The following pages are principally confined to studies in our
Khynchophora, taken up some time since for the sole purpose of
distributing the nondescript material, forming a considerable part
of my cabinet, with a measurable degi'ee of scientific order and
succession. As usual in such cases, the compass of the work gradu.
ally outgrew the limited and personal objects had in view at the
beginning, and the investigations in several genera and groups
became sufficiently advanced to suggest the propriety of publishing
them, with the hope that they might i>rove useful to others similarly
engaged.
There is but little further to state in way of introduction. The
studies have been limited for the greater part to those groups which
appeared to stand most in need of revision, either by reason of the
large number of specific forms recently brought to light, especially
by skillful collecting in our western country, or because of apparent
misconception regarding generic identity, as in the case of the group
Desmorhines of LeConte. This section of the Erirhinini corre-
sponds with the Smicronychina of the European fauna, where it is
represented only by the genus Smicronyx, characterized by its con-
nate tarsal ungues and the basal constriction of the rostrum. In
our own fauna it is rather more abundant and diversified.
The Barini, or Baridiides, to which the greater part of the pre-
sent paper is devoted, constitute probably the largest tribe of
American Curculionidae, and, in South America, form the most
varied and characteristic element of the family, possibly excepting
the Zygopini. It is interesting to note in this connection, that the
recent researches of Mr. S. II. Scudder on the fossil beetle fauna of

several of our western Tertiary horizons seem to show that the
relative importance of the Barini in America dates from some-
what remote geological epochs.

CIIRCULIONID.E.
Erirhinini.
DORYTOMUS Stepli.
The separation of this genus from Erirhinus is largely a matter
of convenience, as the femoral teeth, constituting the principal dis-
tinguishing feature, are subject to great specific variations in devel-
opment, sometimes being barely distinguishable even on the anterior
femora, where they are generally most distinct. The genus presents
also considerable diversity of structure, and a very noticeable lack
of uniformity in the degree of sexual disparity, the three species of
the first group having extremely marked sexual differences pervad-
ing the entire anterior portion of the body. In the second group,
also consisting at present of three species, the sexual divergence is
still strong, although much less marked and affecting onlv the beak
and antennae, while in the third and by far the largest section the
sexual differences become very feeble.
In Dorytomus the body is oblong or oblong-oval, generally some-
what stout, more or less flattened above and frequently subinflated
behind, strongly punctured, especially in the elytral strife, and with
pubescence which is composed usually of short robust decumbent
hairs condensed in feebly defined spots, or, rarely, of scales similarly
uneven in distribution, generally without, but occasionally with,
erect bristling setffi in addition. The colors are usually rufo-testa-
ceous in different degrees of intensity, rarely becoming piceous or
black and more frequently paler ochreous or flavate. The tarsal
claws are slender, divaricate, very strongly arcuate, swollen inter-
nally near the base but never distinctly toothed. Other structural
characters will be referred to in the table given below.
The species are rather numerous, generally well characterized
structurally but variable in coloration. They belong especiall}^ to
the arctic fauna, extending southward in North America as far as
Goleopterological Notices, IV. 301
Arizona, and probably also throughout the elevated central region
of Mexico.
The following tabular statement may possibly facilitate the iden-
tification of the greater part of those species at present known to
collectors : —

arcuate at least in the female, the antennae inserted near the middle in

There are two other species, apparently belonging to this genus
and recently described b}^ Dietz (Trans. Am. Ent. Soc, XVIII,
pp. 262, 265)^ under the names Ah/codes dubius and EUeschus
angustatus. I have not studied the types of these species, but
dubius seems to be allied to the normal eastern forms such as
indifferens ; angustatus is almost certainly closel}- related to sqaa-
mosus, a small narrow species, with the femoral teeth very small,
the anterior alone distinct.
In regard to Erirhinus lutulentus and rutilus of Boheman, but
little can be stated positively. The description of the latter seems
to apply very well, however, to Anthonomus nubilus Lee, while
£. lutulentus may possibly be the same as Anchodemus angustus
Lee.
It is more than probable that the true affinities of EUeschus lie
strongly in the direction of Dorytomus, and that the toothed claws
form an exception of no more relative importance than the simple
claws of certain of the Anthonomini. It will in fact be found
• It should be stated in passing, that the genus Euclyptus of Dietz (1. c. p.
271) seems to be identical with Phyllotrox Sch. This genus is widely distri-
buted throughout North America and at least the northern part of South A merica,
also in the intervening islands. To tlie nine species mentioned in the Munich
Catalogue, should be added nubifer a.nd ferriK/ineus Lee, and tesUiceus Dietz;
there are several other species in my cabinet still undescribed. Phyllotrox is
one of the characteristically American genera of true Erirhinini, and is decidedly
out of place in the Anthonomini.

extremely difficult to maintain the Erirhinini, Anthonomini and
Tychiini as satisfactory triljes, their limits being not at all well
defined under the present scope. It would be more in accordance
with natural affinities to unite them, and the resultant tribe might
then be readily subdivided into numerous well-marked groups or
subtribes.
1 I>. inaequalis n. sp. — Oblong, slightly sabcuneate, feebly convex ;
integuments black, obsoletely mottled with testaceous, especially laterally ;
vestiture rather dense but not altogether concealing the shining surface,
somewhat line, moderately long, subrecumbent, finely and confusedly mottled
paler and darker, with numerous long erect and bristling setae. Head with a
large deep frontal fovea, the eyes large, feebly convex ; beak long, equally,
evenly and rather strongly arcuate throughout in both sexes, two-thirds longer
than the prothorax, deeply punctate and longitudinally sulcate, with the
antennae inserted rather beyond apical two-fifths in the male, slightly more
slender, very much longer, fully two-thirds as long as the body, cylindrical,
finely but closely seriato-punctate, with the antenna; inserted at the middle in
the female. Prothorax in the male large, transversely oval, fully as wide as
the base of the elytra and more than one-third as long as the latter, in the
female much smaller and more transverse, distinctly narrower than the base
of the elytra and scarcely more than one-fourth as long as the latter ; punc-
tures rather coarse, deep, moderately dense. Elytra with the sides straight
in basal two-thirds, nearly parallel in the male but feebly divergent from the
humeri in the female, obtusely parabolic in apical third ; striae slightly im-
pressed, the punctures coarse, very deep and approximate ; intervals nearly
flat, finely, not densely punctate. Abdomen finely and densely punctate.
Length 5.4-6.5 mm. ; width 2.3-2.8 mm.
California (Los Angeles).
The sexual differences in this species are more pronounced by far
than in any other within our fauna. In the male the basal joint of
the antenna! funicle is but slightly longer than the next two, the
anterior legs slender and very long, the femur and tibia each one-
half as long as the entire body, the latter evenly, feebly arcuate and
slightly spijiulose along the inner margin, and the corresponding
tarsi have the basal joint longer than the remainder and but slightly
shorter than the prothorax, with the inner edge finely and unevenly
serrulato-granulose. In the female the second joint of the funicle is
slightly longer but not as long as the next three, and the anterior
legs are normal, the tarsi stout, with the basal joint shorter than
the remainder. This species has been confounded wnth miicidutt
heretofore, but differs greatly as may be judged by the description.

the prothorax, feebly arcuate, coarsely, deeply, rugosely punctate and longi-
tudinally sulcate, with the antennae inserted slightly beyond the middle, the
basal joint of the antennal funicle as long as the next three ; in the female
the beak is a little more slender, evenly and strongly arcuate, much more
than twice as long as the prothorax, smooth, more finely, sparsely punctate,
with the antennae inserted a little behind the middle, the basal joint of the
funicle as long as the next four. Prothorax not coarsely, deeply, somewhat
sparsely punctate, with an impunctate median line ; in the male it is trans-
versely oval, slightly narrower than the elytra and about one-third wider
than long, in the female smaller, more transverse, more broadly truncate at
apex, much narrower than the elytra and about one-half wider than long.
Elytra three-fourths longer than wide, the sides straight and parallel in the
male or feebly divergent from the base to apical third in the female, the apex
obtusely rounded, the sutural notch rather large and distinct ; strial punc-
ture rather large, deep, closely approximate ; intervals finely, somewhat dis-
tinctly and closely punctate. Ahdomen rather strongly, not densely, unevenly
punctate. Length 5.7-7.0 mm. ; width 2.3-2.9 mm.
Arizona.
This species is closely related to mucidus, but may be distin-
guished by the slig-htly longer beak with the antennae a trifle less
apical in insertion in both sexes, by the abundant, erect but short
setge, bristling throughout the dorsal surface, and by the relatively
more elongate anterior legs of the male, the basal joint of the tarsus
in that sex being about equal in length to the remainder; it is dis-
tinctly shorter in mucidus.

the antennae inserted at the middle ; antennae slender, with the basal
joint of the funicle about as long- as the next four together, the
second as long as the next two, differing but slightly in the sexes.

fourths longer than wide, the strial punctures coarse, deep, moder-
ately close-set, the intervals feebly convex, minutely, feebly, rather
sparsely punctulate. Length 5.0-6.5 mm.; width 2.0-3.0 mm.
Canada, Indiana and Nebraska. The sexual differences are
slightly less pronounced than in breviselosvs and very much less
so than in ineequalis, and this species is readily distinguishable
from both by the absence of erect setae. In the male the anterior
legs are elongated, but the basal joint of the tarsus is shorter than
tiie remainder and about one-half as long as the prothorax.
4 D. laticollis Lee— Proc. Am. Phil. Soc, XV, p. 164.
Piceous-black, variegated with small distant spots of rufo-piceous,

rather closely punctate. Abdomen finely, not very densely punc-
tate. Length 4.4 mm.; width 1.9 mm.

occurs at Lake Superior and in Iowa according to LeConte.
f) D. aniplUS n. sp. — Oblong, feebly convex, robust, strongly shining,
pale brownish-Havate thronghout ; vestiture very sparse, consisting of small

Colorado.
A rather large species allied to laticollis and parvicollis, but
differing in its entirely pale reddish-ochreous coloration, and much
broader form. The two specimens before me are apparently males.

fovea; beak in the male somewhat stout, feebly but distinctly arcuate, coarsely
deeply and closely punctate in longitudinal furrows, strongly and conspicu-
ously setulose and slightly longer than the head and prothorax, distinctly
less than one-half as long as the elytra, with the antennae inserted just

very deep, perforate, close-set ; intervals nearly flat, minutely, feebly, rather
sparsely punctate. Abdomen finely, evenly, not densely punctate. Length
4.5-5.5 mm. ; width 2.U-2.2 mm.
Indiana.
Allied to laticoUis, but disting-uishable by the pale coloration and
especially by the shorter, more robust beak of the male and the
slightly larger eyes of the same sex ; the beak and head are also
much more coarsely and densely punctate and setose. The tooth
of the anterior femur is larger in the jiresent species than in lati-
collis, and the elytra are parallel in the male and not gradually
feebly inflated behind.
7 D. liystricilla n. sp. — Oblong-oval, convex, feebly shining, piceous-
black and more or less rufescent toward the sides, to pale rufo-testaceous
throughout ; legs always pale ; vestiture dense, consisting of short stout
pointed and decumbent hairs, cinereous in color and but feebly mottled, the
pronotum Avith two narrow indefinitely nubilate darker vitt;©, the elytra
bristling also with long erect stiff setse, not close-set in a single line on each
interval. Head and beak very densely punctate throughout, the latter not
longitudinally carinulate or sulcate, in the male short, about as long as the
prothorax, with the antennse inserted at apical third, in the female just visi-
bly longer, but not longer than the prothorax, with the antennje inserted at

California (San Francisco to Los Angeles).
One of the most abundant of the Californian species and repre-
sented before me by a large series. It varies greatly in color, and
closely resembles mannerheimi Gemm. ; the latter, however, com-
pletely lacks the long coarse erect seta; which are so conspicuous in
hystricida.
8 D, liispidllS Lee— Proc. Am. Phil. Soc, XV, p. 167.
Oblong, somewhat stout, convex, feebly shining, pale flavo-
testaceous throughout except the sterna of the hind body, which,
as in hirtus, are blackish; vestiture dense, consisting of robust
recumbent hairs, feebly subdenuded in uneven wavy blotches on
the elytra behind the middle, and with coarse erect bristles of
moderate length. Head very densely punctate and coarsely pubes-
cent, the beak in the female subglabroiis toward apex, very feebly,
evenly arcuate, rather slender, not quite as long as the head and
prothorax, the antenn® inserted at at)ical two-fifths; between the
bases of the antenna? there is a dilated flat polished and impunctate
area. Prothorax small, more than one-half wnder than long, parallel
and rounded on the sides, convergent and sinuate, but not strongly
constricted, near the apex, the latter three-fourths as wide as the
base; punctures moderate in size, deep, dense, the impunctate line
narrow and distinct. Elytra at base fully one-third wider than the
prothorax, much more than three times as long, parallel, gradually,
evenly parabolic in more than apical third; strial punctures moder-
ately large, very deep and close-set ; intervals about three times as
wide as the punctures. Abdomen densely, rugosely punctate. Legs
short. Length 3.6 mm.; width 1,4 mm.
New Mexico. Cab. LeConte. A distinct species not closely
allied to any other ; it differs from hirtus in its smaller, narrower
prothorax, and the shorter and sparser pubescence of the elytra,
although the erect setse are similar to those of that species in length
and abundance; also, as remarked by Dr. LeConte, in the absence
of the interantennal sulcus.
9 D. liirtus Lee— Proc. Am. PliiL Soc, XV, p. 166.
Oblong, robust, convex, somewhat shining, pale flavo-testaceous,
the beak piceous ; sterna and their parapleurje black ; vestiture
dense, consisting of long robust recumbent hairs, yellowish-white
in color, scarcely mottled but suljdenuded in a large clouded spot

near the middle of each elytron ; el3'tra and beak toward apex
bristling with stiff suberect setae. Beak in the female not very-
stout, evenly, feebly arcuate, as long as the head and prothorax,
rather sparsely puactate and siibglabrous except above in basal
half, with an elongate indentation between the antennae, the latter
inserted just behind apical third, the basal joint of the funicle not
quite as long as the next three ; club moderate, not darker in color.
Prothorax two-thirds wider than long, parallel and rounded at the
sides, convergent and just visibly constricted anteriorly, the apex
nearly three-fourths as wide as the base ; disk rather finely, some-
what closely punctate, without distinct impunctate line. Elytra at
base barely one-fourth wider than the prothorax, three and one-half
times longer than the latter, subparallel, ogival in apical third, the
striae feebly impressed, the punctures rather small, not very close-
set ; erect setae forming a single line on each interval. Length .3.7
ram.; width 1.65 mm.
California (San Diego). Cab. LeCoute. Represented by the
unique female type. Hirtits is allied to hi/stricula, but is immedi-
ately distinguishable by its larger and more transverse prothorax,
stouter bodily form, longer beak, very much finer strial punctua-
tion and many other characters. The erect setae of the elytra are
decidedly shorter and more numerous than in hydricula.
10 D. filiolus n. sp. — Obloug-oval, rather stout, convex, sliinius', pale
flavate throughout; vestiture rather sparse, consisting of long, somewhat fine,
recumbent and ashy pubescence, not perceptibly variegated, the elytra brist-

The single specimen serving as the type is probably a female.
This species is one of the smallest of the genus and is somewhat
allied to hijslricula, but differs greatly in its coarser, sparser punc-
tuation, sparser pubescence and especially in the form of the pro-
thorax, which is shorter, more strongly narrowed anteriorly and
not at all constricted behind the apical margin.

Oblong, moderately stout, convex, scarcely shining, densely and
almost uniformly clothed tliroughout with short robust recumbent
hairs of a dark cinereous tint, and without long erect set« ; body
black, the legs piceous ; antennte paler, piceous. Beak very short,
stout, densely punctured and setose but not longitudinally grooved,
opaque, feebly arcuate and ecpiai in length to the prothorax ; antennoe
inserted but slightly beyond apical two-fifths, the basal joint of the
funiele robust and but little longer than the next two. Prothorax
short, fully one-half wider than long, parallel and rounded on the
sides, strongly constricted and broadly subtubulate at apex, ex-
tremely densely, not very coarsely punctured, without impunctate
line. Elytra at base much wider than the prothorax and about
three and one-half times as long, the sides parallel and straight,
rounded in apical third, with a small sutural notch : striae rather
coarsely deeply and closely punctate, not strongly impressed ; inter-
vals but slightly wider than the strial punctures, densely punctu-
late. Length 2.1 mm.; width 1.25 mm.
Alaska. Cab. LeConte. Easily distinguishable from the other
Alaskan species by its dense and uniform pubescence and shorter,
broader, more parallel form. It is doubtful if the name substituted
by Gemminger should be retained, as the south African vesiitus is
possil)ly a true Erirhinns. Tiie anterior femora in mannerheimi
are distinctly toothed; the others are not in a favorable position for
observation in the single specimen \\hich I have studied. The pro-
notal vittfe, mentioned by Mannerheim, are obliterated in this ex-
ample, and the small subdenuded spots of the elytra are extremely
feebly defined.

Alaska. Cab. LeConte. The single specimen, from which the
above outline is drawn, is a female, the abdomen being evenly con-
vex toward base. It is quite closely allied to luridus but is a
larger, stouter species, with shorter and thicker beak, always pale
in color and with decidedly smaller eyes, so that when the insect is
viewed in profile, there is a large part of the head visible above them.

A small, somewhat narrow and convex species allied to luridus,
but di.stin^uishable by its black coloration and by the much greater
sexual disparity in the length of the beak, the latter being actually

but differs in its narrower form, more strongly convergent sides of
the prothorax toward apex, the latter being very much narrower
when compared with the base, in its decidedly coarser punctuation,
especially of the pronotum, and in the coarser, denser vestiture.
The two specimens before me are apparently males, and the one
from Minnesota is pale flavo-testaceous throughout, probably from
immaturity, with the frontal fovea practically obsolete, this not

sides, becoming more convergent, nearly straight and not visibly constricted
anteriorly ; apex broadly arcuate, nearly three-fourths as wide as the base ;
disk rather coarsely, very deeply and extremely densely punctate, without
trace of imi^unctate line. Elytra at base nearly one-half wider than the pro-
thorax, more than three times as long as the latter, acutely parabolic in apical
two-fifths, the sutural notch very small and feeble, strial punctures moderately
coarse, very deep, close-set ; intervals minutely, indistinctly punctate. Abdo-
men not coarsely but deeply, very densely punctate. Legs short ; femora stout,
picescent toward apex, the tooth small but distinct on all, the intermediate and
posterior with a large polished glabrous area on the posterior side in basal half.

This is an isolated species, comparable only with squamosus, but
dififering greatly in its rather more robust form, stout beak, black
color and strongly marked maculation of linear white scales.

SmiCROIVYX Schonh.
Pachytychius Lee. iiec Jekel ; Desmoris Lee.
The genus Pachytychius of Jekel, as represented by the European
squamosvs Gyll., examples of which have been recently sent me
by M. Desbrochers des Loges, has the beak unconstricted at base
and similar to that of Tychius, and the tarsal claws small, simple,
divergent and distant at base, forming in fact one of the connective
bonds between the Erirhinini and Tychiini. Pachytychius does not
appear to be represented in the American fauna, and the two species
provisionally placed there by LeConte are entirely identical in all
structural characters, which can in any way be considered of generic
worth, with the form described by that author as Smicronyx corpu-
lentus and the other species placed in Smicronyx.
Desmoris of LeConte was founded upon two species of rather
larger size than the others, but, if care be taken to examine D. con-
strictus, it will be found a perfect homologue of such species as
Smicronyx sordidus and griseus, in all points of facics and structure.
Smicronyx is a rather large genus, constituting a special group
of the Erirhinini, characterized by the strong basal constriction of
the beak and the simple tarsal claws which are invariably connate
in basal third or fourth. It is somewhat heterogeneous in the ex-
ternal aspect of its species, both here and in Europe, but as far as
can be perceived is entirely uniform in the essential generic struc-
tures referred to, as well as in abdominal structure, in the coarsely
faceted eyes, somewhat approximate beneath, and in the deeply sin-
uate apical margin of the prosternum. The elytra are, as a rule,
distinctly wider at base than the disk of the prothorax, but are not
as elongate as in Dorytomus, and are generally acutely rounded
behind in apical half, Avith the tenth stria very short and remote
from the ninth, closely approaching the latter behind the humeri.
The scutellum is small, the legs rather short and stout, the femora
unarmed, the tibial spur distinct, and the third tarsal joint dilated
and bilobed, the fourth being somewhat short or moderate in length.
The species are small in size, and include among them some of
the most minute curculionides known to us at present. Those of
our fauna may be provisionally classified as follows : —
Fifth elytral interval densely clothed nearly throughout with white scales ;

A distinctly marked species, apparently rather abundant. My
first specimens were received some years since from Mr. F. M.

corpulei^tus and discoideus, where they radiate from a central point.
The punctures toward the middle of the pronotum are also different,
being- transverse and not rounded.

Texas (Austin and El Paso); Arkansas and Louisiana. I found
this species some years ago in great abundance on the banks of the
Colorado River, in June. It is allied to discoideus and differs in
its fine elytral stria? toward the middle and base, in the narrower
bodily form and smaller size, red legs, and in the color of the vesti-
ture. The brown subbasal spot of the elytra is frequently obsoles-
cent.

The moderately large size, robust convex form, large scales and
generally rough hispid appearance will aid in the identification of

less punctate and squamose, the antennae being inserted just beyond

and prothorax and just visibly more than one-half as long as the elytra, with
the antennae inserted at apical two-fifths ; basal fasciculate tufts rather dis-
tinct ; antennae short, the second funicular joint but slightly longer than the
third. Prothorax very nearly as long as wide, the sides broadly, evenly arcuate,

The live specimens in my cabinet display scarcely any variation.
This is one of the most minute species of the genus, and will be
easily known by the characters given.

bolic ; striaj indicated only by narrow and rather ill-defined partings of the
vestiture. Length 1.9 mm. ; width 0.85 mm.
Texas.
The single female l)efore me represents a species somewhat allied
to silaceus, but decidedly different in its shorter, broader form,
wider elytra, longer beak in the female and uniformly, densely
covered pronotum.

Kansas, Colorado and Montana. The tarsal claws in this distinct
and easily recognizable species are unusually long and divergent
but connate at base.
15 S. sparsiis n. sp. — Oblong-oval, convex, deep black throughout, the
vestiture of the upper surface consisting of small elongate-oval whitish scales,
uniform throughout and very sparsely scattered over the elytra, the strire in-
dicated by partings which are wider than the grooves, rather denser, and
wider beneath on the sterna and their side-pieces. Head subglabrous, aluta-
ceous, finely but strongly reticulate ; transverse constriction well marked, fine ;
beak in the male rather long, evenly cylindrical and somewhat thick through-
out, feebly, evenly arcuate, sparsely but strongly punctate and subglabrous

pointed, distinctly divergent but completely connate at base. Length 2.5
mm. ; width 1.1 mm.
Colorado.
The single specimen represents a species allied to sordidua and
griseus, but differs in the small, widely-scattered scales and black
legs. From the male of so?rlidus it differs in its much longer, non-
tapering, sparsely squamulose beak, with the antennae inserted at
the middle. The male of griseus I have not at hand, but the female
differs from the type of sparsus in its very much larger and more
elongate prothoi-ax.

16 S. pleiiralis n. sp. — Robust, oblong-oval, convex, black, the legs red
with the tarsi darker, extremely densely clothed above with large scales, ab-
ruptly white in lateral sixth of the pronotum and more than lateral fourth of
the elytra, elsewhere above dark red-brown, smaller, whitish, very dense

rowly parabolic, with the convergent sides nearly straight ; strise fine, deep
toward the middle when denuded. Length 2.0 mm. ; width 1.0 mm.
Arizona.
A single specimen which is probably a female ; the second ventral
segment is minutely but quite distinctly angulated posteriorly at the
sides.
17 S. olbtectus Lee— Proc. Am. Phil. Soc, XV, p. 171.
Oblong-oval, convex, deep black throughout, polished when de-
nuded, the pronotum then strongly, closely, evenly punctured ;
integuments densely clothed with rather large, deeply and coarsely
strigose, elongate-oval scales, widely overlapping longitudinally on
the elytra, dark brown in color, very feebly and indefinitely mottled
with cinereous toward the sides ; recurved setae as usual. Beak in
the male rather thick, feebly arcuate, densely squamose, opaque,

as the head and prothorax, otherwise similar to that of the male,
the antennte inserted just visibly beyond the middle; basal squamu-
lose tufts very prominent ; antennae moderate, the basal joint of
the funicle subequal to the next three, second one-half longer than
the third. Prothorax large and long, fully as long as wide, the
sides parallel and broadly arcuate, becoming convergent and strongly
constricted toward apex, the latter three-fourths as wide as the base.

basal half, then narrowly parabolic ; striae fine, deep, strongly punc-
tured laterally. Length 1.8-2.8 mm.; width 0.75-1.2 mm.
California (Los Angeles and San Diego). A very distinct spe-
cies, easily identifiable by its large elongate prothorax. The vesti-
ture is very easily abraded, and, out of a large series which I took
at San Diego, there is scarcely a specimen having more than a few
scattered scales on the upper surface. One specimen in my cabinet
is labeled "Arizona."
18 S. sordidus Lee— Proc. Am. Phil. Soc, XV, p. 173.
Oblong-oval, convex, black, the legs dull rufous; integuments
densely clothed with moderately large, broadly oval scales, uniform
in coloration, ochreous to cinereous on the upper surface, whiter
beneath ; recurved setse small and distant. Beak in the male short,
thick, nearly straight, feebly tapering from base to apex, coarsely,
densely squamose except near the apex, coarsely punctate, scarcely
longer than the head and prothorax, with the antennae inserted a
little beyond the middle, in the female long, very slender, equally,
evenly cylindrical and feebly arcuate throughout, smooth, finely,
sparsely punctate, squamose only very near the base, one-half longer
than the head and prothorax and scarcely visibly shorter than the
elytra, with the antennae inserted somewhat behind basal two-fifths ;
antennae slender, the second funicular joint slightly shorter than
the next two. Prothorax distinctly narrowed from base to apex,
broadly, rather strongly rounded at the sides, deeply constricted
behind the apex, the latter three-fourths as wide as the base ; disk
convex, slightly wider than long. Elytra at base one-fourth to
one-third wider than the prothorax, two and one-half times as long.
Length 2.1-2.4 mm.; width 0.8-1.05 mm.
Texas. A rather small species, allied completely in the structure
of the beak, both in the male and female, to constrictus (Desmoris).
The original description is greatly in error in stating that the tarsal
claws are not connate ; they are rather long and completely connate
in basal fourth. The head behind the transverse groove is abruptly
and completely glabrous, highly polished, sometimes with merely a
very feeble transversely wavy strigilation, while in griseus it is dull
and strongly, coarsely reticulate.

Oblong'-ov^al, black, densely and uniformly clothed with elongate-
oval appressed scales, cinereous to ochreous in color, each interval of
the elytra with a single series of short robust recurved squamules.
This species is either one of the most variable of curculionides in
structural peculiarities affecting parts of the body referred to by
LeConte for generic characters, or the large series before me is
made up of closely allied species which can only be differentiated by
the collection of abundant material from carefully recorded localities.
I will at present simply describe certain modifications noticed in three
female types taken in Iowa, New Mexico and northern California
respectively :
1 — Beak fully one-half as long- as the body, extremely slender;
basal joint of the funicle barely as long as the next two, the second
fully three-fourths as long as the first; legs, tarsi and antennae pale
rufous; beak rufescent.
2 — Beak very long, nearly two-thirds as long as the body, thicker ;
basal joint of the funicle fully as long as the next three ; second one-
half as long as the first; legs, antennae and beak throughout l)lack.
3 — Beak much shorter, stouter, two-fifths as long as the body ;
basal joint of funicle longer than the next two; legs rufous, the
tarsi darker; beak and antenna blackish, the club paler.
In the male the beak is very much shorter and thicker, densely
punctate, squaraose, with the antennae inserted just beyond the
middle. Length 2.2-4.0 mm. ; width 1.0-1.8 mm.
Iowa to Arizona, northern California. A very abundant species;
the smallest and largest in my series of thirty or more specimens
are both females.
20 S. griseilS Lee. — Proc. Am. Phil. Soc, XV, p. 171.
Narrowly oblong-oval, convex, black, the legs dark riifo-piceous ;
scales moderate in size, broadly oval, dark brownish and paler, dense
but not overlapping on the upper surface, white and very dense
beneath. Beak in the female very slender, cylindrical, just visibly
bent, much longer than the head and prothorax and nearly tw^o-
thirds as long as the elytra, punctured, opaque and squamulose
toward base, smooth and with small subelongate erosions toward
apex ; antennae inserted slightly behind the middle, short, the scape
not quite attaining the eye ; second funicular joint but slightly
longer than the third. Prothorax large, fully as long as wide, sub-
parallel and broadly, evenly and strongly arcuate at the sides, rather

toward the apex, the latter three-fourths as wide as the base ; disk
convex, rather coarsely, deeply, densely punctate, widest behind the
middle. Elytra at base scarcely more than one-fourth wider than
the prothorax, just visibly more than twice as long, one-half longer
than wide, parallel in basal half, then regularly, acutely ogival, not
constricted before the apex ; striae deep but not very coarse. Tarsal
claws rather small, nearly parallel, connate toward base. Length
2.3 mm.; width 0.9 mm.
Texas. Resembles scapalis, except in the color and disposition
of the scales and in its very much smaller size.
21 S. COlinivens n. sp. — Oblong-oval, moderately stout ami convex,
piceous-black, the beak, antennae and legs throughout rufous ; vestiture very
dense and uniform, consisting of moderately large, coarsely strigose, grayish-
white scales, with intermixed recurved setae, concolorous, dense and but
slightly smaller on the under surface. Head not very densely squamulose,
the constriction feeble ; beak in the female very slender, gradually, just visi-
bly thicker from the antennse to the base, feebly, evenly arcuate, polished and
impunctate in apical half, thence gradually more punctured, opaque and
sparsely, finely squamulose to the base, much longer than the head and pro-
thorax and about three-fifths as long as the elytra, the basal tufts composed
of long slender squamules ; antennae inserted at the middle, the second funi-
cular joint three-fourths as long as the first and about equal to the next two.
Prothorax very nearly as long as wide, the sides broadly arcuate, gradually
convergent, broadly and just visibly sinuate to the apex, the latter scarcely
more than two-thirds as wide as the base ; disk strongly, densely punctate
and subrugose, the punctures tending strongly to coalesce. Elytra at base
two-fifths wider than the prothorax, not quite three times as long, slightly
less than one-half longer than wide, the sides straight and parallel in basal
three-fifths, the apex evenly ogival ; striae indicated by coarse partings of the
vestiture. Legs rather loaig and decidedly slender ; tarsal claws as usual.
Length 2.3 mm. ; width 1.0 mm.
Missouri (St. Louis). Mr. Hugo Soltau.
A moderately small species, without any striking features, but
evidently different from any other here brought to notice. It ap-
pears to combine certain of the characteristics of sordiclus and Jiavi-
cans, but differs from the former in its much shorter beak and medial
antennte in the female, and from the latter in the disposition of the
vestiture. It is represented by a single female specimen.
22 S. sei-iatus Lee— Proc. Am. Phil. Soc, XV, p. 172.

above, especially at the base of the third interval, uneven in distri-
bution near the suture, very dense and white throughout beneath ;
upper surface with the usual stout recurved sette not especially
prominent. Beak in the female rather long, punctate, decidedly
squamulose except beyond the antennas, very feebly, evenly arcuate
and about three-fifths as long as the elytra ; antennae inserted at the
middle, rather short, the second funicular joint but very slightly
longer than the third. Prothorax small, as long as wide, the sides
rounded, feebly convergent and quite distinctly constricted ante-
riorly, densely and confusedly squamose and setose. Elytra at base
nearly one-half wider than the prothorax, about three times as long,
one-half longer than wide ; sides parallel and straight to the middle,
then gradually narrowly parabolic ; striae fine, with large elongate
punctures toward the sides ; vestiture generally more denuded
toward the middle. Length 1.15-2.5 mm.; width O.T-1.0 mm.
California (Mariposa) — Cab. LeConte ; Arizona and Texas. A
small species, distinguishable by its small elongate prothorax and
rather long beak, which is punctured and more or less squamulose
almost throughout, even in the female. In the male it is short, very
densely squamose and hispid, as long as the head and prothorax and
with the antennae inserted near apical third. It was taken in great
abundance by Mr. Dunn at Benson, Arizona.
The Texan form identified by LeConte as cornicidatus, belongs
to this species.
23 S. fidlicialis n. sp. — Oblong-oval, convex, rather shining when de-
nuded, black, the legs rufous, blackish at base ; elytra broadly pale and rufes-
cent toward the sides ; vestiture of the pronotum dense and squamiform at the
sides, becoming sparser and fine toward the middle, that of the elytra dense
and nearly uniform, consisting of elongate-oval, pointed, yellowish scales,
more condensed and coarser in wavy subtransverse areas ; on the under sur-
face yellowish-white, the scales smaller and more rounded, dense. Head finely
squamulose, the constriction deep, the two corniculate tufts long and conspicu-
ous ; beak in the male moderately tliick, even throughout, not tapering, dull,
punctate, deeply furrowed and feebly arcuate toward apex, a little longer
than the head and prothorax, nearly one-half as long as the elytra ; antennae
inserted at apical third, the second funicular joint but slightly longer than
the third. Prothorax very nearly as long as wide, the sides broadly, evenly,
not very strongly arcuate, moderately convergent, broadly and feebly sinuate
toward apex ; disk convex, rather coarsely, deeply, evenly and densely punc-
tate, the punctures rounded and all distinct. Elytra at base scarcely two-
fifths wider than the prothorax, two and one-half times as long, more than
one-half longer than wide, evenly elongate-ogival throughout, the sides not

becoming quite parallel toward base ; strife fine, deep and abrupt toward the
suture. Length 2.5 mm. ; width 1.1 mm.
Iowa.
The only species with Avhich this can be compared are Jiavicans
and scapalis, but it differs greatly from the former in its longer
prothorax, Avith even circular and distinct punctures and slender
sparse squamules toAvard the middle ; in Jiavicans the pronotum is
coarsely, densely squamose throughout, and the sculpture consists
of more or less pronounced oblique furrows, caused by the coales-
cence of the punctures. Scapalis is a much larger, stouter species,
with different color and structure of the vestiture.
24 S. scapalis Lee. — Proc. Am. Phil. Soc, XV, p. 168 (Desmoris).
Oval, convex, black; legs dull-rufous, blackish toward base; ves-
titure consisting of ochreous-yellow scales, moderately dense and
forming subtransversely wavy condensed areas on the elytra. In
the male the beak is densely punctured, moderately slender, rather
longer than the head and prothorax, the antennae inserted slightly
beyond the middle, the basal joint of the funicle equal to the next
two ; in the female it is slightly longer but scarcely more slender,
smoother, almost straight, the antennae inserted scarcely at all be-
hind the middle, the basal joint of the funicle distinctly longer than
the next two, the club longer and narrower. Prothorax very nearly
as long as wide, widest behind the middle ; sides broadly arcuate,
convergent and sinuate toward apex ; disk rather coarsely, deeply,
densely punctate. Elytra at base about one-third wider than the
prothorax, scarcely more than twice as long, the sides straight and
parallel in basal third, then gradually ogival; striae narrow, deep,
abrupt, obscurely punctate at the bottom. Length 3. '7-4. 2 mm.;
width 1.1-2.0 mm.
Illinois. One of the largest species of the genus, greatly resem-
bling Jiavicans in the color and disposition of the elytral vestiture,
but very different in its more elongate prothorax. It differs radi-
cally from constrictus, with which it has been associated, in the
loes pronounced sexual differences in the beak, and in the peculiar
arrangement of the elytral scales.

