by the dilatation of the
dark sutural line, seen in the two species above mentioned, is here
absent. The thorax coarsely but sparsely punctured, the discal space
and the lateral marginal region with but few punctures. The median
line is moderately impressed. The discal metallic spot is short equal-
ling about one-third the width of the thorax and with narrow processes
extending to the basal anxi apical margins along the median line.
Under surface ferruginous, margins and apex of abdomen paler.
Length .26 inch; 6.5 mm.
Canada and Middle States.

AMERICAN COLEOrTERA. 75

0. ovale, n. s]\ — Elongate oval, sides of thorax JubpTrallel behind the middle.
Elytra oval, finely 15 striate, punctures small rather close, interspaces flat. Head
above the eyes sparsely punctured, vertex shining metallic green, margin of
front along the suture, clypeus and labrum pale. Thorax coarsely punctured
over its entire surface, more densely near the base and ajiex, median line moder-
ately impressed; with a transverse nearly black faintly bronzed band extend-
ing nearly to the lateral margin and broadly along the median line to base and
apex; the pale spaces therefore consist of a subquadrate spot at each angle
united by a narrow line along the lateral margin. Elytral disc brownish
black with feeble lustre and scarcely at all bronzed; margin pale with three
processes on each side extending inwards, the first behind the humerus broadly
triangular extending to the 11th stria, the second behind the middle, narrower
and with irregular borders extending slightly obliquely forward to the 10th
stria, the sub-apical process is sub-quadrate, parallel with the suture and
emarginate at its inner and front sides; in addition a small, badly defined ob-
lique spot on each side near the scutellar region, a rhomboidal spot near the
apex of the first lateral process and an irregular feebly sinuous band near apex
of the second process and extending toward the suture. Scarcely any metal-
lic lustre is seen exr/epting at the basal region and along the anterior third of
the suture. Under surface ferruginous brown, apex of abdomen paler. Length
.26 inch; 6.5 mm.

Kasily koowa from any other of our species by its more elongate
form, finely striate elytra witli flat interspaces. In one specimen be-
fore me the thorax is subparallel behind the middle, the other has
the sides distinctly divergent to the base.

Two specimens, 9 % , Fort Crook, California.

In glancing over our species, two forms of elytral marking are seen.
In one. group the dark or metallic spaces resolve themselves into three
transverse rows of spots, basal, submedian, and sub-apical. The njar-
gins are pale and the darker spots occupy much less space than the
pale portions. In the second group the margin alone is pale with
three branches extending inwards, invading for a very short distance
the darker color of the disc; an occasional pale spot may bo found in
the dark discal space. In accordance with the extent of the dark
iliscal .space, our species may be arranged as follows;

1. labia fum ; 4. ohlitcratum ; 5. amcricamnn;
2. nif Ilium ; 3. ovale;
while those in which the pale colors prevail ;

1. rohiistam ; 3. dentatum ;

2. (jikn ; 4. tesselatum ;

the first being the paler, while the groops approach each other
through aniericanum and fesseldfnm. The species all vary
somewhat in the extent of their markings and the preceding remarks
apply only to a general view of several specimens of each.

76 GEORGE II. HORN, M. D.

PSEUDOMORPHA, Kirby.
P. Behrensi, n. sp. — Oblong parallel, moderately depresserl, piceous black,
shining. HeaJ smooth, with but few distant punctures each bearing an erect
yellow hair. Thorax moderately convex, nearly twice as broad as long, apex
feebly eraarginate, angles obtuse, sides strongly rounded, slightly converging to
apex, hind angles broadly rounded, base truncate ; sparsely muricately punc-
tured, each puncture with an erect hair, margin slightly reflexed and sparsely
fuubriate. Elytra parallel, nearly twice longer than broad, feebly convex,
sparsely muricately punctured, each puncture with a yellowish erect hair,
margin sparsely fimbriate with yellow hairs. Body beneath ferruginous
brown, abdomen punctured and pilose. Legs ferruginous, femora very robust.
Length .38 inch ; 9.5 ram.

This species differs from Cronkhitet, Horn, in having the form more
parallel and more convex. The thorax is much more convex and not
as broad and the sides are mare broadly rounded and converge less to
the apex ; the lateral margin is more broadly reflexed and the inj-
pression within, consequently deeper and extending faintly within the
hind angles. In this species the disc of thorax has a median faintly
elevated ridge which is scarcely at all evident in Cronkhitei The
elytra of ^e/i/'CJisi are parallel on the sides while, in Cronkhitei they eon-
verge toward the apex, in the latter species the elytra are nearly
smooth with scarcely any traces of punctures, in the latter species the
muricate punctures arc quite strong and though confusedly arranged at
base are in strias beyond the middle. The femora of B Jirensi are
much more robust than those of the other species.

For this interesting addition to the fauna of California, science is
indebted to Mr. James Behrens of San Francisco, by whom a single
specimen was collected and kindly placed at my disposal. I am not
inf irmed of the precise locality from which it was obtained. It must
however belong to the fauna west of the Sierras.

BYRRHUS, Linn.
B. Pettiti, n. sp. — Oblong oval, similar in form to geminaius Lee. Sides of tho-
rax nearly straight surface clothed with silvery hairs, with the sides, median line,
anterior apical angles and basal spot on each side black. Elytra densely
clothed with brownish black hair, with short velvety lines irregularly disi>o3ed,
and a cresccntic band convex backwards clothed with silvery liairs. Body
beneath rather coarsely punctured and sparsely cinoreo-i)ube3ceut. Scutellum
black. Length .34 inch ; 8.5 mm.

The form of the species is similar to (jeminatuH Lee., but rather less
convex. The larger portion of the thorax is clothed with silvery
pubescence with a slight yellowish tinge, with black spaces arranged
ill the following manner; a median black line aometimos divided sn as
to form an apical triangular and basal linear spot; at apex a small tri-
angular black spot joining the black margin which is not seen when

AMERICAN COLEOPTERA. 77

viewed directly from above; a basal triangular black spot on each
side equally distant from scutellum and angles, larger than the apical
s-pot but not joining the margin. The scutellum is velvety black.
The elytra are cliithed with brownish black hair with short lines of
velvety black rather irregularly placed. At the middle of the elytra
and common to both is a moderately wide crescentic band (of which
the ends are obtuse) with the concavity forwards ; extending three
fourths of the width of each elytron, and clothed with silvery white
hairs. Body beneath densely punctured and sparsely clothed with
short cinereous hairs.

This species appears to be rare in Canada West. For two fine
specimens in my cabinet I am indebted to Mr. Johnson Pcttit, of
Grimsby, Ontario, to whom I take pleasure in dedicating it, as an
evidence of appreciation of the services he has rendered science in the
investigation of the fauna of his neighborhood.

Lichnanthe Edwardsi, n. sp. — Body black, head and thorax greenish metal-
lic, elytra pale brownish testaceous. Head densely and coarsely punctured,
Thorax as broad as long, sides rounded in front, sub-parallel behind, base
rounded, disc densely and coarsely punctured except at the hind angles, and
rather densely clothed with long black-bi'own hairs. Elytra longer than their
conjoined breadth, brownish testaceous, rather coarsely and densely punctured,
and sparsely clothed with short black recumbent hairs. Body beneath black,
faintly metallic and sparsely clothed with hairs. Abdomen more shining very
finely punctured and with fewer hairs ; the last two segments are brownish
ferruginous. Legs black, femora and tibise hairy. Length .62 inch ; 15.5 mm.

The elytra are contiguous along the anterior three-fifths of the
suture then strongly divergent. It may be known from all our spe-
cies by the hair of the thorax being long and black, the hair of the
under surface is somewhat paler and very much less dense. The last
joint of the maxillary palpi is very distinctly excavated as in Dasj/dera,
and by the increase of the number of species the diflferences between
it and Lichnanthe appear to be vanishing.

For the unique in my cabinet, I acknowledge great indebtedness to
Mr. Henry Edwards, of San Francisco, to whom I take pleasure in
dedicating it. Occurs in '• Oregon" without more specific designation
of locality.

Serica elongatula, n. sp. — Castancous, or testaceous, brown, elongate oval ;
^ides parallel; sub-opaque, faintly sericeous. Head rather densely punctured
in front, sparsely on the vertex, clypeus faintly emarginate, angles broadly
rounded, margin rcflexed. Thorax convex, neither coarsely nor sparselj' punc-
tured, rather mofe than twice broader than long, sides strongly rounded and
fimbriate with long hairs. Elytra elongate sub-parallel, fimbriate on the m.^ir-
gin, very convex transversely, faintly striate and with punctures irregularly

placed. Beneath very sparsely punctured, elothed with long yellow hairs
sparsely placed, longer and more numerous on the pectus than abdomen. Length
.30— .32 inch; 7.5—8 mm.

Diflfers from all our species by its more elongate form, parallel sides,
more transversely convex thoras and elytra. The surface is very
fiiiutly sericeous.

Occurs rather abundantly in Owen's Valley California.

Dynastes Tityus, (Linn).

A specimen in my cabinet from Fort Grant, Arizona, has the
thoracic horn very nearly twice as long as in our eastern specimens,
the tip is broader and deeply emargiuate, and the two small horns
usually seen below the base of the larger are here reduced to small
tubercles and are placed on the base of the horn itself. The frontal
horn is also proportionately longer, distinctly grooved on its upper
edge and with a tooth about one fourth from the tip limiting the
groove in front. From the base of thorax to tip of thoracic horn the
length is 1.30 inch, in our eastern form a similar measurement gives
.86 inch. The specimens have otherwise .similar size and appear-
ance. For this variety the name of Di/nastes Grantu is pro-
posed.

Valgus californicus, n. sp. — Piceous-black, head coarsely punctured, vertex
moderately concave. Thorax longer than broad, coarsely but sparsely punc-
tured, with a broad shallow impression on the median line near the apex and
a moderately deep impression near the middle of the lateral margin. Disc of
elytra flat with moderately deep strise with convex intervals, irregularly dis-
posed. Pygidium oblique, moderately convex and styliferous at apex. Under
surface rather shining and coarsely punctured. Length .35 inch; 9 mm.

This specimen is in rather imperfect condition, being almost entirely
deprived of vestiture the few scaly hairs that remain being black. It
diflfers from either of our spacies ia the absence of any denticulation of
the sides of the thorax in front; the median sulcus is very faint and
the lateral impressions deep so that the sides appear to be slightly em-
argiuate when viewed from above. The entire surface although de-
prived of vestiture is feebly shining; the last two dorsal segments of the
abdomen have more lustre and are rather densely punctured. The
teeth of the anterior tibiae are short, the apical and third alone being
at all acute. The style (tariere) is short, flattened and rounded at tip.
A single specimen was found at Fort Crook, Cal., during July,
caught in a spider's web.

AMERICAN COLEOPTERA. 7!l

ACMSODERA, Esch.

A. quadrivittata, n. sp.

^Similar in form to A. tiihidus and agrees with that species in the
absence of any transverse carina and marginal groove to the last abdo-
minal segment, differing in the following particular : —

Thorax slightly more elongate, median sulcus more distinct. Elytra striat*',
striae coarsely punctured, intervals flat or feebly convex, and with a single
row of fine punctures, each bearing a very short yellowish hair; color piceous,
with two yellow strijjcs on each elytron, the inner occupying the third, fourth
and fifth intervals, the outer the ninth and tenth, the two stripes united at
apex. Body beneath black, with a slight greenish tinge, sparsely punctured,
each puncture bearing a short pale hair. Length .22 inch ; 5.5 mm.

One specimen collected in Utah by Dr. Palmer, placed at my dis-
posal by Mr. Townend Glover.

CORYMBITES, Latr.
C. longicornis, n. sp. — Form slender, elongate. Head piceous, coarsely
punctured; antennae ^ equalling four-fifths the length of body. Thorax moder-
ately convex, piceous, shining, coarsely not very densely punctured, more
densely at the hind angles ; form elongate, nearly twice as broad as long, sides
straight, slightly converging in front, hind angles slightly divergent, sub-
acute and tipped with yellow. Elytra elongate, slightly narrower behind,
moderately convex and shining, brownish, with broad discal yellow stripe ;
surface moderately striate, striae punctured, intervals moderately convex,
punctured and more rugose at scutellar region. Body beneath piceous, abdo-
men and legs paler. Entire surface very sparsely clothed with greyish hairs,
rather dense beneath. Length .54 inch ; 13.5 mm.

Allied to C. hivlttatus, Mels., differing in the much less dens!e!y
puuctured and more shining thorax, and the less acute and less diver-
gent hind angles. The antennae are also much longer.

For the unique in my cabinet I am indebted to Mr. Townend
Glover, of Washington. Collected by Dr. Parry in the mountains of
North Carolina.

COLLOPS, Erichs.

Uur species of C'oUops have become quite numerous and it has been
thought useful to present to the American students the results of a
short study of our species, and without desiring to prolong the present
paper unnecessarily, neither bibliography or description of each species
will be given except when found necessary to carry out the object of
the present sketch which is to present a table by which our species
may be readily determined without recourse to the various publications
in which they are now scattered.

In examining the antennae of our largest species (valuhis) there
will be found a curious articulated appendage arising from near the

80 GEORGE H. HORN, M. D.

baise of the second (really the third) joint of the antennoe, and extend-
ing forward, usually concealed in the deep cavity on
the upper surface of the joint. This appendage re-
'senibles an elongate inner maxillary lobe, is slender
and furnished at tip with a brush of stiff curved
hairs. "When this appendage is raised so as to be-
come d'stinctly visible the entire joint resembles somewhat the large
mandible of a crustacean. All the species exhibit this appendage
varyin"- in size and development according to the species. I find no
mention of this in any authors who have written on this subject. Its
use is probably for grasping the antennae of the female in copulation.
In capturing these insects during the act, I have found the male hold-
ino- the female rather tightly by the antennae, but without any exam-
ination inferred that this was done rather by the bending of the outer
joints backward upon the second.

Our species may be arranged in the following manner :
Elytra unicolorous.
Thorax yellow or reddish -yellow, iramaculate.

Elytra very densely punctured ; abdomen rufous. .tricolor (Say).
Elytra less densely but more coarsely punctured ;

abdomen black punotatus, Lee.

Thorax with discal black spot of greater or less ex-
tent; sometimes entirely black.
Elytra finely and densely punctured, surface
more densely pubescent. •

C tricolor and punctatns resemble each otlier very closely. The
characters given in the table being the'only ones in which they differ.
In color the head is nearly black ; thorax rufous immaculate ; elytra
aeneous or bluish black. Two specimens before me of tricolor have
a short narrow space at the middle of the lateral margin of the elytra,
rufous. The former spaces is widely diffused, occurring from Canada
and the Middle States to Kansas, the latter is from Kansas. Addi-
tional collections may show them to be identical.

C. cximius and niyriceps resemble each other, differing scarcely as
much as the two preceding species. Their colors are similar to the
above species, the thorax having in addition a discal black spot vary-
ing from a longitudinal broad band to a size covering all but a narrow
margin. Occurs in the Middle and upper Southern States.

C. marginicolUs is larger than eximius, the anterior margin of the
front not rufous, thorax with only a narrow pale margin, and the ely-
tra much more densely punctured and opaque. Occurs in California.

C. cribrosus is a somewhat variable species. The typical and most
abundant form has the thorax almost entirely black with a very nar-
row rufous margin reduced at times to a narrow space at each angle.
The elytra are aeneous black or nearly blue and unicolorous rather
coarsely and densely punctured. Specimens occur with the anterior
legs and middle femora fuscous and others with the legs entirely
black. In several specimens from Owen's Valley, a narrow, short
space at the lateral margin and a similar space at the middle third of
the elytra, are rufous. Specimens with well developed wings have the
humeri more distinct, several specimens without wings have thejely-
tra nearly oval. These cannot be properly separated as the transition
is gradual from those in which well developed wings occur through
others with imperfect wings to those with none at all. This species
occurs along the sea coast of California. The better developed arc

82 GEORGE H. HORN, M. D.

those from the salt marshes of Owen's Valley, a region which has in
many instances shown itself to be more closely allied in its fauna to
San Diego than the circumjacent desert regions.

C. hipunctatus is a large species similar in its coloration to tricolor.
There are on the disc of the thorax two small elongate black spots placed
obliquely like the pale spots of the thorax of Hippodamia convergent,
but diverging toward the base. In our series of this species may be
found specimens varying in a manner similar to that between tricolor
zndi punctatus and between eximius and nigriceps, that is, while many
specimens have dusky abdomen and legs almost entirely black others
again have the anterior and sometimes the middle legs rufous and the
abdomen pale. Occurs from Kansas to Arizona.

C marginicoUis must be associated with nigriceps and eximius. The
discal black spot is very large having but a narrow pale line which ex-
tends around the entire margin. As compared with either of the
above mentioned species the thorax will be found more transverse but
less rounded on the sides. The anterior legs and middle femora are
rufous. C. cribrosus has a narrower thorax than either of those men-
tioned. Occurs at San Diego, Cal.

C. validus, n. sp. — Head in front of the eyes pale rufous, vertex and occiput
blacli, finely and sparsely punctured. Thorax rufous with a black spot on each
side of middle; twice broader than long, sides moderately rounded, broader be-
hind the middle; surface smooth, shining with but few fine distant punctures.
Elytra robust, pale rufous with a basal blue spot on each attaining the epipleura
at humerus, narrowly separated at the suture, and a sub-apical larger spot
equally distant from suture and apex but nearer the lateral margin ; surface
densely punctured. Body beneath, legs and antennae pale rufous ; meso-, meta-
sternal and gular regions black. The entire surface of the body is sparsely
clothed with cinereous hair and the upper surface with few erect short black
hairs. Length .30 inch ; 7.5 mm.

A large species with head and thorax resembling hipunctatus aud
elytra marked as in quadrimaculatus.

This species is rather larger in size and more robust than any at
present known to me. It may be known at once from any of our
four-maculate species by the pale legs and thoracic spots.

A very few specimens were collected by Dr. Palmer near the
mouth of Yaqui River, Sonora.

C. quadrimaculatus and histrio resemble each other very closely,
having exactly similar colors. The thorax of the former is smooth
and shining, the latter sub-opaque, densely and very finely punctured.
The former species is widely distributed, a single specimen of the

AMERICAN COLEOPTERA. S3

latter from Lower California is known to me in which however the
apical spot does not attain the lateral margin.

C. pulchellus, n. sp.

This name is suggested for a form resembling quadrimacnlafun.
but diifers in having the abdomen entirely, antennae and legs (except
the tibiaj) pale red ; the tibiae are pale fuscous. The rufous color of
the body is much brighter than in any specimens of quad rimacula tun,
and the form rather more slender. Length .18 — .20 inch; 4.5 —
5 mm.

Occurs at Camp Grant, Arizona, during February.

0. halteatus is a large species with the blue patches on the elyti'aso
large that the elytra may be said to be blue with a narrow sutural mar-
gin and transverse narrow band at anterior third rufous. The elytra
are punctured as in quadrimacMlatns and by this character may be
known from C. insuhitm which is smaller and with a greater extent of
the surface of the elytra rufous.

C. limbellus, Gemminger, Col. Heft. VI, 1870; limbatics \\ Lee. l^ew Species,
1865, p. 94.

This species is easily known by having the thorax rufous and im-
maculate and the elytra entirely bluish except a very narrow entire
limb and a narrow sutural stripe. This species forms the link between
those species with no pale limb and those in which the blue forms
a broad vitta and by these latter to the four maculate species.

Occurs in Colorado and Nebraska.

C, laticoUis, n. sp. — Head entirely black, very finel}' and sparsely punctured
with sparse cinereous pubescence and erect black hairs. Thorax entirely ru-
fous, twice broader than long, disc smooth, sides finely and moderately densely
punctured. Elytra densely punctured, blue vitta narrowed at its anterior third.
Body beneath black. Abdomen rufous. Anterior and bases of middle femora
pale brownish, tibiae and hind femora nearly black. Length .22 inch ; 5.5 mm.

