found within the lluited States.

BY W. H. EDWARDS.
Argynnis Artonis.

Male. — Expands from 1.5 to 1.8 inch. Upper side uniform yellow-fulvous, very
little obscured at base; all marks delicate, and as in Eurynome ; the mesial baud
on secondaries made up of separated crescents (in the examples under view.)
Under side of primaries paler; the marks in cell and those of mesial row re-
peated ; the P-shaped spot in cell fulvous within ; the extra discal row but im-
perfectly rejieated and all the marginal markings nearly obliterated. Secondaries
light yellow-buff, sometimes with little or no fulvous, but in other cases mottled
over disk with pale fulvous; the band between the outer rows of spots buff,
immaculate; the marginal spots faint, as on primaries; the spots of disk shaped
as in Eurynome, but pale-yellow, very slightly edged on basal side with black,
often but a few scales; most of those of second row have little dusky spaces at
their outer ends ; no trace of silver on either wing. Body fulvous above, yellow
below; legs reddish-yellow; palpi yellow, at tip red; antennre brown above,
ferruginous below ; club black, at tip ferruginous.

Female. — Expands 1.9 inch. A shade redder than male, the costa and apex (;f
])rimaries buff; the marginal lines heavier and more or less confluent on both
wings; all the markings heavier; the mesial band on secondaries confluent.
Under side of secondaries cinnamon-brown over basal area and disk, the apical
area and hind margin, as also costa next apex and the upper half of cell, yellow-
buff; spots as in the male, the marginal almost obsolete. Secondaries yellow-buff,
all spots obsolescent.

This form has been supposed to be a variety of Eurynome^ with which
species it flies in Colorado, but is rare. Mr. Mead met with three or four
examples in 1872, though he took great numbers of Eurynome. I have
received a single male from Big Horn, Montana ; and recently have seen
two females from Wells, Elko Co., Nevada; a region where, so far as I
know, Eurynome does not fly. These formed part of the collection of
Mr. J. Elwyn Bates of South Abinglon, Massachusetts ; and he informs
me that he received twenty-six examples, and that the typical Eurynome

was not taken in the region from which these came. Art on is may be
distinguished by the absence of silver and obHterated marginal spots
on both wings.

Argynnis Liiliana, II. Edw., Proc. Cat. Acad. Sci. Dec. 1876.

Mr. Edwards described this species with some hesitation, but it is un-
doubtedly a good species. During the last three years Mr. 0, T. Baron
has taken very many examples in northern California, and the char-
acteristics are uniform. I have living larvae at the present time, from
eggs obtained by him from a female in confinement.

Mr. Edwards says of this species : " It is intermediate between
A. Calippe Bdv., and A. Coronis Behr, partaking of the characters of
both. . . . Upper side of a rich reddish-brown. Beneath, the
primaries are largely suffused with reddish-brown, as in Corotris, but the
remainder of the wing is occupied by bright buff, not dull ochreous, as
in Corniiis. The silver spots of the margin are very decidedly triangular,
and not ovate as are the apical ones of Coroiiis. On the lower wings
the differences are more apparent. The silver spots are larger propor-
tionally than in any other species with whif;h I am acquainted, while the
sheen of the silver is exceedingly vivid and intense. The marginal spots
are quite triangular, and the large one of the cell more decidedly oblong
than in either Coronis or Cttlippe. The ground color of the wing is
bright buff, inclining to orange," etc.

To this I add, that the species is of medium size, the % expanding
about 2 inches, the ? about 2.2 inch. ; that the female is paler, some-
what mottled on upper side with yellow-fulvous on disk of primaries,
and the submarginal spots, within the black crescents, are yellowish on
both wings. So the spots on secondaries which represent the second row
of silver spots are paler than the ground.

Mr. Neumoegen has received from Mr. Baron a singular variety of
Lilianu % , which I call var. Baroni. The two marginal lines are very
heavy, and in place of the lunules is a third broad line crossing the whole
wing ; the series of rounded spots on each wing is represented by a demi-
line from costa, and by two round spots in the two median interspaces,
the rest of the row wanting ; and the mesial bands are changed from a
row of confluent crescent spots to a continuous zigzag narrow band ; the
spots in cells are unchanged. On under side about half of primaries is
yellow-buff; namely, all except the area next base below median and the
base in cell, besides two spots in cell ; secondaries same, yellow-buff ; the
margins ferruginous-brown and disk mottled with same ; on primaries
a continuous silver bar extends from costa to median instead of the

DIURNAL LEPIDOPTERA. 3

three usual silver lunulate spots, and on the subapical patch the silver
spot is twice as large as in typical examples. Secondaries have a con-
tinuous submarginal silver bar instead of lunules, and the three silver
spots of second row next costa are confluent, making one great spot.
The other spots are not changed.

Eurygona Abreas.

Male. — Expands 1 inch. Upper side dark brown, red-fulvous over disk of
])riinaries and to base, and over inner half of secondaries. Under side reddish-
drab ; a common red band (color red lead), crosses the middle of the wings, nearly
straight from costa of primaries to lower branch of median on secondaries, then
turning up to inner margin ; between this and hind margin a common pale brown
stripe, and the margins are narrowly edged with same color; but on secondaries
the posterior half and inner margin for a little distance are edged red; along this
on hind margin is a series of subcrescent white spots, the upper one in upper
median intersjjace being surmounted by a large rounded black spot; from the
second branch of median to outer angle is a series of yellowish spots limited by
the brown strijje.

From 1 S , fnjm Arizona, in collection of Mr. Neumoegen.

Liycsena Cyna.

Female. — Exj)ands .9 inch. Upper side purplish-blue; primaries have the apex
and hind margin ))roadly bordered with fuscous; at the end of cell a short fine
black streak; secondaries narrowly edged with fuscous except on costal margin.
Under side light brown-buff thinly washed white ; both wings have a marginal
series of buff spots preceded by a crenated line of same hue, all on white ground ;
primaries have a transverse row of brown .spots, eight in all, the first five, counting
ujj from inner margin, forming a convex row almost parallel with hind margin ;
the line then bends on apical area and the last two spots are on costal margin at
one-half and three-fifths the distance from apex to base; these two spots are
smaller than the rest and in line with them ; over the sixth spot of the row is
another one, minute; at the end of cell a buff bar, and another near middle.
Secondaries have a much curved discal row of smaU spots, seven in all, besides
three across basal area and one quite at base ; in cell a faint bar.

I received this example some years ago from the late Mr. Boll, who
took it at San Antonio, Texas ; and I kept it hoping that in another
trip which he planned, he might find the male. The species stands
near Gijdi^.

Pamphila Harpalus.

Jl/a/e.— Expands .95 inch. Upper side red-fulvous over disk and costal margin
of primaries ; pale brown at base ; hind margin edged broadly with same ; stigma
long, slender, widening a little toward base and bent down, black ; in subcostal
interspaces three minute fulvous spots and two others in the border opposite cell.
Secondaries brown, the disk fulvous, obscured except in discoidal interspace which
is clear fulvous nearly to hind margin. Under side of primaries pale fulvous,
yellowish next inner margin, ochreous over apical area ; at base black. Secondaries
ochre-yellow; on disk a narrow band bent near outer angle and extending a little
way toward base; in cell a patch; this and the band are paler than the ground
but are not very distinct.

4 WM. H. EDWARDS.

Female. — Same size. Colors paler, the brown restricted ; the lower median and
submedian interspaces a little obscured, and two brown streaks in discoidal and
upper median intersjjaces ; the brown border sends out long serrations, and a faint
j)ale band crosses the wing next inside the border; secondaries have the disk clear
fulvous, all the margins brown, the hind margin serrated as on primaries. Under
side of both wings uniform yellow-buff; the irregular band of primaries is better
defined than on upper side, paler than the ground; so on secondaries the band is
whitish, of same shape as in male but rather more distinct.

From 1 % , 1 9 , received in 1878, from Mr. Morrison, taken in
Nevada. The species is nearest Sassacus.

PanipSiila B>eva, Elw., Trans. Am. Ent. Soc. v, 289.

I described a female of this species received from Prescott, Arizona ;
Mr. Neumoegen brought from South Colorado a second female which
differs somewhat from the type. The translucent spots on primaries are
larger, and on the under side of secondaries are indistinct traces of two
macular bands, one abbreviated on middle of disk, the other nearly half
way between the first and hind margin, almost perpendicular to inner
margin and bending to costa at a right angle; these bands are brown,
while over the wing is a gray bloom. The same bloom covers apex of
primaries. In the type, which is more worn than the Colorado example,
this gray surface is absent and the brown spots do not appear. But
I think there can be no doubt that both females belong to one species.
The S is yet unknown.

Pampliila €abeln!«.

Male. — Exjjands 1.2 to 1.3 inch. Upper side yellow-fulvous; the hind margins
of jirimaries broadly edged with pale fuscous, of secjondaries very narrowly ; the
sexual mark long, slender and curved; on costa near apex are two or three
obsolescent little spots, and two minute ones opposite cell in marginal border.
Under side reddish-fulvous over both wings, except the apical area of primaries
which is yellowish, and inner margin pale yellow; a little black at base and a
dusky patch at inner angle ; secondaries golden-yellow-fulvous, with a few small
spots of paler color; one in cell near outer end, one in lower subcostal interspace,
and two minute spots in the median interspaces, these three making a line across
the disk ; also a minute spot in discoidal intersj)aoe near margin. One example
has no trace of these spots on secondaries.

From 8 % 's taken in Nevada by Mr. Morrison in 1878. The species
is allied to P. Oltoe Edw.

Pamphila Yerus.

ilfa/e.— Expands 1 inch. Upper side yellow-fulvous, the margins pale fuscous,
broad on primaries, narrow on secondaries; on primaries three indistinct subapical
dots on costa, and a series of small spots oblique, crossing median intersi^aces ;
sexual mark black, slender, broken pn lower branch of median but not separated,
edged by black somewhat on either side ; at its upper end a fuscous patch connects
it with the marginal border. Under side of both wings bright yellow-fulvous;

DIURNAL LEPIDOPTERA. 5

secondaries immaculate; primaries have a little black at base and a streak repre-
senting the stigma ; the indistinct spots of upper side repeated, but still more
obscure, scarcely to be seen except in certain lights.

Female. — Same size; generally like the male but paler; the spots more definite
and semi-translucent ; a fuscous patch in place of the stigma. Under side paler
than male.

From 1 S , 1 9 , taken at Havilah, California ; and in the collection
of Mr. Henry EJwards. The species is allied to Agricola Bois.

Panipliila Regulus.

Male. — Expands 1 inch. Upper side black-brown; primaries have a straight
black sexual mark ; also three white dots in the subcostal interspaces, two more
at end of cell one over the other, two near hind margin opposite cell ; and two
streaks or spots in line with the lest mentioned spots and making with them an
oblique line which if protracted would reach middle of inner margin. Secondaries
immaculate. Under side paler, the sjjots on primaries repeated and enlarged; on
secondaries a straight line of four small spots across middle of wing, two at right
angles with the outer end of this line and extending up costal maagin ; one ou
costal margin nearer base, and one in middle of wing; in all eight spots. Body
above and below concolored with the wings; palpi buff.

Female. — Expands 1.3 inch. Same color and marked in same way, but the
spots larger.

From 2 S 's, 1 9 i sent me for inspection by Mr. J. Elwyn Bates of
South Abington, Massachusetts ; and received by him from upper St.
John's River, Orange Co., Florida. Near Atxius, but very much spotted
with white.

Pampliila Lag 11s.

Male. — Expands 1 inch. Upper side yellow-fulvous; primaries have a very
narrow fuscous border to hind margin, and this is extended round apex and along
eosta for a little distance. Secondaries have a still narrower border, but both
costal and inner margins are broadly fuscous; at the end of cell of primaries the
arc is black and subcostal next the arc is bordered black ; fringes long, pale fulvous.
Under side of both wings light 3'ellow, with a slight fulvous shade over middle
of primaries; base of same wings and part of inner margin black; secondaries
immaculate.

I formerly recaived a single male of this little species ft-om Mr. Boll,
taken in western Texas; and recently Mr. Nenmoegen has brought
another male from Southern Colorado, taken at Oak Creek Canon. The
female is still unknown. The species is allied to Delaicare.

Painpliila Taxiles.

Male. — Expands 1.1 inch. Upper side glossy yellow-fulvous, the hind margins
bordered narrowly by fuscous; in some examples the dark portions are greatly
restricted, forming but a slight edging; costa of secondaries fuscous; primaries
have a fine black stfeak on arc, sometimes Avanting; fringes of secondaries and
along inner angle of primaries fulvous, the remainder fuscous. Under side of
primaries paler: basal area black, with a spur along inner margin; hind margin
Lndistinctly fuscous; in the subcostal interspaces three yellow spots. Secondaries

(T WM. H. EDWARDS.

mottled briglit yellow and pale red-brown, the yellow prevailing on disk, the
other bordering hind margin and forming a band across basal area, besides a demi-
band on middle of wing from inner margin.

J'eOTa/c.— Expands 1.2 inch. Upper side fuscous mottled with pale yellow
fulvous; the hind margins broadly fuscous; the basal areas pale fuscous; the-
fulvous occupying the disks, not clearly defined, and especially on primaries much
obscured ; primaries have three translucent spots in the subcostal interspaces ; two
fulvous spots anterior to these last and opposite cell ; and two translucent spots of
larger size in the two median interspaces; in some examples these median spots
are yellow, not translucent. Under side of primaries blackish-brown at base,
brown over apical area and hind margin; the costal spots and those against cell
repeated, the median spots indistinct. Secondaries red-brown, indistinctly mottled
with fulvous across middle of disk and along costal* margin and at base; inner
angle brown-fulvous. In some examples this wing is scarcely mottled, but nearly
uniform red-brown, and is flushed with grayish-purjile ; so also is the apex of
primaries.

Taxites is near Zabulon, a species which varies greatly. The most
evident distinction consists in the extent of the fulvous area in the male,
and in the translucent and other spots on fore wings of the female.
I have examples of Za/mlon, taken at Coalburgh, which have the
under side of secondaries mottled in same way as in this western form,
and examples of the female, especially in the melanic dimorphic form
Pocahontas Scud., are very close in the resemblance of under side to
the usual t}^>e of Taxilcs. This replaces Znbulon on the Pacific slope.
1 have examples from Arizona, also from South Colorado and Nevada,
taken by Mr. Morrison ; and Mr. Neumoegen found several at Oak
Creek Canon, South Colorado. Mr. H. Edwards has a female taken
in California.

Amblyscirtes Siinius.

ilf«/e.— Expands .85 inch.— Upper side grayish-brown with a silky gloss; pri-
maries have a white spot, fulvous tinted, at end of cell, and a bent row of similarly
colored small spots across disk from costa nearly to inner margin ; of these three
are perpendicular to costa and the others form a line oblique to them, a little
sinuous, curving in submedian interspace towards inner margin; secondaries have
on disk traces more or less decided of a narrow fulvous band above median j
fringes Long, cinereous. Under side of primaries fulvous in cell, and fulvous
washefl gray over disk and to inner margin; apical area gray; the basal area
below cell pale fuscous; the spots repeated and a little enlarged. Secondaries
light gray-brown; on the disk a whitish band nearly parallel with costal and
hind margins; and an indistinct whitish patch near base below cell. Body dark
fuscous above, yellow-gray beneath; palpi white at base, gray above: antennae
white beneath, annulates white and black above, club ferruginous.

-Fewio/e.— Expands .95 inch. Upper side lighter, rather yellow-fulvous obscured
by brown ; the basal areas and hind margin of primaries being darkest ; spots as
in the male, not distinct. Under side as in the male, but paler.

From 1 ^ , 1 $ , taktn at Oak Creek Canon, Colorado, by Mr.

DIURNAL LEPIDOPTERA. 7

Neumoegen ; and 1 % sent me by Mr. Lintner, marked '' Pueblo,
Colorado."

Pholisora Pirus, Edw., %; Field and Forest ,3, 144. 1878.

Female. — Expands .9 inch. Lighter brown on both sides than the male and
marked in same manner.

The male was described nearly as follows :

Expands .9 to 1 inch. Upper side glossy dark brown ; primaries have three
small yellow spots near apex, a point in each of the two median interspaces ; also
one within and near end of cell just below subcostal; secondaries immaculate;
fringes light brown. Under side of both wings castaneous, the disk of primaries
blackened ; the spots repeated, a little enlarged, yellow. Body fuscous ; below the
thorax gray-brown, abdomen same, reddish at sides and extremity; legs reddish;
palpi white at base, yellow above with many black hairs; antennae black with
five rings of yellow, on under side yellow ; club black, tip ferruginous.

Hah. — Southern Colorado.

Neonympha Henshawi = Euptychia Hennhawl, Edw., Tr. Am. Ent. Soc.
5, 205.
This species Wtis originally taken in Arizona and New Mexico. Mr.
Neumoegen took several examples at Oak Creek Canon, Colorado. The
species resembles N. Gemma Hubner; is twice as hu'ge and russet^
beneath. The female also is russet above.

I<einoilias Nais = Ghrr/aophanus Nais, Edw., Tr. Am. Ent. Soc. 5, 291,

Described from a single % taken formerly by Dr. Smart in South
California, and a 9 received from Prescott, Arizona. Since taken at
Denver, Colorado, (IS) and found to be common in Southern Colorado,
at Oak Creek Canon, by Mr. Neumoegen. The species belongs to the
sub-family Erycinidne, not to the Lycajnidae. Its habits are veiy differ-
ent from Chrysophanus, according to Mr. Neumoegen alighting on the
sand, etc.

Mr. Neumoegen writes thus : " Ntt in appeared at first about the
middle of July, in Oak Creek Canon, but was most abundant toward
the end of the month and beginning of August, entirely disappearing
by the middle of August. It was always found on open clearings
(which in a Canon means the highway, as there is^ no other clearing),
flying from 10 A. M. to 2 p. m., and invariably settling near moist
places. Its flight is of a rapid, zigzag character, much resembling
Melitfea."

I sent a pair of iVnis to Mr. A. Gr. Butler, to ask in what genua
of Erycinidaj it should stand, and received the following reply : " Zool.
Dept. Brit. Mus., 22 Nov., 1880. I do not wonder at your describing
the little butterfly as a Chrysophanus. It was a most natural mistake,
considering that the coloring and pattern are quite Uke that genus^

8 WM. H. EDWARDS.

and quite unlike the members of the genus to which it appears to
belong. In structure it agrees best with Apodemia, (I might say, it
agrees altogether), but the pattern of the under surface is not like
any member of that genus known to me, being more like the arrange-
ment found in Echenais. If color can be called a structural character
therefore, the species belongs to no known genus; but as I do not
consider this to be the case, I should certainly refer it to Apodemia,
In some respects Nais reminds me of Nemeobius, but the much less
developed club to the antennte at once precludes the possibility of
referring it to that genus."

To Apodemia Kirby refers 3Jormo, Virgulti and allies, which in my
Catalogue stand under Lemonias. I therefore place Nais with them,
in Lemonias, Westwood, which covers Apodemia.

Melita'a Arachne, Edw., $, Trans. Am. Ent. Soc. ii, p. 372, 1869.

I described Arachne from a single example taken in Colorado, and
expressed a doubt whether it might not be same as Minitta, Edw.,
Proc. Acad. Nat. Sci. Phila. 18B1, 161.

Of late years many examples of both forms have been taken in
Colorado, Arizona and West Texas. Mr. Neumoegen found Arachne
common at Oak Creek Canon, South Colorado ; and I have seen it in
his collection. The two forms are equal in expanse of wing in the
sexes, the 2 % 's measuring from 1.2 to 1.4 inch, the 2 $ 's about 1.4
inch. Both sexes are alike in markings and color. The only permanent
diiference which I have been able to discover is in the markings about
the hind margins of secondaries on under side. In Minuta this margin
is white, without black on the edge ; a little within is a fine black line
and en this line rests a series of large white spots, the anterior sides
rounded. The posterior side of each spot rests on the black line and
therefore is no mere curved than the line itself.

In Arachne the hind margin is edged wi'h a fine black line; and
instead of a submarginal fine line, the spots are placal on black ground
and the posterior side of each is largely incurved, sometimes much
angulated and this makes a black space quite unUke the mere line of
Mhinta. I have before me 6 Minuta % 9 , and 6 Arachne % 9 , and
ihcse difi"erences are constant. All the examples which Mr. Neumoesen
.--liowcd me Avere of the Arachne type. 80 were four (2 ^ . 2 9 ), for-
merly sent me by Mr. Boll from "West Texas, and 1 % which I have
from Arizona. This is enough to distinguish one form from the other.
and I shall Catalog-ue them as two species. 4'>'achne seems to inhabit
a more southern region than Minnta.

ttlURNAL LEPIDOPTERA.

Motes on the species of CAIiLIDRYAS found wifhin the
United States.

BY W. H. EDWARDS.

Until Mr. A. Gr. Butler, in his "Lepidoptera Exotica," London, 1874,
« monographed this group, figuring nearly or quite all the known species,
and that in both sexes, the confusion was extreme, and no apology was
necessary on the part of other recent authors for any errors they might
have fallen into. Now there is no excuse for error. Mr. Butler had all
the resources of the British Museum collection and library at command,
not to speak of the many other British collections, and his authority is
sufficient to settle any doubtful questions in this direction.

Following the best light I could find, I had given in my Synopsis
(Vol. i, Butterflies of North America, 1868-1872), four species as
belonging to our fauna.

1. Argante, Fabr., Syst. Ent. p. 470.

% Hersilia, Cramer, pi. 173.
$ Cipris^ Cramer, pi. 69.
9 Cindia, Grodart, Enc. Meth. ix, p. 93.

Hab. — Southern States, etc.

4. Marcellina, Cramer, pi. 163.

% Eubule, Bois. and Lee. pi. 24.

Mr. Scudder in a paper entitled " Remarks on the old genus Callidryas,"
Vol. xvii, Proc. Bost. Soc. Nat. Hist. 1874-5, followed Mr. Butler, and
gave the North American species thus :

1. Agarithe,

2. Eubule,

3. Sennae,

4. CiPRis, on authority of W. H. Edwards' Synopsis, etc.

TRANS. AMER. ENT. SOC. IX. (2) FEBRUARY, 1881.

10 WM. H. EDWARDS.

In my Catalogue 1877, following Mr. Butler, I gave

1. EUBULE,

2. Sennae,

3. Agarithe,

4. Philea,

striking out Gipria as more than doubtful.

Mr. Strecker, Syn. Cat. etc., 1878, with no reference to Butler's, gives :

1. Argante, Fabr., Syst. Ent. p. 470,

S ITersilia, Cramer, 2, pi. 173.

2. EuBULE, Linn., Syn. MarceUina.

? Var. Sennoe.

3. CiPRis, Fabr., Ent. Syst. 3, p. 212.

Neoci/pris, Hubner, Saml.

Bracteolata, Butler, Scudder, Proc. Zool. Soc. 458.

Finally in the Synoptic Table of Lepidoptera, printed in Bulletin of the
Brooklyn Entomological Society, Vol. i. No. 9, January; 1879, we have :

1. EuBULE, Linn.

9 var. Sennae, Linn.

2. Argante, Fabr.

3. Philea, Linn., evidently without knowledge of Butler or Scudder.

Recent authors therefore differing so much, I think it well to present
again Mr. Butler's view of these species, as his volume is not accessible
to many Lepidopterists.

1. Argante, Fabr., Syst. Ent. p. 470, is not a North American
species, but the species found within the United States and taken for
Argante is Agarithe, Boisduval. The most northern locality given by
Butler for Anjante is Oaxaca ; then Honduras, and Central and South
America. Argante is characterized by a " zigzag discal series" on under
side, etc., and Butler refers to Swainson's Illustrations for a Plate on
which he says both sexes are correctly figured. This is in First Series,
Swain. Illus. Vol. i, pi. 52. The "zigzag band" is shown to be com-
posed of two oblique red-brown stripes nearly parallel to each other, one
under the other, but unconnected. Mr. Butler's figures show the same
peculiarity. I know of no North American orange species which has
this sort of stripe.

DIURNAL LEPIDOPTERA. 11

Female. — Above generally golden-orange, sometimes pinky- white ; front wings
with diflfused orange patch over end of cell; a brown spot at end of cell; apex
an oblique series of spots between the nervures on disk, and a marginal series
terminating nervures black-brown; hind wings with costal and internal ones
rosy- whitish ; three or four blackish spots terminating the nervures on outer
margin ; wings below golden-yellow, irrorated with ferruginous atoms ; front wings
with base and apex red; a bluish subapical nebula; a geminate pearly brown-
zoned spot at end of cell; an oblique discal brown band and three spots between
subcostal branches ; hind wings with a red spot at base ; a transverse streak cross-
ing cell from costal nervure, a subcostal spot near base, and a semi-circular series
of markings, brown; two silver-centred ring-spots at end of cell.

Localities : — " Brazil ; Yucatan ; Texas ; (white var.). % var. spotless
below, Santa Martha."

I have had several males and females from South Florida during the
past season. The oblique red-brown band is distinct on under side of
fore wings of the male. The color of under side is bright yellow. One
female remains in my collection of these Florida examples. The upper
side is paler orange, the ground at end of cell deep orange. The oblique
band is obsolescent on upper side but distinct below. And the other
marks agree with Mr. Butler's description.

I have a 9 from Kansas, of which the upper side is ochre-yellow
rather than orange, and the oblique band is broad and complete on Ijoth
sides. Another from Texas is yellow-white on upper side, or sordid-
white, the band heavy on both sides. Another ? , Texas, is still whiter,
same bands on both sides.

3. Sennae. Butler gives the synonymy thus :

" Male. — Generally smaller than Eubule ; the coloring of the under surface deeper,
and the markings much better defined.

Female. — Above deep golden-yellow, sometimes inclining to orange, or dirty
white; front wings with internally dentated, well defined dark-brown margin
begini:iing at second-third of costa and terminating at anal angle ; a large black
disco-cellular spot, and a subapical series of anguhited lunules between the nerv-
ures; also a point of the same color between naedian branches; hind wings with
rosy margin; a submarginal series of fine large geminate dark brown spots at
termination of nervures; abdominal and basal areas pale rosy; under surface of
wings paler; the margin with band and spots as above, but deep rosy; front wings
with large geminate silver-centred ring-spot at end of cell, and a zigzag series of
irregular characters on disk, all rosy-brown; costa rosy, hind wings with two

silver-centred ring-spots placed obliquely at end of cell on a brownish streak, and
encircled by a series of bracket-shaped characters beginning at base and continuing
in the form of a heart through disk, all rosy brown.

Localities : — " Brazil ; Central America ; Mexico ; Texas ; Jamaica ;
Hayti," etc.

" The Phcehis Eubule of Hiibner, Samml. ex. Schmett. ii, pi. 31, 1805,
represents the two common forms of C. Sennae ; we have both examples
from Honduras." Butler, pages 59, 60, plate 23, figs. 1-4.

Until recently I have been unacquainted with the % of this species,
though I have seen many 9 s, and have for years had several in my
collection, from Texas and elsewhere. But in collection of Mr. Henry
Edwards, at New York, I saw two males alike, one of which he had
taken at Mazatlan, in copulation with a 5 ^^^^ J^J Texas examples.
The other % Mr. Edwards gave me. It is so much like Euhule, common
form, that it would be overlooked and no doubt has constantly been, as
the female is reported from many localities in the United States, This %
is less green, more yellow than Euhule % . The upper side is immaculate,
the marginal areas being nearly just as in Euhule. But the under side
has a reddish hue upon the yellow ; the zigzag streaks on fore wings and
other markings described by Mr. Butler are distinct. So all those on
hind wings, " the series of bracket-shaped characters beginning at base and
continuing in the form of a heart through disk " being clearly defined.

A 9 sent me by Mr. Scudder, labelled " C. Orhis, Poey, Florida Keys,"
measures 2.6 inches. Color white with a yellow tint, but not sordid.
Hind margin of primaries edged by a narrow brown band made up of a
confluent series of long spots crenate on inner side ; costal margin same
dark brown two-thirds towards base ; a large brown discal spot with an
orange streak on arc ; on the subcostal interspaces are three little brown
spots or clusters of scales in line near costa, and this row bends round
apex ; secondaries edged with double-convex brown spots which fill the
interspaces. Under side has the margins rosy -brown, the " zigzag bands"
distinct and the "bracket-shaped" spots, etc.

Another 9 from Texas, is same size as last named, but sordid white.
Marks same.

I have also a small 9 from Indian Eiver, measuring but 2.1 inch.
Color of the % described from Mayatlan. Below same red tint as that.^
and marked just like it. I had taken this for a dwarfed Euhulr, but
clearly it is JSennae.

4. Eubule. Mr. Butler gives the species thus :

"Male. — Wings above sulphur-yellow, unspotted, with narrow marginal mealy
band; below sulphur-yellow ; front wings with paler internal area; an irregular
rosy-centred ring-spot at end of cell, and a deeply bisinuate series of eight brown
spots beyond it; hind wings with two silver-centred spots at end of cell, encircled
by an irregular discal series of tea or eleven red-brown scale-spots, sometim^es
obsolete.

Female. — Wings above sulphur-yellow, with orange margin, the nervures termi-
nating in black spots; front wings with large black disco-cellular spots, and some-
times with an indistinct series of discal spots towards apex ; below golden-yellow,
the margins deeper colored; front wings with a large geminate silver-centred
ring-spot; the discal spots as in % but redder; hind wings with two silver-centred
ring-spots placed obliquely upon a squamose rusty band at end of cell, and en-
circled by a discal series of irregular reddish markings, several reddish spots
at base."

This species is common over the South and West, and is sometimes
taken on Long Island, or further up the coast. It is occasional at
Coalburgh, West Virginia ; and in season of 1880 there were an unusual
number seen there.

5. Hersilia. This species Mr. Strecker gives as synonymous with
Argante, Fab. ; Mr. Butler as follows :

In American Entomologist, 2, p. 340, 1870, we read : " A rare capture
in Illinois; H. S. Bontell, Evanstown, Illinois. The large sulptur or
citron-yellow butterfly with a large quadrate orange patch near the middle
of the front wings, and with the posterior part of the hind wings also
more or less orange is Callidryas Philea, Linn., the largest species of
the genus. Its habitat is usually given as Brazil, St. Domingo and Cuba,
and the fact of your capturing it in northern Illinois is interesting, and,
its occurrence there very exceptional," etc.

In my Catalogue I give Texas as occasional habitat, but on whose
authority I do not remember. I was very careful at time of printing
the Catalogue to admit no occasional species whose locality I had not
investigated, and therefore I am satisfied that the species has been taken
in Texas. As to Illinois the above extract speaks for itself.

These then are all the species of Callidryas thus far known to have
been taken to the North of Mexico, Eubule, Semiae^ Agarithe and Philea.
As to Cipris, attributed in my "Synopsis" to New Mexico, that was a
mistake on my part based on erroneous information, and I dismissed the
species from the Catalogue, 1877.

Synopsis of the IiAI»IFYRID.f<: of the United States.

BY JOHN L. LECONTE, M. D.

The term Lampyridae in this memoir is used in the same extended
sense as in my work on Classification of Coleoptera of North America.
The species may be naturally divided into three sub-families of equal
value, as follows :

Middle coxse contiguous; epipleurse distinct 2.

Middle coxa; distant; epipleurse wanting I. Ltcid^.

2. — Episterna of metathorax sinuate on inner side; epipleurse usually wide at

the base II. LampyridvE.

Episterna of metathorax not sinuate on inner side; epipleurse narrow at

base III. Telephorid^.

The relations of these and their respective tribes have already been
sufficiently indicated by me in other places* in a condensed manner,
and additional remarks will be found below under the appropriate
headings.

Since publishing the popular essay on Lightning bugs above cited, my
attention has been called by a friend, more familiar than myself with the
literatiu-e of physical research to an interesting essay by Dr. T. L. Phipson,"}"
in which some partially successful attempts were made to isolate the light
giving substance, to which the name Noctilucine was applied. Other
memoirs on this substance are cited by Dr. Phipson, but notice of tliem
would unduly extend the present remarks. |

If Dr. Phipson is. correct in stating that the cavLse of luminosity both
in living animals of such varied grades as the lower marine forms of Ufe,
the mp-iapoda and the complex terrestrial insects, and in the decomposing
masses of animal and vegetable material such as foxfire and putrid fish is
identical, these phenomena become even more worthy of careful study than
I supposed when I wrote my popular essay on Lightning bugs. For a
substance which is developed not only by normal physiological processes,
in the bodies of animals of very varied sti-ucture, but by the somewhat
fortuitous processes of ordinary putrifaction should certainly be within
easy reach of synthesis.

Dr. Phipson also states that the spectroscopic examination of the light
from these varied sources is contained within the space extending from
C to a little beyond F, " but its brightest portion lies between E and F,
and in most cases this portion only is visible, and the light appears nearly
monochromatic. It has no lines nor bands of absorption."

There are several remarkable phenomena exhibited in various parts of
the family which will receive more attention when the materials have
been collected, and the student found to prepare a general monograph.
They may be briefly stated as follows, for the purpose of guiding
observations :

1. The pupae of the Lycidae are frequently found in large numbers-
under loose pieces of bark, suspended closely together by the posterior
extremity, each one enveloped in its own larva skin, which is cleft on the
pleural lines as usual. Nothing of this kind has been observed in the
other two sub-families.

2. The elytra of certain Lycidas, though useless in flight, are expanded
to a degree unknown in any other Coleopterous family.

3. The sexual differences in the light organs of various genera of
Lampyridae have not been properly recorded. They furnish as will be
seen in the sequel, good generic and even specific characters.

4. The enormous vegetative development of the antennal branches
in Phengodes, and the entire want of knowledge of the females of
any member of the tribe.

5. The investigation of the relation between the Phengodini of this
continent and the Drilini of other regions, with a view to the possible
union of the two tribes.

6. While in the Phengodini we have an enormous development of
antennal surface, we have in Malthodes, probably the lowest form in
the family, an equally remarkable growth of the sexual appendages
of the male.

Telephoridse have occurred in tertiary strata ;* the geological history
of the other two sub-families is unknown.

Sub-family I.— LYCID^.

The species of this sub-family are diurnal in habits and are found on
the leaves of plants, where they seek their insect food.

They are known by the middle coxae being rather widely separated
by the niesosternum, and by the epipleurae being reduced to a narrow
thickened marginal line. Besides these essential characters of defini-

* Heer, Insecteu fauna . . . (Euingen <fe Eadoboj, 143.

AMERICAN COLEOPTEEA. 17

tion, other characters are seen in these insects not found in the other
sub-families.

The elytra are frequently costate and coarsely reticulate with fine
elevated lines forming a coarse net work, or more usually a regularly
goffered surface. The head is sometimes prolonged in front of the eyes
into a long narrow beak, which in other species becomes broad and short
and in many of the species entirely disappears. The mandibles are feeble,
slender and acute, the palpi are unequal and the eyes larger in the %
than 9 , though never very large ; they are widely separated above and
beneath. The antennj^ are eleven-jointed, but the second joint is some-
times very short and inconspicuous ; they are frequently very broad and
compressed, and the joints 3 — 10 occasionally emit broad branches, more
slender and longer in the % than in the $ ; frequently too, they are
only slightly compressed and subserrate, in this case the second joint is
very distinct and one-half as long as the third. The sexual characters
are simple ; the ventral segments are seven in the $ , the seventh being
lai-ge and slightly nicked at the tip ; they are eight in the % , the seventh
being broadly and strongly emarginate, and the eighth elongate-oval,
moderate in size and prominent. There are slight differences in the form
of the two last segments of % in our species, but as they are readily
recognized by other characters I have not deemed it prudent to encumber
the tables with minutiae of such small import which would probably
tend to confuse the student.

The genera represented in our fauna may be divided into three
natural groups : the first is typical and peculiar, the second tends to the
Lampyridae (gen.), and the tJiird to the Telephoridae.

This species by the form of the palpi, antennae, and number of elytral

Arizona, one 9 , for which I am also indebted to Prof. C. • V. Riley.
The form of the last joint of the palpi seems to require the reference of
this species to Calopteron, though the reticulation of the elytra and the
form of antenna? are quite different. It seems to belong to the Section A,
ii, of Biologia Centro-Americana, (Lycidas, p 13), in which case the %
antennae would be pectinate.

one, with which by modifications in different directions the other I'oriijs can be
readily harmonized: thus by completing the side walls of the anterior median
cell you have sculptilis, by obliterating the walls of the anterior median cell and
retaining the carina you have irilineatus ; by making the middle j)OSterior cell
vanish, but retaining a carina to re])resent its walls, you have crenatus ; finally
by obliterating the cell walls of the disc, retaining only the basal part of the
middle posterior cell, with the imperfect transverse elevated line connected with
it, you pass over to the genus Plateros. We have here evidently at comjilex in
which not only supposed generic characters are untenable, but the species are also
somewhat plastic and difficult to define.

The species of this sub-family are easily separated from the Lycida;
by the middle coxa; being contiguous, and the epipleurie wide at the base
of the elytra, even when the latter as in some 9 9 are very short.

From the Telephoridae they are known by the metathoracic episterna
being sinuate on the inner margin, a character first observed by Duval,
and which seems to me to have much value in apportioning the more
difficult forms to their respective groups.

The genera examined seem to indicate two tribes ; the first is numerous
on both continents, especially in the tropical regions ; the second is perhaps
exclusively American, unless it can be united with Drilini.

Tribe 1. — Lampyrini.

The most cliaracteristic structure in these insects is tlie light-givuig
apparatus which is contained in the posterior abdominal segments of most
of the species, though it is quite absent in some genera.

The position and form of tlie organs diflfer according to genus and in
a less degree according to species.

Tn most of the genera the sexes are similar in appearance, but in the
Lampyres -roup the $ are larger than S and larviform, with short elytra
and n.". wings. In these genera the eyes of the % have their maximum,
and those of the 9 the minimum development. In the other groups
the eyes of the % though larger than those of ? , are not remarkable
or disproportionate in size. The head is deeply immersed in the pro-
thorax which is foliate at the sides and apex, so as to protect the head.

The antennas are approximate or moderately separated, and vary m
form according to group and genus. Our genera seem t.^ indicate' the

In this iiTou}) the antenn;^ are more or less compressed, sometimes

verse {Lucidota). The sexes are similar in appearauce except in one
species of PhutinuH, where the elytra of the 9 ''i"^' short aud the wings
wanting. The eyes are larger in % than 5 ■ but are separated by a wide
space both above and beneath in all the species. In the % the last
ventral segment is small and narrow, covered l)y the scutate last dorsal,
which varies in form according to genus and species. The light organs,
when present, are more developed in % than $ . which is the reverse of
what obtains in the group Lampyres. Tlie head is always covered by the
hood-like prothorax. The epipleiu'te of the elytra are wide at the base;
the inferior (or distal) margin is reflexed. and converges more or less to
the lateral margin of the elytra. The elytra vary in color; in the
species without well-develo})ed light organs they are black, with the
single excejjtion of F/jropi/r/d: uidicta. where they are broAvn margined
Avith testacetms. as in the brilliantly luminous species.

It wdl therefore be especially necessary for the inexperienced stiulent
to ascertain in this group, to what genus his specimen should be referred,
before he attempts its specific determination.

There are in many families of Coleoptera strong resemblances between
species of diiferent genera, but I know of none (with the exception (jf
certain Rhynchophora), so deceptive as those which our own Hmited

by the insertion of a large band of fibres which ran transversely outwards. The
function of these muscles and their relation to the light organs are not yet under-
stood, but next summer when living specimens can be obtained, renewed observa-
tions will be made. Dr. Hagen thinks that these impressions can be traced, though
less distinctly, in other genera of this family and also in Elateridse. I have not yet
been able to satisfy myself that such is the case, though doubtless the same muscles

PHOTINUS Lap. emend. Lee. (nee Lacordaire).

This genus as emended by me (Pr. Ac. Nat. Sc. Phila. 1852, 33-1),
differs from the preceding by the prothorax not at all carinate, but
usually slightly channeled, and more obtusely rounded in front. The
surface is pale, tinged with rosy, and is usually marked with a dusky
spot or stripe. The light organs are always larger in the % than in
the 9 , and in the latter sex vary considerably according to species ; in
the % they occupy the whole of the ventral segments from the fourth
or fifth inclusive ; on the fifth and sixth segments the stigmatiform
impressions are very distinct, except in the division Gynaptera^ where
they are nearly obsolete ; in the 9 the light organs occupy the middle part
of the ventral segments, and exhibit themselves mostly as a flat elevation
on the fifth segment. The stigma-like impressions are barely or not visible
in the 9 , which may thus be easily distinguished from the 9 of the species
of the preceding genus. Some of the species are among the most abundant
and beautiful of our lightning bugs, though less gregarious than Photuris.

exist, but with a purely normal respiratory function. It may be affirmed with
great probability, that these impressions are homologous with the ventral setigerous
pores or fovese of Carabidse and Staphylinidse, which bear the so called ambulatorial
setse. In Lampyridse these fovese are conspicuous only in this and the following
genus (Phoiinus), so far as the genera occur in our fauna.

PI.EOTOMUS Lee.

The development of this genus has been traced by Mrs. V. 0. King,
Austin, Texas ; and the resuUs of her observation are pubhshed in
Psyche iii, 51 — 53. For a good series of specimens I am indebted to
Mrs. King and Mr. Belfrage. I have separated the 9 found by Mr.
W. 31. Davis in the mountains of Kentucky as a distinct species, on
account of the much greater length of the prothorax ; the % is un-
fortunately unknown. The light organs are brilliant in the $ , less so in
the S . The prothorax is finely carinate and the elytral costae distinct.

As there is no other character available at present for the distinction
of the second species, a longer description is unnecessary.

Group 4. — Luciolx.
The eyes are large, convex and widely separated above and beneath in
both sexes, not conspicuously larger in % ; the head is rounded, narrowed
behind and not retractile ; it is but partially covered by the prothorax,
which is, however, of the usual hood-like form and rounded in front.
The antenna) are longer than one-half the body, filiform, slender, not
compressed, inserted near the anterior margin of the front, and moder-
ately approximate ; the second and third joints are about equal, and
together are as long as each of the following joints.

The sexes are similar in form with long elytra and well developed
wings ; the light organs occupy the whole of the fifth and following-
segments ; stigma-like pores are not obvious, being situated at the base
of the fifth and sixth segments and less strongly marked than in Pyracto-
mena and Photinus % . The seventh ventral in 9 is ojjtusely triangular ;
in % the fifth and sixth are broadly emarginate, the seventh is smaller
than in 9 , sinuate at the sides and prolonged at the middle, the eighth
is a little wider and longer than the prolongation of the seventh. In our
species the outer (or anterior) claw is cleft at tip. The prothorax and
elytra are densely rugosely punctured, the former is yellow with a black
stripe or spot, each side of which the disc is red ; the latter have the
whole margin and frequently a discoidal stripe pale. A single genus
occurs in our fauna with limited representation.

which is exposed. The eyes are convex, prominent, and widely sepa-
rated ; the antennae are not approximate, inserted in front and inside of
the eyes, and are plumose or flabellate in the S ; ( $ unknown). The
mandibles are long, slender and curved, the labrum connate with the
front, small in Pterotus, large and emarginate in Phengodes ; the middle
00X33 are contiguous, the metasternum between them being narrowly
carinate ; the side pieces of metathorax are broad and diagonally divided.
The gula is deeply impressed or excavated in all the genera.

I may add that the antennae are shorter in the la.st two species, being-
less than half as long as the body, while in the others they are nearly
two-thirds as long. As there are no other conspicuous differences than
those mentioned in the table, longer descriptions are unnecessary, and
would only mislead the student.

ZARHIPIS n.g.

This genus agrees with Fhengodes, in all respects except the following :
The head is less deeply concave between the eyes, and not transversely
constricted or impressed behind ; epistome elevated above the labrum ;
the elytra are nearly as long as the abdomen, slightly dehiscent and
rounded at tip ; the third as well as the fourth tarsal joints are furnished
beneath with a distinct membranous sole ; the seventh ventral is acutely
emarginate ; the sixth segment is also emarginate, but the seventh is cleft
almost to the base, and the lobes sometimes overlap behind presenting the
appearance of a narrow closed slit, in which the basal part of the eighth
ventral is visible.

These are small, slender insects, having the antennae biramose, or serrate
but not flabellate as in Phengodini, the branches being less slender. The
eyes are small, lateral and convex ; the epistome is somewhat convex, and the
labruni is small and indistinct ; the mandibles are acute but not prominent.
The maxillary palpi are long, the labial very short ; the gula is less deeply
excavated than in Phengodes^. The side pieces of metathorax are long
and narrow, diagonally divided, with the epimera exposed. The elytra
are short, dehiscent, and rounded at tip.

In this genus the labrum is small and indistinct, and the epistome
slightly convex, more advanced than in the two preceding genera ; the
head between the eyes is flattened, scarcely concave ; the gula is much
less excavated, and the maxillary palpi are long, flattened, not slender,
with the last joint triangular or rather securiform. The antenna) are not
longer than the head, biramose, with the branches shorter and stouter,
though still flexible. The eyes are lateral, moderately large and convex.
The flanks of the prothorax are acutely margined, flat, not concave, the
edae (if the disc is not maroined nor flattened. The metasternum is
longer than usual, with narrow side pieces, but the epimera are large.
The elytra are less than one-half as long as the abdomen ; dehiscent and
rounded at tip, without distinct epipleurae. Legs slightly compressed ;
joints 1 — 4 of tarsi gTadually a little shorter and narrower, fourth small,

I am also indebted to Mrs. King for a larva of Mastinocerus, of slender,
cylindrical form and pale color. It was feebly luminous, and lived upon
small snails. The perfect insect is thus mentioned in a letter, the observa-
tions being made upon a specimen attracted by the lamp : " June 4th saw
running rapidly over the table near a lighted lamp, a small Coleopter ;
it was twisting its abdomen up over its wings, and evidently trying to
straighten them out, as they seemed moist and twisted at their ends. The
general appearance suggested Mastinocerus, and acting on this thought,
I captured it and sat up till a late hour to be assured of the truth. The

AMERICAN COLEOPTERA. 41

insect was in a small vial and moved quickly. It gave out light con-
spicuously from the head, feebly from the anal end, and still more so from
about the base of the abdomen. The light seen in the head, though
visible in the dark as a round spot, yet when taken into a room obscurely
lighted was invisible from above ; but when the insect was suddenly
thrown upon its back a light no larger than a pin point was seen just
about the junction of the head and prothorax."

C ENOPHEKGrS n. g.

I have established this new genus upon a small Californian species,
which greatly resembles in appearance Mastinocerus fexanus, but differs
by the antennje as long as the head and prothorax ; the prothorax a little
longer than wide, with the lateral edge distinct only behind the middle,
and quite obliterated in front. The maxillary palpi are elongate and
slender, with the last joint long and cylindrical. The seventh ventral
segment is more broadly emarginate, and the eighth comparatively larger.
In all other respects it closely resembles 3J. texinius, except that the
sculpture is finer.

TYTTIIOXYX Leo.

The well-known but not al)un(laiit species which is the type of this
genus, is of somewhat difficult location. Its appearance would indicate a
relatio iship with the Malthini group of Telephorida;, but after a careful
study of its characters I am inclined to believe that its true position is
near Maafinorerus and Cenophenr/u.<<, with perhaps a closer tendency
towards Drilus than is exhibited in those genera.

The characters have been sufficiently given l)y me in other places to
permit of the easy recognition of this genus, but in order to substantiate
the opinicm above expressed it is now necessary to go into greater details.