mottled on the elytra and generally with a short whitish line at the
base of the third interval. Beak in the male one-half as long- as the
elytra, very feebly arcuate, punctured and squamose, the antenntt
inserted a little beyond the middle, the second joint of the funicle
slightly longer than the third ; in the female but very slightly longer,
more slender, smooth, squamulose toward base, very feebly arcuate,
the antennae inserted slightly behind the middle, the second funicular
joint as long as the next two. Prothorax slightly wider than long,
the sides convergent but not noticeably constricted toward apex, the
latter two-thirds as wide as the base. Elytra at base two-fifths
wider than the prothorax, between two and three times as long,
one-half longer than wide, the sides nearly straight and parallel in
basal half; striae fine. Length 2.3-3.0 mm.; width 1.0-1.5 mm.
Texas, Dakota and Indiana. A rather common species, above
the average in point of size, and easily recognizable by the peculiar
condensations of larger and paler scales on the elytra, the vestiture
of which is, however, very dense throughout. In one male speci-
men the beak is not longer than the head and prothorax, and very
much less than one-half as long as the elytra.
26 S. COngestllS n. sp. — Oval, convex, pale rufo-testaceous througliout,
the elytral suture narrowly picescent ; vestiture sparse and uneven, yellowish-
white, consisting of fine slender sparse squamules, which become larger and
pquamiform in the condensed spots, of which there are several on the prono-
tum ; elytra with large subtransverse wavy condensed areas ; metasternum
and abdomen sparsely clothed with very fine elongate squamules, the met-
episterna densely squamose. Head with a few fine squamules anteriorly ;
constriction evident ; beak in the male moderately thick, not tapering, feebly
bent toward apex, opaque, sparsely squamulose, the basal tufts not well
developed, longer than the head and prothorax and more than one-half as
long as the elytra ; antennse inserted rather beyond apical third, slender, the
second funicular joint scarcely longer than the third, both elongate and one-
half longer than the fourth. Prothorax but slightly wider than long, sub-
parallel and strongly, evenly arcuate at the sides, feebly narrowed and finely
distinctly constricted near the apex ; disk convex, rather coarsely, deeply and
closely punctate, the punctures circular. Elytra at base one-third wider than
the disk of the pronotum, two and one-half times as long, two-fifths longer
than wide, ogival, the sides gradually becoming almost parallel and feebly
arcuate toward base; strise distinct. Length 2.0-2.2 mm. ; width 1.0-1.1.5 mm.
Colorado; District of Columbia.
There is no species with which this can be regarded as closely
allied. It somewhat suggests tychioides, but the pronotal sculpture
is of an entirely different order, and it differs from any other form
402 Coleopterological Notices, IV.
known to me in the elongate third joint of the antennae. The speci-
men from the District of Columbia exactly resembles the Colorado
type, but has the beak still longer, two-thirds as long as the elytra,
smoother, more evenly arcuate, with the antenna3 inserted at apical
two-fifths; it is without doubt the female.
27 S. tycliioides Lee— Proc. Am. Phil. Soc, XV, p. 171.
Oval, convex, shining, black, the elytra with a very feeble sub-
lateral rufescent vitta ; legs red, black near the coxae ; tarsi blackish ;
vestiture of the upper surface sparse and uneven, very fine and
sparse on the pronotum, yellowish and condensed in uneven sub-
transverse spots of coarse scales on the elytra, the interspaces thinly
sprinkled with fine short squamules ; under surface very densely
clothed throughout with small rounded yellowish-white scales.
Beak thick and gibbous toward base, strongly tapering, thin and
smooth toward apex, evenly, rather feebly arcuate, slightly longer
than the head and prothorax ; antenna3 inserted slightly beyond the
middle, the second funicular joint nearly as long as the next two.
Prothorax rather large, strongly convex, slightly wider than long,
strongly rounded at the sides, the latter moderately convergent,
broadly and just visibly sinuate near the apex; punctures reniform
or lunate, small, rather sparse, becoming larger and rugose laterally,
without trace of median line; interspaces polished, not reticulate.
Elytra at base one-fourth wider than the prothorax, a little more
than twice as long, one-third longer than wide, elongate-ogival,
becoming almost parallel near the base. Length 2.2 mm. ; width
1.1 mm.
Kansas. I am not certain of the sex of the single example before
me, but the thick, strongly tapering beak would appear to indicate
the male.
28 S. sagittatUS n. sp. — Oblong-oval, convex, feebly shining, black, the
antennae piceous witli the club paler ; legs and tarsi pale rufous, coxae darker ;
elytra black, with a broad pale rufous and oblique vitta on each from the
humeri to the apex ; vestiture almost entirely denuded in the type, but appa-
rently sparse and uneven as in tychioides. Head dull, the constriction moder-
ately strong ; beak thick, dull, equal in diameter and extremely feebly evenly
arcuate throughout, a little longer than the head and prothorax ; antennae
inserted at apical third, the second funicular joint but slightly longer than
the third. Prothorax moderate in size, convex, quite distinctly wider than
long, the sides evenly, rather strongly rounded, convergent but scarcely con-
stricted anteriorly ; disk dull, the sculpture fine, not very deep, extremely

dense and peculiar, consisting of long oblique uneven eroded channels, which
are evidently formed by the coalescence of reniform punctures of the tijrhioides
type, but also with an even median line, entirely impunctate and finely
granulato-reticulate. Elytra at base one-third wider than the prothorax, fully
two and one-half times as long, one-half longer than wide, ogival in apical
half, the sides thence straight and parallel to the base ; humeri right, promi-
nent but narrowly rounded ; strise deep, punctate toward the sides. Length
2.0 mm. ; width 0.85 mm.
Rhode Island.
This species, while allied to tycMoides and sculpticoUis, is dis-
tinct from both in the narrow granulose clearly limited impunctate
median line of the pronotiim ; the latter is larger than in sculpti-
coUis, but smaller than in tijchioides. It is represented by a single
male example.
29 S. SCIlIpticollis n. sp. — Narrowly oval, convex, feebly shining,
black, the antennfe piceous, the legs red, darker near the coxae, the tarsi
piceous ; elytra bright rufous, the suture broadly, suffusedly blackish ; vesti-
ture sparse and uneven, fine and sparse at the sides of the prothorax, con-
fusedly mottled with condensed areas of larger yellowish-white scales and

just behind apical third, in the female slightly longer and smoother, evenly
cylindrical, evenly, moderately arcuate, nearly three-fifths as long as the
elytra, with the antennae inserted at apical two-fifths ; antennae moderate, the
second funicular joint much shorter than the next two. Prothorax small,
slightly wider than long, convex, strongly, evenly rounded at the sides, feebly
narrowed but scarcely at all constricted near the apex, very deeply, densely
sculptured, the sculpture consisting of moderately small reniform punctures,
close-set and often coalescent, with the narrow interspaces more or less punc-

prothorax, fully two and one-half times as long, elongate-ogival, the sides
becoming parallel and nearly straight in basal half; striae distinct, obsoletely
punctate. Length 2.1-2.25 mm.; width 0.9-1.0 mm.
Virginia ; Indiana ; Texas.
A common species, allied to tychioides, but abundantly distinct
in its much smaller, more coarsely and densely sculptured protho-
rax and very different beak, also in the shorter second funicular
joint, and sparser and narrow scales of the metasternum.

rather small, not very deep and slightly oval, the interspaces finely piinctu-
late ; scales whitish, narrowly oval, dense ; legs bright rufous, the tarsi
darker. Head minutely punctate ; constriction strong ; beak rather thick,
feebly arcuate, densely punctate in basal half, the apical regions sparsely so
and shining, equal in length to the head and prothorax ; antennje inserted
slightly beyond the middle, the basal joint of the funicle not quite as long as
the next three, second one-half longer than the third. Prothorax large, not
quite as long as wide, the sides rounded before the middle, thence feebly con-
vergent and nearly straight to the base, very deeply constricted at some dis-
tance behind the apex, the latter tubulate and barely three-fourths as wide as
the base ; disk widest before the middle. Elytra at base two-fifths wider than
the prothorax, two and one-half times as long, not quite one-half longer than
wide, the sides straight and parallel in basal half, then narrowly parabolic ;
strise fine, deep, scarcely at all impressed and with elongate narrow punctures
laterally. Length 2.0 mm. ; width 0.9 mm.
California (Napa Co.).
The single specimen, which I took at Suscol Station, is almost
entirely denuded above, with only a small spot of white scales near
the middle of each elytron and others yellowish in color scattered
thence to the apex ; the two spots are unsymmetrical and therefore
simply remnants of the vestiture ; the specimen is probably a female.
The beak is sparsely and rather finely setulose, with a small abrupt
tuft of white squamules above each eye. This species is easily
separable from obtectus by its shorter, more obese form and red
legs, from cinereus by its large prothorax, and from both by the
ditterent sculpture of the pronotum.

Oblong-oval, convex, black throughout, the legs rarely with a
feeble piceous tinge ; integuments densely clothed with elongate-
oval dark brown and cinereous scales, confusedly and not conspicu-
ously mottled on the elytra, the surface polished black when de-
nuded, the pronotum rather finely but very deeply and closely punc-
tate, the punctures not in actual contact, perforate. Beak differing
scarcely at all in the sexes, short, thick, strongly, densely punctate,
sparsely squamulose, with two erect tufts at base, very feebly arcuate
and but very slightly longer than the head and prothorax ; antennae
inserted near apical third in the male and two-fifths in the female,
the basal joint of the funicle fully as long as the next three, second
barely longer than the third. Prothorax but slightl}" wider than
long, the sides broadly arcuate, broadly, feebly constricted behind

Elytra at base one-half wider than the prothorax, very nearly three
times as long-, one-half to three-fifths longer than wide, straight and
parallel at the sides in basal half to three-fifths; striae fine, deep,
distinctly punctured toward the sides. Length 2.1-2.7 mm.; width
0.9-1.2 mm.
California (San Francisco), abundant. The commonest species
of the middle coast regions of California, and easily known by the
characters given. I cannot perceive that the elytra are notably
elongate in this species, as remarked by LeConte, but the very
feeble sexual difference in the beak is a distinguishing character.
32 S. apionides n. sp. — Narrowly oblong-oval, convex, deep black
throughout the body, legs and antennae ; vestiture sparse, consisting of small
remote setiform squamules on the elytra, with small sparse condensed spots
of wider white scales, the latter also more abundant on the pronotum toward
the sides ; under surface sparsely and unevenly squamose. Head finely granu-
lato-reticulate, the transverse impression feeble but distinct ; beak in tlie male
short, thick, feebly arcuate, dull and granulose, punctate, sparsely setulose,
not fasciculate at base, very slightly longer than the head and prothorax, with
the antennae inserted just beyond the middle, in the female nearly similar,
slightly longer, scarcely thinner. or more arcuate, smoother and more shining
tliroughout, distinctly longer than the head and prothorax and fully one-half
as long as the elytra, with the antennae inserted at the middle ; antennae
moderate, the second funicular joint but very slightly longer than the third.
Prothorax slightly wider than long, convex, the sides broadly, evenly arcuate,
becoming more convergent and nearly straight near the apex, the latter three-
fourths as wide as the base ; constriction almost completely obsolete ; punc-
tures coarse, very deep, coalescent in threes or fours forming oblique sinuous
lines. Elytra at base three-fifths wider than the prothorax, three times as
long, three-fifths longer than wide, the sides nearly straight and parallel in
basal half, the posterior half subacutely ogival ; striae rather fine, deep toward
the suture but becoming simply series of coarse elongate punctures laterally.
Length 1.6-1.75 mm. ; width 0.6.5-0.7 mm.
North Carolina (Asheville).
A very distinct minute species, represented in my cabinet by a
single pair. It may be recognized by the sparse and uneven vesti-
ture, and the coarse deep and peculiar sculpture of the pronotum.
33 S. perpusillllS n. sp. — Oblong-oval, convex, blackish- piceous ; legs
rufous with the tarsi darker ; vestiture consisting of oval white scales, moder-
ately large and generally not quite contiguous, and, on the pronotum, decidedly
separated and varying in width ; recurved setae of the elytra fine distant and
not conspicuous ; scales of the under surface small, rounded, white, very nar-

rowly separated. Head scarcely shining, the frontal constriction very broad
and feeble ; beak slender, cylindrical, smooth and extremely minutely, feebly
punctulate in apical half, punctate and sparsely squamose toward base, dis-
tinctly longer than the head and prothorax and nearly three-fifths as long as
the elytra, evenly and distinctly arcuate ; antenna inserted at the middle,
rather short, the second funicular joint but slightly shorter than the next two.
Pi-othorax very nearly as long as wide, the sides broadly, evenly arcuate toward
base, becoming slightly more convergent and nearly straight anteriorly, the
constriction very feeble ; punctures small, shallow and not dense ; interspaces
shining. Elytra at base one-half wider than the prothorax, two and two-thirds
times as long, one-half longer than wide ; sides nearly straight, and parallel
in basal half, then convergent, the apex acutely rounded ; striae fine but deep.
Length 1.6 mm. ; width 0.6 mm.
Florida.
The unique type is a female and the species is not closely allied
to any other known to me, being easily determinable by its small
size and white scales, the latter close-set but generally not quite
contiguous.
34 S. defl'icans n. sp. — Narrowly oblong-oval, convex, black, the legs
dark rufous, the tarsi piceous ; upper surface clothed unevenly with moder-
ately large oval whitish scales, generally denser, or at least more persistent,
in a broad line from the humeri to the middle of each elytron ; stout recurved
bristles short. Head dull, densely granulose ; transverse impression rather
feeble; beak opaque, shining and finely, deeply sulcate in apical half, sparsely
setulose toward base, densely so above the eyes, very feebly arcuate, stout,
tapering, as long as the head and prothorax ; antennae inserted at apical two-
fifths, the basal joint of the funicle rather robust, as long as the next three,
second nearly one-half longer than the third. Prothorax very nearly as long
as wide ; sides subparallel and broadly arcuate, convergent and very feebly
constricted near the apex, the latter three-fourths as wide as the base ; disk
subopaque, finely, rather feebly and moderately densely punctate, the inter-
spaces minutely, very densely, deeply punctulate. Elytra at base not quite
one-half wider than the prothorax, scarcely three times as long ; sides straiglit
and parallel in basal three-fifths, then parabolically rounded ; striae fine but
deep, the surface polished when denuded. Legs moderate, the tarsal claws
very small, connate in basal half. Length 1.4-1.8 mm. ; width 0.6-0.7 mm.
California (Lake and Monterey Cos.).
The three specimens in my cabinet exhibit but slight variability
and are of uncertain sex ; it is probable that the sexual differences
in the beak are, however, very slight. This species is not closely
allied to any other, and is easily distinguishable, among the Cali-
forniau forms, by its minute stature.
Coleopferological Notices, IV. 407
35 S. giljliirostris n. sp. — Stout and convex, oval, black, the legs except
near the base rufous ; elytra pale rufous, narrowly blackish along the suture ;
upper surface sparsely and unevenly clothed with yellowish scales and fine
slender squamules, the former dense at the sides of the pronotum toward base
and narrowly along the middle, and on the elytra in subtransverse uneven
spots and fasciae ; under surface moderately densely squamose. Head polished,
the constriction evident ; beak in the male moderately thick, very feebly,
evenly arcuate, dull, densely punctate, strongly gibbous before the constric-
tion, a little longer than the head and prothorax and about one-half as long
as the elytra ; antennae inserted at apical two-fifths, the second funicular joint
but slightly longer than the third. Prothorax moderately large, quite distinctly
wider than long, the sides subparallel, broadly, rather strongly arcuate, con-
vergent and broadly sinuate toward the apex, the latter three-fourths as wide
as the base; disk convex, dull, very densely punctate, the punctures small,
deep, lunate, the interspaces densely punctulate. Elytra at base not more
than one-third wider than the prothorax, two and one-half times as long, about
one-fourth longer than wide, just visibly wider behind the middle than at base,
the sides straight, broadly parabolic in apical two-fifths, the strise deep and
distinct. Length 1.9 mm. ; width 1.0 mm.
Delaware.
The single male represents a species allied somewhat to sculpfi-
collis, but diifering in its larger, more densely sculptured pronotum,
much shorter elytra, gibbous beak and different vestiture, the sides
of the pronotum being simply sparsely, finely squamulose, and the
third elytral interval conspicuously squamose at base in sculjyii-
coUis.
3G S. sqiialidlis n. sp. — Stout, strongly convex, oval, black, the legs
dark rufo-piceous ; vestiture of the upper surface dense, consisting of rather
large imbricated scales, confusedly mottled whitish and piceous, the former
generally predominating ; scales of the under surface very small, rounded,
yellowish-white and extremely dense ; recurved setfe sparse and slender.
Head feebly squamulose anteriorly, the constriction moderate ; beak in the
male thick, very feebly arcuate, rough, densely punctate, sparsely hispid and
dull almost throughout, much longer than the head and prothorax and one-
half as long as the elytra, with the antennae inserted at apical third, in the
female longer, more. slender and arcuate, finely, rather densely punctate but
shining and nearly glabrous in apical half, nearly three-fourths as long as
the elytra, with the antennae inserted at the middle ; basal tufts not well
developed ; antennae rather slender, the second funicular joint three-fourths
as long as the first and equal to the next two in the female, very little shorter
in the male. Prothorax rather large and inflated, the sides strongly arcuate,
convergent and rather strongly constricted near the apex, the latter not more
than three-fifths as wide as the middle ; disk convex, rather coarsely, deeply,
extremely densely punctured, one-fourth wider than long. Elytra at base not
more than one-third wider than the prothorax, two and two-thirds times as

parabolic in apical half. Length 2.3-2.7 mm. ; width 1.2-1.4 mm.
Pennsylvania ; District of Columbia ; Indiana.
A common eastern form resembling ovipennis but much larger,
with a relatively larger, more inflated prothorax, more elongate
beak and longer second funicular joint. I found it labeled "amoe-
?iHs" in my cabinet, a mistake which may possibly be common ;
amoeniis is a widely different species, with the prothorax scarcely
perceptibly narrower than the base of the elytra. One specimen
before me is labeled "Arizona," but perhaps erroneously.
37 S. OTipennis Lee. — Proc. Am. Phil. Soc, XV, p. 170.
Oval, strongly convex, stout, black, the legs rufescent; scales of
the upper surface moderately large, very dense, confusedly mottled
with whitish and different shades of brown or piceous, the white
scales usually more numerous and forming a distinct line at the
base of the third interval. Beak in the male rather stout, densely
squamosa, a little longer than the head and prothorax ; antennae
inserted at apical two-fifths, the second funicular joint but slightly
longer than the third. Prothorax small, slightly but quite distinctly
wider than long, the sides evenly, rather strongly arcuate, conver-
gent and very feebly constricted anteriorly, the apex fully three-
fourths as wide as the base; disk densely, strongly punctate. Elytra
at base nearly one-half wider than the prothorax, almost three times
as long, barely one-fourth longer than wide, distinctly wider in the
middle than at base, gradually, acutely ogival in apical half; striag
indicated by coarse and uneven partings of the vestiture. Ijcngth

description is slightly too great.
PROmECOTARSUS n. gen.
I have separated under this name three species closely allied to
Smicronyx, but differing in the longer, more glabrous tarsi, having
a smaller third joint, with the fourth joint very long and subequal
in length to the entire remainder. In general appearance the species
are more cylindrical than in Smicronyx, and more nearly resemble
Endalus. The principal characters may be expressed as follows : —
Body cylindrically convex, the elytra but very slightly wider than the pro-
thorax, the vestiture dense, consisting of small, imbricated, almost completely
Coleopferological Notices, IV. 409
non-stn'gose scales, with a series of recurved, subrecumbent setse on each strial
interval. Beak constricted at base, the head nearly spherical, eyes as in
Smicronyx. Prothorax constricted at apex, the ocular lobes more or less dis-
tinct. Scutellum very small. Prosternum deeply sinnate at apex. Metaster-
num as long as the first ventral segment. Abdomen flat, sutures two to four
equally and feebly recurved at the sides, the second segment barely as long
as the next two and not quite as long as the fifth. Legs, excepting tarsal
structure, nearly as in Smicronyx.
In this genus, which constitutes one of the intermediate forms
connecting Smicronyx with the Hydronomi, the claws are long and
generally widely divergent, but in one species become subparallel ;
they may be described as connate very near the base, with the
suture distinct. Promecotarsus is clearly, therefore, a transitional
form but must be classed with Smicronyx, these two genera consti-
tuting the group Smicronychi.
The species may be easily known as follows : —
Ungues widely divergent ; prothorax very nearly as long as wide ; ocular
lobes not prominent.
Prothorax abruj^tly, deeply constricted near the apex, the latter but slightly
narrower than the base 1 iMaritinius
Prothorax gradually more strongly narrowed and broadly, feebly constricted
toward apex, the latter scarcely more than two-thirds as wide as the base.

1 P, maritilllllS n. sp. — Subcylindrical, convex, piceous, the legs feebly
rnfesceut with tlie tarsi black ; vestiture very dense, pale, the broad recurved
squamules very short and subrecumbent. Head shining, glabrous, the trans-
verse groove deep ; beak in the male moderately thick, densely, rugosely
punctate, sparsely squamulose, abruptly, strongly bent at the antennae, thence
more shining and feebly tapering to the apex, fully as long as the head and
prothorax ; antennae inserted at apical third, the funicle long, the basal joint
as long as the next two, second almost as long as the third and fourth, outer
joints a little longer than wide, not noticeably thicker, club very slender, fusi-
form, the basal joint almost glabrous. Prothorax nearly one-fourth wider than
long, parallel and broadly, evenly, rather strongly arcuate at the sides, deeply
constricted behind the apex, the latter transversely truncate and but slightly
narrower than the base ; disk feebly convex, very densely, not coarsely, sub-
rugosely punctate. Elytra at base but slightly wider than the prothorax,
rather more than twice as long, fully two-fifths longer than wide, the sides
subparallel and nearly straight in basal three-fifths, the apex narrowly para-
bolic ; striae deeply impressed. Legs^ moderate, the tarsi as long as the tibi;e.
Length 2.0-2.2 mm. ; width 0.8-0.95 mm.

California (San Diego). Mr. Chas. Fuchs.
The three specimens in my cabinet are males, and the beak is
probably much longer and more evenly arcuate in the female. This
species somewhat resembles densus, but is smaller, narrower and
differs greatly in the form of the prothorax, as well as in the some-
what longer second joint of the antennal funicle.
2 P. densus n. sp. — Robust, subcylindrical, convex, black, extremely
densely clothed with rather small, broadly oval, yellowish-white and uniform
scales, which are widely overlapping, granulose in texture and not strigose,
similar in structure and density on the under surface ; recurved setse distinct.
Head glabrous, finely, strongly reticulate ; constriction fine, deep ; beak in the
female slender, polished, exceedingly finely, remotely punctate, but thicker,
dull and rugosely punctate near the base, nearly evenly and quite strongly
arcuate, almost three-fifths as long as the elytra ; antennae inserted scarcely
beyond basal third, rather long and slender, the second funicular joint about
as long as the next two ; club moderately robust, very sparsely pubescent
and shining toward base. Prothorax but slightly wider than long, the sides
parallel and very feebly arcuate in basal two-thirds, then moderately conver-
gent and broadly constricted to the apex, the latter rather more than two-
thirds as wide as the base ; disk moderately convex, evenly, densely squamose,
finely, very densely punctate throughout. Elytra at base but slightly more
than one-fourth wider than the prothorax, not quite two and one-half times
as long, one-half longer than wide, the sides parallel in basal three-fifths,
then narrowly angulato-parabolic ; strise indicated by fine but sharply defined
partings of the dense crust of scales. Legs somewhat stout, the tarsi long and
slender, the third joint only moderately dilated, the last joint long ; claws
long, divergent, connate at base. Length 2.5 mm. ; width 1.05 mm.
Nebraska.
Easily distinguishable by the dense and uniform crust of non-
strigose imbricated scales and the subcylindrical form, as well as by
the characters given in the table.
3 P. fuiuatus n. sp. — Moderately robust, convex, subcylindrical, black
throughout, extremely densely clothed with a crust of widely overlapping,
dark, yellowish-gray scales, uniform in color, very broad and excessively
minutely, indistinctly strigilate ; recurved setse fine but distinct. Head gla-
brous, minutely, feebly reticulate and rather strongly shining, the constriction
tine but moderately deep ; beak in the male thick, evenly cylindrical, distinctly
arcuate, moderately densely punctate, not quite as long as the head and pro-
thorax, with the antennae inserted just beyond the middle, in the female a
little more slender, evenly, distinctly arcuate, smooth and remotely punctulate
except near the base, scarcely visibly longer than the head and prothorax,
barely one-half as long as the elytra, with the antenna inserted at basal two-
fifths ; antennae moderately slender, the second funicular joint as long as the

next two ; club slender, gradually, acutely pointed, ratlier densely pubescent.
Prothorax transverse, one-third to two-fifths wider than long, the sides parallel,
broadly, evenly arcuate in basal two-thirds, then strongly convergent and
deeply, abruptly constricted, the apex transverse between the very prominent
ocular lobes; disk very densely squamose, the sculpture dense and subrugose
when denuded. Elytra at base between one-third and one-fourth wider than
the prothorax, fully three times as long, one-half longer than wide, the sides
parallel and nearly straight in basal three-fifths ; striae indicated by clearly
defined narrow partings of the vestiture. Length 2.2-2.3 mm. ; width 0.95 mm.
Montana (Helena). Mr. H. F. Wickham.
Closely allied to densus, but differing in its much shorter pro-
thorax, shorter beak in the female, with the antennsB distinctly less
basal, in its gray and not ochreous vestiture and in many other
minor characters. It was taken in abundance, and the six speci-
mens before me are very uniform in size.
Tychiini.
TYCHIUS Schcinh.
In subdividing the comparatively few American representatives
of this genus, I have made use of some characters which do not
exist among the European species, or at least, which have apparently
not been mentioned in systematic works. Our species may be
readily divided into four subgeneric groups as follows: —
Antennal funicle 7-jointed.
Body more or less robust and oval, the elytral intervals entirely devoid of
recurved setae I
Body narrower, oblong ; elytral intervals with recurved semi-erect setae. ..II
Antennal funicle 6-jointed.
Body elongate-oval, with robust recurved setae, the entire facies almost as
in group II; eyes large, very nearly circular IH
Body much smaller, the species generally minute, with or without erect
setae; eyes more or less transversely fusiform IV
None of these divisions seems to correspond exactly with the
European Miccotrogus, although I am not certain of the habitus of
that subgenus, specimens sent to me by M. Desbrochers under the
name M. jncirosti-is having the antennal funicle certainly 7-jointed.
It can be confidently affirmed, however, that the structure of the
funicle is without full generic significance in our species, for the
reason that groups II and III agree so satisfactorily in all other
structural features. At the same time, there is sufficient hete-
rogeneity to warrant a division into subgenera on the lines above
Annals N. Y. Acad. Sci., VI, Aug. 1892.— 28
412 Goleopterological Notices, IV.
suggested. There is nothing to indicate that Miccotrogus possesses
greater systematic value than any one of these American groups.
The species may be easily recognized by the following charac-
ters : —
Subgenus I.
Elytral vestiture narrowly vittate, often alternating fulvous and cinereous on
the intervals, the strise broadly visible ; anterior tibiae of the male strongly,
acutely toothed internally near the middle 1 liiieellllS
Elytral vestiture nearly uniform in color, the striae indicated by fine and in-
distinct i^artings ; anterior tibiie not dentate in the male.
Beak thick, only feebly diminishing in diameter from base to apex.
Body broadly oval, the scales very narrow and hair-like 2 sordidus
Body more narrowly oval, the scales broader and more densely crowded.
3 tectus
Beak thick at base, rapidly and finely attenuate toward apex ; elytral ves-
titure mingled with a vei-y few widely scattered rounded scales toward
apex 4 arator
Subgenus II.

Setfe borne by the strial punctures of the elytra long semi-erect white and
conspicuous.
Prothorax less transverse, with a broad median vitta which is entirely
clothed with large white imbricated scales ; setre throughout the body
robust 5 SOltaili
Prothorax strongly transverse, with a very fine white median line which
contains no large non-strigose scales, except in the broader portion near
the base; setse throughout longer and fine (J llirtellllS
Setse borne by the strial punctures short, thicker, recumbent and incon-
spicuous 7 aratus
Abdomen densely squamose but without trace of setse ; scales of the elytra
smaller and more densely imbricated along the suture than elsewhere.
Beak very feebly narrowed toward apex ; prothorax a little less transverse,
wider at tlie middle than at base ; elytra with many more setse than scales
on the disk 8 seniisqaniosiis
Beak rapidly and finely acuminate, thicker toward base ; body stouter ;
sides of the prothorax parallel behind ; elytra with many more large
whitish oval scales than setae 9 lailiellosiIS
Subgenus III.
Beak short, feebly tapering from base to apex ; elytra with large imbricated
scales and very robust recurved fulvous setae 10 pi'Olixus
Subgenus IV.
Elytra without long erect bristles, although sometimes with abundant short
strongly recurved seta;, which are not very conspicuous.
Coleopterological Notices, IV. 413
Vestitiire finely and feebly variegated in color, and with a large sutnral
spot of white imbricated scales behind the scutellum...ll Ta.riega.tllS
Vestiture nearly uniform in color, the scales of the npper surface all narrow
and elongate, the squamules borne by the strial punctures similar to
the others or very nearly as wide.
Elytral intervals each with a single nearly even series of narrow scales,
fulvous to white in color 12 simplex
Elytral intervals confusedly clothed with scales throughout their width.
Elytral scales evenly but not very densely distributed, narrow and
slender, oclireous-yellow in color, the middle scales of each interval
semi-erect, especially toward apex 13 sibillioides
Elytral scales broader and more closely recumbent, denser along the
suture, more broadly so behind the middle 14 mica
Elytra with stiff straight and strongly hispid erect or inclined setse.
Elytra with large rounded or oval whitish scales, unevenly distributed.
Elytral setse long and rather slender 15 setosus
Elytral setse short, broad and scale-like 16 Sll1)fasciatlis
Elytra with long slender white and fulvous decumbent squamules, entirely
without rounded scales ; erect setse rather fine and much more numerous.
17 Iiispidiis
The species of groups I and lY are generally taken in abundance
when discovered, while those of II and III are apparently much
less plentiful in individuals, or possibly less gregarious; they are
also a little more closely allied among themselves, forming a more
difficult study.

1 T. lineellus Lee— Proc. Am. Phil. Soc, XV, p. 217.
Broadly oval, strongly convex, rather densely clothed above with
long, slender, coarsely strigose scales, which are variable in color,
and, to some extent also, in distribution; in the best marked speci-
mens they are subcupreous in two broad pronotal vittte, and on the
alternate intervals of the elytra, elsewhere cinereous, but often
cinereous throughout; on the under surface they are whitish,
liroader, non-strigose and feathery in structure. The male has the
beak short, abruptly tapering beyond the antennae, and the ante-
rior tibiiB strongly, acutely toothed internally just beyond the
middle; in the female the beak is longer, nearly straight, slender
but abruptly thicker very near the base. Length 3.7-4.7 mm. ;
width 1.7-2.2 mm.

twice as long. Posterior femora feebly toothed. Length 4.0-4.7
mm. ; width 2.1-2.4 mm.
Iowa and Illinois. Our largest species, sufficiently common and
very readily recognizable by the characters given. The three speci-
mens before me are probably males; in the female, the antennae
are undoubtedly less apical.

fifths; intervals without median line of squamules, the hairs of the
strial punctures white and quite evident. Length 2.6-3.7 mm.;
width 1.15-l.T mm.
Colorado and Montana. Numerous specimens. In one female,
not otherwise differing, the beak is deformed, the apical parts being
swollen polished and impunctate, separated from the post-aniennal
portion by a broad depression. The same deformity exists to a less
marked degree in a male specimen, and the species seems to be
peculiarly liable to this kind of rostal malformation. An extremely
feeble transverse impression at the antennas is however apparently
normal in some species, such as aratus Say.

Oblong-oval; rather stout, convex, black, the legs piceous; an-
tennas and apical parts of the ))eak rufo-testaceous ; body very
densely clothed throughout with elongate dark ochreous scales,
which are coarsely strigose, but intermixed with a few larger ones,
toward the apex of the elytra, which are non-strigose in structure
and rather paler in color ; intervals of the elytra without setas, the
strial squamules distinct. Beak thick, tumid, densely punctured
and squamulose behind, but very thin, glabrous, shining and
sparsely punctured before, the point of antennal insertion, feebly
arcuate, the thin apical portion straight, rather shorter than the
prothorax in both sexes but a little longer in the female than in the
male, the antennas inserted at the middle in the former and at
apical two-fifths in the latter, with the basal joint of the funicle as
long as the next two, the second two-thirds as long as the first.
Prothorax two-fifths wider than long, the apex much loss than
one-half as wide as the base. Elytra distinctly wider than the pro-
thorax in both sexes, one-half longer than wide. Length 3.0-3.0

W3'oming (Laramie).
A rather narrow species, allied to hirfelhis and differing- in the
broad vitta of white scales along the middle of the pronotum, the
more elongate prothorax, shorter, much coarser semi-erect seta*
above and on the abdomen, and in the generally narrower form of
the body. The single male was taken by Mr. Hugo Soltau.

the pronotum slender, strongly strigose, converging obliquely back-
ward, fulvous, but whitish along the middle and laterally near the
base ; those of the elytra very large, broad, widely imbricated,

Moutana. The type specimen, Avhich appears to be a male,
agrees so thoroughly with the description of Say, that there can
be little doubt of its representing the true arafus. It is unfortu-
nate, however, that there should be two names in the same genus
and within the same faunal limits which are mutually so similar.
The term "olivaceous," applied by Say to the color of aratus,
might have wide limits of meaning.
8 T. semisqnailiosus Lee. — Proc. Am. Phil. Soc, XV, p. 217.
Narrowly oblong-oval, rather convex, piceous, the legs, antennae
and tip of beak rufcscent ; vestiture complex, consisting of narrow
elongate fulvous squamules on the pronotum, which become broad
Avhite scales in the middle and at each side but only near the base,
anteriorly there are also some widely scattered large brown scales;
on the elytra the intervals are clothed throughout with stout re-
curved and subrecumbent brown setae, among which there are very
sparsel}^ strewn large dark gray-brown scales, the latter dense im-
bricated and reddish along the sutural interval ; on the under surface
the scales are whitish, elongate-oval and dense throughout. Beak
in the male short, thick, not as long as the prothorax, feebly taper-
ing from base to apex, densely squamulose except near the tip, the

rax, three times as long, the sides straight and parallel in basal two-
thirds ; striae fine, impressed, with the white squamules distinct.
Length 2.5 mm. ; width 1.0 mm.
California. This species can be easily identified by the narrow
form, sparse scales of the elytra except along the suture, and absence
of erect ventral hairs. The large scales of the upper surface are, as
usual, granulose in structure and not strigate.
9 T. lamellosus n. sp. — Rather broadly oblong-oval, convex, piceous,
the tibise, antennae and tip of beak rufescent ; vestiture dense and varied,

ally intermixed toward the sides and almost replaced by large whitish scales,
also narrowly along the middle, more broadly toward base ; on the elytra the
non-strigose scales are very large, broad, ogival, pearly white in color, dense

along the middle and lateral edge of each elytron, also dense and more yellow-
ish along the sutural interval; recurved fulvous setse rather abundant; on
the under surface the scales are elongate-oval, whitish and dense. He<id and
beak very densely, finely squamulose, the latter short, very stout, strongly
tapering from base to apex, with the portion beyond the antennae very thin,
nude and shining, feebly arcuate, in the male not more than three-fourths as
long as the prothorax, with the antennse inserted just behind apical third, the
first joint of the funicle very stout, pedunculate at base, not as long as the

The single male before me represents a species allied to semi-
sqiiamosus, but differin.ij- in its more robust form, much more abun-
dant and whiter scale-like plates of the elytra, relatively narrower
apex of the prothorax, more rapidly and finely acuminate beak, and
in several other characters. The fifth ventral segment has in the
center a small deep punctiform fovea, which is not visible in the
male of semisquamosus.