The entire upper surface is similarly clothed with pubescence as has
been described on the head.

Occurs at Cape San Lucas, Lower California.

C. conjluens differs from the above in being smaller, the blue elytral
vitta almost interrupted and above all by the sides of the thorax in
front being nearly straight so that the widest part of the thorax is
behind the middle. The .species above described having the thorax re-
latively broader and regularly rounded on the sides.

Occurs in Kansas.

C. vittatus and marginellus differ in having the elytra of the latter
much less distinctly punctured while the black thoracic spot is large

84 GEORGE H. HORN, M. D.

leaving ouly a very narrow rufous margin. In viftafus the thoracic
spot is usually small, occasionally as large as in margliieUus and some-
times entirely wanting in which case the species appears to be more
naturally associated with the preceding group. In any genus, where
species are distinguished principally by colors, variations from a type
must be expected and when such occur must be left for the determina-
tion of each student, as short reviews like the present cannot at all
times be a guide.

The former species is eastern, while the latter, occurs only in Cali-
fornia.

TROPHIMTJS, n. gen.
Head elongate, eyes rather distant from prothoras, epistoma mem-
branous; antennee slender, third joint slightly longer than the .second and
equal to fourth; maxillary palpi with last joint attenuate, longer than
the second, third joint very short. Anterior tarsi of male four-
jointed, five-jointed in female. Segments of abdomen membranous at
middle; tarsi with first joint very slightly longer than the second.
The above characters will serve to distinguish the genus from any
in our fauna. It is allied to the European genera TrngJopa and Ho-
vi'xodlpnus in which the maxillary palpi are alike in both sexes ; but
difi"ering from either in having the last joint longer than the second

AMERICAN COLEOPTERA. 85

and gradually attenuate toward the tip. Allied also to Ccphalagonia
Wollastou, Journ. of Entomol. 1. 442, differs in the form of the head,
and last joint of palpi. The third joint of antennae is not as long as
the fourth in Ccphalagonia and the first tarsal joint long.

The occurence of genera allied to the above might have been expected
from previous experience in the distribution of genera on the two
continents. A leg of Trophimus % mounted in Canada balsam shows
but four joints to the anterior tarsi even under high powers of the
compound microscope.

T. aeneipennis, n. sp. — Black, shining. Head elongate oval, one half longer
than broad, black, shining, imjDunctured; vertex slightly depressed. Antennae
black, basal joint paler. Thorax sub-orbicular, slightly truncate in front, rufous,
with a black spot at anterior margin, smooth, shining, moderately convex.
Elytra slightly broader at base than thorax and slightly broader toward apex,
humeri distinct, surface alutaceous, black with aeneous lustre. Body beneath
black, shining, meso- and metathorax with few short cinereous hairs, legs black,
sparsely cinereous pubescent. Length .12 — .14 inch; 3 — 3.5 mm.

Resembles AntJiocomus in appearance with the head nearly as long
as in Tanaops longiccps, Lee. The thorax is rufous except a small
black oval spot touching the apical margin.

From Colorado and New 3Iexico. For the opportunity of examin-
ing specimens I am indebted to Dr. Samuel Lewis of Philadelphia.

Attains nigripes, n. sp.— Body black, shining. Head black with slight
ssneous tinge, front broadly impressed with but few fine punctures and sparsely
clothed with cinereous hairs. Thorax rufous, one half broader than long, slightly
narrowed behind, sides strongly, base moderately rounded ajjex sub-truncate ;
surface shining, sparsely finely punctured and with few yellowish hairs. Ely-
tra scarcely wider at base than thorax, black with aeneous tinge, shining, indis-
tinctly alutaceous, and sparsely clothed with cinereous hair. Body beneath
and legs black, sparsely cinereo-pubescent. Anteunse black, with joints 2 and 3
testaceous. Length .08 — .10 inch; 2 — 2.5 mm.

The anterior tarsi of male have the second joint prolonged over and
partly covering the third, those of the female being simple. The api-
ces of the elytra are slightly less rounded in the male. The thorax
usually rufous has in some specimens a small longitudinal black spot
nearer the apex. The abdomen has a narrow membranous space at
middle.

Specimens from the cabinet of Dr. Samuel Lewis. Collected in
Colorado.

The genera allied to Attains and AntJiocomus appear not to be ex-
actly parallel in authors. The Anthocomiis of Erichson containeti
many elements now considered as belonging to Attains. Duval re-
stricts the latter name to those species in which, as in the above, the

TUAXS. AMEK. EST. SOC. (12) JUNE, 1870.

86 GEORGE H. HORN, M. D.

anterior male tarsi have all the joints in line but the second having a
process above which partly covers the third. Ehseus contains those
in which the anterior tarsi of male have the joints 3 — 4 — 5 placed
slightly obliquely to the first two while the second has a prolongation
extending obliquely inwards and not covering the third joint at all.
The characters drawn from the extent of membranous surface of epis-
toma or abdomen as noticed by Duval are not at all to be relied on in
the separation of genera. Should future study of our species prove
the correctness of the above views of Duval, Acletus, Lee, must be
suppressed as not distict from Ebsens. While the Ebmus of Leconte
is not that of Erichson who says, "Tarsi autici maris 5 articulati, ar'i-
culu senindo ohliquo." In the greater number of species of EhffM"^^
Lee, the anterior tarsi are simple in both sexes and not perceptibly
differing. They are therefore more closely allied to Anthocom,usyiih\c\\
indeed they resemble. The males however differ in having the apices
of elytra pale, prolonged and appendiculate. The. discovery of other
characters will probably necessitate the creation of a new genus for
these species. E. wt»rM^«s, Lee, is a true Attains. 'The species of
the latter genus are partially correct, some being Ebsens. In the pre-
sent paper the name Attains will be used for those species in which the
^second joint of anterior tarsus of male is prolonged over the third, con-
cave beneath, and not oblique. Ebseics will therefore contain those in
which the second joint is prolonged obliquely inwards and forwards so
that the joint when viewed from beneath and on its outer side is
very small and in the opposite directions large.

A. elegans, n. sp. — Head oval, shining, rufous, occupital region black.
Thorax rufous, sub-orbicular, not broader than long, moderately convex, shin-
ing impunetured, less rounded at apex than at sides or base. Elytra paler
rufous, alutaceous, sparsely punctured at sides, with a narrow basal black band
at base not attaining the humeri and an oval black near the apex. Body be-
neath pale rufous, meso and metasternum shining black. Legs ferruginous ex-
cej^t apices of anterior and middle, and the entire posterior femora black.
Abdomen in great part membranous. Antennae black, three basal joints rufous.
]\Iale with second joint of anterior tarsi prolonged over third, apices of elytra
feebly impressed. Length .16 inch; 4 mm.

Specimens collected at Keyesville, California, in the high Sierras
on flowers of iEsculus.

Abundantly different from all our species in the colors and form of
thorax, and recalls in its form species of Gnathium, the head and
thorax very nearly equalling the length of elytra which are but slightly
broader than the thorax. The elytra have few moderate punctures
near the sides. The entire surface is very sparsely clothed with

AMERICAN COLEOPTERA. 87

cinereous pubescence, the elytra having in addition sparsely placed,
short, black, erect hairs.

Malachius (Hapalorhinus) biguttulus, n. sp. — Body black with strong fene-
ous or bluish tinge. Head moderately broad, shining, sparsely punctured,
aeneous. Thorax broader than long, moderately convex, shining, very sparsely
and finely punctured: sides strongly rounded, margin moderately reflexed at
base. Elytra slightly broader than thorax, -seneous, moderately shining, scab-
rous, and with a yellow spot on each at suture near apex. Body beneath seneous
black. Male antennae serrate, black ; apex of elytra slightly impressed and
sinuous at margin. Length .14 inch ; 3.i mm.

The entire surface of body is sparsely clothed with cinereous pubes-
cence, that of the elytra being longer and more nearly erect.

A single specimen from Fort Tejon, Cal., and may easily be distin-
guished from any of our species o^ Malachius of the group Hapalor-
hinus by the characters above given.

CHAEIESSA, Perty.

C. elegans, n. sp.

Similar in form to C. pilosa (Forst.), Lee., but broaderaud differing
as follows :

Subopaque, pale red, elytra bluish black. Head coarsely punctured and
with semi-erect hairs; antennae black with basal joint onl^' red. Thorax
broader than long, truncate in front sides strongly rounded and slightly narrower
behind, base broadly rounded, with margin reflexed and black ; surface densely
and coarsely punctured and clothed with sub-erect hairs. Scutellum and
elytra bluish-black, the latter coarsely and densely punctured and scabrous,
the punctures coarse and less dense at the scutellar region, and with the
humeral region somewhat smoother, surface sparsely clothed with short, black,
sub-erect hairs. Body beneath and legs entirely pale red, and clothed with
pale sanguineous pubescence; tarsi, maxillary palpi and tip of mandibles black.
Length .46 inch; 1L5 mm.

The only species with which this might be confounded at first sight
is C. dichroa, Lee, from which it differs in having the thorax densely
pnnctured, the elytra more densely punctured and not submctallic and
by the legs being entirely red. The basal margin of the thorax is
more distinctly reflexed than any other of our species and the reflexed
portion margined with black. The hairs clothing the head, thorax,
under surface and legs are pale sanguineous being of a different shade
of color from the surface on which they are placed.

From San Joaquin County, California. A single specimen was
kindly placed in my cabinet by 3Ir. Wilhclm Jiilich of New
York.

88 GEORGE H. HORN, M. D.

ANELPISTUS, n. gen. (Melandryidfe.)

The genus for which the uame is proposed differs from Scotodes
Esch. by the following characters :

Tborax broader than long, sides rounded in front, gradually narrowing to
base, hind angles not prominent. Elytra very little broader than the
thorax.

This genus which may be considered the representation of Scotodes
in our fauna resembles rather an Emmesa or a convex Phn/ganophllus.
It possesses all the other characters of Scotodes even to the form of
the tibial spurs, and can be distinguished only by the form of thorax.
The latter genus, rare in Europe, is known to me only by the descrip-
tions of authors and the figure of Duval (Genera, PI. 86, fig. 429) in
which the thorax. is represented as being nearly as long as broad, the
sides strongly rounded in front, sinuate behind, with the hind angles
prominent.

A. americanus, n. sp. — ]3rownish-testaceous,slightly shining. Head densely
and coarsely punctured and sparsely clothed with cinerous hairs. Thorax
nearly black, more shining and less densely punctured than either head or ely-
tra and sparsely clothed with cinereous pubescence; one- fourth broader than
long, sub-truncate at apex, sides strongly rounded in front but gradually nar-
rowing to the hind angles which are not prominent, base truncate with a dis-
tinct imj^ression near the middle of the base of each elytron. Elytra elongate
l^arallel, moderately convex, densely and coarsely punctured and clothed with
cinereous ijubeseence, forming a more distinct band at the middle of each ely-
tion very narrow at suture, and also at the apical fourth. Body beneath black,
more shining, very finely'' and rather densely punctured, and sparsely clothed
with cinereous hair. Legs brownish testaceous tibice with apical and middle
third darker. Length .28 "£ — .34 f inch; 7— 8.5 mm,

The male has the antennae slightly longer owing to a greater elonga-
tion of joints 8 — 7. The tibij» are also very distinctly arcuate in %
and straight in $ .

The cinereous hair forming the vestiture of the elytra in the male
specimen before me appears to be more densely placed in a band across
the middle, broad at margin and rapidly narrowing to suture^ the
apical fourth is also more densely clothed. This arrangement of vest-
iture may be owing to accident in pinning, as a specimen which had
been preserved in alcohol is almost entirely nude. The male is smaller
and more slender than the female.

For the two specimens in my cabinet I am indebted to3Ir. Sanborn,
of Boston, by whom they were taken in the White Mountains of New
Hampshire.

DITYLUS, Fisch.

Ditylus bicolor, n. sp. — Color metallic blue, thorax red. Head densely not
coarsely punctured. Thorax not longer than broad, sides slightly rounded in

AMERICAN COLEOPTERA. 89

front, feebly narrowed to base which has a narrow black margin'; surface very
coarsely but sparsely punctured, feebly convex, with a median shallow impres-
sion and two oblique very vague impressions near the hind angles. Elytra
twice as wide as thorax at base, sub-parallel, metallic blue, sparsely clothed
■with short fine pale hairs, densely punctured and scabrous. Body beneath
(except thorax; and legs metallic blue, shining, very sparsely punctured and
clothed with pale hairs more densely placed on the pectus and legs. Length
.45 inch : 11.5 mm.

Differs from all our Diti/lns by its color and recalls Asdera excavata,
Lee. Resembles Xacerdes in from rather than our larger Ditylus,
but cannot be separated generically from the latter.

One specimen from Fort Klamath, Oregon. jMr. Wm. ^l. Gabb.

D. cyanipennis, n. sp. — Color bluish black, shining; elytra metallic blue.
Head metallic blue, shining, coarsely not densely punctured. Thorax black,
faintly bluish, rather coarsely and densely punctured, not longer than broad,
sides feebly rounded in front, gradually narrower to base, disc with an indistinct
impression on the median line on front, and a vague V-shaped impression with
the apex toward the basal margin. Elytra scarcely as broad as twice the
width of thoracic base, parallel, bright bluish with slight violet tinge, densely
punctured and scabrous. Body beneath metallic blue, shining, sparsely punc-
tured and with few pale hairs. Legs bluish-black. Length .30 inch; 7.5
mm.

This is our smallest Difi/lns and resembles Oxacis still more than
the preceding species, and may easily be distinguished from all others
of the genus by sculpture and color, none of our other species except
the preceding having any brilliancy, being for the most part blackish
and opaque or with very faint metallic tinge.

Coast Range of California, south of San Francisco, Mr. Wm. M.
Gabb.

Oxacis sericea, n. sp. — Brown or brownish testaceous, shining, rather densely
clolliod with greyish silken pubescence. Surface finely and densely punctured.
TJiorax longer than broad, sligiitly flattened, at the disc, sides strongly rounded
in front, gradually narrower to base ; paler than the elytra with median stripe
and sides dusky. Elytra rather robust, densely pubescent; color brown or
slightly paler with an oblique pale stripe extending from the humerus toward
apex. Body beneath black, tip of abdomen pale, densely but very finely punc-
tured. Length .28 'J, —.38 9 inch; 7 — 9.5 mm. '

In this species the last joint of the maxillary palpi may be said to
be elongate oval, broader nearer the base, apex rounded. Resembles
in color /alir/mosa but may be distinguished from all our species by
the much more dense pubescence with hairs longer and less fine. The
pubescence is so dense and closely recumbent as to hide almost entirely
the color of the elytra. As in other species this varies somewhat in
its coloration, the thm'ax being at times paler than the head or elytra,
or the entire upper surface may be uniformly brownish. The lateral

90 GEORGE II. nORN, M. D.

and sutural margins of the elytra are paler in many specimens. The

males are smaller and more slander than the females, and have the

last joint of the antennte sinuate.

I am indebted to Mr. Wm. M. Gabb, for this species, collected in

Lytta magister, n. ?p. — "Black, moderately shining; bead, thorax and legs
orange yellow. Head smooth, shining, very sparsely and finely punctured, cly-
peus, labrum and parts of mouth black. Antennse short, joints moniliform,
base of first joint yellowish. Labrum feebly emarginate, and concave and
with a slight carina at middle. Thorax smooth and shining, sub-hexagonal,
sides not prominent. Elytra elongate, parallel with strongly elevated reticu-
tations, less distinct at base and apex. Body beneath black, sub-opaque, densely
and finely punctured. Legs orange yellow, tarsi black. Male ; antennpe
thickened at middle, joints 4 — 7 somewhat flattened and much broader than
the following joints. Last abdominal segment deeply emarginate. Female;
joints of antennse gradually thicker to the tip; terminal abdomen segment
rounded. Length 1.— .1.40 inch ; 26— .36 mm.

This is the largest species known to inhabit our territory, and may
be distinguished from all our species with sub-hexagonal thorax, by
the form of male antennoe, deeply eroded or reticulate elytra and by
the legs from the coxce, excepting the tarsi, entirely yellow. No sexual
differences are seen either in the legs or spurs. The mid lie tibire in
both sexes are slightly arcuate, as in vnlnerafa. The sides of the
thorax are much more obtusel}'^ angulate than either vidnerata or
Cooppvi.

Not rare iu Owen's Valley, California. One specimen was taken in
Arizona near Gila City. They were all found walking on the ground
or feeding on plants. Although they have moderately developed
wings none were found in flight. For many of the specimens obtained
iu Owen's Valley, I am indebted to Dr. H. M. Cronkhite, Assist.

Lytta deserticola, n. sp. — Black moderately shining, head, thorax and femora
reddish yellow. Head moderately convex and shining with but few fine punc-
tures, hind angles obtuse, clypeus, parts of mouth and antennre black ; labrum
coarsely punctured, feebly emarginate. Thorax round, moderately convex with
few punctures; basal narrow margin black. Elytra moderately robust, black,
finely reticulate. Body beneath black, feebly shining and moderately densely
clothed with very short black hairs. Coxae, trochanters, tibipe and tarsi black,
femora reddish yellow except a small black space at base and tip ; legs sparsely
clothed with short black hairs. Length .76 inch; 19 mm.

Resembles cUchroa, Lee, or -i-maculata Chevr., in form, and may be
known from any of our species with rounded thorax by its finely re-
ticulate elytra and by its mode of coloration.

One female was collected south of Fort Whipple, Arizona.

AMERICAN COLEOPTERA. 01

Lytta refulgens, n.sp. — Brilliant metallic green, thorax reddish yellow with
discuidal rounded metallic spot. Head shining metallic green with frontal yel-
lowish spot ; coarsely but densely punctured. Thorax regularly rounded on
tiie sides, slightly broader than long, feebly convex and with few scattered
punctures, disc with round metallic spot; narrow basal margin black. Elytra
brilliant green, scabrous. Under surface more shining. Femora metallic
green, tibice and tarsi black. Length .38 — .40 inch; 9.5 — 10 mm,

Beloiips to the same group with stncipennis, Lee, which has how-
ever a wider thorax, and rufous vertex. The elytra are dark olive
green, and the under surface blackish green. The brilliant colors
will enable the present species to be recognised at a glance.

Specimens from Millerton, California, collected by Mr. Wm. M.
Gabh.

Lytta auriculatj, n. sp. — Body black, eh'tra greenish or bluish black. Head
with each liiiid angle and frontal spot red. Form slender, head black, coarsely
])unetured, more densely ou the front. Thorax black, rather shining, coarselj'
punctured, sub-pentagonal, sides narrowed in front, sub-iJarallel or slightly
convergent behind the middle. Elytra one half broader than the thorax,
bluish or greenish black, scabrous. Beneath black, shining, coarsely butvery
Sjiarsely punctured, and with slight pubescence. Length .35 — .46 inch; 9 —
1 1.5 mm.

IJelongs with aeneipennis and sniaragduhi^diiSarm^ by its more
elongate from sub-pentagonal thorax and color. The antennae are long,
nearly two thirds the length of body.

Several specimens from Kern River region of California; found on
a small species of Lupin in flower.

Lytta compressicornis, n. sp. — Brilliant blue sometimes slightly violet.
Head entirely blue, very coarsely but sparsely punctured. Thorax narrower
than the head, sub-quadrate, feebly narrowed at base, moderately convex, vvrth
few coarse irregularly j^laced punctures. Elytra twice as wide as thorax, finely
scabrous, gradually wider toward apex. Body beneath blue, shining, S)»arsely
jiunetured. Legs, mouth and anttnnte black. Anteunse with joints 5 — 11
i^trongly compressed in both sexes, broader in the male. Length .30 — .50 inch ;
s — 12 mm.