Head broader than long, deflexed, eyes small, rounded, convex, promi-
nent, finely granulated ; epistome rounded in front, connate with the
labrum and covering the mandibles which are curved, slender at tip,

broadly toothed about the middle ; palpi with the last joint oval, obliquely
truncate, so as to appear pointed and aciculate at tip ; ligula and mentum
small, supported on a broad gular peduncle which is concavely impressed
behind ; sutures widely separated. Antenna long, broadly compressed,
strongly serrate, joints triangular, second but one-half as long and one-
half as wide as the third, outer joints ( S ) longer, narrower and more
prolonged at tip than the lower joints. Prothorax transverse, truncate
in front, broadly rounded behind, sides short, inflexed flanks very narrow ;
under surftice of prothorax membranous, with the exception of a very
very narrow collar which supports the front legs ; coxae and trochantins
large. Middle coxae contiguous. Side pieces of metathorax broad, nar-
rowed and pointed behind, not sinuate on the inner margin, epimera ex-
posed. Elytra one-half as long as the abdomen, rounded at tip ; epipleurae
narrow, but distinct for one-half the length. Scutel broad, slightly emar-
ginate behind. Wings straight, extending along the dorsal surface of the
abdomen. Legs feeble, claws small, simple.

Sub-f\imily III.— TELEPHORID^E.

The insects of this sub-family are -closely related to the Lampyridse
genuini, but are easily known by the stronger development of the mouth
organs, the smaller size of the eyes, which permits the antenn;^ to be
widely separated at the base, and by the straight, or nearly straight out-
line of the inner side of the metathoracic episterna.

Light organs do not exist in any of the species, and the sexes are very
similar in form, differing, at most, by the length of the antenna? and the
outline of the sides of the prothorax. Sexual characters are also seen
in the last segments of the abdomen, especially in Chau/iognafhus and
Mdlthodea ; in the latter genus the claspers assume large size and great
complexity. In a few instances tibial and tarsal characters distinguish the
sexes, and in Biiany species of Telepliorus the; ungues are quite different.

I have excluded the singular genus Ometliea from this sub-family. It is
not a Lampyride, but where it may be suitably placed I do not know.

Two tribes may be recognized in our fauna :

Mentum very long, wider in front CuAtiLioGNAXHiNi.

Mentum sm;ill, quadrnte TELKPHoniNr.

AMERICAN COLEOPTERA. 43

Tribe 1. — Chauliognathini.
This tribe consists of but one genus represented in our fauna by a
moderate number of species. They are much more numerous in Tropical
America, but so far as I am aware do not occur in other countries.

CHAUI.IOGIVATHIIS Hentz.

This genus differs from all others in our fauna not only by the
elongated head, and singular structure of the maxillary lobe which has
a long extensile and contractile fleshy filament, but also by the peculiar
arrangement of the under surface of the prothorax, and the sexual
characters of the % .

The prosternum is but feebl} developed, and separated by membrane
from the surrounding parts. The trochantin is very large, triangular and
flat, and the inflexed flanks wide and concave ; the two gular plates at
the anterior margin of the prosternum are large and prominent, dipping
perpendicularly inwards. The mentum is very long and narrow, a little
broader in front ; the gailar sutures run from the hind angles of the
mentum obliquely inwards, and coalesce on the median line, almost to
the hind margin of the lower floor of the cranium.

The last ventral segment of the % is elongate-oval, convex, and of
firmer corneous consistency than the other segments; the penultimate
ventral is emarginated broadly and deeply by the convexity of the last
segment ; from the terminal opening between the last ventral and dorsal
is frequently seen protruding a pair of claspers, of slender curved form,
hooked at the end and fringed on the inner margin with spines, thus
resembling the inner lobe of the maxillae of Carabidfe.

These characters and those already given by me in the Classification
(p. 186), abundantly indicate the propriety of recognizing this type as a
separate tribe.

In several species the antennae in the % are longer than in the 9 ,
and the outer joints are somewhat broader ; but there is not sufficient
difference in this respect to be worth indicating among the specific
characters in the tahle.

AMERICAN COLEOPTERA. 45

Group 1. — Podahri.
Although as will be seen below, the species of this group differ in the
form of palpi, as well as in the tarsal claws, they seem to me to indicate
but one natural genus. They are more numerous in the northern part
of the Continent, and gradually fade out towards the tropics.

FODABRIJS Westwuod.
In this genus the gular sutures are confluent at the median line, and
the head is prolonged and narrowed behind the eyes, so as to form a
distinct neck not covered by the prothorax, which is nearly truncate, or
even s(jmewhat emarginate in front. The seventh ventral segment of
the % is truncate, and the eighth is exposed, sometimes triangular,
sometimes with parallel sides and obtusely rounded at tip. The seventh
ventral of the 9 is triangular, subsinuate each side near the tip, which
is frequently slightly nicked, though I have not found use for this
character as a specific distinction, since from the drying of the specimens
it is difficult to observe. The three divisions are so diff"erent as almost
to entitle them to rank as distinct genera, though some forms link them
together rather closely.

The numerous spi^cies of this giMiiis prestait at times sexual differences
in the form of the prothorax and the tarsal claws, which render the
distinction of species somewhat uncertain. They are likewise of variable
color and soft texture, so that in dried specimens the form cannot be
ac-curati'ly defined. The present table may th.-refore be considered, while
an improvement upon the crude work of my first synopsis,"}" only as a

Group 3. — Maltliini.
The species of this group are of small size and weak structure,
remarkable chiefly for the short elytra, which leaves the wings partly
exposed and folded along the dorsal surface of the abdomen. I have
modified the group as exposed by me in Classification Col. N. Am., by
removing Ti/tthonyx which seems to have no relation to the other genera
and to resemble them superficially merely by the abbreviated elytra.

The wealth of variation in sexual characters is greater in this group
than in almost any other in Coleoptera. In Ichfht/urus it afifects the middle
legs of the S , and in MnltJwdes the last abdominal segments of both
sexes, and the forms of the claspers are ([uite as complex as those repre-
sented by Baron R. Osten Sacken in the Tipulidas, with short palpi, Proc.
Acad. Nat. Sc. Phila. 1859, pi. 3 & 4. The species are probably numerous
but have not yet received much attention from collectors. The European
s])ecies, which run somewhat parallel with ours, have been excellently

make a satisfactory comparison between it ami Tri/pherus Lee. {Lijyerus
Kiesenw. ), wliich is somewhat unfavorable to the retention of the hitter
as a distinct genus, though in the present condition of nomenchiture it
cannot be properly suppressed. The enormous inflation of the middle
thighs of the % in /. discoidalis, the extremely prolonged spinil'orm
trochanters, and the very short tibi;e of the same pair of legs would lead
one on superficial inspection to regard the two insects as distinct generic
types. But I find that in the S of T. latipcnnis the middle trochanters
are larger than in the 9 , ])ointed at the end and angulated or even toothed
near the base ; the middle thighs are also decidedly thicker than in the
9 , though there is no difference in the tibiae. The last abdominal seg-
ments are similarly modified in the two species, though much more strongly
so in the Oriental than in the American species. In the former the last
dorsal is emarginate or bilobed, and is moreover deeply excavated beneath ;
the seventh ventral is truncate behind, and the eighth narrower and
mucli smaller. In T. latipennis the last dorsal is only broadly emar-
ginate, and there is a small anal segment ; the seventh ventral is deeply
emarginate, the eighth is more complex in arrangement with some small
processes, which are difficult to describe, and as there is but one species,
quite unimportant for the recognition of the same. The eyes in both
genera are large and prominent in the % .

* This generio name should probably be rejeoted for the speoies here mentioned ;
it was proposed (Ann. Soo. Ent. Fr. 1st, ii, 136), for species with ramose antennae;
the universally known and common species, atra Fabr., is not mentioned among
them, and is referred to by Laporte under Lucernuta, the second division of
Photinu.t, as No. 25, P. laticorni.i, ibid. 144. It is quite evident that the super-
ficially observed characters used by him, like those of Motschulsky, can have no
significance in a system like that which I have here attempted to introduce, for
the very next species of Photinus {Lucernuta), is described as having a " luminous
spot at the middle of the fourth ventral segment." This position of the light-
organ, barring the error in the numbering of the segments would place at least
that speoies of Lucernuta in the neighborhood of Pyractomena. In the confusion
of nomenclature thus produced it would perhaps be easier to retain for our species,
and for as many from tropical America as are found to be congeneric with them,
the Dejeanian name Lychnuris, fir.st defined by me in Proc. Acad. Nat. So. Phila.
ii, 332. Since, however, I am neither a "purist," nor " resurrectionist," but an
humble conveyor of thought, endeavoring only to state distinctly the relations
of the objects of which I have occasion to write, I leave this and many similar
questions for those whose tastes lead them in another direction.

* I have given references only to the original description and to two others of
recent date. The European synonymy of this introduced species need not be
imported into our literature.

fThe Mexican Lump, tritineata Say, (Bost. Journ. Nat. Hist, i, 157; ed. Lee ii,
634), with which Motschulsky compares this species, is evidently quite different to
it in havinff two or three lines on each elvtron vellowisli.

In concludiiiii' this paper, I have only to regret, that although, several
of my friends, who have collaborated with me, for the procuring of
material to render it as perfect as possible, the position and affinities of
the tribe Phengodini must still remain uncertain, in consequence of the
ignorance in which we remain in regard to the habits of the species, and
the form of the females. It may be inferred from the observations of
Mrs. King on the larva and male imago of Mastinocerus that they are
luminous in all stages of development. This inference must, however,
be confirmed by those who have the opportunity of observing in a living
condition the genera and species of the tribe, which as will be seen in
the foregoing pages are widely distributed. The male of Pterotiis, as
I have been recently informed by Mr. Rivers, flies in the evening twilight,
but I have not yet learned if it has any luminous power.

ReTision of the species of P©L,YPHY1.1.A of the United

States.

BY GEORGE H. HORN, M. D.

The generic characters of Polyphj/lla have been so often given that
it is unnecessary to repeat them here. In the " Check List," Mr. Crotch
has separated our species from those of Europe under the name of
31acraiwxia, but no reason is apparent to me for such a course.

The males are much more abundantly found than the females the
latter rarely flying, while the males are often seen circling in flight in
considerable numbers over the spot where the female may be.

As the "males are the more abundant and as they present structural
characters by which they may be distinguished, the following table is
based on that sex alone.
Anterior tibiae tridentate.

Body above distinctly scaly; clypeus trisinuate Hammondi.

Elytra with scale-like hairs; clypeus truncate cavifroiis.

Anterior tibise bidentate.

Clypeus trisinuate, the lateral angles distinct.

Head and thorax with moderately long erect hairs and very few scales.

crinita.

Head and thorax scaly with short hairs only decenilineata.

Clypeus truncate or arcuate, the angles not prominent.

Elytra distinctly vittate occidentalis.

Elytra with irregularly placed denser spots variolosa.

Anterior tibiae with the outer apical angle alone prolonged. (That of the female
bidentate) gracilis.

P. Hammoudi Lee, Journ. Acad. 1856, p. 228; subvittata Lee. loc. cit.
p. 229.-Clvpeus trisinuate, the lateral angles prominent, vertex with short erect
hairs. Thorax with few erect hairs in front, surface very sparsely scaly and with
three denser vittte, the median more distinct; hind angles either distinctly rect-
angular or obtuse. Elvtra very sparsely scaly, the scales in indistinct vittse, the
sutural more dense. Bodv beneath clothed with moderately long fine yellowish
hair, abdomen sparsely scaly, scales denser along the posterior borders of the
segments. Length .96—1.16 inch; 24—29 mm.

Jfa/e.-Antennal club 7-lamellate, arcuate or sigmoid, more than twice as long
as the stem. Anterior tibiae tridentate, middle tibia, bispinous on the outer edge,
posterior tibise with two short oblique ridges.

Fema/e. -Angles of clypeus not prominent. Antennae short, the club not more
than half the length of the stem, composed of fine joints forming a rather compact
mass, the contiguous joint of the stem half as much prolonged as those ot the .club.
Tibial characters as in the %.

The form subvlffnfa differs only in having the elytral vittae a little

better marked.

Occurs in Kansas and northern Texas. For a specimen of the
female which seems to be rare, I am indebted to Prof. F. H. Snow
of Kansas.

P. cavifrons Lee, Proc. Aead. 1854, p. 222; Journ. Acad. 1856, p. 228.—
Clypeus truncate in front, margin moderately reflexed, angles not prominent.
Front flat coarsely punctured and with few, short, semi-erect hairs. Thorax with
very few erect hairs in front, surface sparsely clothed with scale-like hairs which
are denser in the median sulcus, lateral vittse indistinct. Elytra sparsely clothed
with scale-like hairs forming a subvittate appearance. Body beneath with moder-
ately long hairs, abdomen with elongate scales sparsely placed. Length .96 inch;
24 mm.

Male. — As in the preceding species.

Female. — Unknown.

This species could be confounded with the preceding only. It has a
somewhat more robust facies and diflPers in the form of the clypeus and
the surface vestiture.

My specimen was collected at Ehrenberg, Arizona ; those in Dr.
Leconte's cabinet are from an uncertain locality in the same Territory.

P. deceniliiieata Say, Journ. Acad, iii, p. 246; Lee. loc. cit. 1856, p. 229. —
Clypeus trisinuate, sometimes feebly, the angles distinct. Vertex flat with few,
short, semi-erect hairs, densely scaly at the sides. Thorax with a few erect hairs
along the margin only, surface sparsely clothed with white scales, forming a denser
vitta in the median impression and on each side. Seutellum densely scaly. Elytra
scaly, the suture three nearly entire vittse and a short subhumeral line densely
clothed with white scales, the remainder of the surface sparsely clothed with scales
which are often yellowish. Pygidium rather densely clothed with narrow elongate
scales. Body beneath as in Hammondi. Length .96 — 1.44 inch ; 24 — 36 mm.

Male.— Antennse as in Hammondi. Anterior tibite bidentate. Middle and pos-
terior tibise with one short spine a little below the middle.

Female. — Anterior tibiae tridentate, middle and posterior each with two short
spines on the outer edge. Antennal club 5-lamellate, a little longer than half
tbe stem.

Specimens occasionally occur in which the vittae are somewhat irregular
or interrupted.

Occurs from Colorado westward to California.

P. Ci'iiiita Lee, Journ. Aead. 1856, p. 2.30.— Very closely resembles the pre-
ceding sj)eeies and differs in having moderately long, erect hairs on both the head
and thorax. The latter has the usual scales replaced by very narrow scale-like
hairs, even the three vittpe can hardly be called scaly. On the elytra the scales
are also more liair-like while they form a style of ornamentation resembling that
of denemlineatn. Length .88 — 1.04 inch; 22 -26 mm.
Sexual characters as in decemhneata.

This species appears to bear the same relation in the matter of vesti-
ture to the preceding that cavifrons does to Hamwondi.

fig. 7; Burm. Handb. iv, 2, p. 408; Lee. loc. cit. — Clypeus truncate or slightly
arcuate in front, the angles obtuse % or rounded 9 • Head sparsely clothed with
recumbent scale-like hairs. Thorax with median sulcus feeble, surface sparsely
pubescent with the vittse scarcely more distinct. Elytra sparsely clothed with
recumbent pubescence, with the suture and three nearly entire (but feebly marked)
vittse more densely clothed, subhumeral short line absent. Pygidium pubescent
and with rather long erect hairs. Body beneath with moderately long hairs,
abdomen sparsely pubescent. Length .88 — 1.00 inch; 22 — 25 mm.

Male. — Sexual characters as in decemlineata, with the spine on the outer side of
the middle and posterior tibife very feeble.

Female. — As in deceynlineata except that there is but one short oblique ridge
on the middle and posterior tibise, and the anterior tibiee are bidentate as in
the male.

Thi.s species is the only one in wliicli the anterior tibia? are known
to be similarly dentate in the two sexes.

Occurs near the sea coast in the Southern States, my specimens are
from near Wilmington, N. C. The females are said to be more abundant
than the males, a fact at variance with the usual habit of the genus.

P. variolosa Hentz, Trans. Am. Philos. Soc. iii, p. 256, pi. 2, fig. 5 ; Lee.
loc. cit. p. '2?,\. — Clypeus arcuate or subtruncate, angles rounded. Head sparsely
clothed with short erect hair. Thorax sparsely punctate and with few recumbent
hairs forming a denser vitta in the deep median sulcus and indistinct vittfe at the
sides. Elj'tra sparsely clothed with scale-like hairs denser along the suture and
forming irregular patches in place of the vittse of the preceding species. Pygidium
sparsely pubescent. Body beneath with long hairs, abdomen sparsely and finely
pubescent. Length .84 — .90 inch; 21 — 23 mm.

Male. — Sexual characlers of occidentalis.

Female. — Sexual characters of decemlineata.

It will be observed that the females of all the species of this genus
have a shorter clypeus than the male, but in this species the differ-
ence is more especially marked. The hind tibiae are also broader in
the females. ,

Occurs near the sea coast from Massachusetts to New Jersey.'

P. $;racilis n. sp.— Form rather slender, pale brownish testaceous. Clypeus
truncate, angles prominent and sides convergent posteriorly %, or with angles
rounded and sides divergent posteriorly 9 • Surface sparsely clothed with re-
cumbent elongate scales. Thorax more than twice as wide as long, sides strongly
arcuate at middle, margin crenulate, median impression of disc very feeble, surface
sparsely clothed with whitish scale-like hairs forming three distinct denser vittas.
Elytra sparsely punctate and sparsely clothed with whitish elongate scales, a lateral
denser vitta distinct, the disc with irregular spots forming two very indistinct vittse.
Body beneath with long hairs, abdomen sparsely pubescent. Pygidium sparsely
pubescent. Length .74 inch ; 10 mm.

Male.— Aniennte as in variolosa. Anterior tibiai with the outer apical angle
alone prolonged, middle and posterior tibire without trace of spine or oblique ridge
at middle.

76 GEO. H. HORN, M. D.

Female. — Anteniife as in variolosa. Anterior tibise bidentate externally, middle
tibia with a very distinct oblique ridge, posterior with a feeble trace of ridge.

This species might be mistaken for a debiUtated form of variolosa^
but its more slender form and the sexual characters mark it as abun-
dantly distinct.

Occurs near Jacksonville, Florida ; collected by W. H. Ashmead.

Notes on EI^ATERID^. CEBRIOIVID^., RHIPICERID^
and OASCYLLID^.

BY GEORGE H. HORN, M. D.

ELATERID.5;.

The genera of the above family to which especial reference is made
in the following pages, are those considered most closely allied to the
Cebrionidae, so close in fact that they may be considered as entirely filling
the gap which has been supposed to exist between the two families.

The notes are necessarily short, full descriptions of the males having
already been given, the females as far as known claim more attention
and it is hoped that the accompanying figures will give a better idea of
these remarkable insects than description alone.

The females of Apla.^tus and Eufh^sariius are remarkable in having
the elytra shorter than the abdomen, but not equally so in all as will be
seen by an examination of the figures.

In the former genus there are but six visible ventral segments while
in Eiitliiji^ninnx there are seven. In the 9 of E. lautus however, the
abdomen is so extended by the completeness of the egg development,
that the membranous segment which is usually subcoxal becomes visible
and eight segments appear. In all the females there is a similarity on
the dorsal surfiice of the abdomen, eight segments being quite distinctly
visible. Nor is this number peculiar to the female, the male having the
same but the segments are more membranous. In an examination of
several other true Elateridas the number of dorsal segments is eight,
therefore the presence of this nvimber in the females of Euthijudnius and
ApldstiiR must be dismissed from the category of remarkable characters.

APHRICUS Lee.
Fnmt slightly concave, anterioi'ly slightly arcuate, margined. Labrum short,
transverse, emarginate and retracted, the suture distinct. Mandibles moderately
prominent and toothed a little in front of middle. Maxillary palpi rather slender,
the last three joints subequal, the terminal very little broader at tip. Antenna?
sknuler not serrate, two-thirds as long as the body, eleven-jointed, last joint with
a distinctly articulated short accessory piece, first joint obconical, slightly curved,

AMERICAN COLEOPTERA. 77

second small, third a little longer, fourth as long as first, 4 — 11 gradually more
elongate. Eyes rather large, round and prominent. Tarsi slender, first joint on
each foot shorter than the second and about equal to the fourth.

A. californicus Lee. — Pieeo-testaceous, sparsely clothed with greyish pubes-
cence. Head coarsely and densely punctured. Thorax a little longer than wide,
sides in front arcuate, posteriorly slightly sinuate, lateral margin rounded without
limiting edge, hind angles slightly divergent and with an extremely fine carina,
surface sparsely punctate in front and nearly smooth posteriorly. Elytra striate,
striae with coarse and deep, closely planed punctures, intervals finely punctulate,
the fifth subcarinate at apical third. Body beneath very sparsely punctulate.
Length .24 inch ; 6 mm. Tl. II, fig. 6.

Of this insect we know the male only. The femtile probably does not
differ greatly. The general aspect is that of an elongate Cardiophorus.

Occurs from San Diego to Owen's Valley, California ; but very rare.

APL.ASTUS Lee.
The species have been so recently the subject of a review that I
merely repeat the table given in Trans. Am. Ent. Soc. 1874, p. 24,
which applies to males only.
Third joint of antenna similar in size and shape to fourth.

Antennffi slender, feebly serrate, three basal joints only pilose ; sides of thorax
parallel not margined, hind angles strongly divergent. PL I, fig. 9.

angusticullis Horn.
Third joint always much smaller than fourth, sometimes globular never triangular ;
antennae with short erect hairs.
Thorax not margined.

Antennfe strongly serrate, joints 2 — 3 very small, equal, together slightly
longer than half the fourth.

Elytra scarcely striate, thorax sparsely punctate teuuirorinis Horn.

Elytra moderately deeply striate, thorax coarsely and moderately densely

punctate corynibifoides Horn.

Antennee serrate, joint three more than twice as long as second, the two

together nearly as long as the fourth speratus Lee.

Thorax distinctly margined, at least near base.

Antennae stout, strongly serrate. PI. I, fig. 6 optattis Lee.

Antennse more slender, feebly serrate niolestus Horn.

The body is always fully winged in the males. In all the species the
constriction of the eleventh joint of the antennae near the tip is quite
evident except in molestus.

There are but two females known, one of which belongs with reasonable
certainty to sperntus, the other probably to optatus. It may be needless
to say that the characters given for the sexes (loc. cit. p. 26), are not
valid, they are evidently variations of the male only.

A. speratus 9 Lee— Parallel, rufo-piceous, feebly shining, sparsely pubes-
cent, body feebly winged. Head moderately densely and coarsely punctate.
Antennfe passing slightly the middle of the thorax, subserrate, first joint stout,
second small, round, third a little longer, fourth slightly longer than third, 4—8

(15)

gradually decreasing in length, ninth not longer than second, tenth and eleventh
longer, less serrate, the latter slightly constricted at tip. Thorax not longer than
wide, slightly broader at base than apex, sides nearly straight, hind angles feebly
divergent, carinate, surface not densely punctate, a feeble median line posteriorly,
an oblique moderately deep impression on each side at end of carina. Elytra
about two and a half times the length of the thorax, shorter than the abdomen,
striate, intervals alternately broader, the narrower intervals slightly more convex
near the tip, surface moderately densely punctulate and near the tip somewhat
wrinkled, apex obliquely prolonged. Prothorax beneath densely punctured at
middle, sparsely at the sides, metathorax sparsely and finely punctate. Abdomen
shining, very sparsely finely punctulate. Length .56 inch; 14 mm. PI. I, fig. 8.

The maxillary palpi in addition to the normal four joints have a small,
narrow joint at the end of the fourth. The structure of the antenna?
above described is also somewhat abnormal, and I observe on one side
that the eighth and ninth joints are connate and on the other mobile.
The impressions in the thorax near the tip of the carina are probably not
permanent in their occurrence, as I observe a variation in this respect in
the two females of one Euthi/sanms before me.

The abdomen beneath is composed of six segments, the last being
retractile and the first and fifth equal to the two adjacent ones. From
the female of Euthi/aanius this differs in having one less segment to the
abdomen and one less (eleventh) joint in the antennae.

The reference of this female to Aplasfus speratus is not without a little
doubt, but from its size, general aspect, locality of occurrence, I think
the propriety of the reference will be fully confirmed in the future.

One specimen, Marin Co., California ; in the cabinet of Mr. Ulke.

A. optatus 9- — Similar in form and sculpture to the preceding female but
with the thorax more nearly square and much more convex. The hind angles
liave a short carina and the surface sparsely punctured a little more densely near
the anterior angles. The elytra are striate, the intervals convex, the surface rather
densely punctulate, and the apex less prolonged. Abdomen as in the preceding.
Length .84 inch; 21 mm. PI. I, fig. 7.

I refer this female to optatus from its size and the sculpture of the
elytra, the preceding female is referred to speratus from the very distinct
alternation of the elytral intervals. In this female I do not detect the
small appendicular piece on the tip of the maxillary palpi nor is there
that apparent deformity of the antennas.

One specimen, in the cabinet of Mr. Ulke. This is the type of
Ananiesus convexiroUis Lee.

FL,ASTOCERUS Lee.
This genus was originally described by Dr. Leconte, (Trans. Am.
IMiilos. Soc. X, p. 502), on a species from California, P. Schaumi'i, at
thi' same time remarking that a " specimen of this insert was sent by

AMERICAN COLEOPTERA. 79

me to Dr. Schauin, who pronounced it strictly congeneric witli Callir-
hipis angulosa Germ., which forms the type of the unpublished genus
Plastocerus." Lacordaire and, following him, Duval both call angu-
losa the type of the genus, a position which cannot by any means be
sustained, as Dr. Leconte did not see that species and probably has not
even studied it since that time.

This would be a matter of very little moment if anguloaa and
Scliaumii were really congeneric, of which I have very considerable
doubt from the structure of the labrum and the antennae and the form
of the mandibles. I have not seen the angulosa and can go no further,
and leave the development of the matter to European students.

Of our own species I have seen and studied many specimens, and
conclude that all the forms constitute but one species in which three
varieties may be indicated.

Hind angles of thorax stronglj divergent and earinate.

Thorax rather narrow not very densely punctured. PI. II, fig. l...Scliaiiiiiii.

Thorax as broad as long, coarsely and densely punctured. PI. II, fig. 2...1i'siter.
Hind angles not divergent feebly earinate.

Thorax narrow coarsely and densely punctured. PI. II, fig. 3 macer.

In the accompanying plate I have endeavored to represent the three
characteristic forms with the details of sculpture and two additional
outlines. There is no constancy in the form of the thorax nor in
the sculpture of the elytra all intermediate degrees occurring in both
particulars.

The figure given of frater (PI. IT, fig. 2), is undoubtedly a female,
and I find no important difference from the male excepting in the struc-
ture of the antennas and the last ventral segment. In the antennae the
branches are about half the length of those of the male and not ciliate
at the sides, and with a few short ciliae at tip only. The last ventral-
segment is merely shorter and broader than in the male.

If this is really the female, and I think there is no dbubt, the species
shows a wide divergence from Euthysanius in this sex, the males of the
genera differing merely in the number of the joints of the antennae.

Occurs in southwestern maritime California.

In fig. 4, will be found an illustration of a curious monstrosity which
explains itself.

EUTHYSANIUS Lee.

The form of the labrum appears to have no value specific or otherwise,

it may be truncate, sinuate or even triangularly emarginate and in the

same species. There appear to be but two species in both of which

I observe an amount of variation which, with fewer specimens, would

80 GEO. H. HORN, M. D.

probably cause further subdivision, but it will be observed in all these
aberrant and rather soft Elateridse., that there is a certain elasticity in
specific characteristics which must always be taken into account.
The two species are :

Terminal joint of antennse decidedly shorter than the branch of the eleventh ;

thorax always longer than wide at middle lautus Lee.

Terminal joint as long as the branch of the eleventh j thorax usually as wide at

middle as long pretiosus Lee.

E. LAUTUS S Lec. — The accompanying plate shows what I consider
merely varieties of this species, and it is well here to remark that the
impressions in the thorax of one form and their absence in the other is
not by any means constant. The typical form (fig. 1), is usually darker
in color than the other, a little stouter in form and with the thorax
a little more coarsely punctured. It is possible that the discovery of the
female will show the variety (fig. 2), to be a distinct species, and if so
the female will probably have elytra less short than in the true lautus,
and more nearly squarely truncate at tip. Length % .80 — .92 inch ;
20—23 mm. PI. I, fig. 1, 2.

Occurs at San Diego, San Luis Obispo, Tejon and Owen's Valley,
California.

E. Isintns f • — Elongate, cylindrical, slightly depressed, rufous, moderately
shining, sparsely pubescent, feebly winged. Head moderately densely and coarsely
punctate. Antennse passing slightly the middle of the thorax, serrate, first joint
obconical, 2 — 5 small, nearly equal, not angulate in front, 6 — 11 longer with the
free angle becoming gradually longer, twelve as long as the branch of the eleventh
and slightly curved. Thorax nearly square, very little narrowed in front, hind
angles slightly divergent and carinate, surface not very densely punctured and
with a depression and smoother space on each side in front and at middle pos-
teriorly. Elytra very little longer than wide conjointly and not extending beyond
the first dorsal abdominal segment, suture slightly separated the angle rounded,
ajiex obliquely truncate the outer angle rounded, striae deep and distinctly punc-
tate, the intervals convex sparsely punctate. Abdomen with eight fi'ee segments,
the last two slightly shorter than the others, surface sparsely and finely punctate
more densely on the sixth. Thorax beneath coarsely punctured at middle and
very sparsely at the sides. Metathorax very sparsely punctate. Abdomen more
shining not densely punctate. Length 1.44 inch; 36 mm. PL I, fig. 3.

In the only specimen I have seen which is a fully impregnated female
the abdomen is greatly extended even beyond what I have shown in the
figure, the connecting membranes between the abdominal segments both
on the dorsal and ventral aspects are nearly half the length of the
segments themselves, the abdomen is thus extended so as to equal very
nearly two and a half times the thorax and elytra together. The figure
is purposely drawn with less connecting membrane showing. There are

AMERICAN COLEOPTERA. 81

eight abdominal segments on the upper and lower faces, the first ventral
is however entirely membranous and almost concealed by the coxae.

The body is not apterous, but the wings are short and feeble.

One specimen, Fort Tejon, California ; in cabinet of Dr. Leconte.

E. PRETiosus % Lee. — This species excepting the antennae has more
the form of some of our Asaphes. The antennal character is the only
constant one for the separation of this from lautus. The thorax is
usually as broad as long but this is not constantly so. The surface is
however less coarsely punctured and at base more finely than in lautus.
Length .72 inch ; 18 mm. PI. I, fig. 4.

This species is the one referred to by Lacordaire, ( Genera iv, p. 233,
note), and through the kindness of Mr. Alexander Fry of London,
I have one of the specimens.

Occurs in the Coast Range region at and north of Santa Barbara.

E. pretiosns 9 .—Elongate, cylindrical, slightly depressed, rufo-testaceous,
moderately shining, very sparsely pubescent, body feebly winged. Head moder-
ately densely punctate, vertex slightly impressed. Antennfe slightly passing the
middle of the thorax, somewhat variable in structure. Thorax a little wider than
long, anterior angles rounded, sides very feebly arcuate, hind angles slightly
divergent and carinate, surface sparsely punctate and with a slight depression
each side at the end of the carina. Elytra as long or a little longer than the head
and thorax and covering the first two abdominal segments, sides arcuate, apex
slightly prolonged, suture dehiscent, striate, striae not punctate, intervals sparsely
punctulate. Prosternum coarsely punctate, the side pieces quite smooth, meta-
sternum and abdomen sparsely punctulate. Abdomen above very sparsely and
finely punctulate. Length .80— 90 inch ; 20—23 mm. PI. I, fig. 5.

The abdomen has eight distinct segments on the dorsal aspect and but
seven on the ventral, the first or subcoxal segment not being apparent
here, probably from the less extended condition of the abdomen.

The two specimens before me which are without any doubt the females
of £. pretiosus Lee, show a slight amount of variation. The specimen
in my cabinet from which fig. 5 was drawn has the thorax somewhat
more convex and the depressions of the thorax well marked, the elytral
striae quite deep and the intervals convex. In Dr. Leconte's specimen
the thorax more closely resembles that of the male, the striae are feebler
especially at base and the intervals less convex.

The antennae show the most important difierences. In my specimen
the penultimate joint alone has the anterior angle prolonged, while in the
other specimen (fig. 5 a), this joint and the three which precede are acute
in front and are about intermediate in structure between figure 5 and
that of E. lautus.

Two specimens froip the coast region of Cal., south of San Francisco.

CEBRIONID^.
Our genera in the books at present are three in number separated
as follows :

Labrum entirely connate with the front Anachilns.

Labrum separated by a suture from the front.

Anterior tibiae entire Cebrio.

Anterior tibiae emarginate externally Scaptolenus.

In studying the specimens of Anachilus in the cabinet of Dr. Leconte
all are without suture between the labrum and front, of the four in my
cabinet, one has a distinct suture, one less distinct, and two no suture
at all. Extending the study to Cebrio the same thing happens, and
specimens occur with a very distinct and probably flexile suture to others
where there is absolutely no trace whatever, the front and labrum being
perfectly continuous. As there is no other difference between Anachilus
and Gehrio the former must be suppressed.

The species of Cebrio have been separated by the form of the labrum
(emarginate or not), and maxillary palpi, (terminal joint equal to a shorter
than the preceding).

I have had before me. about three dozen, perhaps more specimens,
and besides observing that some have the labrum and front cari-
nate, the labrum has the anterior margin arcuate in some, truncate
in others or emarginate, and in several deeply triangularly incised,
and between all these forms every interniediate degree. The maxillary
palpi moreover do not possess that degree of difference in structure
which enables us to separate species thereby, and I have therefore been
compelled to abandon both the above mentioned characters and unite
all three species in one.

By the suppression of Anachi/us and the occurrence of one new, there
are three species in Cebrio in our fauna as follows :

Antennae distinctly serrate, the terminal joint rather suddenly constricted at tip;
elytra distinctly striate.

Presternum between the coxfe extremely narrow; mandibles very prominent
not capable of closure beneath the labrum inaiidibiilaris Lee.

Prosternum between the coxpe not linear; mandibles more robust and when
closed are in great part concealed at their base. PI. II, fig. 7...bicolor Fab.
Antennae feebly serrate, terminal joint not constricted at tip; elytra not striate.
Mandibles very feebly prominent estl'iatllS n. sp.

In a revision of the Cehriomdpe (Ann. Fr. 1874, p. 534), Chevrolat
retains the generic name Selenodon for our species, but for what reason
he docs not state nor can I find out.

€'. l»icj»Ior Fab. — Upper side brownish, piceous or castaneous, sparsely
|ml)esccut, beneath and legs testaceous. Head coarsely and densely punctate.
Thorax punctured but less densely than the head. Elytra moderately deeply

AMERICAN COLEOPTERA. 83

striate, striae coarsely punctured especially near the apex, intervals slightly
convex, densely punctate. Length .48— .80 inch, .909; 12—20 mm, 22.59.
PI. II, fig. 7.

The thorax is very variable in shape and convexity — usually nearly
square slightly narrowed in front, sometimes slightly transverse, the hind
angles are never strongly divergent. The disc may be either normally
convex or variously impressed. The mandibles when closed leave but a
small open space between them and the labrum.

C mandibularis Lee. (^nacAt7i<s). ^Moderately elongnte, fusco-testaceous,
sparsely pubescent. Head piceous or nearly black, moderately densely punctate.
Labrum transverse, feebly emarginate, usually pale in color, either connate with
the front without suture or with the suture more or less distinct. Mandibles
slender, prominent, and when closed leaving a wide open space between them.
Antennae moderately serrate, terminal joint deeply constricted at tip. Thorax
broader than long, sides moderately arcuate, hind angles acute, divergent, surface
moderately densely punctate. Prosternum extremely narrow between the coxae.
Elytra a little broader than the thorax, deeply broadly striate, striae coarsely
punctured especially near the apex, intervals densely punctulate. Body be-
neath paler than above and moderately densely punctate. Length .44 — .54 inch ;
11— 13.5 mm.

Of this species we know males only.

Occurs in Florida.

C estriatns n. sp. — Moderately elongate, pale brownish testaceous, finely
pubescent. Head moderately densely punctured. Labrum transverse, feebly
emarginate, suture distinct. Mandibles rather short, when closed not leaving a
space between them. Thorax nearly square, sides feebly arcuate, hind angles
short, acute, divergent, surface not densely punctate. Prosternum very narrow
between the coxae. Elytra a little wider than the thorax, surface not striate but
densely punctate and with faint traces of three discal costae. Body beneath not
densely punctate. Length .44 inch; 11 mm.

The antennae are less serrate than in the two preceding species and the
terminal joint is not constricted, this character with the absence of elytral
striae will serve to distinguish it.

One specimen, Texas.

SCAPTOI.ENITS Lee.

The species of this genus which occur in our fauna are from Texas.
In the Annales de la Societe Entom. de France, 1874, p. 523, Chevrolat
cites <S. 6r(2^^«^■ from Texas ? and p. 524, *S'. GaUfornicus from California,
while in the list of species p. 509, both are quoted from Mexico. I have
no doubt that they are really Mexican.

Three species are otherwise known to me.

Last joint of maxillary palpus as long or longer than the preceding. Last joint
of labial palpi longer.
Elytra rather deeply sulcate and suhcostulate liCCOntei Salle.

84 GEO. H. HORN, M. D.

Last joint of maxillary palpus very decidedly shorter than the preceding. Last
joint of labial shorter.
Elytra feebly subsulcate posterior to the basal fourth ; anterior tibiae with the
upper tooth strong; tibiae and tarsi pitchy black. PI. II, fig. 8.

ocreatns n. sp.

Elytra without traces of strise, moderately densely punctured : anterior tibice

with upper tooth feeble; legs pale brownish testaceous estriatus Lee.

S. Lecontei Salle {femoralis Lee.) — Piceous, moderately shining, elytra pale
eastaneous. Head piceous, deeply and coarsely punctate and with erect brownish
hairs. Thorax transverse, narrowed in front, apex slightly prolonged at middle,
anterior angles rounded, sides feebly arcuate, hind angles long, slender and not
divergent from the line of the sides, base lobed at middle, sinuate each side, surface
densely punctate and with erect brown hairs. Elytra elongate, gradually con-
vergent posteriorly, dehiscent at apical third, at base gibbous, surface moderately
deeply sulcate and subcostate, except at base and moderately densely punctulate,
sparsely clothed with short pubescence. Body beneath piceous, clothed with
yellowish hair, abdomen less punctate and with fewer hairs. Legs piceous, the
femora usually paler. Length .64 — .72 inch; 16 — 18 mm.

Only males are known. The anterior tibiae have the upper tooth
strong. The antennae are serrate. In both the maxillary and labial
palpi the terminal joint is longer than the preceding.

The color of the abdomen varies from piceous to testaceous, the seg-
ments often being piceous with the posterior edge of the segments paler.
In fully mature specimens the tibiae and tarsi are piceous the femora
paler, even pale yellow.

This is the most abundant species in Texas.

S, estriatns Lee. — Piceo-testaeeous, less elongate than Lecontei. Head and
thorax similar but with shorter yellowish hair. Elytra gibbous at base, without
trace of striae or costse, surface moderately densely punctate. Body beneath paler
than above and with the legs luteous. Length .56 inch ; 14 mm.

The anterior tibiae have the upper tooth rather feeble. In the max-
illary palpi the last joint is shorter than the preceding, the last joint of
the labial is also shorter but less distinctly so than the maxillary.

Occurs in Texas.

S. ocreatns n. sp. — Piceous, elytra testaceous, femora yellow. Head and
thorax piceous, moderately densely punctate, clothed with moderately long, erect,
yellowish hair. Elytra gibbous at base, pale testaceous, sutural and outer margins
near the apex bordered with black, surface faintly subcostate posteriorly and not
densely nor coarsely punctured, sparsely clothed with very short black pubescence.
Body beneath piceous, clothed with yellowish hair. Legs pitchy black, femora
yellow. Length .56 inch; 14 mm. PL II, fig. 8.

Very similar in form to esfriatns^ and therefore shorter and less
attenuate than Lecontei. The ant<?rior tibife have the upper tooth well
marked. The palpi are its in esfriufiis.

One specimen, Texas.

AMERICAN COLEOPTERA. 85

I find it impossible to place either of the hxst two species in any
of the groups suggested by Chevrolat, the characters given boing very
indefinite.

The maintenance of the Cebrionidfe as a family apart from the
Elateridse, is rather the result of universal agreement than from the
presence of any good reasons.

" The principal differences between this and the preceding family is in
the greater number (sis) of the ventral segments, the well developed tibial
spurs, the expansion of the anterior tibiaa at apex, and the close connection
between the front and labrum. By the intermediate forms of the group
Plastoceri, of the previous family, all the differences except those of the
anterior tibiae become evanescent ; and I place the Cebrionidfe as a distinct
family, only in deference to the views of the most distinguished foreign
authorities."

In the above quotation from Leconte (Classification p. 175), I fully
agree, and add that between the Plastoceri and Cebrio the dilatation of
the anterior tibiae is a matter of very little diff'erence and almost null.

Chevrolat seems more satisfied with his results :

" For the family of Cebrionites, I think I have united the elements
constituting a good classification and which present the most sharply
defined characters: males notably different from the females, winged,
elongate ; females apterous, short, stout ; the first having the antennje
slender, more or less elongate, flat, of variable form conical or triangular ;
the second having these members short, moniliform, gradually broader
externally ; the tarsi filiform in the two sexes."

I have no further criticism of this than to refer the reader to a
comparison of the males and females of Aplastus and Euthijmnhia.

From the above extracts, which form the substance of all that has
been said in defence of the retention of the Cebriqnidee apart from the
Elaieridse,^ it will be inferred that there are no characters at present
known which will separate these two families.

RHIPICERID^.

This family is represented in our fauna by two genera, Zemoa with
simple tarsi, Sandalus with lobed tarsi. Brachypsectrn placed here by
Dr. Leconte seems a veritable Dascyllide.

After a careful study of the characters of the family I can find
nothing which will warrant us in retaining it apart from the Dascyllidae.
The presence of an onychium seems to be the only character at present
relied on and this is present in Stenocolus (Lichas Ww..), a genus which
one would not desire to separate from association with Dasvi/Uus.

SANDALUS Knoch.
Four species are known to occur in our fauna which may be dis-
tinguished in the following manner :

Tarsi broad and flat, the joints deeply emarginate, the lamellae long and very-
distinct.
Thorax obtusely subangulate behind the middle. PI. II, figs. 12 — 13.

petrophyus Knoch.
Thorax regularly conical.

Thorax densely punctured and op.aque with numerous large punctures inter-
mixed porosus Lee.

Thorax finely punctulate and somewhat shining with very few coarser punc-
tures intermixed niger Knoch.

Tarsi rather slender, the joints feebly emarginate, the lamellfe small and in-
. conspicuous.
Thorax as in niger. PL II, figs. 10—11 califoriliciis Lee.

The sculpture of all the species is similar, the head densely and
coarsely punctured, thorax densely punctured with coarser punctures
intermixed, the latter less evident in niger. The elytra are densely
coarsely punctured, the punctures arranged in irregular rows, and on
the disc are often three faint costae.

In general form the last three species of the above table are quite
similar as shown on PI. II, figs. 10 — 11. S. petrophi/us however is
diiferent in outline as shown in figs. 12 — 13.

In color they vary in the species from castaneous to nearly black,
specimens occasionally occurring with the elytra testaceous. The an-
tennal flabellum of the male usually piceous is sometimes reddish.

JS. petrophyus Knoch, occurs from Pennsylvania to Illinois.

«S^. porosus Lee, Texas and New Mexico.

S. niger Knoch, Middle States to Texas.

*S'. (•alifornicus Lee, California and Nevada.

DASCYLLID^.
ACNEUS Horn.

This genus was founded by me on a 9 in my cabinet which suggested
a form distinct from any of the genera known. For its characters I
could only say that " the prosternum is depressed between the coxae, the
latter therefore more prominent than it."

The parts of the mouth are very similar to those of Ectopria, which
it otherwise resembles except in the characters of the male which are
as follows :

Male. — Antenna) with first joint stout, suddenly narrowed at base,

BRACHYPSECTRA Loc.

In a preceding page I have suggested the propriety of referring this
genus to the Dascyllidge. The entire absence of onychium excludes it
from Rhipiceridae, and while I have but little faith in the propriety of
retaining the latter family as distinct, taking the characters as we find
them the genus goes better with the Dascyllidae.

The anterior coxae are angulate externally and the trochantin quite
distinct. The ft-ont is however narrowed by the insertion of the antennaj
and the mouth is inferior as in Eubriini, two characters decidedly at
variance with the Dascyllini. I would therefore suggest a change of
the table proposed by me in a Revision of the Dascyllidae (Trans. Am.
Ent. Soc. 1880, p. 77), as follows:

Antennpe distant at ba.se, front not narrowed.

Epistoma prolonged, etc MAcnoroooNiNr.

Epistoma short, etc Dascyllini.

Antennas approximate at base, front narrowed.

Labrum visible, mandibles not prolonged, mouth inferior Brachypsectrini.

The tribe thus suggested indicates a line of affinity between the sub-
family Dascyllidae and the Eubriini, which is otherwise quite wanting
except through a series of other Helodide genera.

The specimens I have studied appear to be females only. The antennae
are formed in a manner leading us to expect the antenna of the S to
be pectinate. PI. II, fig. 15.

OO GEO. H. HORN, M. D. ^

While on the subject of the Dascyllidae it might be as well to call
attention to Psepheiius, a genus at present placed among the Parnidae.
It is provided with a very large troehantin to the anterior coxae, and
there is an entire absence of the prosternal lobe which is seen in all
the Parnidae protecting the mouth beneath. The abdomen is also
constructed on a plan entirely at variance with the latter family but
considerably resembling many of the smaller Dascyllidae. I do not
feel fully prepared to defend a union of Psephenus with the Dascyllidae,
but merely to call attention to the obvious disturbance of the otherwise
homogeneous structure of the Parnidae by retaining it there.

In a paper which I hope to present in the future this genus will be
more fully discussed and with it Lara also, which, though less irregular
in its characters, introduces an element in the Parnidae which does not
seem to fully belong there. Having but recently seen an absolutely
perfect specimen of this insect, the amount of study which I have been
able to devote to it is not sufficient to warrant a decided expression of
opinion either way.

AMERICAN COLEOPTERA. 91

On the genera of CARABIDvE with special reference to the
fauna of Boreal America.

BY GEORGE H. HORN, M. D.

Before entering the subject of the present essay it will be useful to
consider some preliminary matters about which there is still some dis-
cussion and differences of opinion.

The Carabidje forms one of the members of the Adephagous series of
coleoptera which is readily recognized by the predaceous character of its
mouth parts, its slender antennae (except in Gyrinidae), pentamerous tarsi
and the structure of the first abdominal segment which is in all cases
divided or hidden by the posterior coxae in such a manner, that it is
entirely lateral, rarely appearing as a small triangular piece between the
posterior coxae.

The ventral character is an important one and it prevails without
exception in the entire series. If we examine the Gyrinidae, however,
which the books all agree in saying have six ventral segments, the first
segment will be found apparently very long and passing entirely across
the abdomen without interruption by the coxae. A more careful ex-
amination will show that this segment is really composed of two closely
united, but with traces of the suture visible near the coxae as I have
illustrated on PI. Ill, fig. 9. The Gyrinidae therefore have seven ven-
tral segments.