10 T. prolixiIS n. sp. — Oblong-elongate, convex, blackish, tlie antennfe
and tip of beak paler ; vestiture very dense throughout, consisting, on the
pronotum, of long slender subrecumbent and strigose squamules, pale fulvous

intermixed with more slender and erect setae but with a few broad non-strigose
scales in the whitish areas, though only near the base ; on the elytra the
scales are very large, dense, rounded, finely granulose in texture, widely im-
bricated and dark reddish-gray in color, each interval with a single uneven

Nevada.
The six-jointed antennal funicle isolates this species from all
others which it most resembles in external aspect. The single type
specimen is a male, and has the fifth abdominal segment scarcely
impressed but longer than the two preceding together, the second
suture flexed strongly backward at the sides extending a little be-
yond the anterior margin of the fourth segment, the third and fourth
sutures scarcely at all bent at the sides.

11 T. variegatus n. sp. — Robust, oblong, rather convex, blackish, the
antenna and beak slightly paler ; vestiture above not very dense, on the pro-

The large series before me indicates but slight variability, and
the characters given above will readily serve to identify this species,

peculiar to the desert regions of Arizona.
12 T. simplex n. sp. — Oblong-oval, rather convex, piceous, the elytra
more or less rufesceiit ; beak rufous except near the base ; vestiture moderately

Length 1.4-1.7 mm. ; width 0.7-0.9 mm.
Texas (El Paso); Arizona (Benson and Tugson).
Of this distinct species I have a large series, the principal varia-
tion being in the color of the squamules of the pronotum and median
series of the elytral intervals.
13 T. silJiiiioides n. sp. — Robust, oblong-oval, convex, piceous, the legs,
antennse and beak rufous ; vestiture of the iipper surlace nearly uniform,
consisting of long slender ochreous-yellow strigose squamules, without trace

Arizona (Santa Rita Mts.). Mr. H. F. Wickham.
The elytra have a very small sutural notch, but are not individu-
ally broadly rounded as they are in Sibinia. This peculiar type
is well represented in Brazil. Four specimens.
14 T. mica n. sp. — Oblong-oval, rather convex, rufo-piceous throughout ;
vestiture moderately dense, generally whitish, pale brown on the disk of the
pronotum, consisting throughout, on the upper surface, of parallel but rather
broad strigose recumbent scales, rather dense on tlie pronotum, becoming
broader and whiter on the flanks but not different in structure and without
trace of intermixed setae or broad rounded scales ; on the elytra similar, re-

beneath. Length 1.5 mm. ; width 0.7 mm.
Arizona.
This species is not closely allied to any other, but is represented
by a singe rather imperfect male example. It is easily distinguish-
able by the uniform structure of the parallel strigose scales of the
upper surface, and by the absence of erect bristles.
15 T. setosus Lee— Proc. Am. Phil. Soc, XV, p. 218.
Oblong-oval, moderately convex, more or less pale piceo-rufous ;
vestiture uneven, consisting of small subrecumbent robust setas.
Coleopterological Notices, IV. 423
sparsely scattered throughout the upper surface, intermixed with
large rounded non-strigose scales of a whitish tint, especially no-
ticeable on the prothorax except in a large, more or less distinct
spot toward base on each side of the median line, and on the elytra
in a large rounded or subannular sutural spot before the middle,
along the sutural interval and near the humeri and subapical um-
bones ; the alternate strial intervals with a single series of long-
stiff erect and widely spaced sette ; under surface densely clothed
with large whitish scales. Beak rather long and slender, squamose
but only just visibly thicker toward base, distinctly longer than the
head and prothorax ; antennae inserted just beyond the middle, the
first funicular joint not as long as the next three, second and third
subequal, both longer than wide. Prothorax small, one-third wider
than long, constricted behind the apex. Elytra two-fifths wider
than the prothorax and a little less than three times as long, one-
third longer than wide. Posterior femora unarmed, rather slender.
Length 1.35-1.8 mm.; width 0.65-0.8 mm.
California (Yuma); Arizona (Benson and Tugson). A rather
abundant species, easily recognizable by the mixture of large
rounded unevenly distributed scales and long stiff erect setae,
bristling on the elytra. Although the ample series before me
shows great variation in size, I am unable to detect any sexual
differences in the structure of the beak.
16 T. S1l1>fasciatlis n. sp. — Oblong-oval, moderately convex, dark
red-lirown ; tip of beak pale rufous ; antennal club black ; vestiture com-
plex, uneven in distribution, consisting of short subrecumbent and very
robust setae and larger rounded whiter scales, the latter especially evident
on the elytra along the entire sutural interval and in a wide feebly defined
vitta from the humeri to the subapical umbones, also in a conspicuous trans-
verse area, wider and subannulate toward the suture, situated scarcely before
the middle of the length ; the alternate strial intervals with a single series of
short, erect, very stout and widely spaced setae ; under surface densely clothed
with large rounded concave and whitish scales. Head covered with large
umbilicate scales, the beak moderately stout, feebly, evenly arcuate, very
feebly tapering from the base, a little longer than the head and prothorax,
densely squamose except beyond the antennae, the latter inserted at apical

Prothorax two-fifths wider than long, the sides convergent from base to apex
and feebly arcuate, the subapical constriction feeble ; apex nearly three-
fourths as wide as the base. Elytra one-third wider than the prothorax
and fully three times as long, two-fifths longer than wide, parallel at the
sides in more than basal half, obtusely rounded behind ; striae coarse, punc-

slender, the femora not dentate. Length 1.6-1.7 mm. ; width 0.75 mm.
Texas (Big Spring-s). Mr. H. F. Wickham.
Allied to setosus, but easily distinguishable by the somewhat
smaller scales of the upper surface, shorter and stouter erect seta?,
and by the shorter, rather thicker beak and longer elytra. In both
of these species the erect bristles are confined to the alternate inter-
vals, except toward apex. Sexual differences are not evident, even
in the length or structure of the beak. The third and fourth ven-
tral sutures are almost obliterated by the dense crust of scales, but
appear to be sinuate near the sides, although not flexed backward
to any noticeable extent. Four specimens.
17 T. IlispidUS n. sp. — Oblong-oval, rather convex, piceous, elytra,
except on the suture, more broadly toward base, legs, beak and antennae,
rufous ; vestiture moderately dense, not very uneven, consisting, on the
upper surface, of long slender squamules, subrecumbent, whitish and pale
fulvous confusedly intermingled, evenly distributed over the pronotum and
entire width of the elytral intervals, and without trace of large rounded
scales ; all the elytral intervals throughout their length with single series
of long erect bristling setse, whitish in color and rather widely spaced ;
squamules of the strial punctures distinct, white ; under surface rather
densely clothed with large oval whitish scales. Bead finely squamulose, the
transverse impression subobsolete ; eyes transversely fusiform ; beak in the
male rather stout, very feebly tapering and slightly arcuate throughout,
squamulose except near the apex, about as long as the head and prothorax,
with the antennae inserted just behind apical third; in the female very
slightly longer, thick, squamulose and subinflated in basal half, very thin,
glabrous and cylindrical in apical half, the antennae inserted at the middle ;
antennfe rather short, the basal joint of the funicle subequal to the next
three, second one-half longer than the third. Prothorax one-fourth wider
than long, the sides very feebly arcuate, slightly constricted behind the apex,
the latter two-thirds as wide as the base. Elytra two-fifths wider than the
prothorax and very nearly three times as long, about one-half longer than
wide, suboval, the sides parallel and just visibly arcuate, gradually con-
vergent and more rounded toward apex, the latter less obtuse than usual.
Posterior femora unarmed. Length 1.4-1.8 mm. ; width 0.65-0.8 mm.
Arizona (Santa Rita Mts.). Mr. H. F. Wickham.
This inconspicuous species is somewhat allied to setosus and sub-
fasciatus, but only in possessing erect bristling setae, otherwise it
differs greatly in the entire absence of large rounded scales on the
upper surface, and in the strongly marked sexual characters of the
beak, the latter, somewhat unusually, being more rapidly and
Coleoj)terological Notices, IV. 425
strongly inflated toward base in the female than in the male,
nearly as in Centrinus hospes, which inhabits the same region.
My series consists of seven specimens,
THYSAXOCXEMIS Lee.
In this genus the sexual divergencies in the structure of the beak
are extremely pronounced and far more noticeable than in Tylop-
terus, with which it is closely allied ; the present forms may be
distinguished from Tylopterus, however, by the much coarser, less
dense and non-sericeous vestiture. The fringe of hairs of the front
tibiiB in the male is not a character of generic importance, and often
disappears completely. The five species in my cabinet may be
mutually distinguished by the following table: —
Elytral intervals subequal in width and prominence.
Body pale rufo-testaceous, the elytra with a broad, darker and generally
less densely squamulose band, narrowed toward the sutnre, often indis-
tinct ; sometimes also with a short angulate sutural band of paler scales
near apical third fl'axilli Lee.
Body piceous-black, the beak and legs rufous, the tibiie witli a narrow sub-
median band blackish, the femora dark except toward base; vestiture
strongly mottled with black and whitish, fulvous near the base of the
elytra especially near the humeri, and on the pronotum except toward
the sides and in the middle toward base ; on the elytra a wliitish band at
basal fourth and a narrower angulate band at apical third are especially
noticeable. Head squamose ; eyes separated by barely one-half of their
own width ; beak in the male short but rather thin, feebly arcuate, as
long as the prothorax, with the antennae inserted at apical third ; in the
female very thin, smooth, cylindrical, evenly, distinctly arcuate, as long
as the head and prothorax, with the antennte inserted at about the middle ;
antennse long, thefunicle slender, with the basal joint more than one-half
as long as the remainder, club robust, blackish, not as long as the pre-
ceding six joints. Prothorax one-half wider than long, narrowed in apical
third, the sides thence parallel and almost straight to the base. Elytra
nearly one-half wider than the prothorax, three times as long, parallel,
broadly rounded at apex, with the subapical umbones rather distinct.

Elytral intervals distinctly alternating in width, the wider rather more con-
vex and more densely clothed ; body uniformly pale oclireous-testaceous
throughout helTOla Lee.
In gi'ajjhica, which is a very isolated species, intermediate in
habitus between Thysanocnemis and Tylopterus, the pronotal ves-
titure is fulvous except narrowly along the median line and at the
sides toward base, where it becomes white, the white lateral area
curved inward just behind the middle of the disk, giving the appear-
ance of a transverse interrupted band.
Otidocephalini.
OTIDOC£PHALUS Chev.
Since the last revision of this genus by Dr. Horn (Proc. Am.
Phil. Soc, XIII, p. 448), several remarkable forms have been
discovered in Florida and our extreme southwestern territories.
In the memoir referred to, seven species were recorded as occurring
within the United States, and one other was subsequently added
by LeConte. Besides O. pet'/oratus, for which a separate genus
Coleopterological Notices, IV. 427
is proposed below, fifteen species are now brought to notice ; prob-
ably many more still remain unknown. Mexico appears to be the
principal focal centre of Otidocephalus, and, although well repre-
sented in Brazil, the genus would seem to be relatively less abun-
dant there, being largely replaced by Erodiscus.
The species are readily subdivided into well-marked groups based
upon femoral, rostral and ungual structure, size of the eyes and
nature of the vestiture as follows: —
Beak without dorsal excavation; femora dentate 2
Beak with a large and very deep excavation near the middle ; femora un-
armed 9
2 — Tarsal claws with a large, acutely angulate, internal lobe ; body with erect
setae 3
Tarsal claws broadly swollen within toward base, but not at all angulate ;
body entirely without erect setse 8
3 — Elytra with more or less dense recumbent vestiture in addition to the erect
sette, the pubescence tufted in structure 4
Elytra with sparser recumbent or subrecumbent and paler hairs, simjile in
structure and always confusedly distributed over the surface 5
Elytra with stiff erect white setcne, intermingled with longer, more slender,
blackish hairs, all forming single series on the intervals 6
Elytra with simple erect seta?, either black or whitish in color, forming single
series on the intervals 7
4 — Elytra each with four glabrous or subglabrous vitta?.
Vittae narrow and sharply defined, with a few scattered tufts only near the
apex 1 TittatU8
Vittse much wider, always with unevenly scattered pubescent tufts through-
out the length, punctured and indefinitely limited ; body smaller and
relatively stouter 2 nivosiis
Elytra without four subglabrous vittse.
Pubescence moderately dense, paler along the elytral suture and median
line of the pronotum 3 tilkei
Pubescence uniform in color throughout the upper surface, pale brownish-
cinereous, broadly dense on the elytral intervals, but denuded in a narrow
space on eacli side of the series of punctures, producing a multi-vittate
appearance ; dorsal setae very short 4 iiisigllis
5 — Elytra without well-defined series of punctures, confusedly and unevenly
punctate throughout 5 estriatlis
Elytra with impressed even series of coarse deep punctures.
Body very robust, the subrecumbent setfe coarse, abuiwlant, pure white and
very conspicuous ; pronotum sparsely, unevenly and not coarsely punc-
tate 6 egregius
Body narrow, the subrecumbent shorter hairs sparse, somewhat dark in
color and not very conspicuous ; pronotum coarsely and very densely
punctate 7 sci'Ol)icollis
Annals N. Y. Acad. Sci., VI, Sept. 1892.— 29
428 Coleopterological Notices, IV.
6 — Elytral series feebly impressed, coarsely, deeply and rather remotely
punctured 8 floridaiilis
•y — Eyes separated by much less than one-half of their own width.
Elytral punctures fine, the series not impressed on the disk, the setse con-
fined in great measure to the alternate intervals, except toward apex ;
body rather stout 9 laeTicollis
Elytral punctures coarser, the series just visibly impressed, the setse more
abundant and conspicuous, widely spaced along all of the intervals ; body
smaller and narrower 10 speculator
Eyes widely separated.
Elytra strongly infiated behind, the seta3 very sparse, rather short, whitish
in color and only distinct toward apex 11 niyrinecodes
Elytra but slightly wider behind the middle than at base ; setae numerous,
long, blackish in color ; strial punctures coarser.
Body stouter, the antennse rufous 12 riliicoriiis
Body slender, the antennae black 13 lliyriliex
S — Ferruginous, the elytra blackish in apical half or more ; body with short,
white, slender, sparsely scattered and recumbent squamules ; femoral
teeth very minute 14 dicIil'OIl!^
9 — Polished, black, the legs, beak and antennae piceous ; pronotum and elytra
glabrous, without erect setae, except a few borne from a series of punctures
along the apical margin of the former on the flanks, and, on the latter,
several toward apex, and one much longer and isolated on each side of
the soutellum 15 cavirostl'is
The division of the genus by the form of the prothorax is im-
practicable, as, in several species, this part is more or less cylindrical
in the male and obovate in the female, notably so in speculator.
1 O. vittatus Horn.— Proc. Am. Phil. Soc, XIII, 1873, p. 448.
Elongate-oval, strongly convex, black, polished, densely clothed
with white pubescence formed of recumbent tufted hairs ; each
elytron with four narrow, feebly convex, abruptly defined, glabrous
vittas and a much narrower uneven line very near the suture, the
glabrous vittai narrow, but slightly more than one-half as wide as
the pubescent stripes, and each with a series of small widely and
unevenly spaced punctures bearing short piceous seta?. Beak short,
thick, three-fifths to three-fourths as long as the prothorax, deeply,
unevenly punctate at the sides, the antennEe inserted at apical two-
titths in the female and but just visibly beyond in the male. Pro-
thorax coarsely, unevenly punctate, with a polished fusiform tumid
and almost entire median impunctate line. Elytra but slightly
wider behind the middle than at base, almost twice as long as wide.
Coleopterologicnl Notices, IV. 429
Legs rather stout, pubescent, the femora somewhat strongly toothed.
Length 10-8.3 mm.; width 2.5-3.0 mm.
Southern California. My series of five specimens indicates but
slight variability, and the species, which is one of the largest of the
genus, may be readily known by the narrow, abruptl}' glabrous,
polished vittre of the elytra.
2 O. iiivosilS 11. sp. — Oval, feebly siibeuneate, black, polished, densely
clothed with white recumbent pubescence formed of tufted hairs, intermingled
with short stiff sparse piceous setae, the elytra each with five subglabrous
vittse, the first adjoining the suture ; those of the disk fully two-thirds as
wide as the pubescent stripes, all more or less confusedly punctate toward
their lateral limits, and always unevenly and sparsely covered with tufted
pubescence. Head sparsely pubescent, densely so between the eyes which
are separated by but slightly less than their own width ; beak short, thick,
straight, coarsely, rugosely punctate, rather densely pubescent in tufts through-
out, three-fifths to three-fourths as long as the prothorax, the antennae inserted
at apical third in the male, the second joint of the funicle almost as long as
the first. Prothorax but slightly longer than wide, strongly inflated at about
the middle, the base and apex subequal in the male, but the former relatively
narrower in the female, coarsely, closely and unevenly punctate, with a sub-
entire tumid impunctate line. Scutellum densely tomentose^ Elytra at base
one-half to two-thirds wider than the base of the i^rothorax, slightly wider
behind the middle than at base, three-fourths longer than wide. Legs moder-
ate ; femoral teeth small, acute ; anterior tibiae obtusely strongly swollen or
subdentate within at the middle. Length (J. 0-6. 5 mm. ; width 2.4-2.6 mm.
Arizona (Peach Springs); Texas (El Paso).
This species is closely allied to vittatus, but differs constantly in a
number of structural features. The prothorax and elytra are )}oth
less elongate, and the subglabrous stripes of the latter are wider,
indistinctly limited and always more or less pubescent; the antenna'
are rather more apical in insertion, the femoral teeth smaller, and
the anterior tibise more strongly and angularly swollen within at
the middle. The size is noticeably smaller than in vittatus. Three
specimens.
3 O. Ulkei Horn.— Proc. Am. Phil. Soc, XIII, p. 449.
This species is described as being moderately deuseh' clothed with
pubescence, which is recumbent and composed of tufted hairs as in
vittatus and insignis, the vestiture paler along the middle of the
pronotum and elytra. The femora are minutely toothed. Length
(exclusive of the head) 6.5 mm.
Lower California. A single specimen in the cabinet of Mr. Henry
Ulke of Washington.

4 O. ilisigllis n. sp. — Rather robust, subcuneate, very strongly convex,
polished, black throughout, densely clothed with tufts of pale brownish-cine-
reous pubescence, rather denser and whiter beneath, especially on the sternal
parapleurse, semi-erect on the prouotum, where they are mixed with sparse,
anteriorly directed and erect black setae, becoming white on the flanks and
toward base, recumbent on the elytra and mingled with posteriorly-inclined,
short sparse and whitish setae, mixed with blackish near the apex, the elytral
intervals becoming abruptly glabrous near the series of punctures, producing
a narrowly multi-vittate appearance, the median line of the prouotum and the
elytral suture not at all paler. Head densely clothed with recumbent whitish
tufts between the eyes, concealing the sculpture, more sparsely so behind ;
eyes separated by fully their own width, feebly convex ; beak thick, one-half
as long as the prothorax, straight, not carinate above, coarsely punctured and
longitudinally, indefinitely sulcate and rugose toward the sides, sparsely
punctate on the disk toward apex, sparsely clothed with erect hispid setae ;
antennae inserted at apical two-fifths, the funicle densely hispido-setose, the
second joint nearly twice as long as wide, three-fourths as long as the first
and one-half longer than the third, club rather large, oval, extremely densely
clothed with short brownish pubescence. Prothorax one-fourth longer than

inflated at basal third, thence sinuate to the base ; disk coarsely, deeply, un-
evenly punctate, the punctures denser above, sparser on the flanks, with a
smooth impunctate median line in apical half. Scutellum rather large, tri-
angular, extremely densely clothed with white pubescence forming a tumid

only one-fourth wider than the disk, nearly two and one-half times as long,
not quite twice as long as wide, perceptibly wider behind the middle than at
base ; disk with unimpressed series of fine, unevenly and moderately spaced
punctures, the series but just visibly impressed near the lateral margin. Legs
long ; femora strongly toothed; tibiae arcuate toward base. Length 8.5 mm. ;
width 3.3 mm.
Texas (El Paso). Mr. G. W. Dunn.
The largest species which I have seen, and allied to ulkei in the
development of the remarkable tufts of setae, densely covering the
integuments ; each of these tufts is composed of three or four long
slender hairs, which are united and attached at base by a short stout
common foot-stalk. It differs from ulkei in the sculpture of the
beak, in the denser vittae of the elytra, uniform in color and not
paler at the suture, and in its larger size.
5 O. estriatllS n. sp. — Robust, extremely convex, shining, black, the
beak antennae and entire elytra more or less rufo-piceous but dark ; pubescence
simple, very sparse, recumbent, whitish, intermingled on the prouotum and
elytra, especially toward apex, with extremely few remote blackish setae ; under
surface rather sparsely clothed with long flexible whitish hairs, very dense on
Coleopterological Notices, IV. 431
the sternal parapleurse. Head coarsely, deeply, very densely pnnctate, tiat
and longitudinally rugose between the eyes, sparsely clothed with short
whitish hairs ; eyes large, rather convex, separated by four-fifths of their own
width ; beak thick, scarcely arcuate, not quite as long as the prothorax,
gradually, distinctly dilated toward apex, with two approximate eroded and
unevenly punctate grooves in basal half, sejiarated by a smooth impuuctate
line, laterally very coarsely, deeply, densely punctate and rugose but not sul-
cate, above toward apex strongly punctate and with two widely distant longi-
tudinal impressions ; antennae inserted at apical third, the second funicular
joint obconical, three-fourths as long as the first, club elongate-oval, densely
pubescent, darker in color. Prothorax very slightly longer than wide, the apex
broadly arcuate, a little wider than the base ; sides subparallel and nearly
straight in apical two-thirds, then gradually rounded, convergent and sinuate
to the base ; disk coarsely, deeply, unevenly and closely punctate, the punc-
tui-es becoming finer near the apex, sparse on the flanks toward base and with
a narrow subentire tumid impunctate line along the middle. Scutellum
small, densely covered with yellowish-white tomentum. Elytra at base two-
thirds wider than the base of the prothorax, two and one-half times as long,
three-fourths longer than wide, only slightly wider behind the middle than at
base ; humeri obtusely angalate, scarcely rounded, subprominent ; disk with-
out series but with moderately fine, deeply impressed punctures unevenly
distributed in longitudinal vittre, separated by subimpunctate narrower lines,
which have exceedingly remote larger punctures bearing the stiff erect setse.
Legs moderate in length, sparsely pubescent, the femora distinctly, acutely
toothed beneath. Length 5.5 mm. ; width 2.1^ mm.
New Mexico (Las Vegas). Mr. Meeske.
The uneven sculpture and sparse recumbent vestiture distinguish
this species from any other within our fauna ; it may perhaps be
allied to the Mexican Jlavipennis Chev.
6 O. egregillS n. sp. — Oblong-ovoidal, strongly convex, rather robust,
black and polished throughout, the upper surface clothed sparsely but con-
spicuously with short robust recurved white set?e, unevenly scattered on all
the interval of the elytra and mingled with longer finer erect and more widely
dispersed piceous setse ; legs and under surface rather sparsely but distinctly
clothed with short and more recumbent white hairs, dense and tufted on the
sternal side-pieces and mesosternum between the coxae, also with sparser
tufted hairs on the prosternum and toward the anterior margin of the meta-
sternum. Head coarsely but not very densely or deeply punctate ; eyes large
although not very prominent, separated by one-third of their own width ; beak
thick, just noticeably wider at apex, feebly bent, three-fourths as long as the
prothorax in the male, smooth and impunctate broadly along the middle, with
a feeble impressed line between the antennae, coarsely, closely punctate and
longitudinally sulcate laterally, hispid with erect setae ; antennae inserted at
apical third, long, slender, the first funicular joint a little longer than the next
two, club rather small, elongate, pointed, asymmetrically fusiform. Prothorax

distinctly longer than wide, the base and apex subeqnal in the male, the former
relatively narrower in the female ; sides feebly arcuate, convergent and straight
toward base ; punctures rather small, feeble, remote and unevenly distributed.
Scutellum densely pubescent. Elytra oblong, at base almost twice as wide as
the prothorax, nearly two and one-half times longer, three-fifths longer than
wide, not distinctly wider behind the middle than at base, the sides subparallel ;
strife broadly, rather strongly impressed, coarsely, deeply and not very closely
punctate; intervals convex, minutely, si:)arsely and unevenly punctate. Legs
rather short and stout, the femora strongly toothed ; tibiae bent toward base.
Lengtli 5.0 mm. ; width 1.9 mm.
Arizona.
The two specimens before me represent one of the most distinct
species of the genus, recognizable at once b}' the numerous coarse
recurved white set» of the upper surface, the subparallel elytra,
relatively narrow prothorax, large eyes and large femoral teeth. It
does not appear to be at all closely allied to any of the Mexican
species.

rather slender, not quite as long as the prothorax, confusedly, lon-
gitudinally sulcate and rugose, with an elongate feeble impression
in the middle between the antennae, the latter long, the second

the club long and evenly obcouical, with the sides straight. Pro-
thorax but slightly longer than wide, the sides sinuate behind the
apex and more broadly before the base, the apex broadly arcuate

series of coarse, rather close-set punctures. Legs slender, the femora
very long, the tooth small. Length 4.2 mm. ; width L6 mm.
Pennsylvania to Texas. A well-marked species which cannot
fail of recognition by reason of the sparse dual vestiture, coarse
sculpture and long slender feebly toothed femora. It does not
ap}tear to be abundant.

more than one-third of their own width ; beak in the male short, thick,
straight, two-thirds as long as the prothorax, smooth and impunctate above,

less rolnist form, more abundant and conspicuous white seta^ of the
elytra distributed along all of the intervals, and in the coarser

straight. Length 3.7-5.0 mm.; width 1.4-2.0 mm.
Rhode Island, District of Columbia, North Carolina and Indiana;
numerous specimens. This is a distinct species, easily known by
its strongly, posteriorly inflated elytra, feebly developed dorsal setae,
slender, straight, finely toothed femora and deep frontal fovea. I
do not know the law or pi'ecedent under which the name given by
Chevrolat was changed by Dr. Horn ; If myrmecodes Say is a
synonym of myrmex Hbst., as seems to be undoubtedly the case,
Chevrolat's name cannot be preoccupied.
12 O. rilficorilis n. sp. — Rather stout, convex, very feebly subcuneate,
black throughout and highly polished ; antennae and tarsi brownish-rufous ;
upper surface with numerous but very sparse, long, erect, blackish seta3, be-

where they are much shorter and subrecumbent ; scutellum and sternal para-
pleurae densely albido-pubescent. Head and beak rather sparsely but evi-
deJitly and unevenly punctate ; eyes separated by slightly less than their own

only just visibly bent toward base. Length 4.7-5.0 mm. ; width 1.7-1.8 mm.
Arizona.
Allied closely to myrmex, but larger and stouter, with the elytral
series finer and less impressed. I should have referred the two
specimens in my cabinet to mexicanus Chev., as they agree toler-
ably well with the description of Rosenskoeld, but the elytra, are
evidently much shorter, their length being given as almost three
times that of the prothorax in that species, while in ruficornis they
are only twice as long.

slender, the funicular joints two to four subequal, each slightly
elongate ; eyes moderate, separated by a little less than their own
width. Prothorax strongl}^ convex before the middle, sparsely,
rather strongly and unevenly punctate, one-fifth longer than wide,
the apex broadly arcuate and but slightly wider than the base.
Scutellum densely pubescent. Elytra very nearly twice as long as
wide, rather distinctly wider behind; punctures coarse, the series

feebly impressed. Legs rather slender; femoral teeth large ; til)ia3
bent toward base. Length 3.6-4.4 mm.; width L2-L6 mm.
This is a common species, easily recognizable by its narrow form,
the long blackish and somewiiat abundant seta3 of the upper surface,
and the strong strial punctures. My specimens are from New
Jersey, Pennsylvania and Indiana.

Rather narrowly and feebly cuneate, less convex above than usual,
polished and ferruginous throughout, the elytra piceous black in
apical half to two-thirds ; erect setae completely wanting, the body
throughout with extremely sparse recumbent squamules, very slen-
der in form and white in color ; scutellum densely tomentose ; sternal
side-pieces not densely pubescent, the met-episternum with a nar-
row uneven line of squamules. Head finely, sparsely but distinctly

rately large, strongly convex, coarsel\^ faceted, separated by fully
one-half of their own width ; beak very short, thick, cylindrical,
feebly sculptured even toward the sides; antenna? nearly normal,
but with the club very indistinctly annulated, the scrobes passing
beneath at a great distance from the eyes. Prothorax distinctly
elongate, subcylindrical, feebly and gradually inflated to slightly
l)ehind the middle, sparsely, distinctly but unevenly punctate.
Elytra behind the middle twice as wide as the prothorax and much

Georgia and Florida. The large series in my cabinet seems to
indicate Init little variability, except in the extent of the l)lackish
area of the elytra. This remarkal)le s})ecies is aberrant in its vesti-
ture and in the structure of the tarsal claws.
15 O. cavirostris n. sp. — Narrowly subcuneate, liiglily polished, strongly
convex, black, the legs, beak and antenna piceo-rufous ; body almost completely

tinctly punctate toward base and between the eyes, elsewhere entirely impunc-
tate ; eyes rather large, moderately prominent, separated by a little less than
their own width ; beak very short and robust, barely more than one-half as

tremely deep excavation just behind the middle, occupying the entire width,
rounded and bounded by an acute densely ciliate edge on the sides and behind,
the anterior edge obtuse and transverse ; bottom of the cavity ascending an-
teriorly and feebly bicarinate ; rostral surface between the cavity and apex
and also at the sides throughout, strongly though not very densely punctate ;
antennae short, the basal joint of the funicle robust, second slightly elongate,
third not quite as long as wide, outer joints thicker, club nearly as long as
the preceding six joints, strongly annulated. Prothorax distinctly longer than

0.6 mm.
Florida.
The single specimen of this extremely interesting species was
taken in the southern part of the State by Mr. F. Kinzel, and very
kindly presented to me by Mr. Wilhelm Jiilich. It is related to the
Cuban poe/yz Chev. in the extraordinary rostral excavation and un-
armed femora, but differs in coloration and, probably also, in its
smaller size and more sparsely punctate head. It is by far the most
minute of our species, and, together with poeyi, might well be
separated as a distinct genus.
OOPTERINIJS u. gen.
This genus is founded upon a remarkable species described by
Dr. Horn under the name Otidocephalus perforatum. It differs
from Otidocephalus in having the elytra ovate, rounded on the
sides, widest a little before the middle, gradually attenuate and
Coleopferological Notices, IV. 439
acutely rounded behind, and with the humeri entirely obsolete, in
the complete absence of scutellum, and in its small eyes. The
elytra are probably subconnate. In its short deeply sinuate pro-
sternum, short beak, and toothed claws, Oopterinus resembles
Otidocephalus.
O. perforatum Horn. — Proc. Am. Phil. Soc, XIII, p. 451.
Oval, piceous, the elytra and legs still paler, the upper surface
with a few rather short, semi-ei'ect, widely scattered whitish setsB.
Head sparsely but strongly punctate, the interocular surface impunc-
tate but with a small rounded median fovge ; eyes remarkably small,
coarsely granulated, separated by fully their own width ; beak rather
thick, feebly arcuate, almost as long as the prothorax, strongly
punctured at the sides and with a short longitudinally impressed
line between the antennae, the latter slender, the second funicular
joint obconical, one-half longer than the third ; club oval, rather
sparsely pubescent. Prothorax longer than wide, strongly narrowed
and feebly constricted toward base, very coarsely, deeply, slightly
unevenly but rather closely punctate. Elytra ovate, two-thirds
longer than wide, widest before the middle, the sides evenly rounded ;
humeri obsolete ; punctures very fine, dispo.sed in even series which
are entirely unimpressed except near the base. Legs very slender,
the femora broadly emarginate near the apex but not toothed.

The single specimen in the LeConte cabinet has no indication of
locality, but the original type, in the cabinet of Mr. Ulke, is from
Maryland.