In both sexes the spurs of the hind tibia) are slender and acute,
the inner longer. The tibiae are straight. This species differs how-
ever from any previously described, at least in our fauna, in having
the antenna; very strongly compressed. The joints from 5 to 11 are
transverso, unu-e than twice broader thin long. The antennae are
short, not longer than head, ami thorax. The male hus the last ab lo-
minal segment more deepl3' and acutely emarginate than is usual in
the species allied most nearly in general appearance, e.g. co/iwcxo, Lee.

From Owen's Valley, California, collected on a plant resembling our
Canada thistle but with yellow flowers.

CALOSPASTA, Lee.
Calospastanemognathoides, n. sp.— Body black, moderately shining. Thorax
rufous. Head black, shining, scarcely punctured. Thorax rufous, sub-quadrate,
sides moderately rounded, feebly narrower in front ; disc moderately convex,
shining with very fine punctures. Elytra at base one half broader than the
thorax, broader behind the middle, scabrous, black. Body beneath black,
shining and with few short yellowish hairs, abdomen sub-opaque. Legs black,
shining, sparsely but coarsely punctured and with few yellowish hairs. Length
.36 inch ; 9 mm.

Resembles JSfemognatha atripennis, Lee, in appearance. The tarsal
claws are as in C. elegans, Lee, the two portions of each claw connate,
the under shorter than the upper. The antennae are as in 0. elegans.
The surface has been entirely deprived of pubescence.
One female from Owen's Valley, Cal.

C. perpulchra, n. sp. — Shining blue, elytra with a large humeral spot, median
transverse band and sub-apical yellow spot. Head coarsely but sparsely punc-
tured. Thorax longer than broad, narrowing in front, sides behind the middle
sub-parallel ; disc moderately convex, shining, coarsely but sparsely punctured.
Elytra nearly twice broader than thorax, parallel, scabrous, moderately convex,
sparsely clothed with yellowish hairs. Beneath bluish, shining, sparsely
clothed with short yellowish hairs. Length .28— .40 inch, 7—10 mm.

This species varies greatly in its markings. One specimen in my
cabinet is entirely blue ; two have the humeri alone yellow ; the
greater number have a humeral space and irregular transverse band
behind the middle yellow, not attaining either suture or margin, others
have a sub-apical spot in addition. The sculpture of the front varies
considerably. In some specimens the surface is irregular without any
definite formation of ridges or depressions; one specimen has a moder-
ately convex and prominent tubercle within the insertion of the
antennae; others again have a broad median groove bounded by a
ridge on each side and a smaller tubercle within the insertion of the
antenna, limited within by a slight groove. This species may be dis-
tinguished from any varieties of elegans by the more elongate thorax,
surface more shining and very much less densely pubescent.

Collected in Owen's Valley, and Posey Flat (S. E. Sierra region)

California.

In the males the front is deeply grooved at middle with a prominent

tubercle within the base of the antennae, the basal joints of the anterior

tarsi are also distinctly dilated.

acute at its apical end. With the known variation of the preceding;
.species I am unwilling to separate this as distinct but prefer to con-
sider it nearly a variety under the name of hiimera/is. Both males
and females are before me, the anterior tarsi of the male as distinctly
dilated as in the preceding species. The typical specimens in the
ca'tinet of Dr. Leconte are females, hence the failure to mention this
very obvious character. In the male the front is rather deeply sulcate
but the lateral tubercle is less evident than ia the male of i^crpnl-
chra.

C. mirabilis, n. sp. — Palo rufous, elytra pale yellowish. Head broadly oval,
gibbous between the bases of the antennse, sparsely puncture>l. Thorax oval,
as broad as long, strongly narrowed in front, and slightly narrower at base ;
median and ba-sal impressions moderately deep. Elytra oblong, broader be-
hind, humeri moderately prominent, margin reflexed, suture elevated, and
with four strongly elevated eostre on the disc of each elytron, extending from
base nearly to apex. Color pale yellow, with four small brown spots at base,
arranged in arc with convexity backwards, an iriogular narrow transverse
band at middle interrupted by the costoe, and a narrower sub-apical band.
Body beneath and legs, pale rufous, abdomen paler and more shining. Length
.46 inch ; 11.5 mm.

The entire surface of body is very sparsely clothed with very short
silvery white hairs, longer on the legs. The intervals between the
elytral cost39 are nearly flat and sparsely punctured. The small
brown spots at base are arranged between the suture and first ccsta,
and between the first and second. The tarsal claws are divided, the
upper and lower portions being connate, and the latter shorter. The
antenna; are as in the other species of Caloapanta. With one excep-
tion (^Pieuropompha costata, Lee), this is the only Meloide in our
fauna with costate elytra.

The specimen in my cabinet is from Southern Arizona, and was
obtained through the Agricultural Bureau at Washington.
Tegrodera erosa, Lee. Ann. Lye. V, 159.

Two varieties of the species occur. Specimens collected by 3Ir.
Gabb in Lower California have the elytra very coarsely reticulate and
the transverse black band entirely wanting. Those collected by my-
self in Owen's Valley have the elytra more finely reticulate and a
broad median and apical black band. Specimens from San Diego are
nearly intermediate in sculpture and color. I am unable to detect any
differences of a specific nature. The male has the last segment of ab-
domen slightly eujarginate.

Zonitis longicornis, n. sp. — Elongate, pale brownish testaceous; opaque;
margin, suture and narrow stripe extending from humerus to tip paler. Ileail
nearly black, verte.x paler very densely and coarsely punctured, rugose.

TRANS. AMER. ENT. SOC. (13) JUNE, 1870.

94 GEORGE H. HORN, M. D.

Thorax as broad as long, sides rounded and narrowed to base ; disc with broad
darker space at middle ; densely and rather coarsely punctured. Elytra
elongate, parallel, sutural and lateral margins and narrow oblique stripe ex-
tending from the humerus to near the apex, pale testaceous; densely punc-
tured and scabrous. Body beneath brownish, densely punctured. Legs densely
punctured; coxse, base and apex of femora, base of tibiae and proximal end of
tarsal joints pale testaceous. Antennae long, slender, testaceous, equalling three
fourths the length of body. Length .40 inch ; 10 mm.

llesembles Epkauta rather than Zonitis, and may be distinguished
from all our species by its long antennne and very densely punctured
surface as well as by the system of coloration.

One specimen from Central Illinois, is known and had been, from its
form placed among the species of Epicauta in my cabinet.

GNATHIUM, Kirby.

The characters separating this genus from Nemognatlia are very
slight, and the addition of new species seems to be gradually lessening
their value, the only character remaining being a slight thickening of
the outer joints of the antennae.

Our species are as follows :

Color j^ellowish- testaceous.

Elytra opaque, densely punctured.

Thorax elongate minimum.

Thorax not longer than broad, sides strongly rounded texanum.

Elytra shining, feebly punctured; thorax campanulate nitidum.

Color black, thorax yellowish testaceous.

Elytra coarsely, not densely punctured flavicolle.

G. minimum. Say, Journ. Acad. Ill, p. 306.

Diifers from the following species in the form of thorax which may
be described as very elongate oval slightly flattened above, sides feebly
rounded, truncate at base and apex. The surflice is evenly punctured
the punctures moderately coarse, much more so than in any other
species known to me. The elytral punctures are coarser and more
densely placed ; surface with semi-recumbent hairs which vary in
color. Body beneath, darker in color, sometimes brown with the legs
dusky. In the species with dark under surface the hairs are black,
when pale or similar in color to the upper surface the hairs are also
pale. Length .30 inch; 7.5 mm.
Kansas, New Mexico and Texas.

G. texanum, n. sp.

Similiir to minimum but smaller. Thorax not longer than broad,
wider in front of middle, sides strongly rounded in front. Surflice
sparsely and irregularly coarsely punctured. Elytra more finely and
less densely punctured than in minimum, and sparsely clothed with

AMERICAN COLEOPTERA.

short black hairs, scmi-recumbent near the base and erect behind the
middle. Body beneath slightly darker than the upper surface. Length
.25 inch ; 6.5 mm.

This species may be distinguished from mhiimum by the form of
thorax. The head is also less elongate, and the nia.xillary prolon<ic;i-
tions about one and a half times the length of head. In the
preceding species they are longer than half the entire length of
body.

Specimens were collected by Dr. A. L. Heerman in Texas.

G. nitidum, u. sp. — Form slender, color yellowish testaceous, shining. Head
shining, densely punctured within the eyes, vertex smooth. Thorax campanu-
late, slightly longer than wide ; surface smooth, shining with few fine widely
scattered punctures. Elytra shining with fine distantly placed punctures ar-
ranged in irregular striae. Body beneath pale brownish, legs yellow. Autennee
black, first and sometimes second joint pale. Length .20 inch ; 5 mm.

Differs from all our species by its shining surface, llecent speci-
mens have but few rather longer hairs than either of the preceding
species. The head is less elongate, the hind angles more rounded and
the maxillary prolongations scarcely longer than the head.

.'Specimens were collected in Owen's Valley, California.
G. flavicoUe, Lee. Journ. Acad. Ser. H. iv, p. 24.

From all the preceding species it differs in color, having the entire
body black except the thorax, which is yellow. It appears to resem-
ble /^-anciYfoji/, Kirby, and for the sake of comparison and future ease
in study I append the original descriptions.

mate each other very closely. The type of flavicolle does not seem to
be a fully developed specimen of the species to which it belongs. It
must also be seen that Ivirby's description of the thorax hardly corres-
ponds either with itself or with ovx flavicolle where he writes " camp-
anulate — and very short." Kirby's description may be found in Lia-
nean Transactions, sii, p. 424.

Mycetina pallida, n. sp, — Elongate, pale rufo-testaceous, moderately shining.
Thorax sparsely and very finely punctured, longitudinal and basal impressions
well marked. Elytra less shining, very finely but sparsely punctured and
with minute hairs. Beneath more distinctly punctured, paler ; prosternum
narrow, depressed. Legs slightly darker than the under surface; antennas
brownish. Length .26 inch ; 6.5 mm.

A female specimen in the cabinet of Dr. Leconte, received by Dr.
S. Lewis, from Colorado.

Eesembles in form M. Iseta (Lee.) and not differing from that
species in the relative size of its parts. Differs from all our species in
its entirely uniform pale rufo-testaceous color. The elytra are some-
what more opaque than the rest of the surface and under high power
are very finely alutaceous, and with rather sparsely placed fine punc-
tures, each bearing a minute slender hair.

M. limbata, u. sp.— Piceous black, shining ; entire upper surface with fine
sparsely placed punctures, each bearing a very minute hair, those of the thorax
less distinctly imjiressed ; transverse and longitudinal impressions of thorax
distinct tliough not deep. Elytra piceous black, entire margin from humerus
to apex testaceous and with a narrow band extending inwards from the middle
of margin slightly obliquely towards the suture without attaining it. Antennse
not closely articulate and with the palpi, ferruginous. Under surface black,
Bub-opaque, more coarsely j^nnctured than the iipper surface. Legs ferrugin-
ous. Length .18 inch; 4.5 mm.

This species has exactly the forui of Emlomychus higuttatus^ and may
be easily distinguished from any of our species of Mjjcetlna^ by the
system of coloration. Belongs to same group with perpiilchra in which
the mesosternum is broader than long and sub-pentagonal. The pale
margin of the elytra becomes much broader toward the apex and ex-
tends slightly along the suture.

Occurs in California. For the unique in my cabinet I am indebted
, to Mr. James Behrens, of San Francisco.

Epipocus unicolor, n. sp. — Rufo-ferrugineus, sparsely clothed with short
golden hairs. Head rather densely and coarsely punctured. Thorax one-half
broader than long, deeply emarginate in front, angles obtuse; sides rounded in
front of, sinuate behind middle, hind angles acute, moderately prominent; disc
coarsely but rather sparsely punctured between grooves, more finely and densely
toward the sides ; grooves moderately deep and slightly convergent and ex-
tending two thirds toward apex. Elytra broader at base than thorax, moder-

ately convex, apices obliquely truncate with the outer angle more prominent;
surface equally punctured, punctures not coarse, more densely placed than on
thorax. Body beneath, legs and antennae similar in color to upper surface.
Meso- and metathorax sparsely, abdomen finely, epipleurse coarsely punctured
and sparsely clothed with golden hairs. Antennce nearly half the length of
body, thirdjoint slightly longer than fourth. Hale with minute spur on inner
side of anterior tibire below the middle. Length .22 — .28 inch; 5.5 — 7 mm.

Colorado, Dr. Samuel Lewis. Very abundant under damp logs at
Camp Grant, Arizona.

This species is evidently allied to lonrjicornis, Gerst., of which speci-
mens are unknown to me. This species appears from the description
to be abundantly distinct from the one above described, and is about
equal in size. Resembles 'punctatus, Lee, in form.

Engis californica. n. sp. — Elongate oval. Head ferruginous, moderately
coarsely but not densely punctured. Thorax ferruginous, one-fourth broader
than long, sides moderately rounded from base, scarcely narrow at apex; disc
moderately coarsely and densely punctured. Elytra not broader than thorax,
black or brownish with a humeral spot ferruginous; surface with regular strife
of fine punctures moderately closely placed. Body beneath brownisl^ with the
entire margin and tip of abdomen somewhat paler. Legs ferruginous antennae
brown. Length .10 — .14inch; 25 — 3.5 mm.

This species may be readily distinguished from qnadn'maculata, by
the ferruginous head and thorax and by the elytra having only a
humeral pale spot. The latter is irregular in form and extent, usually
gradually vanishing in the darker color around it. The thorax is
also less rounded in front, more convex and densely punctured. It
resembles somewhat the figure of E. humeralis^ Fabr. (Duval, Genera,
pi. 75, fig. 357), but the thorax is more rounded and scarcely nar-
rowed in front.

Specimens in my cabinet from Fort Crook, Sacramento, and Fort
Tejon, Cal. Occurs under bark or in fungi.

Descriptive Catalogue of the species of NEBRIA and PELOPHILA of the

United States.

BY GEO. H. HORN, M. D.
The two genera Xehria and Pelophila appear to be sufiiciently distinct
to be retained apart. The following tables, the result of a short study
of our species, may be useful to those to whom the widely scattered
specific descriptions are inaccessible.

NEBBIA. — Anterior tarsus of male moderately or feebly dilated; antenn.-c
slender, joints all cylindrical, equalling in length two-thirds or more
the length of the body ; scutellar stria of elytra always distinct.

spots. Thorax similar in form to metallica, but with the sides less rounded in
front; anterior angles obtuse, hind angles rectangular, base feebly emarginate

at middle; disc feebly convex, sides very narrowly margined, margin slightly
reflexed, surface smooth, anteriorly slightly rugose, at sides more rugose and
punctured, base deeply transversely impressed, and a deep impression within
the hind angles, coarsely but sparsely punctured and rugose. Elytra elongate-
oval, humeri totally obliterated, surface rather deeply striate, strire distantly
punctured, interspaces feebly convex. Body beneath sAiooth, black, shining.
Legs black, long, slender. Lengsh .55 % — .64 9 inch ; 14 — 16 mm.

Head short and robust, eyes less prominent than in any other of
our species. Sides of thorax moderately rounded in front, strongly
sinuate behind, hind angles strictly rectangular. The lateral margin
of thorax very narrow and feebly reflexed. Anterior transverse im-
pression faint, longitudinal, distinct but not strong. Elytra elongate-
oval, sides rounded, slightly broader behind the middle in the male.
The strife are nearly as deep as in pallipes, distantly punctured, in-
terstices feebly convex and without dorsal punctures.

The Male, has the anterior tarsi feebly dilated ; last abdominal seg-
ment with a broad shallow excavation divided longitudinally by a
ridge.

The Female, has a narrow coriaceous band between the third and
fourth abdominal segments at middle.

Resembles by its elongate form gregaria, Esch., but easily known
by the oval elytra, the thorax narrower behind, and less marginel on
the sides.

The mentum, at the base of the emargination, is not armed with a
broadly emarginate tooth, but distinctly bisinuate, the ligula is feebly
prominent. As the form of the mentum tooth and the degrea of its
emargination vary, I have not thought it advisable to separate it, from
Xehria as a distinct genus.

Two specimens of this species were collected by the Geological
Survey party under Prof. Brewer, in the high Sierra Nevada 3Ioun-
tains east of Visalia, California.

This species is easily known by its pale yellowish testaceous color,
and oval elytra, with the humeri rounded. The species is not apter-
ous, the wings being very distinct but rather poorly developed. The
elytra have more distinct stria), moderately deep but impunctured.
The number of large punctures in the stride is rather variable, and are
in the third four, fifth two, and sixth three, usually. The eighth
striae has however very many large punctures causing, the edge of the
next outer interval to appear coarsely serrate. The sides of the
thorax are feeblv sinuate at base but the anirles are not rectangular.

Three specimens from Cape Flattery, Oregon.

N. virescens, (Chaud. inedit.) — Bluish-green, metallic, shining. Head on
each side within and Slightly before the eyes sub-triangnlarly impressed and
rugose. Thorax about one-third broader than long, sides broadly rounded in
front, oblique behind, hind angles inoderately prominent, but not rectangular;
margin moderately broadly reflexed; apical transverse imj^ression very faint,
longitudinal impression distinct, basal impressfon broad, rather deep, angular
impressions broad, not linear; surface feebly convex, snaooth, sparsely punc-
tured at basal margin. Elytra oblong, feebly convex, but not flattened, sides
sub-parallel, feebly rounded : surface feebly striate, striae scarcely evident at
the sides, distinctly punctured, diseal intervals very feebly convex, third strife
with two larger punctures, one in front of middle another about one-third from
apex. Body beneath and legs black, smooth and shining. Species winged ;
humeri moderately prominent. Length .48 inch ; 12 mm.

This species may be readily recognised by its color and by the sides
of the thorax being nearly rounded from apex to base, being but
slightly oblique behind with the angle not rectangular,

A single specimen is in the cabinet of Dr. Leconte sent probably by
M.'Sall^ under the name cited. I know of no description published,
and therefore give the characters in detail. The specimen is said to
be from Vancouver.

more elongate. Color metallic-green changing to cupreous and violet.
The thorax is less broad than in mefalltca, sides less rounded, margin
moderate, distinctly reflexed, hind angles rectangular, but less dis-
tinctly than in the species mentioned. The elytra are sub-parallel,
feebly striate, stria3 very faintly punctured. Interstices flat, the third
with five or four punctures, the seventh with three. Length .40 inch;
10 mm.

Occurs only in Russian America.

N. viridis, n. sp.— Brilliant metallic-green. Head smooth, impunctured,
with vague frontal impressions. Thorax similar in shape to Salhbergi, one-
half broader than long, sides strongly rounded in front, deeply sinuate behind,
hind angles rectangular, margin slightly reflexed; surface smooth with coarse
punctures along the margin, and in the basal transverse impression; apical
and median impressions moderate, basal impression deep. Elytra parallel,
humeri moderately prominent, surface moderately convex, distinctly striate,
striae finely but distantly punctured, intervals feebly convex and with five
impressions on the second, the first two very distant, those toward the apex
close. Body beneath black, antennae, palpi, and legs rufous. Length .30 inch;
7.5 mm.

This species may be readily known by its color, being the only spe-
cies of an uniformly metallic-green in our series.

Two specimens received by Mr. Ulke from St. Michaels,
Alaska.
N. obliqua, Lee. Proc. Acad, 1S66, p. 363.

This species resembles N. Mannerheimn, Esch., but has the sides
of the elytra more nearly parallel. The third stria has a single
puncture at about one-third from the apex, and a very faint trace of
another still nearer the apex. The striae are rather deep, scarcely
punctured, the intervals flat. The color is black, without any trace
of metallic lustre, the legs are piceous and the tarsi, antennae and
palpi paler. Length .44 inch; 11 mm.

I have seen two specimens from Colorado.