With an apparent exception thus disposed of the limits of the ftimilies
of the Adephaga are to be considered and here is the point where the
greatest diversity of opinion prevails, especially with reference to the
Haliplidae and the two aberrant genera Amphizoa and Fe/obim.

The Haliplidje are placed by Lacordaire in the Dytiscidae rather under
protest, while subsequent authors have removed them in a more or less
decided manner either as a separate family or sub-family. In a pre-
liminary sketch of a new classification of Dytiscidae, ( Comptes-rendus
de la Soc. Ent. Belg. Sept. 4, 1880), Dr. Sharp says: "I exclude the
Haliplides from the family and leave for the Carabophiles to decide
whether they should be considered Carabidae or form a distinct family."
They should form a separate family ; my reasons will be given hereafter.
Amphizoa immediately concerns our fauna. It was originally de-
scribed as typical of a distinct family by Dr. LeConte, (Proc. Acad.
1853, p. 227 — 8), and notwithstanding the opposition of Schaum the

92 GEO. H. HORN, M. D.

same view is maintained in the Classification of the Coleoptera of North
America. Chaudoir (Bull. Mosc. 1872), says : " notwithstanding the
opposition of many entomologists, this genus can be placed only in the
vicinity of Trachypachya, as a distinct group."

Dr. Sharp in the paper above cited claims for Amphizoa a place in
the Dytiscidae in the series Dytisci comph'cati^ which have the meta-
sternal episternum taking part in the closure of the middle coxae. This
character which I first observed in Amphizoa and illustrated by a figure,
(Trans. Am. Ent. Soc. 1867, p. 157), appears to have caused Dr. Sharp
to arrive at the above conclusion. I believe Amphizon to be far less
a Dytiscide than a Carabide.

The series in which Dr. Sharp places Pelohius is called Dytixci frag-
mentati which is characterized by the less complex structure of the outer
side of the middle coxal cavities. Here the same number of pieces are
found which we observe in the sub-family Carabinag, that is, the meso-
sternum, its epimeron and the metasternum. These two series of Dytiscidae
Dr. Sharp very aptly compares with a similar division of the Carabidae
in two series, in which the D. fragmentati represent the more highly
specialized Carabinae and the D. compUcatl the Harpalinae. In Amphizoa
and Peiobius I see two distinct types each with a very evident Carabide
relationship and intermediate between the Carabinas and Dytiscidae in
two distinct lines. The Carabinas seem to be a centre from which the
other Carabidae and the Dytiscidae diverge, the former toward a simpler
the latter to a greater degree of complication of the coxal structure.

Peiobius was accepted by Lacordaire and many since as an undoubted
Dytiscide with certain aberrant characters. Dr. Sharp, while admitting
that it has but little claim to such a position, places it at the head of
that family notwithstanding that he says, "the Carabide predominates
over the Dytiscide in its organization." That he acts thus with impartial
fairness to two very aberrant genera, must be admitted, but I hope to
show that in all the Adephaga there exist characters of very great
systematic importance which have been entirely overlooked and which
will define with great accuracy the relationship of the various families.

It must be evident to all that there are radical diiferences in the
formation of the under side of the body in the now recognized families
of the Adephagous series. Many of the characters making up these
difi"erences have been made use of by various authors and they have
now become the common property of the science.

The structure of the metasternum demands a new study and here will
bo found the important characters to which I have already referred.

AMERICAN COLEOPTERA. 93

If we examine that portion of the body of a Cicindelide, Carabide or
HaUpHde, it will be observed that the metasternum consists of two
distinct pieces, the anterior or that which makes up the greater part of
that member and .the posterior or ante-coxal piece separated from the
former by a well marked suture extending entirely across the body.
This line of separation has probably been considered merely a matter of
sculpture but in some Carabidae, especially the 0 z ae n i n i, the two
sternal pieces may be entirely separated by a short immersion in a solu-
tion of caustic potassa. In fact in these last named insects I am inclined
to believe the suture somewhat mobile, as there is an evident laxity
of articulation in the side pieces of the body as well as between the
meso- and metasternum. The suture and piece intended will be seen
on PI. Ill, figs. 1—5.

In Amphizoa and Pelobius the structure is entirely different. There
is but a very small ante-coxal piece with the suture in front of it very
indistinct and the posterior side truncate and not prolonged between
the coxae as will be observed in the preceding families. This gives the
metasternum the appearance of being truncate behind, a form of ex-
pression already made use of by various authors. This structure is
shown on PI. Ill, figs. 6 — 7.

In the Dytiscidae and Gyrinidae with their short metasternum there
will be observed an entire want of any such structure. The ante-coxal
piece is entirely absent without trace of suture, and the metasternum is
pointed between the coxae. The under sides of Di/tiscus and Dineutvs
are represented on PI. Ill, figs. 8 — 9.

The posterior cox?e also diifer greatly in the various families. In all
the coxae are contiguous except in a comparatively few Carabidac, the
extent of the contact varying greatly from a mere angular touching to
quite a long edge of contact. In the figure of Cychrus (PI. Ill, fig. 1),
the coxfe will be seen separated by a small triangle of the first ventral
segment, Pterostichus (fig. 2), and Morm.nI//ce (fig. 3), show a mere
point of contact, while in the other genera on the plate the extent
01 contiguous edge varies, being greatest in Diveutus.

The coxae reach the side margin of the body, separating the meta-
sternal side pieces from the first ventral segment, in all the families
excepting the Carabidae and Cicindelidae. Track// park// a of the former
fiimily makes an exception. With this extent of the coxae externally
we have associated an immobility of the coxae, thus aff'ording a firm
point of support for the hind legs required by the mode of life of all
the genera possessing it. The extent of median contiguity tends to

(19)

94: GEO. H. HORN, M. D.

give still greater firmness. Trachypachys has the coxae as mobile as in
ordinary Carabidae, there is however but a short line of median contact.

With the above notes and the characters already well known in the
books an arrangement of the Adephagous families may be outlined in
the following manner :

Metasternum with an ante-coxal piece, separated by a well marked
suture, reaching from one side to the other and extending
in a triangular process between the coxae.
Antennae eleven-jointed. Posterior coxae mobile and simple. Habits
terrestrial.
Antennae inserted on the front above the base of the mandibles.

CICINDELIDiE.
Antennae arising at the side of the head between the base of the

mandibles and the eyes CARABID.^.

Antennaj ten-jointed. Posterior coxae fixed and with large plates
almost entirely concealing the abdomen. Habits aquatic.

HALIPLID^.
Metasternum with a very short ante-coxal piece, the suture indistinct,
posteriorly not prolonged between the coxae. Habits aquatic.
Legs ambulatorial. Anterior coxae globular.

AMPHIZOIDiE.

Legs natatorial. Anterior coxag conical. . PELOBIID.^.

Metasternum prolonged behind in a triangular process, the ante-coxal

piece entirely wanting. Habits aquatic.

xlntennae slender, filiform or setaceous. Abdomen with six segments.

Eyes two. DYTISCIDiE.

Antennse irregular, very short. Abdomen with seven segments, the
first two closely united. Eyes four. . . GYRINID>ffi.

The above scheme seems to give a division of families in accord with
both structure and habits. I have used the expression "aquatic" in
order that Amphizoa might be accommodated, its habits, while sub-
a(iuatic, are by no means " natatorial." I have already given a sufii-
ciently full account of the habits of this remarkable insect, (Proc. Ent.
Soc. Phil, vi, p. 289), and will merely add in brief that it acts precisely
like the Parnida? and is equally poor as a swimmer, and a very awkward
walker out of the water.

The Cicindelidaj, with the exception of a few genera, have the maxillae
armed at tip with a movable hook. This is peculiar to the family. For
many years the books have presented Trignnodacfyla of the Carabidae
as an exception and an articulated hook assigned to it. In the discussion

AMERICAN COLEOPTERA. 95

of the Ctenodactylini tliis will be shown not to be true, as illustrated
by fig. 70. I have observed among the M antic or ini, as represented
by Amhlychila, Omus and Manticora, that the posterior coxse are sepa-
rated, the intercoxal process meeting the metasternum by an obtuse
articulation. The other tribes have these coxae contiguous.

In a review of the opinions expressed by authors regarding other possi-
ble members of the Adephagous series we find the Paussidae included by
Burmeister (Mag. Zool. 1841, Ins. pi. 76), and the Rhysodidae by Crotch
(Proc. Amer. Philos. Soc. 1873). These must be excluded for many
reasons, more especially as they fail to present the ventral structure which
may be safely taken as the key. If we admit them there is no reason why
some and after them all the Colydiid^e should not be admitted and the
door would be open to much of the Clavicorn series. It must be admitted
however that Faunsus is the nearest approach of the Clavicorn series to
the Adephaga the approximation in another direction being through the
■ Byrrhida? and Parnidfe with however a very wide interval.

Having established limits for the series as well as for the family
Carabidae, it will probably produce a better understanding of the subse-
quent pages if the various parts of the body are reviewed and their
modifications studied, so that a correct idea may be obtained of the
value to be assigned to each change of structure.

CARABIDAE.

Head. — The head is usually oval, rarely very broad (Pasimackm,
Enceladtis, Siagona) or very elongate. In the latter case the elongation
may be in front of the eyes as in Ci/thrus or behind them as in Camonia
and Morrnolyce. The neck is often suddenly constricted and sometimes
behind the constriction expandecl to a semiglobular condyle which admits
of very free motion of the head in every direction. The clypeus is usually
narrower than the front and more or less prolonged but in the L i c i n i n i
is not more prominent than the sides of the front. In DlcrocMle and
Zargus the central portion is membranous recalling the structure of that
of Necrophorus.

The head is provided with sette which seem to be special tactile organs
and which from their constancy, as well in position as presence, have an
important bearing from a systematic point of view. The supra-orliital
setae may be either two or one in number or even entirely wanting as in
the Pseudomorphinas. When there are two setfe the anterior is situated
close to the border of the eye always in front of the middle, the posterior
is at a distance within the eye opposite the posterior margin. If one seta

90 GEO. H. HORN, M. D.

is present it may be close to the eye, usually it is a little removed, it is
never in front of the middle.

The clypeus also bears setae, usually one on each side and as a general
rule those genera with two supra-orbital setae have the clypeal seta situ-
ated at the middle of the side of the clypeus at a slight distance from the
margin, while those with one supra-orbital have the clypeal near the an-
terior angle. Rarely there are more than one clypeal setae at the side, as
in certain Anisodactylus while in Pelecium {ci/anipes) there is no seta
whatever it being apparently replaced by a considerable development of
the outer seta of the labrum.

Eyes. — These organs are sometimes entirely absent, the instances are
now rather numerous and well known. When present the form shows
but little variation from the round or oval form (see Ozsenini). Their
size however varies greatly and with it the prominence, Siagona having
very small eyes and in Elaphrm they are large and prominent. When
the eyes are large relatively to the size of the head, whether unduly
prominent or i^t, they approach very closely beneath the head to the
edge of the buccal fissure, when small they are distant from the mouth.
This seems to be very useful systematically but has not been made use
of before the present paper. The granulation also varies but I have not
been able to make use of this.

Antenna. — These are always eleven-jointed, usually filiform or seta-
ceous, sometimes moniliform or compressed. The form seems to have less
value from a systematic point of view than the extent of fine pubescence
covering the surface of the joints. The antennae have three kinds of
pilosity, sometimes all present at the same time. First, a dense, fine,
short, recumbent pubescence which is present on those joints with a fine,
dense punctuation indicating probably the presence of a special sense
identical with or resembling the sense of smell in animals of a higher
organization. Second, a longer hairyness diiFusely scattered over the joints,
and finally stifFer hairs around the distal ends of the joints, these are
especially well marked in Loricera and allied genera. The basal joint is
not at any time very long but in the Scarites and Dryptini sufiiciently
elongate to attract notice, on the anterior face of this joint near the tip is
a long seta. The extent to which the pubescence covers the antennae
has been used by many systematists since Lacordaire but there are so
many striking exceptions within tribal limits that it can only be used for
separating tribes and never for defining any higher groups. The surface
of the antennae is not always uniformly punctured. In those genera with
the ant(!nnae at all flattened, one or both sides have a median smooth

AMERICAN COLEOPTERA. 97

space. This is well marked in the Helluonini, Pterostichna and
many Harpalini. The number of basal joints which may be glabrous
varies from two to four, but in Trachyj)achys there is no pubescence
whatever.

It is extremely rare that the antennae are received in well marked
grooves on the under side of the head. The Pseudomorphinfe are
I believe the only instance of this.

Labrum. — This member varies greatly in form and size. It is usually
transverse truncate in front or slightly emarginate, ciliate or with four or
six setae along the margin. It is rarely bilobed ( Ci/chrua, Dicrochile,
Zargus}, sometimes very large and convex {Anthid) or prolonged cover-
ing in great part the mandibles {FiricaluK, etc.). In some genera the
marginal setae may be very small, Anthia or entirely wanting, Macrn-
chilus and other genera of Helluonini.

Mandibles. — These are variable in form and prominence, within
toothed, serrulate or simple. The tip is usually acute, the left mandible
overlapping the right. Sometimes however (certain Harpalini) the
mandibles meet in a pincer-like manner. The outer side is usually con-
cave, forming an elongate groove (called the scrobe), in which usually
beyond the middle is found a puncture bearing a moderate seta in
those genera of riparial habits {Nehria, Bembkh'inn, Fafrobuf, JVomius).
The presence of this seta is extremely important in defining the relation-
ship of genera otherwise obscure like Melsenns and Cose in ia. The scrobe
is, however, sometimes absent as in the genera allied to Feutagonka.

Maxill.e. — In the present family the inner and outer lobes are
always present as will be observed in the figures ( it will be seen that the
outer lobe is absent in Dineutus, 151). The inner lobe varies somewhat
in form, it is usually hooked at. tip, the hook nevei' articulated. The tip
may however be obtuse without hook as observed ifi Scaritini (19, 21,
22), Promecognathini (18), Pterostichini (45), Cratocerini
(107), Orthogonini {Anoncopeucus), Peleciini (111), or more or
less acute, without hook as in Glyplus (133). The inner edge is ciliate
or spinulose and very rarely with anything approaching a tooth. The
outer or palpiform lobe is biarticulate (except in CoUistus 118, and
Amerizus 38), the joints of variable relative length, the two together
at least equal to the inner lobe, with the single exception of G/yptus 133,
where they are shorter.

Of the maxillary palpi very little can be said in a general way.
The accompanying sketches represent every known variety of form.

The maxillary lobes by their differences above mentioned afford merely

98 GEO. H. HORN, M. D.

generic characters, while the form of the last joint of the palpus is used
to separate tribes, but it is not a very safe character.

Mentu^ni. — The mentum closes the mouth more or less perfectly
beneath usually allowing the outer side of the maxillae at base to be seen.
It is supported on a peduncle of the submentum the suture separating
them usually very distinct, rarely entirely absent as in Enceladus 26,
Siagona 31, Lesitignathus 65, certain Trechi 40, 41, and the Pseudo-
morphinae 147. The form of the mentum varies but no character of
systematic value has been obtained from this excepting in the Scarites
where it is very broad, or Drypta 76, from its nearly orbicular form.

The epilobes of the mentum are always present in the Carabidae
although much inflexed when the ligula is large as in Pasimachus 19.
They vary greatly in size from a narrow border, as is the usual occur-
rence, to a very wide piece as in Schizogenius 23. Their extremities are
often prolonged in an angle or even an acute process as in Anophthalrmis
40, or Ferigona 63. The epilobes have been made use of by Chaudoir
in the Lebiini {q. v.) and Pogonini, in the former case erroneously
in the latter with very little success.

The mentum is usually emarginate, sometimes very feebly or even
Brachylobus 117, truncate. At the bottom of the emargination in very
many genera a tooth of variable size and form occurs. The tooth is formed
in two ways. It may be made entirely of a prolongation of the middle
portion of the epilobes, or it may consist of a process of the body of the
mentum narrowly bordered by the epilobes. This character as well as the
form of the tooth will be found sufficiently represented in the sketches.

As a general rule when the mentum tooth is well developed the
'■ post-dental" aetse are very small, often inconspicuous, when the mentum
is dee]>ly emarginate and the central portion of the epilobes membranous
these seta3 are unusually large and conspicuous, they are also well de-
veloped where the ligula is unduly exposed as in Migadops 16. I have
but rarely represented these in the figures for fear of confusing more
important parts of the mouth.

In the emargination of the mentum we usually find a connecting
membrane which is the basal support of the ligula, and which varies in
extent in accordance with the degree of extensibility of the ligula."

Ligula or Labium. — It seems to me better that the latter name
should be adopted for the entire organ as most authors in speaking of
ligula may mean either the whole or merely the central member.

The labium consists of three parts, the central, usually corneovis, piece
on each side of which are membranous appendages called paraglossfe.

AMERICAN COLEOPTERA. 99

In every dissection I have made the three parts have always been
present, sometimes however very closely united and corneous - as in
Helluomorpha 103. It seems unprofitable to discuss the modifications
of the ligula and paraglossae, their forms are shown in the figures and
the explanations given in the tribal headings.

From my own observations I think the labium the most unsafe and
unsatisfactory organ that can be made use of in classification and the
poor results to be obtained from it need no further illustration than
Lacordaire's system of Carabidae. When the labium is used in the
division of tribes into smaller gToups and genera we have a microscopic
subdivision resulting which overwhelms the science in a chaos of inde-
finable groups and an infinity of genera which threatens the exhaustion
of the capacity of the classic languages for further combination.

A great part of the trouble with this organ seems to have resulted
from causes which Jacquelin Duval so well describes, (Gen. Col. Eur. i,
p. 34, note). When observed under varying external conditions the
paraglossae present rather diverse forms. They are often thin and
membranous and will contract and expand with moisture and fail to
present the same appearance when dry as when wet. My own dissections
have been drawn while the specimens were moist, and in the smaller
ones, enclosed in a drop of water.

The appendages of the ligula, the terminal setfie of varying number,
seem useful in assisting the placing of genera when properly subordinated
to other characters, but I think that genera based solely on the number
of these setae or their position must ultimately fail of recognition.

While I do not believe the ligula to possess the value assigned by
some authors it may be made useful. In some vast groujis like the
Pterostichini and Platynini there is a similarity of type which
one will readily recognize. There are however important modifications
that need riot mislead if properly studied, Leati'gnafhus 65, is one of
these. In this the ligula and paraglossae are both well marked, the
former feebly corneous, the latter slender and long but connected with
the central ligula by a transparent membrane which serves to add strength
to the organ which is at best very weak and thin.

Labial Palpi. — These organs are usually similar in their terminal
joint to the maxillary palpi, when they differ it affords a very useful
means of separating genera. It appears however to have escaped notice
that the relative length of the last two joints to each other is a matter
of fir greater importance than has been recognized. The terminal joint
may be e([ua\ to or longer than the preceding, or shorter. In the former

100 GEO. H. HORN, M. D.

case the penultimate joint is bisetose in front and in the latter plurisetose.
In the genera allied to' Oodes 119, 120, 121, I have not found any
setae except in EvoJenes 122, nor in Ch/senius pensylvanicus 115, and
Glyptus 133.

The entire groups Dryptini, Grraphipterini, Anthiini,
Zabrini and nearly all the Harpalini have the penultimate joint
plurisetose. The same character also occurs exceptionally in other tribes.
The character seems to be an important one and has been useful in
several of the tables.

Prothorax. — The form of the thorax plays but a subordinate part.
The obliteration of the lateral margin in Apotomus seemed to Schaum
to be very important but the same occurs in several remote genera, as
Agra and Camonia. The basal lobe by its presence has been useful
in the L e b i i n i. The special setae of the side margin are nearly as
important as those of the head. In those genera with two supra-orbitals
we can safely expect two at the side of the thorax one being in the hind
angle, where there is one supra-orbital that of the hind angle is wanting
except in Bradt/ceUiDi and some few allied genera. All the Oodini,
Anthiini, Grraphipterini, Cratocerini, Orthogonini
and GIt/ptus have no lateral setae that I can discover nor trace of
punctures from which they arise.

ScuTELLUM. — This is never large, sometimes entirely concealed
( Omophron), and in the pedunculate genera confined to the peduncle.
Its form is usually triangular.

Elytra. — These organs by their form play an important part in the
Harpalinje, in accordance with the form of the apex whether entire, sinu-
ate or trujicate, also the structure of the base whether margined or not.
The internal phca, which will be more fully explained further on, has
been recognized by Bedel in his tables, but its full import does not seem
to have been recognized. Its use seems to be, to hold the elytra more
firmly together by an interlocking with the margin of the abdomen.

The elytral sculpture is of course very variable, the normal form is
nine-striate but the stride in Cychrus far exceed this number. Some-
times the eighth and ninth striae are confluent or nearly so as in Oodes.
The eighth on its outer side bears ocellate punctures which in very
recent specimens bear long setae as shown in Fsydrus, (PI. lY, fig. 1).
The ocellate punctures are wanting in our Panagaeini, in Apotomus
and many Carabinfe.

Prosternum. — The modifications of this portion have proven
especially useful in the Carabinae as will be seen by reference to

AMERICAN COLEOPTERA. 101

the table. In the Harpalinse it is of less importance generically. In
Cydosomns the tip is much prolonged and acute.

Anterior CoxiE. — The cavities receiving these are always closed
except in a small number of tribes of Carabinae. In many cases the
positive determination of open or closed cavities can only be made by
separating the prothorax.

Mesosternum. — The mesosternum separates the middle coxae nar-
rowly, not often widely {Slagona and some Carabinje), rarely the coxal
cavities are confluent (certain 0 z a; n i n i). In front it is usually oblique
or nearly flat, rarely protuberant and carinate (some Carabinae). The
side pieces, epimera and episterna, by their form and extent give to the
division of the entire family one of its most important characters. In
the first sub-family Carabinae the epimera nearly equal the episterna
in size and reach the coxal caAaty. In the other two sub-families the
epunera vary in width but do not reach the coxae, and in some tribes
are extremely narrow, in fact linear or even partly hidden externally
by the episterna.

Mormolyve is one of the most remarkable exceptions in the entire
family. It is plainly by its structure otherwise, allied to the Truncati-
penne series but the mesosternal epimera reach the coxae ; nor does the
exception end here, the metasternal episterna also form part of the outer
side of the coxal cavity, a character otherwise unknown in the Adephaga
outside of the Dytisci complicati (PI. Ill, fig. 3). This gives an answer
to the closing lines of Dr. Sharp's paper. (Comptes rendus Ent. Soc.
Belg. Sept. 1880).

Metasternum. — This segment yields nothing of importance in the
classification of the family, its structure has given us the means of
dividing the Adephaga in a satisfactory manner. The side pieces are of
less importance than those of the preceding segment, the fusion of the
two pieces in one has been made use of but its importance exaggerated.
I have seen in the same species the epimera free or united with the
episterna without suture {Mefrius).

Posterior Cox^. — While it has been observed that the middle
coxae are sometimes contiguous, it seems to have escaped notice that
the posterior are equally variable. In the vast majority of genera the
coxae are contiguous although at times the contact is small and produced
by a slight extension inward of a small process of the coxae as shown in
PI. Ill, fig. 2. The metasternum and abdomen are however completely
separated, as efiectually as in those genera in which the contact is
' larger. This is the form observed in Pterostichini, Lebiini and

(21)

102 GEO. H. HORN, M. D.

H a r p a 1 i n i. In a comparatively few genera the coxae are plainly
separated and the small triangle of the first ventral segment becomes
visible between them. This character is scattered in all parts of the
series. In Brachymis it seems to lose its value as species occur with
the coxse contiguous or separated. In Trachypnchys alone the coxae
externally reach the side margin of the body. This character is usual
in all the following families but unique here.

Abdomen. — There are always six segments, the first lateral. Their
length varies but not to an extent to afi"ord systematic characters.
In Brachynus there are said to be seven or eight segments but this
is sufficiently discussed in that tribe.

Each of the first five segments bears near its posterior edge and on
each side of the middle a puncture bearing an " ambulatorial seta."
The last ventral is apt to vary sexually in its punctuation and the males
will be seen to have but one puncture each side and the females two.
Other sexual modifications of the last ventral are often observed, but
these have more often a specific than generic value.

Legs. — The only specially important variation is found in the anterior
tibiae whether emarginate or not on the inner side and with this the
position of the terminal spurs. In some genera the anterior tibi« are
grooved on the inner side in the axis of the member, these have the
spurs of necessity terminal. It will be observed then that the greater
the obliquity of the groove the more one spur is elevated so that when
the emargination is most perfectly developed the inner spur is at the
upper angle of the emargination. The tibial spurs are always present,
sometimes very short {Agra), or very long {Tetragonoderus), and in the
latter genus finely serrulate. There are two spurs, never more, notwith-
standing the assertion to the contrary in Zahnis.

Tarsi. — The feet are five-jointed without exception, the joints varying
among themselves in form and size, and many times afford a useful resort
for separating genera. The vestiture of the under side is variable generi-
cally and again sexually. The mode of dilatation of the anterior male
tarsi and the vestiture of the dilated joints whether squamulose, papillose,
pubescent, spongy or spinous, gives at times the only constant character
for the separation of groups of genera.

As a rule the anterior tarsi of the male are dilated in from two to four
joints while it often happens that the sexes can not thus be separated.

Ungues. — The claws are more often simple than otherwise but
numerous instances occur in which they are dentate, serrate or pectinate.
These variations are useful for the separation of genera.

AMERICAN COLEOPTERA. 103

Facies. — Species of a genus and genera of a tribe have a greater
or less resemblance which affords to the practiced eye an easy guide to
position, but there are in many parts of the series such close repetitions
of form that this can not be relied on. Tetragonoderus and Bembi'dmm,
Patrohus and Nebria, Di/schirius and Apotomus, Cyclosomus and
Omophron, are instances of this mimicry. On the other hand allied
genera will be found presenting diversity of aspect and some may be
polymorphic as to their species, as Carabus and Ct/chrus.

With this review of the separate parts of the body the preliminary
portion of this essay closes. I have purposely avoided citing many
instances of the occurrence of each character as the genera are unknown
to most of the students of our fauna and our native genera have been
cited when they answer the purpose.

The Carabidie may be divided in the following manner into three
sub-families :

Middle coxal cavities not entirely enclosed by the sterna, the epimcron

of the mesosternum attaining the coxa. . . . CARABINE.

Middle coxal cavities entirely enclosed by the sterna, the epimeron not

attaining, the coxa.

Head without antennal grooves beneath and with distinct supra-orbital

setae. Ambulatorial setae of abdomen usually well developed.

HAR PALING.

Head with distinct usually long antennal grooves beneath and without

distinct supra-orbital setae. Ambulatorial setae of abdomen feeble

or wanting PSEUDOMORPHINJS.

The only exceptions known' to me in the structure of the middle coxal
cavities is in MormoJjjve^ of which mention has already been made. The
0 z a3 n i n i and S i a g o n i n i have been considered exceptions but by care-
ful preparation of specimens I have found the coxal cavities as in the Harpa-
linae. In the proper place these matters will be found more fully discussed.

Sub-Family CARABINjE.
. Middle coxal cavities partially closed by the sterna the intervening space
occupied by the mesosternal epimeron. Head with one or two supra-
orbital setigerous punctures. Sides of thorax usually with two setigerous
punctures. Anterior tibiae either entire, obliquely grooved or emarginate,
the spurs either both apical or with the inner more or less remote.

The tribes of this sub-family contain a less number of genera than the
Harpalinae, but of such a specialized type as to make it necessary to separate
them to such an extent that many of the tribes contain but one genus.

104 GEO. H. HORN, M, D.

The following table gives in brief the characters which separate
the tribes :

Posterior coxse attaining the side margin of body. Anterior coxal cavities open be-
hind. Mandibles with setigerous puncture Tribe II. TrachypacMni.

ate Tribe V. Pamborini.

Anterior tibise obliquely grooved within, the spurs terminal and nearly
on the same plane. Mentum closely connate with the submentum.

Tribe XIV. Enceladini.
Posterior coxse contiguous.

Anterior tibise emarginate within, the outer apical angle prolonged.

Tribe XV. Scaritini.

Of the above tribes ten are represented within our faunal limits and
but one of these, Metriini, is peculiar to it a.s far as the genera of the
sub-family are known to me.

It is impossible to give these tribes a linear arrangement without

AMERICAN COLEOPTERA. 105

violating some of the affinities but the numerical sequence above seems
to be the least objectionable.

Representatives of all have been studied from nature except Hiletini,
so rare seem the species that with all my exertion I have been unable to
procure one of them.

I can hardly allow the present occasion to pass without expressing my
great sense of obligation to Messrs. Bates and the Jansons of London,
Salle of Paris, and Dr. Dohrn of Stettin, for their ready response to my
calls for rare and valuable material.

Tribe I. — Omophroniiii.

Antennse slender, inserted under a slight frontal margin, four basal joints
glabrous. Eyes round, moderately prominent, distant beneath from the buccal
opening. Head deeply inserted, with one supra-orbital seta. Labrum short,
emarginate. Mandibles not prominent, arcuate, acute at tip, simple within or
slightly toothed near the base, outer side slightly concave with a setigerous
puncture. Maxillfe slender, inner lobe hooked at tip, spinulose within, outer
lobe slender biarticulate, palpi slender the last two joints equal. Mentum deeply
emarginate and with an acute tooth, ligula truncate and slightly broader at tip
and bisetose, the paraglossse free at tip but not longer, the palpi slender, second
joint longer than the terminal and plurisetose in front. Thorax applied directly
against the base of the elytra, sides with a single setigerous puncture a little
behind the middle. Scutellum invisible. Elytra convex, margined at base, sides
narrowly infiexed margin continuous. Prosternum rather widely separating the
coxpe, prolonged and dilated behind them and completely covering the meso-
sternum the coxal cavities closed behind. Mesosternum in front vertical and
carinate with two fossje to receive the under side of the anterior eoxse. Meta-
sternum short, epimera not distinct, posterior coxte contiguous. Tibipe finely
spinulose externally, the anterior slightly broader to tip, within obliquely grooved,
the inner spur above the apex. Tarsi slender.

The males have one or two joints of the anterior tarsi dihited and spongy
pubescent beneath.

One genus constitutes this tribe, Omophron, concerning which all
authors seem to be in accord in permitting it to remain alone.

At first glance the posterior coxae seem to be separated, but a little
care will readily detect the small laminiform processes which by their
meeting conceal the small remnant of the first A^entral segment.

European authors describe the ligula and paraglossse somewhat different-
ly but the figure given is that which will be found in 0. dentatum Lee.

The plurisetose second joint of the labial palpi is a character of
extremely rare occurrence in the present sub-family, it is the usual
structure in Cicindelidse and very constant in Dryptini' and ITar|)alini
of the sub-family Harpalinac.

The affinities of the present tribe are very difficult to define. It
seems out of place in any part of the series. Specialization of type

TRANS. AJI. ENT. SOC. IX. (22) Air.M-ST. 1 SSI

106 GEO. H. HORN, M. D.

seems to be carried to such an extreme in the present sub-family that
tribes may be separated containing one or at most two genera, except in
the Scaritini and possibly the Migadopidae as defined by Chaudoir.

Tribe II.— Trachypachini.

Antennae moderate, arising under a distinct frontal margin, the joints all
glabrous with a few hairs near the tip of each, first joint stout but short, third
very little longer than the second. Eyes oval, not prominent, moderately distant
from the buccal fissure. Head deeply inserted in the thorax, with two supra-
orbital setse. Labrum short, broadly but feebly emarginate. Mandibles stout,
arcuate, concave on the outer side and with a setigerous puncture. Maxillse with
inner lobe stout, falciform, ciliate and spinous within, outer lobe rather stout,
with two equal joints, palpi stout, the second and fourth joints equal, the third
a little shorter. Mentum short, broad, with distinct suture at base, anteriorly
feebly emarginate with an emarginate tooth. Ligula broad, rounded and bisetose
at tip, the paraglossse membranous, obtuse at tip, slightly longer than the ligula,
the palpi short, the second joint with one seta, in front, the third elongate-oval.
, Thorax with three setigerous punctures at the sides, the first at apical angle, the
second at middle, the third at basal angle. Body not pedunculate, scutellum
distinct. Elytra not margined at base, sides narrowly inflexed, margin not in-
terrupted. Prosternum horizontal at tip prolonged behind the coxae, the eoxal
cavities open behind, prosternal sutures indistinct. Mesosternum oblique and with
a carina in front between two fossse which receive the anterior coxae. Metasternal
epimera invisible, the posterior coxae contiguous within and reaching the side of
the body separating the metasternal side pieces and the abdomen. Legs not long,
femora stout, middle and posterior tibiae spinous externally, anterior tibiae spinous
posteriorly, gradually stouter to tip, sulcate and feebly emarginate, the inner spur
above the tip.

The anterior tarsi of the male have two joints feeblj' dilated and spongy
pubescent beneath.

This tribe contains two genera Trachypachys and Syslolosoma, the
former occurring in our fauna and Europe, the latter in Chili.

The characters above given show such an apportionment of those
peculiar to the sub-family, with the addition of one not found in any of
the tribes of Carabidas, that it is difficult to say in which direction the
affinities are most marked, but those toward the Nebriini and Elaphrini
seem to be the most evident. As in all the other tribes of the present
sub-family the affinities seem to be complex, and will appear stronger or
weaker in accordance with the standpoint from which we view them.

The form of the posterior coxae is the character more especially note-
worthy in this tribe. These members are not of unusual dimensions but
extend to the margin of the body, their line of contact with each other
is also greater than is usual in the entire family.

In the Berlin Zeitschr, 1860, p. 166, Schaum states that Trachypachys
has three spurs to the anterior tibiae, two terminal and one above the
emargination, and on p. 167 the same is said of Metrius. From my

AMERICAN COLEOPTERA. 107

own observation no coleopterous insect ever has more than two spurs
to each tibia except by monstrosity, consequently the above statements
are incorrect.

Tribe III.— Cychrini.
Antennse slender, setaceous, four basal joints glabrous (two only in Nomarehin) ,
inserted under a feeble frontal ridge ; first joint long and often stout, third longer
than second. Eyes round moderately prominent, distant beneath from the buccal
opening. Head more or less constricted, with one setigerous puncture above the
eye, neck often semiglobose. Labrum deeply bifurcate. Mandibles long and
prominent, arcuate and acute at tip, and at least bidentate within, and with no
setigerous puncture externally. Ligula acute and bisetose at tip, the paraglossse
variable. Labial palpi long, the second joint elongate, plurisetose in front, last
joint securiform and concave. Maxillae with inner lobe slender, hooked at tip,
ciliate or spinous within, the outer lobe stout with the terminal joint longer, the
palpi long and slender, the last joint seeuriform and concave. Mentum deeply
emarginate without tooth. Thorax variable in form with a lateral and antebasal
setigerous puncture. Body not pedunculate, scutellum scarcely evident. Elytra
not margined at base, sides rather widely inflexed, margin acute and not inter-
rupted. Prosternum usually not prolonged behind the coxse the tip obtuse, the
coxal cavities open behind. Mesosternum nearly vertical and obtusely carinate
in front. Metasternal epimera not' distinct. Posterior coxae separated by a tri-
angular process of the abdomen. Legs long usually slender, the femora usually
very feebly clavate. Anterior tibiae very slightly broader to apex, grpoved within
near the apex, the spurs terminal but placed slightly obliquely to each other.
Tarsi slender, the first joint long, the fourth entire.

Anterior tarsi usually dilated in the males with a variable number of joints
spongy pubescent beneath.

As above defined the present tribe contains those genera included by
Lacordaire excepting Dumaster which Chaudoir has properly removed
to the Carabini. Probably misled by the presence of Damaster, Schaum
has suggested the union of the present tribe with the Carabini, but the
characters separating the two are so well marked and sharply defined that
they must be retained as distinct.

The separation of the posterior coxae which seems to have escaped
notice here as well as in several of the following tribes is a character
of too great importance to neglect. It is repeated in Metritis^ Prome-
cognathus and Enceladus, but there exists too wide an interval between
the Cychrini and these genera for us to suggest any special affinity with
either of them. With the Carabini the Cychrini appear to have the
closest relationship.

Two genera form this tribe, both represented in the United States.

Antennae with four basal joints glabrous C'yclirus.

Antennae with two basal joints glabrous Noiiiarotiis.

Cychrus as above defined is rather polymorphic and is capable of

division into parts which rank rather as sub-genera than genera. Those

108 GEO. H. HORN, M. D.

occurring in our fauna have been the subject of a study by me in which
these divisions have been treated in sufficient detail (Trans. Am. Ent.
Soc. 1878, pp. 168—185).

Two important divisions may however be noticed, those in which the
anterior tarsi are similar in the sexes and slender, and those with the
anterior tarsi dilated in the males. To the first of these series belong
the European species and three in our own fauna which occur west
of the Rocky Mountains. Those with dilated tarsi are peculiar to our
fauna. These two series seem to bear the same relationship to each other
that Damaster does to Carabus.

In Nomaretus and one group of Cychrus (Sphseroderus), the tip of
the prosternum is somewhat prolonged and Chaudoir holds the opinion
that, from this fact and the more widely dilated tarsi of the male, the
group should have generic value. I do not see any necessity for this,
for if we attempt to divide Ci/chrus more than two divisions will be
required and the subject unnecessarily complicated.

Tribe IV.— Carabini.

Antennre slender, with four basal joints glabrous, arising under a feeble frontal
ridge. Eyes round moderately prominent and distant beneath from the buccal
opening. Head not constricted behind the eyes and with one supra-orbital setiger-
ous puncture. Labruiii broad and emarginate. Mandibles stout, arcuate, acute
at tip, concave on the outer side and without setigerous puncture. Mentum broad,
emarginate, with a variable tooth. Ligula variable, the paraglossse distinct.
Maxillse with inner lobe strongly hooked, densely ciliate within, outer lobe
stout. Palpi moderate or long, .last joint of both pairs securiform. Thorax with
a setigerous puncture at the side and one also near the posterior angle. Body not
pedunculate, scutellum small. Elytra feebly embracing the sides of the body,
the lateral margin continuous. Prosternum horizontal at tip and prolonged, the
anterior coxal cavities open. Mesosternum nearly vertical and subcarinate in
front. Metasternal epimera invisible, posterior coxse contiguous. Anterior tibiae
gradually broader to tip, slightly grooved within, the spurs terminal but placed
obliquely to each other. Femora moderate, the anterior stouter. Middle and
posterior tarsi long and slender, the anterior shorter.

In the males the anterior tarsi are dilated and densely pubescent beneath, the
dilated joints variable in number, simple in both sexes in Damaster.

This tribe is composed of species of at least medium or even of large
size, remarkable for the most part for their beauty of form, color and
sculpture. As here defined it contains those genera not of the Nebriide
type with the addition of Damaster. This latter genus as remarked by
Schaum (Ann. Fr. 1862, p. 68), differs from Carabus merely in the
absence of dilated tarsi in the male. The entire structure is so closely
that of Carabus and so different from Cychrus that it seems almost
impossil)le that Lacordaire should have associated it with the latter genus.

AMERICAN COLEOPTERA. 109

I entirely agree with Chaudoir (Bull. Mosc. 1861, p. 502), in placing

Damaster in the present tribe.

Within our faunal limits but two genera occur separated by the form

of the third antennal joint.

Third joint of antennae cylindrical '. CarabilS.

Third joint of antennse compressed Calosoma.

In their numbers of species these genera in our fauna reverse that of
Europe where Carabua is far more numerous than Calosoma, with us
the latter genus has the greater number of species but the disparity
between the genera is not so great as in Europe.

Tribe V. — Pamborini.

Antennse straight, moderate in length, arising under a distinct frontal margin ;
first four joints glabrous, first joint slightly elongate, third longer than second.
Eyes not large, moderately prominent, distant from the buccal fissure. Head
narrowed behind the eyes to a distinct neck and with a single setigerous puncture
over each eye. Labrum transverse, deeply but broadly emarginate. Mandibles
arcuate, acute at tip, strongly dentate within, without setigerous puncture. Mentum
short, broad, narrowed in front, broadly but feebly emarginate, epilobes narrow
but distinct, mental suture distinct. (Ligula and maxillse not dissected.) Labial
palpi robust, the terminal joint longer, elongate securiform, second joint without
setse. Maxillary palpi similar but with the second joint longer than the fourth.
Thorax somewhat narrowed behind the hind angles slightly prolonged, a setigerous
puncture at middle of sides another near the hind angle. Body not pedunculate,
scutellum short and broad. Elytra not margined at base, lateral margin entire,
sides moderately inflexed. Prosternum horizontal and prolonged at tip, anterior
coxal cavities open behind. Mesosternum nearly vertical obtusely carinate in
front. Metasternal epimera indistinct, posterior coxEe contiguous. Femora moder-
ate, the anterior slightly stouter. Anterior tibise broader to tip, the outer apical
angle prolonged, deeply grooved on the inner side, the inner spur situated con-
siderably above the outer. Tarsi slender, the first joint equal to the next three
together, fourth joint slender.

Anterior tarsi slender and similar in both sexes.

This tribe contains but one genus peculiar to Australia, Pamborus.
Lacordaire has associated JVj^ns with it, but by what process of reason-
ing I have been unable to determine and which has been very properly
separated by Chaudoir and associated with Fanagseus. By the open
anterior coxal cavities, the form of the mesosternum and the contiguous
posterior coxae, Pamborus exhibits a decided relationship with the
Carabini, but the structure of the anterior tibiae and the more widely
inflexed elytra are abundantly sufficient to separate it as a distinct tribe.
By the latter character a relationship is exhibited with the Cychrini and
by the anterior tibiae with Scaritini. It might also be observed that the
structure of the head above resembles Peleciuvi but beyond the resem-
blance there is no further affinity.

Tribe VI.— Hiletini.

Antennae moderate in length, inserted under a well marked frontal plate,
geniculate, the first joint elongate, received in repose in a depression beneath the
eyes. Head oval, stout, with two supra-orbital setae. Eyes small not prominent.
Labrum transverse feebly emarginate. Mandibles broad, arcuate externally and
curved from above downwards and without seta on the outer side, pluridentate
within. Maxillary palpi securiform % or triangular 9- Mentum broad, deeply
emarginate with a large quadrifid tooth. Ligula elongate, spatuliform, rounded
at tip, the paraglossse shorter, linear and ciliate, terminal joint of the palpus more
strongly securiform in the male. Thorax subcordiform. Elytra parallel feebly
convex. Presternum prolonged at tip and received in a depression of the meso-
sternum, anterior coxal cavities open behind. Metathoracic epimera distinct.
Legs moderate. Anterior tibiae entire, the spurs terminal. Tarsi short. Posterior
coxae not contiguous.

The first three joints of the anterior and middle tarsi of the male are feebly
dilated and spongy beneath.

The tribe contains but one genus Hiletun which is unknown to me in na-
ture, the above characters have been obtained from the books in great part,
to which I have added others kindly observed for me by Mr. H. W. Bates.
The relations of the tribe, like many others of the sub-family, are
complex, but on the whole it seems better placed near the Pamborini
and Carabini than elsewhere.

Tribe VII.— Elaphrini.

Antennae moderate in length, rarely longer than head and thorax, three basal
joints glabrous, the fourth pubescent at tip or entirely glabrous in Diachila, base
free, a slight ridge in Blethisa. Eyes round, usually prominent, moderately distant
from the buccal fissure. Front more or less deflexed, with two supra-orbital setae.
Labrum moderate, truncate. Mandibles stout, concave extei'nally, with a setiger-
ous puncture, arcuate, acute at tip. Maxillae hooked at tip, ciliate or spinulose
externally, outer lobe slender biarticulate, palpi moderate in length, terminal
joint longer than the preceding. Mentum emarginate with a bifid or emarginate
tooth, ligula free at tip, bisetose, acute in Elaphruf!, broad in the other genera,
paraglossffi slender longer than the ligula, the palpi moderate, the last two joints
equal the penultimate bisetose in front, except in Diachila. Thorax variable in
form, the seta in the posterior angle always present, the lateral absent in most
Elaphrus. Body not pedunculate, scutellum distinct. Elytra not margined at
base except feebly near the humeri in Blethisa, sides narrowly inflexed, margin
entire. Prosternum obtuse at tip not prolonged behind the coxae, the coxal cavities
closed. Mesosternum not prominent. Metasternal epimera not distinct, the pos-
terior coxae contiguous. Legs moderate. Middle and posterior tibiae slightly
spinulose externally, the anterior obliquely grooved, the inner spur above the
apex. Tarsi slender.

This tribe contains the three genera quoted above, and I suspect
that some if not all of those placed by Chaudoir in his Migadopidae
should be added unless the ligular structure is allowed to have weight
in their separation. The affinities of the tribe are feeble except in the
direction of the Nebriini.

AMERICAN COLEOPTERA. Ill

The genera are separated in the following manner :

Mentum tooth large, nearly as long as the lateral lobes, emarginate. Thorax
without lateral seta. Elytra with variolate fovese, not striate. ..Elaplirus.
Mentum tooth short bifid at tip. Thorax with lateral setigerous puncture.

Head not suleate, elytra with feeble striae of punctures Diachila.

Head with deep lateral grooves, elytra striate with interstrial foveiB...Bletliisa.

Elaphrus. — The affinities existing between this genus and Opisthius
have been referred to in the proper place. It is remarkable that the
lateral seta of the thoi-ax is absent in all the species of this genus except
viridis Horn, which is the only one in our fauna with the thorax wider
than the head including the eyes. In the larger species the nudes have
four joints dilated, in the smaller but three.

Diachila. — Two species occur in our fauna, arctica Gyll., common
to both Europe and America, and mhpolaru Lee, from Hudson's Bay.
The anterior tarsi of the male have four dilated and spongy pubes-
cent joints and in mhpolaris the middle femur has a small tooth near
the base.

Blethisa. — Four joints of the anterior tarsi are slightly dilated and
spongy pubescent beneath in the male, and in quadricollis Hald., the
anterior femora have an acute tooth beneath.

Tribe VIII. Loricerini.

Anteunaj sleiuler, base free, first four joints glabrous, first joint elongate, third
longer than second, joints 2—6 with long bristles in front. Eyes round, prominent.
Head forming a distinct neck and with one supra-orbital seta. Labrum moderately
prominent, arcuate in front. Maiulibles thin, curved, acute at tip, without setiger-
ous puncture. Maxillae with a moderate foliaceous expansion at base which bears
long cilise, inner lobe hooked at tip, sparsely ciliate within, outer lobe with slender
joints, palpi slender the last joint longer than the preceding and acute. Mentum
moderately emarginate with an obtuse tooth, basal suture distinct. Ligula not
prominent, slightly prolonged in front and bisetose, the paraglossse adherent in
their entire length and not longer, the palpi slender the last two joints nearly
equal, the penultimate bisetose in front. Thorax transversely cordate, with a
single setigerous puncture at the side behind the middle. Body not pedunculate,
scutellum distinct. Elytra margined at base, sides narrowly intlexed, lateral margin
entire but with a distinct internal plica. Prosternum not prolonged behind, the
anterior coxal cavities closed. Mesosternum oblique not carinate in front. Meta-
sternal side pieces distinct the suture between them well marked, posterior coxa;
contiguous. Legs slender, middle and hind tibiae spinulose externally, anterior
tibise deeply emarginate within, the inner spur remote from the apex. Tarsi
slender.

The anterior tarsi of the male have three joints rather broadly dilated and
densely spongy pubescent beneath.