Texas (Austin).
This is an interesting species, allied to naso, but having- the
antennae of the male still more apical in insertion, and the pronotal
sculpture nearly as m fiHSuriguis. A single specimen.
C integer n. sp. — Oblong-oval, moderately convex above, dull, black, the
elytra and legs with a feeble piceous tinge; ijubescence of the elytra not very
dense, consisting of sliort recumbent liairs, ochreous or fulvous in color, nearly
evenly distributed and scarcely at all mottled, mixed with short sparse set;ie,
not paler or denser behind the middle, the pronotum sparsely setose. Head
densely and rather finely punctate, the yellowish pubescence not extending
beyond the front ; beak long, slender, arcuate, about one-half as long as the
elytra in the male, strongly sulcate, the antennas inserted beyond apical third.
Prothorax very nearly as long as wide, the sides broadly rounded anteriorly,
becoming parallel and nearly straight in basal three-fifths, finely, moderately
constricted just behind the apex, the latter not more than one-half as wide
as the base ; disk coarsely, extremely densely, unevenly and subconfluently
punctate, evenly convex and with a fine entire median carina. Elytra one-half
wider than the prothorax and not quite three times as long, two-fifths longer

exposed but rounded ; disk with series of moderately large deep close-set
punctures, the alternate intervals with fine strongly-marked entire carinae.
Abdomen coarsely, very deeply and densely punctate. Legs long ; femora
moderately robust, subfusiform, obtusely and very feebly uni-dentate, the
toothed appearance caused principally by the abrupt and deep subapical
emargination ; tarsal claws divergent, strongly toothed. Length 6.0 mm. ;
width 2.9 mm.
Arizona (Tucson).
The single male represents a species allied to vaso, but with the
pubescence of the elytra much sparser and not at all condensed or
whiter behind the middle, and the pronotal sculpture more than
twice as coarse, being fully as coarse as in geminatus. Both this
species and carinifer have the peculiar oblong-oval form and general
rostral structure of naso, and should evidently be associated with it.
C. tlliplex n. sp. — Robust, suboval, strongly convex, blackish-piceous,
the elytra rufous ; vestiture of the anterior parts very sparse, in the form of
long stifi" anteriorly directed setis, on the elytra of moderately dense, somewhat
uneven prostrate hairs, coarser denser and paler yellowish toward the humeri
and transversely behind the middle, also with long stiff' erect setse. Head
densely punctate and with sparse subrecumbent yellow hairs, the front with
a deep median fovea ; eyes moderate, remotely separated ; beak moderately
thick, feebly, evenly arcuate, fully as long as the head and prothorax, very
deeply, longitudinally punctato-sulcate, strongly carinate along the middle ;
antennae inserted at apical third, the second funicular joint very long, about

as long as the first and twice as long as the third. Prothorax very nearly as
long as wide, the sides subparallel and just visibly arcuate in basal two-thirds,
then convergent and rather strongly constricted, the apex somewhat strongly
arcuate, three-fouFths as wide as the base ; disk very coarsely, deeply punc-
tate, the punctures even but closely crowded and polygonal, without trace of
any kind of median line. Elytra three-fifths wider than tlie prothorax, two
and two-fifths times longer, only slightly longer than wide, the sides becoming
straight and nearly parallel in basal half; liumeri riglit, narrowly rounded,
broadly exposed at base ; disk with series of rather coarse punctures ; inter-
vals three, five, seven, eight and nine more or less strongly and uninter-
ruptedly carinate. Abdomen coarsely deeply and densely punctate. Legs not
very robust, the femora with a single fine tooth ; claws feebly divergent acutely
toothed internally near the base. Length 4.3 mm. ; width 2.3 mm.
California. Mr. Harford.
Somewhat resembles fissunguis in form, but differs in the alter-
nately broadly carinate elytral intervals and the long bristling erect
seta3, as well as in the structure of the claws. The precise locality
is unknown, but is in all probability southern, as Conotrachelus does
not appear to enter the true Pacific coast fauna.
C. rotundUS n. sp. — Robust, oval, convex, black, the legs rufescent ;
vestiture of the pronotum sparse, of the elytra rather dense and consisting of
very short robust subrecumbent squamules, smaller even and ochreous on the
alternate intervals, whiter broader and submaculate on the others, the upper
surface throughout with stout erect clavate bristles, rather sparsely but evenly
distributed and moderate in length. Head finely, very densely punctate ; eyes
remote ; front and basal parts of the beak densely squamulose ; beak rather
thick, evenly arcuate, fully as long as the head and prothorax, deeply, longi-
tudinally sulcate ; antennae inserted near apical third, rather stout, the second
funicular joint scarcely as long as the first. Prothorax small, two-fifths wider
than long, the sides feebly convergent from the base and rather strongly
arcuate, more strongly convergent near the apex but not distinctly con-
stricted ; apex broadly arcuate and about three-fourtlis as wide as the base ;
disk with extremely coarse uneven and densely crowded fovese, tlie surface
rough but evenly convex and without median line. Elytra abruptly four-
fifths wider than tlie prothorax, not quite three times as long, not longer than
wide, the sides parallel and nearly straight to the middle, then convergent
and rounded feebly sinuate before the apex ; disk with broadly, deeply im-
pressed series of moderately large deep punctures, the intervals nearly equal
throughout and broadly, evenly convex, not in the least carinate at any point.
Abdomen rather coarsely, densely punctate. Legs not very stout, the femora
eacli with a single rather small but distinct tooth ; tarsal claws rather diver-
gent, bent downward near the base and with a long straight internal tooth
near the base, widely diverging from the claw and almost eqitalling it in
length. Length 3.0 mm. ; width 1.9 mm.
CoIeo2:>te7'oIogical Notices, IV. 443
Texas (near Austin).
A distinct species, easily distinguishable by its rather small size,
obese form and peculiar thick clavate bristles. Tog-ether with
diqjlex, it should be placed at the end of LeConte's group "I b,"
but there are no described species with Avhich either of them can be
compared.
The genera allied to Ryssematus, which have thus far occurred
within the United States, may be readily distinguished as follows: —
Intermediate coxre narrowly separated ; second ventral segment not as long
as the next two combined.
Tarsal claws unequally cleft, approximate but not connate at base.
Ryssematus
Tarsal claws simple, stout, subparallel, subconnate at base, the suture dis-
tinct Clialcoderniiis
Intermediate coxse widely seijarated, the mesosternum between them depressed
and flat ; second ventral segment longer than the next two ; tarsal claws
small, slender, approximate at base but free Clialepoiiotus
RYSSEMATUS Chey.
B. pruinosus Sch. is somewhat aberrant in its more elongate-oval
form and in the longer flatter abdominal segments, also in its very
slender beak, joined at the lower part of the head at an obtuse angle.
R. ovalis n. sp. — Evenly oval, strongly convex, shining, glabrous, dark
rufo-testaceous throughout. Head strongly convex, finely, densely punctate,
with a small interocular fovea ; eyes moderate, unusually distant, separated
by rather less than their own width above ; beak rather slender, evenly,
moderately arcuate, shining, finely, sparsely lineato-punctate, a little longer
than the head and prothorax ; antenna inserted just behind the middle, the
scrobes horizontal, nearly attaining the lower portion of the eye ; funicle long,
slender, all the joints longer than wide, the first almost as long as the next
three, second but slightly longer than the third, the club moderate, scarcely
longer than the three preceding joints, oval, abrupt. Prothorax not quite twice
as wide as long, the apex strongly constricted and tubulate, less than one-half
as wide as the base ; sides evenly convergent and arcuate from the base, the
latter transverse, broadly, feebly bisinuate and with the usual narrow decliv-
ous margin ; disk finely, deeply strigilato-punctate, the strigae externally
oblique anteriorly, the median line very fine and not distinctly cariniform.
Elytra slightly wider than the prothorax and nearly three times as long,
oval, the sides becoming parallel near the base, the humeri obliquely, feebly
rounded externally to the prothorax and not exposed at base; disk with

intervals equally convex, becoming somewhat acute toward apex, finely and
unevenly punctate along the sides of the grooves. Abdomen finely, rather
sparsely punctate. Legs short, the femora very robust, the denticle strong ;
tibiae stout, bent toward base, enlarged toward, and externally prominent at,
the apex. Length 3.8 mm. ; width 2.0 mm.
Texas.
A rather small, evenly convex and isolated species, having the
eyes much more widely separated than in any other form which I
have seen. The structural characters are, however, all of this
genus. The ocular lobes are moderately well developed as usual in
this group.
Chalcodermus includes but three species within our faunal limits,
— seneus, insequicoUis, and collaris. The species identified by
LeConte as spinifer Boh., belongs to a widely different tribe of
Curculionidffi.
CHAI.EPO]¥OTUS n. gen.
This genus is allied to Chalcodermus, but differs in the following
characters : —
Antennal scrobes feebly descending to the lower angle of the eyes, the basal
joint of the funicle not as long as the second. Second abdominal segment
much longer than the next two combined, the suture broadly, evenly angu-
late throughout its width. Middle coxse widely separated. Tarsal claws
small, slender, approximate at base but not at all connate.
It also differs in many other features, the body, for example, being
more finely sculptured, aud the elytral intervals elevated as in many
species of Ryssematus. The mandibles are very thick, strongly,
evenly arcuate in external outline, the apex prolonged and acute.
C elllSllS n. sp. — Oval, convex, shining, black, glabrous; each puncture
bearing a vnry minute seta. Head finely, not very densely punctate ; eyes
rather distant, separated by nearly their own width on the front ; beak rather
slender, cylindrical, evenly, feebly arcuate, as long as the head and prothorax,
finely, sparsely punctate, shining, the antenn?e inserted a little beyond the
middle, the second funicular joint elongate, fully as long as the next two,
outer joints thicker, the seventh scarcely as long as wide, club scarcely longer
than the three preceding joints, oval, pointed, not very abrupt. Prothorax
scarcely more than one-fourth wider than long, subconical, the sides evenly
convergent and broadly arcuate from the base to the distinct but not strong
subapical constriction, the apex arcuate, a little more than one-half as wide
as the base ; disk finely, deeply and evenly punctate, the punctures separated

by nearly their own widths, with a narrow impunctate spot at tlie middle.
Scutellum small, tumid. Elytra one-third wider than the prothorax, two and
one-half times as long, ogival, the sides becoming scarcely parallel at base,
the humeri oblique to the base of the prothorax ; disk with fine impressed
stripe, having moderately small deep elongate and remote punctures, wider
than the strise, the intervals equal, strongly, angularly convex, with a feeble
series of small punctures at each side of the summit. Abdomen finely, sparsely
punctate. Legs moderate ; femora not very stout, the denticle strong, inclined ;
tibi?e rather slender. Length 4.0 mm. ; width 2.0 mm.
Indiana.
Easily distinguishable by the fine even separated punctures of the
prothorax, the latter being unusually elongate. A single specimen.
ACAMPTIJS Lee.
This is a conspicuously distinct and aberrant genus with the met-
epimera invisible, the episterna distinct, the anterior coxa? large,
prominent, contiguous but excavated internally to receive the very
short thick beak, the eyes concealed in repose, antenual club solid,
and third and fourth abdominal segments short. The tibi;\.' termi-
nate in an unusually large internal spur and the tarsi are slender
and cylindrical, with the third joint undilated ; the claws are slen-
der, free and divergent. The bod}^ is narrow and elongate, brist-
ling with thick erect clavate seta?. The two species may be thus
distinguished: —
Elytra shorter, scarcely more than one-half longer than wide and not twice as
long as the prothorax, the latter broadly and feebly constricted behind
the apex ; dorsal bristles short and sparse throughout, the elytral ridges
moderate rigid IIS Lee.
Elytra much longer, fully three-fourths longer than wide and more than twice
as long as the prothorax, the latter broadly and deeply constricted behind
the apex ; dorsal bristles twice as long and very close-set, extremely
robust and squamiform ; elytral ridges strong. Body elongate, parallel,
subcylindrical. Head and beak densely squamose, the latter bristling
with erect scales especially toward base, not more than two-thirds as long
as the prothorax, the antennse inserted near the middle, the funicle gla-
brous, the basal joint aboiit as long as the next two, outer joints gradu-
ally thicker, coarctate, club rather small. Prothorax fully as long as wide,
the apex broadly arcuate and slightly narrower than the base, coarsely,
indistinctly punctate. Scutellum small, distinct. Elytra one-third wider
than the prothorax, the sides straight and nearly parallel in basal three-
fourths, each with four ridges bearing long erect close-set scales, the in-
tervals alutaceous, biseriately punctate. Length 4.3 mm. ; width 1.6.5

446 Coleopterological Notices, IV.
The vestiture is pale yellowish in color throughout, the integu-
ments in echinus being dark red-brown. In both of the species the
prothorax is very obliquely truncate at the sides, so that the head
and beak are invisible from above ; the ocular lobes are small. The
antennal funicle is 7-jointed and not 6-jointed as indicated in the
original description.
MICROMASTCJS Lee.
The principal sternal characters of this genus appear to have been
in great part misconceived by the author. The beak is moderately
thick and perfectly free, the prosternum broadly, feebly impressed,
the impression punctate, setose and much wider than the beak, the
anterior coxae large, conoidal, prominent and subcontiguous. The
intermediate coxa3 are somewhat Avidely separated, the mesosternum
between them transversely tumid, densely punctate and setose. The
metasternum is only moderately short and is longer than in Acalles ;
epimera and episterna both invisible, the third and fourth abdomi-
nal segments short. Micromastus is an isolated genus intermediate
between Conotrachelus and Acalles.
ACALLES Schoiih.
The following is a large species belonging in the neighborhood of
nohilis : —
A. profusiIS n. sp. — Oval, convex, black rather sparsely clothed with
large recumbeut scales, without erect setse, the scales dark brown in color but
in great part white and denser on the head and basal parts of the beak, in
several small isolated spots on the prothorax, on the elytra especially near the
sides in basal fourth and in a transverse band near apical fourth, on the
femora toward apex and throughout the tibife. //eacZand beak rather coarsely,
densely punctate, the latter finely carinate along the middle, rather longer than
the prothorax ; antennae inserted at the middle. Prothorax very nearly as long
as wide, the sides broadly arcuate, somewhat more convergent toward apex,
the subapical constriction fine ; apex broadly arcuate and a little more than
three-fourths as wide as the base ; disk coarsely, very densely punctate, the
median impunctate carina strong but not entire. Elytra oval, more than twice
as long as the prothorax, and, in the middle, nearly one- half wider ; foveas
very large, deep and close-set, each with a rather small subquadrate scale.
Abdovien coarsely, rather closely punctate. Length 7.5 mm. ; width 3.7 mm.

Differs from porosus and basalis in its larger size and strongly

carinate pronotum, and from nobilis in its less inflated elytra and
the dense white scales covering the basal third of the beak.
CAWISTES n. gen.
This genus is founded upon a remarkable species somewhat re-
sembling an unusually robust Calandrinus. It is however allied to
Acalles, as may be seen from the following diagnosis : —
Body oblong-oval, strongly convex. Beak moderate in length received in
a very deep and abruptly limited sternal sulcus, extending almost to the
metasternum. Eyes not very large, almost completely concealed in repose,
the ocular lobes moderate. Antenn?e inserted just behind the middle of the
beak, the funicle 7-jointed, slender, the basal joint not quite as long as the
second, the latter nearly as long as the next three combined ; outer joints but
slightly thicker ; club abrupt, rather large, elongated, cylindric-oval, fully as
long as the preceding five joints, very densely pubescent, solid but with a
distinct apical segment. Metasternum very short, the episterna distinct,
parallel, the epimera not visible. Abdomen with the first suture distinct,
broadly, strongly arcuate, the second segment much longer than the next two
together. Legs thick and robust ; femora unarmed ; tibi?e aberrant, the inter-
mediate and posterior gradually and rapidly increasing in width to the middle,
then abruptly narrowed, the apical half parallel and not wider than tlxe base,
the inner side straight throughout ; tarsi short, slender, the third joint dilated
and bilobed ; claws small, simple, very slender, free and divergent. Seutel-
lum completely obsolete.
Canistes differs greatly from Acalles in abdominal structure, but
resembles A. nuchalis not only in this feature, but in the broadly
visible met-episterna. The new genus which must be formed for
A. nuchalis will however differ from Canistes in its distinctly annu-
lated antennal club and normal tibise. In general facies Canistes
departs widely from any other type of North American crypto-
rhynchs.
C. SCllUSteri n. sp. — Subparallel, black, the antennae rufous with the
club still paler and subsericeous ; body sparsely and very unevenly squamose,
the head extremely densely clothed with small fulvous recumbent scales, the
pronotum with some similar but more elongate scales toward the sides and
also bristling with short erect and sparse setae, especially toward apex, the
elytra smooth, alutaceous almost glabrous, with a few widely scattered scales
of various shapes, some recumbent, others erect, especially visible toward base,
in a transverse line at apical third, and thence narrowly along the suture to
the apex, the abdomen with a few elongate and widely dispersed scales ; legs
densely and conspicuously clothed throughout with small recumbent brown
scales, erect and bristling externally along the tibiae. Head densely punc-

tate ; beak feebly arcuate, not quite as long as the prothorax, smooth, shining
and finely, sparsely punctate except in less than basal half, where it is punc-
tate and squamose. Prothorax slightly wider than long, wider at the middle
than at base, the sides in basal half nearly straight, strongly convergent and
deeply sinuate anteriorly, the constriction very large, deep, extending entirely
across the dorsal surface ; disk coarsely perforato-cribrate, the punctures sepa-
rated by much less than their own diameters, the interspaces flat and polished,
without modified median line. Elytra scarcely wider than the prothorax, two-
thirds longer, narrowed and broadly constricted behind, the apex narrowly
obtuse ; disk with very fine sparse punctures, not striate, the punctures how-
ever becoming coarse and seriate very near the base. Abdomen finely, sparsely
punctate, smooth and polished toward base. Length 3.3 mm. ; width 1.(3 mm.
JNIissouri (St. Louis).
The single specimen was discovered by Mr. Moritz Schuster of
St. Louis, to whom it gives me pleasure to dedicate a most interest-
ing addition to our Cryptorhynchiui.
TYLODERMA Say.
This genus is widely differentiated from Cryptorhvnchus l)y the
short thick beak, consequently received in a much more shallow
emargination of the tumid mesosternum, by the small eyes, almost
completely concealed in repose by the ocular lobes, and by the six-
jointed antennal funicle ; in addition, it should be stated that the
femora are unarmed and are only moderately stout. The third
tarsal joint is dilated and bilobed, and the tarsal claws are small
slender free and simple. The species usually vary greatly in the
size of the body and in intensity and coarseness of sculpture, espe-
cially that of the elytra.
In a perfectly natural succession of the North American forms
we can readily recognize four typical groups, represented respec-
tively hy foveolata,^ fragaiHse, variegata and eerea, the species in
each group being rather closely allied among themselves. The
1 It is desirable to make the rules of nomenclature as uniform as possible,
and independent of linguistic exceptions. This can be accomplished in one
direction by adopting a constant gender for each particular ending of the
generic symbol, taking as a guide the general Latin rule in each case. In this
instance, it is the general rule that words ending in " a" are feminine, conse-
quently all generic symbols ending in "a," of whatever derivation, should
require a feminine termination in the specific word. It would be a decided
advance if a table of genders could be drawn up and agreed to, for every pos-
sible ending of the generic symbol.

second of those mentioned is monotypic and is perhaps the most
aberrant in general form and habitus. The species occur through-
out the United States, and are also well represented in Brazil ; those
which I have been able to study may be characterized as follows: —
Body more or less dull, very coarsely, deeply sculptured, the protliorax with
large uneven fove?e.
Elytra with a squamulose spot at each side of the scutellura.
Elytral series hecoming subobsolete and feebly punctate near the apex.
Pronotal fovese much larger than the scutellura ; vestiture composed of
brownish-white squamules 1 foveolata
Pronotal fovese sensibly smaller and more distant, not much larger than
the scutellura at any point ; squaraules broader in forra and white.
2 mor1)iIlosa
Elytral series distinct throughout, the punctures of the two series nearest
the suture on each deep and large to the apex ; body much narrower
and more cylindrical, the jirothorax from above not constricted at the
sides toward apex 3 angtistllla
Elytra without trace of a squamulose spot near the scutellura ; elytral series
broadly, deeply impressed to the apex ; prothorax not sensibly sinuate at
the sides anteriorly ; humeri much less broadly exposed, not at all trun-
cate at base but broadly rounded to the base of the prothorax.
4 contiisa
Body smoother and more shining, glabrous or very sparsely and unevenly
pubescent, less distinctly polished in fragarice, the pronotum punctate
rather than foveate.
Elytra oval, widest near basal third ; pronotum very coarsely deeply and
densely punctate ; integuments in great part rufo-2)iceous...5 fragariae
Elytra becoming parallel and straight at the sides toward base.
Integuments more or less pale ; pronotal punctures coarse uneven and
impressed.
Prothorax rather longer than wide, densely and confusedly punctured
toward apex ; elytra black, sparsely mottled with rufous.
6 variegata
Prothorax not as long as wide, much more broadly inflated toward base,
remotely and unevenly punctate throughout ; elytra rufous, occa-
sionally very distantly and just perceptibly mottled with blackish :
beak shorter 7 rilfesceilS
Integuments black or piceous-black, often aeneous, rather shining ; pro-
notum more or less minutely punctate.
Elytral humeri very narrowly exposed at base 8 1)ai'iilia
Elytral humeri broadly exposed.
Upper surface with very sparse whitish recumbent hairs.
9 sulbpubescens
Upper surface glabrous.
Punctures of the pronotum strong tliough sparse throughout ; body
rather robust 10 nigra
450 Goleopterological Notices, IV.
Punctures of the prouotal disk very fine or subobsolete ; body nar-
rower.
Punctures of the pronotal tlanks strong and unevenly distributed
over the entire surface 11 aerea
Punctures of the flanks entirely obsolete, except in the sul^apieal
constriction 12 punctata
T. longa Lee. (Proc. Am. Phil. Soc, XV, p. 248) belongs to
Cryptorhyuehus as at present organized, and has the eyes large
and approximate, as usual in that genus. I have before me one
or two species from Brazil, which are similarly elongate-cylindrical
in form and otherwise closely allied to longa. In these forms the
antennal funicle is short and T-jointed, the outer joints very short,
gradually slightly thicker and coarctate ; they should perhai>s form
a distinct genus.

468 (Analcis).
Oblong-oval, strongly convex, black and dull throughout, gla-
brous but with small patches of small slender dense recumbent and
whitish scales, of which a small spot at the middle of the vertex
and another larger and more elongate between the eyes, a short line
at the apex of the pronotum and an obliquely arcuate series from
before the middle to near the sides of the base, numerous irregular
.spots on the elytra and a broad uneven band at apical fourth, are
especially noticeable. Head and beak not very coarsely but rather
closely and distinctly punctate, with a feeble frontal puncture. Pro-
thorax scarcely as long as wide, strongly rounded at the sides, the
latter convergent and broadly sinuate toward the broadly arcuate
apex ; disk with extremely coarse, deep, uneven but rather close-set
fovea?. Elytra between one-third and one-fourth wider than the
disk of the prothorax, the sides subparallel and nearly straight in
basal two-thirds, the humeri right but narrowly and obliquely sub-
truncate; disk with unimpressed series of extremely large deep
uneven fovea?, which become almost obliterated toward apex.
Length 3.7-5.8 mm. ; width L5-2.7 mm.
The large series before me is from New Jerse}^, Pennsylvania and
Iowa ; it is also said to occur in Georgia. In well preserved speci-
mens each of the large fovetB of the pronotum bears a short stiff
subclavate seta. The only remarkable variation is in the size of
the body.

Closely allied to foveolcUa, but a little less robust, the elytra more
elongate and with the small spots and posterior interrupted band
composed of squamules which arc whiter and slightly broader, the
scales of the small spots on the head and flanks of the prothorax
still broader. The prothorax is shorter, with the apex relatively
wider, broadly arcuate, the sides in basal three-fifths nearly parallel
and much less arcuate, thence feebly convergent and just visiljly
sinuate to the apex ; fovea? smaller, rather sparser and very unevenly
distributed. Elytra one-fourth wider than the prothorax and rather
more than twice as long, the sides parallel and nearly straight in
basal two-thirds, the apex narrowly parabolic; humeri right, slightly
blunt; foveae very large, uneven in outline, forming vague series
and almost contiguous toward base, the series fine, slightly im-
pressed and very feebly punctate toward apex, the two lateral more
distinctly punctate and feebly carinate externally in apical half.
Length 5.0 mm. ; width 2.0 mm.
California (San Francisco). The unique type in the LeConte
cabinet is the only specimen which I have seen. This species may
possibly prove to be a geographical variatioif of foveolata, but it is
impossible to pronounce any definite opinion until more specimens
are discovered.
3 T. angustllla n. sp. — Subelongate, strongly convex, black, the legs
dark piceo-rufous ; integuments dull, the elytra more shining, subglabrous
but with a small condensed spot of recumbent squamules on tlie front, a few
scattered squamules near the centre of the occiput, some very sparse indefinite
spots on the prothorax and anterior parts of the elytra especially near the
scutellum, an oblique spot near apical fourth and aiaother between this and
the apex of each elytron, the squamules whitish in color. Head and beak
very unevenly but distinctly punctate, the former more sparsely and with an
indistinct frontal fovea ; beak very short, barely one-half longer than wide ;
antenuEe rufous, the basal joint of the funicle very robust, not quite as long
as the second which is slender and obconical ; club densely clothed with short
coarse pearly pubescence. Prothorax not quite as long as wide, the sides
broadly, distinctly arcuate in basal three-fifths, becoming more convergent
near the base, strongly convergent and nearly straight in apical two-fifths,
the apex strongly arcuate and much narrower than the base ; disk with ex-
tremely large deep uneven and partially confluent fovea, without smooth
median line. Elytra elongate, one-fifth wider than the prothorax and almost
two and one-half times as long, subjiarallel, the apical portion ogival, with
the extreme apex subtruncate ; humeri broadly exposed, obliquely subtrun-

series impressed toward apex, especially the two nearest the suture, in which
the punctures are but slightly smaller at the apex ; punctures of the lateral
series becoming very small at about posterior third but again larger toward the
apex ; intervals between the series each with an even series of very small re-
mote punctures. Length 3.7 mm. ; width 1.3 mm.
Texas (Austin).
The single specimen, which I took at the indicated localit}^, re-
presents an interesting species somewhat allied to foveolata, but
much narrower and differently sculptured toward the apex of the
elytra.
4 T. contlisa n. sp. — Rather narrowly oblong-oval, strongly convex,
black throughout, the upper surface rather shining but with a distinct alu-
taceous lustre, almost glabrous, the squamules slender, recumbent, aggregated
in two small spots on the head, one in the middle near the apex and two
arranged transversely on the flanks of the pronotum, one or two very feeble
spots on the disk of each elytron near basal third and in the usual transverse
interrupted band at apical fourth, the squamules pale brownish in color.
H(:ad and beak finely, sparsely punctate, each puncture with a small seta,
the front with a short longitudinal canaliculation connecting the two squamose

strongly convergent and st^'aight to the apex, and feebly convergent and nearly
straight to the base, the apex much narrower than the base and strongly arcu-
ate ; fovese of the surface extremely large, deep, uneven, a wide median line
smooth and very narrowly and feebly tumid. Elytra barely one-fourth wider
than the prothorax, twice as long, parallel and straight at the sides in basal
two-thirds, the apex parabolic ; humeri rounded to the base of the prothorax ;
disk toward base with extremely large uneven semi-confluent fovese, arranged
in series, becoming smaller and distant but distinct toward apex, the series
there being broadly deeply and conspicuously impressed. Length 3.3 mm. ;
width 1.3 mm.
Arkansas (Little Rock). Mr. H. F. Wickham.
A small species, allied rather closely io foveolata, but with a more
shining and subglabrous surface, much larger denser and more con-
spicuous elytral fovete, narrower bodily form, less widely exposed
humeri and non-sinuate sides of the prothorax toward apex. In
foveolata the elytral series are almost unimpressed near the apex.

clouded spot at the middle nearer the side than the suture, and an-
other smaller and rounded at apical fourth ; surface feebly shining,
the vestiture very sparse, consisting- of short robust recumbent
hairs, yellowish in color and especially evident on the elytra near
the base, in an oblique band just before the middle, and another at

the disk of the prothorax, three-fourths longer, widest at basal third
where they are two-fifths wider than the prothorax, minutely punc-

soletely impressed series of very distant punctures, becoming coarse
toward base and minute toward ai)ex. Length 4.0-4.2 mm. ; width
1.8-1.9 mm.
Illinois and Missouri. One of the most distinct species of our
fauna, perhaps most closely allied to variegata, but radically differ-
ent in its shorter oval and confusedly punctulate elytra, with the
humeri scarcely at all exposed at base, and in its very dense cribrate
l)unctures of the prothorax.

This species is allied rather closely to variegata, but is easily dis-
tinguished by its slightl}' stouter form, pale coloration, wider and
more inflated prothorax, much sparser punctuation throughout, the
punctures rather larger on the prothorax but smaller and more even
on the el3'^tra, and by the shorter beak in the female.

The single specimen represents a distinct species, somewhat inter-
mediate Ijetween the fragariae. and serea groups ; it very closely
resembles serea, but is relatively narrower and may be readily dis-
tinguished by the long sparse hairs of the elytra.

Elong-ate-oval, very strongly convex, polished, black with a strong-
bronzy lustre, glabrous. Head rather dull, finely, sparsely punc-
tate, with a small vertical fovea, the impression between the head
and beak deep but broadly rounded. Prothorax about as long' as
wide, the sides almost straight and evenly convergent from base
to apex, but arcuate for a short distance in the middle; apex fully
three-fourths as wide as the base, strongly arcuate ; disk almost
imi)unctate, the upper portion tow^ard base with excessively minute
and subobsolete sparse punctures; a transverse area just behind the
apex is also more distinctly and confusedly punctate, the punctures
becoming large and deep in a still narrower and more apical line
on the flanks; remainder of the sides without distinct punctures.
Elytra at base nearly one-third wider than the prothorax, two and
one-half times as long, gradually ogival behind, the sides becoming
subparallel in basal half; disk with unimpressed series of coarse,
deep, very remote punctures, not extending behind the middle.
Length 2.5-3.9 mm.; width 0.95-1.7 mm.
New York (Long Island) and Florida. A polished species re-
sembling ^rfia, but larger, relatively somew^hat narrower, with more
elongate and more gradually narrowed elytra ; it may always be
easily recognized by the peculiar punctuation of the prothorax. The
elytral punctures, as in serea, vary greatly in size and depth, and,
in one very small depauperate specimen from Florida, become nearly
obsolete.
PHYRDENUS Lee.
In this genus the anterior coxa? are only moderately separated,
the excavation in the mesosternum being much wider, surrounded
by a strongly elevated acute edge and not extending beyond the
middle of the intermediate coxae ; the beak is strongly compressed
toward base and dilated and flattened toward apex, as might be
inferred from the relationship of the anterior coxal distance and
wndth of the mesosternal sulcus. The two species in my cabinet
may be thus distinguished : —
Second abdominal segment nearly as long as the next two ; basal segment
abruptly much more coarsely and almost uniformly punctate ; median
sulcus of the pronotum equal in width throughout, deep but not very
wide, the pronotal sculpture coarse lindattis Lee.
458 Coleopterological Notices, IV.
Second abdominal segment but slightly longer than the third, the basal seg-
ment not more coarsely punctate but having in addition to the finer punc-
tures others much larger and widely scattered. Head and beak roughly
and densely squamose, the former strongly, transversely impressed ; beak
not quite as long as the prothorax, feebly bent, roughly and densely sculp-
tured ; antennae inserted just beyond apical third, the second funicular
joint but slightly shorter than the first, equal to the next two together,
outer joints but slightly wider, club long, distinctly annulated. Protho-
rax very nearly as long as wide, angulate at the sides before the middle,
the disk very uneven, the median impression broad and feeble ; piinctures
very dense but even and rather fine. Elytra about twice as wide as the
prothorax, not longer than wide ; intervals alternately strongly ridged
and flat; punctures coarse and rather uneven. Length 5.4 mm. ; width
3.0 mm. Arizona liullatlis n. sp.
Bullatus is larger and relatively broader than undatus. The
vestiture in the single specimen before me is somewhat imperfect,
but appears to be of the same general character as in undatus; the
latter is moderately abundant from Xew York to Texas.
Zygopini.
PSOJMIJS n. gen.
A distinct genus is rendered necessary for one of the most minute
zygopides which I have seen. Its principal characters are the fol-
lowing : —
Body small, oval, convex, somewhat resembling Orchestes. Eyes large,
finely faceted, narrowly separated on the front. Beak somewhat slender,
received in repose in a moderately deep prosternal sulcus, thence passing
over, but scarcely upon, the mesosternum. Antennae very slender, the funicle
long, filiform, the basal joint rather longer than the next two ; second longer
than the third ; outer joints but slightly thicker ; club very small, moderately
thick, oval, not noticeably annulate. ]VIe.sosternum depressed, flat, very widely
separating the coxae. Met-episterna rather narrow, parallel, interposed be-
tween the posterior coxae and the elytra. Abdomen nearly flat, the sutures
straight, transverse, all deep and strong, the segments subequal in length.
Pygidium completely covered. Legs moderate, the tibiae and tarsi very short ;
tarsal claws small, divergent, bent downward near the base and obtusely
toothed or lobed within.
The systematic position of Psomus is evidently near Acoptus,
with which it agrees in sternal structure ; the facies is how^ever
completely different, and structurally it differs in its very slender
antennte with small non-annulate club, short tarsi with the claws
Coleopterological Notices, IV. 459
somewhat appcncliculate and not simple, in its still more equal ven-
tral segments and relativel}^ larger eyes. The femora are broadly
sinuate beneath toward apex, but not in the least dentate.
P. politus n. sp. — Oval, strongly convex, highly polished, black, the
tip of beak, antennae, tibise and tarsi very pale luteo-Mavate ; femora black ;
body almost glabrous, the upper surface with a few remote inconspicuous
setiform squaraules, especially evident and somewhat bristling between the
eyes, on the prosternum and flanks of the prothorax. Head finely punctate ;
beak a little more than one-third as long as the body, smooth, shining, rather
coarsely but not densely, sublinearly punctate, the antennae inserted ratlier
behind basal third. Prothorax small, conical, three-fifths wider than long,
the sides almost straight, subapical constriction very feeble ; apex broadly
arcuate, about two-thirds as wide as the base ; disk finely but strongly, not
closely punctate. Scutellum small, tumid, albido-setose. Elijtra at base
abruptly two-fifths wider than the prothorax, between three and four times
as long ; sides rounded, convergent and feebly sinuate toward apex, becoming
parallel near the base ; humeri rather tumid, obtuse ; disk with very fine but
distinct striae, feebly, remotely crenato-punctate ; intervals wide, broadly con-
vex, each with a single series of extremely minute distant and feebly setiferous
punctures. Abdomen rather closely, subrugosely punctate. Length 1.5-1.8
mm. ; width 0.7-0.9 mm.
Indiana.
This is an interesting addition to the Zygopini of the United
States and constitutes a widely isolated generic type. Two speci-
mens.
ZYGOPS Schijnh.
I have before me two species of this genus which may be thus
characterized : —
Lateral vittae and median pale spots of the pronotum abruptly defined ; post-
medial whitish spots of the elytra arranged transversely ; upper portion
of the pygidium black, except narrowly near the edges and along the
subcarinate median line ; abdomen with a denuded spot near each side
of the fifth segment seiuilliveus Lee.
Lateral pronotal vittae rather well defined, the median spots not at all defined,
replaced by large indefinitely nubilate areas; post-medial spots of the
elytra oblique ; pygidium with mixed pale and dark scales ; fifth ventral
segment almost uniformly clothed throughout with white scales. Body
otherwise nearly resembling seminiceus, the beak more coarsely and.