N. suturalis, Lee. Agass. Lake Super, p. 209. — Black, sometimes shining, de-
pressed. Sides of thorax oblique, as in the preceding species. Elytra with
sub-parallel, feebly rounded, sides; surface moderately deeply striate, strife
distinctly but irregularly punctured, intervals flat; third striae with four dis-
tinct large punctures. Length .40 — .41 inch; ^10—11.5 mm.

Occurs ill the Lake Superior region, and in uortliorn Xew Hamp-
shire.

N. hudsonica, Lee. New Species, p. 3.

Closely related to Sahlhergi, hut diflfers in its more depressed form
aud by hind angles of the thorax being scarcely rectangular. The
sides of the thorax are less rounded in front and feebly sinuate be-
hind, and it thus approaches ohliqiia in form The sides of the ely-
tra are nearly parallel, the surface faintly striate, the striae scarcely
punctured, and the third with four larger punctui'es rather vaguely
defined. Length .40 — .42 inch ; 10 — 10.5 mm.

p. 209.

This species is somewhat viiriable in the form of the thorax. From
typical specimens in Dr. Leconte's cabinet, and a long series of speci-
mens, the following specific characters have been drawn.

Head smooth, impunetured, frontal impression shallow. Thorax one-half
broader than long, sides strongly rounded in front, sinuate behind, hind angles
always rectangular, sometimes slightly prominent outwards; lateral margin
moderately reflexed, and with few coarse punctures within, basal transverse
impression moderately deep and sparsely coarsely punctured; median and
apical impressions moderate. Elytra sub-parallel, faintly striate, striae dis-
tinctly punctured, third stria with four, sometimes five moderately distinct
large punctures, intervals flat. Body totally black, legs piceous or castaneous,
with the tibiae at times paler. Length .40 inch; 10 mm.

The form called by Dr. Leconte, moesta, is slightly more depressed,
in other respects not diifering from the true type. In the 3ISS. of
the late Dr. Zimmerman the opinion is expressed that the Ilelohia
(^Nehria') casfanipes, Kirby, is identical with this species. The des-
cription of Kirby applies much more nearly to this than any other of
our species, and is moreover the most abundant species in the region
from which the collections sent to Kirby were derived. The descrip-
tion of Kirby certainly does not apply to the species to which it is
attached in the cabinet of Dr. Leconte, which is moreover found as
far as known only in upper California and Oregon.

This species has a wide distribution, being found along the Pacific
region from Sitkha to Oregon and eastward to New Hampshire.

N. bifaria, Mann. Bull. Mosc. 1853, iii, p. 128.— Black, shining. Thorax
rather small, disc transversely wrinkled, especially toward the sides, sides
strongly rounded in front, sinuate behind, hind angles sub-rectangular. Ely-
tra sub-parallel, rather deejily striate, striae punctured, intervals convex, the
third with four, the fifth with ^three large punctures. Body beneath black,
femora rufous, tibiae black. Length .40 inch; 10 mm.

1 have seen but one specimen from Alaska, collected at St.
Michaels.

N. Rathvoni, Lee. Trans. Am. Phil. Soc. x, 400.

With this species begins a small series in which the sides of the
elytra cease to be sub-parallel and become rounded, and the form is
therefore oval. The thorax is similar in form to Sahlhergi\ the hind
angles being very distinctly rectangular. The elytral stria3 are not
deep, and finely but not closely punctured, the interstices are flat, the
third with three, the seventh with five larger punctures. Body en-
tirely black. Length .48 inch; 12 mm,

A single specimen from Sacramento, California, is known in collec-
tions.

N. Mannerheimii, Fisch. Ent. Russ. iii, 253, pi. 14, fig, 5 ; Esch. Zool. Atlas,
183.3, p. 23.

Closely allied to the preceding, and diifering only in having the
hind angles of the thorax less distinctly rectangular, and in a different
arrangement of the larger punctures of the elytra. The elytra arc
also more broadly rounded and are faintly striate, the stria; however
varying in depth and distinctness of punctation in difi'erent specimens.
The third stria has five very distinct large punctures. The intervals
are flat. Body entirely black, antenna6, palpi and tarsi castaueous.
Occurs in Alaska and Vancouver Island.

The description of Mcnetries applies so distinctly to that marked
castanipes in our cabinet that I cannot do better than translate the
original.

"Black; elytra elongate oval, striate, strite obsolctely punctured, and with
three impressed punctures ; a/ntennce and legs pale rufous.

" It has very nearly the size of X. Manner heiviii, but the el^'tra have a more
oval form, being however a little less broad at the base; it is black, with an-
tennae and legs clear red, the palpi are rufous, also the mandibles which arc
brownish at the tip ; on the upper surface of the head near each eye a small ob-
long rufous spot. The thorax is rather broader at its middle than the above
cited species, and slightly more convex. The elytra are striate, the strise faint
and slightly punctuate, the intervals are more flat, and on the third stria may
be seen three moderately large impressed punctures. From California. Length
.40_.46 inch; 10—11,5 mm.

To the above description might be added, "hind angles of the thorax
distinctly rectangular," and nothing further is necessary to render evi-
dent what Menetries had in view when the description was being
written.

Three specimens are before me ; one in Dr. Leconte's cabinet is a

duplicate of the above description, two in my owa calbinet have the
elytra more deeply striate.

One specimen from Oregon, two from California, the latter pre-
sented by Messrs. Edwards and Behrens of San Francisco.

N. pallipes, Say, Trans. Am. Phil. Soc. ii, p. 78.

The species is so widely distributed over our country and is so well
known that an extended description is unnecessary. It may be known
by its very broad thorax with strongly rounded sides, oblique behind,
with angles obtuse, not rectangular. The elytra are deeply striate, the
striae punctured, the third having fine very distinctly impressed longer
punctures; interspaces convex. Antennae and legs pale rufous or
yellowish. Length .40 — .46 inch ; 10 — 11.5 mm.

Distributed through a region northward from the fourtieth parallel,
and east of Mississippi River.

PELOPHILA, Dej.
The characters given at the beginning of this paper seem to warrant
the retaining of the genus as distinct from Ay^ria. Our species are few
and agree in their robust form and stout antennas, and all have the
hind angles of the thorax rectangular.

On the species of OODES and allied genera of the United States.
BY GEO. II. HORN. M. D.

The description of our ^species of the genera allied to Oodes are so
widely scattered as to make reference to them in many instances diffi-
cult, while the descriptions of Chaudoir are inaccessible except to
those having access to the large scientific libraries, and at the sugges-
tion of several correspondents, this and the two preceding papers have
been prepared.

1C6 GEORGE n. HORN, M. D.

Four genera are recognised in the Classification of Coleoptera of
North America hy Dr. Leconte, two liaving four dilated joints to the

This species is elongate, parallel, and very feebly convex. The
sides of the thorax are distinctly rounded in at the base, so that a dis-
tinct angle is formed between the sides of thorax and elytra. The ely-
tra are finely seven-striate, the strias distantly punctulate, intervals
flat, and when seen under high power, finely alutaceous, the third
having near the apex a single small puncture. Color entirely black,
with no metallic lustre. Length .42 inch; 10.5 mm.

Occurs over a wide region; Pennsylvania, Georgia and Missouri,
but is by no means abundant.

Occurs in Louisiana, Texas, and Missouri.

OODES, Bon.
Our species, although more numerous than those of all the other
genera taken together, are at present but eight in number, and have
been divided into three genera by Chaudoir, (Bull. Mosc. 1857, iii,
pp. 20 — 21), which may here serve as a basis for their illustration in
tabular form.

Striae punctured, seventh replaced by a row of indistinct puuctures-.tszanus.

0. amaroides, Dej. Sp. v, C64.

This species is the smallest of the group to which it beloniis, and
recalls in its general aspect the species of Ajnai-a allied to impuncti-
coUis. The sides of the thorax are rounded and gradually broader to
the basal angle and not as in the two succeeding species narrower at
base than at a short distance in front. The median and basal impres-
sions are so fliint that they may be called obsolete. The elytra have
feebly rounded sides, are sub-parallel and very obtuse at apex. The
striae are moderately distinct, finely punctured their entire length, but
less distinctly at apex, the seventh being fully as distinct as the two
preceding stride. The intervals are flat, that between the second and
third striae with two distinct punctures. The meso- and metasternal
side, pieces are coarsely punctured, the sides of the abdomen rugous.
The legs are piceous-black. Length .30 — .36 inch ; 7.5 — 9 mm.

Occurs from Pennsylvania to Texas, and westward to Kansas. Not
abundant.

0. americanus, Dej. Spec. II, 377. — Black shining. Thorax gradually broader
from apex to base, slightly narrower at base than immediately in front, sides
rounded, disc feebly convex, and with the median impression distinct but not
deep. Elytra sub-parallel, very obtuse atape.^,seven-striate, striae moderately
deep, distinctly and closely punctured, intervals feebly convex and with two
punctures as in the preceding species. Meso-and metasternal side pieces
coarsely punctured: sides of abdomen punctured and finely wrinkled toward
the hind margins of the segments. Length .50 inch; 12.5 mm.
Occurs from Pennsylvania to Georgia, but not common.

0. fluvialis, Lee. New Species, p. 13.

■ Allied to the preceding species, but narrower and more convex.
The sides of thorax'are less rounded in at base, the median line more
distinct and the elytra proportionally longer. The stria3 of the elytra
are less deep, are very finely and distantly punctured. Intervals flat,

Less elongate than the preceding species. Color aeneous-bronze,
less shining. Thorax with sides slightly more rounded, hind angles
rectangular but not well defined at tip. Striae of the elytra very dis-
tinct, deeper than either ciipreeus or eler/ana, and entirely impunctured.
the seventh obliterated; intervals flat, the third with two faint punc-
tures as in cvprseus. Body beneath as in ctqjrsens. Legs entirely
piceous. Length .40 inch ; 10 mm.

The characters thus summarily given will serve to distinguish it
from cupratus or elcgans. As in the former species the thorax is as
broad at base as the base of the elytra, and both have the first tarsal
joint of male shorter and less distinctly pedunculate than the following
species.

Occurs in Louisiana.

0. elegans, Lee. Ann. Lye. v, p. 180, — Form elongate. Color cupreous-metal-

punctured faintly only at base, seventh totally obliterated, intervals flat, dis-
tinctly alutaceous, and with two punctures, as in cuprceus, placed near the

Description of tlie species of APHODIUS and DIALYTES of the United

States.

BY GEO. H. HORN, M. D.

The fullowiug essay presents to the student a list of all the species
of Aphodius known from North America, north of Mexico, and con-
tains the results of many years careful collection of specimens from
every region of our country by personal labor or through the kindness
of many correspondents who have all promptly responded to the re-
quest for the loan and gift of specimens. The basis of the work was
found in the admirable collection of Dr. Leconte, and around this all
new species have been arranged. Several types of Alaskan species
have been of much value in determining their correct positions as well
as those of allied forms unknown to us in nature.

The species have been arranged in groups for the most part equiva-
lent to those of Erichson (Insecten Deutschlands) while several new
ones have been indicated for our West Coast species.

The genus Dialtjtes Harold, (Coleopterologische, Hefte V, 1869, p.
101) differs from Aphodius in the structure of the anterior tibise on
which the 'two upper teeth are obsolete, the third at the angle and
acute, while the fourth is anterior and projects forward over the in-
sertion of the tarsus. The head is strongly deflexed, the front not
carinate nor tuberculate. Eyes partially hidden.

A fuller comparison of the genera will be made when sufficient
time shall have elapsed for the completion of the remaining species
and genera of the tribe.

APHODIUS, II] ig.
Our species of Aphodius have become quite numerous in collections
but present various characters by Avhich they may be divided into
groups, each containing but small series of species, and the study is
therefore rendered comparatively easy. We may divide the genus pri-
marily into two sections;

Scutellura elongate, equaling i or one-fifth the length of Ihe elyir a,... Section I.
Scutellum short, as broad or broader than long, never ex-
ceeding in length i or one-tenth the length of the elytra Section II.

Section I is composed entirely of large species, in our fauna, al-
though not containing all our large speics. It may be again sub-divi-
ed as follows.

c^'

AMERICAN COLEOPTF.TIA. HI

Group A. — Body very convex, elytra not truncate at apex ; head tuberculate ;
anterior femora not fimbriate; anterior tibiae above tlie upper tooth en-
tire, not serrate; anterior sjuir of middle tibiae slender, conspicuous ;
middle and hind tarsi with first joint at least as long as the three follow-
ing; apex of hind tibiae fringed with sliort equal spinules.

This grotip corresponds with Teucheatks, Muls., and contuius but

one species introduced iuto the Canadian fauna from Europe.

A. fossor, Linn. {Scarabaeus) Fauna Suec. p. 134.

Oblong, convex, black, shining; elytra finely punctate-striate"; front tritu-
berculate.

Male. — Middle frontal tubercle prolonged into a short horn ; thorax slightly
impressed in front; anterior tibire with an elongate spur obtuse at ti]:). Length
% 3()— .48 inch ; 9—12 mm.

Female. — Frontal tubercles small, equal; thorax not impressed; anterior
.tibiiB with a more slender, acute spur.

This species is said to vary in having reddish elytra.
Specimens have been received from Canada and the Xew England
States.

As this species is so well known abroad and may be readily recog-
nised by student of our fauna by its large size and peculiar characters,
I have contented myself with copying the short but characteristic de-
scription of Erichson.

Group B. — Form elongate oval, sub-depressed : head not tuberculate ; anter-
ior femora (especially in % ) fimbriate with moderately long hairs; outer
edge of anterior tibiae usually serrate above the upper tooth ; anterior
spur of middle tibiae "J, short robust, not conspicuous, that of female longer,
more slender and acute ; middle and hind tarsi with the first joint
elongate, that of the hind tarsus of male deformed; apex of hind tibiae
frimbriate with unequal sjiinulcs.

The deformity of the first hind tarsal joint of the male is a peculiar,
ity not known to me in any species outside of this group. The joint
may be described as V-shaped, attached to the tibia3 by the longer
and broader branch, the other being shorter, more slender and acute
at tip. The inner or anterior spur of the middle tibia is short, rather
robust and partially concealed, being scarcely longer than a fourth of
the outer spur. The spur of the anterior tibitc of male is very broadl}'
spatulate and varies somewhat in accordance with the species, that of
the female being much more slender and sub-acute at tip. In all the
species the front is broadly rounded, slightly emarginate at middle.

This Section is probably equivalent to Colobopferiis, Muls., but I can
find no uiention of the peculiar sexual characters in an specific descrip-
tion.

112 GEORGE n. HORN, M. D.

The followinpj table will enable our species to be recognised :

Pygidium entirely covered by the elytra in Ijoth sexes.
Base prothorax with distinct entire marginal line.

This species has a much more robust facies than pinguis. The
thorax is more convex and shining and with fewer large punctures at
the sides and scarcely any at the base. The legs are more robust and
the first hind tarsal joint of male is more strongly developed than in
any of the species of the group. The color of the upper surface is

The description of Say is by no means characteristic and may with
equal propriety be referred to several of the species of the group.
Harold (Catalogus p. 1049,) has admitted the synonymy of liCconte's
species with Say's (suggested as probable by Keconte himself Jjist. p
3 i) and with this before me I have no doubt whatever of the identity
of soi/i(fariiis and ani/it/aris. Harold's description is exactly equiva-
lent to the typical specimens of Leconte.

This species may be distinguished frona all of those now known by
the very (for this group) convex elytral interspaces and the rather
closely and often crenately punctured stria;. The thorax is sub-quad-
rate, sides very feebly rounded, basal edge distinctly margined at the
sides. The coarse punctures are more numerous in this species and
more densely placed towards the sides and base and with no fine punc-
tures. The head appears unusually small, by the gena) being very
little prominent and obtusely rounded. The anterior tibijB have the
outer edge above the upper tooth simple and not at all serrate. Length
.27 — .30 inch; 7 — 7.5 mm; (3 — 1] lines, Harold.)

Similar in form to pinguis. Color black, shining, elytra occa-
sionally entirely or with the base and sides only brownish. Head
smooth, with but few coarse punctures in front. Thorax with distant
coarse punctures over the entire surface, very sparse on the disc, more
abundant toward the sides and base, and with very few of the finer
punctures as described in pitu/iiis ; basal edge with .scarcely any trace
of marginal line. Elytra as in piixjuis ; striic faint, scarcely punc-
tured, interstices flat, usually inqiunctured. ('olor beneath as in
2)iii(jnis. Anterior tibise with outer edge serrate above upper
tooth. Sexual characters as in jiiin/m's, but with tlie first joint of
hind tarsus of male less developed. Length .24 — .32 inch; G — 8
mm.

In the series before me I am unai^le to separate the species de-

114 GEORGE II. HORN, M. D.

scribed b}' Leconte as 07niss'iis. The interstrial spaces of the elytra are
usually entirely without punctures, in some however the punctures
are more or less distinct, and the separation of the latter species on
this character above appears not to be warranted.

Specimens occur from Lake Superior to Oregon. Those from the
latter region and Dacota are those in which the interspaces are punc-
tulate.

A. torpidus, n. sp. — Elongate oval, black, shining. Head finely and sparsely
punctured, front broadly rounded, broadly emarginate at middle, and slightly
but very distinctly sinuate near the gense. Thorax broader than long, convex,
with coarse punctures at the sides and base, very distantly placed, and with
very few finer punctures near the sides; sides moderately rounded, gradually
narrower from base to apex (when viewed from above), distinctly margined,
base margined at the sides. Elytra as in pinguis with the strise rather broad,
moderately deeply impressed; are coarsely but distantly punctured, inter-
spaces flat, scarcely punctulate. Beneath black, coarsely not densely punc-
tured, legs, brownish, antennre pale, club darker. Anterior tibice distinctly
serrate above the upper tooth. Sexual characters as in pinguis. Length .36 —
.40 inch; 9—10 mm.

This species may be readily distinguished by the very distinct sinu-
ation of the sides of the front near the gente, and by the very distinct
marginal line at the sides of the base of the thorax. The elytra are
not uniformily colored, but have the entire second interspace, the base
of the third and the entire apex of the elytra, pale yellowish-testaceous,
the entii-e sutural or first interspace black. The specimens are all
colored alike, that I have seen.

Occurs at Salt Lake, Fort Simpson and Oregon.

A. occidentalis, n. sp. — Oblong, black, shining. Head smooth, with very
few and fine punctures anteriorly; gense very obtuse, not prominent. Thorax
broader than long, sides moderately rounded and distinctly margined, base
feebly bisinuate and margined on each side of the middle; disc convex, smooth
and with few coarse punctures toward the side and base, and no fine punctures
Elytra robust, sub-truncate at apex, one-fourth longer than the thorax ; uni-
formly fuscous, but more commonly yellowish-testaceous, with the middle por-
tion of each fuscous ; surface distinctly striate, strise distantly punctured, be-
coming obsolete toward apex, interstices flat, almost entirely impunctured.
Beneath black, coarsely not densely punctured, and sparsely pubescent. Legs
ferruginous-brown. Antennje rufous, club dark. Pygidium exposed, moder-
ately convex, coarsely and rather densely punctured. Anterior tibise with
outer edge above upper tooth usually simple, rather sub-crenulate. Sexual
characters as in hyperboreas. Length .32 inch ; 8 mm.

Easily distinguished from all our species by the sub-truncate elytra
the exposed pygidium, the almost entirely impuuctured head, with the
sides of the gense very slightly prominent. The color of the elytra
varies from a uuiform brownish to those in which the sutural, apical

AMERICAN COLEOPTERA. 115

and basal margins are yellowish-testaceous, the remaining portion
brownish, but with lines indicating the striae paler. Occasionally the
pygidium is not prominent, in this case the sub-truncation of the ely-
tra is rendered still more evident.

Occurs from Montana westward to Oregon.