This tribe contains but one genus Loricera, in our fiiuna, with
which ElUptosoma Woll., a Maderan form has been associated. These
are said to differ in the absence of metasternal epimera in the former

112 GEO. H. HORN, M. D.

and their presence in the latter, but in all the specimens of Loricera
I have examined the suture between the episterna and epimera are
quite distinct.

Associated for a time with the Panagaeides, Loricera has been properly
removed by Schioedte, Schaum and Chaudoir. While it must be con-
sidered a member of the present sub-family allied to the Elaphrini and
Nebriini, it presents two striking characters at variance with all the tribes
of Carabinae and which approach it to the Harpalinae, the deeply emar-
ginate anterior tibiae and the presence of the internal elytral plica which
is so well marked in Pterostichini and Panagaeini.

Tribe IX.— Nebriini.

Antennje with four basal glabrous joints, inserted under a slight frontal plate
which is not extended backward over the eyes in a supra-orbital ridge. Eyes
round, moderately or very prominent, distant from the buccal opening beneath,
less however in Leistus and Notiophilus. Head horizontal (front deflexed in
Opisihius and with two supra-orbital setae), and with one supra-orbital seta. Parts
of mouth variable, mandibles always with setigerous puncture. Thorax usually
with a setigerous puncture at the side and hind angle, both are absent in Opisthius,
and the posterior in Leistus. Elytra margined at base except in Opisthius, sides
narrowly inflexed, margin entire. Prosternum horizontal and prolonged behind
the coxse, the cavities open behind; lateral suture of thorax beneath normally
distant from the margin except in Opisthius. Mesosternum carinate in front.
Metasternal epimera indistinct, posterior coxae contiguous. Legs slender, middle
and posterior tibise spinulose or ciliate externally. Tarsi slender, ciliate beneath.

The parts of the mouth are so variable that I will give in brief the
principal characters :

Leistus. — Labrum prominent, arcuate at tip. Mentum feebly emar-
ginate with a short emarginate tooth. Ligula prominent narrowed at
tip and then trifurcate, bisetose behind the trifurcation, the paragloss^
short with their tips free. Labial palpi long and slender the second
joint longer than the last, without setae in front. Mandibles broad,
explanate at the sides, acute at tip. Maxillie with slender processes on
the outer side of variable length each bearing a stiff seta at its tip, the
palpi slender. The first three joints of the anterior tarsi of male are
dilated and with squamules beneath.

Opisthius. — Labrum short, transverse, more prominent at middle.
Mentum moderately emarginate, the tooth moderately long with nearly
parallel sides, feebly emarginate at tip. Ligula small concealed behind
the mentum tooth, narrowed at tip, slightly bifid and bisetose, the
paraglossae slender arcuate and longer than it. Labial palpi slender the
last two joints nearly equal, the terminal finely ciliate externally, the
preceding bisetose in front. Maxillfe ciliate within, the palpi slender.
Mandibles rather stout arcuate and acute at tip, outer side not concave.

AMERICAN COLEOPTERA. 113

Anterior tarsi of male with four joints feebly dilated and densely spongy
pubescent beneath.

NoTiOPHiLUS. — Labrum moderately prominent arcuate in front.
Mandibles stout not prominent, acute at tip. Maxillae feebly ciliate
internally the palpi moderate the terminal joint but little longer than the
preceding. Mentum moderately deeply emarginate, the tooth notched,
ligula prominent, the tip slightly prolonged and bisetose, paraglossae
slender, arcuate, longer than it, the palpi with last two joints nearly
equal, the penultimate bisetose in front. The first three joints of the
anterior tarsi are feebly dilated and spongy pubescent beneath.

Nebria. — Labrum truncate or feebly emarginate. Mandibles acute
at tip, not concave externally. Maxillae ciliate at base, the palpi slender
the terminal joint a little longer than the preceding. Mentum deeply
emarginate with a bifid tooth, lig-ula not prominent the tip truncate or
slightly prolonged and bisetose, the paraglossae usually adherent in their
entire extent, sometimes slightly free at tip, the palpi moderate, the
penultimate joint bisetose in front. The anterior tarsi of the males have
three joints feebly dilated and pubescent beneath.

Pelophila. — Characters nearly as in Nebria with the last joint of
the palpi more oval. First three joints of anterior tarsi of male rather
broadly dilated and densely pubescent beneath.

The above characters seem to show the danger of attaching too great
value to characters drawn from the ligula and paraglossae as a basis for
the arrangement of the genera of Carabidje.

In Notiophihis the anterior tibiae are very obliquely truncate the
inner spur above the apex. In the other genera both spurs are terminal
but placed slightly obli((uely to each other.

The genera which occur in our fauna Ijclonging to this tribe are
as follows :
Front deflexed, head with two supra-orbital setse, spurs of anterior tibire terminal.

Elytra with oeellate fovese, not margined at base Opistllius.

Front horizontal, head with one supra-orbital seta. Elytra margined at base.

Anterior tibise very obliquely truncate, the inner spur above the apex. Vertex
sulcate Notiophilns.

Anterior tibife scarcely obliquely truncate, spurs terminal.

Mandibles explanate at the sides, maxillse at base with spine-bearing pro-
cesses L.eistus.

Mandibles stout, not explanate, maxillse not appendiculate and merely setose
at base.

Anterior tarsi of male feebly dilated Nebria.

Anterior tarsi of male broadly dilated Pelophila.

In addition to the peculiarities already mentioned it might be observed
that while all the genera above mentioned (except Nofiophilus), place

TItANS. AM. ENT. SOC. IX. (24) AUGUST, 1881.

114 GEO. H. HORN, M. D.

their antennae backward over the body in a more or less curved position
when in repose, in Notiophiius the antennae are bent down under the
head and encircle the margin of the eye.

The affinities of this tribe are more marked in the direction of the
Elaphrini than elsewhere, and it may be e.specially observed that all
those characters which separate Opisthius from the other genera are
found in ElapJirus, the ligula and paraglossse of these two genera are
also similar.

Baron Chaudoir (Bull. Mosc. 1861, i, pp. 492 and 502), separates the
above genera making N'otiophilus a separate tribe and placing the others
as a sub-tribe of Carabini. If it be considered advisable to divide
the above tribe, Opisthius and Notiophilus are equally worthy of repre-
senting distinct tribes. The union of the tribe with Carabini seems
to me unnatural from the appearance of the genera as well as from
their characters.

Tribe X.— Migadopini.

Autennse slender, arising under a slight frontal ridge, four basal joints glabrous.
Eyes round, not prominent, moderately distant from the mouth beneath. Head
short, broadly oval, clypeus distinct and with a setigerous puncture each side
distant from the margin, one supra-orbital seta. Labrum short, truncate, quadri-
setose in front and ciliate at the sides. Mandibles acute at tip, feebly arcuate,
without setigerous puncture externally. MaxilL-e arcuate at tip, spinulose within,
outer lobe biarticulate, palpi stout, the terminal joint somewhat oval, obtuse at tip.
Mentum short and broad, emarginate, with a broad emarginate tooth nearly as
long as the lateral lobes, ligula oval, bisetose at tip, the paraglossaj moderately
broad and adherent in their entire length, palpi moderate, terminal slightly longer
and truncate at tip, the penultimate bisetose in front. Thorax broad, hind angles
distinct, no lateral setae. Elytra slightly margined at base, sides narrowly inflexed,
margin continuous. Prosternum acute at tip and prolonged, concave beneath and
covering the middle of the mesosternum, anterior coxa? closed behind. Middle
coxse moderately separated, the mesosternal epimera very indistinctly separated
from the episterna but attaining the coxal cavity. Metasternal epimera indistinct,
posterior coxae contiguous. Legs moderate. Anterior tibiae obliquely grooved
within at tip, outer edge slightly spinulose, the inner spur above the apex.
Middle and posterior tibiae spinulose externally, the spurs moderate in length.
Tarsi moderate in length, the first joint not longer than the second.

In the specimen before me of Migadops (Brachycselus) virescens
the anterior and middle tarsi of the male have four joints dilated and
papillose beneath.

Through the great kindness of my friend jMr. H. W. Bates, I have
been enabled to examine the specimen above indicated. I regret that
I have been compelled to define the tribe in a somewhat incomplete
manner but there will be no difficulty in assigning a place here to those
genera whose affinities indicate it.

AMERICAN COLEOPTERA. 115

The tribe as defined by Chaudoir (Bull. Mosc. 1861, i, p. 510), is
certainly composed of very dissimilar material and I have removed
Metrius to form a distinct tribe the reasons for which will be found in
the proper place.

The genera referred to this tribe by Chaudoir (omitting Metrius),
are — Anfarctonomus, Brachycselus and Migadops from Tierra del Fuego,
Monolohus and Rhytidognathus from Chili, Lissopterus from Falkland
Islands, and Heferodactylus from Auckland.

Monolohus is remarkable in having the outer maxillary lobe of one
piece as in AmpMzoa.

The tribe seems very naturally to lead from the Nebriini to the
Metriini.

Migadops virescens Waterh., has considerable superficial resemblance
to Nehria virescens Horn.

Tribe XL — Metriini.

Antennfe moder.ate in length, straight, arising under a distinct frontal margin;
first four joints glabrous, the first joint stouter but not longer than the third, 5 — 11
subequal, pubescent. Eyes small, round, distant beneath from the buccal opening.
Head with a single setigerous puncture over the middle of each eye. Labrum
short, feebly bisinuate. Mandibles short, concave on the outer side and with a
distinct setigerous puncture. Mentum transverse broadest at middle, deeply eniar-
ginate and with a rather stout, bifid tooth, epilobes distinct, mental suture well
marked. Ligula broad, obtuse and bisetose at tip, the paraglossse distinct and
adherent in their entire length ; palpi rather stout, the last two joints of nearly
equal length, the second bisetose in front, the third broader to apex and truncate.
Maxillae with inner lobe rather short, distinctly hooked at tip and ciliate internally,
the outer lobe biarticulate and with equal joints; palpi rather stout, the terminal
joint nearly as long as the second, gradually broader to tip and obtuse. Thorax
transverse, a seta at point of greatest width another in front of the hind angles.
Bases of thorax and elytra in close apposition, scutellum indistinct. Elytra not
margined at base, moderately inflexed at the sides, the margin acute and entire.
Anterior coxal cavities closed behind, prosternum slightly prolonged and partly
covering the declivous and flat mesosternum. Femora moderately stout, the
anterior scarcely thicker. Anterior tibife obliquely grooved and emarginate near
the apex, both spurs terminal. Middle tibiae ciliate externally. Posterior coxae
separated by a rather broad triangular process of the abdomen. Tarsi moderate,
first joint longer than either of the three following, fourth not emarginate.

The first joint of the anterior tarsus of the male is rather broadly dilated and
with the second densely spongy pubescent beneath.

The metasternal side pieces of which no mention is made above are
sometimes simple, that is, with all trace of suture between the episternum
and epimeron obliterated or the suture may be more or less distinct and
the side pieces consequently double.

The genus Metrius is the only one known to me wliich finds a place
in the present tribe. It is a very distinct type the affinities of which

116 GEO. H. HORN, M. D.

are not easy to define. The posterior coxae being separated a relationsliip
seems to be indicated with the Promecognathini and Cychrini, especially
with the latter by the more widely inflexed sides of the elytra but it
differs widely from either by the structure of the anterior tibias. The
presence of a setigerous puncture on the mandible is a very curious
addition to the other characters, as I observe that this is in nearly if not
quite all other cases associated with riparial habits which cannot from
my observation be said of Metrius.

Chaudoir (Bull. Mosc. 1861, i, p. 510), places the present genus in
his tribe Migadopidae, and while but one other genus of that tribe is
known to me I feel very safe in saying that the present can not be
allowed to take place with it. In the synoptic table the structure
of the metasternal side pieces is used for the separation of Migadops
( Brachycaelus) from Metrhis. In the specimen of Mig. virescens before
me the met-epimera are not distinct while in Metrius the suture is
sometimes visible and in others not.

Tribe XII.— Mystropomini.

Antennse arising under a slight frontal jilate, four basal joints glabrous. Eyes
small, round, not prominent, distant from the mouth beneath. Head oval, with
two small supra-orbital setse. Clypeus rather large with two small setigerous
punctures each side. Labrum short, sinuate in front and plurisetose. Mandibles
acute at tip, feebly arcuate, toothed at middle, no setigerous puncture externally.
Maxillae arcuate and acute at tip, spinulose and ciliate internally, outer lobe
biarticulate, palpi rather stout, the terminal joint longer, flattened, broader ex-
ternally with the tip rounded. Mentum large, deeply emarginate and with a
large median emarginate tooth, ligula cuneiform suddenly broader in front, the
tip slightly prolonged in front and sexsetose. paraglossse rather broad, adherent
in their entire length and obtuse at tip, the palpi stout, terminal joint as in
the maxillary. Thorax without marginal setse. Elytra not margined at base,
(scutellum indistinct), sides rather widely inflexed, margin entire not interrupted."
Presternum obtuse at tip, not prolonged, anterior coxal cavities closed behind.
Mesosternum narrowly separating the coxse, the epimera indistinctly separated
from the episterna but distinctly reaching the middle coxal cavities. Metasternal
episterna short and broad, the epimera distinct, posterior coxse separated. Legs
moderate in length. Anterior tibise deeply obliquely grooved within the spurs
both terminal. Middle tibise ciliate with_ short depressed hairs externally and
within, the outer edge of posterior tibise not ciliate, the tibial spurs rather short.
Tarsi slender, the first joint as long as the two following.

The tarsi are said by Chaudoir to be similar in the sexes.

For a specimen of Mystropomus subcostatus Chd., the only known
member of the present tribe, I am indebted to Mr. H. W. Bates.

Of all the genera which I have studied this has caused me the greatest
surprise from the position in which it is placed and which appears to be
now accepted without (juestion.

AMERICAN COLEOPTERA. 117

Mystropomus is now placed at the head of the tribe Ozaenini by
Chaudoir, but the reasons why it should not be placed there are very
many. In the discussion of that tribe will be found the reasons for
removing it from association with the true Carabin^e. The mesosternal
epimera do not reach the middle cosal cavities as one can prove by
softening the specimens in a solution of caustic potassa when the sutures
become evident and mere plications of the surface obliterated.

In Mi/stropomus however we have a structure of body resembling
very closely Metrius not only in the inflexed sides of the elytra but
their general appearance. The epimera and episterna of both segments
are likewise constructed on a similar plan and the posterior coxae sepa-
rated. On comparing the form of head and antennae and even the
mouth parts we have a striking analogy with Metrius. I am disposed
to consider Mi/stropomus^ the closest ally in every respect with Metrms
and with Migadops an intermediate link toward the Nebriini.

It is remarkable that this genus should occur in Australia. Lacordaire
(Atlas pi. 5, fig. 5K gives an illustration of the species which might
however be improved.

Tribe XIII.— Promecognathini.
Antennse slightly geniculate, arising under a slight frontal margin, first four
joints glabrous, the first much larger and stouter than the others, 5 — 11 slightly
compressed and finely pubescent. Eyes small slightly oval and distant from the
buccal opening. Head with two supra-orbital setse, neck slightly broader behind
the eyes. Labrum short, bisinuate. Mandibles elongate, arcuate and acute at tip
and decussating, not toothed within. M'entura short, broad, broadly emarginate
and with a broad short tooth, epilobes narrow but distinct, mental suture distinct.
Gula deeply transversely impressed so that the mentura is inserted at a right angle
to the peduncle. Ligula moderately prominent narrower and free at tip, truncate,
with two setae, paraglossse long, rather slender and ciliate within at the tip.
Maxillae with inner lobe slender and long, obtuse at tip, densely ciliate within,
outer lobe biarticulate the terminal joint much shorter. Maxillary palpi moder-
ately long, the second joint equal to the next two together, terminal joint broader
at tip truncate and twice the length of the third. Labial palpi with the last two
joints about equal in length, the terminal broader at tip and truncate, the pre-
ceding bisetose in front. Thorax narrowed at base, sides narrowly inflexed, lateral
margin distinct, a setigerous puncture near the hind angle and three at the side
in front. Body pedunculate, scutellum invisible. Elytra not margined at base,
lateral margin distinct and entire, sides narrowly inflexed. Anterior coxal cavities
closed behind, prosternum not prolonged, mesosternum declivous. Metasternal
epimera indistinct. Femora stout, the anterior more strongly clavate. Anterior
tibire gradually broader to tip, smooth externally, deeply emarginate internally,
the inner spur remote from the tip. Posterior coxae separated by a triangular
process of the abdomen which meets the metasternum. Tarsi moderate, the
posterior longer, first joint moderately long, fourth slightly emarginate. Tarsi
similar in the sexes.

118 GEO. H. HORN, M. D.

The above characters which I have drawn entirely from our only
representative should be somewhat modified by the omission of the
descriptions of the palpi and other parts which may be considered purely
generic. The description is rather detailed in order that the omissions
in previous descriptions of Promecognathux may be supplied.

This tribe as typified by our genus has been the subject of some
discussion and very diverse opinions have been expressed regarding its
systematic position. From my own study I feel convinced that the views
expressed by LeConte (Class. Col. N. A. p. 12), are correct.

As far as known to me two genera only belong to this tribe, as

follows :

Last joint of maxillary palpi oblong-oval truncate Proinecogitatlius.

Last joint of maxillary palpi strongly securiform Axiiiiclium.

These two genera are placed by Lacordaire (Genera i, p. 247), in a
tribe which owes its origin to Chaudoir, (Bull. Mosc. 1846, p. 511),
composed as very justly observed by Schaum (Berl. Zeitschr. 1860,
p. 178), of very dissimilar material, held together it may be added by
a bond of the feeblest nature. The positions of the other genera will
be discussed in their proper places and the correctness of Schaum 's
views shown except as to Glyptu^^ which has very little to do with the
Orthogoniens but far more with the Harpalini.

As restricted above the tribe falls very naturally between the tribes
which precede and the Scaritini.

Promecognathus occurs in California, Axinidium in western Africa.

Tribe XIV.— Enceladini

Antennae moderate in length, straight, arising under a distinct frontal margin ;
first four joints glabrous, the first joint stouter suddenly narrowed at base, second
equal in length, 3—11 gradually shorter and more slender. Eyes comparatively
small, round and distant from the buccal fissure. Head with a single setigerous
puncture over each eye. Labrum moderately prominent, arcuate at the sides and
feebly emarginate at middle. Mandibles stout, arcuate, a large tooth near the
base, outer side deeply grooved and without setigerous puncture. Maxillae with
inner lobe strongly hooked at tip and with short spinules on inner edge, outer
lobe stout biartieulate, the palpi stout, second joint longer than the others, the
terminal broad, oboval. Mentum large without distinct suture at base, broadly
arcuate at the sides, deeply emarginate and with a moderate tooth emarginate
at tip, epilobes distinct. Ligula prolonged in a broad obtuse point, bisetose, the
paraglossaj corneous and closely united it; labial palpi moderate, the terminal
joint somewhat triangular and arcuately truncate at tip. Thorax broad, a seta at
the side another in front of hind angle. Body pedunculate, scutellum forming
the larger space of the peduncle above. Elytra not margined at base, the lateral
margin entire and very narrowly inflexed. Presternum obtuse at tip, not pro-
longed, the coxal cavities closed behind. Mesosternum broad convex and oblique.
Metasternal opimera indistinct, the posterior coxa; distinctly sejtarated l)y a narrow

AMERICAN COLEOPTERA. 119

abdominal process. Femora moderate and nearly equal. Anterior tibife gradually
broader to tip, grooved on the inner side near the tip, the spurs nearly on the
same line transversely. Tarsi moderate in length, the first joint longer, the fourth
not emarginate.

The tarsi do not differ in the sexes.

As in the other tribes of the present sub-family which contain but
one or two genera, the description of the present is made with con-
siderable detail drawn entirely from the typical genus, the only one
known to me in nature. In the books Enceladus is placed with Siagona,
a genus with which it seems to have very little relation except the large
mentum without suture at base. Schioedte and Chaudoir have been
deceived by a line of sculpture and have placed the Siagonides as a
whole in the present sub-family. I do not find the mesosternal epimera
attaining the coxae in Siagona while they do very plainly in Enceladus.
Another character used by Schioedte is of very doubtful utility " antennse
scrobicuiis recipiendse" the antennal grooves or scrobes being merely the
result of the dilated genal plates which are variable within generic limits,
and have already been made use of by me in separating the species of
CycTirus in subgeneric sections.

Not knowing Luperca"^ in nature I am unable to say whether it
enters the present tribe or not, should it be as closely allied to Enceladus
as stated by Lacordaire the two genera form a very distinct type equal in
value to the Metriini or Promecognathini and with its affinities but little
better marked. Lacordaire perceives relationships with the Oza^nides,
Galeritides and Scaritides, but these entirely escape me except as to the
last of these tribes, to which there is but little resemblance except in
external form. I believe however it is better placed near the Scaritini
than anywhere else in the series.

Enceladus occurs in Colombia and Gruiana, Luperco in the East Indies.

Tribe XV. -Scaritini.

Antennae moderate in length, inserted under a frontal plate with a variable
number of glabrous joints. Eyes comparatively small very finely granulate and
distant from the buccal opening (Scarites), or normally convex and granulate and
not distant from the mouth (Clivinse). Head variable in form and with one
(Scarites) or two (Clivinse) supra-orbital setae. Labrum short, emarginate or
sinuate. Mandibles at least moderately prominent, without setigerous puncture,
simple or dentate. Maxillse with the inner lobe often obtuse at tip, in some
genera normally hooked, ciliate or spinulose within, outer lobe biarticulate the
terminal joint usually shorter, palpi variable in form. Mentum emarginate, often
deeply, the tooth variable in size, epilobes narrow, but very wide in Schizogenius.

* Chaudoir replaces this name by Holoscelis Chd. For other remarks which
may properly be read as a supplement to the present tribe, the reader is referred
to the Siaffonini.

120 GEO. n. HORN, M. D.

Ligula either broad and large (Scarites) or small and prolonged (Clivinse) the tip
narrow and bisetose, except in Pasimachus in which it is but little prominent at
middle and with the two setse very closely approximated, paraglossse usually
slender and longer than the ligula, spinulose within in the Scarites. Palpi moder-
ate, terminal joint variable in form, shorter than the penultimate (Scarites) equal or
longer (Clivinse), the penultimate bisetose in front (Clivinise) plurisetose (Scarites).
Thorax variable in form, hind angles rarely prominent, side margin with a setiger-
ous puncture in the hind angle (Scarites) or with two lateral punctures (Clivinse).
Body pedunculate, scutellum not visible between the elytra. Elytra rarely slightly
margined at base, sides narrowly inflexed margin entire except in Ardistomis
where there is a distinct interruption posteriorly and an internal plica. Prosternura
not prolonged behind the coxae, the cavities closed behind. Mesosternum vertical,
not carinate in front. Metasternal epimera not visible in Pasimachus, more or less
distinct in all the other genera. Posterior coxse contiguous. Legs stout more or
less fossorial, the anterior femora especially stout. Middle and posterior tibiae
ciliate or spinulose externally but often very finely, anterior tibise palmate the
outer apical angle prolonged, inner side deeply emarginate with the inner spur
above the emargination. Tarsi slender.

From the above characters it is evident that the tribe must be sub-
divided into two groups in the following manner :

Basal joint of antennae long. Mentum broad, concealing at the sides the base of
the maxillae. Head with one supra-orbital setigerous puncture, thorax with

one setigerous puncture at the hind angle Scarites.

Basal joint of antennae not elongated.. Base of maxillae not covered by the
mentum. Head with two supra-orbital setigerous punctures, sides of thorax

with two Clivin^.

In addition to the above characters the form of the labial palpi and
the paraglossEe give additional means of separating the groups.

The sexual characters of the genera of this tribe are very feeble.
In Scarites the last ventral segment has four marginal punctures,
in the female the inner two are more distant from each other than
from the outer, while in the male they are equidistant. In Pasi-
machus some species have the posterior tibiae pubescent within at tip
in the male. There are no marginal punctures on the last ventral
segment, in the males there will usually be observed on each side one
ante-apical puncture and in the females two, but these are not constant
in any respect.

In the Clivinae the last segment is the same as in Scarites, the
tarsi are often alike slender in both sexes but when dilated are
more so in the male. In DyscMrius the palpi differ as will be seen
below.

The antennse vary in the number of glabrous basal joints, the Scarites
have four and the Clivinae two. In Aspidoglossa the base of third is
glabrous but even here as in all the Clivinse the second joint though not
pubescent is hairy.

Group SCARITES.

In our fauna two genera occur separated in the following manner :

Hind angles of thorax distinct. Elytra with humeral carina of variable length.

Maxillse very obtuse at tip Pasimachus.

Hind angles of thorax wanting. Elytra without humeral carina. Maxilla? slightly

hooked at tip Scarites.

In these two genera the four basal joints are glabrous and in repose
the scape is received in a depression beneath the eye.

Group CLiviNiE.

The genera which occur with us are as follows :

Margin of elytra entire. Mandibles flat and arcuate.
Anterior tarsi slender in both sexes.

Palpi dissimilar in the sexes, the terminal joint more dilated in the male,
excavate beneath with a large sensitive space. Thorax globose or globose-
oval Dyschirius.

Palpi similar in the sexes, not dilated nor excavated in the male. Thorax

more or less quadrate CI i Vina.

Anterior tarsi more or less dilated in both sexes.

Mentum feebly emarginate. Head not grooved Aspifloglossa.

Mentum deeply emarginate. Head with numerous longitudinal grooves.

Scliizogenius.

Margin of elytra interrupted posteriorly and with an internal j)lica. Mandibles

slender, prolonged not arcuate. Anterior tarsi of both sexes rather

widely dilated Ardistoniis.

In the arrangement of the genera of this group I regret that I am
unable to follow my friend M. Jules Putzeys, nor can I from my
dissections find the ligular characters which he aims to illustrate in
his Postscriptum (Mem. Liege xviii, 1863). The dissection of the
species of this group is by no means an easy task, and the difficulties
attendant on its accomplishment must be the cause of the entire
absence of resemblance between the drawings of M. Putzeys and the
objects themselves.

In all our genera the ligula is small and is usually hidden by
the supports of the labial palpi. The ligula is slender, the tip more
or less acute, free and biseti'gcrous the paraglossse slender and acute,
not longer than it. The form of the maxillae, mentum, ligula and
palpi, are shown in the accompanying figures and need no further
description. Clivina and Dyscliirius are best separated by the form
of the palpi, all other characters heretofore given fail in our series
of species.

As arranged in the preceding table our genera show the transition
from the simple form of inner maxillary lobe of PasimacJms to that
which is the more common form in all Carabidse.

122 GEO. H. HORN, M. D.

It is curious in this tribe that Ardistomis should "have the elytral
margin interrupted with an internal plica. It thus shows considerable
more affinity with the HarpalinEe than do the other genera and seems
to be the nearest Carabine relation of the Panagaeini, in place of the
Cychrini as suggested by most authors.

Sub-Family UARPALINjE.

Middle coxal cavities entirely enclosed by the central pieces of the
meso- and metasternum, the epimera not attaining the coxae. Head
with setigerous punctures over the eyes. Thorax with setigerous punc-
tures at the side and posterior angle very rarely without the latter
and still more rarely without either. Anterior tibiae always either
obliquely sinuate or deeply emarginate within, the inner spur remote
from the apex.

These characters seem to be the only ones in which all the tribes
agree. As there are many points in which wide differences occur these
will be left for discussion in their proper places.

For convenience of study the sub-family may be divided in two
grand sections.
Head with two supra-orbital setigerous punctures.

Harpalinje bisetos^.
Head with one supra-orbital setigerous puncture.

Harpalin^ unisetos^.

Small as this character may seem it is probably one of the most
invariable of any that have been suggested for the division of any large
series of genera or tribes. I have never observed an exception, although
Bedel * says that in two European Amara one has but one supra-orbital
seta (^spectabilis) and the second (^pyrenxa) none whatever.

When two setae occur the anterior is close to the margin of the
eye in front, the posterior is a little remote from the eye opposite the
posterior margin. When there is one seta it is almost always a little
removed from the margin of the eye and is situated opposite the middle
of the eye or a little posterior to that point.

The Harpalinae as here constituted seem to be the true development
of what might be called the Carabide idea of the present geological
period. There is evidently a close relationship in the entire series with
fewer breaks in the line of affinity and with very few genera that are
abnormal or* specially differentiated in the sense in which we observe

Ann. Fr. 1870, suppl. p. 52, note.

AMERICAN COLEOPTERA. 123

it in the Carabiriae. It will be observed in glancing over the series of
tribal and genera that there are three well marked types, Fterostichus,
Lehia and Harpalus, closely related among themselves around which
we may group other types either more or less intermediate between the
three or related to them as a centre and from thence diverging with
no definite affinity. It is therefore impossible to construct any linear
arrangement which will exhibit all the evident relationship without at
the same time interrupting other equally evident afiinities.

The tribes which follow are so placed that those which seem to exhibit
the closest relationship with the Carabinae are at the beginning with those
following which seem to lead to the true Harpaline type.

Those with the two supra-orbital setae will be considered first and for
convenience of reference will be called by the following name.

Harpaline bisetos^.

This section contains by far the larger number of tribes and genera
and presents many difficulties in its study. Many of the characters used
in the table are the common property of science others are new or have
been brought into greater prominence for the first time here. To those
acquainted with the literature of the subject no special references are
needed.

As in the Carabinae it appears to have escaped notice that a number
of genera have the posterior coxae separated and the metasternum and
abdomen meeting. This is an important character and its use is attended
with good results.

The internal elytral plica by its presence serves to separate a number
of tribes. The object of this structure is to afford a means of >support
to the edge of the abdomen and at the origin of the plica posteriorly
the last ventral segment is firmly held when in repose. It will be
observed that in those genera with a plica the upper edges of the
ventral segments are vertical, those without the plica have the edge
inflexed. As a rule the pliciferous genera are terrestrial and are at best
feeble flyers, the majority of the others are easy flyers and less terrestrial
in their habits. This however is merely a general statement with many
exceptions on both sides.

The tribe P a n a g ae i n i is placed at the head in the belief that some
of its members will show a closer relationship with the Clivinse than has
yet been indicated.

The table which follows is the result of a study not only of the
genera of our fauna but of all which were accessible, the cabinets of
the Academy of Natural Sciences, supplemented by that of our own

Society have afforded an amount of material wliich had never been
properly estimated. Many of the genera will be found mentioned "in
the following pages, but only those which seemed to require it and
which are but a part of those actually studied.

Those who know the extent of the subject will properly esti-
mate the amount of labor expended and with the hope that the
table will prove an incentive to additional work with many improve-
ments and emendations, it is presented for the consideration of those
interested.

12G GEO. II. HORN, M. D.

Tribe XVI.— Panagseini.
Antennae slender arising under a distinct frontal ridge, three basal joints
glabrous, without fine punctuation and pubescence, but ciliate. Head usually
constricted behind the eyes and dilated to a semiglobular neck, front with two
supra-orbital setse. Eyes round, rather prominent, distant beneath from the buccal
opening. Labrum with four setse only. Maxillse small the inner lobe slender,
hooked at tip ciliate or spinous within, outer lobe stout, biarticulate, palpi elongate
the last joint triangularly dilated and inserted obliquely on the preceding, these
two hairy. Mentum emarginate, toothed at bottom, the basal suture distinct.
Ligula moderately prominent, bisetose at tip the paraglossse adherent and rarely
longer than it, palpi moderate in length the terminal joint triangular. Thorax
variable in form. Body not pedunculate, scutellum distinct. Elytra not margined
at base, sides narrowly inflexed, margin interrupted posteriorly and with an
internal plica. Prosternum not prolonged. Mesosternum' oblique, the epimera
very narrow. Metasternal epimera distinct, posterior coxse contiguous. Tibite
ciliate externally, the anterior emarginate within, the spurs distant. Tarsi slender
in our genera, the fourth joint bilobed in certain exotic genera.

The males rarely have the anterior tarsi dilated. In our genera the first two
joints of the anterior tarsi are dilated and hairy beneath.

Of late years authors seem pretty well in accord as to the limits of
this tribe. Lacordaire included Loricera which has already been dis-
cussed. To the tribe as left by the latter author Schaum ( Ins. Deutschl.
i, p. 318), added Tcjflus, and Disphrxricus which however is not included
by Chaudoir in his essay on the tribe (Ann. Belg. 1878). I have not
seen the latter genus in nature. Geohius included by Lacordaire is
excluded by Chaudoir for reasons which seem scarcely more than of
generic value. I cannot see any relation with Pelecium.

Chaudoir in the characters of the tribe has the following paragraph :

" Machoires crochues et tres ciliees en dedans, lobe inferieur a dernier
article court, tr^s large, comprime et termine par un petit crochet
( excepte 'dans le genre Micrixyi).'"

I can find no such character as that mentioned for the outer maxillary
lobe and if it did exist would be uniqiie in the tribe and extraordinary
in the entire family.

The affinities of the tribe are not well marked in any direction, it
appears in fact to stand more nearly alone than any tribe of the present
sub-family, and I have already expressed the opinion that its affinities
with the Carabinae are rather through the Clivina? than the Cychrini.
I can see no reason for suspecting any relationship with the Chlaeniini.

Two genera occur in our fauna which, difi^r in the following manner :
Clypeus prolonged beyond the base of the mandibles, the latter decussating,

scissor-like Pauagseiis.

Clypeus emarginate at middle, the mandibles stout, pincer-like Micrixys.

The latter genus has the head not distinctly constricted but the neck
is of the same semi-srlobular form as in the former.

AMERICAN COLEOPTERA. 127

In both genera the ocellate punctures which are usually observed
near the margin of the elytra in Carabidfe are absent, but are present
in other genera of the tribe. I have observed also that they are absent
in Apotomus, a genus not related to the present tribe.

Tribe XVII.— Siagonini.

Antenn* slender, arising; under a distinct frontal plate, first joint elongate
conical pilose, second short glabrous at base, 3 — U equal and, with the apex of
the second, pubescent. Clypeus prolonged at middle. Head depressed, quadrate,
two approximated supra-orbital setse. Eyes small oval, truncate posteriorly, very
distant beneath from the buccal fissure. Labruni sinuate or denticulate. Mandi-
bles strongly arcuate, either dentate or simple within, scarcely concave externally
without setigerous puncture. Maxillae ciliate within, the outer lobe with terminal
joint longer, palpi stout, the joints with short hairs, the terminal shorter than the
preceding, oval, truncate at ti[). Mentum large almost entirely concealing the
maxillfe, the suture at base indistinct, deeply emarginate and with a large bifid
tooth, ligula large prominent, slightly emarginate in front and plurisetose, the
paraglossse corneous and closely united with it, palpi moderate, last joint securi-
form. Thorax narrowed at base, grooved above and with a setigerous puncture
on the hind angle and others along the side margin. Body pedunculate. Elytra
elongate-oval, depressed, sides narrowly inflexed, margin entire, base not margined.
Prosternum not prolonged. Mesosternum rather widely separating the coxsp,
horizontal, the epimera narrow and not attaining the coxal cavity. Metasternal
epimera small but distinct. Posterior coxae slightly separated, the first ventral
segment distinct between them. Anterior tibiae emarginate within and deejily
obliquely grooved, the inner spur superior. Tarsi simple in the two sexes.

This group contains but one genus Slngona (possibly also Luperca =
Holosceh's), not represented in our fauna. It has been made by most
authors the type of a tribe and placed in the Carabinfe. The Siagonides
of European authors contains two very dissimilar elements. Enre/adns
and Lnperca (?) having the middle coxfe partially closed extei'nally by the
mesosternal epimera form in the present essay the tribe Enceladini of
the sub-family Carabinje. Siogonn on the other hand has the meso-
sternal structure of the present sub-family and Schioedte, Schaum and
Chaudoir have been deceived by a mere plication in the mesosternal side
pieces and have been lead to believe that the mesosternal epimera reach
the coxae. By macerating a specimen of Stngnna for a sufficient time
in a solution of caustic potassa the sutures become apparent and will be
found as stated above.

The latest review of the Siagonini is that published by Baron Chaudoir
(Bull. Mosc. 1876), in which Evrefadus still retains its place in the
tribe. In recognizing the great value of the discovery (which we owe
to Dr. LeConte), of the diiference in form of the mesosternal epimera in
the sub-families of Carabidae, Chaudoir states that in associating Slngona
with Encehidiii^ one reasons rather by arialogy as the suture which sepa-

128 GEO. H. HORN, M. D.

rates the epimera is so obsolete as not to be distinguished. It is to be
regretted that so able an entomologist should have allowed himself to
perpetuate an error when the truth was so nearly within his grasp and
so easily obtained, and had the above mentioned process (so well known
to microscopists) been made use of, more service would have been done
to science than by many ligular dissections.

If I have correctly interpreted the feeble traces of the suture at the
base of the mentum this organ is not attached merely to the central
gular piece but also to the side pieces of the gula, in a manner similar to
that observed in the Pseudomorphinae. In all other Carabidae which
I have dissected the central gular piece is expanded at tip and forms
the entire basal attachment of the mentum even in those genera with
a very broad mentum.

With a very indefinite relationship with the Pseudomorphinae the
present tribe shows very decided affinities with the Ozaenini.

Tribe XVIIL— Ozeenini.

Antennae arising under distinct frontal plates, the four basal joints not finely
pubescent but hairy. Clypeus prolonged at middle. Head more or less narrowed
behind the eyes to a neck and with at least two supra-orbital setae. Eyes round,
moderately prominent, irregular in outline behind', distant from the buccal open-
ing beneath by the moderately widened genoe. Mentum broad, the suture at base
usually very plainly visible, toothed (except Eusira), ligula moderate or small,
the paraglossse narrow and entirely adherent, the palpi variable in form, the
terminal joint usually cylindrical, flattened and truncate at tip, the maxillary
palpi similar. Thorax with numerous small setigerous punctures along the margin.
Body more or less pedunculate. Scutellum not prolonged between the elytra.
Elytra not margined at base, narrowly inflexed at the sides, margin interrupted
one-third from apex but without internal plica. Presternum not prolonged at tip.
Mesosternum very narrow, in some cases not separating the middle coxas. Meso-
sternal epimera broad, not attaining the middle coxae. Metasternal epimera visible.
Posterior coxae distant, the first ventral segment visible between them. Anterior
tibiae emarginate on the inner side the spurs distant. Tarsi slender, simple in
the two sexes.

The sexual characters are feeble, the males sometimes having the anterior
femora toothed beneath.

By all European authors this tribe has been placed in the series in
which the mesosternal epimera attain the coxal cavities. The idea
originated with Schioedte, has been adopted by Schaum and acknowl-
edged by Chaudoir.

The latter gentleman with his usual sagacity realizes the impropriety of
such a position of the tribe and uses the following language (Ozenides, Ann.
Belg. xi, 1868, p. 3),.in reference to the epimera! character : "un caractere
auquel Schioedte et apres lui beaucoup d'entomologistes ont pendant quel-
que temps attache uiu' iniportaliee ({uc je trouve maintenant exageree."

AMERICAN COLEOPTERA. 129

After a careful examination of Phi/sea and Pachyteles I find that tlie
mesosternal epimera do not attain the middle coxjb, and that no better
evidence is required of the value of the character .than the fact that
these genera and their allies are thereby excluded from the Carabinae.

The value of the character drawn from the mesosternum is certainly
very much overestimated, as it will be observed that while certain species
of Pachyteles {marginicolUs, biguttatus), have the middle coxae as dis-
tinctly separated as in many Platynus, others have the middle coxal
cavities confluent {mexicaiiua). It will be observed however that there
is an unusual degree of flexibility of the central region of the body and
that the articulation between the meso- and metathorax is rather loose.
The lateral process of the central piece of the mesosternum, that is, those
processes which partly enclose the coxae externally, are capable of a slight
motion under the opposite processes of the metasternum and the limit of
this motion is indicated by a slight ridge on the former process, which
ridge is exactly continuous with the suture separating the mes-episternum
from the mes-epimeron and has been the unfortunate cause of the de-
ception of all those who have heretofore studied these parts. For those
who desire to verify the above statements a preparation made in the
manner indicated for Siagoiia will remove all doubts.

The interruption of the lateral margin of the elytra is a character
entirely different from that observed in the succeeding tribes. If the
margin is followed from the apex to the interruption it will be observed
that this end passes over that which is formed by the anterior portion,
while in the Pterostichini, etc., the posterior end passes under the anterior
and is continued oh the under side of the elytron in a long ridge.

The relationships of the Ozasnini are feeble in the direction of
Pseudomorpha and Siogonn^ but more decided toward Nomius and
Pxj/drus which lead through the Morionini to the ccnti'al mass of the
Harpaline series.

Alijstropomu^ placed here liy Chaudoir seen)s to me to lie a true
Carabine allied to Metrius.

One genus is represented in oiir fauna, and the .species Pachi/teles
tesfaceus Horn, occurs in Arizona. Physea has occurred at Tampico,
Mexico, and may possibly be found in Texas.

Tribe XIX.— Nomiini.

Antennae somewhat nioniliform, arising nndei- a distinct frontal ridge, four
basal joints glabrous, first joint stouter not long, third nearly as long as the two
following, terminal oval acuminate. Head stout, oval, neck broad, front with two
svipra-orbital setse, clypeus slightly prolonged. Eyes round, prominent, free pos-
teriorly, closely approaching the buccal opening beneath. Lal)rum short, broadly

tiiurlii'd .-it iniildle, outer Iowit edge slightly expanded, the outer (ace concave and
uiili a di-iinct seiigeriiiis puncture. Maxillie ^Jtout, with a double row of short
stilt' spines within, ])alpi stout, teriuiual joint slightly fusiform and obtuse at tip.
Mentuui broad, deeply emarginate without tooth, basal suture distinct. Ligula
short, broad, aciute and bisetose at tip, the paraglossse slender slightly longer than
it and ciliate within at tip, palpi short, last joint slightly fusiform, obtuse at tip.
Thorax with two setae near the front angles and one at the posterior. Body
pedunculate, scutellum not visible between the elytra. Elytra slightly margined
at base near the hind angles, sides very narrowly inflexed, margin slightly
interrupted posteriorly and with a short internal plica, no dorsal punctures.
Prosternum obtuse, not prolonged at tip. Mesosternum oblique the coxse sepa-
rated, epiinera and episterna nearly equal. Posterior coxae contiguous. Abdomen
with posterior margins of segments 3 — 4—5 narrowly coriaceous. Legs moderate,
middle and posterior tibife ciliate externally, the anterior slightly broader at
tip, emarginate within, tlie spurs distant. Tarsi not dilated. Sexual characters
as in Scarites.

As far as I can ascertain this tribe is represented by a single genus
Nomiua^ (Haplochile Lee), the position of which has been the cause
of differences of opinion. For Dejean, Duval and Schaum it was a
Morionide, Lacordaire (not knowing Haplochile), places Nomius in the
Ozenides and Haplochile in Morionides. Chaudoir properly omits it
from his essay on the Ozenides, while Bedel (Ann. Fr. 1879, suppl.
pp. 24 and 42), places it in his tribe Bembidiini which is part of a very
heterogeneous and impossible sub-family Bembidiidas. Under Psi/drus
will be found its history in our fauna.

From the Morionini it differs in the form of the anterior tibite and
mesosternal epimera and the presence of a mandibular setigerous punc-
ture, the form of the ligula and paraglossoe and the structure of the
abdomen.

The mesosternum is not narrow between the coxa3 but emarginate,
receiving the metasternum and in this- respect differs greatly from the
Ozaenini which have the mesosternum, at most, linear between the coxae
and never wide enough at tip to be emarginate.

I cannot understand why Bedel is willing to place Nomius near
Bembidium, Patrobus, etc., the only point in which it resembles these
is in the presence of mandibular seta. Its affinities seem to me to be
best indicated by placing it between the Ozaenini and the Morionini.

Nomius contains but one species N pi/fjmseus Dej., which occurs in
various parts of southern Europe, and in many places in our country
from Georgia to California.

It occurs under stones, etc., in moist places, and exhales a strong-
fetid odor.

To this tribe two anomalous foreign genera should be referred Mc/prniis

and Coacinia. Thp8e with Nomiuif seem to represent three tirnups in
the tribe. Coscinia lias very little relationship with Sluf/oim execjit a
slight resemblance in a.spcct. All the genera of this tribe as thus detined
have a. well marked elytral plica internally, a character sufficiently re-
stricted in its distribution to indicate more or less ajipmximately tlie
relationship of genera possessing it.

For the privilege of examining these genera I am indebted to
Mr. H. W. Bates.

sternal epimera distinct, posterior coxse contiguous. Ventral segments 3 — 4—5
with posterior margins coriaceous. Legs moderate, the tibise snjooth externally,
the anterior emarginate within, the spurs distTant.

The anterior tarsi do not difier in the sexes, the sexual characters are the same
as in Scarites.

The only genus known to me which can be referred to this tribe is
Psyclrus. Its form is not unlike some Bembidia, the color piceous.

Regretting the multiplication of tribes, I can find no place in which
the genus can be put and atn compelled to adopt the present course and
consider it the type of a tribe the affinities of which are in the direction of
NoTniux and Siagonu, as well as in a less marked degree toward Mario.

Psydrus was originally placed near Ozsena, (Ann. Lye. iv, p. 153),
subsequently with Haplochile (== Nomius), as a group of the tribe
Broscini, a position retained in the Class. Col. N. Am. p. 30, Lacordaire
in the meantime placing it in the Morionini. None of these positions

132 GEO. H. HORN, M. D.

seem to me tenable, Ozjenini having the posterior coxaj separated, Nbmius
tlie body pedunculate and a mandibular seta, Morio the anterior tibiae
dilated and body ♦pedunculate. If we take the ligula as a point of
comparison the resemblance is rather with Pachyteles (which however,
has but two seta3 or Siagona wheje there are six) than with Morio and
Nomius where the paraglossae are long and slender.

The body is not at all pedunculate and* there are two supra-orbital
setae, characters which perfectly exclude it from all association with
Broscini. There can ' be no suspicion of association with Pterostichini
from the differences in tarsal and antennal structure.

There is then no course left but to consider it a distinct tribe leading
directly from the Siagonini, Ozsenini and Nomiini through Morio to
the Pterostichini.

One species of Fsydrus is known ( P. piceus Lee), which occurs from
Lake Superior to northern California. I fou«d it in the latter region
living under dead bark, it ejects a liquid from its anus when disturbed
which is not, like in Nomius^ especially offensive.

Tribe XXL- Morionini.

Antennae more or less moniliform with four entirely glabrous joints, arising
under slight frontal plates. Head suddenly narrowed behind the eyes, neck stout,
front with two supra-orbital setae, clypeus slightly prolonged. Eyes round, moder-
ately prominent, truncate posteriorly by the sides of the head, distant beneath
from the buccal opening. Mandibles at least slightly prominent without setigerous
puncture externally. 'Maxillae ciliate internally (with a tooth behind the apex in
Morio) ; the palpi moderate, the last joint slightly fusiform. Mentum deeply
emarginate, usually with a bitid tooth ; ligula broad, free and bisetose at apex,
the paraglossre slender, longer than it, not ciliate; palpi moderate the last joint
cylindrical (longer than that of the maxillary Morio). Thorax with a setigerous
puncture at each angle (and three at the side Morio). Body slightly pedunculate,
scutellum distinct. Elytra feebly margined at base, sides narrowly inflexed, disc
with a single dorsal puncture at apical third, on the third interval near the third
stria, margin with a very feeble interruption but with a distinct internal plica.
Prosternum not prolonged. Mesosternum rounded in front, the epimera veiy
narrow. Metasternal side piec^es nai-row, the epimera distinct, posterior coxte con-
tiguous. Ventral segments witliput coriaceous margin. Tibiae gradually broader
to apex, the middle tinely spinflose externally, the anterior more dilated, the
apical angle somewhat prolonged, inner side deeply emarginate. the inner spur
above the emargination.