Besides the characters mentioned, it should be added that the
eljtral pale spots in suffusus are composed of white and pale browu
scales, the larger white areas being- narrowly margined with the
brown tint, while in seminiveus all the scales are whitish.
Baiiixi.
This immense tribe forms an important subdivision of Lacor-
daire's second section of those apostasimerous phanerognathic Cur-
culionida?, which have the anlennal club articulate or divided by
distinct sutures, and the third tarsal joint bilobed. There are, how-
ever, several important exceptions to these characters even in the
tribe under consideration, and it may prove almost as natural to
consider the Barini as forming one of the tribes in the second of
two great primary divisions of the Curculionidte — as limited by
LeConte — based upon the form of the mesosternal epimera ; the
first having the epimera undeveloped laterally and the second
having this part produced and angulate upward or ascending at
the sides of the body, obliquely truncating the elytra at the humeri
and often visible from above. At all events the latter is the principal
structural character separating the Barini from other curculionides.
and is the most constant and significant feature of the tribe.'
Among the few tribes possessing this peculiarity, the Barini may
be known at once by the distinct scutellum, generally free beak with
obliquely descending or inferior antennal scrobes and by the un-
emarginate prosternum, but it must be admitted that there seems
to be quite as strong a bond of affinity between the Barini and
Cryptorhynchini, as between the former and the Ceutorhynchini,
with which they are to be associated by reason of mes-epimeral struc-
ture. Lacordaire distinguishes the Barini from the Ceutorhynchini
principally by the presence of a distinct scutellum in the former ;
so, as in many other large and complicated divisions of the Coleop-
tera, we are forced to rely for tribal characters mainly upon habitus,
supported by one or two tolerably constant special peculiarities. As
thus defined by the conformation of the rnes-epimera, the Barini
include an extremely large proportion of all the special modifications
of structure found elsewhere in the Curculionidfe.
1 In the Zjgopini it sometimes occurs it is true, but here it is always sporadic
and of but little if any systematic value.
Coleopterological Notices, IV. 461
The beak may be excessively short and stout or correspondingly
long- and slender, arcuate or nearly straight or variously bent at
different parts of its extent, divided from the head by a transverse
constriction or not, and with the antenna; inserted at every con-
ceivable point, from near the extreme apex as in the male of Cono-
proctus 4:-pustulatus, to near the base as in Simocopis of Pascoe or
our own Plocamus. The scrobes obliquely and rapidly descending
or nearly horizontal, sometimes completely inferior, coalescent be-
neath toward base or remaining widely separated.
The antennifi are comparatively constant in structure, especially
the funicle, which is invariably seven-jointed, with the basal joint,
and moi'e rarely also the second, elongate to a greater or less degree,
the first sometimes as long as the entire remainder as in Barinus;
the second joint is, however, almost always at least somewhat longer
than the third. The club is modified to a very noticeable extent,
but it is seldom that these variations of structure can be employed
in differentiating the genera ; it may be very small or conspicuously
longer than the entire funicle as in Orthoris, and its basal joint may
constitute from two-thirds of the whole to very much less; in Ce?i-
trinua acuniinatus, for example, the two basal joints together com-
pose less than one-half of the mass, with the first much shorter than
the second ; the basal joint is frequently subglabrous, at least toward
base, and especially in Baris with its immediate allies and in some of
the subgenera of Limnobaris ; in one of the subgenera of Centrinus
(Odontocorynus) it becomes conspicuously modified in the male.
The mandibles vary greatly in structure, from stout, thick, arcuate
and broadly decussate to the long, straight, prominent and perfectly
non-decussate, without trace of internal denticulation, the latter
type being nearly similar in shape, but not in plane of motion, to
those of Balaninus, showing that Centrinus and Balaninus may have
a certain obscure relationship apart from their general similarity of
form. In Eunyssobia and Plocamus they move in a nearly vertical
plane, precisely as in Balaninus, but in spite of all these resem-
blances I am of the opinion that Balaninus is more closely allied to
the Anthonomini, and that it should constitute a simple trilte in
that vicinity.
I have found the various modifications of the mandibles of posi-
tive value in delimiting the genera allied to Centrinus. It was the
opinion of Lacordaire that the forms assumed by the mandibles
were so erratic in this and allied tribes, as to be of very little use

in classification, and, assuming the definition and scope of certain
genera as known to this author, such as the Schonherrian Baridius
and Centrinus, there can be no doubt that he was entirely justified
in coming to the conclusion expressed in the foot-note on page 3,
vol. VII, of the "Genera." Whatever opinion may be held, how-
ever, concerning the usefulness of mandibular modifications for the
purposes to which they are here applied, it can only be said that I
have found the' generic groups defined by them to be quite homo-
geneous within themselves in external appearance and distinctly
separated from each other in general habitus, and these facts admit-
tedly constitute one of the best tests of generic validity. In addi-
tion we are enabled in this way to really define and fix some tangible
limits to the genus Centrinus, which has never been accomplished
by any other means. The fact that the prosternal sulcus and de-
gree of separation of the anterior cox« prove to be of uncertain
value for generic definition in Centrinus and its immediate allies,
because of the marked sexual divergencies in the conformation of
these ])arts in many species, taken in connection with the intro-
generic homogeneity of facies of the groups defined by mandibular
structure, prompts me to believe that we have here, at least, a prac-
tical solution of one of the most perj)lexing problems of the Cur-
culionida;.
The prosternum is subject to almost every possible modification ;
it may be either perfectly flat or variously foveate or longitudinally
sulcate to a greater or less degree. The sulcus when present does not
generally receive the beak in repose, but there are at least three
genera — Coleomerus, Diorymerus and Aulobaris — in which the beak
can be placed in the groove just as in any normal cryptorhynch, and,
in Coleomerus, the groove often extends posteriorly far into the meta-
sternura ; in the other two genera, however, it does not pass beyond
the prosternum. The apical margin is usually entire, but frequently
sinuate in the middle, and, at a short distance behind the apex, there
is a more or less distinct transverse constriction. The degenerative
remnants and modifications of the transverse constriction and longi-
tudinal sulcus or of a combination of the two, frequently give rise
to subapical foveae of various forms, sometimes continued posteri-
orly by folds of the surface.' The anterior cox* are of every
1 In some genera the two subapical fovese serve as receptacles for the robust
basal joint of the antennal funicle, when the beak is placed closely against
the body, these portions of the sulcus or constriction being therefore preserved
for a useful purpose.

possible degree of separation, from complete contiguity as in an
undetermined IJraziiian genus which I have before nie, to extreme
separation as in some of the madaride genera ; in our own genera
they are always more or less separated.
The pygidium plays an important part in the classification of the
Barini, but the weight attached to it was somewhat over-estimated
by LeConte, for the degree of exposure of this part, as well as its
relative departure from the vertical, often depends to a considerable
extent upon the sex of the individual. In Baris, for exarajjle, the
species as a rule have not only the pygidium, but in addition nearly
the entire propygidium uncovered in the male, the female having
merely the pygidium exposed. This sexual character is still more
pronounced in some of the centrinide genera, in which there are
many species having the pygidium exposed at a]iex in the male, but
entirely covered in the female, and, in two of the species, forming
the genus Centrinogyna, it is completely exposed, vertical and
unusually large in the male, but oblique and practically entirely
covered in the female. It is impossible, therefore, to divide the
tribe into two perfectly natural groups based upon pygidial struc-
ture, but the latter is nevertheless very useful in characterizing the
genera.
There are but few other points to which attention need be directed
at the present time, in view of what has been already published.
The eyes do not vary sufficiently to call for special remark ; they are
nearly always widely separated above and beneath, well developed
and finely faceted; in Coleomerus, however, they are narrowly
separated above.' The body is of nearly all possible shapes, from
extremely slender and cylindrical as in Barilepton and the Madopte-
rides through the oval and elliptical, convex and flattened forms, to
the extremely robust and strongly rhomboidal outline of Eurypages,
Diorymerus, Pachybaris and some other centrinides. _ The prothorax
is frequently tubulate at apex. The scutellum is very variable
in structure and vestiture. The met-episterna are narrow or broad,
the legs short or long, with the femora dentate beneath as in
many tropical types and, less distinctly, in our own Madarellus and
Pseudobaris, or completely unarmed as in the majority of genera;
the tibiie straight, or abnormal in structure as in Eisonyx, and almost
1 In the Australian Pl(iti//)h(eux lijterioides the eyes are said by I'ascoe to be
very coarsely faceted and contiguous beneath.
464 Coleopterological Notices, IV.
invariably with a short acute internal pjiur at the apex. The tarsi
may be shorter or longer than the tibiae generally with the third
joint dilated and bilobed, but occasionally also with the second as
widely dilated as the third as in Barinus ; in Calandrinus, Zaglyptus,
Eunyssobia and Plocamus the tarsi are very slender, with the third
joint not or scarcely wider than the second, while in Barinus bivif-
tntiis they are extremely broad. The tarsal claws may be connate
or divergent, rarely single; in Centrinus senilis Gyll., they become
robust, and excavated along the under surface; they are never
toothed, cleft or appendiculate, this being as singularly constant a
peculiarity of the Barini, as the seven-jointed antennal funicle.^
The structure of the abdomen is comparatively constant and of no
value in classification as far as can be observed ; the last three sutures
are always posteriorly reflexed at the sides.
The secondary sexual characters of the male are numerous, varied
and often of a decidedly radical nature. In many species of the
genus Centrinus, for example, the male has a long corniform process
before each anterior coxa and a deep prosternal fossa, while the
female is devoid of the processes, and may not only have the pro-
sternum flat or with a very feeble sulcus, but the coxte also more
widely separated. In some species of Centrinus, as before remarked,
the basal joint of the antennal club is the only part subject to second-
ary sexual modification in the male. In conformity with a general
rule in the CurculionidsB, the antennae are usually inserted relatively
nearer the tip of the beak in the male than in the female, the beak
being nearly always smoother, somewhat longer, Mess punctate, more
?lender and sometimes more strongly arcuate in the latter sex.
The abdomen generally has, near the base, a small, moderately deep
impression, as in many tribes not only of this but of other families.
Finallv, among the more special and singular secondary male cha-
racters, mention should be made of the dentate anterior trochanters
of Centrinus acuminatus and globifer, and of a very remarkable
structure which I have noticed in an undetermined Brazilian species,
the sides of the prothorax behind the apex having a large impres-
1 As a most notable exception, it should be stated that in the genus Enops
of Pascoe, the claws are described as bifid ; but the author appears to be in
some doubt as to the true affinities of Enops, and it is quite possible that it
will have to be referred to another tribe.
2 In Conoproctus there is an extraordinary reversion of this rule, the beak
in some species being much longer in the male than in the female.
Coleopterological Notices, IV. 4(j5
sion, in the middle of which there is an erect transverse row of long
acute spiniform teeth, the surface being perfectly smooth and normal
in the female ; there are doubtless many other special sexual cha-
racters of equal singularity among the tropical species ; one of these
will be noted under the genus Madarellus.

may be recognized as follows: —

Bariclitis SchiJnh. (pars).
This is a large genus of almost universal distribution, but much
more developed in North and South America than in Eurasia.
Assuming the definition of the genus given in the preceding table,
the species occurring within the territory embraced by the present
monograph are of an oval or oblong-oval convex form of body, with
semi-glabrous and usually strongly shining integuments. As com-
pared with most of the other genera of the tribe the sculpture is
rather coarse and only moderately dense. The vestiture consists
of small semi-erect or recurved sette, which are always sparse and
never broadly squamiform.
The rostrum is invaria))ly short, often excessively so, never quite
equalling the prothorax in length, and, in many cases, not more
than one-half as long. On comparing this form of beak with that
of Centrinus, Limnobaris or even Onj^chobaris, it can reasonably
l»e inferred that the hal)its of the species are notably, if not essen-
tially, ditferent from those of the latter genera.
470 Coleopterological Notices, IV.
The legs are veiy short, the tibia? strongly mueronate within at
apex, and more or less strongly carinate and grooved along the
sides, the tarsi moderate in development, with the third joint more
or less broadly bilobed or emarginate ; the ungues are somewhat
variable in length, but never very long.
Our species can be readily divided into two groups, which might
be considered of subgeneric value, were it not for the fact thai
B. caUida constitutes a connective bond in the important character
relating to the form of the scutellum. The first of these groups is
characterized by a robust form of body, a greater development of
the sparse setae, broadly sinuate external outline of the tibite, feebly
marked transverse impression at the base of the beak, and a trans-
verse broadly impressed scutellum, the other by a variable but
nearly always more slender form of body, less developed setaj,
straight tibiiB, strongly marked l)asal impression of the beak, and a
smaller subquadrate or rounded and unimpressed scutellum. In the
first, the anterior coxa? are always very narrowly separated, while
in the second they are generally much more widely so, although
never very remote when compared for example with Onychobaris,
their distance asunder being always less than their own width. I
find no appreciable difference between the groups in the nature of
the impression of the prosternum, the latter being very variable in
degree ; it is sometimes quite marked, but cannot well be made use
of in a tabular arrangement of the species. It occasionally disap-
pears completely.
The buccal opening is deep, and has, at the bottom, a long slender
truncate process, serving as a pedestal for the mentuni, the latter
being small and obconical. In the species of the first group the
sides of the buccal opening are more or less prolonged downward,
forming lateral plates for the protection of the oral organs, espe-
cially developed in strenua. In the second group, however, the sides
of the fissure are horizontal and perfectly continuous with the flat
under surface of the beak. The mandibles are small, stout, arcuate
and distinctly overlap when closed.
The sexual characters are more marked than in most of the other
genera with exposed pygidium, the male being nearly always easily
recognizable by the distinct impression at the middle of the abdo-
men toward base. It is somewhat singular that this impression, in
the present case, is always more sparsely and finely punctured than
the neighboring surface of the abdomen, while in Blapstinus, of the
(Joleopterological Notices, IV. 471
Tenebrioaida3, possessing an entirely analogous abdominal impres-
sion, which might at first sight be supposed to have been developed
from the same causes and for identical purposes, the impression is
almost always notably more densely punctured than the surround-
ing surface. The beak is not subject to great sexual modification,
although there are a few exceptions to this rule, as for instance
sparsa, in which it is distinctly shorter in the male than in the
female.
The following table probably includes a large proportion of the
forms inhabiting the United States : —
Tibise sinuate externally and prominent at apex ; anterior cox^ narrowly
separated ; impression between the head and beak feeble ; setae more
developed, generally bristling also from the under surface of the beak ;
scutellum usually short, transverse and broadly, deeply impressed, nearly
as in Trichobaris ; body never with seneous surface lustre 2

but never broadly sinuate ; anterior coxae more widely separated ; impres-
sion between the head and beak strong but always broadly angulate when
viewed in profile ; scutellum small, subquadrate or rounded, not broadly
impressed; setae generally inconspicuous ; surface lustre frequently aene-
ous 9

The sculpture in Baris varies to an extreme degree, and 1 have
before me specimens of transversa with the interstitial punctures
varying between wide limits, confused on all the intervals or form-
ing even series. I have been forced, however, to refer extensively
to sculpture in separating and describing the species, since this is
one of those enormously difficult genera containing a large number
of undoubtedly distinct species — as shown by extended series, —
which can only be distinguished by bodily facies, and which are
devoid of prominent structural differences, but the language em-
ployed should not be interpreted too rigidly, as it applies in general
only to the typical forms of a species. For example, the pronotal
punctuation m futilis and inconspicua is said in the table to be
dense, but there are specimens of both these species before me, in
which the punctures become separated by fully their own width, or
what might be termed sparse. In the case of isolated specimens,
therefore, a search for the proper identification in the table must be
more or less tentative, and it is quite possible that the table itself
may be misleading in those cases where I have had to take the
characters from single specimens. It has been \\\y constant care to
avoid synonymical repetitions, and, except in obvious cases, I have
Annals N. Y. Acad. Sci., VI, Sept. 1892.— 32

only accepted those species whicli could be demonstrated by lavg-e
series. The fact that nearly four hundred specimens have been
studied in composing the table, increases my belief that the number
of species at least has not been materially overestimated.
Baris as here considered also occurs abundantly in Brazil, and
the species taken on the banks of the Amazon and La Plata cannot
be distinguished in type from our own representatives. The genus,
even in its restricted sense, is therefore a very large one. The
European species have a distinctly different fades and should be re-
vised from the generic point of view ; the species are surely too
heterogeneous to be included in a single genus.
1 Baris ingens n. sp. — Oval, rather strongly convex, intense black
throughout, the integuments strongly shining. Head finely, sparsely punc-
tate, with a deep frontal fovea, the impression very feeble ; beak stout, evenly
and distinctly arcuate, coaisely strongly but not very densely punctate, three-
fourths as long as the protliorax, the setae long and bristling beneath ; antennae
rather long, the funicular joints less coarctate than usual, broad but obconical
near the club, the latter large, robust, the basal joint distinctly less than one-
half of the mass, transverse. Protliorax small, very nearly as long as wide,
the sides in basal two-thirds rather strongly convergent and nearly straight,
then broadly rounded, thence more convergent and slightly constricted to the
apex, which is scarcely two-fifths as wide as the base, the latter transverse,
the median lobe broad and strong ; disk with a very uneven and ill-defined
median line, the punctures very coarse and deep, abruptly perforate, one-half
as wide as the scutellum and generally separated by less than one-half of their
own diameters, each bearing a conspicuous fine cinereous seta. Scutellum
moderate, transverse, not strongly impressed. Elytra large, one-third longer
than wide, nearly two and one-half times as long as the prothorax, and, at
the large and longitudinally but not laterally prominent humeri, rather
abruptly almost one-third wider than the base of the latter ; sides parallel
and nearly straight in basal two-thirds, then gradually rounded to the apex,
which is somewhat parabolic ; disk with coarse, deep, strongly and not very
remotely punctured grooves ; intervals flat, one-half wider than the grooves,
each with a single uneven series of moderately large, deep, close-set punctures,
the setae moderate in length, slender, conspicuous. Abdomen rather sparsely
punctate, each puncture bearing a long cinereous and conspicuous setiform
liair, giving a strongly pruinose appearance by unaided vision. Anterior
coxae approximate, separated by scarcely one-fifth of their own width ; pro-
sternum not impressed. Length 7.3 mm. ; width 3 5 mm.

2 Baris striata Say. — Cnrc. 17, Ed. Lee, I, p. 281 (Baridius).
This is a rather common species of extended distribution, occur-
ring throughout the Mississippi and Missouri valleys, but not, to
my knowledge, extending to the Atlantic coast regions. The beak
is robust, strongly arcuate and quite distinctly shorter than the
prothorax, the latter relatively smaller than usual, fully one-third
wider than long, with the sides feebly convergent to apical fourth,
then strongly rounded and convergent to the apex, behind which
there is generally a feeble constriction; the punctures are very
coarse and generally separated by scarcely one-Iialf of their own
widths. Scutellum transverse and broadly impressed. Elytra
large, a little more than twice as long as the prothorax and abruptly
nearly one-fourth wider than that part, the humeral tuberosities
small but very distinct ; the stride are very coarse, deep and punc-
tate and the intervals are but slightly wider than the grooves, each
with a single uneven series of moderately coarse, very deep, close-
set punctures, the setfe moderate in length, erect and distinct but
not as conspicuous as in sfrenua.
The prosternuni is not impressed in front of the coxae, and the
latter are somewhat closer than in any other species which I have
observed, being separated by rather less than one-fifth of their
width. Length 4.8-5.5 mm. ; width 2.25-2.'! mm.
The series before me is from Arkansas, Wisconsin and Montana.

latter in the female. Prothorax subconical, more strongly narrowed
near the apex, convex, coar.<ely but not very densely punctate, the
punctures circular, about one-half as wide as the transverse scutel-
lum, and separated by their own diameters in some specimens, to
scarcely one-half that distance in others. Elytra large, fully twice
as long as the prothorax and nearly one-fourth wider than the latter,
the grooves exceedingly wide and deep, distinctly and remotely punc-
tate at the bottom, the intervals not at all wider than the grooves,
each with a single series of rather coarse very deep and distant
punctures, the second and third not wider, the seta3 very small,
visible, but not in the least conspicuous. Abdomen coarsely deeply
and closely punctured.
The male has the abdomen narrowly and deeply impressed nearly
through the length of the two basal segments, but in a small speci-

Colorado. Mr. Jiilich.
The type is a male, and has the al)donien rather narrowly and
distinctly impressed in the middle toward base. The peculiar pale
coloration may, in part at least, be due to immaturity, but the
species is remarkabl}' distinct in the coarse and squamiform nature
of the short and normally sparse setaj, these, as usual in the present
group, also bristling conspicuously from the lower surface of the
rostrum.

Texas (Big Springs). Mr. H. F. Wickham.
The single representative is a female and the species is allied to
strenua, differing however in many strongly marked features,
among which should be mentioned the much more obese form,
smaller, denser punctures, broadly confused on most of the elytral
intervals, the more prominent and subcariniform median line of the
pronotum and the relatively shorter beak.

The type is a female judying- by the entirely unimpressed abdo-
men, but in several of the species allied to this in general hal)itus,
the male se.xual characters become very feeble, so that it is occa-
sionally difficult to determine the sex of isolated individuals. The
present species is widely distinct although somewhat allied to niiida ;
it may be known, however, by its black legs, finer pronotal punc-
tures, less rhomboidal form of the body, larger scutellum, closer and
more transversely rugulose interstitial punctures, and more evident
seta3. The anterior coxte are sei)arated by one-half of their own
width.

head, straight and very feebly oblique from the moderately wide and rounded
median lobe to the sides ; disk strongly convex anteriorly and laterally, with-
out trace of median line, the punctures rather coarse, deep, well separated,
subperforate with the edges slightly obtuse, two-thirds as wide as the scutel-

The single male serving- as the type represents a species quite
closely allied to soluta, but differing in its slightly narrower form,
shorter beak, less coarse pronotal punctures and several other char-
acters. The abdomen is rather narrowly and very feel)ly impressed
in the middle toward base; the prosternum nearly flat, very widely
separating the coxa3. Floridensis may be distinguished from trans-
versa by its much sparser punctuation, narrower form, piceous el3'tra
and longer elytral seta3.

but deeply, densely so, rugose at the sides, robust, moderately arcuate and
about three-fourths as long as the prothorax ; antennse inserted distinctly be-
hind the middle, the scape very short, club moderate, its basal joint polished,
pubescent toward apex. Prothorax one-half wider than long, the sides just

The form of the prothorax, with the pronotum more declivous
anteriorly, shows that this very distinct species should be associated
with transversa and its allies. In the male the abdomen is broadly
and feebly but distinctly impressed near the base.

sparsely, minutely punctate, the beak more coarsely and closely so, densely
rugose at the sides, short, thick, arcuate, but slightly more than one-half as
long as the prothorax ; antennae moderately slender, the club rather small,
not one-half as long as the funicle, the first joint of the latter shorter than
the next three. Prothorax scarcely one-fourth wider than long ; sides broadly,
evenly arcuate, becoming nearly parallel toward base, the arcuation only
slightly stronger near the apex ; base three and one-half times as wide as the
head, the median lobe rather narrow, distinct ; disk somewhat coarsely, deeply

tate, the intervals each with a single row of rather large deep moderately dis-
tant punctures, somewhat confused on the second, third and fifth. Abdomen
strongly, rather closely punctured. Leys somewhat sparsely and feebly punc-
tate ; tibipe straight externally, the tarsal claws moderate. Length 3.8 unu. ;

Colorado.
The description is drawn from the male, the two basal segments
of the abdomen being strongly impressed in the middle. The pro-
sternum is feebly impressed and the coxte separated by rather more
than one-half of their own width. This species may be distin-
guished by the long, evenly rounded, strongly, densely punctate
prothorax, which is subequal in width to the elytra, and by the very
dull lustre of the entire upper surface. The pronotal punctures are
denser, and, especially, smaller than in transversa, which oblongiila
somewhat resembles in form and size.

New York, Indiana, Iowa, Missouri, Colorado and Texas. A
widely distributed, common and easily recognizable species. I think
that there is but little doubt that Say described transversa from
one of the numerous sculptural modifications of inter stitialis, but
as the species is more commonly known under the name transversa
and since the name "interstitialis^' refers to a form which has never
l)een accurately defined, and has always given rise to confusion and
uncertainty, even on the part of Say himself, the course here pur-
sued would appear to be for the best interests of science. Carinu-
lata is not tenable as a species, the smooth median line of the
pronotum being a most variable feature, as is also the interstitial
j»unctuation.

A moderately large, distinct and easily recognizable species, not
at all closely allied to any other Calitbrnian representative of the

The coarse deep rounded and close-set punctures, forming a single
series on each of the elytral intervals, is a type of sculpture which
forcibly reminds us of several species of Onychobaris, such as
stictica, but otherwise there is no resemblance. Aprica belongs in
the group containing transversa, but is not very closely related to
any other species. The abdomen in the male has a rather small but
distinct subbasal impression.

A comparatively small, convex, strongly and deeply sculptured
species bearing a general resemblance to transversa, but distinguish-
able by its much smaller size and the other characters given in the

feebly impressed. In the male the abdomen is narrowly and strongly
impressed toward base. In the female the pronotal punctures are
generally much closer, sometimes very dense, and the prothorax is
frequently subprominent at apical fourth ; the above described type
is a male from Iowa.

letely punctate, the beak rather coarsely but not very densely so at the sides,
rather stout but equal throughout, strongly arcuate and almost as long as the
prothorax ; antennae normal. Prothorax rather short, nearly one-half wider
than long ; sides subparallel and very feebly arcuate in basal two-thirds, then
strongly rounded, thence strongly convergent and nearly straight to the apex,
which is transverse ; base scarcely two and one-half times as wide as the head,
subtransverse and straight, the median lobe small and feebly developed ; disk
without median line, the punctures coarse deep and perforate, three-fourths
as wide as the scutellum, rather unevenly distributed but generally separated
by distinctly less than their own diameters, in apical fifth becoming abruptly
very minute. Scutellum rather small. Elytra about two-fifths longer than

the humeri just visibly convergent and very feebly arcuate, the apex evenly
rounded, the sutural notch normal ; disk with deep abrupt obsoletely punc-
tate grooves, moderate in width toward base, becoming much narrower toward
apex ; intervals rather wide, flat, each with a single series of small feeble
punctures, which become larger and close-set toward base but very minute and

Louisiana ; Missouri ; Indiana.
This small species can easily be identified by the peculiar punc-
tuation of the pronotum and abdomen as detailed in the description.
The prosternum is very feebly impressed and widely separates the
coxfe. The three specimens before me are apparently females, but
as they differ greatly in relative stoutness of form, it is possible that
the more slender specimen from Louisiana, assumed as the t_vpe,
may be a male, and that in that sex the abdominal impression is
obsolete.
27 Baris rubripes n. sp. — Oblong, moderately convex, highly polished,
piceous-black, the legs rufous. Head minutely, rather sparsely punctured,
with a small punctiform fovea in the transverse impression, the beak strongly,
moderately densely punctate, arcuate, about three-fourths ('J, ) to four-fifths
( 9 ) as long as the prothorax ; antennae somewhat less robust than usual, the
fanicle long, with the second joint a little longer than wide, the third feebly
transverse, club short but robust. Prothorax two-fifths wider than long, the
sides almost evenly and rather strongly arcuate from base to apex sometimes a
little more abriii^tly convergent near the latter ; base distinctly less than three
times as wide as the head, transverse, the median lobe narrow but pronounced ;
disk widest slightly before tlie base, with a rather wide distinct impunctate
area which is subentire ; punctures somewhat coarse, deep and dense, about
three-fourths as wide as tlie scutellum and separated by less than one-half
their diameters. Scutellum unusually small, subquadrate, slightly tumid.

not distinctly wider than the disk of the Ip-tter, the humeri feebly tumid ; sides
subparallel, the apex broadly but not \<dr'y abruptly rounded ; disk with deep,
abrupt and rather wide grooves, which are not distinctly punctate, the inter-
vals about twice as wide as the grooves, flat, each with a single series of coarse
but not very deep, close-set punctures ; setae very short but moderately dis-
tinct. Abdomen rather finely, decidedly sparsely punctured. Legs moderate,
somewhat strongly punctate ; tarsal claws rather long. Lengtli 3.2-4.8 mm. ;

California (Sonoma, Mendocino, Lal<e and Santa Craz Cos.).
This species somewhat resembles terniestriata in outward form,
but is distinguishable at once by the coarse grooves and large inter-
stitial punctures of the elytra. The abdomen in the male is feebly
impressed in the middle toward base, the prosternum narrowly and
distinctly impressed, and the anterior coxse separated by rather more
than one-half their width. The usual fine transverse groove bor-
dering the anterior margin of the prosternum is quite distinct. The
legs are sometimes darker and rufo-piceous in color. The large
series of examples before me displays an unusual diversity in size
but is otherwise quite homogeneous.

dius); Proc. Am. Pliil. Soc, XV, p. 293.
This is a small narrow species, dark rufo-piceous in color, polished,
with a feeble aeneous tinge and with dark rufo-testaceous legs. The
beak is rather slender, densely punctured, rather strongly arcuate,
subequal in length to the prothorax in the female, but only three-
fifths as long as the latter in the male. Prothorax rather elongate,
from one-fourth to one-third wider than long, subparallel and broadly
arcuate in basal two-thirds, then gradually convergent and straiglit
to the apex, the basal lobe rather prominent; disk with a narrow
but rather distinct subentire median line, the punctures deep strong
and somewhat coarse, moderately close in the original male type
and separated by nearly twice their widths, but rather closer in a
single female taken by me in northern California. Elytra with fine
but deep abrupt and impunctate striae, the intervals nearly three
times as wide as the grooves, perfectly flat, each with a single even
series of coarse but very feeble widely spaced punctures, the sette
minute and almost invisible. The prosternum is broadly, feebly
impressed and the anterior coxse separated by barely one-half of
their own width. Length 2.8 mm.; width 1.2 mm.
The above is an outline of the typical sparsa from Oregon and
northern California, and care must be taken not to confound it with
ruhripes from the vicinity of San Francisco, which is a larger
species, with narrower and much more densely and strongly punc-
tate elytral intervals and denser pronotal punctures.

closely punctate, the beak more strongly, densely so, rugulose at the sides,
very stout, arcuate, two-thirds as long as the prothorax ; antennae moderate,
the club large, robust, ovoidal, its basal joint polished and sparsely setose.
Prothorax large, scarcely one-fourth wider than long ; sides broadly, evenly
arcuate and convergent anteriorly, becoming nearly parallel in more than basal
half; base three and one-half times as wide as the head, oblique and nearly
straight from the scutellum to the basal angles, the median lobe very small
and feebly developed ; disk rather feebly convex, finely, densely, deeply punc-
tate, without trace of median impunctate line, the punctures rather less than
one-third as wide as the scutellum and separated by scarcely their own diame-

long. Elytra scarcely more than oue-third louger than wide, quite distinctly
less than twice as long as the prothorax, and, at the moderately tumid humeri,
a little wider than the latter ; sides subparallel ; apex broadly, rather abruptly
rounded; disk with rather narrow but very deep grooves, which are not dis-
tinctly punctate or crenulate, the edges slightly obtuse ; intervals polished,
nearly flat, each with a single series of coarse strong moderately approximate
and somewhat uneven punctures, rather smaller and more or less confused on
the second, third and fifth ; setae very small and scarcely observable. Abdomen
rather finely but strongly, moderately closely punctate. Legs moderate,
feebly, sparsely punctate, the tibiae straight along the external edge ; tarsal
claws rather small. Length 4.8 mm. ; width 2.3 mm.
California.
The single specimen is a male, and has the abdomen somewhat
narrowly and feebly impressed in the middle near the base. The
prosternum is very feebly impressed, and the coxae separated by
slightly less than one-half of their own width. The punctures of
the prothorax are relatively finer than in any other form known to
me, and the species is quite distinct in facies.

The peculiar form of the prothorax will always render this species
easily identifiable. The type is a female from North Carolina. I
have before me a single specimen from each of the above localities,
the interstitial punctures being- smaller in the Indiana female than
in either of the other two.

humeri, slightly wider than the latter ; sides behind the humeri subparallel ;
apex very broadly, evenly rounded ; disk with moderately coarse, very deep,
abrupt and finely but distinctly punctured grooves ; intervals flat, about twice
as wide as the grooves, each with a single somewhat uneven line of coarse,
very approximate and slightly rugulose piinctures, rather confused on the
third, those of the fourth and fifth fully two-thirds as wide as the correspond-
ing intervals ; setae small, suberect and forming quite distinct rows by longi-
tudinal oblique illumination. Abdomen rather coarsely deeply and closely
punctured toward the sides, more sparsely so in the middle of the first seg-

lu some respects this small species resembles aperta ; it differs in
its radically different shape of the prothorax, slightly smaller and
denser pronotal punctuation, and less minute and distant interstitial
punctures of the elytra; also in its more depressed form and rather
shorter beak.

Described from the female. This species does not seem to be
very closely allied to any other in general facies, but it is difficult
to make this clear from description only. It is distinguishable by
its sparsely, moderately coarsely punctate and somewhat depressed

The small size, rounded sides and densely, strongly punctured
surface of the prothorax, coarse grooves, and very fine distant inter-
stitial punctures of the elytra, will probably serve to identify this
species, which is of unusually cylindrical form. The presternum is

coxie by a little less than one-half of their own width. The unique
specimen is a female.

California (near San Francisco).
Among the six specimens before me a considerable amount of
variation is observable, especially in a rather large male which is
relatively stou.ter, with the prothorax as wide as any part of the
elytra, and having the sides parallel in basal three-fourths. The
peculiarity of the other discrepant form, which is an unusually large
female, lies in the fact that the elytral intervals are slightl}^ convex,
the pronotal punctures being densely crowded and contiguous, and
without vestige of impunctate median line. I have but little doubt,
however, that they belong to this species.
The description is taken from a male, the abdominal impression
being unusually wide and extending only slightly upon the second
segment. The sexual differences in the beak are hardly noticeable.

The form of this small and distinct species is unusually narrow,
rather more so in fact than any other true Baris which I have seen.
The beak in the male is moderately stout, deeply, closely punctate
at the sides, distinctly arcuate and about three-fourths as long as

A single pair, In the male the abdomen has a small and mode-
rately deep impression very near the base. The sexual disparity in
the form and length of the beak is rather unusual in Baris, although
common in those genera having a greater longitudinal development
of this part of the body ; it is also very noticeable in sparsa. This
species differs from serea, which it resembles in size, lustre and
elytral sculpture, in its narrower, more parallel form, longer, rather
more coarsely and decidedly more densely punctured pronotum, and
lono-er beak,

This species is one of the smallest of the genus, of moderately
stout convex form, and is always highly polished and quite strongly
seneous in lustre. The beak is short, robust, feebly arcuate and
about two-thirds as long as the prothorax, the latter rather trans-
verse, from one-third to two-fifths wider than long, and with the
punctures very sparse, somewhat fine, moderately deep and sepa-
rated by from two to three times their own diameters, without
median impunctate line. The scutellum is small, flat and almost
circular. The elytra are not quite twice as long as the prothorax,
rather distinctly narrowed behind the humeri, with fine but deep
and abrupt, minutely punctulate grooves, the intervals wide, flat,
and each with a single series of very minute, remote punctures, not
confused on the second or third. Length 2.3-2.9 mm.; width

short and transverse, two-fifths wider than long ; sides subparallel and just
visibly arcuate to apical third, then strongly rounded, thence strongly con-
vergent and distinctly sinuate to the apex, the latter very feebly arcuate, one-
half as wide as the base, the latter about two and one-third times as wide as
the head, transverse, the median lobe rather wide and distinct, rounded ; disk
without median line, the punctures fine but deep, sparse, about one-half as
wide as the scutellum and separated by two to three times their own diameters,
almost completely obsolete in apical fifth. Scutellum very small, nearly cir-
cular. Elytra scarcely more than one-fourth longer than wide, a little more
than twice as long as the prothorax, and, at basal third, very distinctly wider
than the latter ; sides parallel and feebly arcuate, the liumeri feebly tumid,
not at all prominent laterally ; apex broadly, almost semi-circularly rounded ;
disk very finely but deeply and abruptly striate, the strise not visibly punc-
tate ; intervals wide, flat, three to four times as wide as the strife, each with a
single series of excessively minute, feeble, remote punctures, which are only
observable under special conditions of amplification and illumination ; set<e
not observable under moderate power. Abdomen finely, sparsely punctate, the
metasternum quite coarsely, deeply and densely so. Anterior coxae rather
widely separated. Length 2.2 mm. ; width 1.0 mm.
Florida (southern). Mr. Jiilich.
The sex of the unique type is not evident, but the abdomen appears
Goleopferological Notices, IV. 505
to be very feebly impressed near the base. This is the smallest
species known to me, and is quite distinct, differing from the
form assumed to represent serea, in its smaller size, longer beak,
larger head, still stronger aeneous lustre, and more constricted pro-
thorax. The base of the pronotum is nearly three times as wide as
the head in serea, and the grooves of the elytra are much coarser,
the interstitial punctures being more evident; in seintillans the
latter are as nearly as possible completely obsolete.
43 Baris seneomicans n. sp. — Oblong-oval, somewhat depressed,
highly' polished, black throughout and with a strong reneous metallic lustre.
Head not distinctly punctate ; beak finely but deeply punctate, the punctures
sparse even at the sides, thick, strongly arcuate, very nearly as long as the
prothorax ; antennae somewhat slender, the club not very large. Prothorux
widest before the base, transverse, fully one-half wider than long, somewhat
inflated, the sides subparallel in basal three-fourths and strongly arcuate,
then moderately convergent and feebly sinuate for a short distance to the apex,
which is transversely truncate ; base a little less than three times as wide as
the head, straight and feebly oblique from the small and feeble median lobe
to the basal angles ; disk with a narrow and feebly defined but subentire
median line, the punctures coarse and rather sparse, deep and perforate,
about one-half as wide as the scutellum and separated by nearly their own
diameters. Scutellum moderate, subquadrate, not longitudinally impressed.
Elytra two-fifths longer tlian wide, quite distinctly more than twice as long as
the prothorax, and, at the rather large and tumid humeri, very slightly wider
than the disk of the latter ; sides feebly convergent from behind the humeri,
the apex almost evenly and semi-circularly rounded ; disk with rather narrow
but abrupt and very deep, finely, remotely punctate grooves, the intervals
flat, rather more than twice as wide as the grooves, each with a single even
series of small but distinct, widely distant punctures, which are not at all
confused on the second or third ; setae very minute and almost completely
invisible. Abdomen not very finely but feebly and very sparsely punctured.
Legs rather coarsely and deeply but sparsely punctate ; tibiae straight ; tarsal
claws small. Length 3.5 mm. ; width 1.65 mm.
Massachusetts.
A decidedly distinct species, distinguishable by the bright aeneous
lustre, sparse punctuation, short, laterally arcuate prothorax and
somewhat depressed form. The prosternum is feebly impressed
and widely separates the coxae. The single specimen is apparently
a female.
44 Baris liyperion n. sp. — Feebly rhomboid-oval, convex, highly
polished and with a strong bronzy-seneous lustre; legs black; setae very
minute, sparse and inconspicuous. Head extremely minutely, sparsely punc-
tate, the beak more strongly but not closely so, very robust, arcuate, flattened

wide as the scutellum and generally separated by about their own diameters.
Scutellum small, quadrate, scarcely at all impressed. Elytra but little wider
than the i^rothorax, about twice as long as the latter ; humeri rather promi-
nent ; sides distinctly convergent ; apex obtuse ; strife moderately fine, deep,
abrupt, the intervals nearly fiat, fully twice as wide as the grooves, each with
a single series of fine, rather distant punctures, the second, and especially the
third, much wider, the latter with the punctures confused. Abdomen finely,
sparsely punctate. Prosternum strongly impressed along the middle, sepa-
rating the cox£e by two-thirds of their own width. Length 3.5—4.0 mm. ;
width 1.65-2.0 nun.
Florida.
Somewhat related to eeneomicans, but easily distinguishable by
its more elongate, more finely punctate prothorax, with the sides
much less rounded, and by its relatively shorter beak.
45 Baris Vitreola n. sp. — Oblong-oval, rather robust, moderately con-
vex, highly polished throughout, black with a strong aeneous lustre, the elytra
and legs rufo-piceous ; setse extremely minute and scarcely visible. Head just
visibly and very remotely punctulate, the transverse impression moderate ;
beak very stout, cylindrical, flattened toward apex, finely but strongly, rather
densely punctate, strongly, evenly arcuate and almost as long as the protho-
rax ; antenuc-e moderate, the club small, oval, with the basal joint polished.

twice as long, oblong, the sides behind the feebly prominent humeri just
visibly convergent and slightly arcuate ; apex broadly obtuse ; strise rather
strong, deep, abrupt, finely punctured, the intervals fiat, fully twice as wide
as the grooves, each with a single series of very fine remote punctures, the
third scarcely wider tlian the others. Abdomen sparsely punctate toward the
middle, rather closely so laterally, the punctures becoming large but shallow.
Prosternum strongly impressed along the middle, separating the coxie by
three-fifths of their own width. Length 3.4 mm. ; width 1.75 mm.