Section II contains the bulk of our species, usually of moderate or
small size, several of them however large, rivaling those of the preced-
ing group in length, although never very robust, but few of them are
notably convex, many depressed. Many curious sexual characters have
been noticed, and will be adverted to in their proper places. The
scutellum is small, triangular, never longer than one-eighth or one-
tenth of the elytra.

As the species are numerous, they may, for convenience, be divided,
in accordance with the suggestions of Erichsou, into groups.

Apex of hind tibiae fringed with short equal spiuules.
Thorax distinctly margined at base.
Head more or less tuberculate.
Mesosternum not carinate.

Clypcus sub-quadridentate Group C.

Clypeus sub-emarginate.

Sides of thorax, near hind angles, distinctly sinuate Group D.

Sides of thorax rounded, not sinuate behind Group E.

Mesosternum distinctly but slightly carinate Group F.

Head not tuberculate; clypeus emarginate and bidenticulate Group G.

Thorax not margined at base; head tuberculate; sides of scutelluni

emarginate Group H.

Apex of hind tibice fringed with unequal sijinules.
Head distinctly tuberculate.
Elytra yellow, with black spots ; base of thorax margined ; hind

tibije stout Group I.

Head not tuberculate.
Thorax not sinuate at sides near base.

Elytra strigose: opaque black ; base of thorax margined ; hind

tibiae slender Group K.

Elytra glabrous, shining; tase of thorax more or less mar-
gined Group L.

Elytra pubescent, sub-opaque Group M.

Thorax distinctly sinuate on-the sides near hind angles.

Clypeus denticulate; elytra oblong Group N.

Clypeus emarginate; elytra oval Group 0.

In using the above table the student must, at all times, be careful
that the specimens are perfect, that is, that the spinnles at the tips of
the tibia) are not worn or accidentally reduced to an equal size, or that
the long hairs fringing the sides of the tibiic do not, by crossing the

116 GEORGE II. HORN, M. D.

field of vision, deceive into the belief tliat the spinules are unequal.
In old specimens of those species in which the clypeus is denticulatej
the teeth are apt to be worn down as also the spurs of the tibiae, and
the large teeth of the anterior tibiae. In those that are pubescent,
various accidental causes may remove the hairs, and experience alone
here, as well as in the previously noted accidents, must be our
guide.

Group C contains but one species. Form robust, clypeus rather
deeply emarginate at middle, bounded by a tooth on each side and
with another smaller, more acute tooth at one-third the distance to-
ward the genae. Front distinctly trituberculate along the line of the
frontal suture. Prothorax with base distinctly margined. Scutellum
small, elongate oval. Posterior tibial apical spinules short, equal.
First joint of hind tarsi shorter than the upper spur, equalling the
two following. Anterior tibiae above the upper tooth strongly
serrate.

A. denticulatus, Hald. Journ. Acad. Ser, II, vol. i, p. 104. — Oblong, piceous,
shining. Head densely and coarsely punctured. Thorax convex, -with sparsely
placed coarse punctures, denser however at the sides; anterior angles paler.
Elytra broader behind the middle, very convex and obtuse behind, deeply
striate, striae coarsely and closely punctured, interspaces feebly convex, with
very distant fine punctures, sutural interspace brownish-ferruginous. Body
beneath ferruginous, middle and hind femora and metasternum piceous. No
sexual characters have been noticed. Length .30 inch; 7.5 mm.

The entire margin of the body is fimbriate with yellowish hairs,
also the under surface and legs, the hairs of the hind tibise are especi-
ally long, giving the species the air of an uEgialia.

Occurs along the eastern base of the Rocky Mountains, from Bitter
Root Valley to New Mexico.

Group I) contains one species introduced from Europe, and now
gradually spreading over our country. Head distinctly tuberculate,
front broadly rounded, feebly emarginate at middle and slightly sinu-
ate in front of the genae, which are obtusely rounded and not promi-
nent. Thorax margined at base, sides sinuate near hind angle. First
joint of hind tarsi shorter than upper spur and slightly longer than
the two following joints. Outer edge of anterior tibiae with several
rather coarse punctures above the upper large tooth.

Group E comprises species of variable form, color and size. Tbe
bead is distinctly tuberculate, clypeus sometimes bemibexap;onal or

tured, as far as I have had the opportunity of examining. The pro-
minence of the angles on each side of the clypeal emargination is sub-
ject to vary, and they may become rounded. In this case, the evi-
dences of age are always apparent, and the acuteness of the edge is al-
ways obliterated as well as tbe prominence of the angles desf.royed.

A very widely diffused species, occuring over our entire territory
from Canada to Texas, and westward to the eastern base of the Rocky
Mountains, and presenting slight varieties when specimens from re-
mote regions are compared singly, but vanishing when a series em-
bracing our whole country is examined. The following description
will suffice to render it recognisable among our other species.

Oblong, convex, shining, rufo-piceous or piceous, never entirely black, usu-
ally with the sides and always with the apices of elytra paler than the disc.
Front hemihexagonal, clypeus distinctly emarginate at middle, on each side of
which the edge is obtusely prominent and not broadly rounded; surface in
front rugosely punctured, behind more finely punctulate and distinctlj' but
slightly trituberculate. Thorax punctured, finely on the disc more coarsely
and densely toward the sides. Elytra moderately deeply striate, and with
coarse rather approximate punctures: interstices moderately convex, smooth.

inipunotured. Body beneoth variable in color, as tbe upper surface, but paler,
legs rufous. Length .18 — .22 inch; 4.5 — 5.5 nun.

I have united with ruricola the species described by Haldeman and
Harold, for the reason that I have been unable to detect any character
that is of sufficient moment to define their difference. A. axrclianus,
Harold, is an exact reproduction of Haldeman'sr?<r?«s-, and differs only
from the types found in Pennsylvania in its ratlier larger size, darker
color and (hardly appreciably) less densely punctured head and thorax.
To be convinced that these are of no value, it is only necessary to con-
sult a large series, or to place these differences parallel with those
which are well known to occur in the still more widely diffused (jran-
arius.

The females are much more rare than the males, and have the an-
gles on each side of the clypeal emargination more prominent and
acute.

testaceous, with a broad lateral margin, scutellar space and broad sutural band
darker. Head distinctly trituuberculate, anteriorly. coarsely punctured and ru-
gose, prosteriorly punctured; clypeus feebly emarginate, with the angles on
each side broadly rounded and brownish-ferruginous. Thorax moderately
convex, smooth, with entire surface punctured with fine and coarse punctures,
more densely placed near the sides, lateral margin dark ferruginous. El^'tra
feebly striate, distinctly punctured ; interstices nearly flat, slightly punctulate.
Body beneath piceous, mesosternum strigose, legs rufo-testaceus. Length .22

A species easily recognisable by the color of elytra, and sculpture of
mesosternum.

Occurs in Russian America. Typical specimens from the hand of

rounded, feebly prominent. Thorax strongly convex, sparsely and coarsely
punctured; base distinctly margined. Elytra striate, striae not coarsely but
approximately punctured ; interstices flat, very finely alutaceous, more coarsely
toward apex, which is sub-opaqu9. Beneath black, legs pieeous-black, an-
tennse rufous, club darker. Length .20 inch; 5 mm.

Type from San Francisco, others from Russian America.

The color of this species is very black, and may easily be recognised
by the characters given in the table. The mesosternum is strigose.
The elytral interspaces, especially toward the apex, exhibit decided
traces of an alutaceous sculpture, which renders the apices of the ely-
tra decidedly opaque. The specimens from Russian America have the
elytral striae scarcely as well defined, and the interstices are apparently
flatter. These slight differences hardly seem to warrant the separa-
tion of them as distinct species.

Group F contains but two species, differing from those of the pre-
ceding group by the mesosternum being distinctly carinate between
the middle coxa3.

and very abundant wherever it occurs. Specimens have lately been
received from various parts of maritime California. Length .16 — .25
inch; 4 — 6 mm.

So much space has already been given to the description of this
species that it is not deemed advisable to add anything further, the
student is referred to that of Harold above cited.

This species is readily known by the few characters above given.

AMERICAN COLEOPTERA. 121

It occurs rather abundantly from the ^liddle States to Kansas, those
from the western region being smaller.

Group G contains a single species, differing from all our species in
appearance, in having tlie thorax notably narrower behind and the
hind angles broadly rounded. The elytra are oval, narrower at base
than at middle, at the bases of the thorax and elytra apparently more
distant than in any other of our species. The head is moderately con-
vex, not tuberculate, clypeus rather deeply emarginate and on each
side elevated into a very distinct acute tooth. The base (if thorax is
distinctly margined, the mesosternum feebly carinate, and the anterior
tibial not serrate above the upper tooth. First joint of hind tarsi
slightly longer than the second and third together. No remarkable
sexual characters have been noticed.

A. nevadensis, n. sp. — Moderately elongate, black, shining. Head moder-
ately convex, not tuberculate, rugose, especially in front and at sides, broadly
rounded in front, gense moderately prominent; clypeus emarginate and on
each side distinctly denticulate. Thorax rounded and narrower behind, hind
angles broadly rounded, base broadly rounded and distinctly margined ; sur-
face finely not densely punctured, with coarser punctures intermixed, more
numerous at the sides. Elytra oval, humeri rounded, surfaced' istinctly striate,
striae feebly punctured at base, more distinctly toward apex, interstices feebly
convex and sparsely punctulate. Body beneath black, mesosternum in front
of coxse coasely punctured or cribrose, between coxae carinate. Legs rufo-
piceous, antennae luteous. Length .22 — .30 inch; 5.5 — 7.5 mm.

This species is readily known by the characters given. The wings
are very feebly developed. It varies in color from black to brown. In
some the elytral stria) are fainter, the interspaces flatter and impunc-
tured.

Specimens were collected inXevadaby Mr. Gabb ; others have been
sent by Mr. Henry I^dwards. probably from the same region.

Group H contains two small elongate species characterised by the
absence of the basal prothoracic line. The gena5 are very feebly pro-
minent.

west as New Mexico.

A. vestiarius, n. sp.— Elongate, piceous-black; margin of head, sides of
thorax, sutural and lateral margins of elytra piceo-rufous, shining. Head
distinctly tuberculate, middle tubercle elevated into a very short horn, surface
sparsely punctured at the margins, more densely on the front; clypeus dis-
tantly emarginate, gense not jarominent. Thorax broader than long, convex.

apparently narrower in fmnt, coarsely but sparsely punctured, with few finer
punctures intermixed; sides moderately rounded, base not margined. Elytra
moderately deeply striate, stria3 closely punctured at base, scarcely punctured
at apex, insterstiees moderately convex, sparsely punetulate at apex only.
Body beneath piceo-rutbus ; legs rufous. Mesosternum between the coxfc dis-
tinctly carinate, in front strigose. Antennre testaceous. Length .16 inch;

Easily known from lividus by its color, coarsely punctured and more
convex thorax.

Specimens collected near St. Augustines, Florida, and presented to
me by Mr. Levi Taylor.

Group I contains but few species easily known among the others
by the yellow elytra with variously arranged black spots, and by the
tuberculate head. All have the thorax distinctly margined along the
basal line. The hind tibiiie are rather stout and fringed at apex, with
unequal spinules. The hind tarsi have the first joint equal in length
to the longer tibial spur. The sexual characters may be found in the
more strongly tuberculate head, and more coarsely punctured
thorax.

Our species are as follows :

Clypeus distinctly angulate on each side of emargination serval.

Clypeus broadly rounded on each side.

Elytra with lateral black vitta inquinatus.

Elytra with black spots only, no lateral vitta.

,18 — .22 inch ; California. Elytra with the inner series of

strise joining the outer series pardalis.

.28 inch. Canada and Maine. Elytra with the three inner
strise nearly equal, not confluent with the outer
three leopardus.

A. serval, Say, Bost. Journ. i, 1837, p. 1T7 ; Am. Ent. Ed. Lee. ii, 651.

A pretty little species easily known by the clypeus being distinctly angulate
or broadly denticulate on each side of the emargination. The head is very
coarsely punctured, and toward the sides and front rugose, gense not promi-
nent. Thorax moderately convex, sides feebly rounded, surface coarsely punc-
tured, rather more densely toward the sides, less coarsely and densely in the
female. Elytra pale yellowish as in inquinatus, with the lateral and apical
margins reddish, and with black spots arranged as follows; a small spot at
base of fifth interspace, another on the fourth slightly in front of middle and
one slightly behind the latter and usually confluent with it on the third inter-
space, sometimes extending on the second, a sinuous band composed of conflu-
ent spots on the second, third, fourth and fifth interspaces about one-fourth
from the apex, lateral stripe occupying portions of the seventh, eighth and
ninth interspaces, gradually fading into the rufous margin. Body beneath
brownish, legs paler. Length .18 inch; 4.5 mm.

The rufous marginal space becomes broader at apex extending
about a sixth of the length of the elytra, and usually darker at its an-

terior portion in the second and third interspaces, so that there appear
to be two additional bhick spots behind the sinuous transverse band
above mentioned. The frontal margin is rufous, also the anterior an-
gles and frequently the sides of the thorax.

This species is by no means common in collections, two species only
are known to me, one from Pennsylvania and another from the Indian
Territory, near Fort Cobb, showing at least a wide distribution.

This species, like (/ranarius, appears to have become almost cosmo-
politan, and is abundant over our entire country east of the llocky
Mountains. Much of the synonymy of the European authors has
been omitted as unnecessary to the object of the present essay.

From all our species which have the clypeus on each side of the
emargination rounded, Inqulnatus may be known by the broad lateral
black stripe. The sides and apex are not rufous as in serval. The
black spots are, a basal spot at base of fifth interspace, one slightly be-
hind this, irregular in outline, occupying portions of the fourth, third
and second; behind the middle a sinuous transverse band joining the
lateral stripe and extending to the third stria. The head is usually
black, the anterior angle of the thorax rufous.

This species is slightly longer than serval, and occurs abundantly
in almost every portion of our country and Europe.

A. pardalis, Lee. Pacif. R. R. Rep. App. i, p. 41, 1857. — Head black, with ru-
fous front and sides, coarsely punctured and rugose near the margins. Thorax
more convex than in inquinatus, sides broadly rounded and rufous orrufo-testa-
ceous, surface coarsely but stiarsely punctured, with finer punctures between.
Elytra somewhat bmader behind the middle, more convex than in inquinatus,
pnd more obtuse behind, faintly striate, strije distinctly but coarsely and closely
punctured, pale yellowish-testaceous, with black spots arranged as follows; at
base of fifth interspace, another slightly behind the scutellum on second and
third, another behind this on fourth, and another about the middle on the
second and third, a sigmoid transverse patch on the sixth, fifth and fourth, and
three lateral elongate spots on the seventh, eighth and seventh again. Body
beneath brownish, abdomen, legs and parts of mouth rufo-testaceous. Length
.22 inch ; 5.5 ram.

The series of spots on the disc of elytra are at times confluent, so
that they form nearly a semi-circle on each elytron, the lateral spots
frequently join and form an irregular stripe, but is always irregular
and indicates its origin in the confluence of smaller spots, while the
broad stripe of inquinafiiA^ extends along the greater part of two or
three interspaces. It may al.><o be known by the sides of the head, in
front of the gena3, being slightly sinuous.

124 GEORGE n. HORN, M. D.

Abuudant along the Pacific slope from San Francisco to Van-
couver.

A. leopardus, n. sp, — Similar in form to inquinatus, but large'' more robust-
Head coarsely not densely punctured, not rugose in front, sides rufous. Thorax
moderately convex, surface rather densely and coarsely punctured with finer
punctures intermixed, sides feebly rounded and broadly rufous. Elytra slightly
broader behind the middle, moderately deeply striate, with j^unctures not very
closely placed, interspaces feebly convex, more distinctly toward the ajiex,
very sparsely punctulate ; color yellowish, slightly reddish in more recent
specimens, and with black spots, a small spot at base of fifth interval, one
slightly in front of middle on the fifth and fourth, usually joining, another
slightly behind it on the second and third, a sinuous band at apical fourth on
intersj>aces five, four, three and two, usually extending foward along the
second interval, joining the spot in front, usually a small black spot slightly
behind the humeral angle on the seventh and eighth intervals. Body beneath
piceous. legs and parts of mouth testaceous. Length .28 inch ; 7 mm.

Differs from all our species of the group by the greater convexity
of the elytra! interspaces. The striae of the inner series extend near-
ly to apex of elytra, are parallel and not confluent with those of the
outer series; the fifth and sixth stria? alone join. This arrangement
of the striiie is the rule in Group B, and only rarely occurs in any uf
the following groups.

Maine and Eastern Canada.

Group K contains but few species easily known by thier surface
being entirely opaque. The head and thorax is always densely and
rather coarsely punctured and the elytra faintly striate, with inter-
spaces flat, either finely longitudinally wrinkled, or muricately punc-
tured. The thorax is distinctly margined at base. The hind tibitB
with the upper oblique line of spinules almost entirely obliterated.
The first joint of the hind tarsi is not as long as the two following to-
gether, although equalling' the upper spur.

Our species are distinguished as follows.

Clypeus on each side of emargination with an acute tooth lutulentus.

Clypeus on each side of emargination rounded.

Mesosternum fiat stupidus.

Mesosternum carinate between the coxae lentus.

A. lutulentus, Ilald. Proc. Acad, i, 1842, p. 304 ; Journ. Acad. Sor. ii, vol. 1,

acute prominent tooth, distinctly sinuate in front of the gense. Head coarsely,
densely and very equally punctured, moderately convex and with very faint
traces of the three tubercles, so prominent in the preceding group. Thorax
moderately convex, sides feebly rounded, surface very densely and coarsely
punctured. Elytra elongate oval, moderately convex, feebly striate, strife with
traces of distant punctures; interspaces flat, very finely longitudually wrinkled
and sub-quadrate. And with very minute and fine erect hairs, scarcely to be

i?cen except when viewed between the lens and a strong light. Body beneath
black,, shining, legs piceous-black. Mesosternuin flat, not carinate. Length
.28 — ..".0 inch ; 7 — 7.5 mm.

In all the specimens before me the apices of the elytra are .slightly pro-
longed and each rounded at tip, they are probably all males.

Occurs in the Middle and upper Southern States.

A. stupidus, n. sp. — Oblong, robust, black, sub-opaque. Head coarsely and
moderately densely punctured less densely at the sides and anterior margin.
Clypeus emarginate at middle and round on each side and with a very faint
sinuatiou in front of genoe. Thorax moderately convex, sides rounded, surface
densely punctured but less coarsely and densely than in lutulentu.i, base with c c

entire marginal line. Elytra moderately convex, sides sub-parallel, moder- , /

ately striate with scnreely any traces at apex, and rugose and muricate becom-
ing smoother toward the apices of the elytra. Body beneath black, shining,
legs piceous. Mesosternum not carinate. Length .20 — .22 inch; 5 — 5.5 mm.

In one specimen before me the margin of the elytra uear the apex
is slightly sinuate ( 9 ?) and slightly more prolonged than in two
others ( S '■) iu which the margin is entire and the apex more obtuse.
This species is less opaque than lutulcntus and the minute hairs rather
more evident and apparently greyish.

The only specimens known are from Georgia.

A. lentus, n. sp. — Elongate oval, slightly depressed, brownish ferruginous,
sub-ojiaque. Head coarsely but sparsely punctured, less densely at the sides,
and in front nearly smooth. Clypeus feebly emarginate, rounded on each side
and not sinuate in front of gense. Thora.x moderately convex, sides feebly
rounded, base distinctly margined, surface rather coarsely and evenly punc-
tured. Elytra elongate oval, moderately deeply striate with scarcely any
traces of punctures in the strife, interspaces flat transversely wrinkled and
muricate and with few very minute hairs. Body beneath shining ferruginous.
Mesosternum, between the coxse, distinctly carinate. Length .15 inch;
4 mm.