The first three joints of the anterior tarsi are slightly dilated in the male.
The remarks which have been made on the preceding tribes and their
relationship with the present, sufficiently explain the views intended in
the present paper. As constituted by Lacordaire (Genera i, p. 180), the
tribe is a mixture of very dissimilar material. Psydrui^ and Nomius are
already excluded. Schaum (Berl. Zeitschr. 18(30, p. 177), suggests the

AxMERICAN COLEOPTERA. 133

exclusion of Physocrotaphna and its union with the HeUuonini in which
position it appears in the Munich Catalogue. From the figures and
description it seems to me probable that this also is incorrect, while the
details already known to me seem clearly to indicate its afiiuities, but not
knowing the insect in nature it seems unnecessary to venture farther.

Those genera without neck to the head should, in great part,, if not
all be excluded, especially those with truncate elytra (see remarks on
Basoh'a, etc., in Cratocerini). This tribe is represented in our fauna
by Morio monilicornis Latr., a shining black insect of moderate size,
resembling somewhat Pterostichus. It occurs in the Southern States
and is found under bark.

Tribe XXII.— Bembidiini.

Antennfe slender, arising under a slight frontal margin, tlie first two or often
the first only glabrous, third joint sometimes not longer than the seeond. Head
rarely narrowed behind the eyes to a neck ( Thafafisobius) , with two supra-orbital
setse. Eyes round prominent, very narrowly sejjarated beneath from the mouth
{ahsent in Anillus and Scotodipnus). Clypeus usually inoderateh' prolonged and
with an erect seta on each side. Labrum transverse, sexsetose in front, rarely
quite small (certain Bembidia). Mandibles feebly arcuate, acute at tip and with
a setigerous puncture externally. Maxillw slender, hooked lit tip, ciliate or slightly
spinulose within, the outer lobe slender and biarticulate or with the two joints
united (Amerizus), the palpi moderate in length, the last joint usually snuill,
subulate, sometimes conical, the penultimate club-shaped and pubescent. Mentuin
with basal suture distinct, variably emarginate, toothed, the tooth simple or
notched, the ligula broader in front, free and truncate at tip and bisetose, the setre
usually very closely approximated, the paraglossse slender, longer than the ligula
and not ciliate within, the palpi moderate in length, the terminal joint small,
subulate, the penultimate more or less club-shaped and bisetose in front. Thorax
with a setige'rous puncture at the side and at the hind angle. Elytra sometimes
margined at base, sides narrowly inflexed, the margin interrupted posteriorly and
with a distinct internal plica, disc with dorsal punctures or fovete. Prosternum
not prolonged. Mesosternum moderately separating the coxa;, the epimera moder-
ately broad and wider externally. Metasternal epimera distinct, posterior coxaj
contiguous. Legs moderate, the middle and posterior tibiae slightly ciliate exter-
nally, the anterior deeply emarginate within and sometimes with the outer apical
angle obliquely truncate '(certain Tachyti). Tarsi slender, claws simple, rarely
serrulate {Elaphropv.x). Surface usually glabrous, pubescent in ( Tachypus).

The males have usually two joints of the anterior tarsi dilated and squaniu-
lose or pilose (Tachypus) beneath, but in some Tachys the tarsi are simihir in
the sexes.

This tribe is about as well defined as any in the Carabidse, the form
of the hist joint of the palpi being peculiar to it and giving the name by
which it is often, known, Suhuliptdpi .

It is remarkable that, in a tribe so remote from Caliistun, the form
of the outer lobe of the maxilla in that genus should be here repeated.
It must however be especially remarked, that there is in Amerizva no

(29).

134 GEO. H. HORN, M. D.

such complete fusion of the two pieces as in Callistus where the suture
is not at all visible. In the former genus the suture is plainly evident
if the under side is examined and not visible on the upper as shown
in figure 38.

The serrate claws of Elaphropus Motsch., is a very singular cha-
racter to occur in the present tribe, that it does occur I have assured
myself by the examination of a specimen which I owe to the liberality
of Dr. Dohrn. The species of this genus resemble Tacliys and notably
incurvus, etc.

The genera known to occur in our fauna are as follows :

Anterior tibiae not obliquely truncate at apex. Sutural stria not recurved at apex.
Eyes large or moderate.

Elytra punctured without strise, surface finely pubescent Tachypus.

Elytra striate or striato-punctate, glabrous Bembidium.

Eyes entirely wanting Ailillus.

Anterior tibise obliquely truncate at apex. Sutural stria recurved at apex.

Elytra with the eighth stria interrupted or less deep at middle Tachys.

Elytra with the eighth stria very deep Pericompsiis.

With Bembidium I include Li/mnaeum and also for the present
Amerizus Chaud. (Rev. Mag. Zooh 1868). The latter genus was
founded on Trechus spectahilis Mann., from the peculiar structure of
the outer maxillary lobe. Beneath his generic description Chaudoir takes
occasion to refer Trechus ohlongulus Mann., to the genus Lymnseum,
as an aberrant species. On dissection I find the outer maxillaiy lobe
probably more completely consolidated than in the true Amerizus.
Rather than recognize a genus with two so dissimilar species I think
it better to ignore the character and refer both to Bembidium where
each will find better associates. It is well known that the mouth parts
in Bembidium vary otherwise to an extent which would be considered
generic in other parts of the series but all attempts to divide it have thus
far been unsuccessful, the characters becoming evanescent.

Tachypus is however capable of feeble definition but the general
appearance of the species is so distinct that it seems preferable to
retain it.

Tacliys and Pericompsus should probably be united the characters
separating the latter being rather those of a group of species than
a genus.

After placing at the head of the present series those tribes which
appear to link the aggregate Carabinge and Harpalinse, the present tribe
should then follow as that which most intimately connects a particular
tribe (Elaphrini), of the former with the latter. Next in order follow
naturally the Pogonini and Pterostichini.

AMERICAN COLEOPTERA. 135

Tribe XXIII.— Pogonini.

AntennfE slender arising under a feeble frontal ridge, the third joint usually
very little longer than the second, the first two joints only glabrous. Head some-
times constricted behind the eyes, two supra-orbital setse. Eyes (sometimes absent),
rarely prominent, distant beneath from the mouth. Clypeus moderately prolonged
and with a setigerous puncture each side. Labrum short, truncate or broadly
emarginate, plurisetose in front. Mandibles moderately prominent, feebly arcuate,
acute at tip and with a setigerous puncture on the outer side. Maxillse slender,
acute at tip, ciliate with a few stiff hairs inside, the outer lobe biarticulate, palpi
moderate or long, the terminal joint variable but hot subulate, the penultimate
joint not pubescent. Mentum broad, its basal suture often obsolete, deeply emar-
ginate and toothed, the tooth bifid or simple, the epilobes often dentiform, ligula
moderately prominent, usually broad the tip free and arcuate, uni- or bisetose
{Pogoni) or even plurisetose (Trechi), the paraglossije slender, very little longer
than the ligula and not ciliate within [Pogoni) or slender, long and ciliate within
at tip [Trechi), the palpi slightly variable the last joint not subulate. Thorax
with a seta at the sides and at hind angle. Body not pedunculaie, scutellum
distinct. Elytra sometimes margined at base, sides narrowly inflexed, margin
posteriorly entire or with a very feeble sinuation and without internal plica, disc
more or less striate, dorsal punctures distinct. Prosternum not prolonged at tip.
Mesosternum declivous in front, moderately separating the coxse, the epimera
narrow. Metasternum variable in length, the epimera distinct, the posterior coxae
contiguous. Legs moderate or slender, the tibiae not spinulose externally, the
anterior deeply emarginate within the inner spur remote from the apex. Tarsi
slender, claws simple.

The anterior tarsi of the males have two joints dilated and squamulose beneath.
As above constituted the tribe contains in our launa two <;roii])t^,
separated in the following manner :

Terminal joint of palpi more or less cylindrical and obtuse at tip, that of the

labial palpi as long as the preceding Pogoni.

Terminal joint of palpi slender, acute at tij), that of the labial pal])i shorter than

the preceding TiiKcni.

In addition to the above characters the form of the paraglossas
and the setae of the ligula add some weight to the separation of
the two groups.

The group Pogoni contains in our fauna two genera :

Head more or less constricted behind the eyes or transversely impressed. Elytra
not margined at base l*atrobus.

Head not constricted behind the eyes. Elytra usually margined at base.

I'OgOIIUM.

This group has been the subject of a special essay by Baron Chaudoir,
(Ann. Belg. xiv, pp. 21 — 61), in which he divides the species of the
former genus in our fauna into two genera Patrohus and P/(ttidius, and
the latter into Pogomis, Foyonistes and Diplochsefus. I have given
elsewhere a review of our genera and species in which will be found
my reasons for not adopting the genera suggested by Chaudoir, ( Trans.
Am. Ent. Soo. v. pp. 180 and 248).

136 GEO. H. HORN, M. D.

The group Trechi contains in our fiiuna two genera which have the
second joint of the antennae somewhat pubescent, they are as follows :

Head with distinct eyes. Anterior tibiae slightly broader to tip, the emargination

extending nearly to the middle of the tibia TreclillS.

Head without eyes. Anterior tibipe slender, the eniarginatioji at apical third.

Anophtlialmus.

Our species of the latter genus may be divided in two series, the first
contains Tellkampfii in which the last joint of the maxillary palpus is
very distinctly shorter than the penultimate, the second comprises all our
other species with the same joint equal to or even a little longer than
the preceding.

The tribe Pogonini of the present essay is about the same as that
intended by Lacordaire, (Glenera i, p. 364), less the genera which have
been properly removed by Schaum and others. The latter author
however, separates the two groups and places the Pogoni among the
Pterostichiui rendering that tribe heterogeneous and indefinable while
the Trechi are found near Bembidiini.

I believe that Lacordaire and LeConte are correct in approximating
the Pogoni and Trechi but I do not think the characters separating them
are of tribal value. That they should be placed near Bembidiini as these
authors have done seems to me proper while the relationship of the
Pogoni with Pterostichus is much less evident. The structure of the
ligula and paraglossae varies but little between the Pterostichiui, Patro-
bini and Bembidiini.

The suture between the mentum and its support is often entirely obliter-
ated especially in Anophthalmus, and is very indistinct in" some Patrohus
although sufficiently marked in others, and in nearly all Treclms.

To this tribe and closely related to the Trechi I would refer the*genus
Ooptems. Lacordaire places the genus in his Cnemacanthides, the
Broscides of other authors, but Putzeys in his monograph rejects it.
Guerin-Meneville in the origin placed it among the subulipalpi and was
more nearly correct than LaQordaire. Ooptertis has all the essential
characters of the group Trechi even to the impressed and recurrent
stria and it seems to indicate a strong attempt to unite the Pogonini
and Bembidiini.

Tribe XXIV.— Pterostichini.

AntennsD arising under a distinct frontal ridge, the th!'ee basal joints glabrous.
Head more or less constricted behind the eyes, except in Amara, and with two
supra-orbital setigerous punctures, clypeus prolonged beyond the base of the
mandibles, the latter without setigerous puncture externally. Maxillae ciliate or
spinulose' within, hooked at tip (except Stomis and Agelcea), the palpi of moder-
ate length and uf variable structure. Mentum broad, of variable length, usually

AMERICAN COLEOPTERA.

137

deeply emarginate and toothed, varying to a simple bisinuation ; ligula at least
moderate in size, often large, more or less free at tip and bisetose (quadrisetose in
Myas), the paraglossse slender and usually longer than it, sometimes much longer
{Stomis, Loxandrus), the palpi variable in form the second joint sometimes longer
than the terminal. Thorax with at least one setigerous puncture at the side and
one at the hind angle. Body not pedunculate, (subpedunculate in some Evarthrus),
scutellum distinct. Elytra narrowly inflexed, margin strongly interrupted pos-
teriorly and with a well marked internal plica, disc usually with dorsal punctures.
Prosternum not prolonged at tip, margined or not. Mesosternum oblique or vertical
in front, rather widely separating the coxse, the epimera narrow and often wider
internally than externally. Metasternum and side pieces variable in length, the
epimera always distinct, posterior coxa; contiguous. Middle and posterior tibise
variably spinulose externally, the anterior slightly so near the tip, the latter
broader at tip deeply emarginate within, the inner spur situated at the summit
of the ehiargination."

The anterior tarsi of the male have three joints rather broadly dilated and
squamulose beneath.

As here intended the tribe contains several groups which Lacordaire
places in a higher rank. Schaum (Berl. Zeitsehr. 18G0, p. 17l>)> extends
the limits of the tribe in such a manner that it would be impossible to
define it, as he includes the Platynini, Patrobiiii and the genus Aritarctia.
The former I have excluded from the structure of the elytra, the anterior
tibia? and the male tarsi, the Patrobini by the characters especially noted
in the table as well as the pubescence of the antenna? and mode of
dilatation of the male tarsi, while Antarctia belongs also near Platynus.
Schaum has already scattered Lacordaire's Fseudo-Feronides, and of
Section viii of the latter author (Genera i, p. 306), we have but two
tribes remaining Trigouotomidex and Feronidea, these with all that
remains of the dismembered Stomides constitute the tribe of the present
essay which may be divided into three groups.*
Mentum feebly emarginate, sometimes simply bisinuate. the maxilLip hooked

at tip TiufiONOToiM:.

Mentum emarginate and toothed.

Maxillffi hooked at tip Pterostichi.

Maxilla; not hooked at tip Stomks.

Chaudoir has already indicated (Bull. Mosc. 1872), some changes in
the composition of the first group, the second is the only one represented
in our fauna and the third contains as far as I know but two genera,
Stomis and Age/sea. From the Pterostichi (Feronides Lac), in addition
to the eliminations already made I would exclude Zahrus which is by
far more closely to the Harpalinae than to the present tribe although
through it and Amara the relationship is approximated.

« From the characters given of the tribe Drimostomides by Chaudoir, (Ann.
Belg. xv), it seems probable that it might form a fourth group of the present tribe.

TRANS. AM. ENT. SOC. IX. (.30) SK I'TEMBKn. 1881.

138 GEO. H. HORN, M. D.

Among the genera of the first group Lacordaire places Amhlytelus
Erichs. After a careful examination of the species on which it is
founded I believe that author to be entirely correct. It is however an
exception in the entire tribe, as far as I know, in having the fourth tarsal
joint bilobed on all the feet. The general appearance of the species is
rather that of a Callidide but the entire elytra with the well marked
internal plica indicate the correctness of its reference here. The group
Trigonotomae seems however rather unnatural and should in all probability
be separated. Amhlytelus will in any event represent a distinct group.

The group Pterostichi is the only one represented in our fauna and
the number of the genera must remain the subject of discussion until
a thorough monograph shall have fixed their limits. Those of our own
fauna require discussion here.

In order that the reader may have some point of departure from
which to follow the argument I reproduce the table of genera given
by Dr. LeConte in his last discussion of the subject, (Proc. Acad. 1873,
p. 302), to which I add Myas and Amara.

Last joint of palpi dilated. Mentum tooth obtuse Myas.

Last joint of palpi cylindrical or slightly oval.

Mandibles striate; elytra with one dorsal puncture Evarthrus.

Mandibles not striate.
Mentum tooth emarginate.
Ligula carinate.

Metathoracic episterna long Lophoglossus.

Metathoracic episterna short Holciophorus.

Ligula not carinate.

Front tarsi of %, normally dilated.

Second joint of labial palpi bisetose Pterostichus.

Second joint plurisetose Amara.

Front tarsi of %, obliquely dilated Loxandrus.

Mentum tooth entire Piesmus.

In Myas the characters are undoubtedly valid and in addition it might
be added that the ligula is quadrisetose in front, a character figured by
Migneaux but not mentioned by Duval. The elytra have no dorsal
puncture and the mandibles are obliquely striate.

The striation of the mandibles which seems to have been a character of
last resort in the separation of Evarthrus will not by any means hold
good with many species of Pterostichus, {rostratus, tumescens, mancus,
coracinus, etc.), which have the mandibles more deeply striate than very
many Evarthrus.

The species of Evarthrus are readily separable into two series, the
first has the penultimate joint of the labial palpi longer than the last
and with three or four long setae, the second has the terminal joint

AMERICAN COLEOPTERA. 139

longer and the penultimate merely bisetose, the mandibles are decidedly
sulcate in the first series (species 1 — 12), and often very feebly so in
the second, (species 13 — 25, Synopsis loc. cit.).

The carination of the ligula has no value as a generic character, in
fact the carinate ligula occurs in many places in Pterostichus, (varying in
degree), especially in the flatter species from the Pacific region.

The manner of the dilatation of the tarsi in Loxandrus serves to
separate it sufficiently in a group where the characters are so feeble.

The plurisetose second joint of the labial palpi, and its consequently
greater length than the third, serves to separajte Amara from all the
other genera except the first or genuine series of Evarthrus.

The mentum tooth seems also to have lost value as many Pterostichus in
Europe have an obtuse tooth as in our submarginatus, while it appears to
have escaped notice that P. honestus Say, has a rather long acute tooth.

While retaining M^as and Loxandrus as distinct on characters which
are undoubtedly valid the other genera require some modification.

The following table represents the conclusions which I have arrived at ;

Terminal joint of palpi dilated. Elytra without dorsal puncture Mjas.

Terminal joint of palpi cylindrical or slightly oval.
Anterior tarsi of male normally dilated.

Terminal joint of palpi as long as or longer than the penultimate, the latter

bisetose in front Pteroslichiis.

Terminal joint of paljii shorter than the penultimate, the latter ))Iurisetose
in front.

Elytra with ©ne dorsal puncture Evarflirus.

Elytra without dorsal puncture Amara.

Anterior tarsi of male obliquely dilated liOxaiidnis.

By this arrangement Holciophorus, Lophoglossus, Piesmus and the
second series of Evarthrus revert to Pterostichus. Amara is intended
in its most comprehensive sense although some of its groups have
characters of apparently greater value than those used above in the
separation of genera. Loxandrus is the nearest approach in our fauna
to the Trigonotomi».

Tribe XXV.— Licinini.

Antennae slender, moderately long, arising under a distinct frontal plate, the
three basal joints glabrous (two in Badister). Head short, moderately stout, witli
two supra-orbital setse, clypeus short not prolonged between the mandibles, emar-
ginate and exposing the basal membrane of the labrum, with a setigerous ptine-
ture in each angle. Labrum usually short, emarginate, longitudinally impressed.
Eyes moderate in size not very distant from the mouth except in Diccelus where
they are small and very distant. Mandibles stout more or less arcuate, tips usually
obtuse except in Diccehis where they are feebly arcuate and acute. Maxillse hooked
at tip ciliate within, the outer lobe rather slender, biarticulate, the palpi moderate
in length, the last joint variable in form. Mentum deeply emarginate without

140 GEO. H. HORN, M. D.

tooth (in our genera), the ligula and paraglossse variable in form, the former
bisetose at tip, the palpi moderate, the last joint variable in form but equal in
length to the preceding which is bisetose in front. Thorax variable in form, with
one (rarely two) lateral setigerous punctures and one near (rarely at) the hind
angle. Body not pedunculate. Elytra margined at base, sides at most moderately
inflexed the margin rarely {Licinus) sinuate, not interrupted and without internal
plica, surface striate and with one {Diplochila) two (Badister) or no dorsal punc-
ture (Diccelus). Prosternum obtuse at tip. Mesosternum concave in front, the
epimera very narrow. Metasternal epimera distinct. Posterior eoxse contiguous.
Anterior tibiae deeply emarginate within, the middle and posterior tibise slightly
spinulose or ciliate externally. Tarsi slender, claws simple.

The anterior tarsi of the males have three joints rather broadly dilated, densely
spongy pubescent and ciliate at the sides. In Licinus however there are but two
dilated joints.

This tribe contains but few genera and all authors seem pretty well
in accord as to its composition and it is a surprising thing to find
Ambli/stomus placed here by Bedel, (Ann. Fr. 1879, Suppl. p. 58),
a genus whose affinities ai-e so plainly with the Harpalini.

The affinities of the tribe are not well marked. The form of the head
recalls some Harpalini, Diplochila resembles superficially Microcephalus
of the Pterostichini, while Dicsehis has some analogy with Be/ecinm.

The genera proper to our fauna are three in number, Licinus silplioides
has in one or two instances been found but under circumstances which
induce me to believe that it had been introduced, for convenience how-
ever I add it to the table.

Antennae with three basal joints entirely glabrous.

Eighth and ninth striae of elytra very closely approximated. The third interval

with a dorsal puncture, apex very feebly sinuate Diplochila.

Eighth and ninth striae distant.
Elytra not sinuate at apex.

Seventh interval more or less carinate at base Dicselus.

Elytra strongly sinuate at apex.

Seventh interval not carinate Liiciiius.

Antenna? with two basal joints only glabrous. Eighth and ninth striae not
approximated, third interval with two dorsal punctures, apex not sinu-
ate Badister.

Diplochila has the terminal joint of the palpi more or less cylindrical
and obtuse at tip. Dicselus and Licinus have the last joint more or less
triangular and in Badister somewhat oval and flattened.

To this tribe should be referred the Australian genus Dicrochile. Its
front closely reproduces that of our Diplochila while the bifid labrum
is the legitimate development of the latter genus. The tarsi of the
male are moreover similarly dilated while the general ' aspect of the
species before me {D. Goryi Bdv.), is that of an elongate Badister.
Dicrochile has the tip of the mandibles emarginate.

AMERICAN COLEOPTERA. 141

Tribe XXVL— Platynini.

AntennEe slender rarely (Perigona) slightly thickened, arising below a slight
frontal ridge, the condyle exposed, three basal joints glabrous, first joint not long,
second usually short rarely as long as the third in which case neither is elongate,
third moderate in length usually longer than the others, but rarely equal to or
shorter than the fourth. Eyes moderately prominent, close to the mouth beneath.
Head oval, rarely elongate, eyes not very distant from the thorax, two supra-orbital
setse, front slightly narrowed before the eyes, clypeus moderately prolonged and
with a setigerous puncture each side. Labrum moderately prominent usually
truncate in front and sexsetose, rarely deeply emarginate. Mandibles moderately
prominent, feebly arcuate, acute at tip, without external seta. Maxillae hooked
at tip, ciliate or spinulose within, outer lobe biartieulate, palpi moderate in length,
the terminal joint variable, rarely securiform. Mentum deeply emarginate, toothed
or not, basal membrane more or less prominent, ligula very variable in form,
bisetose in front, the paraglossse variable in form and extent of union with the
ligular, palpi moderate, the last joint somewhat variable in form, the penultimate
bisetose in front. Thorax variable, sides with a setigerous puncture, a second at
the hind angle when the latter is distinct or in front of the angle when it is obtuse
or rounded. Elytra margined at base, sides narrowly inflexed, margin entire
without internal plica, apex obliquely sinuate, sometimes deeply, or even barely
perceptibly, dorsal punctures usually present, rarely {Pristovychus) wanting,
surface striate, the eighth stria distant from the margin except, in Perigona.
Prosternum not prolonged at tip. Mesosternal epimera narrow. Metasternal
epimera distinct, posterior coxse contiguous. Legs slender, the femora sometimes
thickened, tibise slender, not sulcate externally, the middle and posterior slightly
ciliate externally, the anterior slender emarginate within, spurs moderate in
length. Tarsi slender, the joints often sulcate on their outer side the fourth entire,
emarginate or bilobed. Claws simple, finely serrate or pectinate.

The males have the anterior tarsi with three joints feebly dilated and squamu-
lose beneath.

The tribe as here intended is the equivalent of Lacordaire's Aneho-
menides from which however some genera have been removed, Loxo-
crepis and Monolohus to the Carabinae, Oxyglossus and Stcnognathus
to the Lebiini.

As a part of the tribe, constitutintr probably a distinct group I would
suggest the addition of Antnrctia and Geohsenus and I entirely agree
with C. G. Thomson in adding Masoreim. I can not understand why
Chaudoir (Bull. Mosc. 1870), associates in a complex, (it can not be
called a tribe) Masoreus, the Tetragonoderides, Nemotarsus and the
Sarothrocrepides.

Perigona seems also better placed here than elsewhere and appears to
be a lead towards the Trechini in the same manner that Olisthopus does
to the Lebiini.

A study of the form of the ligula and paraglossae of those genera
which are acknowledged on all sides to be undoubted members of the
present tribe Flafynui^^ Calathm^ and Olhtliopus, seems to nie to show

142 GEO. H. HORN, M. D.

what little value these organs have in the formation of tribes and groups
of genera. The ligula of OHsthopus is very plainly that of many Lebiides,
Platijnus reproduces very closely that of Pterosticlius, Calathus proper
is as nearly as possible intermediate between the two while the section
Pristodactt/la is a modification of Flatynus. The tip of the ligula is free
in Platynus and Pristodactyla and not free in the other genera.

The mentum tooth also seems to furnish characters of an evanescent
nature. In some Platynus^ especially those in which the hind angles of
the thorax are distinct {brunneomarginatus, ovipennis, etc.), the tooth
is longitudinally impressed and emarginate at tip, while in the Ayonum
type the tooth is very obtuse. The same variation is observed in Calathus,
some having quite an acute tooth, others even bifid.

The tribe seems to be divisible primarily into three groups by the
following characters :

Eighth elytral stria distant from the margin and not deeply impressed.

Thorax truncate or emarginate at base Platyni.

Thorax slightly lobed at middle of base Masoref.

Eighth elytral stria confluent with the margin in its basal half, deeply impressed
and attaiiiing the suture Perigoni.

Group Platyni.
This group might easily be separated in many minor subdivisions by
including the genera not represented in our fauna.
The following genera occur with us :

Ungues more or less serrate. Mentum toothed.

Tarsi glabrous above. Elytra with dorsal punctures Calatliiis.

Tarsi hairy above. Elytra without dorsal punctures Pristonycliiis.

Ungues not serrate. Elytra with dorsal punctures.

Mentum toothed Platynus.

Mentum not toothed Olistliopus.

OHsthopus is represented in the Atlantic region by two species, the
other genera occur on both sides of the continent. Of Pristom/chus
two species are known both of them identical with European forms
(complunatus and terricola), and have probably been introduced, the first
mentioned being rather widely spread by commerce over the globe.

Anchus Lee, founded on Plutynus pusillus is not distinct from Platy-
nus. The species is our equivalent for Anchomenus ohlongulus Fab.,
of Europe, and may even be specifically identical, the only striking diflfer-
ence between the two being in the slightly wider thorax of our species.

To this group I would refer Wollaston's genus Zargm. The facies
of the species is not unlike that of certain of our Platynvs {stria tits,
snJcatus). The clypeus is membranous at middle even to a greater
extent than in DIcrochik while the labrum is also bifid. Chaudoir is

AMERICAN COLEOPTERA. 143

willing to believe Zurgus allied to DicrochlJe evidently from the form
of labrum, but it is really a true Plafynus form allied to Olisthopiis the
ligular characters of which it exaggerates.

Lestignuthus is also a member of the group. The description of the
ligula heretofore given is certainly very erroneous. The ligula is in
great part membranous with merely a small urn-shaped piece at the tip
corneous, the paraglossae are very distinct and longer than the ligula.
By comparing the figure which I give of the parts it will be observed
that the ligula does not differ essentially from Plafi/vus. The tip of
the ligula is connected with the paraglossae by a very thin transparent
membrane.

In the species of Lesfignathus before me I observe that the suture
between the mentum and its support is as completely obliterated as in
Enceladus. It is the only instance known to me of this character in
the present or the preceding tribe.

For the opportunity of examining Zargus Schaumii Woll., and
Lestignathus Simsonii. Bates, I am indebted to Mr. E. W. Janson.

Group Masorei.
No representative of this group occurs in our fauna. The latest
revision of the genera is by Chaudoir, (Bull. Mosc. 1876), in which
contrary to his usual custom he says but little of the parts of the mouth.
The fullest accounts of these are by Lacordaire and Duval, and both are
inaccurate in the description of the ligula and paraglossae. In Masoretis
Wetterhalli the ligula is triangular, truncate in front, the paraglossae
rather broad and not connate with the ligula to the tip but folded behind
it as represented in the accompanying dissection. It is evident that
Lacordaire and Duval have either dissected a Perigona or that the latter
author copied from the former who considered Perigona a synonym of
Masoreus. In his tribe of Masoreides Chaudoir places seven genera
some of which seem to me to belong to the next group.

Group PerigonjK.

This group is represented by one genus Perigona which has for its
synonyms Trechicus, Nestra and Spathinus. The mentum has its epi-
lobes prolonged to an acute spine, the emargination is deep without tooth.
The ligula is narrow and truncate at tip, the paraglossae slender and
a little longer than the ligula, and united with the latter by a thin
almost transparent membrane which extends from the base of the
paraglossae to the tip of the ligula.

The antennae are rather stout beyond the third joint and the second
is as Ions as the third.

144 GEO. H. HORN, M. D.

There is certainly no reason why Perigona, should be placed as a
Truncatipenne. The two supra-orbital setae remove it from association
with the Harpalide series. Taking its entire organization it seems better
placed in the present tribe than anywhere else.

Tribe XXVII.— Anchbnoderini.
Head oval or rounded, not prolonged nor constricted to a narrow neck; with
two supra-orbital setigerous punctures. Antennse slender, not thicker externally.
Eyes variable in prominence but always close to the buccal fissure beneath.
Thorax more or less cordiform the lateral margin distinct, setigerous punctures at
side striated the one in front of middle the second at the hind angle (except in
Lachnophorus where it is slightly in front). Elytra feebly margined at base, the
lateral margin distinct, apices rounded. Scutellum and scutellar stria distinct.
Tarsi slender, fourth joint simple. Claws simple. Posterior coxae contiguous.
Body above pubescent or pilose.

In the above characters will be found all that will define the genera
placed here. With other genera the tribe might possibly be more
properly divided in three but for the present they will be considered
groups forming an osculant tribe.

These groups are as follows :

Antennse with four glabrous joints.

Thorax ovate, lateral margin obtuse, the posterior setigerous puncture in front

of the basal angle. Body subpedunculate Lachnophori.

Last joint of palpi ovoid, suddenly acuminate at tip, the surface pubescent.

Elytra with three dorsal punctures Liacliuoplioriis^

Last joint of palpi conical, gradually narrowed to tip, the surface glabrous.

Elytra without dorsal punctures Euphorticus.

Thorax cordiform, lateral margin acute, the posterior setigerous puncture at the

hind angle. Body not pedunculate Anciionoderi.

Last joint of palpi gradually narrowed to tip and slightly oval. Elytra with

three feeble dorsal punctures Ancliouoderiis.

Antennse with three basal joints glabrous. Thorax cordate margin acute, the

hind angle with Setigerous puncture Atrani.

Palpi as in Anchonoderus. Dorsal punctures not evident Atranus.

The structure of the antennae of the first two tribes seems to have
been overlooked. The joints 2—4 are not absolutely glabrous in the
strict acceptation of the term but they are devoid of the fine punctuation
and pubescence which covers the following joints.

From the characters above given it will be evident that the Lachno-
phori osculate closely with the Egini and the Atrani with the Platynini.
while the Anchonoderi are intermediate between the other two groups.

Group Lachnophori.
Eyes large moderately prominent. Head oval, sometimes slightly
constricted behind the eyes, front more or less deflexed. Elytra not
margined at base, the apex with very feeble sinuation in Lachnophorus

AMERICAN COLEOPTERA. 145

or rounded in Euphorticus, the striae entire, the eighth stria distant from
the margin with very distinct ocellate punctures in the former genus, not
distinct in the latter. The setigerous punctures of the side of the thorax
are two in number, the first situated at the point of greatest width, the
second midway between this and the hind angle. The thorax is not
wider than the head between the eyes.

The males have the anterior tarsi slightly dilated and from the
anterior angle at the inner side of the joints 1 — 3 proceeds a brush
of fine silken hair.

To the two genera above named it will probably be necessary to add
Lasiocera. Euphorticus n. g. is founded on Lachn. jmhescenx Dej., and
the only characters separating it are those given in the table.

•Group Anchosoderi.

The eyes are not prominent. Head oval slightly narrowed behind
the eyes, front horizontal. Elytra not margined at base, the apices
rounded, surface striate, eighth stria distant from the margin and with the
ocellate punctures feeble, dorsal punctures three but fine and indistinct.
Thorax cordate as wide as the head, lateral setigerous punctures situated
at the point of greatest width and in the hind angle.

The anterior tarsi of the males have three joints slightly dilated and
with squamiform papillae and ciliate at the side.

Anchonoderus and probably Camptofoma enter this group. The former
genus alone is represented in our fauna by one species from Texas.

Group Atrani.

Head oval, more elongate than AnihonoderuR the eyes not prominent.
Antennae with but three joints glabrous, the fourth punctured and
pubescent as the fifth. Thorax cordate, a little broader than the head,
the setae in the normal position at the side and in the hind angles.
Elytra margined at base, the apices rounded, surface striate, the ocellate
punctures well marked, dorsal punctures not distinct.

The sexual characters are as in Anchonoderus.

This group contains in our fauna but one genus Atranns Lee. The
species A. puhescens Dej., was originally described as an Anchomenus ;
separated by LeConte with its present generic name it was placed among
the Chlaeniini. Chaudoir first suggested its removal from that position
to that in which it is now found.

Tribe XXVIII.- Ctenodactylini.

Antennffi slender, base free, three basal joints glabrous, first joint stouter, as
long as the next two, ,S— 11 equal or nearly so. Head rhomboidal, prolonged
behind the eyes and narrowed to a distinct neck, front with two supra-orbital
setse; clypeus moderately prolonged, a setigerous puncture each side. Eyes large

14(j GEO. H. HORN, M. D.

moderately prominent, narrowly separated from the mouth beneath. Labrum
transverse, feebly emarginate, margin sexsetose. Mandibles arcuate acute at tip,
not prominent. Maxillse slender, ciliate and spinous within, the outer lobe slender
and with two equal joints, the palpi slender, the terminal joint elongate-oval and
acute. , Mentum deeply emarginate, toothed, (except in Pionycha), ligula moder-
ately prominent, the tip bilobed or narrowed and bisetose, paraglossse slender
and acute usually longer than the ligula, palpi slender, last joint oval acute, the'
penultimate bisetose in front. Thorax elongate, narrower thfVn the head, margin
feeble, sides with a setigerous puncture near the middle and at the hind angle.
Body subpedunculate, scutellum not prolonged between the elytra. Elytra oblong-
oval, not margined at base, lateral margin distinct and entire, without internal
plica, apices rounded without sinuation, disc striate, third interval with three
indistinct dorsal punctures. Prosternum slightly prolonged at tip. Mesosternum
oblique, the epimera very narrow. Metasternal epimera distinct, posterior coxae
contiguous. Legs slender, middle and posterior tibife slightly ciliate externally,
the anterior emarginate, its spurs very small. Tarsi slender, the first joint as long
as the next two which are oval, the fourth broad, deeply bilobed and j^apillose
beneath, claws pimple dentate or pectinate.

The tarsi are alike in the sexes. The males have one seta on each side of the
apex of the last ventral segment, the females two.

The tribe as here constituted contains not only the Ctenodactylides of
Lacordaire but also his Trigonodactylides.

Two groups may be indicated.
Thorax narrow, elongate. Ligula slender usually narrowed in front.

CTENODACTyL.JE.

Thorax nearly or fully as wide as long. Ligula bilobed at tip HexagonijE.

The Ctenodactyl/E alone are represented in our fauna by Lepto-
trachehhs which occurs in the Atlantic region.

Regarding the Hexagon:^ as typified by Hexagonia (= Trigono-
dactyla) the only genus known, it can only be said that it is remarkable
that such an extraordinary error should have been allowed to pass current
from one author to another as has been done in the description of the
maxilla. After having carefully dissected the mouth of Trigonodactyta
the parts were placed under the microscope and an appearance of the
tip of the maxilla seemed to indicate that it was really terminated by
a moveable hook. 3Iy custom however has been in doubtful cases to
surround the parts with a drop of water on glass when all sutures and
other lines become apparent. Without wishing to describe in detail the
structure of the maxilla the reader is referred to the figure.

It will be observed in the two groups above indicated that the paraglossae
arise apparently by their base from the side of the ligula in the Cteno-
dactyli, but are prolonged to the base of the ligula in the Trigonodactyli.
The difference is however more apparent than real. If the ligula bo
observed from the inner side the paraglossae will be found adherent to
that side, their outer edge being very close to that of the ligula itself.

AMERICAN COLEOPTERA. I'AT

The tribe has affinities in two directions, the first group with the
Odacanthini, the second with the Dryptini. Schaum (Ins. Deutschl. i,
p. 251), places the. genera of the present tribe in his group Odacanthidfe
which inchides also the Odacanthini and Anchonoderini of the present

essay.

Tribe XXIX.— Odacanthini.
Antennfe slender, free at base, first joint as long as the next two, three basal
joints glabrous. Head oval more or less elongate, prolonged behind the eyes and
narrowed to a neck, two supra-orbital setse, elypeus moderately prolonged, trun-
cate, a setigerous puncture on each side. Eyes large moderately prominent, very
narrowly separated from the mouth beneath. Labrum moderately prominent,
sexsetose in front. Maxillse slender, ciliate and spinous within, outer lobe biarticu-
late with equal joints, palpi slender, the last two joints nearly equal the terminal
slightly fusiform, acute at tip. Mentum emarginate and toothed, ligula usually
truncate at tip and bisetose, the apex free for a short distance, the paraglossfe small
rarely longer than it, the palpi slender the last joint slightly fusiform acute at
tip, the penultimate not longer than it and bi- rarely trisetose ir^ front. Thorax
narrow, the margin usually feeble or even entirely obliterated, a seta near the
middle of the side, a second at the hind angle which is often feeble. Body sub-
pedunculate, scutellum not projecting between the elytra. Elytra oblong-oval,
base not margined, sides narrowly inflexed, margin entire without internal plica,
the apices truncate, sometimes rather obliquely. 'Prosternum not prolonged.
Mesosternum oblique the epimera very narrow. Metasternal epimera distinct,
posterior coxa; contiguous. Legs slender, the middle and posterior tibia; slightly
ciliate externally, the anterior emarginate within, the spurs small. Tarsi usually
slender rarely flattened, the fourth joint at most feebly emarginate. Claws simple.
The anterior tarsi exhibit no ditierences in the two sexes.
In all the genera there will be observed numerous punctures, bearing
short erect hairs, situated either in the second stria or the third interval.
The tribe as here constituted js the same as in Lacordaire except that
Stenochila is excluded and Calophsena added. There is a close rela-
tionship between this tribe and the Ctenodaetylini, and they are united
by some authors, the only difference of moment being that the elytra are
here truncate and there entire.

With the Lebiini and Dryptini there is also a very close relationship,
the characters separating the present tribe from the former are certainly
not very well marked if we admit the Lacordairean aggregation. The
Lebiini of the present essay is composed of the Lebiides of Lacordaire
excluding especially Agra, the Pericalides and Mormolyce. Two of these
"•enera have an elono;ated head and thorax and all have truncate elytra.

I can find no constant character separating the Odacanthini from the
Dryptini. excepting in the form of the labial palpi. For this reason
I remove Stenochila which' has not only the long joint of the antennae
but also the penultimate joint of the labial palpi plurisetose. Calophsena
however has the palpi and antennae of the present tribe.

148 GEO. H. HORN, M. D.

The only genus which occurs in our fauna is Casnonia represented
by two species pensylvanica and ludoviciana, in which the setigerous
punctures of the second stria are very indistinct and rarely more than
four in number. The last mentioned species is remarkable in having
the thoracic margin rounded and the sutures of the under side entirely
obliterated. The only other instance known to me of such a structure
is in Apotomus, which Schaum says is distinguished from all other
Carabidae in this manner.

Tribe XXX.— Dryptini.

Antennae setaceous, free at base, three basal joints somewhat less pubescent,
the first usually elongate and thicker than the following. Head constricted at
a variable distance behind the eyes to a neck which sometimes expands semi-
globularly at its insertion in the thorax, front narrowed before the eyes, two
supra-orbital setse, clypeus moderately prolonged and with a variable number
of setigerous punctures, sometimes (Drypta) without any. Eyes oval moderately
prominent, usually not very close to the mouth beneath. Labrum transverse,
moderately prominent, truncate or feebly emarginate, sexsetose in front, the two
lateral setse in Drypta stouter, longer and nearly vertical. Mandibles slightly
prominent, feebly arcuate, acute at tip. Maxillae hooked at tip, ciliate or spinous
within, outer lobe usually slender, biarticulate, with equal lobes, palpi long, more
or less hirsute, the terminal joint more or less triangular. Mentum variable in
form, deeply emarginate with or without tooth, ligula and paraglossae variable in
form, the palpi moderately long, the terminal joint shorter than the preceding,
more or less triangular in form, the penultimate longer and plurisetose in front.
Thorax variable in form, often moderately long, the lateral margin acute, (except
in Drypta) the lateral setae often indistinct, that of the posterior angle usually
entirely absent. Scutellum distinct. Elytra not margined at base, lateral margin
acute, entire, apex truncate, dorsal punctures absent except in Stenochila. Pro-
sternum not prolonged. Mesosternal epimera very narrow. Metasternal epimera
distinct, posterior coxae contiguous. Legs moderately long, the femora often slightly
clavate, the middle and posterior tibiae ciliate or slightly spinous externally, the
anterior slender, deeply emarginate within, the tibial spurs moderate in length,
rarely ( Galerita) long. Tarsi variable in form, the claws simple or pectinate.

The males have the anterior tarsi dilated, sometimes very slightly and densely
juibescent beneath.

The tribe as here constituted is the equivalent of Lacordaire's Galeri-
tides, for which later authors have adopted the name which I retain.

I have already given in the Ctenodactylini the reasons for the change
of places of Stenochila and Caloplipemt. Poli/stichua is removed to
Ilelluonini for reasons which will hereafter be given. The essential
character separating the Dryptini from all other Truncatipennes is found
in the structure of the labial palpi. The form of the basal joint of the
antennae usually relied on is by no means a good character as several of
the preceding tribes have the first joint even longer than some of those
of the present. Where the scape attains its typical length it is usually

AMERICAN COLEOPTERA. 149

more or less curved near the base as in Agra. It is difficult in many of
the genera to say how many joints are truly pubescent as the hairs extend
nearly to the base of the first joint.

The head assumes three forms, the first is that typified by Galerita in
which the head is elongate-oval, considerably prolonged behind the eyes
then constricted to a very narrow neck which dilates to a semiglobular
condyle, the second is the Zuphium type where there is a moderate pro-
longation behind the eye and then very suddenly constricted to a narrow
neck which is cylindrical, while in Drypta the constriction is close to the
eyes, not abrupt and the neck rather stout and cylindrical. The latter
genus is further remarkable in having the setae of the clypeus entirely
wanting, their function being replaced by those of outer side of the
labrum which ac([uire an unuBual development, a similar occurrence has
been observed in Pelecium.

This tribe through Galerita and Stenochila shows a relationship well
marked with the Odacanthini, and by Thalpius to the Helluonini through
Folyatichus which must be placed in the latter tribe.

Our genera are not numerous and may be known by the characters
of the following table :

Neck very narrow.

Head prolonged behind the eyes, neck inserted in thorax by a semiglobular

condyle. Clypeus with two setigerous punctures each side Galerita.

Head triangular scarcely prolonged behind the eyes, very suddenly constricted
to a narrow cylindrical neck. Clypeus with but one setigerous puncture on

each side with a long seta Zii|> Ilium.

Neck stout, head very little constricted.

Thorax truncate at base, antennae with third joint shorter than the fourth.

Diapliurus.
Thorax subpedunculate at base, antennse with joints 2—4 nearly equal.

Thalpius.

The above genera are represented on both sides of the continent.

Tribe XXXI.— Mormolycini.

Antennse slender, nearly as long as the body, the base exposed, four basal joints
glabrous, the following densely punctured and very finely pubescent, first joint
elongate pyriform, second short, third as long as the head, fourth a little shorter,
5—11 much shorter, subequal. Head very long behind the eyes, forming a flat-
tened neck which is moderately constricted at base and expanded semiglobularly
at its insertion in the thorax, front with two small supra-orbital setae. Clypeus
moderately prolonged, feebly emarginate, a setigerous puncture each side. Eyes
round, moderately prominent, distant beneath from the buccal fissure. Labrum
nearly square, feebly emarginate and sexsetose in front. Mandibles stout, arcuate,
tip acute, a small tooth at middle on the right side, near apex on the left, outer
side concave at base, without setigerous puncture, upper side with a short but deep
cicatrix-like fissure at the end of the carina. Maxillae moderately short, hooked
at tip, inner edge densely ciliate, outer lobe slender, biarticulate, the palpi stout,

(33j

the terminal joint subeylindrical obtuse at tip. Mentum deeply emarginate and
with a slender acute tooth. Ligula slender acute and bisetose at tip, the paraglossse
broad, membranous, adhering to the ligula to the tip and prolonged beyond it but
not becoming united, the palpi stout, terminal joint suboylifidrical, obtuse at tip,
with short ciliae on its inner side, penultimate joint bisetose in front. Thorax
elongate the margin with a coarsely dentate expansion and without setigerous
punctures. Seutellum distinct. Elytra (less the expansion) oblong-oval, truncate
at tip, the sutural angle acute, base not margined, very narrowly embracing the
body, the margin acute and expanded in a foliaceous plate which is prolonged
beyond the apices of the elytra, surface striate, the third interval with three
dorsal punctures each situated in a small tubercle. Prosternum not prolonged,
the thoracic sutures obsolete. Mesosternum narrowly separating the coxse, the
epimera broad and attaining the coxse. Metasternal episterna also attaining the
middle coxse, the epimera distinct. Posterior coxse contiguous. Legs long and
slender, middle tibise ciliate near the tip, posterior tibiae not ciliate, anterior tibiae
emarginate within, the spurs on all the tibise ^mall. Tarsi similar in the sexes,
slender, the first joint as long as the next three and with short hairs beneath, the
other joints not ciliate. Claws simple.

This tribe is represented by the single genus Mormolyce containing
three species which occur in Java and adjacent regions. It is especially
remarkable in being the only exception, as far as I know, to the value of
the mesosternal epimeron in determining the position of a genus in the
Carabide series. In the preceding pages I have attempted to demonstrate
that Siagona and the Ozjenini have the mesosternum formed in the
manner normal to the present sub-family. It will also be observed by
the figure of the under side of Mormoltjce (PI. Ill, fig. 3), that the
metasternal episterna also reach the middle coxa3, a character entirely
without parallel in all the Carabidae although quite common in Dytiscidae
and present in Amphizoa.

The position of the genus after disregarding the anomalous sternal
structure is still open to discussion. The association of it with the
Feronides (Pterostichiui) by the older authors is now generally abandoned
and all seem to agree that it is a true Truncatipenne. Chaudoir (Bull.
Mosc. 1848, i, p. 123), indicated for it a position near Thyreopteriis an
opinion since repeated (Ann. Belg. xii, 1869, p. 133), but with Avhich
I can not agree. Even the most enthusiastic advocates of such an idea
must admit that it is about as unlike the other genera of the Thyre-
opterides of Chaudoir as it is unlike an ordinary Lebia.