Florida.
The unique typo is a male, the abdomen being broadly and rather
strongly impressed in the middle toward base. There is no species
very closeh" allied to vitreola, but punclivenhHs appears to approach
it more closely than any other.
46 Bai'is ancilla n- sp. — Oval, not very stout, convex, strongly shining,
the elytra with a scarcely perceptible alutaceous lustre; body black through-
out, with a feeble bluish metallic lustre ; setfe minute, extremely sparse and
inconspicuous. Head excessively minutely, sparsely punctate, the beak more
strongly but not very densely so, very stout, arcuate, gradually and feebly
flattened toward apex, distin(;tly shorter than the prothorax ; antennje inserted
a little behind the middle, the club moderate, with the basal joint polished
and constituting rather less than one-half of the mass. Prothorax one-third
wider than long, the sides evenly rounded and convergent in ajjical third,
becoming nearly straight and parallel thence to the base, the latter twice as
wide as the apex, feebly oblique at each side of the small but distinct, rounded
median lobe; disk without impunctate space, the punctures strong but not
coarse, about one-half as wide as the scutellum and generally separated by
rather more than their own diameters. Scutellum small, quadrate, unim-
pressed. Elytra slightly wider than the prothorax and nearly twice as long,
the humeri but feebly prominent ; sides feebly convergent, gradually parabolic
in apical third, the sutural notch strong, broadly angulate ; striae moderate,
deep, even ; intervals flat, a little more than twice as wide as the grooves,
each with a single series of fine feeble and remote punctures, the second and
third wider but similarly punctate. Under surface and abdomen jeneous in
lustre, the latter sparsely punctate. Prosternum sulcate, rather widely sepa-
rating the anterior coxse. Length 3.3 mm. ; width 1.(5 mm.
Florida.
This species is slightly larger than confinis and differs in its
much sparser punctuation; from serea it differs in its more elon-
gate form, much larger size, wider elytral intervals and finer striae,
and from exigua, to which it appears to be more closely allied, it
may readily be known by its much finer and more remote intersti-
tial punctures, longer and less rounded prothorax, with less oblique
base, larger size and several other characters.

at apical fourth ; base not quite three times as wide as the head, straight and
distinctly oblique from the very small and feeble median lobe to the sides ;
disk finely but distinctly, sparsely and somewhat unevenly punctate, with a
narrow, feebly defined median line, the punctures less than one-half as wide as
the scutellum and separated by two or three times their own diameters. Scutel-
lum small, almost circular. Elytra two-fifths longer than wide, not quite twice
as long as the prothorax, and, at the feebly tumid humeri, slightly wider
than the latter ; apex broadly, rather abruptly rounded ; disk with somewhat
coarse, deep, obsoletely punctate grooves, the intervals Mat, generally but
slightly wider than the grooves, each with a single series of minute but quite
visible, remote punctures, the third interval much wider and with the punc-
tures broadly diffused ; setae extremely minute, inconspicuous. Abdomen finely
but rather strongly, sparsely punctate. Legs dark rufo-piceous in color, feebly
and sparsely punctate. Length 3. '3—4.1 mm.; width 1.5-1.9 mm.
Florida (Fernandina). Mr. Schwarz.
The prosternum is rather narrowly and quite stronply subsulcate,
and separates the coxas by scai'cely one-third of their own width.
This is a distinct and easily recog'nizable species, but as it differs
so radically from Say's description of interstitialis in the nature of
the elytral punctuation, I do not think that it can be placed near
that species; the latter is here regarded as being identical with
transversa. In regard to Bohemau's inter stitialis, there must
always be more or less doubt until the type can be compared, as
there are several of these peculiar sparseh' pun2tured Florida species,
which will equally satisfy his description.
48 Baris exigua. n. sp. — Oblong-oval, moderately convex, shining and
piceous-black throughout. Head very minutely and obsoletely punctate, the
beak rather coarsely and somewhat densely so, short, arcuate, three-fourths as
long as the prothorax ; antennae moderate, normal, the first joint of the club
polished and sparsely setose. Prothorax nearly one-half wider than long,
widest before the base, the sides evenly, rather strongly arcuate, the apex
broadly arcuate and continuous with the sides, the apical angles entirely
obsolete ; base nearly three times as wide as the head, straight and slightly
oblique from the feeble median lobe to the sides ; disk without trace of median
impunctate area, the punctures fine but deep, not very dense, about one-half
as wide as the scutellum and separated by distinctly more than their own
diameters. Scutellum very small. Elytra two-fifths longer than wide, twice
as long as the prothorax, and, at the feebly tumid humeri, very slightly wider
than the disk of the latter ; sides behind the humeri just visibly convergent,
the apex broadly rounded, the sutural notch large and quite deep ; disk with
fine but deep, abrupt, finely, remotely punctured grooves, which are feebly
creuulate near the base ; intervals flat, nearly tliree times as wide as the
grooves, each with a single series of fine but distinct, widely spaced punc-
tures. Abdomen finely, sparsely punctate. Legs rather distinctly, moderately

Texas (near Austin).
The singular form of the prothorax, evenly rounded from the sides
throughout the apex, the fine pronotal punctures, rather depressed
form and small size, will readily distinguish this species. The pro-
sternum is narrowly, feebly impressed, and separates the coxae by
much more than one-half of their own width. The elytral setse are
very minute and almost invisible under moderate power.
PLESIOBARIS n. gen.
The species of this genus are for the most part small, generally
quite minute, and for this reason will possibly prove to be some-
what numerous, especially as they are essentially characteristic of
our comparatively unexplored extreme southern fauna. One or two
species are known to occur in the more northern parts of the United
States, but the majority will probablv be found to inhabit subtropi-
cal Florida extending perhaps to Cuba.
The various representatives were regarded by LeConte as forming
part of the genus Pseudobaris, but certainly cannot be appropriately
placed there, because of their non-sulcate prosternum, moderately
separated coxas and small but perfectly free claws. They agree well
together in the general nature of the vestiture, this being densely
squamiform at the base of the third elytral interval, on the meso-
and metasternal side-pieces, and at the sides of the last three ventral
segments; elsewhere on the dorsal surface the large scales are sparse,
and variously distributed according to the species.
The few forms here brought to notice already fall into two groups
of almost subgeneric value, which however I will simply indicate
in the following table: —
Basal joint of the antenna! club large, composing at least one-half of the
mass ; body cylindrical, the elytral humeri not exposed ; elytra each
with a large sparsely squamose area behind the middle.
Black, the base of the prothorax rather strongly bisinuate; legs rufo-pice-
ous ; rostrum shorter than the prothorax 1 T-signillU
Piceousblack ; legs rufous, with the knees black ; base of the prothorax
transverse, just visibly and broadly bisinuate ; very small species.
2 sigiiatipes
Rufo-testaceous, the elytral suture clouded with black ; base of the protho-
rax very broadly and feebly bisinuate; larger species 3 albilatllS
510 Coleopterological Notices, IV.
Basal joint of the club short, composing one-third of the mass or even less ;
elytra not continuous with the prothorax at the sides, the humeri more
or less exposed and oblique ; body and legs intense black throughout.
Pronotum with a regular but sparsely squamose design, the scales sparsely
scattered over the elytra toward the sides, and also more or less distinctly
clustered in several small spots on the third and fifth intervals.
4 aeiniila
Pronotum without regular squamose design, the elytral vestiture consisting
entirely of minute inconspicuous setae which become slightly more robust,
but scarcely squamiform, toward the sides, and with a squamose spot at
the base of the third interval 5 disjlincta

Pennsylvania — Bobenian. There are but few statements con-
cerning this species, which can be made with any degree of cer-
tainty. It however undoubtedly belongs to the present genus, and
is probably also a member of the olbilatas division, having the elytra
cylindrical and continuous in outline with the prothorax at the sides.
The omission of exact measurements of length and width is a
serious defect in the great work of SchiJnherr.
2 Plesiobaris Signatipes n. sp.— Subcylindrical, convex, polished,
piceous-black, the legs slightly paler, more rufous with the knees black, ves-
titure extremely minute and inconspicuous with the exception of a few large,
widely scattered, white scales toward the middle and sides of the pronotum,
a denser lineolate spot of the same at the base of the third elytral interval,
and, behind the middle, a short even row of widely spaced scales on the second,
third and fourth intervals, also a few widely distant scales on the fifth inter-
val ; on tlie under surface the meso- and metasternal side-pieces are densely
clothed throughout with large white scales and also the last three abdominal
segments laterally. Head and beak sparsely, feebly punctured, the latter
moderately robust, feebly flattened toward apex, strongly, evenly arcuate and
fully as long as the prothorax, the antennse moderate, the joints of the funicle
slightly convex at the sides, the second and third subequal and about as long
as wide, the club small, briefly ovoidal, the basal joint composing fully one-
half of the mass. Prothorax one-fifth wider than long, the apex feebly arcuate
and two-thirds as wide as the base, the latter transverse, the median lobe
br.oad and exceedingly feeble ; sides parallel and straight to apical fourth,
then rounded, thence straight and not at all constricted to the apex; disk
with a rather wide but ill-defined impunctate line, the punctures rather large,
one-half as wide as the scutellum but very feeble and sparse, separated by
more than their own widths, becoming minute and still more feeble toward
the apex, and also near the base except in the middle. Scutellum very small,
subogival. Elytra barely twice as long as the prothorax and exactly equal
to the latter in width, the sides straight and continuous, broadly but not

abruptly romided behinrl ; humeral tuberosities very small and feeble, not at
all evident laterally; disk with very fine, moderately deep strife, the inter-
vals flat, four or five times as wide as the strife, the second and third sensibly
wider, each with a series of minute, feeble, distant and indistinct punctures.
Abdomen very minutely, obsoletely and sparsely punctured toward the middle.
Prosternum flat, not sensibly impressed, separating the somewhat small coxfe
by about two-thirds of their own width. Length 1.75 mm. ; width 0.6 mm.
Florida (Tampa). Mr. Schvvarz.
The antennal differences between this species and diyancla are
very radical in the structure of the club, but I can perceive no other
divergencies of a g'eneric nature, and parallel inconstancy of this kind
is well known in Onychobaris. Signatipes approaches more closely
to the published characters of T-aignum, than other species which
I have seen, but differs in its piceous color, apparently sparser pro-
notal punctures and in several other characters, among the more
importnnt of which is the form of the basal line of the prothorax,
said to be rather profoundly bisinuate in T-aignum.
3 Plesiobaris albilatiis Lee. — Proc. Am. Phil. Soc, XV, p. 298
(Pseudobaris).
Oblong-cylindrical, convex, polished, rufo-testaceous in color, the
beak, under surface, knees and elytral suture piceous-black ; punc-
tures of the upper surface bearing very minute and inconspicuous
setae, with a few large scattered whitish scales toward the middle
and sides of the pronotum, and a denser spot of the same at the
base of the third elytral interval, the remainder of the elytra with a
few large widely dispersed scales arranged subtransversely, and of
which a loose spot on the second and third intervals is more distinct ;
meso- and metasternal side-pieces and lateral portions of the last
three ventral segments abruptly very densely squamose. The beak
is robust, strongly arcuate and fully as long as the prothorax, the
antennie slender, the funicle long, with joints two to four a little
lonuer than wide and decreasing very slightly in length, the club
small, with the basal joint composing distinctly more than one-
half of the mass. Prothorax one-third wider than long, the sides
parallel and nearly straight to apical fourth, then convergent and
constricted, the base broadly and very feebly bisinuate, the disk
with a wide but uneven impunctate line, the punctures rather
coarse, deep and somewhat dense. The elytra are as in signatipes,
but with the intervals equal and about four times as wide as the
grooves. The prosternum is broadly, scarcely perceptibly impressed

width. Claws small, entirely free. Length 2.2-3.1 mm.; width
0.9-1.3 mm.
Florida (Tampa, Baldwin and Enterprise). The disposition of
the scanty vestiture is somewhat remarkable ; for example, on the
fifth interval each puncture bears a minute and simple seta, but
every third or fourth puncture l)ears instead, a very large fan-shaped
scale placed in a transverse position. In spite of the great differ-
ence in size the present species and signatipes are closely allied.
In the species of this group the scattered scales seem to be easily
removable, while in semula they are exceedingly persistent.
4 Plesio1>aris aemilla. n. sp. — Snbcylindrical, strongly convex, shin-
ing, deep black througliout, the vestiture consisting of short broad white scales
which are large in the dense spots, but elsewhere small ; the scales are only
present on the pronotum in an anteriorly dilated lateral vitta, which is pro-
longed inwardly along the basal margin almost to the middle, then abruptly
flexed anteriorly and outwardly as a narrow line terminating at lateral third
and middle of the length ; on the elytra the scales are condensed in four small
almost equidistant spots on the third interval, of which the basal is the largest,
and thence to the side margins are widely but almost evenly scattered, but
sometimes forming three spots on the fifth interval ; on the under surface they
are very dense on the meso- and metasternal side-pieces, and at the sides of
the last three ventral segments. Head and beak not very strongly punctured,
the latter short, very thick, .strongly arcuate and subequal in length to the
prothorax, the antennae inserted a little beyond the middle, the basal joint of
the funicle short, not twice as long as wide, the second and third very short,
subequal, the club about as long as the preceding six, with its basal joint
composing one-third of the mass. Prothorax one-third wider than long, the
sides parallel and straight in basal three-fourths, then broadly subangulate,
thence convergent, nearly straight and not at all constricted to the apex,
the latter truncate and two-thirds as wide as the base, the latter transverse
almost straight, the median lobe subobsolete ; disk without median line, the
punctures deep, moderate in size, very dense but not crowded. Scutellum
very small, rounded. Elijtra more than twice as long as the prothorax and
a very little wider, parallel, parabolic in apical third, very finely but deeply
striate, the intervals flat, moderately wide the third and fifth much broader
than the others, each with a series of small feeble rather distant punctures ;
humeral tuberosities very feeble. Prosternum flat, separating the coxfe by
rather more than their owu width. Length 1.6-1.7 mm. ; width 0.65-0.7 mm.
Florida. Mr. E. A. Schwarz.
This species was confounded by Dr. LeConte with the Zimmer-
mann specimen from South Carolina, identified by him as T-signum
Boh., and referred to below under disjuncta. It is a much smaller
Coleopterological Notices, IV. 513
species, and is not at all allied to the form mentioned. It was
apparently taken in great abundance.
Among the specimens before me there is one which is singuliirlv
deformed, the pronotum having, near the base and at lateral fourth,
a prominent polished wart-like tubercle. For a considerable dis-
tance around the tubercle, the small normal squamules are entirely
absent but replaced by large scale-like plates, concave or umbilicate
in the centre, each of which completely fills a puncture.
5 Plesiobaris disjuiicta n. sp. — Suboylindrical, very slender, con-
vex, black throughout, strongly shining, sparsely clothed with very small
setaB, especially evident but not at all conspicuous toward the sides of the
pronotum, very minute and sparse throughout on the elytra, the latter with a
small elongate spot of white squamules at the base of the third interval, the
meso- and metasternal side-pieces and sides of the last three ventral segments
also densely squamulose, the remainder of the under surface subglabrous.
Head very feebly, sparsely punctate, the impression rounded, feeble ; beak
shining, finely, deeply, moderately densely punctate, rather stout, cylindrical
somewhat strongly, evenly arcuate, a little longer than theprothorax ; antennse
moderate, the club rather large, as long as the preceding six joints combined,
the latter short and coarctate. Prothorax about one-fourth wider than long,
the sides feebly divergent and nearly straight from the base almost to the
apex, then rounded for a short distance, the subapical constriction very small
and feeble ; apex truncate, nearly as wide as the base, the latter broadly,
very feebly bisinuate ; disk with moderately coarse, deep, perforate punctures
which are almost contiguous, the impunctate line narrow and feebly defined,
only visible toward the centre. Scutellum small. Elytra at the base abruptly
quite distinctly wider than the prothorax, rather more than twice as long as
the latter, the sides parallel and almost straight, somewhat abruptly, acutely
ogival in apical third ; humeri obliquely rounded, the callus not conspicuous ;
disk with fine strife, becoming coarse near the base, the intervals two to three
times as wide as the striae, each with a single series of fine remote punctures,
becoming closer and more distinct toward base. Abdomen rather strongly,
coarsely and closely punctured, especially toward base. Prosternum broadly,
feebly impressed, separating the coxae by quite distinctly less than their own
width. Length 1.7-2.1 mm. ; width 0.6-0.8 mm.
Michigan ; Missouri ; Indiana ; South Carolina.
This species was considered by LeConte as possibly representing
Bohenian's Baridius T-signum, but it is evidently a widely different
species. The original description of T-signum includes the phrase
"elytris antice thoracis basi non latiora," and also states that the
rostrum is shorter than the i)rothorax, the elytra having a small
sparsely squamose maculation behind the middle, and the legs rufo-
piceous. One of the most conspicuous characters of disjuncta relates
514 Coleopterological Notices, IV.
to tlie form of the humeri, the elytra being abruptly much wider
than the base of the prothorax, and in the type there is no trace of
a squamose raaculation behind the middle of the elytra, nor any
indication of such a spot, as all the punctures are occupied by small
slender setae.
PYCIVOBARIS n. gen.
In many respects this genus is allied to Baris, but its species have
a distinctly different habitus due to the scaly vestiture. In its
structural characters, it is similar to Baris in the form of the anten-
nal club with its basal joint polished and composing fully one-half
of the mass, also in its short robust beak and free tarsal claws. The
fiat prosternum separates the coxfe rather more widely than in any
species of Baris, and in this peculiarity it approaches Onychobaris ;
the fine and abrupt frontal groove differentiates it, however, from
both of these genera and allies it with Stictobaris, from which again
it differs in its robust convex body and non-tubulate prothorax. The
prothorax is more distinctly constricted near the apex than in Baris,
but is never tubulate.
The l)eak is always shorter than the prothorax, the epistomal lobe
short, truncate and limited at each side by a small oblique fissure
as in Baris. Mandibles well developed, arcuate, overlapping in
repose and deeply notched at apex. The buccal opening is rather
smaller than in Baris, and its plane is more oblique to the under
surface of the beak behind it. The scutellum is quite different from
that of the last-named genus being distinctly bisinuate at apex.
Tarsal claws rather long, widely divergent.
Our two species may be defined as follows: —
Vestiture rather sparse, the whitish scales very narrow, producing merely a
decided pruiiiose appearance 1 pi'lliliosa
Vestiture dense, the scales broad, almost entirely concealing the surface.

STICTOBARIS n. gen.
The few components of this genus are distinguished by a rather
depressed body, extremely coarse and deeply perforate sculpture
of the pronotum, and a rather short prothorax which is strongly
tubulate at apex. The anterior cox* are large and somewhat nar-
rowly separated. Although the prosternum is feebly impressed, a
certain decided relationship with Onychobaris is- rendered evident
by the two deep fovete situated near the apex. It resembles Baris
in the large basal joint of the antennal club, though this is not a
character of decisive generic import, but differs from both the genera
referred to in the deep and abrupt transverse frontal groove or con-
striction.
The beak is rather short and stout, with the epistomal lobe short
and broadly sinuate at apex and the mandibles somewhat well de-
veloped, arcuate, notched at apex and partially decussate when
closed. The vestiture consists simply of rather long sparse stout
semi-erect and whitish or yellowish-white sette or setiform squani-
ules, which are sometimes denser on the second to fifth elytral
intervals behind the middle, a character heretofore noticed in one
of the groups of Plesioljaris, and also occurring in several species
of Centrinus.
The three known species may be thus distinguished : —
Set* moderate in length, yellowish, condensed at the base of the third interval
and also on intervals two to five in a rather large area behind the middle ;
body oblong ; legs rufous 1 cribrata
Setae longer, more robust and whiter, not in the least condensed at the jjoints
mentioned under the preceding species.
Body rather robust, oblong, obtusely rounded at apex ; beak densely punc-
tate; legs black 2 piinalis
Body narrow, rather narrowly rounded behind ; size much smaller ; beak
more sparsely punctate; legs rufous 3 subacuta

(Onychobai'is}.
Oblong-oval, somewhat depressed, shining, blackish-castaneous,
the legs ferruginous ; setae somewhat robust, moderate in length,
yellowish-white, more especially evident toward the sides of the
prothorax, in a dense humeral spot and another one more elongate
at the base of the third interval, also more or less distinctly denser
on intervals two to five in a limited area behind the middle. The
beak is robust, strongly arcuate and quite distinctly shorter than
the prothorax, the antenna3 moderate, the funicle thick, the club
rather robust but not large, the basal joint composing fully one-half
of the mass, with the pubescence moderately dense. The prothorax
is two-fifths wider than long, with the apex strongly constricted and
tubulate, the median line narrow and ill-defined, and the punctures
]terforate, deep, fully three-fourths as wide as the scutellum, uneven
in distribution but generally separated by nearly one-half their
own diameters. Elytra distinctly more than twice as long as the
prothorax, the intervals subequal, about one-half wider than the
grooves, the third a little wider. The prosternum is not distinctly
impressed and separates the rather large coxae by scarcely more than
one-half their own width. Length 3. -3-4.0 mm. ; width 1.4-1.7 mm.
Texas (Waco). Cab. LeConte. Easily recognizable by the pecu-
liar arrangement of the elytral setffi.
2 Stictobaris pinialis n. sp. — Oblong, subdepresserl, shining, intense
black throughout and sparsely, evenly clothed with rather long, robust, per-
fectly white setae, without trace of condensation, except feebly on the anterior
declivity of the humeral callosities. Head finely, very sparsely punctate,
glabrous, the groove narrow and deep ; beak robust, densely and deeply
punctate throughout, densely setose, without trace of impunctate line, feebly
arcuatej almost as long as the prothorax in the female, but quite distinctly
shorter in the male ; antennse moderate, the scape rather long, the second
funicular joint but very little longer than the third, outer joints gradually
very thick and subcontinuous in outline with the club, the latter moderately
robust, with the basal joint constituting rather more than one-half the mass.
Prothorax two-fifths wider than long, the sides subparallel or very feebly con-
vergent and nearly straight to apical fourth, then abruptly, strongly rounded
and almost transversely convergent to the constriction, which is very strong,
the apex strongly tubulate, truncate and three-fifths as wide as the base, the
latter subtransverse, the median lobe moderate, rounded and distinct ; disk
with extremely narrow and imperfect impunctate line, the punctures very
coarse, deep and dense, three-fourths as wide as the scutellum and more or
less polygonally crowded. Scutellum moderate, slightly wider than long,

impressed along the middle. Elytra slightly wider than the prothorax and
distinctly more than twice as long, the humeri not prominent laterally ; sides
subparallel, generally feebly arcuate, the apex somewhat obtusely rounded;
disk with moderate striae, becoming coarse near the base, the intervals flat,
slightly unequal, two to three times as wide as the stripe, rather finely, not
densely, somewhat rugulosely and confusedly punctured throughout. Abdomen
finely, sparsely punctate. Prosternum broadly and very feebly impressed,
with two deep subapical fovese as in Onychobaris, but less distant ; coxae
large, separated by scarcely more than one-half of their own width. Length
3.5-4.3 mm. ; width 1.45-1.8 mm.
Arizona.
The four specimens in my cabinet form a perfectly homogeneous
series, and represent a species differing greatly from cribrata in the
white pubescence, uniformly distributed and without trace of con-
densation behind the middle or at the base of the third interval, also
in its larger size, denser pronotal punctures and completely black
bod}^ and legs.
3 Stictobaris Sllbacilta n. sp. — Elongate-elliptical, convex, shining,
piceous-black, the legs rufous ; setae long, very robust, uniformly distributed
and without trace of condensation at the base of the third interval or behind
the middle. Head very finely, sparsely and feebly punctate, minutely reticu-
late and alutaceous, the groove rather shallow but distinct ; beak somewhat
coarsely but sparsely punctate, moderately strongly arcuate and subequal in
length to the prothorax ; antennae moderate, the club somewhat robust, nor-
mal, the second funicular joint short and but slightly longer than the third.
Prothorax scarcely one-third wider than long, feebly convergent and nearly
straight at the sides to apical fourth, then abruptly, strongly narrowed and
tubulate, the apex truncate and fully two-thirds as wide as the base, the latter
transverse, the median lobe small and rather feeble, rounded ; disk with a
very narrow, incomplete and subobsolete impunctate line, the punctures
nearly as in cribrata, but rather closer. Elytra one-fourth wider than the
prothorax and nearly two and one-half times as long, the humeri feebly
tumid, not prominent laterally ; sides parallel and feebly arcuate ; apex
gradually, rather narrowly parabolic ; disk with somewhat narrow, moder-
ately deep striae, becoming coarser and somewhat crenulate near the base, the
intervals flat, from one-half wider than, to nearly twice as wide as, the grooves,
the punctures arranged in nearly even single series, fine and remote but be-
coming very coarse and rather close-set toward base, more or less confused on
the third. Length 3.2 mm. ; width 1.25 mm.
New Mexico (Las Yegas).
Closely allied to cribrata, but well distinguished by its much
narrower and more convex form, less truncate elytra, more elongate
prothorax, and especially by the much longer, still more robust and

whiter seta3, without trace of condensed spots. In cribr-ata the
third interval is not only more densely setulose, but appears also to
l)e feebly elevated toward base.
TREPOBARIS n. gen.
The single species representing this genus is narrow, elongate-
oval and subcylindrical in form, resembling somewhat a very elon-
gate Aulobaris, and perhaps really allied more closely to that genus
than to any other. The prothorax is more elongate and parallel
than in Aulobaris, and is briefly tubulate at apex, and in antennal
structure it differs from the genus in (juestion by its normally short
second funicular joint and longer club, and in tarsal structure by
the much smaller third joint, not wider than long though distinctly
wider than the preceding.
As in Pseudobaris, the prosternum is very deeply and abruptly
sulcate, the sulcus being much too narrow to receive the beak, and
this is another important feature distinguishing it from Aulobaris.
The sulcus is of somewhat peculiar form, being moderately and
gradually dilated anteriorly and narrowest at a point just before
the coxae, a contour which suggests a line of development parallel
with that of Aulobaris nnso.
1 Trepobaris elongata n. sp. — Elongate, subcylindrical, convex,
highly polislied and deep black throughout, the setse of the upper surface
excessively minute, the third elytral interval without trace of squamules at
base ; setae of the under surface very small, erect. Head convex, finely,
sparsely punctured, the transverse impression strong, obtusely angulate in
profile ; beak rather stout, sparsely punctate, rather strongly arcuate at the
base, but feebly so thence to the apex, equal in length to the head and pro-
thorax in the male ; antennse moderately slender, the basal joint of the funicle
long, the second not twice as long as wide, scarcely one-half as long as the
first and much shorter than the next two, the club rather large, oval, densely
pubescent, as long as the five preceding joints together and with its basal joint
constituting but little more than one-third of the mass. Prothorax very nearly
as long as wide, the sides just visibly convergent and nearly straight to apical
fourth, then broadly rounded and feebly convergent to the fine apical constric-
tion, the apex very briefly tubulate, truncate and fully three-fifths as wide as
the base, the latter transverse, the median lobe almost completely obsolete ;
disk not very coarsely punctate, without Impunctate line, the punctures
scarcely one-third as wide as the scutellum and separated hy fully their own
diameters toward the middle, close but not rugulose at the sides. Scutellum
moderate, transverse, broadly angulate behind. Elytra at base equal in widtli
to the prothorax, fully twice as long as the latter, three-fourths longer than
520 Coleopterological Notices, IV.
wide, the humeri very small, rectangular, feehly tumid, not prominent later-
ally ; sides very feebly convergent and just visibly arcuate from the base nearly
to the apex, then rather suddenly and semi-circularly rounded ; disk with
somewhat fine but deep grooves, the intervals flat, nearly three times as wide
as the strise, equal, each with a single series of minute but deep distinct
rounded and very remote punctures. Abdomen rather sparsely punctured.
Prosternum separating the moderately small coxse by fully their own width.
Lengtli 3.1-4.2 mm. ; width 1.15-1.5 mm.
Texas.
The type described above is a male and has a narrow elongate
and distinct, but not very deep, impression near the base of the
abdomen. The fifth ventral segment is broadly sinuato-truncate
and one-half longer than the fourth.
GLIPTOBARIS n. gen.
The single species forming the type of Glyptobaris possesses
many of the generic characters of Onychobaris, but differs in sculp-
ture and vestiture to a marlied degree and inhabits a different geo-
graphical region. It resembles Onychobaris in the structure of the
beak and antennae and especially in the remote anterior coxte and
broad flat prosternum, but differs distinctly in the form and extent
of the post-coxal parts of the prosternum, and also, somewhat, in
the structure of the mandibles. The latter are acute at apex and
come together along a crenulate line, but do not at all overlap in
repose ; they are straight in external outline, not at all arcuate, and
when closed form an isosceles triangle.
The broad prosternum has, anteriorly, two small deep foveie,
widely distant, arranged transversely, and connected by a very
narrow deep and abrupt groove; from each there extends poste-
riorly for a considerable distance a fine deep inwardly arci^ate
groove, the two being strongly convergent, the triangular space so
inclosed being flat and impunctate. Just behind the coxa?, before
the posterior margin of the broad prosternal process, there are two
distant strongly elevated transverse tubercles, of which no trace can
be seen in any species of Onychobaris, but which evince an unmis-
takable relationship with Madarellus as shown under that genus.
The pygidium is vertical and partially covered above by the over-
hanging tips of the elytra, somewhat as in Desmoglyptus.

head is not punctate but minutely g-ranulato-reticulate and dull, the
l)eak rather robust, very strongly arcuate and a little longer than
the prothorax, densely, coarseh^ punctured at the sides. The pro-
thorax is nearly one-third wider than long, with the sides evenly
and broadly rounded, becoming parallel near the base, the apex not
constricted but sometimes with a short prominent carina on the
sides at the apical margin, the base transverse and with a very
small but prominent median lobe, the disk coarsely, deeply, very
densely sculptured in longitudinal irregularly vermiculate rugse,
which are in some spots broken up into coarse punctures, and
having a fine, more or less prominent, subentire median carina.
Scutellum very small, ogival and not transverse. The elytra are
strongly narrowed from base to apex, three-fourths longer and but
slightly wider than the prothorax, the apex narrowly subtruncate,
the disk with rather fine but deep and abrupt, remotely crenulate
striae, the intervals flat, wide, finely sparsely and unevenly punc-
tate, the yellowish elongate scales forming a large quadrate spot in
basal three-fifths, the most prominent feature in the pattern being-
two transverse bands, each consisting of tw^o uneven lunules ; else-
where the vestiture is very sparse and inconspicuous. Length
3.6-4.3 mm. ; width 1.7-2.0 mm.
Somewhat abundant throughout the eastern and southern Atlantic
States. The specimens before me are from Indiana, Pennsylvania,
District of Columbia and North Carolina.
ONYCHOB4RIS.
LeCoute— Proc. Am. Phil. Soc , XV, p. 294.
The species of this genus are characterized in general by their
excessively densely punctured, rather dull integuments, although
there are numerous exceptions having the sculpture as sparse as in
Baris. Onychobaris is a widely distinct and somewhat extensive
genus, almost exclusively restricted to the desert regions of the
southwest, where it replaces Baris in great measure; at least one
species extends as far to the eastward as the Mississippi River and
another is known from the true Pacific fauna, but the focal centre
of the genus undoubtedly lies in the dry regions of Arizona and
New Mexico.
The vestiture consists of short robust semi-erect seta? as in Baris,
but is often so abundant, from the density of punctuation, as to
give to the surface a grayish-prninose a}>pearance. The generic
characters are stated at sufficient length in the table, and there are
522 Goleopterological Notices, IV.
hut few special peculiarities to which it is necessar\^ to call atten-
tion at present; one of these is, however, possibly of considerable
significance from an etiological point of view, and relates to the
modified impression of the prosternum. The prosternum is greatly
developed, rather remotely separating the coxae, and almost perfectly
Hat, but, in the middle, at some distance behind the anterior mar-
gin, there are two deep punctiform fovea?, moderately separated and
arranged transversely. These fovete are generall}^ connected by a
groove, and sometimes form the anterior limit of a more or less
visible but feeble short parallel-sided impression. A still more
advanced development of this peculiar modification of the remnant
of the rostral sulcus, has been described under the genus Glyptobaris.
In Onychobaris the beak is decidedly longer than in Baris, being
generally a little longer than the prothorax, and is always strongly
arcuate and more or less slender ; it is separated from the head
by a transverse impression, which is always feeble and invariably
al)ruptly impunctate and polished. The tarsi vary considerably in
structure, the last joint being frequently as long as the first three
together but generally shorter. The scutellum is transverse, never
impressed, and usually more or less broadly rounded behind. The
male sexual characters are feeble, the abdominal impression being
invariably slight and often scarcely distinguishable.
It is to be regretted that the majority of the species are still
represented by unique examples, and there is consequently reason
to believe that the following table contains only a small proportion
of the forms inhabiting the inhospitable and comparatively unex-
j»lored regions which have developed this interesting special type.

The series before me was collected by Mr. G. W. Dunn, at Saa
Diego, California, from which locality it was originally described.
Mr. H. C. Fall of Pomona, Cal., writes me that this si)ecies is
found at Coronado, immediately opposite San Diego on the line of
the seabeach, where it " frequents the flowers of a low Seshy-leaved
plant just above the beach." Mr. Fall states further that he has
" taken it in the flowers in July and in the sand beneath the plants
in February," and also remarks that in every specimen taken by
him "the legs, and beak to some extent, incline to paleness." It
may be concluded from these statements that derisa is confined in
distribution to the immediate seashore of Southern California.
2 OliycllOl>aris COrrosa n. sp. — Oblong-oval, convex, black, the head,

the transverse polished and impunctate interocular impression, whicli is
normally feeble ; beak thick, not sensibly tapering, rather strongly, evenly
arcuate, very densely punctate, the fine median impunctate line obliterated
toward base, equal in length to the prothorax ; antennae moderate, the second

moderately transverse, opaque. Elytra a little longer than wide, nearly four-
fifths longer than the prothorax, and, at the base, rather abruptly and quite
distinctly wider than the latter, the humeri but feebly tumid ; outline thence
around the apex hemi-elliptical ; di?k with moderately fine, not very deep but
abrupt striae, the intervals wide, fiat, alternating from two to three times as

fusedly punctate and strongly shining. Abdomen densely punctured toward
the sides and base, but sparsely so toward the middle of segments two to four.