The elytral stria) of this species are equally deep at base and apex,
the inner stride being long, and extending nearly to apical mar-
gin and not confluent with the outer series of strise. The margin
near apex is very faintly sinuate in both .specimens before me. It
may be possible that the color of this .species is due to immaturity, it
is however less oparjue than either of the preceding and may readily
be known by the carinate nicstisternum.
Pennsylvania and Georgia; rare.

Group L contains species agreeing in having the elytra entirely
glabrous and shining and without any traces of pubescence. They
vary much in other characters so that were it deemed advisable, several
groups could be constructed as ni.ay be seen fr<jm the following table,
where may be found species with slender and stout hind tibi;x! and

given in the tables. It differs moreover from stercorosna in having the
color of the elytra uniform which in the latter species is always clouded.
Occurs from the ^liddle States to Texas.

A. stercorosus. Mels. Proc. Acad, ii, 1S44, p. 13(1.

Similar in form and color to ruhcolus but less robust. Head more
densely punctured. Thorax finely punctured on the disc with coarse
punctures toward the sides. Elytra ferruginous with darker clouding,
not deeply striate, stri;x! more distinctly punctured than in the pre-
ceding species. IjCngth .14 — .10 inch; 3.5 — 4 mm.

Xot rare in the Middle States and southward.

A. militaris, Lee. Proc. Acad. 1858, p. 65.— Elongate, ferruginous, shining.
Head rather coarsely granulose, clypeus emarginate at middle and on each side
an acute prominent tooth. Thorax rather coarsely not densely punctured,

moderately rounded, base distinctly margined. Elytra parallel, faintly striate
striae finely punctured; interspaces flat, coarsely punctured. Mesosternum dis-
tinctly carinate. Length .20 — .24 inch; 5 — 6 mm.

Notwithstanding the original description, the mesosternum will be
found to be distinctly carinate. When examined with very high
power the elytral interspaces may be seen to be very minutely and
densely punctulate. One specimen before me $ has the spur of the
anterior tibia slender and acute, two others % show no traces what-
ever of any .spur. The anterior tibiae are normal in their construc-
tion and not truncate as in Coj)fo(hirus.

Three specimens San Diego, Cal.

A. rubiginosus, n. sp. — Elongate, ferruginous, shining. Head densely not
coarsely punctured; clypeus emarginate at middle, angnlate on each side of
emargination. Thorax moderately convex, densely not coarsely punctured,
sides moderately rounded, base distinctly margined. Elytra moderately con-
vex, sides slightly rounded rather deeply striate, striae closely punctured, inter-
spaces feebly convex, densely punctulate. Body beneath rufous, mesosternum
flat. Length .22 inch; 5.5 mm.

Male. — Spur of anterior tibia slender, strongly curved backwards, inner spur
of middle tibia slender and short.

Closely resembling milifaris differing in the sexual characters, and
by the front being nearly angulate and not bidcntate, also by the flat
not carinate mesosternum.

One specimen from Camp Grant, on San Pedro River, Arizona.

Occurs in North Carolina.

A. consentaneus, Lee. Agass. Lake Super, p. 225. — Moderately elonsjate,
shining, yellowish testaceous. Head sparsely punctured, more densely at the
sides and in front ; clypeus feebly eraarginate and on each side broadly rounded,
Thorax moilerately convex, disc feebly punctured, more densely at the sides.
Elytra elongate oval, moderately convex, rather deeply striate, striee serrately
punctured, interspaces moderately convex, sparsely and finely punetulate.
Beneath pale yellowish testaceous. Hind tibise slender. Anterior tibise norm-
ally tridentate. Length .20 inch : 5 mm.

The thorax and head are usually darker than the elytra, the disc of
this foi'mer being slightly clouded with rufous. Resembles superfici-
ally j[>7ioZer<'oM7e6', the differences will be given under that species.

Occurs in Canada, Missouri and Kansas, but is not common.

A. politus, n. sp. — Oblong, smooth, shining, pale ferruginous and bi'oadly
rounded on each side. Thorax moderately convex, smooth, shining and with
few very coarse punctures as the sides; sides moderately rounded, hind angles
broadly rounded, base not margined. Elytra moderately convex, shining,
faintly striate, strioe very finely punctured, intersjiaces flat, smooth, impuue-
tured. Body beneath pale ferruginous, smooth shining. Hind tibise stout.
Spur of anterior tibia of male broad spatulate and truncate at tip. Length .32
inch : 8 mm.

The lateral margin of the thorax is more distinctly reflexed than in
either of the following species and more broadly at the basal angle so
that immediately in front of the hind angle the thorax is slightly con-
cave. It is remarkable that one of the characters of the males of
Group B should reappear in this species. The hind tarsi are slender
and the first joint nearly as long as the three following.

The unique in my cabinet is from Texas.

A. rubidus, Lee. Pacif. E. R. Rep. App. i, p. 41. — Length ..30 — .35 inch ; 7.5 —

These two species resemble each other closely but may be readily
distinguished by the thorax of the former being very coarsely but
sparsely punctured over its entire surface while the latter has punc-
tures only at the sides. The clypeus of )-itLidiis is also more distinctly
angulate on each side of the euuirgination. Both species are shining
ferruginous or brown. Elytra rather deeply striate and finely serrate-
ly punctured. Interspaces feebly convex and nearly smooth. Inner

Specimens are from Georgia, Kansas and Nebraska.

A. subseneus, Lee. Pacif. R. R. Rep. 1857, App. i,p. 41. — Oblong, sub-parallel,
black, with a?ncous lustre. Head coarsely punctured more densely toward the
sides; elypeus feebly eniarginate and rounded on each side; genre feebly pro-
minent. Thorax very convex, transversely coarsely punctured, more densely
toward the sides; sides nearly straight, hind angles nearly rectangular, base dis-
tinctly margined. Elytra oblong, robust, sides sub-parallel, faintly striate, strias
finely punctured, interspaces flat, very moderately and sparsely punctulate and
alternately distinctly alutaceous. Body beneath black, legs piceous, hind
tibiae rather slemier. Length .18 — .20 inch , 4.5 — 5 mm.

The elytra are not uniformly black but have a broad yellow vitta on
each occupying the second, third and fourth interspaces, usually irregu-
lar on tlie outer side and extending to the tip of the elytra. Other
specimens have the alternate interspaces yellow, the bands being more
or less interrupted and not attaining the apex, and one specimen has
the second and fourth interspaces yellow, united near apex by an oval
spot, and smaller spots at bases of second to sixth interspaces. The
apices of the elytra are usually finely alutaceous and the epipleura) in
several specimens rufous.

Occurs at San Francisco, Cal.

A. alternatus, n. sp. — Oblong, black, shining. Head coarsely not densely punc-
tures except at sides and in front. Clypeus feebly emarginate at middle, broadly
rounded on each side and very slightly sinuate in front of the moderately pro-
minent gence. Thorax less convex than in subcsneus, sides moderately rounded,
base faintly margined near the sides, not margined at middle, surface coarsely
punctured, coarser and more dense at the sides. Elytra oblong parallel, moder-
ately convex, striate, strife coarsely punctured, interspaces flat, alternately yel-
low, and coarsely punctured more densely toward the sides and apex. Body
beneath black, legs piceous, hind tibite slender. Length .18 — .24 inch ; 4.5 — 6
mm.

Varies also in color as in siibseneun, one specimen before me has
the bases of intervals two to six yellow, and the second, fourth and six
intervals yellow to apex, another has only the second and fourth, while
still another is apparently entirely black, but a strong light shows the
alternate intervals very distinctly paler than tlie others. It resembles
subseneus in form, but may easily hi kncjwn by the absence of metallic
lustre and the rather coarse punctures of the elytra.

Several specimens from Bitter Root Valley, and one from an un-
known region of California.

A. terminalis, Say, Journ. Acad, iii, 182.'?, p. 21.3. — Elongate oval, moderately

For the unique in my cabinet, I am indebted to Mr. James Ridings,
who found them rather abundantly in Colorado.

This species recalls the form oi: ui-si)ius.

clypeus emarginate and rather strongly angulate on each side. Thorax moiler-
ately convex, sides feebly rounded, surface coarsely punctured with finer punc-
tures intermixed, base distinctly margined. Elytra oblong, rather deeply
striate, striae finely punctured, interspaces moderately convex and punctulate.
Pro- and mesosternum piceous, metasternum, abdomen and legs yellowish.
Length .18— .24 inch ; 4..5— 6 mm.

The elytra are usually black or piceous, but in several specimens be-
fore me they are dark ferruginous^with the alternate intervals (2 — 4 —
6) showing paler rounded spots. The species may be easily known
from any in our fauna by its dark color above and yellow legs and ab-
domen.

Occurs from Canada to Texas.

A. dentiger, Lee. Proc. Acad. 1858, 6'>. — Oblong oval, piceous black, shining.
Head sparsely but coarsely punctured and finely rugose infi'ont; clypeus at
middle truncate and on each side an acute slender tooth, outside of which the
clypeus is rather deeply sinuate. Thorax moderately convex, sparsely but
coarsely punctured on the disc, more densely at the sides, sides feebly rounded
gradually narrower in front, base distinctly margined. Elytra broader behind
the middle, feebly striate, striae distantly punctured, interspaces flat, very
sparsely and finely punctulate. Body beneath piceous. Male. Spur of anterior
tibia slightly arcuate, and hooked at tip; inner spurof middle tibiashort broad
and, deeply emarginate at tip. Female. Unknown. Length .26 inch; 6.5
mm.

This species is easily known in the group by the two slender teeth
of the clypeus. In the preceding species the angulation of the clypeus
is broad at base, the teeth of deatijer are slender.

AMERICAN COLEOrTERA. 131

A. phalerioides, n. sp. — Elongate oval, pale yellowish testaceous, shining.
Head nearly smooth, finely and very sparsely punctulate; ciypeus very feebly
emarginate and broadly rounded on each side. Thorax moderately convex,
sparsely punctured, sides moderatelv rounded, base not margined at middle.
Elytra elongate oval, yellowish testaceous, slightly clouded with fuscous, feebly
striate, strife finely punctured ; interspaces moderately convex, very sparsely
punctulate. Body beneath pale yellowish testaceous, hind tibite slender. An-
terior tibife nearly truucate at apex, teeth obtuse, the upper obsolete, inner edge
slightly sinuous. Length .24 inch; 6 mm.

A curiou.s species resembling consentaneus, in appearance, but may
be easily known by its stouter hind tibia), and by the peculiar confor-
mation of the anterior.

The specimens in our cabinets are from the Middle States, probably
from near the sea coast.

Group >I contains several species with the elytra distinctly pubes-
cent over the entire surface and more opaque than in the preceding
group.

The species in our fauna are as follows :

Elytra luteous with fuscous cloud ; thorax at base margined.

Anterior tibia;, % , strongly sinuate within, spur hooked Walshii.

Anterior tibia;, % , normal, spur broad, truncate femoralis.

Elytra reddish-yellow; thorax not margined at base.

First joint of hind tarsus equalling the last four together rubripennis.

A. femoralis, Say, Journ. Acad, iii, 1823, p. 215. — Oblong, head and thorax
black, shining, elytra luteous with broad fuscous space, sub-opaque and pubes-
cent. Head sparsely punctured, margin very feebly reflexed ; ciypeus feebly
emarginate and rounded on each side.' Thorax moderately convex, very
sparsely punctured, at the sides luteous, sides moderately rounded, base dis-
tinctly margined. Elytra luteous with broad fuscous space varying in extent,
striae moderately deep, serrately punctured, interspaces convex usually coarsely
punctulate especially near the strife. Body beneath piceous, femora pale lute-
ous, tibia; darker. Length .22 — .26 inch ; 5.5 — 0.5 mm.

Male. — Elytra more coarsely punctulate, spur of anterior tibia broad, thick
and truncate at tip.

Female. — Elytra more sparsely punctulate, spur of anterior tibia slender and
acute at tip.

This species resembles consputus, of Europe, but may be known by
the distinct marginal line at base of thorax as well as by the sexual
character of the male. The margin of head is much less distinctly re-
flexed than in the following species and it is this difference alone that
must be relied on to distinguish the female of Wa/shii ivoxn femoralis.
The tibia) are always much darker in color in the latter species than
the femora, while in the former the legs arc of one color. This can
not however be relied upon to separate them by being a character of
comparative, little value from the tendency to variation.

Occurs from Pennsylvania to Kansas. Numerous specitp ens of this
species have been sent me by Dr. Summers from the neighborhood of
St. Louis, where it appears to be common,

A. Walshii, n. sp. — Similar in color, form and general apyieavunce to femoral is
but differing as follows: Head with margin more broadly reflexed, sides of
thorax more broadly luteous, base distinctly margined. Elytra moderately
deeply striate, strise feebly punctured ; interspaces moderately conve.K, very
sparsely or not at all punctulate. Body beneath as infemoralis, tibise less fus-
cous. Length .20 — .24 inch ; 5 — 6 mm.

Male. — Anterior tibise sinuate wiihin, inner apical angle truncate, spur long,
truncate and hooked at tij), upper tooth of outer edge small, becoming obso-
lete.

Female. — Anterior tibise normal, upper tooth small, more distinct, spur slen-
der, acute.

Easily known by the pubescent elytra, and the peculiar sexual
characters. In both these species the pubescence consists of short
yellowish sub-erect hairs, arranged in a row on each side of each inter-
space.

Two specimens, one from Canada and another from Pennsylvania.

The elytra are much more sparsely pubescent than in either of the
two preceding species.

Group N contains a single species in our fauna, easily known by the
unequal spinules of the apex of the hind tibise, the sides of the thorax
distinctly sinuate near the hind angle, and by the sides of the elytra
being parallel and the clypeus denticulate.

sides; clypeus deeply emarginate at middle and acutely dentate on each side.
Thorax broad, moderately convex, coarsely but sparsely puuctured, with finer
punctures intermixed ; sides moderately rounded, sinuate near the hind angles,
base distinctly margined. Elytra parallel, obtuse at tip, not deeply striate,
strise moderately punctured, interspaces flat, finely and sparsely punctulate.
Body beneath piceous, legs black. Length .36 inch; 9 mm.

Male. — Spur of anterior tibire broad, truncate and hooked at tip or feebly em-
arginate ; inner spur of middle tibise short, robust.

Fr.m-tle. — Spur of anterior tibise robust but acute at tip; inner spur of mifldle
tibise robust but longer than in male.

This species occurs from Pennsylvania to Colorado.

Grroup O contains also but one species, readily known by the un-
equal spinules fringing the apex of the hind tibiae, head not tubercu-
latc, thorax distinctly sinuate at the sides near the basal angles, basal
marginal line wide and deep, clypeus emarginate and broadly rounded,
elytra oval, mesosternum between the coxse feebly convex, hind tibiae
stout, first joint of the hind tarsi equal to the three following
united.

A. ovipennis, n. sp. — Oblong, brownish or piceous, moderately shining. Head
not densely nor coarsely punctured; clypeus emarginate at middle, broadly
rounded on each side ; gense prominent. Thorax broader than long, nariower
at base, sides broadly rounded in front, rather deeply sinuate near the hind an-
gles, base broadly rounded, margined line broad, deep, and coarsely punctured ;
surface moderately convex, very coarsely and deeply punctured. Elytra oval,
broadest at middle, convex, rather deeply striate, strife rather finely and dis-
tantly punctured, interspaces moderately convex, very sparsely punctulate.
Body beneath piceous black, legs rufo-piceous. Mesosternum coarsely punc-
tured, between the coXiB convex, sub-carinate. Epipleurse visible from above,

humeral angles consequently dentiform. Length .30 — .34 inch ; 7.5 8.5

mm.

The three specimens before me show no sexual characters anion"-
themselves. The species is one of the most distinct in our fauna and
may readily be distinguished from any Aphodius known to me by the
characters above given.

Found under stones in dry places at Fort Tejon, Cal.

Aphodius cadaverinus, Mann. Bull. Mosc. 1843, ii, 201.
The descrijition of this species (from Russian America) is too short
and uncharacteristic to enable me to define its position.

BY GEO. H. HORN, M. D.

HISTER, Linn.
H. ITlkei, n. sp. — Oblong oval, sides feebly rounded, black, moderately shin-
ing. Front with distinct semicircular line. Thorax convex, sides feebly
rounded, slightly broader behind, margin fimbriate with short hairs; exterior
stria close to margin, entire, inner stria distant, slighily sinuous and more dis-
tant in front. Elytra with three entire dorsal strise, a fourth and fifth apical,
the former being one half and the latter one-third the length of third; sutural
stria abbreviated in front; subhumeral stria extending one-half from apex to
base and close to the first dorsal, gradually diverging and with a short slightly
arcuate extra-humeral stria; oblique humeral stria distinctly impressed. Pyr
gidium and propygidium coarsely punctured, the latter rather more sparsely.
Body beneath black, shining, abdomen fuscous and coarsely strigosely punc-
tured toward the sides ; side pieces of meso- and metasterna with few coarse
punctures. Anterior tibiae bidentate, hind femora and tibiffi stout, the latter
irregularly biseriately spinulose. Length (tijj of suture to anterior margin of
thorax) 20 inch; 5 mm.

This species differs from all our others of group 3, Lee, by its more
elongate form, very obtuse in front, and by the well detiiio^l internal
subhumeral stria with extra-humeral appendage and also by the pre-
sence of the fourth ami fifth dorsal strife. The legs are entirely black,
the hind tibiae robust as in arcuatus and irregularly biseriately spinulose.
This species should be referred to the fourth group of Marseul.

I have named this species in honor of Mr. H. Ulke, of Washington,
by whom it was sent me under the name insfrafiis, which species has
no subhumeral stria. The elytra are colored as in instratus.

Occurs in Nebraska.

H. Arizonae, n. sp. — Oval, moderately convex, black, shining. Antennae
piceo-rufous. Front with distinct semi-circular stria. Thoracic margin sparse-
ly pilose, and witli two entire nearly parallel strife. Elytra rufous and with

innr^ins. nnd quail raiigiilar scutellar spot, black, with threr- entire ilorsal
strife, a trace of a fourth at apex, sutural stria short abbrevated at each extrem-
ity; oblique huniernl stria distinct; subhumeral stria internal, as deep as the
next dorsal and one-half nearer to it than the second, obliterated at humerus
and without arcuate appendage. Propygidium and pygidium coarsely nut
densely punctured. Side pieces of meso-and metasternum cribmse, abdominal
segments at sides coarsely punctured. Anterior tibire bidentate, middle and
posterior tibia; biseriately spinulose, the latter being strongly compressed and
the spinules distantly placed. Length (ant. margin of thorax to tip of suture)
.18 inch ; 4k mm.

Resembles IT. hiplajlatus, Lee., Iq color and size but it is less broadly
oval.

One specimen. Camp Grant, Arizona.

H. Gloveri, n. sp. — Oblong ovate, robust, convex, black, shining. Antennre
piceous, club paler. Front convex, frontal stria obsolete. Thorax with sides
rounded, gradually narrower in front, margin sparsely flavo-fimbriate ; two
lateral entire striae more distant anteriorly, the inner sinuous at its middle;
surface smooth. Elytra with short rather deeply impressed sub-humeral stria,
three entire dorsals with distant punctures near their apices; fourth and fifth
very short, apical; sutural abbreviated in front. Propygidium and pvgidium
coarsely puuctured, the latter more densely. Inflexed portion of elytra exca-
vate, epipleurfe bistriate. Mesosternum and metasternum smooth, side pieces
coarsely but distantly punctured. Anterior tibiae bidentate, middle biseriately
spinulose, posterior thickened, very irregularly spinulose. Length (from apex
of thorax to end of suture) .24 inch; 6 mm.

A very distinct species from any known to me. The sub-humeral
stria is short, its apical portion being replaced by a few moderately
large punctures. In front of the fourth and fifth striae similar punc-
tures are seen. Its color is entirely black.

This species must be referred to Group 3, Lee. (Proc. Acad. 1852,
p. 38) and Group 5, A., Marseul.