Those whose range of study extends over the entire Coleoptera have
observed that genera occur in very many families in which the species,
by the enormous development of some members of the external portion
of the body, assume a form or appearance entirely concealing the true
relationship. Instances of mimicry are numerous but these are foreign
to the idea at present intended. ^

AMERICAN COLEOPTERA. ., 151

Mormolyce is in particular one of those genera with unusual develop-
ments. These are the margining of the thorax and the leaf-like expansion
of the eljtral margin. If we dismiss for a moment from our consideration
these appendages and allow Mormolyce to stand as if deprived of them
it becomes reduced to an insect not very diiFerent from an Odacanthide
or a Ctenodactylide.

The elongate head, with the extremity of the neck dilated in a semi-
globular manner, the narrow thorax, the elytra not margined at base,
the dorsal punctures all on the third interval, are characters which
cannot be neglected.

The ligula and paraglossae of Mormolyce are said to be as in the
Thyreopterides but from the descriptions these organs vary in that
group, and in the present genus I do not find as much resemblance
to Eurydera as to Coptodera serata (84).

I would suggest that Mormolyce be constituted a distinct tribe to be
placed in the vicinity of the Odacanthini and Ctenodactylini.

Tribe XXXII.— Agrini.
Antennae slender, moderately long, arising under a slight frontal plate, three
basal joints glabrous, first joint moderate in length, slightly arcuate near the base,
second short, third longer than the following which are subequal in length. Head
elongate, prolonged behind the eyes and suddenly constricted to a neck which
forms a seraiglobular condyle, front with two supra-orbital setse. Clypeus moder-
ately prolonged, a setigerous puncture each side. Eyes moderately prominent,
close to the mouth beneath. Labrum moderately prominent, nearly square or
slightlj' transverse, sexsetose in front. Mandibles slightly prominent, feebly
arcuate, acute at tip without setigerous puncture. Maxillse hooked at tip, with
very short cilise within, the outer lobe rather stout, biarticulate, the terminal joint
shorter, palpi stout not long, the terminal joint subcylindrical, longer than the
preceding and obtuse at tip. Mentum moderately emarginate with an obtuse
tooth sometimes nearly as long as the lateral lobes. Ligula coriaceous, more or
less rhomboidal, moderately prominent, quadrisetose, two setae at the tip and one
on each side posteriorly, paraglossee membranous, adherent to the ligula and not
longer, palpi longer than the nftixillaries, the terminal joint broadly securiform,
the penultimate bisetose in front. Thorax elongate conical, the lateral margin
almost obliterated, the lateral and angular setigerous punctures indistinct. Scutel-
lum distinct, feebly prolonged between the elytra. Elytra prolonged at base and
not margined there, sides narrowly inflexed, lateral margin entire, without internal
plica, the apex truncaite and often spinous or dentate, surface variably sculptured
but when striate the dorsal punctures are numerous and very evident on the
striae 2—4 — 6, the ninth stria close to the margin. Prosternum not prolonged.
Mesosternum oblique, the epimera very narrow. Metasternal epimera distinct,
posterior coxse contiguous. Legs moderate in length, femora, especially the ante-
rior, somewhat clavate, tibise slightly ciliate externally, the terminal spurs small,
anterior tibiae deeply emargiiiate within. Tarsi moderate in length, flattened on
all the feet, ciliate above, densely pubescent beneath and ciliate at the sides, fourth
joint deeply bilobed. Claws stout, pectinate in their entire length.

152 ^ GEO. H. HORN, M. D.

The anterior tarsi of the male are more dilated than in the female. The sexual
characters are otherwise variable and are found in the form of the middle and
posterior tibiae and the sculpture and pubescence of the abdomen.

In comparing the species of this tribe with those of the Odacanthini
and CtenodactyUni it will be seen that there is a close relationship which
can not be neglected for the structure of the ligula alone. By retaining
Agra in any part of the true Lebiide series we introduce confusion as
great as with Mormolyce. In many parts of the Carabide series the
ligula has been entirely neglected where its consideration would cause an
obvious violation of natural affinities. Conspicuous among these cases of
neglect we find the Cxraphipterini and Athiini.

It may be well to call attention to the fact that in all the tribes
with long head and thorax the tibial spurs are exceptionally small, and
Lacordaire says of Agra " sans epines terminales."

The species of this tribe belong to two genera, Agra and Agridia and
all with one exception occur in intertropical America.

Tribe XXXIII.— Egini.

Antennae moderate in length, slightly thicker externally, arising under a feeble
frontal ridge, the four basal joints glabrous, that is they are somewhat hairy but
not densely punctured and finely pubescent as the following joints, the basal joint
moderately stout but not equal in length to the two following joints together.
Head oval rather strongly constricted at a distance behind the eyes to a neck, with
two supra-orbital setae. Eyes oval in the axis of the head, moderately prominent
but distant beneath from the mouth. Clypeus feebly prolonged, a setigerous
puncture each side. Labrum feebly prominent, slightly emarginate, sexsetose.
Mandibles acute at tip, without setigerous puncture externally. Maxillse slender,
slightly hooked at tip, spinulose and ciliate internally, outer lobe slender, biarticu-
late, the terminal joint shorter, the palpi moderate in length, the terminal joint
obovoid, suddenly narrowed and prolonged at tip, surface pubescent. Mentum
deeply emarginate and with a short obtuse tooth; ligula not prominent, emar-
ginate and bisetose at apex, the tip free for a short distance, paraglossse slightly
longer than it, palpi moderate the terminal joint like that of the maxilla, the
penultimate bisetose in front. Thorax ovate, somewhat constricted at base, margin
almost entirely obliterated, sides with two setigerous punctures placed almost as
in the Clivince. Body distinctly pedunculate, scutellum not visible between the
elytra. Elytra not margined at base and without scutellar stria, lateral margin
obsolete, sides narrowly inflexed, apex subtruncate, disc striate at base, dorsal
punctures three but indistinct. Prosternum not prolonged. Mesosternum oblique,
the epimera very narrow. Metasternal epimera distinct, posterior coxae separated.
Legs slender, tibiae ciliate externally, the anterior deeply emarginate within.
Tarsi slender and long, fourth joint entire. Claws simple.

The anterior tarsi of the male are merely a little stouter than those of the
female and somewhat more ciliate.

I know of but one genus which enters this tribe, Ega. In the books
it forms a part of Lacordaire's tribe Anchonoderides and with Schaum
and LeConte of the more comprehensive tribe Odacanthini.

AMERICAN COLEOPTERA. • 153

The many peculiar characters which Ega possesses seem to me sufficient
to place it as a distinct tribe. In the present series the pedunculate
body is known to me as occurring only in the Anthiini and it is here too
that we have the posterior coxae separated and the eyes oval in the axis
of the head. It is by no means easy to determine the true thoracic
setigerous punctures as there are many short erect hairs, the true tactile
setas will be found remaining when the others are lost. The obliteration
of the side margin of the thorax is nearly as complete as in Apotnmus
while the absence of the lateral margin of the elytra is an important
character which appears to have been lost sight of.

The separation of the posterior coxas seems to me evidence of a
degraded or undeveloped type.

The relationship of the present tribe is undoubtedly with certain
members of the Anchonoderini while the relationship with the Anthiini
indicated above may be merely the possession of several characters in
common ; there may, however, be genera unknown to me wliich show
a true affinity between the two tribes.

Ega is represented in our fauna by two species, Sallei from the Gulf
States, Isetula from California. In the first the elytral grooves or striae
do not extend behind the middle and the three dorsal punctures are
faintly indicated ; in the second the striae extend at least two-thirds of
the elytra and I have been unable to detect any dorsal punctures.

Tribe XXXIV.-Lebiini.
Antennse slender, rarelj' slightly thickened, arising under a slight frontal ridge,
the condyle usually exjiosed, the three basal joints generally glabrous, sometimes
however, but two or four. Head oval, constricted to a neck or not, with two
supra-orbital setse, front either parallel or with convergent sides, clypeus with a
setigerous puncture each side. Eyes round or oval, moderately prominent very
narrowly separated from the mouth beneath. Labrum usually broader than long,
sometimes prolonged covering the mandibles, either truncate or emarginate and
sexsetose in front. Maxillfe slender hooked at tip, rather obtusely in Teiragono-
derus, ciliate or spinulose within rarely toothed behind the tip {Euccerus and
Teiragonoderus) the apex ciliate in many genera, outer lobe biarticulate but other-
wise variable, the palpi variable in form from slender to securiform. Mentum
more or less deeply emarginate, the epilobes always distinct, the bottom of the
emargination either without tooth or with a tooth of variable form ; ligula and
paraglossse very variable, the palpi also variable the terminal joint equal to the
preceding or longer, the latter bisetose in front (except in some Cymindis). Thorax
variable in form, sides distinctly margined and with a seta at the side and at the
basal angle. Elytra truncate at tip in a variable manner, the margin acute, entire
and narrowly inflexed, without internal plica, the base margined. Prosternum
usually obtuse at tip, rarely acute or prolonged {CydosomuH). Mesosternal epi-
mera narrow, sometimes almost entirely concealed by the episterna. Metasternal
epimera distinct, the posterior coxse contiguous. Legs usually slender, not very

IliAXS. AM. KNT. SOC. IX. (34) OCTOBER, 1881.

long, tiljise slender the terminal spurs moderate or short, rarely long {Tetragono-
derus, Nemotarsus), simple, rarely finely serrulate along their margins (Tetragono-
derus, etc.). Tarsi variable in form, the fourth joint narrow, emarginate, or deeply
hilobed, the claws usually pectinate or serrulate, sometimes however simple.

The sexual characters are variable. The anterior tarsi are often very nearly
equal in the sexes, sometimes with three or four joints slightly dilated in the male,
rarely the middle tarsi are dilated (Pinacodera). The anal segment has usually
more setse in the female than in the male.

The tribe as here intended is the equivalent of Lacordaire's Lebiides
and Pericalides omitting especially Agra and Mormo/j/ce.

After having given the tribe a careful -study, having purposely left it
for the final work in the present paper, I have found myself with the
same result as that arrived at by Lacordaire and LeConte, namely, that
it is not possible to divide the tribe in any satisfiictory manner. I have
dissected the mouth parts of all our own genera which are figured, with
many foreign to our fauna and the only conclusion I can arrive at, is,
that the ligula and paraglossae have very little value in defining groups
of genera. I can cite the two figures of the ligula of Valllda (93, 94),
in these the paraglossae are not united by a membrane which crosses the
front of the ligula, nor do we find it so in Dromius. In both of the
groups which Chaudoir bases on these two genera as types the paraglossae
should be united by a membrane crossing the front of the ligula.

The Lebiides of Baron Chaudoir are separated more especially by the
paraglossae pilose at tip and the intermediate tibiie of the male notched
within near the tip. The other characters given, occur, as every one will
see, in all parts of the Lebiide series. Other genera as in Dromius (86)
and Pinacodera (97) have the paraglossae ciliate at tip, while the male
of Coptodera a&rata has the middle tibiae incised as in Lehia. The
further division of the Lebiides into genera with and without epilobes
to the mentum is also misleading and I am quite prepared to state that
there is no Carabide without epilobes.

By these remarks I do not desire to discredit the work done by
Baron Chaudoir* who is acknowledged to be the ablest Carabologist of
the present time. The tribes and groups he indicates are composed of

* This and the preceding-pai'agrapjis may read strangely now that Chaudoir is
no more. They were written before his death and intended as full}' for his perusal
as for any one else. For many years Chaudoir has contributed valuable papers to
our knowledge of the Truncatipenne series, and as it has been found impossible to
present my own views without directly quoting him, I do not think that any
change of language, apparently less critical, would be of benefit in any respect.
I can only add that our relations, even with differences of opinion, have always
been of the most cordial nature, and were he living the remarks here presented
would be accepted in the spirit in which they are intended.

AMERICAN COLEOPTERA. 155

genera very closely and naturally allied, but the definition of these groups
is very artificial and we find already a great number of odd genera thrown
aside which will not fit in any tribe he has proposed and which must of
necessity form groups by themselves. Such a minute subdivision is con-
fusing but would be excusable and even acceptable if the characters on
which it is founded were even moderately constant, but with the few
genera which occur in our fauna I can say that no characters exist in the
ligula which can be used to divide the tribe into groups.

In the accompanying table the characters seem hardly to warrant any
further explanation. Attention might be directed to the very long tibial
spurs of Tetragonodeinis and Nemotarsus, in the former genus their edges
are finely serrulate a remarkable character in the present family and one
which is by no means common in Coleoptera generally.

In Fentagonica (Rhombodera) which in its form occupies an inter-
mediate position between Lehia (Aphelogenia) and Eucxrus the mandi-
bles are without scrobes, that is they are deprived of that triangular
groove on the outer side so commonly present in the Carabidae. The
mandibles here recall those of Loricera or Leistus although the lower
edge is less expanded than in these two genera.

To the present tribe and in close association with Tetragonoderia;, Chau-
doir has added C'^closomus a curious genus of a form and aspect closely
resembling Omophron, it is however correctly placed by that author.

Eucserus which will be found in one of the extremes of the following
table is one of those unfortunate genera which has never been allowed to
remain- for any length of time in any one position. At its beginning it
was placed «ear the Harpali, thence (Class. Col. N. A. p. 22), it was
removed and made part of a rather composite tribe and placed near the
Lachnophori. Chaudoir accepts this view. While it is doubtless an
o.sculaut form it seems to me more nearly allied to the present series
than to Lachnophorua.

The maxillae present a few variations from the usual fixed type and
attention is directed to the fignires of Tetragonoderus, Eucserus and
Pinacodera.

The antennae are very constant in their pubescence. In the vast
majority of species the three basal joints and the adjacent half of the
fourth are glabrous, but in Phloeoxena four joints are smooth while in
Eucserus the third is pubescent and the second scarcely less so.

The genera below are those known at present in our fauna. To have
introduced those exotic genera known to me would not have been a
difficult task, but it seemed to me to be unnecessary as very nearly if

15() GEO. H. HORN, M. D.

not quite all the subdivisions suggested by Chaudoir are represented by
genera around which the exotics may be grouped.

The following table will enable our genera to be recognized :

Tetragonoderus Dej. — This genus is made the type of a tribe by
Baron Chaudoir (Bull. Mosc. 1876), in which four other genera are
included, the essential characters being the form of the maxillae (80)
and the structure of the tibial spurs. The extremity of the inner lobe
of the maxilla is spoken of by Chaudoir rather as an appendix, but it
seems to be rather the true termination, the hook behind it corresponding
with the tooth which will be seen in the figure of Eucserus (100).
If we consider the tooth as the tip of the maxilla we have the anomaly
presented of the outer or palpar lobe longer than the inner, a character
not otherwise observed in the Carabidse.

Nemotarsus Lee. — This name has through the suggestion of some
extreme purists been lengthened to Nematotarsus without however adding
anything to a knowledge of the genus itself. This genus is placed by
Chaudoir in association with Tetragonoderus but not in the same tribe.
It is one of those genera which will fit in several tribes on a ligular
basis but will be excluded by characters which must be allowed to have
more weight.

Lebia Latr. — This genuS' has also been made the type of a tribe by
Chaudoir, to which he assigns characters by no means peculiar to the
genera included. Attention has already been partially directed to these
characters. In consequence of the existence of epilobes in the mentum
of all our species, it has. been found impossible to retain the divisions
suggested by Chaudoir. In the figures of the mentum Aphelogenia (83)
will be found to have epilobes but less developed than in Loxopeza (82).
The species occurring in our fauna are all referred to Lebia while the
divisions suggested by Chaudoir are rather groups of species than genera.

CoPTODERA Dej. — This is also the type of a tribe in the hands of
Baron Chaudoir, and that future students of our fauna may have the
special characters of the tribe at hand I reproduce them. (Ann. Belg.
xii, 1869) : " Ligula cornea, apice baud libera plerumque bisetosa, inter-
dum praeterea pluripilosa ; paraglossse, menibranaceae, apice pilosulae, aut
conniventes (ut in Coptodera) aut ligulam vix superantes. Csetera ut
in Thyreopteridisy

In what respect the Coptoderides differ from the Thyreopterides
I have not been able to realize even with patient study.

(35)

158 GEO. H. HORN, M. D.

Phlceoxena Chaud. — This genus is due to Chaudoir (Ann. Belg.
xii, 1869, p. 145), and is founded on species mostly Mexican with
which our Coptodera signata Dej., is associated. In his generic cha-
racters Chaudoir says : " Mentum * * * medio sinu dente majusculo,
trigono, apice rotundato," but I do not observe any tooth whatever in
our species.

This genus is part of the tribe Thyreopterides.

Dromius Bon., Apristus Chd., Blechrus Motsch., Metablettjs
Schmidt, and Axinopalpus Lee, have not, as far as I am aware, been
reviewed by Chaudoir, and are probably a part 'of his intended tribe
Dromiides which is merely casually mentioned in his preliminary remarks
on the Callidides, (Ann. Belg. xv, 1872). These genera may therefore
be passed without further remark than — that the ligula is not always bor-
dered in front by the extension of the paraglossae, not even in Dromius.
Certain European authors, among them Baron Chaudoir, have rejected
the name Axinopalpus for Variopalpus having been misled, evidently,
by the date given in the Munich Catalogue. The former genus was
published in 1846, the latter in 1848.

Tecnophilus Chaud., Bull. Mosc. 1877, i, p. 240. — This genus is
suggested for those species in our fauna formerly placed in Philotecnus
Mann., with which Chaudoir says they have nothing to do.

" Vu la configuration de sa languette que ses paraglosses ne bordent
pas anterieurement, ce genre ne fait pas partie du groupe des Callidides,
mais de celui des 31imodromiides dont je n'ai pas encore expose les
caracteres qui demandent a etre mieux etudies."

The ligula and paraglossfe reproduce exactly those of a species of
Gallida, as yet undescribed, which resembles umaragdina very closely
and differs from it in nearly the same manner that decora and punctata
do from each other.

Callida Dej., EuPROCTUS Sol., Plochionus Dej., form part of the
Callidides of Chaudoir, (Ann. Belg. xv, 1872), which has already been
sufficiently remarked upon. Several of our species of Callida have
been separated to form the genus Sponyoloba Chd., based on sexual
peculiarities of the male which seem to me to have had too great
value assigned them. Euproctus is represented in our fauna by one
species described as Onota trivittata Lee. (PI. IV, fig. 3).

Philophuga Motsch., contains those species formerly placed in
Glycia. They are reviewed by Chaudoir, (Bull. Mosc. 1877, i, p. 243),
who leaves us in doubt whether the genus is part of his Callidides or
not. They are not included in that essay.

AMERICAN COLEOPTERA. 159

Cymindis Latr., is the subject of an essay by Chaudoir, (Berl.
Zeitschr. 1873), and with three other genera constitutes the tribe Cymin-
dides, but I find that there are no special characters assigned to it.

PiNACODERA Schaum, and APENES Lee, are treated by Chaudoir in
a paper entitled, "Genres aberrants du groupe des Cymindides," (Bull.
Mosc. 1875), and as there are no characters assigned to the group it is im-
possible to ascertain in what respect these genera are especially aberrant.

Euc^RUS Lee, has already been referred to.

PentaCtOXICA Schmidt-Goebel, which has for its synonyms Didetus
Lee, and Rhomhndera Reiche, is the subject of a short essay by Chau-
doir, (Bull. Mosc. 1877, i, p. 212), who says that it is "one of those
aberrant genera which can not be made to enter any of the groups
established at the present time. I believe that jMr. Bates is correct in
placing it in a special group under the name Pentagonicinse," (Trans.
Ent. Soc. London, 1873, p. 320). This is certainly an easy settlement
of the difficulty, more particularly as no characters are assigned to
the group.

Corsyra. — This genus does not occur in our fauna. I merely
introduce it here to express a view that it has nothing to do with
Graphipterus as intimated by Chaudoir, (Bull. Mosc. 187G). The well
marked supra-orbital and thoracic setae, the structure of the labial palpi
and tibial spurs all forbid its position there.

Onota Chd., is represented by one species found in Florida:

O. Floridana n. sp.— Rufo-testaeeous, elytra brilliant green with extremely
narrow lateral and apical rufous border.. Antennae and palpi entirely pale. Front
with moderately deep arcuate groove within the insertion of the antennse, another
near the edge. Thorax as wide as the head including the eyes, as broad as long,
augulate in front of middle, the sides anteriorly feebly arcuate, posteriorly sinuate,
hind angles acute. Elytra moderately deeply striate, the striae finely punctured,
intervals slightly convex, smooth. Legs rufo-testaeeous. Length .20 — .25 inch ;
5—6.25 mm. PI. IV, fig. 4.

Three specimens without sexual difierences are before me, collected by
Hubbard and Schwarz, near Lake Poinsett, Florida.

It appears to resemble- 0. hicolor Chd., but is larger and the pale
border of the elytra is extremely narrow. Among our Lebiini it wUl
be at once known by the angulate sides of the thorax and distinct
hind angles.

A fuller description of tlie genus (which is placed by Chaudoir in
the Callidides), will be given in a future essay on the species of the
present tribe.

In concluding the Lebiini I regret to believe that the genera have
been inordinately multiplied, and the higher divisions whether called

160 GEO. H. HORN, M. D.

groups, tribes, or sub-families, have become so numerous and are based
on such shadowy characters as to envelope the subject in an almost
impenetrable cloud.

Tribe XXXV.-Helluonini.

Antennse moderate in length, rather stout, usually compressed arising under
a distinct frontal plate, all the joints more or less pubescent, two or four at the
base less densely, first joint stout, equal in length to the next two. Head broadly
oval, not narrowed in front of the eyes, with a distinct neck more or less abruptly
formed, clypeus moderately prolonged, a setigerous puncture at each side, front
with two supra-orbital setigerous punctures. Eyes round, moderately prominent,
close to the mouth beneath. Labrum usually large and prominent, more or less
concealing the mandibles, sexsetose in front. Mandibles stout, arcuate, rarely
prominent, acute at tip. Mentum broad, deeply emarginate usually toothed,
ligula prominent, bisetose at tip, the paraglossfe adherent to the sides rarely
[Polystichus) longer than it and usually semicorneous, the palpi of moderate
length, the terminal joint elongate-oval or fusiform and obtuse at tip, the penulti-
mate bisetose in front. Maxillae hooked at tip, ciliate or spinous within the outer
lobe rather stout, biartieulate, the palpi stout, the terminal joint oblong-oval
truncate at tip, more or less flattened. Thorax more or less cordate, sides and
hind angles with a distinct setigerous puncture. Elytra oblong, truncate at apex,
base not margined, sides narrowly infiexed, margin entire, disc striate or broadly
sulcate, without dorsal punctures. Prosternum not prolonged. Mesosternal epi-
mera narrow. Metasternal epimera distinct, the posterior coxse contiguous. Legs
moderate in length, the anterior femora more or less clavate. Tibife sometimes
(Helluomorpha) compressed and finely bicarinate on the outer edge, the anterior
rather stout and broad, deeply emarginate within, spurs moderate in length.
Tarsi moderate in length usually ciliate above, the fourth joint either entire,
emarginate or even bilobed. Claws simple.

The anterior tarsi of the male are rarely broader than the female.

This tribe is the equivalent of the Helluonides of Lacordaire, to which
I add PoJi/stichus.

The form of the ligula has been almost the entire reliance in the
separation of this tribe from the other Truncatipennes, but the method
usually adopted in describing the ligula as having no paraglossge is
entirely erroneous. Although the labium (which term includes the
entire organ, ligula and paraglossse), is almost entirely corneous in the
majority of genera, the parts which compose it are as evident as in A<jra
in which the whole organ is almost entirely membranous.

Polystichus is added from the Dryptini, as it lacks the palpar structure
which is characteristic of that tribe ; it has moreover the front parallel
before the eyes, forming a plate over the antennas, the anterior legs
rather stout and the antennas distinctly compressed. These latter are
decided characters approaching it to the present tribe. It is however one
of those forms which should be placed in the position of an intermediate.
Its ligula and paraglossfe are unlike the present tribe the paraglossae

AMERICAN COLEOPTERA. 161

being membranous, a little longer than the ligula, arcuate, obtuse and
finely ciliate. In the general form of body, especially the thorax,
Folystichus resembles very greatly Helluoviorpha.

The latter genus is the only one known to inhabit our fauna.

Helluodes Westw., placed by him in the present tribe does not belong
here, it is evidently allied to Anthia.

Tribe XXXVI.— Graphipterini.
Antennse more or less compressed, arising at a distance beneath a slight frontal
ridge, three basal joints glabrous, third joint eqnal in length or a little longer than
the next two together. Head with front deflexed, two supra-orbital setie, heck
stout, clypeus slightly prolonged, a setigerous puncture each side. Eyes oval in
the axis of the head, very distant beneath from the buccal iissure. Labrum
moderately prominent, arcuate in front but slightly emarginate at middle, sex-
setose.' Mandibles moderately stout, arcuate near the tip which is acute, inner
edge with slight tooth behind the middle, outer edge without setigerous puncture.
MaxilltB hooked at tip, coarsely and densely ciliate within, outer lobe biarticulate,
the terminal joint a little longer, palpi moderate in length the last two joints
nearly equal, the tenninal slightly oval and truncate at tip. Mentum deeply
emarginate, not toothed but with the bottom of the emargination slightly promi-
nent, ligula moderately prominent, elongate-oval, bisetose at tip, the paraglossse .
broad, membranous, adherent in tlieir entire length and meeting by a narrow
band at the apex of the ligula, palpi moderate in length, the terminal joint
cylindrical, arcuate, slightly stouter at middle, truncate at tip, shorter than the
preceding which is plurisetose in front. Thorax variable in form, cordate or
trapezoidal, margin acute, sides without setigerous punctures. Elytra not mar-
gined at base, broadly oval or suborbicular, feebly convex, apex truncate, margin
acute, no internal plica, the ocellate punctures of the margin indistinct (or entirely
wanting ?). Prosternum acute at tip, not prolonged. Mesosternum oblique, the
epipaera extremely narrower. Metasternal epimera distinct, posterior coxse con-
tiguous. Legs slender moderately long. Tibife with the outer edge sulcate in its
entire length and spinulose, the anterior emarginate within, the inner spur remote
from the apex. Posterior tibia? with the terminal spurs dissimilar, the inner very
slender, the outer cylindrical, compressed, and obliquely truncate at apex. Tarsi
slender with stiff bristles beneath, those at the tips of the joints long. Claws very
slender, simple. Body winged or not.

The males have three joints of the anterior tarsi slightly dilated with narmw
squamules beneath.

This tribe which is essentially African contains but two genera,
Graphipterus and Piezia. As Lacordaire correctly observes they are
in most respects Truncatipennes, but if the ligular characters were given
full power the two genera would be found in a very uncomfortable
position in the Lebiide series.

It will be observed that the setigerous punctures of the upper surface
are reduced almost to the mininuim and the supra-orbital seta3 are never
long, often inconspicuous. In quite a number of specimens which have
been examined no thoracic setoe have been observed.

1<»2 GEO. H. HORN, M. D.

The dissimilarity of the spurs of tlie hind tibia3 is a character which
I do not remember having observed elsewhere in the Carabidae.

The Graphipterini and Anthiini form together an isolated group of
genera with very little aflfinity with the other groups.

Tribe XXXVII.— Anthiini.
Anteniife moderately robust and long, the base free, three basal joints glabrous,
tiiird joint as long as the first. Head large sometimes slightly constricted behind
the eyes, the neck usually stout, two supra-orbital setigerous punctures. Eyes
moderately prominent, oval in the axis of the head, very distant beneath from
tlie mouth, the gente usually dilated. Clypeus moderately j)rolonged, truncate or
broadly emarginate, a setigerous puncture each side. Labrum large, prominent,
convex above* anterior jnargin with four or six setse. Mandibles usually variable
in the sexes, more elongate in the males, arcuate and acute at tip without setiger-
ous puncture on the outer side. Maxillae relatively slender, hooked at tip, densely
ciliate within, the outer lobe biarticulate, the terminal joint a little longer, the
palpi rather stout, the terminal joint slightly flattened, broader to tip and truncate.
Mentum very deeply emarginate without tooth, the palpi stout the terminal joint
much shorter and more slender than the second, this plurisetose in front, ligula
variable usually long and dilated in oval form witli three short setas on each side,
the paraglossse short and corneous. Thorax cordiform or somewhat hexagonal
and angulate at the sides with a setigerous puncture at the most prominent part
of the sides and none at the hind angle. Body subpedunculate, scutellum small.
Elytra not margined at base, sides narrowly inflexed, margin entire, no internal
plica, apices usually obliquely sinuate, the sutural angle often prominent. Pro-
sternum not prolonged. Mesosternum convex in front, the epimera very narrow.
Metasternal epimera distinct, posterior coxse usually separated, sometimes however
but narrowly. Legs moderately long. Tibiae very feebly spinous and not suleate
on the outer edge, the anterior moderately emarginate on the inner side, the inner
spur remote from the apex. Spurs of posterior tibise slender and similar. Tarsi
usually flattened, the first joint as long as the next three, the fourth more or less
emarginate, beneath spinous. Claws long, simple.

The males have three joints of the anterior tarsi moderately dilated and ciliate
and spinous beneath.

There are also sexual characters in the mandibles and the thorax is
often prolonged behind in two lobes in the males.

The ligula is described as having no paraglossa^, but this is certainly
incorrect and these members will be fovind by dissection as I have
figured them (105).

The genera of this tribe occur in xlfrica. They seem to bear
the same relation to the (rraphipterini that the Anchonoderini do to
the Lebiini.

Closely related to the present and preceding tribes are two genera
Helluodes and Pht/soa-ofaphus, which should probably form a distinct
tribe to be placed between the Anthiini and Graphipterini. Lacordaire
places the former genus in his Helluonides (ante p. IGO), the latter in
the Morionides (ante p. 133). T have studied Helluodes in nature and

had I sufficient details of the other genus would have defined the tribe
as indicated. The structure of the labial palpi is that of the present
tribe and the ligula of nearly the same type, the paraglossae are however
more developed.

Tribe XXXVIII.— Cratocerini.
Antennse shorter than the head and thorax, inserted under a sliglit frontal
ridge with however the condyle visible, three basal joints glabrous, 4 — 11 com-
pressed or somewhat moniliform. Head short, not narrowed behind to a neck,
clypeus slightly prolonged and without setigerous punctures, front with the setiger-
ous punctures over the eye extremely indistinct. Ej'es moderately prominent,
close to the mouth beneath. Labrum short transverse, feebly emarginate and
sexsetose in front. Mandibles moderately robust, arcuate, acute at tip. Maxillae
ciliate within, (the inner lobe not hooked in Basolia), the outer lobe slender,
biarticulate, the palpi rather stout, the last joint oval rather obtuse. Mentum
transverse, deeply emarginate and toothed, the lateral lobes obtuse, obliquely
truncate, ligula feebly prominent, tip free for a short distance and arcuate, bisetose,
paraglossiB semicorneous, not longer than the ligula (spinuluse at tip in Basolia),
and united to the ligula by a translucent membrane, palpi rather slender, the
last two joints equal in length the penultimate bisetose in front. Thorax more or
less quadrate, not narrowed at base, the setigerous punctures entirely obliterated.
Elytra not wider at base than the thorax, sides narrowly inflexed, margin entire,
apices truncate or rounded, surface striate, without scutellar stria, dorsal punc-
tures ?. Prosternum not prolonged. Mesosternal epimera narrow. Metasternal
epimera distinct, posterior coxae contiguous. Legs rather stout, the tibiae not
carinulate, the spurs rather small, the anterior tibiae dilated at tip, the outer angle
rounded, inner side deeply emarginate. Tarsi rather stout, claws simple.

The anterior tarsi of the males have four joints moderately dilated and biseri-
ately squamulose beneath.

I regret that I can only imperfectly formulate the characters of this
tribe. I know only one specimen of Basolia nitida Sol. It may be
almost unnecessary to state that the tribe is not the equivalent of
Lacordaire's Cratocerides which equals nearly the Dapti of the present
essay. Lacordaire was unfortunate in naming his tribe after a genus
entirely unknown to him and which by no means typified his idea
of the tribe.

To Baron Chaudoir we are indebted for a proper description of the
tribe and an association of genera which seem naturally to belong
together, (Ann. Belg. 1872). From my own study I would place these
insects not far from the Lebiide series, the ligula even being quite
suggestive of that idea. I do not perceive a close relationship with
the Morionini but rather with the Helluonini.

The three genera are Basolia (= Catapiesis), Cratocerus and Brach-
idius, the first two from , Brazil, the third from the Philippine Islands.
There is nothinu' allied to them in our fauna.

Tribe XXXIX.— Orthogonini.

Antennse of variable length, more or less compressed beyond the third joint,
three basal joints glabrous, inserted under a slight frontal ridge, the condyle
however visible. Eyes moderately prominent, close to the mouth beneath. Head
short, oval, not constricted, front with two supra-orbital setse, clypeus moder-
ately prolonged, its front margin subcoriaceous, a setigerous puncture each side.
Labrum quadrangular, moderately prominent, apical margin sexsetose. Mandibles
slightly prominent, arcuate, acute at tip. MaxilliB usually hooked at tip, (except
Anoncopeucus), ciliate within and sometimes at tip, the outer lobe slender, palpi
moderate in length, last joint subcylindrical or ovate, apex obtuse. Mentum
emarginate without tooth, the emargination nearly filled with the basal membrane
of ligula, the latter moderately prominent, corneous, 2 — 6 setose at tip, the para-
glossse large, auriculate, and longer than the ligula, the palpi moderate, the last
two joints equal, the penultimate bisetose in front. Thorax broader than long,
lateral margin acute, depressed and without setigerous punctures. Elytra oblong
usually depressed, base margined, sides narrowly inflexed, margin entire, apex
usually truncate sometimes almost rounded, surface striate and with three dorsal
punctures, the first on the second interval near the third stria, the posterior two
near the second stria. Prosternum not prolonged. Mesosternal epimera narrow.
Metasternal epimera distinct, the posterior coxae contiguous. Legs moderately
stout, the tibise on the outer edge sulcate and carinulate, the carinae crenulate and
finely spinulose; anterior tibi« moderately stout, the outer apical angle acute,
inner side emarginate, tibial spurs moderate in length. Tarsi moderate in length,
the fourth joint emarginate or bilobed, the claws slender, simple or pectinate.

The tarsi on all the feet are dilated in both sexes and are either densely pubes-
cent or densely papillose beneath.

The only species of this tribe that I have been able to procure for
dissection is Orthogonius acrogonus Wied., in which I find the ligula
distinctly free at tip, the paragloss^ large and auriculate extending
beyond the ligula and united hehind the ligula by a thin translucent
membrane (108).

It is interesting to find that in this tribe we have a genus with
the maxillae obtuse at tip, a character very irregularly diff'used in
the Carabida3.

As indicated above the elytra are variable at tip, being either entire
or feebly truncate. Exceptional cases of this kind must be expected in
so extensive a family.

In the present tribe the characters seem to indicate an aberrant
Truncatipenne with decided Harpalide affinities, Gh/ptus forming a link
in the line of affinity. As Zabrus seems to be the link between the
Fteroaticliini and Harpalini, so Orthogonius is between the Truncati-
penne complex and the Harpalini.

An interesting essay on this tribe by Baron Chaudoir will be found
in the Annales de la Soe. Ent. Belg. xiv, pp. 95 — 130, in which will be
found an expression of opinion very nearly the same as that above.

AMERICAN COLEOPTERA. 165

Harpalin^ UNISETOS^.

This section is not by any means as large as the preceding, the tribes
numbering only a third and the genera even less proportionately numerous.
The essential character of this section is the presence of but one supra-
orbital seta. This carries with it the tendency to a loss of the seta at
the hind angle of the thorax, in fact the existence of this seta either at
or near the hind angle is more of au exception here than its absence is
in the Harpalinse bisetosse.

The elytral plica exists in some of the tribes here and in about the
same proportion as in the preceding section, and it is by this means that
we can trace some affinity with Pterostichini on the one side or
L 6 b i i n i on the other.

The setigerous puncture on the outer side of the mandible is also
observed here in a relatively greater number of tribes but in far
fewer genera.

Of the eight tribes which follow six have representation in our fauna,
the Apotomini and P e 1 e c i i n i being absent, while Z a c o t i n i
is peculiar to it.

Mesosternal epimera usually wide, sometimes nearly as large as the episterna,
elytra truncate. Mandibles with setigerous puncture. Posterior coxse
often separated, the first ventral segment risible between them.

Tribe XL. Brachynini.
Mesosternal epimera very narrow and indistinct, elytra always entire.
Mandibles with setigerous puncture on the outer side. Abdomen peduncuhite.
Thorax not margined at the side, its sutures beneath obliterated. Middle,
and posterior tibice emarginate on outer edge at tip. Antennae with two
glabrous joints. Posterior coxse separated. Labial and maxilhuv palpi

elongate ; Tribe XLL Apotomini.

Thorax margined, sutures distinct. Middle and posterior tibiae not emarginate.
Palpi not long. Posterior coxse contiguous or but narrowly separated.

Tril)e XLII. Broscini.
Mandibles without setigerous puncture.
Posterior coxse distinctly separated.

Bod}'^ pedunculate. Elytra not margined at base Tribe XLIII. Zacotini.

Body not pedunculate. Elytra margined at base Tribe XLIV. Peleciini.

Posterior coxse contiguous.

Elytral margin more or less interrupted and witli an internal plica. Antennae
with three glabrous joints.
Anterior tarsi of male with three, rarely four, joints spongy pubescent

beneath. Elytral plica feeble Tribe XLV. Chlaeniini.

Anterior tarsi of male with thi-ee joints dilated and squamulose beneath.

Elytral plica strong Tribe XLVI. Zabrini.

Elytral margin not interrupted, no internal plica. Antennse with two, rarely
with three, glabrous joints. The male tarsi variable.

Tribe XLVIL Harpalini.

(a7)

166 GEO. H. HORN, M. D.

Tribe XL. — Brachynini.

Antennae slender, the condyle of the basal joint exposed, two basal and a portion
of the third joint glabrous. Head gradually narrowed behind the eyes forming
a neck, front with one supra-orbital seta, clypeus moderately prolonged. Labrum
broad, truncate. Eyes oval, oblique, narrowly separated from the buccal open-
ing. Mandibles stout, feebly arcuate and with a setigerous puncture externally.
Maxillse hooked at tip, ciliate within and at the tip, the outer lobe slender,
%vith equal joints, the palpi moderate, the last two joints more or less pubescent.
Mentum moderately broad, emarginate, toothed or not, the ligula in great jjart
membranous, the oval centre corneous and bisetose at tip, the paraglossse broad,
adherent and ciliate at tip, the palpi moderate in length, the second joint longer
than the last and plurisetose in front. Thorax with short marginal setse, no special
seta at the hind angle. Scutellum distinct. Elytra not margined at base, narrowly
inflexed, margin not interrupted, no internal plica, apex truncate and with a
membranous border, disc not striate and without dorsal punctures. Prosternura
not prolonged at tip. Mesosternal epimera broad. Metasternal epimera distinct,
the posterior cox£e either contiguous or separated. Middle and posterior tibiae
finely ciliate or spinulose externally, the anterior deeply emarginate within, the
inner spur at the summit of the emargination. Tarsi slender, the fourth joint
feebly emarginate, the anterior of the males with three joints feebly dilated and
squamulose beneath.

This is one of tlie tribes the composition of which seems at present
free from differences of opinion. Its position among the other tribes
seems, however, far from settled, and I would merely suggest that it be
placed after the Graphipterini for want of a better place although its
wide mesosternal epimera exclude it, not only from any intimate associa-
tion with these, but also any of the tribes of the present sub-family
excepting the Ozsenini and the two adjacent tribes. With the latter it
can hardly be said to have much affinity.

The only genus occurring in our fauna is Brachynus and to this it is
necessary to direct our attention. In the general diagnosis the posterior
coxae are said to be either contiguous or separated. It will be observed
in the larger species that many of the specimens have the coxae plainly
contiguous, the smaller species have the coxae separated and in the case
of carinulatus rather widely, so that in the present genus a character
shrinks into insignificance which ifi other parts of the series is of the
highest importance. This is one of the few instances known to me in
the entire Carabide series in which a really important character ceases to
have its full value.

On the other hand the apparent increase of the number of the
abdominal segments to seven or eight has been exaggerated in value
very far beyond its importance. If we examine the species of any of
the genera which emit from the anus a liquid whether explosive or not, it
will be seen that the structure in no way differs from that of Brach/nus
except that the latter has a broader sixth segment which, being truncate

AMERICAN COLEOPTERA. 167

or slightly emarginate, allows the genital armature to become more
plainly visible and we thus count more segments. Galerita and any
of the larger Dryptini will illustrate the above ideas.

The species of Brachynua are found under logs and stones usually
in damp situations and often in colonies. Those in our fauna have the
head, thorax and legs yellowish, the elytra blue. They have not yet
been separated in any satisfactory manner.

Tribe XLI. — Apotomini.
Antennse slender arising under a slight frontal ridge, two basal joints glabrous',
third very little longer than the fourth. Head broader behind the eyes, front
with one supra-orbital seta, elypeus moderately prolonged. Labruni short, trun-
cate. Eyes oval, not prominent, narrowly separated from the mouth beneath.
Mandibles arcuate, acute at tip and with a .setigerous puncture extei'nally. Maxillte
hooked at tip, ciliate within, the outer lobe rather slender, biarticulate, the palpi
very long and slender, the joints hairy, the last shorter than the preceding and
pubescent. Mentum broad, feebly emarginate without tooth, ligula moderately
prominent, rounded at tip and with four long setse, the paraglossse adherent,
a little longer than the ligula and obtuse at tip, the palpi slender, second joint
plurisetose in front, last joint a little shorter, slender, acute at tip and hairy.
Thorax globular, truncate in front, tubularly prolonged at base, sides not margined,
sutures entirely obliterated, sides with but one setigerous puncture at middle,
none at hind angle. Body subpedunculate, scutellum very small. Elytra oblong,
sides narrowly inflexed, obliquely sinuate near the tip which is somewhat pro-
longed, no internal plica and no marginal ocellate punctures and no dorsal punc-
tures. Presternum not prolonged at tip. Mesosternum nearly vertical in front,
the eoxse rather widely separated, the epimera narrow and indistinct. Metasternal
epimera distinct. Posterior coxae rather widely separated, the first ventral segment
distinctly visible between them. Femora stout, especially the anterior. Tibise not
ciliate or spinulose, the anterior deeply emarginate within, the inner spur superior,
middle and posterior tibiae obliquely grooved a)id emarginate at the outer apical
angle. Tarsi slender in both sexes, claws simple.

This ti-ibe contains only Apotomus which occurs in Europe, East
Indies and Australia. It has been placed near Bemhidhtm and Scarites
by Latreille. Dejean removed it to the Ditomides in which position
Lacordaire leaves it. Duval (Genera i. p. 43), recognizing its want of
affinity with these, forms of it a distinct tribe which he places between
the Clivinites and Ditomites, a line of affinities which seems as unnatural
as any that could have been chosen. It seems to me better placed near
the Broscini as one of the most sharply defined tribes of the sub-family.

Tribe XLIL— Broscini.

Anteuufe moderate in length with a variable number (three to five) of basal
joints glabrous. Head not constricted but usually gradually broader behind the
eyes, front not sulcate, one supra-orbital setigerous puncture and often with a post-
orbital cicatrix. Eyes oval, distant beneath from the mouth. Clypeus moderately
prolonged with lateral setse. Labrum moderately prominent, slightly emarginate.

1<)8 GEO. H. HORN, M. D.

Mandibles arcuate at tip with a setigerous puncture on the outer side. Maxillge
with the inner lobe hooked at tip, ciliate or spinulose within, outer lobe moderately
stout, biarticulate, the palpi rather stout, the last joint longer than the third,
elongate-oval or fusiform. Mentum broad, deeply emarginate, toothed or not. the
ligula moderately prominent, truncate and bisetose at tip, the paraglossse adherent,
sometimes free for a short distance and rarely longer than the ligula, the palpi
rather stout, the last joint a little longer than the second, more or less oval in
shape, (impressed beneath in Miscodera) , the second joint bisetose in front. Thorax
more or less ovoid, the sides narrowly margined and bisetose, the posterior seta in
front of the hind angles. Body pedunculate, scutellum in the peduncle. Elytra
not margined at b^se, sides narrowly inflexed, margin not interrupted posteriorly
but with a short internal plica, disc without dorsal punctures. Prosternum obtuse
at tip. Mesosternum rather wide, oblique, the epimera narrow. Metasternal
epimera distinct, posterior coxse contiguous or very narrowly separated. Legs
moderately stout, the tibise not spinulose externally, the anterior moderately
dilated at tip, deeply emarginate within, the inner spur at the upper angle of the
emargination. The tarsi filiform, fourth joint simple.

The anterior tarsi of the males may have four, three or two joints dilated, their
vestiture usually hairs, rarely squamules.

The creation of this tribe under the name of Cnemacanthides is due
to Lacordaire. Dioctea has been removed by Schaum (Ins. Deutschl. i,
p. 353), to the Ditomides, but Promecogvathus was added, the mistake,
however, having been corrected on a subsequent page, (p. 773).

The Broscini have a sUght sub-ocular ridge at the side of the head.
This ridge is well marked in the CicindeUdas but I have not observed it
elsewhere in Carabidae.

The latest revision of the tribe is by Putzeys, (Stett. Zeit. 1868,
p. 305 — 379), who recognizes seventeen genera and by the characters
given of the first six, some of them might with propriety be removed
to form a tribe between the present and the Harpalini.

In our fauna we have but one genus represented by two species.

MiscoDERA Esch. — In form the species resemble a large Di/schirius.
The two species are :

M. ARCTICA Payk. — Occurs in northern Europe and in Siberia where
it has received the name erythrojpus Mots., crossing to Alaska it becomes
americana Mann., and it finally reaches Newfoundland under the name
Hardi/i Chaud. It is all one species varying in size and brilliancy of
surface in the different localities.

M. INSIGNIS Mann., is altogether different. The anterior half of the
thorax is ovate, the basal half prolonged, somewhat like Promecognatlms.
It occurs in Alaska.

I have in the next tribe given my reasons for removing Zacotiis, and
in the same place and in Peleciini will be found remarks on the affinities
of these two tribes with the present.

Tribe XLIII.— Zacotini.
Antenna filiform arisine; under a slight frontal margin, first joint stouter,
cylindrical, third a little longer than the following, the first four joints glabrous.
Head subquadrangular, slightly constricted at a distance behind the eyes, a distinct
temporal cicatrix, front with one supra-orbital seta, clypeus slightly prolonged and
with the usual setigerous puncture each side. Eyes round, moderately prominent
and distant from the buccal fissure beneath. Labrum transverse feebly emargin-
ate, sexsetose in front. Mandibles not prominent, arcuate at tip only, acute and
without setigerous puncture externally. Maxillse eiliate within, hooked at tip,
the outer lobe rather stout, biarticulate ; palpi stout, the last joint shorter than the
preceding, oval and truncate at tip. Mentum transverse, emarginate and acutely
toothed, the epilobes acute and prominent; ligula moderately prominent, tip
arcuate and free with two setre, paraglossfe free for a short distance at tip which
is acute, shorter than the ligula; palpi moderate, third' joint elongate-triangular,
slightly arcuate, truncate at tip, the preceding joint shorter and bisetose in front.
Thorax ovate, slightly constricted behind, margin distinct, two lateral setse, one
near the middle, one' in front of base. Body pedunculate, scutellum not visible.
Elytra oblong-oval, humeri rounded, base not margined, sides narrowly inflexed,
margin entire not interrupted posteriorly without internal plica. Prosternum not
prolonged. Mesosternum obtuse in front, rather widely separating the coxae, the
epimera distinct, broader externally. Metasternum short, body apterous, epimera
distinct, posterior coxse slightly separated. Legs rather slender, middle tibise
slightly spin-ulose externally near the tip, anterior tibife moderately dilated,
emarginate internally, the inner spur at tlie upper angle of the notch. Tarsi
slender, the fourth joint simple.