A remarkably distinct species, to be known at once by the
coarsely, extremely densely sculptured and subopaque pronotum,
head and beak, and rather shining-, finely but unevenly punctured

the sTnal) and slightly prominent humeri, but little wider than the latter ;
sides distinctly convergent, the apex parabolic ; disk very finely striate, the
strife deep, abrupt, impunctate, the intervals flat, alternating slightly in
width, four or five times as wide as the strise, finely, deeply, closely and con-

punctate. Prosternum widely separating the coxse, the latter not quite as
small as usual. Length 4.7 mm. ; width 2.25 mm.
New Mexico ; Colorado.
The type is probably a male, the middle of the abdomen near the
base being very feebly impressed, and abruptly more coarsely and
very sparsely punctured.
This exceedingly isolated species may be known at once by its
very finely and densely punctured integuments, rather large size,
feebly rhomboidal form, large prothorax and short conical elytra.
As is frequently the case in this genus, the prothorax in some
specimens becomes feebly inflated, especially toward apex, a form
which is however constant and distinctive in some species.
5 Onychobaris aiistera n. sp. — Moderately robust, rhomboid-oval

densely punctate, the transverse impression feeble, indicated by a narrow
polished and abruptly impunctate line ; beak densely, rugosely punctate,
setulose, rather stout and broadly, evenly arcuate in basal half, becoming
straight and slightly tapering thence to the apex, very nearly as long as the
head and prothorax ; antennae inserted at the middle, moderately slender, the
basal joint of the funicle fully as long as the next three, second obconical, but
slightly longer than wide, three to seven transverse, club oval, pubescent,
with the basal joint large. Prothorax two-fifths wider than long, the sides
feebly but distinctly convergent and straight from the base to apical third,
then gradually, evenly rounded and convergent to the small but evident sub-
apical constriction, the apex transversely truncate and much less than one-
half as wide as the base, the latter transverse, the lobe constituting a little
more than one-third of the entire width, rounded and prominent ; disk very
deeply and densely punctate, without trace of impunctate line, the punctures
somewhat coarse. Scutellum moderate. Elytra at the small but prominent
humeral callus much wider than the prothorax, three-fourths longer than the
latter, a little longer than wide, broadly hemi-elliptical in outline ; disk with
distinct but not very deep striae, tlie intervals flat, slightly unequal, about
twice as wide as the grooves, coarsely, confusedly, closely and rugosely punc-
tured throughout but shining. Abdomen rather coarsely and deeply punctate,
the punctures well separatcid. Prosternum fla', the coxse very reniote.

California (San Die<ro). Mr. Ch Fuchs.
Allied to densa but differing radically in its black legs, much
smaller and still more dense pronotal punctures, without trace of
the median impunctate line usually quite distinct in that species,
and with much coarser and more conspicuous set®. It also resem-
bles depj-essa, but is much less depressed, as can be readily seen in
profile, and has the body more rhomboidal ; the subsquamiform setae
are not so coarse and are less dense.

subopaque, grayish-black throughout, the setse very short. Head finely,
closely punctate anteriorly, limited by a transverse impunctate line ; beak
very densely, finely but strongly punctate, with a fine dorsal impunctate line,
strongly arcuate, distinctly tapering from base to apex, very slightly longer
than the prothorax ; antennje slender, the second funicular joint longer than
wide and nearly one-half longer than the third. Prothorax about two-fifths
wider than long, nearly as in densa but with the punctures much smaller, fine,
deep, nearly in mutual contact but not polygonally compressed, rather more
than one third as wide as the scutellum. Scutellum small, transverse, not dis-
tinctly impressed. Elytra nearly one-fourth longer than wide, quite distinctly
less than twice as long as the prothorax, and, at the moderately prominent
humeri, slightly wider than the latter ; sides feebly convergent, the apex
semi-circular; disk with moderately coarse, deep, abrupt, irregularly punc-
tate striae, the intervals flat, alternating somewhat in width, the wider about
twice as wide as the grooves, all finely, densely, unevenly and subrugulosely
punctured. Abdomen shining, finely, not very strongly or densely punctured.
Prosternum flat, the coxfe rather small, separated by one-half more than their
own width. Length 2.3-3.3 mm. ; width 1.1-1. G mm.
Western Texas (Big Springs) — Mr. H. F. Wickham ; Southern

A rather small, e.xtremely densely and somewhat finely sculp-
tured, subopaque species, allied to densa, but differing in the much
finer punctures of the pronotum, smaller size and somewhat broader
form. Thirteen specimens.
7 Onycliobaris subtonsa Lee. — Proc. Am. Phil. Soc, XV, p. 295.
Oval, rather strongly convex and shining, black throughout, the
sette distinct. The beak in the female is strongly and almo.st evenly
arcuate, not distinctly tapering from base to apex and is slightly
longer than the prothorax, the second funicular joint one-half longer
than the third. The prothorax is barely one-fourth wider than
long, the sides very feebly convergent and almost straight nearly
to the apex, then strongly rounded and distinctly constricted, the

punctures small, deep, circular, scarcely one-third as wide as the
seutellum and not quite in actual contact, although very dense.
The elytra are quite distinctly longer than wide, fully two-thirds
longer than the prothorax, and the sides behind the humeri are
decidedly convergent, the apex being somewhat narrowly semi-
circular ; the striiie are not very coarse or deep but abrupt, the
intervals flat, subequal in width, each rather more than twice as
wide as the grooves and not very coarsely punctured, the punctures
forming almost even single rows, but broadly confused on the fifth
throughout and on all toward base. The anterior coxce are remote
and the abdomen rather sparsely punctured. Length 2.C-3.S mm.;
width 1.2-l.C) mm.
Texas, Kansas and Colorado. Easily distinguishable from the
species allied to densa, by the subserial arrangement of the inter-
stitial punctures and the more elongate form.

coarsely but rugosely punctate and quite distinctly shorter than the prothorax ;
antennae rather slender, inserted just behind the middle, the first funicular
joint fully as long as the next tliree, the second obconical, one-half longer ihan
wide, three to seven feebly transverse, the former nearly as long as wide.

apical fourth, then rather abruptly, strongly rounded, thence convergent and
feebly sinuate to the apex ; base transverse, broadly bisinuate ; disk rather
convex, evenly, closely, not finely punctate, the punctures rounded, deep,
about two-fifths as wide as the seutellum and generally separated by about
one-half of their own diameters ; impunctate line obsolete. Seutellum rather
small. Eljjtra slightly wider than the prothorax and from one-half to three-
fifths longer, distinctly longer than wide, hemi-elliptioal, the humeri mode-
rately prominent ; strije not very coarse, somewhat shallow but abrupt, the
intervals slightly unequal, generally nearly twice as wide as the grooves, flat,
smooth, each with a single series of deep punctures which are moderately
large and rather distant, but becoming coarse and close-set toward base.
Abdomen rather finely but strongly punctate. Prosternum flat, the anterior
coxse rather large, separated by one-fourth more than their own width. Length
2.65-2.8 mm. ; width 1.2-1.3 mm.
California (foot-hills of the southern sierras). Mr. 11. C. Fall.
This species is not closely related to any other but should be
associated with audax ; it differs from ambigua and egena in its
black legs and in several other characters as stated in the table. In
general form it somewhat resembles pavperella.

than tiie disk of the latter ; sides for a short distance behind the humeri
parallel, then elliptically rounded through the apex ; disk with rather nar-
row, deep and finely, remotely but distinctly punctate grooves, the intervals

confused toward base especially on the fifth. Abdomen rather finely, not densely
punctured. Length 3.0 mm. ; width 1.4 mm.
California (southern).
A small and easily recognizable species, having the prothorax
rather wider at apical fourth than at base, and with the sides straight.
It is also somewhat aberrant in coloration.

Arizona (Benson). Mr. G. W. Dunn.
Somewhat similar to svblonsa in general outline, but in scarcely
any other character. The seta^ of the elytra in subtonsa are very
small, subrecumbent and not conspicuous, while in utictica they are
unusually long, erect and form even bristling single series on each
interval ; the indistinct punctures of the grooves also bear smaller
setae which are, however, visible under moderate power. The
punctures of the pronotum are a little less dense along the middle.

sides ; base subtransverse, the median lobe large, rather more than one-third
the total width, prominent, broadly rounded ; disk without trace of median

wider than the latter ; outline behind the humeri broadly hemi-elliptical ;
disk with abrupt deep coarse and confusedly punctured grooves, the intervals
flat, narrow, subequal, exactly equal in width to the grooves and each with a

longer than wide, third to seventh increasing in width, the former nearly as
long as wide, the latter strongly transverse, club rather small and narrow, not
abrupt. Prothorax one-fourth wiiier than long, the sides straight and just
visibly divergent from the base to apical third, then broadly rounded to the
small but distinct constriction ; apex very briefly tubulate, truncate and dis-
tinctly more than one-half as wide as the Itase, the latter rather deeply bi-
sinnate ; disk without trace of impunctate line, deeply, rather coarsely and

Arizona (Pinal Mts.). Mr. H. F. Wickham.
A small species belonging to a group in which the species become
rather closely allied. It perhaps approaches jjauperella more nearly
than any other form here noted, but differs in its shorter elytra,
with smaller and less conspicuous sette and much coarser more
close-set interstitial punctures, and also in the coarser punctures of
the head and pronotum. From o.mbigua it differs in its smaller
size, narrower form, much shorter, less visible setae and narrower,
more coarsely, closely and evenly punctured intervals.

Arizona.
A somewhat small species, closely allied to pauperella, but easily
distinguishable by its larger size and more robust form, also by its
shorter elytra, not only actually but relatively to the prothorax ;
the sides of the latter are parallel in basal three-fourths in this
species, but feebly convergent toward base in basal two-thirds in
pavpei^ella, the widest part of the disk in the latter being at apical
third. The prothorax is longer in amhigua, and the elytral inter-
vals wider. It is represented by four specimens, one of which is
contained in the collection of the National Museum, and was prob-
ably collected by Mr. Morrison.

moderately long, distinct and forming rather conspicuous single series on the
elytra. Head finely, rather sparsely punctate toward apex, the beak densely
punctured at the sides, rather thick, equal in length to the prothorax, feebly
tapering from base to apex, evenly and strongly arcuate ; antennje moderate,
the second funicular joint but slightly longer than the third. Prothorax nearly
one-third wider than long, the sides feebly divergent and nearly straight to
apical third, then gradually broadly rounded and convergent to the apex,

actual contact. Scutellum moderate, ^/^ira about one-fifth longer than wide,
one-half longer than the prothorax, and, at the rather small but somewhat
prominent humeri, quite distinctly wider than the latter ; outline behind the
humeri hemi-elliptical, the sides distinctly convergent : disk coarsely, deeply
striate, the intervals sometimes feebly alternating in width, slightly, to fully
one-half, wider than the grooves, each with a single somewhat uneven series
of coarse, deep, close-set and subrugulose punctures. Abdomen moderately
closely punctured. Prosternum separating the rather large coxse by one-fourth

The smallest species of the genus and very distinct from an}'
other which I have observed. It is unusually narrow and parallel,
moderately convex, black and polished, the beak rather robust,
moderately and evenly arcuate and slightly longer than the protho-
rax, the antennae normal in structure, the basal joint of the funicle
not as long as the next four and the second but very slightly longer
than the third. The prothorax is nearly as long as wide, parallel
on the sides to apical fourth, then broadly rounded and convergent
to the apex, which does not appear to be at all constricted; there is
but feeble trace of a short median line and the punctures are deep,
about one-third as wide as the scutellum and separated by nearly
their own widths toward base, but nearly contiguous toward apex.
The elytra are much longer than WMde and about two-thirds longer
than the prothorax, finely but deeply and abruptly striate, the inter-
vals flat, subequal, about three times as wide as the grooves and
each with a single series of very minute distant punctures, each
bearing a scarcely distinguishable seta ; the striae become quite
coarsely crenulate very near the base. Length 2.3 mm. ; width
0.8 mm.

scutellum, slightly smaller near the median line. Scutellum moderate, trans-
verse. Elijtra parabolic behind the humeri, quite distinctly longer than wide,
one-half longer than the prothorax, and, at the small and feebly prominent
humeri, but slightly wider than the latter ; disk not very coarsely but deeply
and abruptly striate, the intervals subequal, fiat, about one-half wider than
the grooves, each with a single series of rather coarse, subtransverse and dis-
tant punctures. Abdomen not very densely punctured. Length 3.7 mm. ;
width 1.7 mm.
Texas (El Paso).
The type appears to be a male, the abdomen being very feebly
flattened and more sparsely punctured in the middle near the base,
while the type of dutans is apparently a female ; but the two forms
differ so greatl}^ in bodily form and otherwise, that I regret to
believe there is but little doubt of their mutual distinctness.
Remota diff'ers from distans, irrespective of the shorter beak which
may possibly be a sexual character, in its more elongate-oval form,
in its much less transverse, more coarsely and pronouncedly more
densely punctured prothorax, with narrower median line, and in its
longer and more coarsely striate elytra.

the median line. Elytra parabolic, but slightly longer than wide,
one-half longer and just visibly wider than the prothorax, not very
coarsely but deeply and abruptly striate, the intervals flat, subequal,
more than twice as wide as the stride, each with a single series of

The single specimen before me represents a species rather closely
allied to molesta, differing in its more slender form and in the much
finer, sparser and transverse punctuation of the elytra, also very
noticeably in its much larger pygidium, the types of both of these
species being females.

MADARELl,US n. gen.
A series of Conoprodus quad ripust ulatus Fab. (quadriplagiatus
Lac), taken by Mr. H. H. Smith on the Amazon near Santarem,
shows clearly that Lacordaire's type of Conoproctus is the male.
In the female the form, sculpture and coloration throughout are
similar, but the beak is not so long, more arcuate and tapering, with
the antennfe shorter and inserted near the middle, the pygidium
being broadly rounded, oblique and perfectly normal. These sexual
differences are extraordinary, but are evinced in an unmistakably
parallel and, as far as the beak is concerned, almost equally striking
manner in another Brazilian species, from the same collection and
not yet identified, but which, from its general habitus and simple
male pygidium, must be assigned to Madarus. Finally, in Madams
hiplagiatus, which I also have liefore me, the same sexual differences
are observable but to a very slight degree, the antennte being in-
serted near apical third in the male and just bej'ond the middle in
the somewhat shorter beak of the female; quadripustulatus is how-
ever the only species in which the pygidium is affected sexually.
It is quite evident, therefore, that hiplagiatus and quadripuslu-
latus must be placed in the same genus, and I would suggest that
these species be included under the name Conoproctus Lac, and
that the name Madarus Sch. be reserved for those species mentioned
by Lacordaire (Gen. Col., VJI, p. 257), as forming a second section
of Madarus, and having as types vortivosus and migrator. Both
Conoproctus and Madarus, as thus limited, have the femora un-
armed, and I have here proposed the genus Madarellus, to include
those species having the prothorax short, broad, very abruptly
and strongly constricted at apex, and the femora armed beneath
with a minute spiculiform denticle. It differs further from Cono-
proctus in having the posterior lobe of the prosternum broadly
eniarginate or subtransverse, with the lateral angles acute and not
broadly rounded as in that genus, in having a post-apical prosternal
fovea with short parallel folds of the surface, and a small triangular
scutellum, truncate at base and not large, short and broadly lunate
as in Conoproctus. The anterior coxfe, it should be added, are
much more remote and rather smaller than in the latter genus.
In Madarellus the beak is about one-half as long as the body in
the female, evenly, distinctlv arcuate, slender, the impression sepa-
rating it from the head being almost completely obsolete and the
Goleopterological Notices, IV. 541
epistomal lobe not at all advanced, very broad with the lateral fissures
extremely small, the mandibles well developed, each with two deep
notches at apex, feebly arcuate and not overlapping when closed but
forming a small triangle. Antenna^, normal, the first funicular joint
as long as the next four, the second but slightly longer than th<!
third, the club moderate, pubescent, scarcely longer than the four
preceding joints combined and with the basal joint constituting less
than one half the mass.
The prosternum is very large, flat, thrown up in a transverse
tumid ridge just behind the coxjb, in the position of the two trans-
verse tubercles of Glyptobaris,' the ridge strongly declivous behind
and produced over the mesosternum, terminating on a line drawn
through the middle of the intermediate coxae, the process very wide,
acutely angulate at the sides and broadly sinuate between the angles.
At a short distance behind the anterior margin there are two deep
angulate more or less coalescent foveas, each continued posteriorly
for a short distance by a fine but distinct fold of the surface. Ante-
rior coxfe small, very remote, separated by fully twice their own
width. Legs moderate, the tarsi normal, with the third joint broad,
bilobed; claws moderate, perfectly free, somewhat divergent. Scu-
tellum small, triangular or ogival, not in the least emarginate at base.
That two genera, mutually so dissimilar in appearance as Mada-
rellus and Glyptobaris, should in reality be so closely allied, is one
of these interesting surprises continually offering themselves in these
little-studied groups. I am quite unable to agree with LeConte in
his statement that Ampeloglypter makes a gradual transition from
J3aris to Madarellus, for the latter is much more closely allied to
Baris through Onychobaris than is Ampeloglypter, this genus
forming one of the pseudobaride series; but, at the same time, the
position assigned to Madarus by Lacordaire seems to be equally
unnatural.

This species is so well known, that a detailed description is need-
less at the present time. The form is subcuneate, rather wider at
the middle of the prothorax than at any other part, the thoracic
punctures extremely minute, feeble and sparse, but becoming rather
closer, stronger and feebly rugulose or subasperate anteriorly, rugu-

lose at the sides, and with an even series of small but deep punctures
just before the basal margin not quite extending to the scutellum.
The elytral stritB are in the form of narrow but deep abrupt grooves,
minutely, and distantly punctate at the bottom, the intervals flat,
wide, each with a single series of excessively minute distant punc-
tures, except the lateral three, where the punctures become distinct
but feeble, not very dense, confused and transversely rugulose or
subasperate. The lustre throughout is highly polished, and the
color black, the prothorax being often entirely red, but I do not
notice that this character is at all geographical in origin as stated
by LeConte (Proc. Am. Phil. Soc, XY, p. 301), a good series
before me from Indiana being composed of both color modifications
in equal numbers. It varies greatly in size. Length 2.7-4.7 mm ;
width 1.3-2.2 mm.
Entire Atlantic region, extending westward to Kansas and Texas,
The anterior femora are armed beneath with a small tooth, which
is rendered more prominent by reason of a deep and abrupt sub-
apical emargination immediately beyond it. The intermediate and
posterior femora are not distinctly denticulate in undulatus, but in
an entirely similar, but shorter and broader species before me, from
Santarem, Brazil, all the femora are distinctly spiculate beneath.
The pygidium in this genus is distinctly oblique in the male but
vertical in the female, which corresponds somewhat with the pygi-
dial differences of the male and female in Conop7-octus quadripus-
tulalas.
AULOBARIS.
LeConte— Proc. Am. Phil. Soc, XV, p. 288.
This genus is one of the most distinct of the tribe, and is remark-
ably homogeneous in the general aspect of its species, which are
unusually convex, polished and, with the exception of dux, almost
evenly ellipsoidal in form.
Aulobaris diflfers from all of our other genera of pygidiate Barini,
in having the second funicular joint elongate and fully as long as
the next two combined. In its free and divergent tarsal claws it
resembles Baris, but in spite of this_there is a certain assemblage
of characters which suggests a rather closer relationship with Pseu-
dobaris. In fact Aulobaris pusilla was originally described as a
Pseudobaris, and Pseudoharis anthracina (Lee. nee Boh.) as an
Aulobaris, showing how closely they approach each other in external
Coleopterological Notices, IV. 543
faciefj. But in addition to this they are allied in the deep sulcus
of the presternum common to both; it is however rather less ab-
ruptly defined at the edges in the present genus, and besides differs
radicall}^ in serving as a partial shelter for the beak in repose.
In A. naso the sulcus is broadly sinuate at the sides, the latter
projecting inward just before the cox:k, touching the middle of the
beak when the latter is folded in against the body. These projec-
tions of the sides before the coxce, although not very })rominent,
are extremely interesting as being the nearest approach to similar
modifications of the sides of the rostral sulcus observable in many
cr3'ptorhynchs. Aulobaris in fact possesses several suggestive
cryptorhynchine characteristics. It is interesting in this con-
nection to call attention to the close general similarity of certain
barides, as Eisonyx and Aulobaris, to such cr3'ptorhynchs as Bar-
opsis and Tyloderma.
The remaining characters of Aulobaris are not of especially deci-
sive value, but it should be mentioned that the third tarsal joint is
unusually wide and deeply bilobed, and that the prosternum is pro-
longed behind slightly over the mesosternum, the process being wide
flat and broadly arcuate at apex. In Madarellus it is still further
prolonged upon the mesosternum and is broadly sinuate or sub-
truncate throughout its width. In all of our species there is a small
cluster of squamules at the base of the third elytral interval, as in
many species of Pseudobaris.
In A. scolopax the sexual characters are very pronounced, the
abdomen in the female being strongly conical and upwardly ascend-
ing toward apex, with the pygidium small. In the male it is nearly
horizontal, with the pygidium much larger. These pygidial differ-
ences are of the same general order as in Baris. In the female of
scolopax the prothorax is much shorter than in the male, as in
Centrinus scutellum-album.
The species are not numerous and may be separated as follows : —
Prothorax feebly transverse and miicli narrower than the elytra, moderately
convex, with the basal lobe rather prominent.
Prosternal sulcus sinuate at the sides and produced inwardly near the
coxse ; elytral punctures coarse, deep and rounded 1 iiaso
Prosternal sulcus straight at the sides, without the ante-coxal projection ;
elytral punctures small, feebly impressed and slightly transverse.

Ellipsoidal, strongly convex, polished and piceous-black through-
out, the sette very minute on the upper surface, with a few squani-
ules at the base of the third interval, each puncture of the under
surface bearing an elongate recumbent strigose scale. Head finely
but distinctly punctate, the transverse impression feeble and finely
subfoveolate in the middle ; beak rather slender, strongly, evenly
arcuate and as long as the head and prothorax, the antnneae slender,
first funicular joint long, the second more than twice as long as wide,
two-thirds as long as the first and equal to the next two, third a
little longer than Avide, outer joints but slightly wider, club oval,
densely pubescent, equal in length to the preceding five joints com-
bined, the basal joint constituting much less than one-half the mass.
Prothorax conical, strongly convex, one-third wider than long, with
the sides broadly and evenly arcuate and only very feebly constricted
near the apex, which is transversely truncate and not quite one-half
as wide as the base; punctures small but deep and distinctly sepa-
rated. Scutellum moderate, transverse. The elytra are slightly
longer than wide, two-thirds longer and scarcely perceptibly wider
than the prothorax, hemi-elliptical in outline, the humeral tuberosi-
ties very feeble, the striae rather coarse and deep, with the intervals
about twice as wide as the grooves, and each with a single series
of large deep rounded and somewhat close-set punctures. Length
2.8-3.3 mm. ; width 1.3-1.6 mm.
The four specimens in my cabinet are from Kansas and Iowa, and
the reference of certain Californian specimens to this species by Dr.
LeConte is apparently incorrect, these being identical with jiusilla.
The reference to nasntus (1. c. ante) is somewhat confusing. Le-
Conte refers to Say's Cure, Ed. Lee, I, p 295, but this reference
was probably intended to be Proc. Ac. Nat. Sci., Phila., 1868, p.
364, where the author has described this species under that name,
forgetting that he had already described a Centrinus nasutus. As
Centrinus and Aulobaris are widely different genera, there w^as no
necessity for the change of name, but since they are both proposed
Coleopterological Notices, IV. 545
by the same author, and as naso is the name adopted in the most
extensive monograph of our Rhynchophora, it is preferable to con-
tinue it.
The prosternal groove is very large deep and abrupt, serving as
a partial shelter for the beak, which, in repose, is placed in the groove
with its apex extending far beyond it and resting on the flat surface
of the mesosternuni. The strong arcuation of the beak prevents it
from touching the bottom of the groove however, and, at the sides,
it is in contact only just before the coxte, where there is an internal
horizontal projection, not distinctly observable in any other species.
2 Atllobaris piisilla Lee— Proc. Ac. Nat. Sci., Phila., 1SG8, p. 363
(Baridius) ; Proc. Am. Phil. Soc, XV, p. 298 (Pseiidobaris).
Almost exactly similar throughout to nano, but rather shorter,
relatively stouter, and with the interstitial punctures smaller, much
feebler, close-set and subtransverse. The second funicular joint is
fully three-fourths as long as the first and as long as the next two,
the club small and not longer than the four preceding joints together.
The prosternal sulcus is as wide and deep as in naso, but the sides
are straight and not broadly sinuate, there being no visible trace of
the internal projection just before the coxsb referred to under that
species. Length 2.5-3.0 mm.; width 1.1-1.4 mm.
I have seen specimens from New York, District of Columbia,
North Carolina and one labeled " California." Dr. LeConte evi-
dently limited his attention to the prosternal sulcus only, in placing
this species in Pseudobaris.
3 Aulobaris SCOlopax Say — Cure. 26, Ed. Lee, I, p. 295 (Baridius).
Similar in form, and in antennal and prosternal structure to
pusilla, but distinctly larger, pale red-brown in color, the elytral
striae finer, the intervals wider, the punctures broadly confused on
the second and third but forming single lines on the others, small,
feeble, moderately close-set and slightly transverse. The punctua-
tion of the pronotum varies greatly, being sometimes decidedly
coarse and at others quite fine; the punctures also vary in density,
although usually distinctly separated, and there is a narrow incom-
plete impunctate line, which occasionally entirely disappears, as
remarked by LeConte. This latter fact is however characteristic of
the entire tribe, when the impunctate line is not especially broad and
decided or cariniform. Length 3.3-3.1 mm.; width 1.65-1.8 mm.

equal and quadrate; club very small, oval, abrupt, subequal in
length to the three preceding joints combined. Prothorax two-fifihs

AIWPELOGLYPTER.
LeConte— Proc. Am. Phil. Soc, XV, p. 299.
A distinct genus, evidently composite in its characters and form-
ing one of the transitions from Madarellus to Pseudobaris, but, in
spite of the polished glabrous integuments and finely striate, im-
pressed and subimpunctate elytra, which give it an external resem-
blance to the former, it is in realty much more closely allied to the
latter of these genera.
The prosternal modification is peculiar to this genus, although
feebly suggested in some other forms such as Glyptobaris. In
sesostris \i is widely and rather feebly impressed, the impression be-
coming flat and obsolete between the cox!X3, subimpunctate through-
out, widening slightly anteriorly, and ending near the apical margin,
at the transverse prothoracic constriction. At its anterior limit it
is deepest, and is bounded by an abrupt declivous wall which is
transverse and nearly straight; the sides of the excavation are also
abrupt for a short distance behind the apex. In longipennis it is
rather wider and more feeble, but deep and abruptly limited at each
apical angle. It is easy to perceive here an extreme development
of the two deep foveae and connecting groove mentioned under
Onychobaris and its allies, only here the two angles of the impres-
sion, which represent the fovete, are relatively much more widely
separated.
The anterior coxfe are small, rather distant and separated by more
than their own width. The beak and antennte present no notice-
able peculiarities, being nearly as in Pseudobaris. The claws are
moderately long, closely connate in basal third, subparallel and
gradually, feebly everted toward tip as in the pseudobarides gener-
ally, and diff"ering radically from the normally free and divergent
form seen in Madarellus.
Our three species may be readily distinguished as follows : —

ture of the prothorax, beak and antennse, but is larger, still more
highly polished especially toward the sides of the upper surface,
intense black in color and with relatively longer elytra, the protho-
rax, also, is shorter and broader, with the sides more rapidly con-
vergent from the base, and the tubulate apical portion is shorter,
less abrupt and much narrower when compared with the l)asal
width. The pronotum is more finely punctate and devoid of im-
punctate line, but .occasionally has a small impressed fovea at the
centre of the disk. The two specimens from Maryland have the
elytra dark castaneous but do not otherwise differ. Sixteen exam-
ples. Lovgipennis is generally confounded in cabinets with cder.

Rather narrowly oval, moderately convex, polished, pale red-
brown throughout, the seta3 extremely minute. Head dull, obso-
letely punctulate; beak shining, rather slender and one-half longer
than the prothorax in the female, feebly arcuate, abruptly more
strongly so at base, the transverse impression rather strong; an-
tennae inserted just behind the middle, the funicle rather slender,

club oval, pointed, densely pubescent and as long- as the preceding-
five joints, with its basal joint constituting two-fifths of the mass.
The prothorax is feebly narrowed and straight at the sides to apical
third, then broadly rounded, more convergent and deeply sinuate to
the apex, the latter subtubulate and three-fifths as wide as the base;
disk finely but rather sparsely, distinctly and unevenly punctate,
Avith a subentire impunctate line. Elytra one-fourth longer than
wide, a little wider than the prothorax and not distinctly more than
twice as long as the latter, striate and subimpunctate as in ater.
Under surface, except along the middle of the abdomen, and also
the legs throughout deeply, densely punctate and opaque. Length
2. "7 mm.; width 1.2 mm.
The two specimens in my cabinet are from Illinois, and are not
as large as the type measured by LeConte (3.0 mm.).
DESMOGLYPTUS n. gen.
This genus is closely allied to Pseudobaris and has the prostcrnum
deeply and abruptlv sulcate throughout its length, the anterior coxa^
being somewhat remote and separated by fully their own width.
The beak, antenna?, tarsal claws and scutellum are also nearly as
in Pseudobaris, but the other characters are so different that the
unique species cannot be appropriately associated with the mem-
bers of that genus.
The general appearance and elytral sculpture are essentially un-
like anything else in the present tribe which I have been able to
study, but it is possible that the Baridius crihratus of Boheman
may be somewiiat similar, or perhaps even congeneric. The form
of the body reminds us strongly of Copturus, and the opaque sur-
face, deep impressed and strongly crenulate strioe, with narrow and
convex intervals, together with the unusually prominent subapical
unibones, are a combination of characters apparently isolating the
genus widely from its allies. It should be stated, however, that
the peculiar outline is feebly suggested in Pseudoharia angusta.
Desmoglyptus differs from Pseudobaris radically, also, in the for-
mation of the pygidium and elytral apices, the latter being deeply
and vertically truncate or deflexed, covering a large part of the
pygidium, which is small, vertical and flat. In Pseudobaris the
pygidium is large, convex and prominent, the el3^tra being normal
at apex and leaving it conipletel}' exposed. In Desmoglyptus the
third tarsal joint is abruptly very large, but not quite as wide as
Coleopfei'ological Notices, IV. 551
long, the emargination being unusually deep; the basal node of the;
fourth joint is distinct and a little longer than wide.
The single species is described below; it has comparatively little
affinity with Ampeloglypter, where it was provisionally placed by
LeConte.
1 Desmoglyptus creiiatus Lee. — I'roc Am. Phil. Soc, XV, p. 300
( Aiupf loglypter) .
Very narrow, subcylindrical, pale red-brown throughout and
densely opaque, the setae not distinct. Head rather convex,
minutely, obsoletely punctate, the beak ecjual in length to the
prothorax in the male, robust, strongly, evenly arcuate, feebly flat-
tened toward apex, obsoletely punctate, the antennte inserted well
beyond the middle, normal in structure, the first funicular joint as
long as the next three, two to seven equal in length, the outer
gradually slightly wider, the club oval, about as long as the pre-
ceding five joints together, pubescent, with the basal joint constitut-
ing much less than one-half the mass. Prothorax nearly as long
as wide, the apex broadly subtubulate, the sides parallel and straight
in basal two-thirds; apical margin feebly arcuate and three-fourths
as wide as the base ; disk without impunctate line, the punctures
rather coarse, deep and dense. Scutellum small, rounded. El3^tra
three-fourths longer than wide, a little wider than the prothorax
and about twice as long as the latter, the humeri slightly promi-
nent; sides parallel in basal three-fifths, broadly sinuate behind the
humeri, the apex narrowly subtruncate; disk of each strongly um-
bonate or callous in the middle near apical fourth, the striae coarse
deep and impressed, remotely but strongly crenate, the intervals
narrow, convex, each with a single series of remote minute and
excessively feeble punctures, which are scarcely at all observable
under moderate power. Abdomen not densely punctate, with a
very large broad and deep basal impression in the male; in this
sex the thickened posterior edge of the fifth segment is deeply,
transversely excavated opposite the apex of the pygidium, and
from the bottom of this excavation there projects a small, short and
transverse polished tubercle. Length 2.7-8.0 mm.; width 1.0 mm.
The two specimens before me are males and one of them is
labeled "Arizona." LeConte gives Virginia and Maryland as the
habitat of his types.

PSEVDOBARIS.
LeConte— Proc. Am. Pliil. Soc, XV, p. 297.
In geographical distribution this distinct genus coincides with
Baris and is well represented in Brazil. The species within our
territories are much less numerous than those of Baris, and are
usually of a narrower and more cylindrically convex form. Some,
however, are robust, but are then more oval and ellipsoidal and less
oblong than in the genus referred to. The generic characters have
been given in the table and need not be repeated at the present time.
One of the most striking peculiarities of the genus is the deep,
abrupt, parallel-sided and subimpunctate prosternal sulcus. The
fact that the sulcus should be so well developed and abruptly defined
at the sides in most of the species, when it can fulfill no function as
a shelter for the beak, because of the robust form and much greater
lateral dimensions of the latter, might be regarded as a proof that
the Barini are simply cryptorhynchs which have become modified
through changed habits or some other altered environment, and,
that under their influence, the beak and mesosternal epimera have
become modified with comparative rapidity. The prosternal sulcus,
being a long established and extremely permanent structure, would
survive in an essentially unaltered state for a long period after all
need of it had disappeared.
The species known to me may be distinguished by the following
characters : —
Elytral vestiture uniform, generally short and sparse.
Elytra with a small condensed pubescent spot at the base of the third
interval.
Pronotal punctures sparse, the impunctate line obsolete.
Large species, robust, piceo-testaceous in color 1 farcta
Moderate in size, rather robust, black throughout, polished, without
trace of aeneous lustre, the pronotal punctures and elytral striae
coarse and deep ; intervals not carinate toward apex.. .2 llictliosa
Pronotal punctures much closer.
Body elongate-oval, rather alutaceous in lustre, median impunctate
line of the pronotum narrow and distinct but not quite entire.
3 discreta
Body broadly oblong-oval, highly polished, the median line obsolete.
4 fausta
Elytra without basal condensed spot on the third interval.
Form more broadly oval ; interstitial punctures large, deep, rounded and
conspicuous, esi^ecially toward base.
Coleopterological Notices, IV. 553
Larger species, very broadly oval and subdepressed, dull in lustre;
elytral grooves coarse, the set?e very minute 5 pectoralis
Smaller, more elongate-oval, highly polished, the elytral strise much
less coarse, the setie longer, semi-erect and quite conspicuous.
6 liigubris
Form slender, cylindrical, the interstitial punctures small, feel)le, remote
and transversely subrugulose 7 aiiglista
Elytral vestiture consisting of very small inconspicuous seta; and long wiiitH
widely dispersed squamules.
Larger species, with the pronotal punctures moderate in size, very dense
and with a more or less distinct and abruptly defined median impnnctate
line S iiigrina
Small species, with the pronotal punctures coarse and slightly separated,
without trace of median impunctate line 9 c£Blata
The Mexican acutipennis of Say also belongs to this genus, and
has the elytral intervals prominent and subcarinate on the posterior
declivity, as in several other species of the Central American regions.