For the unique in my cabinet, I am indebted to Mr. Townend
Glover, of the Agricultural Department, to whom I with pleasure de-
dicate it. It was found near Fort Cobb, Indian Territory.

H. militaris, n. sp. — Oblong oval, sides feebly rounded, black shining, elytra
red, with scutellar spot, apical and middle of lateral margin black. Front
slightly concave, with distinct semicircular line. Sides of the thorax very
feebly rounded, and slightly narrower, in front, margin glabrous. Inter-
nal stria entire, straight, external stria short. Elytra feebly convex with three
entire dorsal striae and short fourth and fifth striae at apex, sutural stria with
basal fourth obliterated; oblique humeral stria short, feebly impressed. Pygi-
dium and propygidium densely punctured. Anterior tibiae sub-tridcntate, pos-
terior tibiae slender, biseriately spinulose. Epipleurse bistriate. Antennal
fossae shallow. Body beneath and legs black. Length (apex of suture to anter.
margin of thorax) .18 inch ; 4.5 mm.

Notwithstanding the sub-tridentate tibioe and glabrous thoracic

W6 GEORGE H. HORN, M. D.

margin (the lafctei- may be accidental) I retain this species in G-roup
3, Leconte, on account of the very shallow antennal fossae. It differs
from all our species to which it is allied by the outer marginal thor-
acic stria being short and scarcely extending one third from the an-
terior angle toward the basal margin. The elytra have no trace of
subhumeral stria, the first three dorsals are entire, the next two short,
the fourth having the anterior half obliterated, the fifth the anterior
two-thirds. At the base opposite the fifth stria, on one elytron, are
two punctures and on the other a very short stria.

This species must be referred to Marseul's Group 7.

One specimen, somewhat injured, collected at Fort Yuma, Cali-
fornia.

The description of our species of Group 3, Lee, are widely scattered
and as those with red elyti-a resemble each other closely in description,
the following table is offered as a guide to our students of this family.
The arrangement of Marseul is so widely different from that of Dr.
Leconte that our nine species are spread in four groups. The num-
bers in parenthesis indicate the latter groups.

Marginal stria of thorax entire.
Elytra without subhumeral stria.

Hind tibiae compressed, biseriately spinulose, spinules

distant; margin of thorax sparsely fimbriate biplagiatus, Lee. (7).

Hind tibiae stouter, spinules very irregularly biseriate ;

margin of thorax fimbriate with long hairs sellatus, Lee. (7).

Elytra with distinct subhumeral stria.

Subhumeral stria internal, and with humeral arcuate
appendage.
Form broadly oval; femora rufous, hind tibife robust,

fourth dorsal stria very short or wanting arcuatus, Say, (4).

Form oblong; femora piceous ; fourth dorsal stria ex-
tending three fourth to base Ulkei, Horn, (4).

Sub-humeral stria internal, not appejidiculate at hu-
merus.
Outer edge of anterior tibia not dentate, color entire-
ly black laevipes, Er. (2).

Outer edge of anterior tibia bidentate ; elytra in

great part red Arizonae, Horn, (2).

Sub-humeral stria external, short, visible only at hu-
merus.

Body entirely black, form robust, convex Gloveri, Horn, (5).

Elytra red in great part, less convex, broader instratus, Lee. (5).

Marginal stria of thorax short, visible only in front militaris, Horn, (7).

The above mentioned species have the thoracic margin more or less
fimbriate, and with the exception of laevipes the anterior tibiae are
bidentate. Two are entirely black the others have red elytra with a

AMERICAN COLEOPTERA. 137

scutellar black spot anJ the sides, apex, and base usually margiued
with black.

HET^RIUS, Erichs.
H. californicus, n. sp. — Broadly ovate, convex, reddish-brown, shining.
Front concave, margin elevated, rather coarsely punctured and hairy. Thorax
with a deep oblique sulcus on each side, margin thick, very convex, and with
a deep impression at middle. Elytra seriately setulose, and with two discal
stripe, of which the outer only is entire, an entire sub-humeral, extending from
base to apex. Pygidium convex, smooth, inferior. Propygidium smooth, con-
vex, vertical. Prosternum comjjressed between the eoxse, broader behind,
emarginate at apex, lobed at base. Mesosternum with middle lobe rounded,
prominent, lateral lobe prolonged, acute, and with deep fossa on each side.
Body beneath paler, smooth, shining. Length .09 inch; 2.25 mm.

The disc of the thorax between the grooves is moderately convex,
rather coarsely punctured and hairy, the margin is very convex and
with a very deep impression at the middle, in front of which the sur-
face is coarsely punctured and hairy, and behind smoother. The
obli((ue sulcus is deeper and broader at base. The sides of thorax are
gradually rounded from base to apex. The prosternal lobe is quite pro-
minent and slightly emarginate at apex. The prosternum between the
coxaj has on each side a finely elevated line.

Thisspecies resembles brunnipcnuia, Lee, and maybe known by the
sides of the thorax being rounded, not oblique, the impression at middle
of margin deeper, the disc punctured and hairy, the elytra broader, and
the strite deeper. In its general form this species is broader and more
convex.

For a single specimen of this species, I acknowledge great indebted-
ness to Mr. James IJehrens, of San Francisco, who has already contri-
buted several uniques of scientific interest to my cabinet.

One specimen from Sonoma, California. Occurs probably with ants
as do our other species of Jhtxriux.

TRIBALUS, Erichs.
T. californicus, n. sp. — Oblong oval, moderately convex, slightly shining.
Ilead coarsely but sparsely punctured, front near eyes elevated. Antennae
frontal, piceo ferruginous, club annulated, truncate and testaceous; an-
tennal fossa at anterior angle of thorax concealed from beneath by a well
developed pectoral plate. Thorax twice as broad at base as long, moderately
convex, sides gradually rounded from base to apex, lateral margin distinctly
reflexed, surface rather coarsely and moderately densely punctured. Elytra
more shining than thorax, moderately convex, and with four slightly elevated
costse of which the outer three are entire, the inner one half the length of ely-
tra, also a marginal ridge becoming inferior at its posterior half, attaining the
apex but fainter at tip, and a sub-marginal fainter ridge of half the length of
the elytra; intervals between costse irregularly sub-biseriately punctured ;
disc of elytra with series of moderately coarse punctures. Mesosternum arcuate

138 GEORGE H. HORN, M. D.

in front, sparsely punctured, side pieces and first abdominal segment coarsely
punctured. Pygidium inflexed, coarsely punctured. Legs piceo rufous. Length
.07 inch; If mm. (Entire length).

Notwithstandin-^ several of the characters above given the species is
placed ia Tri/jalus, from the position of the antennal fossae, the inser-
tion of the antennae and the form of the club. The inflexed pygidium
has an analogue in Isevissimus, Lee. The elytral sculpture is peculiar
and recalls Onthophilus, from which however it differs in its very dis-
tinct and prominent prosternal lobe. The disc of the elytra (the por-
tion between the two inner ridges, shows rows of fine punctures which
show a tendency to become striae. The sutural row is entire and not
striate, the next inner row is striate at base, arched, uniting with the
sixth row which is also striate and extends in form of stria nearly half
the length of the elytra ; the fifth row also becomes slightly striate at
its apical portion. Between the inner short ridge and the next inner
stria are moderate punctures arranged more regularly biseriately than
those between the costae.

An unique specimen of this insect was sent me by Mr. H. Edwards,
of San Francisco, by whom it was collected in the neighborhood of that
city.

ONTHOPHILUS, Leach.
0. Lecontei, n. sp. — Broadly oval, moderately convex, black, shining. Front
coarsely punctured, anteriorly variolose, feebly triangularly elevated and with
a short, faint carina at vertex. Thorax densely and coarsely punctured, nearly
twice as broad at base as long, sides feebly rounded, gradually narrower to the
front, margin smooth, and thiclsened, apex feebly emarginate, base broadlv
rounded; disc with six elevated lines, the central pair attaining the apex, but
not the base of thorax, the next outer abbreviated at each end, the outer costse
stronger, attaining the base and slightly curved outward toward the basal angle.
Elytra scarcely broader than the base of thorax, disc feebly convex and with
seven rather strongly elevated costse, interstices finely bicarinate and with a row
of distant coarse punctures, margin inflexed, sinuous and carinate. Propygi-
dium convex, slightly more elevated along the middle, coarsely punctured.
Pygidium coarsely punctured, oval, oblique. Prosternura coarsely j^unctured,
slightly concave. Mesosternum very coarsely punctured, variolose. Length .16
inch ; 4 mm.

This species is our largest and is more regularly oval and less con-
vex than any other of our species. The head is much less distinctly
triangularly carinate, the converging ridges being almost obsolete in
front; the carina of the vertex is also very faint. The thorax is
broadest at base, gradually narrowing to. apex and with feebly rounded
sides. The outer carina of the disc is much stronger and attains the
basal margin of the thorax. Tlie elytra have seven distinct costae
on the disc without the sutural elevation. Between the costa) the in-

AMERICAN COLEOPTERA. 139

terspaces are feebly bi-carinulute, often interrupted, and between these,
in the centre of the interspace, is a row of Uirge distant punctures.
The elytra are but slightly broader at base than the base of the thorax,
the general form of the insect being thus more nearly a regular oval
than any of our species. The prosternum is coarsely punctured, the
mesosternum still more coarsely.

A single specimen collected by myself at Fort Tejon, Cal.

S. estriatns. Lee. Pacif. R. R. Surv. App. I, p. .36.

Fine large specimens of this species collected by myself in Owen's
Valley, California, enable me give a full description of it. Its position
in the genus is, according to the arrangement of Leconte, in Group 8,
in Marseul, Group YI, a. The head is distinctly margined in front,
the prosternum is bi-striate, the striae approximate and rather strongly
divergent behind. The front has two distinct chevrons bounded by
feebly impressed lines and apt to be indistinct. The species is robust
recalling that of sulci/rons, but more oval. Head sparsely punctured
moderately convex and subopaque. Thorax strongly convex, sides gra-
dually and feebly rounded from base to apex ; disc densely punctured,
more coarsely toward the sides and with two rows, each of four badly
limited smoother patches arranged in a transverse arc with the con-
vexity forward. Elytra densely punctured, each with three moder-
ately well defined round, smooth, patches arranged in an oblique row,
the outer at the humerus, the middle smaller within and slightly be-
hind the first, the inner larger than the last near the suture and in
front of middle ; a narrow apical margin is also smooth. Toward the
sides are two obsolete stria), the inner one at the inner edge of the
humeral space extending nearly to the apex, the outer stria interrupted
by the humeral space and shorter than the first. The body beneath is
much less densely punctured than the u])por surface. The anterior
tibiae five or six dentate, posterior tibia; biseriately strongly spinulose.
The color of the body is nearly black, opaque and with a ver}' faint
bronzed tinge. Antennas piceous, club rufous. Pygidium densely
punctured at the sides, median space and apex smooth. Length .18 —
.24 inch; 4.5 — 6 mm.

The smaller specimen is in the cabinet of Dr. Ijcconte, and is re-
ported from Oregon, three others of the large size arc from Owen's
Valley, Cul., and were collected by myself. In the Oregon specimen
the lateral striaj are scarcely perceptible, in one of the larger they are
quite distinct, the other two intermediate, forming a gradual series.

140 GEOROE H. HORN, M. D.

S. aequipunctatus, ii.sp. — Oblong oval, moderately convex, black, sub-opaque.
Head densely punctured. Thorax with sides moderately rounded, slightly
narrower in front, anterior angles rounded, surface very densely punctured
and rather more coarsely at the sides. Elj'tra densely and evenly punctured
and with a sutural stria extending from apex two-thirds to the base, and four
dorsal strife parallel and not arcuate at basal end, the inner being two-thirds
the length of the elytra the outer ones gradually longer, humeral stria obliter-
ated at humerus but distinct beyond. Prosternum transversely convex, and
with strife divergent in front terminating in a fossa. Meso- metasternum, abdo-
men and legs coarsely punctured, side pieces of sterna cribrate. Pygidiiim very
convex, coarsely and densely punctured. Anterior tibiae 6-denticulate. Length
(anterior margin of thorax to tip of suture) .14 inch; 3J ram.

This species as the above noted characters exhibit should be placed
ill Gi-roup 6 (Lee. Proc. Acad. 1852, p. 40.) and in Group 2 of
Miirseul's System. It resembles pfinctatissimus, Er. in its sculpture
being however more elongate and less convex and differs from it as
well as our own species in having the inner dorsal stria straight and
not arcuate at basal end. Two of our species of this group have the
entire surface of the body rather densely punctured and without
smooth spaces, insertiis, Lee, and obductus, Lee, these have the inner
dorsal arched at base uniting with the sutural. The margin of the
thorax is not fimbriate.

The specimens of the species have been received from Mr. Jas.
Behrens, collected near San Francisco and sent with a catalogue num-
ber 858.

The two following species having been recently reported within our
faunal limits, short descriptions of each have been given that they may
be known if in the cabinets of any of our students. Full descriptions
with admirable figures may be found in the Monograph of Marseul.

S. cubsecola, Mars. Monog. 1855, p. 467, pi. 18, fig. SB. — Similar in form to S.
fennsyloanicus, but less convex and with the sides of the elytra less rounded
and the sides of the elytra more convergent toward the apex. Head faintly
bronzed, moderately coarsely but not densely punctured, and more sparsely at
apex. Thorax distinctly bronzed, disc smooth, sides finely punctured, punc-
tures narrowly extending along the base. Elytra black, densely and rugosely
punctured, punctures becoming finer and substrigose at apex; seutellar region
less densely punctured, humeri and sides of elytra smoother ; elytral striiie al-
most entirely obliterated; sutural stria entire. Pygidium moderately convex
and with the propygidium rather densely and coarsely punctured. Prosternum
convex and with the strife ascending in front. Mesosternum distinctly punc-
tured. Metasternum smooth at middle, finely punctured at the sides and
coarsely at base. Length (apex of thorax to tip of suture) .20 inch; 5 mm.

The striae of the elytra are indicated merely by the closer approxi-
mation of punctures, the first two attaining nearly the middle, the other

two, very short, the inner united with the sutural by several larger
punctures forming a faint arch. Humeral stria very fine.

One specimen from Key West, agreeing with all the characters
given by Marseul. The species may be found farther north.

S. seneicollis, Mars. Monog. 1855, p. 424, pi. 17, fig. 56. — Very closely resem-
bles S. penn.v/Ivanicus, but may be at once distinguished by the deep groove
around the lateral and apical margins of the pygidium. The entire upper sur-
face is shining, thorax bronze and elytra blue, with a tinge of green. The ely-
tra liave the first and second striss distinctly marked, extending three fourths
of the length of the elytra ; third stria short, basal ; fourth extending to middle
and arching at base to join the sutural; oblique humeral stria distinct but fine,
internal subhumeral obliterated, external very short. Surface of elytra sparse-
Ij"- and finely punctured, apical region with coarser punctures extending for-
ward in lines to meet the striae, and also more numerously along the suture.

rather more densely punctured than the posterior and more densely and
coarsely near the lateral groove. Margin rather coarsely punctured and more
densely in front. Lateral groove not attaining the basai margin. Elytra
sparsely punctured but more densely and coarsely than the thorax. Proster-
num bicanaliculate, median convex portion broadly interrupted and with a
patch of silken hairs. Meso- and metasternum very finely and sparsely punc-
tured, side pieces and first abdominal segment coarsely punctured. Legs

AMERICAN LEPIDOPTERA. 173

Eemarks on Dr. Boisduval's "LEPIDOPTERES DE LA CALIFORNIE."
BY AUG. R. GROTE AND COLEMAN T. ROBINSON.

In the twelfth Volume of the Annales de la Societ6 Entoinologique
dc Belgique, Dr. Boisduval reproduces his first paper on Californiau
Lepidoptera, with additional species and corrections. The Volume
bears the date of 1868 — 1869 ; so that no earlier date can be ascribed
to Dr. Boisduval's paper, with which it commences, than Juhj 1868.

It is necessary to note this, since certain of the species had been
described and illustrated by ourselves in these pages under the date
of January of the same year.

Dr. Boisduval enumerates eighty-four species of Diurnals as found
in California. This number is given without reference to the numer-
ous species described by Mr. Edwards. In foct Dr. Boisduval's ma-
terial is still evidently that collected by M. Lorcjuin, and on which
his first paper was based, and shows no acquaintance with subsequent
discoveries. The error of regarding certain analogous or representa-
tive species from our Western District as identical specifically with
European or Eastern insects, is continued and repeated. California
is credited with a " Thanaos cervatnes,'^ stated however to be "un
peu plus grand que les individus de I'Espagne, and a " Thanaos Jiive-
nalis," conversely " un peu plus petite que les individus de la Greorgie."

In the iEgeriidae three new species are described under the genus
S'isia. The use of the generic name instead of xl^}geria Fahr.^ does
not seem to be warranted by Fabricius' writings, and it should rather
be retained for that genus of Sphingidaeof which S. fuciformis is typ-
ical, and from which Fabricius afterwards separated the species of
^■Egeria.

In the Sphingidae, Marro/hssa thctis, Boisd. Ann. Soc. Ent. Fr.
3 Zieme Ser. Bull. p. xxxii, has been figured and described by our-
selves in these pages as Sesia thetis. The species appears to represent
our Eastern Sesia diffinis in the Western District. Under the name
of Macroi/fosaa Erato, Dr. Boisduval evidently describes Eupro.ser-
pinus phaeton. This small species, which offers many characters in
common with the European Macroglossum stellatarum, nevertheless
seems to us generically distinct. Its synonymy may be recorded as
follows :

TRANS. AMER. E.NT. SOC. (23) OCTOBER, 1870.

174 GROTE & ROBINSON.

Macroglossum phaeton.

Eiiproserpimis phaeton, G. & R. Proe. Eat. Soc. Phil. (N'ov. 1S65).

Macroglossa Erato, Boisd. Ann. Soc. Ent. Bjlgique Vol. XII, p. G5, (1868 —
1869).

Eiiproserpinus phaeton, Gr. & R. Proc. Am. Ent. Soc. (Sept. 1868).
Under Cramer's later specific name, Br. Boisduval records Deilephila
lineata Fahr. spec, as a habitant of California. In our " Sphingidae"
(1865), will be found the full synonymy of the species, with the ex-
planation that Fabricus' first description (1775 and therefore earlier
than Cramer's Vol. 2 — 1779) applies to our Amjrican species and n tt
to the European Deilephila livornica. Further on Boisduval records
the European Deilephila galii as found in California, and considers
our Deilephila chamoenerii Harris^ as the same species. Sphinx se-
quoiae Boisd. and Sphinx strobi Boisd. (the latter possibly not cor-
rectly attributed to California) are then described. These appear to
belong to Hiibner's genus Hyloicus. In the Castniiuae six species are
described under the genus Agarisfa. For all of these species known
to us the generic term Alypia should be used. The first — Alypia
octomaculata — our common species from the Ath^ntic District, is un-
known to us from Califjrnia, and from analogy we are led to regard
Dr. Boisduval's habitat as an error. All the species of this genus
from the Western District of our Continent have the spots on both
pairs of wiug.s above yellow or yellowish, while A. octomaculata, A.
langtonii, etc., have the spots on the secondaries white. This is a
very interesting fact, pertinent to a study of the relationships between
coloration and geographical distribution in insects. Dr. Boisduval de-
scribes Alypia dipsaci G. & /?., Alypia lorquinii G. & R., and Alypia
mariposa, G. and R., previously illustrated by us under the same
specific names. Under the genus Ctenucha Dr. Boisduval describes
two species, C. robinsonii and C. harrisii, apparently belonging to the
second section of the genus. '' 0. rubrnscapus" is C. multifaria*
Walk, spec; while 0. corvina Boisd. p. 71, is a synonym of C.
ochroscapsus, G. tt R.. described by us from specimens in the Ber-
lin Museum. Dr. Boisduval credits Ecpantheria scribjnia to Califor-
nia and describes four species under the genus Ckcltmid, of which C
achaia, is Arctia achaia, previously illustrated in these pages. Arctia
sciurus Boisd. ib. p. 79, is not improbibly Lcucarctia californiea
Packard. Of L. acraea, Dr. Boisduval remarks that it is found as
far south as Central America. The specimens we have seen from
Mexico and Central America, seem to indicate the existence of a dis-

«■ G. & R. List. Lep. N. Am. p. VII (1&68).