The males have four joints of the anterior tarsi quadrangularly dilated, the first
three with squamiform papilla; beneath, the middle tarsi are not dilated but the
first two joints are squamulose beneath.

While I regret the muUiplication of tribes I aui unwilling to place
Zacotus either in the Broscini or Peleciini, and uiu8t therefore make it
the type of a separate tribe.

In size and general appearance (except the head) it resembles J'rome-
coderus concolor Germ. The head is subquadrangular, slightly pro-
longed behind the eyes and then constricted but to a less degree than in
Pelecium, the front has similar longitudinal depressions but less marked.
The body is pedunculate as in the Broscini but the palpi are more nearly
those of Felecium. The maxilkc are hooked at tip in Zacotus and the
Broscini, not hooked in Pelecium. The niandibles have no setigerous
puncture.

Zacotus seems therefore to form a tribe with nearly e(|ual relations
with the Broscini and Peleciini, and to indicate that these two tribes are
far more closely allied than any one has yet admitted.

But one species Z. Matthewsii Lee, occurs in Washington Territory
and Vancouver. I am informed by Mr. Morrison that it lives near
small streams in dense woods. It is piceous with bright :>3neous or
cupreous surface lustre.

Tribe XLIV.— Peleciini.
AntennsB moderately long, filiform, arising under a distinct frontal ridge, first
joint stout, a little longer than the others, 2—11 subequal, the first three joints
glabrous. - Head quadrangular, suddenly narrowed at a distance behind the eyes
to a neck which broadens in a semiglobular manner, front with one supra-orbital
seta and with a cicatrix behind the eye, clypeus moderately prolonged and without
lateral setigerous punctures. Eyes small, oval, and very distant from the buccal
opening. Labrum transverse, concave and emarginate, with six setse, the outer
one on each side vertical and longer, functionally replacing the clypeal seta.
Mandibles stout, prominent, decurved, arcuate, acute at tip, without external
setigei-ous puncture. Maxillae slender not hooked at tip, ciliate within, outer lobe
slender, biarticulate, the palpi stout, the outer joints setose, the terminal joint
securiform or oval-truncate. Mentum transverse, the lateral lobes obtuse at tip,
emarginate with an acute tooth as long as the lateral lobes. Ligula moderately
prominent, arcuate or truncate in front and bisetose, the paraglossse adherent at
the sides, free and slender at their tips and ciliate within, palpi stout, terminal
joint longer tlian the second, securiform or oval-truncate, second joint bisetose
in front. Thorax margined at the sides and with two setigerous punctures, the
posterior distant from the hind angles. Body not pedunculate, scutellum more
or less distinct. Elytra more or less distinctly margined at base, the humeri
prominent, fifth interval at base often subcarinate, sides narrowly inflexed, margin
slightly interrupted posteriorly but Avith a well marked internal carina, disc
without dorsal punctures. Presternum not prolonged at tip. Mesosternum obtuse
in front, the epimera very narrow. Metasterual epimera very indistinctly sepa-
rated, the posterior coxse separated rather widely, the first ventral segment visible
at middle. Legs moderately robust, the tibiae not ciliate or spinulose externally,
the anterior moderately wide, deeply emarginate internally, the inner spur remote
from apex but situated posteriorly. Tarsi not slender, the fourth emarginate
or bilobed.

The tarsi of the front and middle legs have four joints dilated and densely
pubescent beneath in ))oth sexes, tlie males have sometimes the middle tibiae
arcuate.

This tribe contains but one genus Pelecium Kby., (Eripus BcJ.,
Augasmosomus Chd.'), with the species extending froui Mexico to Brazil,
all of which are of moderate size, and some {ci/anipes Kby.), with the
elytra recalling the sculpture of our DJrs^lua Init more convex. No
member of this tribe has been found in our fauna.

Kirby placed the genus between Cj/chrus and Fandgseua and is fol-
lowed by others. Dejean while placing it among the Harpalini remarks
that it does not well fit there. Lacordaire following Chaudoir places
it in a group Stomides which Schauni justly says has no fundamental
character and which is in fact the most heterogeneous tribe in Lacordaire's
Carabidaj. Schaum, however, while indicating that it must form a sepa-
rate group, (Berl. Zeitsch. 1860, pp. 128 and l'J3), writes around the
subject leaving us as much in doubt as to its position as before.

I do not believe there can be much doubt of the relationship of the
Peleciini with the Broscini through Baripus and Zacofus.

AMERICAN COLEOPTERA. 171

It is a singular character that the set^e which are found in the vast
majority of Carabidae, arising either from the middle of the side of the
clypeus or from its anterior angle, should be here (I speak especially
of P. cyanipes Kby.), functionally replaced by the lateral setae of the
labrum, which, instead of being directed to the front in the usual
manner, arise vertically and are long. The rather wide separation of
the posterior coxas does not appear to have been noticed. The temporal
cicatrix to which Putzeys directs attention (Stett. Zeitsch. 1868, p. 306),
is observed in Felecium as well as in Broscini.

Tribe XLV. -Chlaeniini.

Anteniife slender, rarely slightly compressed {Evoknes^ arising under a slight
frontal ridge, the three basal joints glabrous. Head not narrowed behind the eyes
to a neck, one supra-orbital setigerous puncture. Clypeus more or less prolonged
between the mandibles, often without the lateral seta. Eyes oval, moderately
prominent, more truncate behind in the Oodes. Labrum transverse, truncate
or emarginate, with three, four or six setse in front. Mandibles feebly arcuate,
without setigerous puncture externally. Maxillre slender, hooked at tip, ciliate
or spinous within, the outer lobe usually slender, biarticulate (except Callistufi),
the palpi moderately long, the terminal joint variable in form. Mentum broad,
usually emarginate ai^d toothed, sometimes feebly bisinuate in front (Evoleyies)
or even almost truncate (Brachylobusi, the basal suture always distinct, ligula
moderately prominent, usually free at tip and bisetose, the paraglossse membranous
more or less free at tip, longer or not than the ligula, elongate and slender in
AnomoglosKus and ciliate within, palpi moderate in length, the terminal joint
variable, the penultimate bi- or plurisetose or even without setse. Thorax variable
in form, the setfe of the margin either slender or entirely wanting. Body not
pedunculate, scutelhim distinct. Elytra margined at base, sides narrowly intiexed,
margin interrupted posteriorly and with a distinct internal plica, surface striate,
without dorsal punctures. Prosteruum prominent at tip but not prolonged. Meso-
sternum rather widely separating the coxre, grooved in front, the epimera narrow.
Metasternal epimera distinct, posterior coxse contiguous. Legs moderate, middle
and posterior tibise finely spinulose externally, the anterior moderately broad,
a few stout spines at the outer apical angle,, within deeply emarginate the inner
spur at the angle of the emargination. Tarsi slender, claws simple.

The males have three or four joints of the anterior tarsi dilated and densely
spongy beneath.

After the very able papers by Baron Chaudoir on this tribe (Bull.
Mosc. 1856 and 1857 ; Ann. Mus. Civ. di Genova viii, 1876', it seems
entirely unnecessary to enter into any further discussion of the subject.
I can not realize the necessity for separating CaUistus as a distinct tribe
but his conclusion concerning Atranus seems to me just. CaUistus affords
one of the rare instances in Carabidae in which the outer maxillary lobe
is formed of one piece by the complete fusion of the two which usually
exist, without leaving any trace of suture as is the case in Ameriztis.
The mentum of BracJiylohus (117), is the most complete illustration of

172 GEO. H. HORN, M. D.

the obliteration of the usual emargination known to . me, although the
epilobal piece is very distinctly present.

The present tribe is divided into two groups :

Eighth stria of the elytra with its oeellate punctures distant from the margin,
the ninth stria very distinct. Eyes regular in outline not truncate behind.

Chl^nii.

Eighth stria very close to the margin, the ninth indistinct. Eyes truncate
behind Codes.

In the first group three genera occur in our fauna :

Mentuni witli distinct lateral lobes.

Toothed in tlie bottom of the emargination ChlseiiillS.

Not toothed AiioiiiogloMsus.

Mentum truncate in front ; Bracliylobus'.

In the second group the genera may still be the subject of discussion,
those represented in our fauna are recognized by the following characters ;

All the tarsi pubescent beneath.

Anterior tarsi % with four joints not widely dilated. Clypeus with a setigerous

puncture each side. Labrum 6-setose L<aclin<»crepis.

Posterior tarsi not pubescent beneath.

Anterior tarsi % with four joints dilated, the first three spongy beneath.
Clypeus without setigerous punctures. Labrum with six setse, the four

central small and close, the outer large and erect Anatrichis.

Anterior tarsi '^ with three joints dilated and spongy.

Second joint of labial palpi without setfe in front Oodes.

Second joint of labial palpi bisetose in front Evoleiies.

EvoLENES has the antennae somewhat flattened. The clypeus has
a large setigerous puncture each side and the labrum six. It is the
only genus in the group in which the second joint of the labial palpi
has the setae so universally observed in the Carabidae.

OoDES as above intended contains Oodes, Stenous and Crossocrepis
of Chaudoir. The latter is based on the supposed conformation of the
ligula which my own dissections prove not to exist. The other two
genera are separated by the mode of dilatation of the anterior tarsi.
In Oodes proper the clypeus has a setigerous puncture each side and
the labrum six in front, in the other two there are no clypeal punctures
and three only on the labrum.

The inconstancy of the setigerous punctures in the Oodes is re-
markable, the only one absolutely present in all is the one over the eye
The entire absence of these punctures from the side of the thorax
would be an excellent means of separating the Chlaenii and Oodes, were
it not that even in Chlfenius these punctures although constantly present
are often lost in the general punctuation and the seta is small and hair-
like and not very evident except in the glabrous species.

AMERICAN COLEOPTERA. 173

It may be observed in Chlaenius that those species in which the males
have not the pubescent space near the tip of the middle tibiae, that is,
those of my division A (Trans. Am. Ent. Soc. v, 1876, p. 257), are
without setae on the second joint of the labial palpi, while division B
(and Anomoglossus with its long second joint) is plurisetose.

Tribe XLVL— Zabrini.

AntennfB filiform, arising beneath a slight frontal ridge, the three basal joints
glabrous. Head short, without distinct neek, one supra-orbital puncture. Clypeus
very slightly prolonged, a puncture in each anterior angle. Eyes oval, relatively
small, not more convex than the sides of the head, distant beneath from the
mouth. Labrum feebly emarginate and plurisetose in front. Mandibles stout,
arcuate, more' or less obliquely furrowed above, without setigerous puncture
externally and feebly bidentate on inner margin. Maxillae strongly hooked at
tip with stiff" bristles within, outer lobe biarticulate, palpi stout, third joint longest,
fourth oval. Mentum broad deeply emarginate, variabh' toothed, the ligula
moderately prominent, apex free, truncate or bisinuate and bisetose, the para-
glossse obtuse and not longer than it, the palpi moderate, the second joint longer,
plurisetose in front, last joint somewhat oval, shorter than the preceding. Thorax
broad, as wide as the elytra, a setigerous puncture at the side but none at the
hind angle. Body not pedunculate, scutelluin distinc-t. Elytra narrowly inflexed
at the sides, the margin interrupted posteriorly and with a well marked internal
plica. Prosternum not prolonged. Mesosternum rather wide between the coxse
and broadly concave, the epimera narrow. Metasternal epimera distinct, posterior
coxae contiguous. Legs moderate, middle and posterior tibiae gradually broader to
tip, spinulo3e externally, the anterior of elongate-triangular form, spinulose at
outer api(!al angle, the inner side obliquely grooved, the inner sjjur not remote
from tip, the terminal spur short, broad, laminate at the sides and suddenly
narrower at tip. Tarsi filiform, fourtii joint simple.

The males have the first three joints of the anterior tarsi rather widely dilated
and biseriately squamulose beneath.

In some species the males have tlic apices of the middle and pos-
terior tibiae prolonged on the inner side in a dentiform process. By all
European authorities the anterior tibiae are said to have two spurs at
the apex and one above the emargination in the usual position. This
statement of the facts of the case seems to me a very loose expression.
All Carabidae have at the tips of the tibiae two spurs which are in all
cases articulated appendages of the tibiae. These in whatevei- language
used are called by the equivalent of our word "spur." That which
makes the so-called smaller terminal spur is merely a dentiform pro-
longation of the inner apical angle of the tibia which is in all respects
the homologue of the apical tooth of the middle and posterior tibia& of
certain males. I am not aware of any coleopterous insect having more
than two true tibial spurs and I therefore venture to object to any form
of exprcsNion conveying a fals3 idea.

It will also be observed that the anterior tibia; are far less emarginate

174 GEO. H. HORN, M. D.

than usual in the present series of Carabidse, and the structure of the
inner side may be compared rather to the deep oblique groove already
mentioned in some of the earlier tribes.

The ophiion expressed by Zimmerman that Zahrus should constitute
a special tribe seems to me far more nearly correct, than that expressed
by Lacordaire, Schaum and others in placing it in the Pterostichini.
It is however, as remarked by Bedel, an intermediate tribe between the
Pterostichini and Harpalini, with strongly marked characters of each
tribe equally present and yet abundantly distinct from either by the
structure of the anterior tibiae. The head and thorax are decidedly
Harpalide in structure while the elytra and anterior tarsi are Pterosti-
chide. The mouth parts do not exhibit any more decided relation with
the one tribe than the other.

Zahrus belongs to the Circum-iNIediterranean fauna extending to the
Caspian Sea.

Tribe XLVII. -Harpalini.

Antennre usiuilly slender arising under a slight frontal ridge, the two basal
joints glabrous, sometimes also the greater part of the third. Head often large,
usually moderate, not narrowed to a neck, with one supra-orbital seta. Eyes
usually moderate in size, never very convex, not distant beneath from the mouth,
sometimes however small and distant. Clypeus slightly prolonged between the
mandibles, with one or two setigerous punctures near the apical margin. Labrum
moderately prominent, truncate or emarginate, plurisetose in front. Mandibles
stout, rarely ( Glyptus) prominent, acute at tip and without setigerous puncture
externally. Maxillae hooked at tip ^except in Gli/ptus), although rather feebly in
some genera (ArLiitus), the inner margin ciliate, the outer lobe usually slender,
as long as the inner lobe but shorter in Glyptus. biarticulate, the terminal joint
often longer than the first, the palpi moderate, the terminal joint slightly oval or
subcylindrieal, sometimes slightly pilose. Mentum broad, emarginate, with or
without a median tooth which is sometimes as long as the lobes [Arifstvts) ; ligula
prominent, variable in form, the tip free (usually bisetose) and in most cases
dilated, the paraglossse variable in form always as long as, frequently longer than
the ligula and very often ciliate at tip, the palpi moderate in length, the terminal
joint never longer and very rarely equal to the preceding which is plurisetose
except in Glyptus where there are no setse. Thorax variable in form, with a
lateral seta, but none in the hind angles. Body sometimes subpedunculate,
scutellum distinct. Elytra usually margined at base, sides narrowly inflexed,
the margin variable but never with an internal plica, surface striate, often densely
punctured, either pubescent or glabrous, with or without dorsal punctures. Pro-

row. Metasternal epimera distinct, the posterior coxse contiguous. Legs variable,
often stout and fossorial. The middle and posterior tibiaj otten spinulose or even
serrulate externally, the anterior with the outer apical angle spinous or prolonged
obtusely. The tarsi variable in structure.

Sexual characters variable.

trivial characters, this tribe has become the most difficuh to study of
any in the Carabidse excepting possibly the Lebiini. Characters drawn
from the ligula and paraglossae have here as in the Lebiini been pushed
to an extreme, and a study of them from my own dissections proves
that in both tribes they have not the great value which has been assigned
to them. It seems to me better to reject them almost entirely, certainly
as a means of separating tribes or groups and possibly even genera.

The tribe Harpalini as here intended contains the Ditomides of
Lacordaire, (G-enera i, p. 165), the Cratocerides, Anisodactylides and
Harpalides of the same author, and I add also Glt/ptus.

From the Ditomides all authors who have studied it agree that
Apntomui^ should be removed. From the Cratocerides Cydosonms
should be removed as suggested by Schaum and Chaudoir and placed,
as indicated by the latter in the Lebiini, ^Bull. Mosc. 1872*. ISomo-
platus and Macracnnthus are allied to Masoreus, (Schaum, Berl. Zeits.
1800, p. 178; Chaudoir, Bull. Mosc. 1870, Monog. des Masoreides\
After all this dismemberment Chaudoir forms of Crafocerus, Bruchidio
and Basolia a special group, " plus ou moihs voisin des Drimosfoma:'
Among the Anisodactylides Orthogonius and Mlgodops should be re-
moved, the former constituting a distinct tribe near the Lebiini, the
latter being a member of the first sub-family. The Harpalides does not
appear to contain any offending material.

To the tribe must hi added Fo/pochi/u (for wliicii however, Lacor-
daire uses a synonym Melunotna Dej. , and Stenomorphus, the affinities
of the latter having been properly recognized by Schaum.

From my own study I am convinced that Gtyptus can find no better
place than as a group in the present tribe. The genus was described
by Brulle who placed it in the Ditomides, a position which does not to
me seem so erroneous as Lacordaire intimates. The latter author places
it in the most heterogeneous of his tribes (^Stomides) near Idiomorplius
to which it seems not to be greatly allied, although Schaum (Berl. Zeits.
1800, p. 178), says that these two genera are Orthogoniens, while Chau-
doir properly omits them from his monograph of that group, (Annales
Belg. xiv, 1872). Idiomorphus is known to me by the figure which
Lacordaire gives and I can therefore express no opinion.

The characters of Glyptus are decidedly those oi' a Har[)alide and
I think it can very properly be compared with our own Geopinua.
In both genera it will be observed that the antenmii are rather short
and quite distinctly geniculate, the third joint feebly pubescent at tip
in Geopinus and almost entirely glabrous in Glypfus. In both genera

17() GEO. H. HORN, M. D.

the following joints are pubescent at the edges only the middle being
glabrous. The legs are similar, the anterior tibiae especially, so. The
mouth parts are also of the same general type observed throughout
the Harpalini, especially Nothopus and Piosomu. It will be observed
however that the maxillae are not hooked at tip although acute, and the
outer lobe considerably shorter than the inner, a character which I have
not elsewhere found in the Carabidc«. The tarsi are also truly Harpalide,
the male having four joints of the anterior and middle pairs dilated and
biseriately squamulose. Finally, the position of the tactile setas of the
head and thorax show that Glyptus must be placed in the present series.
The tribe Harpalini may be divided primarily by the tarsal vestiture
of the male into three series one of which may be again divided, the
four groups thus formed may be characterized in the following manner :

Anterior tarsi of male pilose or spinous beneath, usually feebly sometimes not at

all dilated Dapti.

Anterior tarsi of male dilated and biseriately squamulose.

MaxillfB not hooked at tip, the outer lobe much shorter than the inner, penulti-
mate joint of labial palpi not setose, labrum very short Glvpti.

Maxillae hooked at tip, the outer lobe equal to or longer than the inner, the

penultimate joint of labial palpi plurisetose, labrum normal Habpali.

Anterior tarsi of male densely spongy pubescent beneath Anisgdactyli.

The tarsal vestiture above outlined appears to be the only means yet
devised for the division of the tribe. It is not however without ex-
ceptions as certain Dapti, Geopinus for example have a few squamules
on the under side of the anterior tarsi, and certain Acinopus have the
anterior tarsi feebly dilated and the squamules rudimentar3^

Group Dapti.

The genera of this group present certain special characters which
require passing mention. In the majority of the genera the eyes are
small and beneath widely separated from the buccal fissure. In Daptus,
Polpochila, Acjonoderus and Pugonodaptvs the eyes are normal in form
and close to the mouth beneath. The mandibles of Geopinus, Daptus
and Pogonodaptns are normally decussating, the left overlapping the
right with its tip somewhat chisel-shaped and deeply strigose in the
first two genera, acute and not strigose in the third. In all the other
genera mentioned below the light mandible appears to be shorter than
the left and is capable of being drawn more within the mouth, its
chisel-shaped tip passing along the obtuse inner edge of the left re-
minding me of the manner of the articulation of the lower mandible of
the Parrot on the upper or like the incisor teeth of a Kodent.

Daptus has also a small triangular plate over the insertion of the
antennjxi as observed in Ditomus.

AMERICAN COLEOPTERA. I"*"?

On examiniug the under side of the head the usual setaB may be seen
at the middle of the mentum, one on each side and behind the base of
the mentum tooth and which may for convenience be called post-dental
set?e. In all the genera with one exception there will also be seen two
setigerous punctures at the side of the submentum immediately behind
the°angle of the mentum. In Polpochila and Agonoderm the two setae
are quke conspicuous, the inner one of each pair, however, larger than
the outer, but in the other genera the outer seta gradually becomes
more and more feeble so that it finally disappears or can only with great
difficulty be found. In Geopinus however there is but one seta on each
side and this is situated in the posterior angle of the mentum itself.

The anterior tibiae are usually gradually dilated to apex and spinous
at tip externally, but in Geopinus the outer angle is expanded in a plate,
spinulose on its edge resembling in general form that of Glyptus. In
Nothopus the outer angle is more narrowly prolonged and rather deeply
sinuate above the tooth. Daptus has a thicker anterior tibia the outer
angle rounded, the posterior face rather closely beset with spinules as
in Phaleria, the fossorial habits of which it imitates.

The following table will enable our genera to be recognized :

Mandibles prominent, decussating. Body subpedunculate.

Mandibles deeply stri.i;ose at tip. Anterior tibife decidedly fossorial.

Eyes small. Mentum with a seta at hind angles CJeO|Uiius.

Eyes large. Setse at sides of submentum Daptus.

Mandibles acute at tip not strigose. Anterior tibia not foss.-rial. No seutellar stna.

Head with deep arcuate impression each side Pogouotlaptus.

Mandibles not prominent, at most feebly decussating. Body not peduncvilate.

Outer apical angle of anterior tibite prolonged Motliopus.

Outer apical angle of tibise not prolonged.
Mentum toothed.
Apical angles of joints 1—?. of anterior tarsi prolonged in spines. Eyes

large. Hind angles of thorax obtuse or rounded Polpochila.

Apical angles of joints of anterior tarsi not prolonged. Eyes small. Hmd

angles of thorax sharply rectangular fralacaiiUlUS.

Mentum not toothed.

Posterior tarsi with the first joint a little longer than the second, outer
edge of middle tibire rather flat and with a double row of spinules
closely placed.
Eyes relatively small, distant beneath from the mouth ; elytra with

numerous dorsal punctures Fiosoma.

Eyes relatively large, very narrowly separated from the mouth ; elytra

'with one dorsal puncture Agoiioderus.

Posterior tarsi with the first joint nearly as long as the next three.
Middle tibiae with the spinules sparsely placed, in the male arcuate
and serrate on the inner side.
Eyes rather small; three series of elytral punctures.... Discoderus.

' TKANS. AM. EXT. see. IX. '40) OCI OCKK, 1 SSI .

178 GEO. H. HORN, M. D.

The sexual characters are not very well marked. The males have four
joints of the anterior tarsi feebly dilated (two in Folpochild) and rarely
{Discoderus) with a few squamules beneath. The latter genus has the
middle tibiae distinctly arcuate and serrate within. In Cratacnnthus the
right mandible of the male has the basal portion which borders the
clypeus more elevated, while the upper edge in front of this is much
depressed, a similar structure is observed in Aciaopus.

The Ditomides of Lacordaire should not in my opinion be widely
separated from the present group. The only character in which they
differ is in the apex of the ligula being plurisetose. Their punctured
surface gives them a somewhat different aspect but this has a parallel in
Dichirus in the Anisodactyli and Ophonus in Harpali.

To this group belong also Cratognathus placed by Lacordaire in the
Anisodactyli and Puramecus of his Harpali.

I have introduced Daptus in the above table for convenience of
comparison, it does not occur in our fauna. The genera above men-
tioned differ to a greater or less extent in the form of the ligula and
paragiossae as well as in the extent of pilosity of the tei'minal joint of
the palpi. Agoiwderun and Pogonodaptua are the only genera in which
I have observed the penultimate joint of the labial palpi to be bisetose.
Nothopun and Piosoma have the ligula quadrisetose . and the paraglossfe
ciliate externally at tip, the upper surface is also sparsely setose in these
genera. In Oratacanthus the paraglossas are very broad and lie behind
the ligula, so that when viewed from the front the entire ligula has very
much the appearance of that of a Lebiide.

The name Pogonodaptus is proposed for a small species resembling
Daptus arid somewhat also Pogonus (Pogonistes), which has the fol-
lowing characters.

POGONODAPTUS n. g.

Head moderately large, horizoutal, not narrowed behind the eyes to a neck.
Eyes moderately large and prominent, narrowly separated from the mouth.
AntennsB arising under a slight frontal ridge, the second joint a little shorter
than the third. Clypeus slightly prolonged between the mandibles, narrow,
emarginate in front, a seta in each angle. Labrum broadly emarginate, sexsetose.
Mandibles prominent, decussating, feebly arcuate, tips acute, a slight tooth at the
middle of the right. Mentum broad, feebly emarginate, a short broad tooth at
middle. Ligula small, free and bisetose Mt tip and narrowed, the paraglossse
falciform a little longer than it, the palpi slender, penultimate joint a little longer
than the last and bisetose. Maxillary palpi moderate in length, the terminal joint
slender, slightly fusiform, a little longer than the preceding. Thorax transverse,
narrowed behind, posterior angles distinct. Body pedunculate. Elytra oblong,
parallel, very slightly sinuate near the tip, surface striate, without scutellar stria,
a dorsal puncture on the third interval near the second stria. Anterior tibire

AMERICAN COLEOPTERA. 179

not fossorial, the outer edge spinous, middle tibise on the outer edge biseriately
spinulose, the posterior more finely so. Posterior tarsi slender with joints 1 — 4
gradually decreasing in length.

This genus is known from any in the tribe by its prominent
and smooth mandibles, the non-fossorial tibiae, the absence of scutel-
lar stria, while the form of the ligula and paraglossse distinguishes
it from Daptus.

P. piceus n. sp. — Moderately elongate, parallel, piceous, shining, legs pale
testaceous. Head smooth, a moderately deep arcuate impression each side. An-
tennfe piceous, two basal joints pale. Tliorax transversely cordate, sides arcuate
and narrowing posteriorly, hind angles small moderately prominent, base arcuate,
^pex very feebly emarginate, disc moderately convex, median line finely impressed,
a short intra-angular basal impression, surface jmooth, shining. Elytra oblong,
parallel, humeri obtuse, surface striate, the striae, entire and not punctate, no
scutellar stria, intervals flat, smooth. Body beneath piceous, shining, tip of
abdomen paler, surface smooth, impunctate. Length .24 inch ; 6 mm.

I have but one specimen, a female, from Texas, given me by Mr. A.
S. Fuller.

Group Glypti.

I have already given the reasons not only for placing Glyptus in
the present tribe but also for considering it a group apart. With the
exception of the characters which mark it as a special type in the tribe
it seems to bear the same relation to the Harpali which follow, that
Geopinus does to other Dapti. G. scu/pfi/is Br., is figured by Lacor-
daire (Genera, Atlas, pi. 10, fig. 3), in such a position on the plate as
to make its comparison with the better figure of Geopinus quite easy.
The species above cited occurs in western part of Africa and lives
in the nests of White x\nts. A second species has been described by
Chaudoir from Egyj)t.

Group Harpali.

It is extremely difficult to draw the line with accuracy between this
group and the Dapti, and I am convinced that other characters will be
found which will separate the genera but which will not allow the groups
to remain as at present con.stituted.

Not having access to as much exotic material as I desire I cannot
venture on a discussion of the genera which should be here included,
and will confine my remarks to those of our own fauna.

At the time of the publication of the " Classification of the Coleoptera
of North America," by Dr. LeConte, six genera were placed in the
Harpali. Since then two have been suppressed Philodes (= Stenolophus)
and Gynandrotarsus (r= Anl&odactyhis). It is however necessary to
add Stenomorphus, and Selenopliorua should be rehabilitated as sug-
-:>s^-d1.v Dr. L:CaKj.

180 GEO. H. HORN, M. D.

I have already referred to the fact that in by far the larger number
of genera of Harpalini the labial palpi have the last joint shorter than
the preceding, while the latter is then more than bi-setose except in
Glyptus which seems to have lost the setse entirely. In the Dapti
Agonoderus has been referred to as one of the rare exceptions to the
rule and the terminal joint is as long or longer than the preceding and
the latter simply bisetose in front. The presence of a few hairs more
or less may seem a very trivial character, but when this is always
associated with another important structural character and is moreover
absolutely constant, it assumes an importance far greater than the slight
ligular differences which are apt to be described and even figured differ-*
ently by two equally competent students.

In order that the argument may be followed more easily it will be
better to discuss the genera separately, and will call the labial palpi
normal when the last joint is short and the preceding plurisetose.

Stenomorphus. — Labial palpi normal. Anterior tarsi of male moder-
ately dilated, the first joint nearly equal to the three following and not
squamulose beneath, the next three biseriately squamulose, the fourth
transverse feebly emarginate. Anterior tibiae ciliate within. Middle
femur with a triaugular dilatation of the anterior condyle at the knee,
the middle tibia slightly arcuate, middle tarsus not dilated. Mandibles
chisel-shaped at tip.

The female has the first joint of the anterior tarsi rather broadly
dilated and not spongy nor papillose, the tibia is not ciliate within. The
middle femur is not toothed at apex, the tibiaj slightly curved.

It will be seen by the above characters that the genus should not be
placed with Anisodactylus as stated by Schaum, much less with the
Pogonini as Lacordaire has done.

GrYNANDROPUS. — The labial palpi are normal. The anterior tarsi
are moderately dilated in the male, the first four joints biseriately
scjuamulose, the first about as long as the next two. The female is
as in Stenomorphus.

This genus makes a nearer approach to the true Harpali than the
]»recediiig.

TRioiiopsELAPHrs. — Palpi unknown, probably normal. The anterior
tarsi of male with four joints dilated and squanudose beneath, joints 1 — 4
decreasing gradually in length, the fourth emarginate. Posterior tibife
arcuate, inner edge crenulate and ciliate. In the female the first four
joints are dilated, the first strongly, much longer than any of the fol-
lowing joints, not squamulose or spongy beneath.

AMERICAN COLEOPTERA. 181

This genus occurs in Brazil and is introduced here as it shows some
relation with Discoderus of the preceding group while plainly a member
of the present.

AciNOPUS. — Palpi normal. In both sexes the anterior and middle
tarsi are dilated, and in the males biseriately squamulose beneath.

In this genus was first observed the difference between the right
and left mandible of the male to which I have called attention in
Cratacanthus. It occurs in Europe and is mentioned as one of the
links between the present group and the Dapti.

Harpalus. — Palpi normal. In the male the anterior and middle
tarsi are dilated and biseriately squamulose beneath, the fourth joint
emargiuate or subbilobed. In the female the tarsi are slender. The
posterior tarsi have the first joint never longer than the next two. The
elytra have one dorsal puncture or none. Paraglossae ciliate at tip.

Selexophorus. — Palpi normal. Sexual characters of //^»r/;^</i<.s. First
joint of hind tarsus e(puil to the next three. Elytra with three rows of
dorsal punctures. Paraglossae with at most one cilia at the sides.

A review of the species of our fauna will be found in Proc. Amer.
Philos. 8oc. 1880, p. 178.

Stenolophus. — Palpi abnormal, the last joint of the labial oval,
acuminate, the penultimate bisetpse in front. Anterior tarsi of male
with four joints dilated and biseriately S(juamulose beneath, the ftmrth
joint deeply bilobed, middle tarsi moderately dilated and squamulose.
First joint of hind tarsi about as long as the two following together.
The females have the tarsi slender, the fourth joint of the anterior
pair emargiuate.

In the above genus will be contained those species in our fauna
included by Dr. LeConte in his divisions A, B, D, (Proc. Acad. 1868,
p. ?)~(i). It will be observed that the last joint of the labial palpi is
more slender and less oval than in the species of his group C. I have
also observed that in some species this same joint is impressed or concave
beneath in the male, (/imbttlis,f(tli(jinosus, conjunctus, anceps, cincticolh's,
Jiavlpea and ochropezus), in others it is entirely simple, {ccnbonarhts,
plebejus and tfissimi/is). Several have not been examined as males are
not at hand. In souie species also the hind tarsi have a tine carina on
the outer side of the first three joints. The middle tarsi are sometimes
sulcate as in P/afi/mis. I mention these observations that they may be
made use of by future students of the genus.

AcuPALPUS. — Palpi abnormal, the terminal joint of the labial rather
stoutly oval but slender at tip. the penultimate bisetose in front. Ante-

(41)

182 GEO. H. HORN, M. D.

rior tarsi of male moderately dilated, biseriately squamulose beneath, the
fourth joint feebly emarginate. Middle tarsi feebly dilated but distinctly
squamulose. The first joint of posterior tarsi is distinctly shorter than
the next two' together. The females have slender tarsi.

Here also may be observed the depression in the last joint of the
labial palpi of the male. I was at first inclined to believe that this
might be a post-mortem character the result of contraction, but its
occurrence in males only seems to indicate that it is probably a character
found also in life, of a sexual import.

In this genus are contained those species in section C, (loc. cit. p. 377),
hydropicus, carus, lonfjulus, JiitvUimhus and rectangulus. Acupalpus
seems fully as worthy of being maintained as many of the genera of the
present tribe, if we reject its characters as invalid for generic separation
it will be almost impossible to separate genera in the group Harpali.

Bradycellus. — 'As far as the species in our fauna are concerned this
genus is a composite and contains three distinct forms.

First. — Labial palpi normal, the second joint longer than the terminal
and plurisetose in front. The anterior and middle tarsi are dilated nearly
equally and biseriately squamulose beneath, the fourth joint emarginate.
The antennae have the two basal joints glabrous and also a small portion
of the base of the third.

I believe the species so constituted should be placed in Hurpalus,
(Lee. Proc. Acad. 18G1, p. 374). They are dichrous, vulpecnlus and
autumnalis.

Second. — Labial palpi abnormal, the second joint bisetose in front not
longer than the last. Anterior tarsi of male normally dilated and
squamulose beneath, the fourth joint emarginate. Middle tarsi narrowly
dilated but distinctly squamulose. The antennae have three basal joints
entirely glabrous.

Here belong hadlipennls^ atrim,edrus, nigrinus, and one new species
all of which should be referred to the genus Tachycelli:s Morav.

Baron Chaudoir (Rev. Mag. Zool. 18(j8), first suggested the placing
of these species in Tuchycellns but the characters made use of were
of such a trivial nature that Dr. LeConte did not deem it advisable
to follow him. I can not myself agree with Chaudoir in adding also
vulpecidus, dichrons and autummilis.

In the same paper Chaudoir makes the first step toward the re-
establishment of Acupalpus in our fauna by the description of a new
species {re.ctangidus), included in the list above given.

Third. — The remaining species belong to Bradt/ccUas proper. The

labial palpi are as in Tachycellus. The anterior tarsi above dilated.
The middle tarsi about as slender as in the female. The antennae have
at most two basal joints glabrous and the second and often the first
are hairy.

From the above notes it will be evident that the genera are not easily
separable except both sexes are at hand. The iullowing table will assist
the student of our fauna.

most one dorsal puncture Harpaliis.

The last two genera do not occur in our fauna and are introduced in
the t;il)le for convenience of comparison. I observe that the three basal
joints are glabrous, that is, the third joint is not punctured and pubescent
in the manner of the following joints. It has it is true a few hairs but
the surface is like the second and not the fourth. In these genera the
hind angle of the thorax bears a long erect seta, presenting the only
instance in wliich this is the ca.se in genera with one supra-orbital seta.
Duval refers these genera to the Anisodactyli, but from the tarsal vesti-
ture they seem more properly to belong here.

As already remarked three species formerly placed in Bradycelhis

The essential character of this group is that the dilated tarsal joints
of the male are spongy pubescent beneath.

As constituted by Lacordaire it contains very diverse forms — Ortlio-
gonius is a distinct tribe, Oratognathus and Flowma are Dapti, Geo-
hsenus allied to Platt/nua ; Migadops, Loxomerus and Brachycoelus are
Carabinae, GynandropiiDi and Diavhromus go to the Harpali ; Gynandro-
tarsus has already been suppressed in Anisodacty/us, and I hope to
show good reasons for doing the same with Gynandromorphus.

The genus Anisodactylus not only gives its name to the group but is
also its central idea. From this as a starting point the relative values of
the genera may be discussed, as a convenient point of comparison.

In a ri!view of our species of the genus published by me, (Proc. Am.
Philos. Soc. 1880, p. 1(J2, etc.), will be found a full discussion of the
characters which serve to divide the species in subgenera and lower
groups — the trifid anterior tibial spur, the spur broader at middle and
the slender spur. In two species harpaloides and vpacidus, the first
joint t)f the anterior tarsus of the female is dilated and in the former
that joint is somewhat prolonged under the second.

Gynamh'nmorphua has the trifid anterior tibial spur in both sexes,
the first joint of the anterior tarsi dilated in the female while the
posterior tarsi are somewhat flattened and pilose above. In the first
character it is ecjually related to the Dichirus and Triplectrus groups of
Anisodactylus, by the second to the latter more especially and by the
third character to the former more especially. The upper surface is
densely and rather coarsely punctured and finely pubescent. I have
therefore no hesitation in placing Gynundromorphus as a division of
Anisodavtylus intermediate between the groups Dichirus and Triplectrus.

Xestonotus. — Anterior tarsi broadly dilated in the male, the first
four joints densely spongy pubescent beneath, middle tarsi' with four
joints less widely dilated and spongy pubescent beneath, the first entirely
glabrous, posterior tarsi slender and long. Elytra with one dorsal punc-
ture. The ligula is rather narrow and parallel, the paragloss«3 broad
and a little longer than it.

Comparing the diiferences between the ligula and paraglossse with
those observed in Ha r palm there does not seem any valid reason for

retaining tlie genus apart from Anisodactylus, and the species will
find a suitable position between the amaroidex and serkexis groups
of that genus.

Amphasia. — Here the characters are essentially those of Aniso-
dacti/Ins serlceus. The paraglossse are similar in form to Anisodactylus
and merely a little longer.

Anisotarsus.— The sexual characters and those derived from the
posterior tarsi are precisely those of Am'sodacfi/his coenus and Isetus.
The paraglossse are a little broader than in typical Anisodncfi/li.

Spon(Sopus.— The ligula and paraglosste are intermediate in structure
between the typical Anisodactt/lus and Xeslu7iofus, and the ligula is free
for a greater distance at tip. The sexual characters are those of the
amaroides group. The posterior tarsi are however slender. The elytra
being punctulate and with a single dorsal puncture this species forms an
intermediate between the discoideus group and serlceus.

From the above remarks it must be evident that my opinion is that
the above genera are inseparable from Anisodncti/lus. I have examined
the species from every possible standpoint and 4can find no reason either
from my own studies or the remarks of others to do otherwise than
su"":ested above.

While I have given these genera all the study possible with me
at present, I consider the question of the total suppression of Aniao-
ttirsus and Spoiujopns still open for further discussion, there is no
doubt in my mind, however, regarding Gi/niindrumorphus, Xestonotnn
and Amphasia.

It is worthy of note in Anisi.dartijlus that we may have more than
one setigerous puncture at each angle of the clypeus while in most
Carabidoe there is but one and even this may be lost.

Sub-Family FSE ID OM ORFHINjE.

>liddle coxal cavities enclosed by the central pieces of the mi^so-
aiid metasternum. Head without supra-orbital setfe and with grooves
beneath of variable extent for the reception of the antenna. Eyes in
great part superior, very widely separated beneath from the mouth.
Legs short, contractile, tarsi slender, rigid.

The genera which compose the present division are the most abnormal
of all Carabidce. That they belong to the family and should not be
separated is I believe now generally admitted, the only difficulty being
their proper position in the series, and from my own study they do
not seem to be well placed anywhere and are equally aberrant in any

position. The affinity so often mentioned in the direction of the Gyrinidae
seems rather feeble, and is expressed rather in an outward resemblance
of form than in the more important anatomical details. -

There seems to be an undiscovered form or possibly a lost type
to which certain tribes of the Carabinae and Harpaliuae as well as
Amphizoidae appear to point, and it is with this hypothetical centre
that the Pseudomorphinae seem to be allied. The tribes referred to
are Enceladini, Siagonini and Ozaenini. In the discussion
of the Gyrinidae there will be found important reasons why we cannot
suspect any relation between it and the presant sub-family.

One tribe alone forms the sub-family.

Tribe XLVIII. Pseudomorphini.
AuteniiPe usually slender, filiform, ooinpressed and subserrate in Ade/otopu.i
arising under a moderately dilated frontal plate, the three basal joints glabrous,
received in repose in grooves of greater or less length, within the eyes beneath
the head. Head short, obtuse, deeply inserted in the thorax, sides of front more
or less dilated and infringing on the eyes in front, clypeal suture rarely visible,
front without supra-orbital setse. Eyes oval, not prominent, usually confined
almost entirely to the upper side of head and widely distant from the buccal
fissure beneath. Labrum sRort, transverse, rounded in front and feebly sexsetose.
Mandibles short, broad, arcuate externally, sometimes slightly toothed within.
Maxillae slender, ciliate and spinous within, not strongly hooked at tip, the outer
lobe slender, biarticulate with the terminal joint longer, the palpi short and thick,
the terminal joint cylindrical, compressed, obliquely truncate at tip. Mentum
large without basal suture, deeply emarginate toothed or not, the epilobes narrow,
ligula and paraglossse variable in form, the palpi longer than the maxillary, the
terminal joint cylindrical and obliquely truncate or securiform. Thorax as broad
at base as the elytra and overlapping them, the lateral margin more or less ex-
planate and often fimbriate but without the usual setue. Elytra oblong, truncate
at tip, not margined at base, lateral margin acute, sides narrowly inflexed but
more widely near the base, the epipleurfe proj)er very narrow, no internal plica,
surface at most obsoletely striate without dorsal punctures. Scutellum distinct.
Prosternum narrow usually somewhat prolonged behind the coxae, the coxal
cavities very narrowly closed behind. Mesosternum very narrow between the
coxse. the epimera distinct, not reaching the cijxal cavity. Metasternal epimera
distinct, posterior coxse contiguous. Legs short not visible beyond the elytra, the
femora stout, rather deeply channeled beneath and receiving the tibiai, the latter
slender and with moderate terminal spurs, the anterior tibiae emarginate within,
the inner spur remote from the apex. Tarsi slender very feel)ly fiexile, the (daws
slender, feebly arcuate and simple.

This tribe is represented in -our fauna bv the j^rnus Haeudoviorplta
with three species.

In the two specimens of F. Cronkhitei before me the fourth and fifth
ventral seoments have at middle a short, transverse, pilose band, while
P. Behrensii my unique presents no such character. This may be
sexual. I have observed no other sexual diflPerences.

AMERICAN COLEOPTERA.

181

Our species are so rare that it was impossible to procure one for
dissection, and I have substituted Sphallomorpha quadrisignata Cast.,
from AustraUa, (see PI. Ill, fig. 4, also dissection 147).

Additional Notes.
On p. ya I have made xise of the expression that '-the (posterior)
coxae reach the side margin of the body, separating the metasternal
side pieces from the first ventral segment." By this I mean to be
understood, the side margin as it appears from the examination t)f an
entire specimen, the limit of the body being the margin of the elytra.
The extent of the coxse outwardly is such that the wide pieces become
more dorsal, they are never cut off from articulation with the abdomen
but merely hidden. It is not a question of greater or less inflexion
of the elytral margin, lus it will be observed in tho.se genera with most
widely inflexed elytra {C^chrus et al.), that the coxae do not attain the
side margin of the body.

-o-

From the families of Adephaga given on p. 94 there appears to
be a tendency on the part of some able entomologists to exclude the
G-YRINID.'F. I biilieve I have studied this type with some care and the
structure of the external skeleton as well as the mouth parts seem to me
so plainly Adephagous as to leave no room for douljt. It is true the
antennae are irregular in their form, the eyes are so broadly divided as
to make a superior and inferior i)air on each side, and in Dineutua X\w
outer or palpar lobe of the maxilla is lost. , These are certainly import-
ant characters but must not be allowed to outweigh all the rest of the
organizaticm. The Adephaga do not present an unbroken chain and in
its fragmentary condition some aberration must be expected.

After entering on the description of the various tribes recognized in
the preceding pages, I have used Lacordaire's first volume of the Genera
as a convenient means of comparison. It is well known that this volume
although not old in years is somewhat antiquated through the researches
of Schaum, Chaudoir and LeConte, but with all its defects it is the only
general system of Carabidae extant. Several authors have started in an
attempt to revise the system but beyond the arrangement of the genera
of local faunte nothing has been done. It has been easy enough as far
as the tribes of the Carabin^e extend, beyond this all is in confusion.
The present essay aims to go a step farther and if but little has been

188 GEO. H. HORN, M. D.

accomplished, it is hoped that discussion will clear up much of the
obscurity and bring some order from the existing chaos.

All of Lacordaire's tribes will be found to have been reviewed, and
from among the genera I have endeavored to select for special study
those about which he or others appeared to be in greatest doubt. The
judgment on the choice of genera must be left to the criticism of all
who choose to find out which they are by a perusal of the preceding
pages or a reference to the index.

That section of the genus Oi/chrus known as Sphaeroderus has been
supposed to be peculiar to the eastern portion of the Atlantic region,
no species having heretofore been found west of the Mississippi River.
Within a few days a species has been received from Washington
Territory. I give the description here as an interesting contribution
to geographical distribution.

Cji'ClirilS {Sphccroderas) relictllK n. sp. — Fditii ^^lender. black, sliining.
Head smooth.' Thorax cordiform, one-fourth broader than long, sides arcuate in
front, oblique behind, base not broader than apex and one-third shorter than the
length, hind angles slightly obtuse, margin very narrowly reflexed, apical arcuate
line and basal transverse line moderately deeply impressed, median line less
deeply, the intra-angular impressions rather deep and curved in front toward the
median line, disc very little convex, surface smooth, slightly wrinkled posteriorly.
Elytra very regularly elliptical, twice as wide at middle as the thorax and a. little
more than one-half longer than their width, margin very narrowly retlexed,
surface with a slight violet tinge with numerous rows of moderately deeply im-
pressed punctures, the striise irregular. Body beneath smooth, shining. Length
.68 inch; 17 mm.

This species is more elongate than any of our eastern SjJinei-oderus,
and differs also in the absence of any punctuation at the base of the
thorax and by the sculpture of the elytra. The legs are also more
slender and longer thaq in the other species. The general aspect of the
insect is that of a Sphaerodei'us imitating Cijchrus strlatopunctdtua.
One male collected at Spokane, Wash. Terr, by Mr. L. E. Ricksecker.

To the Clivin;i3 belongs the European genus Realiela Saulcy, re-
markable as the only known member of the Carabinte with the eyes
so reduced as to be with difficulty observed. The species is extremely
small (.00 inch) even for a member of the tribe to which it belongs.
Synonymous with this genus is Spelseodj/tes Mill. A figure of R. luci-
fuga is given by Saulcy, Ann. Ent. Soc. Fr. 1862, pi. viii, fig. 5, from
which it seems allied to Olivlna rather than Di/schiriiix.

AMERICAN COLEOPTERA. 189

In the Bullet. Ent. Soc. Fr. 1881, No. 17, p. U8, M. Abeille de
Perrin presents a good argument for the union of Trechus and Anoph-
thalmus. The series of species in our fauna is too small for me to
express any opinion, but from the ability shown by M. Abeille in more
difficult observations I have no doubt he is entirely correct.

While I would be willing to accept the idea above indicated I am
not prepared to coincide with those who would unite Anillus with
Bembidium on the ground that these bear the same relation to each
other that Trechus and Anophthalmus do. Through the kindness of
Dr. Dohrn I have been enabled to study iScotodipnua ( Microtyphlus),
and as it did not appear to present anything of special moment for
a general essay, its closer examination w;is deferred until the present
time. The upper surface presents no peculiarities of moment except
that I do not find the elytra truncate as stated by Linder, (Ann. Ent.
Soc. Fr. 1863, p. 483, pi. ix, fig. 7). The u.sual setae of the Bembidiini
are present and that on the mandible well marked. On examining the
under side, which I had omitted to do at first, I was surprised to find
the' posterior cozee rather wideli/ separated. In Anillus the same
character exists, while in Anophthalmus the posterior coxae are con-
tiguous as in ordinary Trechus. This structure is certainly a valid
generic difference and whatever course is taken with Anophthalmus
the other two genera must remain. Notwithstanding the small size
of Scotodipnus I have observed the internal elytral plica of the Bem-
bidiini, feeble of course, but quite as distinct as in some Tachtjs.

In my "Synopsis of the Silphidae," i^ Trans. Am. Ent. Soc. 1880),
I have directed attention to the fact that all tlie eyeless genera have the
posterior coxae separated, but I am not able to explain the correlation
of these distant members of the body.

AMERICAN COLEOPTERA. 197

Index to the Coleoptera described by J. L. L.eConte, 91. D.

BY SAMUEL HENSHAW.

The following list prepared at the suggestion of Dr. Horn owes much
of its completeness to the assistance of that gentleman and Dr. LeConte,
both of whom kindly examined the manuscript and have added con-
siderable synonymy as yet unpublished.

To Dr. Sharp of Thornhill, Scotland, I am indebted for a similar
service with the Dytiscidae.

It may be noticed that a number of the names adopted are of
more recent date than those suppressed, (as Evarthrus vagans G-349
= E. Engelmanui 17-228, Anisodactylus similis 14-1 8;> = A. semi-
punctatus G5-83) ; the reason for this is that the retained name is
either more expressive or one that has come into general use, and as
both the retained and suppressed names were proposed by the same
author no favoritism is shown.*

As a rule Catalogue names published without descriptions are not
included.

In order to avoid confusion a list of the species described by Major
J. E. LeConte is appended.

In the following pages the first number after a generic or specific name
refers to the title in the accompanying list, the second the page. When
a species was described under a difterent generic name irom that used
here, the original name follows in brackets.

The types are for the most part in Dr. LeConte's cabinet. When
a name is followed by * the type is with Dr. Horn, when by * * with
Mr. Ulke, other exceptions will be referred to by note.

Nyssoii auriiiotus Say, Bost. Journ. Nat. Hist, i, p. 368.— " Body black,
punctured; head before with a slight yellowish sericeous reflection; mandibles

" Inhabits Indiana."

Not identified. The description given above seems to refer to a much
smaller species than the jireceding {plagutfus). In some respects it
agrees with small specimens of Farunysson texamts, but not sufiiciently
well to render their identity certain, as that species has several jjrominent
characters which Say would scarcely have overlooked.

Two $ specimens from Illinois, closely related to plagiatus, but
smaller (.40 inch), and with a yellowish band at apex of the three basal
segments of the abdomen above, rather widely interrupted in the middle,
that on the first segment much broader than the others, but not dilated
laterally, may belong to this species, or else to sequaiis Patton, should
that prove to be distinct from aurinotux.

ENTOMOLOGICAL SECTION. Vll

Dr. Horn suggested a modification of the table of Clivina whit-h was
originally published by Dr. LeConte in Proc. Acad. 1857, p. 81, and since
somewhat changed by the author in Bull. Brooklyn Ent. Soc. ii, p. 32.

Lateral margin of thorax attaining the basal margin.

Middle tibiae with a spur on outer side near the tip Species 1-8.

Middle tibise without spur Species 9-15.

Lateral margin of thorax not, attaining the base but forming an ante-basal ridge.

Middle tibiae without spur Species 16-21.

Species 1-15 have many dorsal punctures, 16-21 two or none.

Dr. Horn also called attention to the fact that the characters used in
the separation of the genera of the group Clivinae seemed to have very
little value, and those based on the ligula not strictly true. An iiiiportant
difference between Clivina and Dj/schirius seemed to have been entirely
overlooked. In the former genus the terminal joint of the maxillary
palpi does not differ materially in the sexes, while in the latter that of
the male is much more dilated and on the under surface is excavated,
the concavity which is sharply defined is membranous and probably
sensitive. The two genera are thus distinctly separable, while the ligula
and paraglossse do not differ materially in all the genera of Clivintv.

The gToup Scarites is separated from the Clivinas not only by the form
of the antenuiB and mentum. but also in the occurrence of but one supra-
orbital setigerous puncture in the former group and two in the latter.
A fuller discussion of the genera of both these groups, illustrated with
drawings of dissections of the mouth parts, were promised in a UKjre
extended paper which would soon be presented for publication.

Dr. Horn also exhibited two new species of Desmocerus which he
briefly characterized as follows :

D. californicus n. sp. — Black opaque, elytra bluish- or greenish-black, nar-
rowly margined at base and sides with orange-red. Head and thorax densely and
moderately coarsely punctured, the latter with the surface regular, and with a
slight tinge of bluish-green. Elytra densely punctured, the punctures near the
base coarse and deep, becoming gradually finer and denser toward the apex, sur-
face black opaque and with a bluish, violaceous or greenish tinge, the lateral and
basal margins narrowly orange-red, scutellum and a small spot each side black.
Body beneath and legs densely and rather finely j^wnetured, the metasternum
very finely pubescent. Length .64 % —.80 J inch ; 16—20 mm.

The male is smaller and more slender than the female, and the elytra
gradually narrower to apex ; the five basal joints of the antennae are also
stouter and more serrate.

Collected by Mr. H. K. Morrison during the past year, in the southern
part of California.

Vm MONTHLY PROCEEDINGS

D. cribripennis n. sp. — Black, moderately shining, elytra bluish or greenish
more or less metallic, narrowly margined with orange-yellow. Head coarsely and
deeply, more or less continently punctured. Thorax coarsely transversely plicate
by the confluence of the punctures, surface irregular, bronzed. Elytra very coarsely
and deeply punctured, the punctures near the apex very little smaller. Scutellum
and a small sjjot each side black. Body beneath and legs finely and moderately
densely jiunctured, the abtlomen less densely at middle. Length .48 % — .72 9 iuch ;
12—18 mm.

The sexual characters are as in the preceding species but less marked.
Collected by Mr. Morrison in Washington Territory.

Dr. Horn stated that some time ago he exhibited females of these and
supposed them merely instances of dimorphism. He was glad to be able
to correct his own mistake and place the species in their proper light.

Desmocerus now contains four species, three of Avhich belong to the
Pacific fauna, they are as follows :

Elytra at basal half yellow, apex blue, disc finely tricostate, {elongatus BL).

palliatns Forst.
Elytra either entirely yellow or margined with yellow, not costate.

Male elytra orange-yellow, female with discal blue space, i)unctuation moder-
ately coarse, a little finer near apex aureipeiiiiis Chev.

Elytra similarly colored in the sexes, both narrowly margined with yellow at
sides and base.
Thorax irregularly jilicate, elytra coarsely aud deejily punctured from base

to apex cribripennis Horn.

Thorax densely punctured, regularly convex, elytra moderately coarsely i)unc-
tured at base, more finely and densely at apex caliTornicnS Horn.

BV WILLIAM II. ASIIMEAI).

.T;ick.';..nville. Floridii.
[Pai'eu No. L]

Having been engaged during the past winter on a study of the
cynipidous galls of Florida, I propose to give the results of my in-
vestigations in some short papers.

As comparatively little of importance has been published respecting
the galls of the live oak Quercus vh-ens, I make that the subject of my
first contribution :

The (tALLS of the Live Oak, Quercus virens.

Of the many curious galls affecting this tree, the first to which I wish to
call attention is one which may be designated by the popular name of
The Live Onh Pea Gall.

Baron Osten Sacken was the first to give an account of it twenty
years ago in his paper entitled, " On the Cynipidae of the North American

MONTHLY rnoC. ENT. SEC. A. N. S. (2) MAY, 1881.

X MONTHLY PROCEEDINGS

Oaks and their Galls," p. 57, published in the Proc. Entom. Soc. Phila.
1861. He says:

'■'■Quercus virens, Live Oak. — Small, globular galls on the under side
of the leaf. Diam. 0.15 to .2." Pale brownish when ripe; filled inside
with a spongy, cellular mass, which is more dense than that of the pre-
ceding {C. conJiue7is), and not unlike the pith of a reed in texture.
Single kernel in the centre.

" I am indebted for these pretty galls to Dr. Foreman, who brought
them from Greorgia, and although I do not know the fly, I have no doubt,
from the structure of the gall that it is the produce of a C^nips."

In this supposition my researches prove him to be correct. Early
this winter, I procured specimens of this gall from a tree, the leaves of
which were literally covered with them, and from which I have bred the
gall-fly and its parasites, the latter will be described in a future paper.

Cynips q. virens n. sp.

Galls. — Small, globular, the size of a pea or slightly larger ; from two
to ten, attached to the under side of the leaf; pale brownish in color,
filled inside with a dense, yellowish-brown, spongy, cellular mass. A single
kernel in the centre. Diameter 0.15 to 0.25 inch.

Gall-Fly. — 9 • — Length .15 inch. Head reddish-brown, finely punctate, pubes-
cent; mandibles black; antennae 13-jointed, reddish-brown, first two joints some-
what fulvous, nearly connate, third longest, about five times as long as second,
following joints gradually decreasing in size, excepting thirteenth which is slightly
longer than twelfth and infuseated; thorax brown, coarsely punctate, pubescent;
parapsidal grooves distinct, two longitudinal grooves on preescutellum blackish ;
scutellum round very finely rugoso-punetate, pubescent; wings hyaline and re-
markably long, veins brownish and thick, radial area almost closed, areolet distinct,
petiolated, abdomen dark reddish-brown, all segments visible, basal half of second
light reddish ; legs light reddish-brown, posterior femora slightly infuseated.

Described from one bred specimen. Although I have nearly two
hundred specimens of the galls in boxes, I have raised but a single
Ci/iiips, and that issued from the gall early in February.

The Live Oak Potato Gall.

By the above name I designate a gall which is found quite abundantly
on the twigs and branches. It is evidently the same mentioned by
Baron Osten Sacken (loc. cit. p. 259, 1862-). He says:

"Quercus vlrens, Live Oak. — Woody swellings on the limb. The
specimen communicated by Mr. Grlover is _a fragment of a branch about
one and one-half inches long, with two such swellings ; the one is rounded
about 0.7 long and 0.5 broad ; the other much smaller. I opened the
latter and found on the inside a small hollow from the structure of which
I have no doubt that the gall is the produce of a Oj/nips."

ENTOMOLOGICAL SECTION. XI

I obtained specimens of this gall early in January and February, and
have succeeded in raising several of the flies. Many of these galls are
picked by birds and gnawed by mice ; both of which evidently highly
esteem the rich, juicy morsel within.

Cynips q. batatoides n. sp.

Galh. — Abrupt, potato-like, irregular swellings of the twigs and
branches, varying in size and form, from 0.4 to 0.7 and sometimes an
inch long, and 0.3 to half an inch or more broad ; the outer surface is
rough of the same color i^s the bark ; internally it is white and in con-
sistency not unlike a potato. No kernels; each insect separated by a
very thin, hardly perceptible parchment-like substance. In one of the
galls I counted fifteen gall-flies.

Gall-Fly.— 9 .—Length .12 inch. Head brownish-red, finely punctate, slightly
pubescent, mandibles bidentate, tips black; palpi yellowish ; antennse 15-jointed,
reddish-brown, joint third not quite thrice as long as first and second combined,
joints four to eight subequal, nine to fifteen about equal, terminal joint smallest;
thorax more coarsely punctate, brownish-red, covered with fine, short, whitish
pubescence, parapsidal grooves indistinct, two longitudinal grooves; seutelluni
rugoso-punctate, slightly ridged, ridge more perceptible anteriorly and blackish ;
wings hyaline, veins black, radial area open, areolet distinct, petiolated ; abdomen
smooth and polished, of a uniform reddisli-brown ; legs yellowish or yellowish-red,
thighs, coxfe and trochanters darker, feet black.

Described from numerous bred specimens all females.

The structural characters of this species indicate the possibility of its
belonging to Giraud's genus Dn/cosmus, as defined by Baron Osten
Sacken, (loc. cit. 4th article, p. 337).

The Bud-like Gall of the Live Onk.
This gall seems to have been entirely overlooked by all observers ; it is
difficult to see why, for although not nearly so plentiful as the previously
described species, it is yet by no means rare and quite noticeable upon
the ends of the twigs.

Cyni|>!>i q. >*ucciiii|>es» n. sp.

G^a//.s-.— Clusters of from five to twenty small galls crowded around
a terminal twig or branch; globular, or bud-like in form; externally

outer ocelli, parapsidal grooves distinct, brownish-black, two small grooves be-
tween these and just back of the black vittse, converging towards scutellum not
quite reaching hinder edge; the grooves are blackish and also the surface of the
mesothorax a short distance along their edge ; scutellum roundish, punctate and
pubescent ; wings hyaline, veins brownish all strongly defined, radial area nearly
closed, areolet closed, the closing vein very pale,- legs a clear amber pubescent;
abdomen dark brown, smooth and shining basal part of the second segment
reddish.

Described from one bred specimen.

Thr Leafy Gall of (he Live Oak.

Another curious and by far the most interesting gall I have yet found
in Florida, is that to which I have given the above name. Growing as
it does in the bud axil of the leaf, and not unfrequently iu close proximity
to the others, the gall would naturally be taken by most observers for
the blossom of the oak ; indeed I never until lately suspected it to be
the product of a Ct/nips.

On page 72, vol. 2, of " The American Entomologist," is figured a gall
discovered by II. F. Bassett, so well known for his researches in this
interesting branch of entomology, which will give one a fair idea of the
species under consideration.

At first I was inclined to believe my species and his, which he calls
Cj/nlps frondom identical; but on a careful study of his description of
the gall, (he does not characterize the insect producing it), I have no
hesitancy in describing it as new.

Mr. Bassett found his species at Watcrbury, Conn., on the Chincjuapin
Oak, Q. prlnoldeSj while Walsh found it on the Bur Oak and White
Oak; vide Proc. Entom. Soc. Phil. p. G8, 18G4-.

He says : " When mature it often attains a diameter of two and a
quarter inches, and the modified leaves of which it is composed are then
much longer and proportionally much wider than at first, so that instead
of being what the botanists term ' lanceolate,' they become oval with
their tips usually acute."

Bassett says : " The cells containing the larva are smooth, shining,
oval, about one-eighth of an inch long."

Walsh also says : " The larger ones enclose four or five cells and when
the gall becomes mature, the cells are gradually disengaged from their
leafy matrix and drop to the ground, where no doubt the larva will pass
the winter more agreeably among the masses of dead leaves, which
accumulate in such situations, than it would do if it were exposed aloft
to the stormy blasts, and the cold driving sleets of the dead season of
the year." ,

ENTOMOLOGICAL SECTION. XUl

Now, the largest specimen I have ever found of the present gall, and
I have collected hundreds, is never more than three-quarters of an inch
in diameter, and instead of the leaves being oval, they are strictly
lanceolate ; the cells or kernels too, instead of being smooth, are pitted,
somewhat like a peach stone. They likewise never drop to the ground,
but remain cemented to their cup, and the fly escapes by pei'forating
a hole in the top. I have found hundreds of the black dry galls
containing cells so perforated, and have never seen more than one cell
to a gall.

Cynips q. foliata n. sp.

Galls. — In outline urn-shaped, composed externally of numerous,
lanceolate, leafy-like spines, developed from the axillary leaf bud ; dia-
meter one-half to three-quarters of an inch ; internally consisting of a
greyi.sh acorn-lfke cup, with a single kernel imbeded half way ; cup
.20 inch in diameter. Kernel brownish .15 to .18 inch long by .07 to
.10 wide, somewhat pointed at top and slightly contracted in the middle?
iiTcgularly pitted and grooved, somewhat like a peach stone only the
grooves arc not so deep.

Gall-Fly.— $> . — Length .12 of an inch. Head brown, face to mandibles covered
with rather short, thick, white pubescence, a series of grooves or acieuUitions
converging towards mandibles, the latter black vertex rugoso-punctate, free from
pubescence, palpi yellowish, terminal joint slightly infuscated at tip ; antennre
1.3-jointed, brownish-red, third joint twice as long as second, others to tenth sub-
equal, tenth, eleventh and twelfth very short, about equal, thirteenth not quite
twice as long as twelfth ; mesothorax and seutellum reddish-brown, rugoso-punc-
tate, covered with short whitish pubescence, parapsidal grooves distinct, brownish,
two short subdorsal grooves starting from collare and extending backwards not
quite to middle of thorax ; abdomen smooth, bright, shining reddish-brown ; legs
yellowish-red, feet and coxse brownish or blackish; wings hyaline, veins yellow-
ish, radial area open, areolet none.

Described from numerous bred specimens.

The Live Oak Woolij Gall.
This unique and beautiful little species approaches nearest to the one
described by Dr. Fitch, (see Ann. Report N. Y. State Agi-i. Soc. Fifth
Report, p. 814), under the name of C. q. lana, readily distinguished from
it, however, by size, coloration and in having but 14-jointed antennae.

Cynips q. lanigera n. sp.

Gall. — Small, flattened, circular or in-egular tufts of rather long
whitish or ferruginous wool, on the under parts of the leaf; attached
generally to the principal vein and covering from two to six small,
irregvilar, smooth brownish seed-like kernels, .06 to .08 inch in diameter.

The Publication Committee laid upon the table (pages 33 — 48) of
volume ix, of the Transactions of the American Entomological Society,
printed since the last meeting.

The Publication Committee reported that work had been resumed on
the Transactions and Proceedings. A new press of a much improved
model had been procured, and while the impression consisted of but two
pages the work can be more expeditiously and cheaply done than by the
old press. The same standard of good presswork will be maintained and
the reputation which our publications have attained as one of the best
printed scientific serials, will still continue.

ENTOMOLOGICAL SECTION. XV

The old press is broken in such a manner as to render its repair more
costly than the Committee at first realized and it was resolved to
abandon it entirely. This old press has now been in use about nineteen
years, doing all the work on five volumes of the Proceedings and eight
of the Transactions and two of the Practical Entomologist, beside much
other miscellaneous entomological printing.

It was the gift of Dr. Thomas B. Wilson, and with the full supply of
type the Committee have been enabled to continue to the present year
without either much repair to press or renewal of type. Our present
volume (vol. ix), however, begins with an almost entirely new supply
of type.

The Committee hope to complete a volume with the present year,
with at least three hundred pages, and from the information in our
possession the number of plates will be a.s great or greater than in
any preceding volume.

The GrALLS op the Willow Oak, Quercus hnu-ifnllse.
TliLs particular species of oak is classified by botanists as a variety of
Quercus jjhel/os, and from it I have obtained nine distinct species of galls.

The Cherry Stone Leaf Gall.

This popularly designates a. unique gall that appears early in February
and March, on the tender new leaves — fref(uently three on a leaf. It may
possibly be the one referred to by Prof. Westwood as described by Bosc,
from Georgia, vide Intro. Entom. vol. 2, p. 181, ed. 1840. He says:

" Another gall of the size of a pea, found on another species of oak
has the outer surface very thin, and encloses in the interior a small ball
the size of a grain of millet which rolls about, and within which the
larva is lodged. M. Bosc opened hundreds of these galls without being
able to learn the true nature of this production."

Baron Osten Sacken, loc. cit. p. 62, discovered a similar gall Cynips q.
palustris on Quercus palustris. My species is at once distinguished from
it by having 14-jointed antennae in '^ , va. punctation, coloration, by the
veins of wings being black, and by the long bent peduncle in the % .
It evidently belongs to Hartig's genus Spathegaster.

Spathegaster q. laiirifolise n. sp.

Galls. — Green, globular, hollow galls, growing through the leafy
expansion of the newly formed leaf, projecting about equally from the
upper and on the under surface of the leaf, the size of a cherry stone
and when removed not unlike it in shape, containing a yellowish, slightly
elongated kernel, which rolls freely about. Length .20 to .25 inch,
.15 or more through.

wings very long reaching way beyond tip of abdomen ; abdomen small triangular,
compressed, with a very long peduncle, slightly bent downwards before the middle ;
otherwise as in lemale.

Described from over one hundred specimens bred in March.

On a % cynips, cUnging to the long curved peduncle, I detected a
curious gamasid mite but 0.2 mm. long. It was of a reddish-brown
color, oval, coriaceous and pubescent ; with eight remarkably long hairy
legs, the posterior pair being longest, and the cephalothorax separated
from the abdomen by a transverse suture and with the head rather
pointed. It evidently belongs. to the genus Sejiix and may be known as
Scjus ci/nipufis.

Another curious gall, constructed on the same principle as above but
smaller and not projecting through the leaf, was detected the middle
of April.

Cynips q. confiisa n. sp.

Galls. — Small, globular, slightly elongate, greenish-yellow, succulent
galls, . attached to the principal vein on the under surface of the leaf,
hollow inside with a pupa-like kernel ; fly escaping by perforating a
hole through the upper surface of the leaf. Diameter transversely .06 ;
vertically .10 inch.

antennae reddish-yellow. 14-jointed, third joint longest, joints to eighth subequal,
others short and equal, terminal twice as long as penultimate; thorax rugoso-
punctate, parapsidal grooves distinct, two longitudinal grooves converging pos-
teriorly; scutellum deeply rugoso-punctate, slightly elevated posteriorly and de-
pressed and with a large deep fovea at base, not pubescent ; pleurae deeply aciculate ;
wings hyaline, veins reddish-brown, areolet nearly closed, radial area open;
abdomen black and highly polished, last ventral valve projecting ; legs reddish-
yellow, coxfe black.

Described from 2 9 specimens bred the last of April.

Another gall found on the under surface of the leaves, produces a
very roughly punctured cynips which may be known as

Cynsps q. riigosa n. sp.

Gdi/s. — Semispherical, greenish-yellow, smooth, hard galls, attached to
the under surface of the leaf, slightly contracting the leaf on the upper
surface, but not projecting, either flat or slightly concave ; internally
consisting of a hard fibrous substance in the centre of which the larva
is transversely placed ; fly escaping by perforating a hole through the
upper surfiice of the leaf. Diameter transversely .20 inch ; through or
vertically .08 to .10.

The Galls op the Upland Willow Oak, Querent dnerea.
There are several galls found on this tree, but by fir the most import-
ant is a large spherical gall, which may popularly be termed

The Up/and Wi/foiv Oak Apple Gall.
Cyiiips q. ciiierea n. sp.

Galls. — Large, perfectly spherical galls attached to the twigs and
limbs, of a dark crimson color mottled with small spots of a lighter
color. A single kernel in the centre held in place by dense, brown-
ish, spongy filaments. Diameter one and one-fourth to one and one-
half inch.

Gail-Fly. — J . — Length .20 inch. Rf)bust .07 inch across the mesothorax, length
of wing .20 inch. Head and thorax brown, deeply, very coarsely rugoso-punctate.
Head. small, on vertex slightly pubescent, thicker back of the eyes, almost free on
face; eyes dark brown ; mandibles black; antennae 1.3-jointed, short not reaching
to back of scutellum : thorax broad, robust, convex, parapsidal grooves almost
obsolete, longitudinal furrows wide apart and almost parallel, indicuited by coarse
punctures, a deep transverse furrow dividing mesothorax from scutellura, a few
microscopical whitish pubescence towards head, disk free; scutellum round, ele-
vated, deeply irregularly rugoso-punctate, free from pubescence, excej^ting a few
microscopical whitish hairs more perceptible at posterior margin, two deep round
foveae not quite separated by the pointed process of the scutellum, which does not
reach the margin, pleurae rugoso-punctate, pubescent, as well as the triangular
piece beneath the wing and the metathorax ; abdomen bright, smooth, reddish-
brown, globular and regularly rounded posteriorly, a high ridge at base of second
segment, slightly pubescent, more noticeable at sides and beneath, a high power

the whole length ; wings hyaline, rather hairy, veins reddish, areolet closed, radial
area open, a large brown blotch occui^ying basal half of radial area and apical
third of areolet, also extending slightly along the cubitus ; basal vein thick and
clouded with brown; anal vein brown from opposite tip of areolet; tip of radial
vein pale, subcostal vein becomes brown as it approaches basal vein and be-
comes pale again just before joining the large brown blotch; legs reddish-brown,
pubescent.

This no doubt will prove to be related to the dimorphic group of
Ci/nips — spang ijica, aciculata, etc.

I noticed smaller galls on the trees during the winter, but all
were empty and have produced nothing but Chalcid flies — CaUimeme,
Pteromalus, &c.

The summer galls will probably produce the two gendered form.

The Publication Committee laid upon the table pages 49 — 64 of

volume ix of the Transactions of the American Entomological Society,

and also pages ix — xx of the l^roceedings of the Section, printed since

the last meeting.

Dr. LeConte desired to record the following notes of synonyms and
habits of Coleoptera.

Cicindela Sommeri Mannh. — This common Mexican species was found
by Mr. H. Edwards, at San Diego, Cala.

Carabus truncaticollis Eschsch. — Occurs in the higher parts of the
Sierra Nevada, Cala., (II. Edwards).

Axinopalpus Lee. — Ann. Lye. Nat. Hist. N. Y. v, 174, (1846), has
priority over Varlopalpus Sol., Gray, Chili, iv, 148, (1849). The con-
fusion in this synonym has been produced by a typographical error in
the INIunich Catalogue, in which the date attributed to my genus is
printed 1851 instead of 1846. The verbal expansion of the name to
Axinopselaphus seems unnecessary and scholastic.

Patrohus ruglcollia Randall. — Telluride, Ouray Co., Colo. ; (ll^inecke).
The western extension of this species is quite unexpected.

Agyrtes longulus Lee, has been found in Maryland by Mr. Hike.
Previously known only from the Pacific coast.

Platycerus Agnssii. — I have seen (juite a large number of specimens
of this species, but have not observed any sexual characters worthy of
note. Mr. Edwards has kindly given me a specimen, which by the greater
length of the antennal lamelhr) is evidently a S . . The ninth and tenth
joints of the antennae are more than twice wider than long ; the mandibles
are slightly more prominent ; the legs are longer and thinner ; the tibia)
are less strongly toothed and the tarsi are as long as the tibisc, while in
the 9 they are about one-third shorter. The prothorax is less dilated
on the sides and less constricted at the base than in the 9 •

Gyascutus Lee, seems hardly sufficiently distinct from Latipalpis Sol.,
to be worthy of retention as a separate genus.

Pterotus obscuripennis Lee. — Flying at dusk. Berkeley, Cal. ; (Rivers).

Cyllene picta. — An enormous number of individuals of this species
were developed from a pile of hickory wood in the cellar of a friend in
this city, in the latter part of April and beginning of May. The sawdust
from the burrows in the wood might be measured by bushels, while the
perfect insects invaded all parts of the house, becoming a great nuisance.

Luperus varipes Lee. — Berkeley, Gala. ; on Teucrium ; (Rivers).

Dr. LeConte also mentioned an extraordinary change of color dependent
on emotion or nervous excitement, which he had observed in some living
specimens of Coptocycla aurichakea, which he had recently received from
Dr. M. Groldsmith, Rutland, Vt., by whom they were found perforating
holes in the leaves of Ipomaea. The specimens not only varied greatly
in color, some having the elytral disc black with golden spots, while in
others (var. pallida), the whole disc was golden, but when frightened,
the gold color disappeared completely, and the insects assumed the same
dull reddish-yellow which they have when preserved in collections. In
recovering their metallic color they passed through various grades of
bluish-pearl and violet, until they again became bright golden. This
phenomenon, which so far as Dr. LeConte knew, had not been hereto-
fore recorded, and to which his attention has been called by Dr. Gold-
smith, is a very singular one, and deserves the careful observation of
microscopists.

Dr. Goldsmith has also observed that the difference between these two
reputed distinct species is sexual, the guttata form having a black disc
with golden spots being the S , very similar to C guttata.

He placed one of the spotted individuals under a glass with two of
those having a uniformly disc. After a short time amatory relations
were established between the former and one of the latter. What
occurred subsequently is thus narrated :

" Mr. spotted-hack forthwith became of a greenish-gold, and Mrs.
pallida a yellowish-gold. The other Miss lost her beauty and became
the dingy thing she is on wash days. I uncovered the vessel and some-
what rudely disturbed their beatitude, and immediately Mr. and Mrs.
both assumed their ordinary wash day clothes. The fact is, gold and
jet are the colors of the male when undisturbed, greenish-gold in
copula, and dingy when disturbed. Both when recovering from fright
become at first a beautiful glistening purplish mother-of-pearl, then the
male gold and jet, and the female gold."

These interesting observations may serve to diminish the very large
number of nominal species in the books.

ENTOMOLOGICAL SECTION. XXIU

Dr. Horn exhibited the drawings which form the eight plates to
accompany the paper presented for publication. Special attention was
called to those figures which illustrate the definition of the families
composing the Adephagous series of Coleoptera, a discussion of this
matter being necessary before a consideration of the Carabidae. This,
Dr. Horn said, was necessary in consequence of the diverse opinions ex-
pressed by various authors concerning Amphizoa, PeloUus and Haliplus.
By well defined structural characters not hitherto observed it was shown
that these are really types of distinct families equivalent to the Carabidse
or Dytiscidfe. Dr. Sharp in a late paper had included Amj^hizoa and
PehbiuH in the Dytiscidfe while Chaudoir's latest opinion was in favor
of retaining the former in the Carabidae.

Dr. Horn stated that he regretted to differ so completely with such
eminent authority, but the characters in which these genera differ from
all others of the Adephagous series are of such an important nature that
he insisted on maintaining the view originally expressed by Dr. Leconte
of the position of Amphizoa.

Attention was also directed to two finished plates illustrating genera of
the Serricorn series, the text being nearly completed by our printer.

Dr. Horn announced the decease of Baron de Chaudoir, an eminent
Coleopterist of Europe and a corresponding member of the American
Entomological Society.

On the CYIVIPIDOUS GAL.LS of Florida.

BY WILLIAM II. ASHMEAD.

Jacksonville, Florida.
[Paper No. 3.]

The Live Oak Root Gall.

This interesting gall was discovered the latter part of March. A work-
man ploughing around a live oak, Quercus virens, noticed some curious
galls on the roots and called my attention to them. A careful search
soon revealed great quantities, always on the small rootlets running along
just beneath the surface. On pulling up these roots, I discovered a series
of gall clusters every four or five inches apart, and have bred from them
nearly two hundred specimens, % and 9 Ai^s. These are the first
authentic oak root galls discovered in the United States.

BiorrMza niger^ Fitch, discovered on snow probably produces galls
on oak roots ; but the galls have not yet been found. <

ENTOMOLOGICAL SECTION. XXV

As my species presents characters widely diiFerent from any cynipidous
genera known, I propose to erect a new genus for its reception. Like
Biorrhiza niger, it secretes, when handled, a strong waspy odor.

DRYORHIZOXENUS n. g.

Form slender ; maxillary palpi ^-jointed, labial palpi '^-jointed, the third joint
globular ; mandibles tridentate, outer two teeth acute, inner one obtuse ; areolet
closed, radial area open, radial vein regularly curving upwards and thickening
at tip.

9 . — Antennse 14-jointed, filiform, pubescent, first joint stout, attached to the
head by a short peduncle, second small, moniliform, third longest, slightly curved
and excised, thickest at tip, the following subequal in length, uniform in thick-
ness, terminal joint longer than penultimate, all the joints from the fourth have
a narrow bead-like annulus at tip, quite noticeable in living, almost obsolete in dry

%. — Antennse 15-jointed, filiform, second joint small, slightly elongated, third
longer than in 9 > excised, each joint widening and truncate at tip and without
the bead-like annulus. Abdomen long-ovate, attached by a short peduncle, front
tibipe frequently unarmed ; otherwise as J •

l>ryorIiizoxeniis floridaniis n. sp.

Galls. — Clusters of irregular somewhat wedge-shaped, soft, fleshy
galls, of the consistency of a potato, surrounding the rootlets of Quercus
vlrens^ brittle and easily detached, varying in length from one-half to
three-fourths of an inch ; externally rough, irregular, and of a yellowish
color ; internally composed of numerous cells one above another, and
separated by thick fleshy partitions.

Gall-Fly. — 9- — Length .20 inch. Slender; bright shining brownish-yellow;
head finely punctate, eyes, tips of mandibles and ocelli black; antennte brown,
basal joint paler; thorax convex, smooth and shining, two deep longitudinal
grooves converging towards scutellum, which is coarsely rugoso-punctate and
slightly pubescent, posterior margin dark brown; abdomen smooth and shining;
legs brownish-yellow, densely hirsute; wings hyaline, areolet closed, petiolate,
radial area open, all the veins dark brown and bordered with brown, the brown
border widening at tip of subcostal and radial veins, the blotch not quite reaching
outer edge, the anal vein rather straight and thick, broken opposite middle of
areolet, the brown border surrounding the broken part and extending along to
near the tip of the vein.

tarsi less densely hii-sute, black and with the tibial spines less strongly developed
than in J ; abdomen elongate-ovate, smooth and shining, second segment occupy-
ing half the surface, other segments gradually decreasing in size; otherwise
as in 9 •

Described from nearly two hundred bred specimens. The fleshy galls,
when dry, are almost unrecognizable from the shrinkage in drying.

The Grape-producing Cynips.

This is a very remarkable Cynips producing galls on the under surface
of the leaves of Quercus laurifolia, which very much resemble small
white grapes. They make their appearance early in April, but the flies
do not escape until the middle of May.
Cynips q. raceinaria n. sp.

Galls. — Spherical, crisp, sour and succulent, attached to the under
surface of the leaves, in size and color resembling a small white grape
and in consistency not unlike a green gooseberry, with a single reddish
kernel in the centre. Diameter .35 to .40 inch

Gall-Fly. — 9- — Length .16 to .17 inch. Black; head rather small, deeply
rugoso-punctate, vertex free from pubescence, a tuft of long pubescence back of
eyes, face very slightly pubescent; antennte 14-jointed, black and short, only
reaching to tip of scutellum, third joint longest, fourth to eighth subequal, the
others equal, terminal slightly longer than penultimate; thorax deeply coarsely
and irregularly punctate, almost free from pubescence, requiring a high power to
detect any ; pleurse less deeply and coarsely punctate ; abdomen large, black and
shining, apical half of second segment, and all the other segments excepting at
base, finely and densely punctate, a few hairs on second segment, ventral sheath
very long; legs reddish-brown, pubescent, coxse and trochanters black, apical
spurs on all legs; wings smoky or brownish-black, apices slightly paler, veins
black, areolet closed, radial area open, rather narrow.

Described from numerous bred specimens which hatched in May.
No males.

The only other grape-like gall known to me is Cynips q. sculptus
Bassett, described in Proc. Entom. Soc. Phila. 1863, p. 324. The
present species is at once distinguished from it by its smaller size, short
14-jointed antenna3, the difiierence in shape of joints, color of legs and
by the punctation of abdomen.

Cynips q. sculptus is 9 .20 inch, antennte 13-jointed very long, legs
honey yellow, abdomen entire surface microscopically punctate. It was
found by Mr. Bassett on Quercus rubra.

The Spine-bearing Potato Gall.

Another potato gall, varying greatly in size, found on the terminal

twigs of Quercus laurifolia. It very much resembles the live oak

potato gall, Cynips q. batatoides nob. ; but is easily distinguished from

it and all others by the spiny, succulent tubes which issue from the

ENTOMOLOGICAL SECTION. XXVU

fleshy part of the gall. These often become quite large, but are
generally eaten by birds, or become broken ofi" by the swaying of the
branch in the storms and winds. As they mature the galls become
irregular, crack and turn black with age, ultimately killing the twig
upon which they are situated. At this stage there is a small black ant
that gnaws into and makes it the abode of her countless progeny.

Cyiiips q. clavigera n. sp.

Galls. — Abrupt, irregular, woody, tuber-like swellings, varying greatly
in size, from a half to an inch and a quarter long by almost the same in
width, attached to the terminal twigs and branches; externally (at the
beginning of the season), it is smooth and resembles very much the gall
of Cynips q hatatoides, but later in the season it becomes rough with
deep fissures, through which issue spiny, succulent tubes, which secrete
a sticky honey-like substance ; internally, at first it is white and soft but
becomes brown and hard with age ; the tubes are thickened at base in
the centre of which the larva resides.

Gail-Fly. — 9 • — Length .08 inch. Reddish-brown ; head and thorax very finely
punctate, face slightly aciculate, converging towards mouth; antennje long, 15-
jointed, first joint as long or almost as long as third, second globular, slightly
longer than wide, joints four to eight subequal, from nine to fourteen short, equal,
apical smallest; thorax, parapsidal grooves distinct, two longitudinal furrows
converging towards scutellum ; pleurse punctate ; scutellura finely rugoso-punctate
and bifoveolate ; abdomen brownish-black on dorsum, reddish-brown beneath,
smooth and shining and of a very peculiar shape; viewed from above it is as
usual, but viewed sideways it is much deeper than long, with the ovipositor pro-
jecting at an angle of forty-five degrees; with a quarter inch glass the segments
show that they are finely microscopically punctate; wings hyaline, veins yel-
lowish, areolet closed, the closing vein being faint and nearly hyaline, radial vein
and subcostal extend to costal edge but the subcostal does not extend along the
margin to radial vein, hence is open ; legs reddish-brown.

Described from" one specimen taken from gall May 3d.

The Gone Gall.

A black or brownish-black conical gall, issuing from the bud axils
of the larger branches of Quercus laurifolia and Q. phellos, was dis-
covered early in April. They present a very anomalous appearance on
the branch.

From numerous specimens gathered early in the season, I have bred
many parasites, principally Figifes, but no Ci/nips, and my description is

Studies on the North Ainericstu C'IIAL.€ID1D.£. with «Ie-
sci'iptioiis of New Species froiu Florida.

BY WILLIAM H. ASH MEAD.

Jacksonville, Florida.
[Pai-ku No. 1.]

The following is the beginning of a series of papers on our North
American Chalcididse — a large and extensive family of parasitic hymen-
opterous insects comprising the minute forms, which are, however,
readily distinguished from all others by their elbowed antennae and
almost veinless wings.

Although they are among the most interesting and brilliantly colored
of the order Hymenoptera ; yet up to the present time, when we take
into consideration the extent of our continent, comparatively few species
have been described.

These studies are not intended to bo exhau.'^tive but merely pre-
liminary— i. e., an attempt to ascertain and group together all that has
been written on the subject, and at the same time describe the new forms
brought under my observation in Florida.

The species belonging to the genera Leucospis, Smin-a and (^halcis,
have been exhaustively treated by our well known Hymenopterist
Mr. E. T. Cresson, in a memoir published in Vol. IV, Trans. Amer.
Ent. Soc. 1872. I have, therefore, only to record the new species
since its publication.

wings fusoo-liyaline with a small black stigmal dot, and with the last two-thirds
of the outer costal edge black, other veins brownish ; legs yellowish, anterior and
middle femora infuscated in middle, the thick oval posterior femora yellowish-
brown, a broad dark medio band occupying one-third or more of the surface, the
band is also extended over on to the tibire as may be seen when these are drawn
up into the femoral groove, the latter armed with about eighteen small but regular
teeth, tarsi pale yellowish, ungues black.

Captured on rose galls. I do not think it parasitic on the galls ;
it was probably attracted there by some larvte.

Eurytoina priiiiicola Walsh, loc. cit. fig. 1.

This species I have bred from the cynipidous oak gall ('. q. riigosa
Ashmead. It agrees very well with Walsh's description excepting its
larger size and the whole abdomen being black. He says : " $ with the
bng medial or fifth joint always rufous and the fourth generally piceous."
I am therefore in doubt whether the determination is correct.

Walsh was unable to identify this species and seemed to think the
"laws of coloration forbid its existence." Neither Walsh's want of suc-
cess in finding it, nor are the laws of coloration sufficiently demonstrated,
to warrant its rejection.

Callimon.e rece.nareie n. sp.- ?. -Length .18 to .20; ovip. .28 incl> j..
This species in color and markings resembles C. c<.rulea very much
and for a long time I was of the opinion that they were identical.
A more careful examination soon dispelled the illusion. It may be
easily distinguished by a more slender form, by punctation being more
coarsely punctured than ccerulea, by the face being covered by a dense
silky pubescence, by the antenna being brownish, scape a-eddish by
the much Jonger ovipositor, and by the yellowish-red pubescent legs.
In coerulea the legs are not pubescent.

The % is .IG inch in length, and is difficult to distinguish from ^ ot
ccerulea. It may be distinguished however by the scutellum bemg
divided in the middle by a tran.sverse suture, by all the femora being
blue exceptins at tips and by a darker abdomen.

The Publication Committee announced the completion of the Trans-
actions of the Americau Entomological Society to page 148.

In behalf of Mr. Ashmead, Dr. Horn presented types of nearly all
the species described in the paper jjresented at the last meeting, for the
cabinet of the American Entomological Society.

Dr. McCook exhibiti'd some small Hymenoptera hatched from the
nests of Mud-Wasps. He also placc^d bc^fore the meeting the nests and
cocoons of some sjtiders. showing the means made use of for their
protection and concealment.

Dr. Horn exhibited a new Ci/chrus from Washington Territory, be-
longing to the .sub-genus Sphseroclerm, this being the first known
occurrence of the latter west of the Mississippi.

A female Xenorhipis was also shown. This has the antennjie not
very different from Melanophila or Ayrilus while the male antennae
are flabellate.

Dr. LeConte gave his views regarding the dispersion of Coleoptera
in times following the glacial epoch. At the time when the present
circampolar i-egions were much warmer than now and the continents
probably less separated or even joined, the fauna was perhaps the same
in the entire region. The glacial invasion extended .farther south in
the Atlantic region than in the Pacific, obliterating in great part the
Coleoptera of this side of the continent while the Pacific slope was
less disturbed. Consequently the species of the latter region being the

XXXVl MONTHLY PROCEEDINGS

descendants of the circumpolar fauna, a notable resemblance is observed
with, their descendants in the European fauna. Our Atlantic region was
probably replenished by an invasion of species from the south.

Dr. McCook spoke of the effect of the cold of last winter in extermi-
nating the spiders in various neighborhoods, notably near Washington.

Dr. LeConte read the following notes on the habits and localities
of Coleoptera.

Cicindela pamphUa. — Corpus Christi. Texas; (Mische).

Fhytonomns punctatus. — This ct)mmon Euro})ean species has been
noted by Mr. Eiley as depredating on clover, in Yates Co., N. Y.
P. opimus Lee, founded on an old and someAvhat rubbed specilnen is
referable to the same species, and shows that it is not a recent importa-
tion to this country. The specimen in (jue.stiou was given me by
Dr. Melsheimer about twenty-five or thirty years ago and was then old.
A similar specimen was not long afterwards sent to me from Canada.
Some peculiar circumstances have probably in this, as in many other
instances already recorded, favored the development of this insect in
Yates Co. to i*uch an extent as to make it injurious.

the Transactions of the American Entomological Society to page 212.

Mr. E. T. Cresson presented the following descriptions of new Hymen-
opterst in the collection of the American J]ntomological Society :

Eucerceris bicolor. — 9- — Fulvo-ferruginous; strongly, closely and more
or less confluently punctured, the pubescence thin and pale except on apex of the
abdomen where it is black; apex of mandibles, tip of clypeal spine, spot enclos-
ing ocelli, most of thorax and the three apical segments of abdomen, black ; head
large, transversely quadrate; clypeus short and very broad, the apical margin
broadly arched, with a short acute tooth beneath median lobe, and another more
obtuse on either side just above the large tooth on mandibles, the median lobe
produced into a triangular subacute spine; labrum broad and subtruncate at tip;
mandibles with a large obtuse tooth within near base; thorax sometimes entirely
black, sometimes ferruginous with the sides only black, generally the prothorax.
seutellums and metathorax are more or less varied with ferruginous ; the triangular
enclosed space at base of metathorax transversely striated, the striations becoming

ENTOMOLOGICAL SECTION. XXXIX

oblique on the sides, the disk with a well impressed longitudinal line; meso-
pleura with a prominent angle beneath; wings yellowish subhyaline, the apex
with costal half fuliginous and subviolaceous, costal nerve and stigma fulvous;
abdomen with large deep uneven punctures, sometimes more or less confluent,
the transverse median depressions on the segments above more closely and finely
punctured; sometimes the depressed disk of apical segment is varied with fer-
ruginous. Length .60 — .65 inch.

Hah. — Montana, (Morrison). The clypeus is formed much as in
fulviceps Cress.

]flellinus abdoiiiiiialis.— 9.— Black; head and thorax almost smooth,
subopaque; short line on upper anterior orbits, flagellum beneath except at base,
palpi, narrow line on posterior margin of prothorax, transversely quadrate spot
on scutellum, a smaller one on postscutellum, upper margin of tubercles, some-
times a dot behind, spot on tegulse, apical half of four anterior femora beneath,
their tibise beneath and most of their tarsi, all lemon-yellow; apical middle of
clypeus produced, truncate, with a short acute medial tooth, the lateral angles of
the truncation more or less acute and dentiform ; the enclosed raised space at base
of metathorax above, smooth and shining, opaque and rugulose at base; wings
hyaline, iridescent, nervures black ; tips of posterior tarsi rufo-testaceous ; abdomen
shining, rufo-ferruginous, base of first, and the two or three apical segments more
or less black; first segment clavate, but not protuberant at tip above. Length
.40 — .45 inch.

% . — More slender than 9 , especially the abdomen ; anterior orbits, clypeus
more or less, most of mandibles, antennae beneath except the two apical joints,
the tenth and eleventh joints above, line on posterior margin of prothorax, spot
on tegulse, two beneath, another on scutellum and postscutellum, coxse beneath,
and sometimes a spot on eacih side of abdominal segments 3 — 5, white or yellowish-
white; all the femora and tibise beneath lemon-yellow; tarsi fulvo-testaceous,
except the posterior pair at base; the face, cheeks, thorax beneath and metathorax
with a silvery sericeous pile ; sides of clypeus generally stained with brown; first
segment of abdomen beneath and the three or four apical segments above and
beneath mostly black, apex beneath with a tuft of yellowish hair. Length
..3(1— .40 inch.

Hah. — Montana, (Morrison). Easily recognized by the ferruginous
abdomen, the first segment of which is not nodose at apex above as in
rujinodus, which it much resembles in form and sculpture.