AMERICAN LEPIDOPTERA. 175

tinct species in those countries. The most prominent difference was
found in tlie length of the antennvl pectinations in the same sex. The
Xeraeophihi rufula Boi'.-id., foiuiJe 1 on a single individual in indiffer-
ent conservation, is now referred (ib. p 70) to the genus Arctia. We
suspect that this specimen will prove to belong to .\ntarctia punctata
Park. Under its synonym, PhocjjDptern., Dr. Boisduval describes three
Californian species of Halisidota. Of these P. quercus, p. 81, is
Halisidota Edwardsii Pack., P. scdicis, id. is Halisidota californica,
Wil/cr, and P. cinnan^mea, p. 83, is not improbably, H. roseata
Wal/c, or at least an allied species. Under the genus Bombi/x, Dr.
Boisduval enumerates the American species of Glisiocampa. Bomhi/x
//•uteforam, p. 82, is a fresh synonym of C. americaua Harris. We
had not previously heard that it occured in California. Bomhi/x
drupacearum is again a fresh synonym of C. disstria ; and again the
habitat of California, where the species is said suspiciously to be
'•beaucoup plus rare," is new and doubtful. Finally B tmbijx ps^oiul-
one^tstria, p. 82, is C. californica Pack. As Lasiocampa carprinifulia
p. 83, Dr. Boisduval describes a species of Grastropacha from California ;
but we doubt that to this new species the Phalaena iUcifolia of Smith
should be cited. Dr. Packard has shown that Smith may have in-
tended under his erroneous determination either Gr. americaua Harris.,
or G. ferruginea, Pack., from our Atlantic District. The figures of
Abbot& Smith, whatever may be said of their fidelity, are not to be re-
lied on to distinguish such closely allied species. " Saturnia ceannthi,
Behr," is Platysamia californica, and it appears also to be the species
"mentionne" by the name o( •^Eari/aius" by Dr. Boisduval in 1855.
We have as yet seen no description of this species prior to H65.
Pseudohazis eglanterina is cited under Hiibner's genus Telea, of
which our T. polyphenius is typical. Two species of Hepialus, FI .
hectoides, p. 85, and H. californicus ib., afford the first evidence of the
existence of this genus in California we have yet met with. As
Dicramira scolopendriaa, Dr. Bjisduval describes wh it is apparently
an interesting Western representative of the genus Cerura. A new
species of Ichthyura is described as Clostera incarcerata p. 80 ; but
from the text it is not certain that it is from (lilif »rnia. (Iluphisia
trilineata Park., is considered as the same as the European G. crenata
on p. 87, and additionally registered from California. As Alastor
gibhosa our Nadata gibbosa is registered from California. Dr. Pack-
ard has shown the existence of two closely allied species of the genus
from our Atlantic District. Should a species occur in California it

176 GROTE & ROBINSON.

could hardly be identical with either of them. This paper of Dr.
Boisduval's ends with a list of the Noctuidae of California collated from
M. Gueuee's works and descriptions of two new species of Brephos,
viz : B. californicus, Boisd., and B. melanis, Boml. p. 88.

From a perusal of this paper of Dr. Boisduval's it will be seen, that the
acquaintance of that distinguished Entomologist with his subject ha?
not greatly increased since 1852, the date of his first paper; while. a
knowledge of American entomological publications since that date
would have obviated alike the redescription of several species and the
appearance of refuting for the first time many errors of the older
writers already well understood and corrected in this country.

immaculate. Primaries beneath dusky. Head entirely i'ulvous yel-
low. Body parts above whitish, beneath with the legs dusky. Exp.

Ilahitat. — Texas (Belfrage). Form of L. casta Sanhorn, but a

ARCTIINAE.
We have received from Texas specimens of a moth with dun-colored
semitransparent wings, reminding us of Kuphanessa, but with plu-
mose antennae and other characters more nearly allying it to the
Arctian genus .Euchaetes, for which we propose the name:

Vanessodes clarus.

While the eyes are large and globose, the head itself is relatively
small. The ciypeus is narrow and its sides comparatively straight.
The frontal scales converge from the sides of the ciypeus, while those
from the occiputal region depend forwards between the antennae.
The labial palpi are divaricate, exceed the front and are coarsely
scaled so as to conceal the joints. In this respect the moth does not

AMERICAN LEPIDOPTERA. 177

differ greatly from Euchaetes. The head is relatively smaller than in
Euchaetes and held freer from the thorax. The scaled male antennix; arc
bipectinate, dependant at the tips and are shorter, the pectinations lon-
ger than in Enchaetes. The antennus thus reminds us of the succed-
ing Dasychirid Group. We have counted thirty three (33) pairs of
these pectinations. In the female the pectinations are reduced so that
the antennus appears simple; it is provided with setal hairs. The
smooth and closely scaled legs are rather long and slender, the tarsal
joints hidden by the close s(|uaujation. The hind femora are provided
with two pair of short spines ; one, the shortest, at the apex of the joint ;
the second, beyond or without the middle. The femoral spurs are
shorter than in Euchaetes. The female abdomen is short and plump,
reminding us of certain Lithosiid genera. In the male it is slender,
but hardly exceeds the aual angle of the secondaries in length.

The wings widen outwardly more than usual ; hence the outline is
not dissimilar to Ameria and other Lithosian genera. However the
neuration differs essentially. In Ameria and Euphanessa we have a
small triangular supplementary cell formed above the discal cell, and
a different plan of costal nervulation. From these, Vanessodes and
Euchaetes both differ. lu the present genus the subcostal uervure
emits two superior nervules which join the costa before th,e apex.
Beyond these, two inferior nervules are thrown off from the nervure
to the external margin below the apex. The extremity of the s. c.
nervure is shortly furcate at the apex of the wing. The course of the
median nervure and nervules differs from Euchaetes, in which the 1st
2d and 3d m. nervules arise together. Here the 1st, 2d and 3d are
thrown off at intervals, the discal cell is open. Here is no median fold
as in Ameria and Euphanessa. The open discal cell of the secondar-
ies is propiirtionaJly longer and narrower in Vanessodes than in the
two last mentioned genera ; so that the m. nervules are shorter and
the whole wing narrower. The four m. nervules are thrown off as on
the primary at unequal distances and again at variance with Euchaetes
in this respect. The submcdian fold is wanting or very slight in
Vanessodes, in which there are two inferior nervures.

Vanessodes clarus has the four wings immaculate and concolorous
above and below, while the nervules are a little darker. The tint is a
deer or mouse color. The head behind, a few scales at the base of the
fore wings and tlie abdomen above are soft yellowish. Beneath, thcr
abdomen, legs, palpi ami fnmt are a little darker tlian the wings, as is
the thoracic disc above. It expands from 22 to 24 uiillemetres. Al-

tion.

are darker above and the primaries below than in A. rubricoma. The
anterior wings are more elongate; the costal and internal margins are
more parallel so that the wing does not widen outwardly as in A. ru-
bricoma. The name is a MS. one of M. Gueuee.

Acronycta funeralis, G. <£• li.

This species is apparently the American representative of the
European A. alni. Tt differs in the extent of the black, shading of
the primaries and their shape and ground tint.

Acronycta afSicta, Grote.

This species has occurred in Penu.sylvania.

LEUCANIA, Ochs.
Leucania rubripennis, n. sp. ( Plate 2, fi;^. 77, J. )

% 9 • — Obscure straw color. Disc of the thorax and upper edge
of the prothoracic pieces darkest; collar in front very pale. Anterior
wings rather long, narrow, produced at apices. Primaries broadly
shaded longitudinally with purple rosy. First from the base out-
wardly and continuously below the median nervure to external margin.
Again from the discal cross vein outwardly, widening and running
obliquely upwardly to external margin. Finally along the outer half
of costal region. No discal dot. Secondaries thinly scaled, semi-trans-

parent, stained along the edges with obscure straw color and sometimes
with purplish. Beneath without marking ; the primaries outwardly
and superiorly stained with purplish. Exp. 32 to 34 mm.

Habitat. — Texas (Belfrage). With the appearance of the typical
species of the genus, L. rubripennis differs from all known to us by
the broad purple rosy shades of the primaries.

HELIOTHIS, Ochs.
Heliothis citrinellus, n. sp. ( Plate 2, fig. 79, %.)

% 9 . — Pale lemon yellow. Head, thorax and primaries concolorous,
pale lemon yellow, immaculate. Hind wings silky white. A blackish
discal lunule and terminal band broken and discontinued inferiorly.
Abdomen whitish, stained with dusky. Male with discolored genital
tuft. Beneath, both wings whitish. Primaries with distinct black or-
bicular and reniforra spots and subterminal band. Secondaries with
discal spot and faint indications of terminal band. Female genitals
concealed. Exp. 25 — 27 mm.

Hahitat. — Texas (Belfrage). Very different in coloration from any
species known to us. The following species of Heliothis, from North
America, are in our collection :

Heliothis exprimens,

Heliothis c.r2n-i7nens, Walk. C. B. M. Noct. p. 687.

Not uncommon from Canada to Pennsylvania. Resembles the
European Heliothis umbra (Ili/droccia umbra, Hcl. marf/inata Auct.),
and is not improbably identical with it.
Heliothis nmbrosus.

Heliothis nmbrosus, Grote, Proc. Ent. Soc. Pliil. Vol. 1, p. 219 (1863).
Habitat. — Massachusetts to Texas. A common species, destructive
to the Cotton Plant in its larval state. This is the Boll Worm of
Agricultural writers. Not improbably the same as the European H.
armigera.

Heliothis phlogophagus.

Heliothis phlo.cipliw/a, (err.) G. & R. Trans. Am. Ent. Soc. Aug. 18fi7.

ANTHOECIA, Boisd.
Anthoecia thoreaui, n. sp. ( Plato 2, fig. 80, 9 • )

S 9 . — Obscure olivaceous blackish ashen. Size large. Primaries
with the middle field palest; tliis latter margined on either side by
the two usual pale arcuated and flexuous lines which are narrower
and fainter than ordinarily and limit the dark basal and terminal
fields of the wings. A diffuse darker discal spot. Secondaries with
broad diffuse faintly darker borders and ftunt discal spot, somewhat
silky and tinged with browni.sh. Beneath, the secondaries are palest.
Both wings show indistinctly discal spots and double transverse suh
terminal lines. Exj). 36 to 38 mm.

ILthifaf. — Atlantic District. Resembles A. marginata (^4. rlvulomt-
Guen.) but is much larger more obscurely colored and wants the pro-
minent white median lines of that species. In A. thoreaui the median
lines are less even, more irregular than in A." marginata. We have
specimens before us from N. Y., Penn., and Alabama. A. marginata
occurs commonly from Mass. to Texas. A. thoreaui is of less fre(juent
occurrence than its ally, but will probably be taken in the same locali-
ties.

TARACHE, Hdbner.
Tarache cretata, n. sp. ( Plate 2, fig. 78, 9 • )

% 9 . — White. Primaries whitish with faint traces of a transverse
anterior "shade ; a triangular dark clouded spot at the middle of costa.
A dark purplish terminal space widening to internal margin, i nter-
sected by two narrow rivulous white lines, the outer the most distinct.
This dark terminal space is shaded with olivaceous along its inner
edge inferiorly, while at the apex there is a reddish lunulate mark
more or less distinct. Fringes whitish. Secondaries whitish, irides-
cent, more or less stained with blackish along external margin. I'n-
dersurface immaculate; primaries largely stained with blackish. Head
and thorax white, immaculate. Legs white, silky. Exj). 20 to 22
mm.

Habitat. — Texas (Belfrage). A smaller species than T. delecta,
wanting the yellow secondaries. With that species the terminal space
of the primaries shows a resemblance in color and ornamentation to

the genera Eudryas and Ciris. The present species recalls in this re-
spect quite strongly 0. wilsonii, although a much smaller insect.

PHALAENIDAE.

FIDONIA, Treiis.
Fidonia fimetaria, n. sp. ( Plate 2, figs. S4, 85, 'J, ; Rfi, 9 . 1

S 9 . — Dark brown and ochreous. Upper surface of wings dark
brown ; costa of primaries sprinkled with ochreous scales and an ante
apical ochreous transverse band broadly incepted on costal region.
Fringes pale interrupted with brown. Female paler than the male
and showing a terminal macular band at apices of primaries. Beneath
the secondaries are dark ochreous tratisversely banded with whitish
nacreous. At base there are irregular sp:)ts. Beyond, an interrupted
ante median band ; a second, post median, is continued and there is a
regular series of ovate neatly detiiied intersp:tcal spots. These bands
of nacreous scales are all relatively narrow and strongly limited by
dark scales. Primaries dark with a terminal series of spots inaugu-
rated at apices and the inception of the ante apical band marked ou
costal region. Body brown sprinkled with ochreous beneath. Abdo-
men above ochreous, with segmentary marks more apparent in the fe-
male. Exj}. 12 to 24 mm.

Habitat. — Texas (Belfrage).

Closely resembles the European F. fasciolaria, IIi(/n. sp. {Fid. cre-
braria, Auct.) and represents the genus typically in our fauna. Our
species seems a little smaller, the female darker. Ou the undersurface
of the secondaries the ground tint is brighter and the comparatively
narrow well defined pale bauds contrast strongly with the wide diffuse
and irregular white marking of T. fasciolaria. Our species has the
thoracic parts beneath ochreous not whitish. Finally the regular ser-
ies of terminal ovate interspacal spots on the hind wings beneath in F.
fimetaria, are replaced by a vague interrupted terminal band in F.
fasciolaria, in which latter species the ante median band is not de-
fined, while the % antennae in F. fimetaria are decidedly more .plum-
ose.

Eleven specimens have been sent us from Texas by M. Belfrage,
taken in the month of August.

AMERICAN LEPIDOPTERA. 183

List of the SPHINGIDAE, AEGERIIDAE, ZYGAENIDAE and BOMBYCIDAE

of Cuba.

BY AU(i. R. OROTE.

Since the publication, in 1867, of the Cuban moths belonging to
these Families, a few fresh species have been added to the number
and are included in the following List. Comparisons have also been
instituted between these insects and those belonging to the same
Families from Jamaica, contained in the British Museum and de-
scribed by Mr. Francis Walker. In this way a few specific synon-
yms have been detected and some generic changes found necessary'.

I still exclude, as belonging to the Noctuidac, a species of Nystalea,
Guenhe, and a Crino, Hiihner, bearing the Nos. 307 and 2ol of Prof.
Poey's Collection. This latter may be called Crino dissimilis ; I have
examined specimens in the Berlin 3Iuseum and have four before me.
It is of a pale ferruginous color, more reddish than C. besckei, Hiibner
which it otherwise closely resembles. The fore wings are without
prominent markings except an arcuate pale line arising from the base
at internal margin and extending upwardly to the disc. A similar
pale line is apparent along internal margin at base. Between these
lines lies the darkest portion of the wing. Transverse an^ulated
shades cro.ss the wing terminally. The secondaries are paler than in
C. besckei, while in size the species are similar. Although this may
ultimately be found specifically identical with its Brazilian ally, I re-
cord it under another name since I perceive points of difference and.
with a different habitat we may expect a representative species.

I exclude Sesia thysbe from the present List, as, from recent dis-
coveries in the United States, I am led to believe that if a species of
this genus really occurs in Cuba, it will be found to be distinct from
the common one of our Middle States. Possibly 8. floridensis may oc-
cur in Cuba; but more likely an autochthonus species will be dis-
covered.

Male. — Expands 1.7 inch. Upper side white with a sHp^ht yellow
tinge ; the base and costa of primaries and the base of secondaries, as
well as nearly one-third the wing along median ncrvure to abdominal
margin, densely sprinkled with black scales ; on arc of primaries, a
large, rhomboidal, black spot not reaching the costal edge ; hind mar-
gin bordered by a series of serrated black spots, obsolete next inner an-
gle, preceded by a curved black band of irregular width, and enclosing
a series of serrated white spots. Under side of primaries suffused
with yellowish green on outer limb ; marked as above, the discal spot
being replaced by greenish black, and the marginal spots by yellowish
green, except that part of the curved band which lies in the upper and
lower median interspaces, which is black.

Secondaries have the nervures throughout broadly bordered with
dark yellow-green, so as nearly to cover the entire surface, leaving
only narrow yellow stripes between the nervules, one in cell and an-
other reaching from ba.se to costal edge.

Body above covered with blue grey hairs ; beneath greenish yellow ;
palpi yellowish tipped with black ; antennae white annulated with
black; club black tipped with ferruginous.

From Nevada ; in the collection of Henry Edwards, Esq.

Allied to Sisj/tnbri, Bois., and Vernalls, Edwards, but readily dis-

ries and the extent and intensity of the green shade of secondaries.
ArGYNNIS BiSCHOFFlI, n. sp.
Primaries broad; costa slightly arched; hind margin unusually convex.

Male. — l^xpands 1.8 inch. Upper side dull fulvous, the base of
primaries and the base and abdominal half of secondaries brown ; pri-
maries have the submarginal lunules and marginal band closely con-
nected so as to form a broad black border, within which are eight ful-
vous spots from inner angle to apex ; other markings as in the allied
species, but delicate. Secondaries have a narrow black border on

which rest the lunules, but not forrains; one united band as on primaries ;
Ihe median band formed of separated spots from costa to disco-central
nervule, thence heavy, confluent, and lost on the brown marginal space;
on the arc a large open curved mark; fringes pale luteous.

Under side of primaries pale cinnamon brown at base, fading to pale
oehraceous on costa and apically ; the markings of the upper side re-
peated imperfectly ; hind margin brown, with pale lunules, not silvered,
above which are serrated black spots, only distinct toward inner angle.
Secondaries buff, inclining to oehraceous, mottled with greyish green ;
the spots paler, yellowish; the subuiarginal seven in number, broad,
serrated; the second row of seven, the first, second and third subovate,
of nearly equal size, the fourth minute, the fifth ovate, twice the size of
the first, the sixth ovate, smaller than fifth, seventh semi-oval ; the
third row of three, and two in cell; another at base of sub-cost;il and a
stripe at base of median.

Body blayk, with fulvous hairs; benaath grey falvou-i; pilpi fulvjus ;
autennse brown above, fulvous below ; club black, tip ferruginous.

Female. — Expands 1.9 inch. Deeper colored, with a pale or faded
space on inner mai'giu ; hind margin of primaries broader, rather
erose within, the enclosed spots whitish, as also are those of seconda-
ries. Under side as in male.

MELiTiEA Sterope, n. sp.

J/«/e.~Expauds 1.8 inch. Upper side blackish brown with white spots;
primaries have two rows of small spots parallel to the murgin; a third
row, sinuous, of large spots, bifid anteriorly; two spots in and one be-
low cell. Secondaries have a marginal row of large crescents or
rounded spots, preceded by a second of points, and by a third of
elongated spots crossing the disk; a white point in cell ; fringes fuscous.

On under side of primaries the white spots re-appear, but diffused ;
hind margin bordered by a narrow oehraceous band on which rests a
series of white crescents preceded by an oehraceous space; within this a
row of white points ; in cell a transverse white bar and a spot on cos-
tal nervure ; a large spot bahind cell ; remainder of cell and base
oehraceous. Secondaries have a marginal row of large white crescents,
edged above and below with black, preceded by a white band which is
limited anteriorly by a sinuous black line extending across the disk ;