(Baridius) ; Proc. Am. Phil. Soc, XV, p. 297.
A conspicuous species, the largest of the genus, of a broadly
evenly oval, very convex form, dark piceo-rufous color and polished
integuments. The beak is evenly but rather feebly arcuate, robust,
becoming rapidly thin and flattened near the apex, slightly shorter
in the male than in the female, and, in both sexes, distinctly shorter
than the prothorax ; the antennte are normal, with the second funi-
cular joint one-half longer than the third. The prothorax is nearly
one-half wider than long, the sides convergent and broadly arcuate
from base to apex, broadly and distinctly constricted near the latter,
the constriction being evident and more densely, rugosely punctate
almost entirely across the dorsal surface ; base transverse, the median
lobe small but very prominent; the disk is coarsely but not very
densely punctate, without impunctate line. Elytra quite distinctly
wider, and fully three-fourths longer than the prothorax, hemi-
elliptical, the disk with rather coarse deep and abrupt grooves, the
intervals flat, scarcely twice as wide as the grooves, the second and
third much wider, the punctures rather large, moderately deep, not
very close-set and distinctly transverse, forming single series on
each, but sparsely confused on the second and third. The anterior
coxfe are separated by their own width, the prosternum before them
narrowly deeply and abruptly sulcate. Length 4.7-5.0 mm.; width
2.4-2.6 mm.

'1 PseildObaris llictuosa n. sp. — Rather broadly, almost evenly
oval, strongly convex, intense black and highly polished throughout. Head
minutely, sparsely punctate, the transverse impression rather strong ; beak
densely punctate only on tiie sides behind the antennae, somewhat tumid above
at base, strongly, evenly arcuate, slender and nearly one-third longer than
the prothorax in the female, rather thicker and but very slightly longer than
the latter in the male; antennae moderate, the second funicular joint unusu-
ally long and subequal to the next two together. Piothoiax short, nearly one-
lialf wider than long, the sides broadly arcuate and convergent anteriorly,
gradually becoming parallel toward base, the apex broad, truncate, tubularly
but very briefly produced ; base transverse and straight laterally, the median
lobe one-third the total width, rounded and decidedly prominent ; disk strongly
convex, coarsely, very deeply and rather sparsely punctate, the punctures
fully one-half as wide as the scutellum and separated by their own widths or
more. Scutellum small, transverse, impressed. Elytra twice as long as the
prothorax, and, at the feebly tumid humeri, scarcely perceptibly wider than
the latter ; outline hemi-elliptical ; disk with coarse, very deep, not distinctly
punctate grooves, the intervals subequal, about one-third wider than the
grooves, each with a single series of shallow, rather remote and transversely
subrugulose punctures ; setae not at all visible except a small spot of white
squamnles at the base of the third interval. Under surface somewhat sparsely
punctured. Length 3.5-3.7 mm. ; width 1.7-1.8 mm.
Florida (Cedar Keys).
This species is named anthracina Boh. in many cabinets, and
was placed in Aulobaris by LeConte (Proc. Am. Phil. Soc, XY, p.
289), but is evidently not the species described under that name in
the work of Schonherr. The phrases " thorax postice longitudine
fere latior," for a strongly transverse prothorax, and " [thorax]
supra fere planus . . . evidenter crebre . . . punctatus," for a strongly
convex, coarsely and sparselv punctate modification of this part,
and "elytra . . . thoracis . . . dimidio longiora," for fullv twice as
long, will not at all answer for this insect. As no allusion to a
pygidium is made in the original description, it is possible that
Baridius anthracinus Boh. may be a species of the genus Limno-
baris, but we shall probably never know definitely until the type
can be consulted.
3 Pseildobaris discreta n. sp. — Elongate-oval, strongly convex, black
throughout and rather shining, the prothorax duller and alutaceous ; setae
small, subrecumbent sparse but quite visible, not intermixed with longer
squamules but larger and coarser and forming a more or less distinct spot at
the base of the third and fifth intervals. Head and base of the beak opaque
and densely granulato-reticulate, the former minutely and obsoletely punctate,

where shining and almost inipiinctate, the transverse impression feeble and not
at all shining ; beak slender, rather feebly but ev-enly arcuate, somewhat ab-
ruptly thicker very near the base in the densely punctured part, distinctly
longer than the prothorax ; antennae slender, the second funicular joint nearly
twice as long as wide and one-half longer than the third, the latter a little
longer than wide. Prothorax barely one-fifth wider than long, the sides sub-
parallel in basal two-thirds, then strongly rounded and convergent to the apex,
the later strongly constricted and subtubulate ; base transverse, the median

each with a more or less uneven single series of moderately large but shallow,
sul)transverse, somewhat close-set punctures. Abdomen i-ather closely punc-
tured. Prosternura abruptly, deeply sulcate, the sulcus extending deeply
nearly to the posterior limits of the coxfe, the latter separated by about their
own width. Length 4.0 mm. ; width 1.7 mm.

4 Pseudoliaris faiista n. sp. — Oblong-oval, convex, black and highly
polished throughout, the setaj small, very sparse, not conspicuous, the elytra
without dispersed squamules but with a small feebly condensed spot at the

feebly tapering, deeply, densely punctate and about as long as the prothorax ;
antennje inserted at the middle, the basal joint of the funicle not quite as long
as the next three, the second obconical, one-half longer than wide, club rather
large, abrupt, densely pubescent, with the basal joint constituting one-third of

gent, the subapical constriction very broad and feeble ; base transverse, the
median lohe moderate in width, very prominent and rounded ; disk rather
coarsely, very deeply, moderately closely punctate, without impunctate line,
the punctures rather uneven in distribution, fully one-third as wide as the

Arizona.
Lugubris is the only species with which the present can be com-
pared, but there are many radical points of difference. \n fausta
the form of the body is much broader, and the punctuation through-
out very much coarser, with but the feeblest trace of a narrow and
partial impunctate line on the pronotum. The prosternal groove is
rather narrow, much deeper and more sharply defined in lugubris,
and, in the latter, there is no condensed spot at the base of the third
interval.
5 Pseudobaris pectoralis Lee. — Proc. Am. Phil. Soc, XV, p. 420.
Rather broadly oval and quite distinctly depressed, black through-
out, dull and strongly alutaceous, the seta3 not distinctly visible
under moderate power. The beak is slender, moderately and evenly
arcuate, fully as long as the prothorax in the male, and a little longer
in the female, not rapidly flattened toward apex and separated from
the head by a rather deep but broad impression ; antennae moderate,
the second funicular joint quadrate and but very slightly longer than
the third. Prothorax rather short, nearly one- half wider than long,
the sides strongly convergent from base to apex and broadly, dis-
tinctly arcuate, sometimes feebly prominent near apical third and
feebly constricted subapically, the disk with a narrow ill-defined
impunctate line, the punctures coarse, deep, not very dense and
unevenly distributed. Elytra a little wider than the prothorax,
fully twice as long, a little longer than wide and hemi-elliptical
behind the humeri, the disk coarsely, deeply grooved, the intervals
fiat, subequal throughout and about one-half wider than the grooves,

fused, larger and generally forming a more even single series on
the fourth and occasionally, also, on the second and sixth intervals.
The prosternum is deeply and abruptly sulcate, the sulcus becoming
shallow and coarsely punctate between the coxse which are separated
by about their own width. Length 4.3 mm.; width 2.1-2.2 mm.

6 Pseildobaris lllgubris n. sp. — Oval, moderately robust, strongly
convex, black throughout and polished, the setse sliort, sparse but distinct,
not condensed at the base of the third interval and without longer scattered
squaraules. Head finely, distinctly, the beak rather coarsely, punctured,
more densely in the male, strongly arcuate and quite distinctly longer than
the prothorax in both sexes, the antennae moderate, with the second funicular
joint distinctly longer than the third. Prothorax nearly one-third wider than
long, the sides subparallel or very feebly convergent and nearly straight to
apical third, then strongly rounded and convergent to the apex, the latter

transverse, the median lobe small but prominent, broadly rounded at apex ;
disk with a narrow ill-defined impunctate line which does not attain the apex,
the punctures rather fine, scarcely one-fourth as wide as the scutellum and
dense, somewhat unevenly distributed and very narrowly separated. Elytra
hemi-elliptical, distinctly longer than wide, not quite twice as long as the
prothorax and a little wider than the latter ; disk with moderately fine but
very deep abrupt grooves, the intervals flat, subequal, about twice as wide as
the grooves, each with a single series of somewhat small, shallow, moderately
remote punctures. Prosternum deeply, abruptly sulcate, the coxae rather
small and separated by a little more than their own width. Length 3.0-3.3
mm. ; width 1.3-1.6 mm.
New Mexico (Albuquerque).
A rather small species, resembling nigrina in outline, but with
smaller, feebler interstitial punctures and devoid of scattered squam-
ules ; from angusta it is at once distinguishable by its much more
broadly oval form. The smallest and narrowest specimen before
me is a female, the largest a male. Four specimens.
I have united with this species a still siiialler specimen from
Te.xas, which differs in its slightly coarser and very dense pronotal
punctures and scarcely larger but much deeper interstitial punc-
tures; it possibly represents a distinct species.

Oval, subcylindrically convex, rather polished, deep black through-
out. The beak is slender, evenly, rather strongly arcuate and equal
in thickness from base to apex, just visibly longer than the protho-
rax in the male, but nearly one-third longer than that part in the
female, the antennae normal, with the second funicular joint about
one-half longer than the third. Prothorax very nearly as long as
wide, broadly constricted near the apex, the sides nearly parallel in
basal two-thirds, the disk rather coarsely, densely punctate, the
punctures two-fifths as wide as the scutellum and separated by less

than one-half of their own diameters, the niedian impunctate line
oljsolete. Scutelluni small, transverse, impressed in the middle.
Elytra quite distinctly wider than the prothorax and about twice
as long, cylindrical and parallel in basal two-thirds, then semicircu-
larly rounded behind ; disk with rather fine, very deep grooves, the
intervals flat, equal, twice as wide as the grooves, each with a single
series of small, feeble, distant and transverse punctures. The
impression of the abdomen in the male is rather narrow and exces-
sively feeble. Length 2.6-3.3 mm.; width 1.0-1.3 mm.
Iowa and Kansas, five specimens. The setae of the elytra are
small, sparse, inconspicuous and unmixed with long dispersed
squamules, and by this means, as well as its more slender form,
angusta can be separated at once from nigrina.
The change of name proposed by Dr. LeConte is unnecessary, as
Pseudobaris is a genus so widely separated from Baris, that there
cannot be a plausible possibility of its supi)ression.
8 Pseildol»aris nigrina Say — Cure, p. 31 ; Ed. Lee, I, p. 295 (Bari-
dius).
A very common and widely distributed species, occurring over
the entire extent of the United States. It is moderately robust,
oval, strongly convex, black and polished throughout, the beak
strongly, evenly arcuate, slender and about one-third longer than
the prothorax in the female, but stouter and only equal to the latter
in the male. The prothorax is fully two-fifths wider than long, the
sides broadly arcuate and convergent anteriorly, gradually becom-
ing parallel in basal half, the apex feebly constricted at the sides ;
base transverse, with a very small but prominent median lobe, the
disk very deeply and densely punctured, with a narrow, more or
less incomplete impunctate line, the punctures rather coarse, about
one-half as wide as the scutelluni and almost in mutual contact.
Elytra fully twice as long as the prothorax, the stria? deep but not
very coarse, the intervals flat, equal, about one-half wider than the
grooves, each with a single series of coarse, rather deep, rounded
and not very close-set punctures, the ordinary setae scarcely observ-
able, the widely dispersed white squamules distinct, and condensed
at the base of the third interval. Prosternum normally and abruptly
sulcate. Length 2.5-3.5 mm.; width 1.0-L6 mm.
I have before me a series of over seventy specimens, from all
parts of the country, from New York and Florida (Key West), to
Coleopterological Notices, IV. 559
California (Lake Co.). The interstitial punctures sometimes become
very coarse, deep and approximate, but I can perceive no such
departures of structure as might call for a division into distinctly
defined subspecies.
9 Pseildobaris caelata n. sp. — Rather broadly oval, moderately con-
vex, polished, intense black throughout. Head finely, distinctly punctate
toward apex, the beak coarsely, deeply, subrugosely so at the sides, evenly
but not very strongly arcuate, robust, gradually flattened through apical half,

distinctly shorter ; antennse moderate, the second funicular joint about one-
half longer than the third. Prothorax rather short, nearly one-half wider
than long, the sides subparallel and nearly straight in basal three-fourths,
tlien strongly rounded and convergent to the apex, which is broad, truncate
and very briefly subtubulate ; base broadly, deeply bisinuate ; disk without
trace of median line, coarsely, rather densely, very deeply punctate, the punc-
tures regular, abrupt and perforate, circular, three-fourths as wide as the
scutellum and separated by much less than one-half of their own diameters.

about one-fourth longer than wide, nearly twice as long as the prothorax, and,
at the distinctly tumid humeri, a little wider than the latter ; sides distinctly
convergent behind the humeri, the outline hemi-elliptical ; disk not very
coarsely but deeply grooved, the intervals flat, equal, about twice as wide as
the striae, each with a single series of moderately distant, coarse, transversely
rugose but not very deep punctures ; setae very minute and not distinct, but
mingled with long white widely dispersed squamules, distinctly condensed at
the base of the third interval. Abdomen rather sparsely punctate, the setae of
the under surface sparse but distinct, white. Presternum broadly, abruptly
but moderately deeply sulcate, the coxae small and separated by much more
than their own width. Length 2.6-2.8 mm. ; width 1.2-1.3 mm.
New Mexico (Albuquerque). Mr. Wickhara.
A very distinct species, not at all closely allied to any other but
assignable to the mg7-ina group, which is distinguished by the
widely dispersed white squamules of the elytra. The male has the
abdomen narrowly and distinctly impressed toward base. Four
specimens.
IIESPEROBARIS n. gen.
A single small species thus far alone represents this genus, which
is allied rather closely to Pseiidobaris. It agrees with Pseudobaris
in general habitus, but differs in several important structural modi-
fications of the under surface, relating especially to the form of the
prosternal impression and intercoxal process, also in the structure
of the antennae. The antennas are of the same general type as the
560 Goleopterological Notices, IV.
peculiar form distinguishing Rhoptobaris and Orthoris. The pygi-
dium beneath emarginates the fifth segment in a rather deeply sinu-
ous arc. In Pseudobaris the fifth segment is much less sinuate, the
pygidium being but slightly visible from beneath, but in Microbaris,
the latter is gradually, transversely tumid inferiorly and largely
visible behind the fifth segment when viewed from beneath.
1 Hesperol)aris suavis n. sp. — Oval, very convex, shining, black
tlirongliout, the legs rnfo-piceous ; setae extremely short, visible but not con-
spicuous, not intermixed with dispersed squamules ; sculpture rather dense.
Hfad rather deeply and somewhat closely punctate, strongly convex, the trans-
verse impression broad but strong, impunctate ; beak moderately arcuate,
slender, densely punctate at the sides, a little longer than the prothorax ; an-
tennre moderate, the first joint of tlie funicle longer than the next three, the
second exactly equal to the third, and both slightly transverse, joints two to
seven cylindrically coarctate and gradually wider, club elongate-oval as long
as the six preceding joints together, densely pubescent throughout, the basal
joint one-third the mass and not quite as long as the second. Prothorax but
very slightly wider than long, the apex nearly three-fourths as wide as the
base ; sides feebly convergent from base to apex and feebly arcuate, the apex
very obsoletely constricted ; base transverse, the median lobe small and ex-
tremely feeble, almost obsolete ; disk with a very narrow ill-defined impunc-
tate line, the punctures somewhat coarse, very dense, deep, one-half as wide
as the scutellum and very narrowly separated. Scutellum small, transversely
oval. Elytra one-fourth longer than wide, twice as long as the prothorax and
one-fourth wider than the latter ; sides almost straight and parallel in basal
three-fifths, then convergent, the apex narrowly subtruncate ; humeral tuber-
osities almost obsolete ; disk with not very coarse, abrupt but shallow, opaque
grooves, the intervals fiat, subequal, scarcely twice as wide as the grooves and
each with a single series of rounded close-set punctures, which become coarse
and deep toward base but gradually very fine toward the apex. Abdomen
coarsely, deeply punctate toward base, more finely so behind, the punctures
moderately dense. Length 2.4 mm. ; width 1.05 mm.
Texas (Austin) ; Missouri.
The type of this interesting species is a female. The specimen
from Missouri is a male, and has the prothorax a little shorter and
the elytral sculpture decidedly stronger.
MICROBARIS n. gen.
Another genus allied to Pseudobaris, necessitated by a minute
species which I took some years since at Galveston, Texas. In
general facies it is quite distinct from either Pseudobaris or Hespe-
robaris, but the small claws, connate at base, declare its relationship
with these genera.
(Joleopierological Notices, IV. 561
The anteniife are somewhat peculiar. They are slender, the joints
of the fanicle becoming but slightly wider toward apex, and with
the club very small, of imperfect development and probably possess-
ing less than the ordinary degree of sensitiveness ; the several joints
are not defined by distinctly traceable sutures, and the vestiture is
coarse and somewhat sparse, although tolerably uniform through-
out.
1 Microliaris $;alTestoilica n. sp. — Subcylindrical, strongly-convex,
polislied, black throughdut. Head minutely, the beak rather coarsely and
densely punctate, the latter subimpunctate toward apex and broadly along the
middle, slender, evenly, strongly arcuate and about two-fifths longer than the
prothorax ; antennae slender, scape short, inserted behind the middle, funicle
slender, the joints coarctate and but slightly transverse toward apex, the first
not as long as the next three, the second and third subequal and each dis-
tinctly longer than wide, the fourth not at all wider than long, club small,
elongate-oval, compressed, sparsely pubescent and rather shining, as long as
the preceding four joints together, its structure not distinct. Prothorax fully
two-fifths wider than long, the sides broadly, strongly arcuate in basal half,
becoming strongly convergent and straight but not in the least constricted
toward apex, the latter one-half as wide as the base, feebly arcuate ; base
transverse, the median lobe broad and very feeble ; disk wider at basal third

polygonally distorted. Scutellum very small, rounded. Elytra one-half longer
than wide, a little more than twice as long as the prothorax and very slightly
wider than the disk of the latter, cylindrical in basal two-thirds, then gradually,
parabolically rounded, the humeral tuberosities obsolete ; disk with extremely
fine but deep and abrupt impunctate strife, the intervals flat, subequal, four
or five times as wide as the strise, each with a singe series of very minute
remote and feeble punctures, each bearing a small but distinct subrecumbent
silvery seta. Abdomen not very finely, strongly but rather sparsely punctured.

TRICHOB4RIS.
LeConte— Proc. Am. Phil. Soc , XV, p. 287.
The genus defined under this name by LeConte is one of the
most highly specialized of the present group of Barini. It is not
at all closely allied to Pseudobaris, although assigned at the present
time to the section containing that genus because of the similarity
in structure of the tarsal claws; these differ somewhat, however,
in being occasionally slightly unequal in length. It has no special
562 Coleoplerological Notices, IV.
affinity with Rlioptobaris. The squamose vestiture so higlily de-
veloped in the Centrini is also one of the most characteristic features
of Trichobaris, g-iving it a peculiar and easily recognized aspect
among the semi-glabrous genera with which it must be associated,
for it is easily distinguishable from Pycnobaris by its oblong form.
The elongate parallel outline of the body is however not peculiar to
this genus, being exhibited equally well in Stictobaris.
In Trichobaris the prosternum is broadly and feebly impressed
along the middle and narrowly separates the coxa3, the formation
of these parts being nearly as in Biris. The scutellum is large,
strongly transverse, broadly, deeply impressed and with the sides
acutely angulate, occasionally being prominent and more or less
reflexed toward apex or corniform, a development especially char-
acteristic of the present genus, although suggested rather strongly
in the first section of Baris.
The vestiture consists of broad scales, sometimes both above and
beneath, but often replaced by long slender squamules on the upper
surface; they are always recumbent and often subdenuded in vari-
ous limited areas, especially in two small spots at the base of the
pronotum, in two large subconfluent areas at the sides of the pro-
thorax beneath, and, in mucorea, also in three small spots at the
base of the beak ; these spots are not really denuded, but are clothed
with smaller and more slender piceous-black squamules. On the
abdomen there is always a large subquadrate area more or less
completely glabrous, occupying the median portions of the two or
three last segments; this is independent of the sex of the individual.
The antennal club varies in structure nearly as in Plesiobaris,
enabling us to group the species as follows: —
Antennal club moderately large, much longer than wide, with the basal joint
constituting less than one-half of the mass ; vestiture variable but with
the squamules always oblique at the sides of the elytral intervals ; body
generally subdepressed above, the prothorax always more or less quasi-
denuded beneath at the sides.
Vestitnre of the upper surface consisting of slender squamules, which do
not completely conceal the sculpture.
Pronotum simply punctate, without impunctate and subcarinate median
line; antennal club robust and abrupt 1 triiiotata.
Pronotum densely and continently punctate, sometimes longitudinally
rugose, the sides more or less feelily sinuate just behind apical third ;
antennal club more slender and elongate, less abrupt, the outer funicu-
lar joints more transverse ; pronotum with a narrow impunctate median
carina; size larger, the vestiture denser 2 mucorea
Coleopterological Notices, IV. 5G3
Vestiture consisting of large, broad, moderately dense scales ; punctures of
the pronotum large, deep, circular and distinct, with a narrow carinate
impunctate line ; basal denuded spots not distinct 3 insolita.
Antennal club more robust and conoidal, shorter and with the basal joint
constituting one-half of the mass ; vestiture consisting of more or less
broad scales, more densely placed, not conspicuously oblique at the sides
of the elytral intervals ; body more convex, the prothorax never with sub-
denuded spots at the sides beneath.
Abdominal impression of the male normally clothed with long recumbent
scales ; body very robust ; basal denuded spots of the pronotum large
and distinct 4 COinpacta
Abdominal impression of the male bristling with erect robust and pointed
hairs ; body narrow and subcylindrical ; basal subdenuded spots of
the pronotum almost completely obsolete.
Antennal club robust, much wider than the outer joints of the funicle ;
anterior coxae separated by about one-third of their own width ; elytral
striae indicated by narrow partings of the vestiture 5 texaiia
Antennal club exceedingly small, scarcely wider than the outer joints of
the funicle ; anterior coxae separated by one-half of their own width ;
elytral striae totally obliterated by the vestiture, the latter excessively
dense and composed of much broader scales ; body still narrower.

former sex, but a little shorter in the latter, the basal joint but
slightly more than one-third the total length, the second funicular
joint one-half longer than the third. The male is generally larger
than the female, and, in both sexes, the median parts of the third
and fourth ventral segments are abruptly denuded. The prosternum
is rather narrowly but distinctly impressed along the middle, the
anterior coxa^ being separated by about one-fourth of their own
width. Length 3.0-4.4 mm. ; width 1.2-1.75 mm.

Much larger and broader than triuotata, the vestiture rather more
robust and much closer but not extremely dense, white, the squam-
ules long and slender, directed transversely on the pronotum and
oblique and interlacing along the sides of the elytral intervals, be-
coming large and reddish-yellow along the anterior margin of the
pronotum, broad and overlapping beneath and replaced by very
slender dark piceous squamules in a large spot involving almost
the entire flanks of the prothorax beneath, and in three small spots
at the sides and on the upper surface of the beak near the base, these
areas appearing as if denuded ; abdomen abruptly denuded at the
middle of the third and fourth segments. Head glabrous; beak

Southern and Lower California and Arizona. Differs very widely
from Irinotata, but perhaps identical with Boheman's vestita. It is
recognizable at once by its rather depressed upper surface, large
size and the subdenuded area at the sides of the prothorax beneath.
Two of the specimens before me are smaller, with the vestiture
decidedly sparser, and with the pronotum strongly, longitudinally
rugo.se, and another much larger, with coarse and distinct pronotal
rugae, but with the vestiture den.ser than usual; this is therefore an
exceptionally variable species, or else I have confounded several
very closely allied forms, which cannot be advantageously studied
with such small series of specimens.

A single female example collected in the extreme southern part
of the State by Mr. Francis Kinzel, and kindly given to me by
Mr. Jiilich. It is somewhat intermediate between the texana and
trinotata groups of the genus, but is widely distinct from any other
species. The scales are shorter broader and larger than in any other
form known to me, not even excepting cylindrica, some of those
on the under surface of the prosternum being only slightly longer
than wide. The median parts of the third and fourth ventral seg-
ments are abruptly glabrous, the normal scales being replaced toward
the apex of each by very minute slender squamules sparsely dis-
tributed.

4 TricllO'baris COIupacta n. sp. — Oblong, strongly convex, robust,
black, densely clothed throughout with long white moderately wide recum-
bent scales, which are not distinctly oblique at the sides of the elytral inter-
vals, the scales not quite in mutual contact on the upper surface but very
nearly so, broad, denser and conspicuous throughout the under surface, ex-
cepting the usual abruptly glabrous spot at the middle of the third and fourth
ventral segments. Head glabrous, minutely, sparsely punctate ; beak robust,
short moderately arcuate, very densely and evenly squamose throughout,
distinctly shorter than the prothorax in both sexes ; antennre stout but long,
the second funicular joint longer than wide, obconical one-half longer than
the third, outer joints transverse, the club robust, conoidal, pointed, as long
as the four preceding joints combined, slightly pale in color, very densely
clothed throughout with small robust subrecumbent squamules, which are
white on the basal half, fulvous thence to the tip, the basal joint constituting
about one-half the mass, the annulations not very distinct. Prothorax two-
fifths wider than long, the sides feebly convergent and often broadly sinuate
to apical third, then strongly rounded and subprominent, thence strongly
convergent and broadly constricted to the apex ; disk with the two basal sub-
denuded spots large and distinct, the scales directed transversely. Scutellum

their own width. Length 4.5-5.3 mm. ; width 2.0-2.6 mm.
Southern California ; Arizona.
Of this distinct species I have before nie a series of about fifty
specimens. It may perhaps be confounded at first sight with
miicorea, but is shorter and stouter, the upper surface more convex
and the sides of the prothorax less acuteh" prominent. The scales
are broader and denser and are not replaced by piceous squamules
at the sides of the prothorax beneath, and are not oblique, or only
feebly and accidentally so, at the sides of the elytral intervals. The
male has a broad feeble and normally squamose impression in basal
half, and the fifth segment is as long as the two preceding combined,
with a small shallow emargination at the apex, from the bottom of
which there projects a short dentiform lobe, analogous to that of
Desmogli/ptus crenatus.

prothorax, the antennas stout, the second and third funicular joints
equal and slightly wider than long, the outer joints becoming ex-
tremely wide and subcontinuous in outline with the club, the latter
small but thick, only slightly longer than wide, conoidal, densely
pubescent, the basal joint constituting rather more than one-half
the mass. Prothorax scarcely one-third wider than long, with the
sides straight and parallel to apical third, then broadly rounded and

densely punctate, without impunctate line. Elytra a little wider
than the prothorax and about two and one-third times as long,

striation concealed by the vestiture, the stria; feebly indicated by
fine partings of the scales, which are not oblique along the sides of
the intervals. Prosternum distinctly impressed, separating the
coxae by about one-third of their own width. Length 4.3-5.1 mm. ;

Texas and Colorado. The third and fourth ventral segments are
denuded toward base in the middle, and, in the male, there is a
large elongate flattened or very feebly impressed area in basal half,
extending substantially to the base, in which the normally recum-
bent scales become longer, more slender, stiff and semi-erect setae;
there is also a small spot in the middle of the fifth segment in which
the vestiture is similarly modified.
n Triclioliaris cylindrica n. sp. — Parallel, subcylindrical, convex,
vei'y narrow and elongate, black ; integuments concealed above by an exces-
sively dense covering of large wide strigose scales, tVie denuded pronotal spots
feebly indicated on the basal margin only, the scutellum glabrous. Head
glabrous, opaque, almost impunctate, the transverse constriction very strong
liut not grooved and caused, as usual, by the pronounced gibbosity at the
base of the beak, the latter strongly, evenly arcuate, moderately robust,
densely squamose, scarcely as long as the prothorax in the male, the antennae
nearly as in texana but less stout. Prothorax one-fourth wider than long in
the male, but still longer in the female, constricted near the apex, the sides
broadly rounded, gradually becoming parallel and nearly straight in basal
half; base transverse, broadly bisinuate; disk evenly, extremely densely
punctate, without trace of median line, the surface completely concealed by
the large transversely directed scales, which are in mutual contact. Scutellum
moderate, transverse, broadly, deeply impressed but not so acute and promi-
nent at the sides as in texana. Elytra a little wider than the prothorax and
nearly two and one-half times as long, parallel, abruptly and broadly rounded
at apex, the pygidium feebly oblique and visible behind, the humeri slightly

scales, which are not even finely parted along the strife. Abdomen densely
squamose, middle parts of the third and fourth segments glabrous toward
base only. Prosternum not distinctly impressed, separating the small coxse by
fully one-half of their own width. Length 8.5-4.7 mm. ; width 1.3-1.7 mm.
Arizona.
Somewhat allied to texana, but quite different in its still narrower,
cylindrical form and denser vestiture, larger suboval scales which are
in close contact throughout, in the smaller and more distant ante-
rior coxtB and less impressed prosternum.
In the male there is, at basal third of the abdomen, a small elon-
gate-oval flattened area in which the scales become bristling semi-
erect and acutely pointed sette.
Several specimens before me are almost completely denuded, and
the pronotal punctures are readily observed to be fine deep and
frequently subcoalescent in a longitudinal direction, but not forming
rugise like those occasionally seen in mucorea, in which species also
the sculpture of this part is much coarser. Anteriorly the constric-
tion which is really strong, although not very distinct when nor-
mally squamose, is traceable entirely across the dorsal surface, the
sculpture in the constriction consisting of strong, longitudinal and
coarser rugiform ridges.
RHOPTOBARIS.
LeConte— Proc. Am. Phil. Soc, XV, p. 287.
The single species constituting this genus has nearly all the
generic characters of Orthoris, but seems to differ sufficiently in tlie
form and structure of the beak, prosternum and scutellum to fully
warrant its generic isolation.
The beak is rather robust, moderately and evenly arcuate, differs
considerably in the two sexes, and is separated from the head by
an extremely broad and feeble transverse impression. Epistomal
lobe short, limited at each side by a very small oblique fissure, and
narrowly and deeply sinuate at the apex. Antennae somewhat
slender, the club elongate-ovoidal, densely pubescent and indis-
tinctly annulate, the basal joint composing about one-third of the
mass. The mandibles are well developed, arcuate, decussate when
closed and deeply notched at apex.
The prosternum is flat, not distinctly tumid before the coxae and
separates the latter by one-third of their own width. Prothorax at
Coleopterological Notices, IV. SfiO
base quite perceptibly narrower than the elytra. Scutellum trian-
gular, flat, nearly as long as wide, deeply and densely sculptured
like the surrounding surface of the elytra and not impressed. The
legs are moderately long, the tarsi slender, the ungues well developed
and unusually thick, as in Orthoris.
The oblique pygidium of Rhoptobaris and Orthoris appears to
indicate a certain affinity with the Centrini, and, although this
character occurs also in the Barini proper, it would seem more
natural to place these genera as near the Centrini as possible. The
elongate antennal club, also, is more of a centrinide than a baride
character, it being highly developed for example in Cylindrocerus.
1 Rlioptoliaris canescens Lee. — Proc. Am. Phil. Soc, XV, p. 287.
Elongate-oval, black throughout and strongly convex, subopaque,
the elytra less densely sculptured and a little more shining, the
vestiture consisting of very short, moderately dense setae, giving a
gray pruinose appearance to the surface. The beak is rather stout,
distinctly arcuate, one-third longer than the prothorax in the male,
but nearly one one-half longer than the latter in the female and
distinctly more slender ; antennae inserted slightly beyond the mid-
dle, the funicular joints small and subequal, the club elongate, fusi-
form, abrupt, very densely pubescent, not distinctly annulate, a little
shorter than the funicle in the male, but fully as long as the latter
in the female. Prothorax in the male two-fifths wider than long
with the sides strongly convergent from base to apex and evenly
moderately arcuate throughout, not in the least constricted, in the
female scarcely perceptibly wider than long, the sides being very
feebly convergent from base to apex ; disk without impunctate line,
finely and very densely punctate throughout. Elytra in both sexes
abruptly and quite distinctly wider than the prothorax, and, in the
male, nearly three times as long as the latter, in the female not
quite two and one-half times longer, the striae deep and abrupt, not
very coarse, the intervals about three times as wide as the striae,
finely, confusedly and very densely punctate throughout. The male
is much larger and more robust than the female, and has, at the
apex of the fifth segment, a short obtusely rounded dentiform lobe.
Length 3.4-4.0 mm.; width 1.3-1.6 mm.

ORTHORIS.
LeConte— Proc. Am. Fliil, Soc, XV, p. 286.
The external appearance of the species composing this genus cer-
tainly conveys but little idea of their true affinities, for, as remarked
by Dr. LeConte, they quite closely resemble Orchestes. Rhopto-
baris constitutes, howev'er, an excellent connective bond in every
way with the more usual habitus of the tribe.
There are several inaccuracies in the original diagnosis of the
genus, which is drawn from the female alone. The beak is stated
to be "not curved," and the prosternum "broadly though not deeply
sulcate in front." The beak, even in the very long slender form
occurring in the female of C7-ofchi, is feebly, though very sensibly,
curved, and in the male of crotchi and female of cxjlindrifer, it
becomes quite conspicuously so. The modification of the prosternum
is peculiar, this part being rather narrowly and deeply impressed
along the middle, but not at all abruptly sulcate ; the peculiarity
consists in the fact that the canaliculation is not a depression below
the general surface of the prosternum as in other genera, but is
caused by a tumid elevation before each coxa, the impression being
an intervening valley between the two prominences.
The beak in Orthoris is slender and separated from the head by a
transverse impression, which is narrower and much stronger than
in Rhoptobaris; but in the structure of the prostomal lobe and
mandibles the two genera are nearly similar. The antennae are of
the same aberrant t3^pe as in Rhoptobaris, the club being sometimes
greatly elongate, a form feebly suggested in the genus Hesperobaris.
The front coxse are very narrowly but distinctly separated.
Our two species may be easily recognized as follows: —
Lusti'e alutaceous ; setse longer, confusedly dispersed on the elytral intervals :
pronotal punctures finer and dense ; beak in the female very long and
slender, the antennal club in that sex not quite as long as the funicle.

slender, just visibly but evenly arcuate and three-fifths longer than
the prothorax in the female, stouter, much shorter and distinctly
arcuate near the Imse and apex in the male, the antennal club in
the female scarcely perceptibly shorter than the entire funicle, but
not much longer than the preceding six joints in the male. The
prothorax is small, conical, truncate at apex and very feebly con-
stricted anteriorly, the punctures scarcely more than one-fourth as
wide as the scutellum and separated by barely one-half of their own
widths. Elytra abruptly fully two-fifths wider than the prothorax,
two and one-half times as long as the latter, one-third longer than
wide ; sides parallel and straight, the apex broadly and abruptly
rounded, the striae deep ; intervals three to four times as wide as
the strife, finely and feebly, not very densely, confusedly and sub-
asperately punctate. Fifth ventral segment longer than the pre-
ceding two combined, acutely rounded in the female, a little more
obtuse in the male. Anterior coxie separated by nearly one-fourth
of their own width. Length 2.8-3 8 mm.; width 1.1-1. OS mm.

2 Ortlioris cylindrifer n. sp. — General form as in crotchi, but polished
and more sparsely setose, the setffi moderately long, stiff, erect and bristling
on the beak and pronotum, but recurved on the elytra, forming a nearly even
single line on each interval. Head coarsely punctured, setose, the transverse
impression narrow, strong and impunctate, the beak moderately densely
punctate, rather slender, strongly arcuate at base and near the apex, some-
what short, scarcely more than one-third longer than the prothorax in the
female ; antennae long, the first funicular joint robust and as long as the next
three, two to seven small, subequal, club very long, fully three times as long

entire funicle, abruptly wider than the seventh funicular joint, the sides
straight and subparallel or very feebly divergent thence to apical third, then
gradually pointed, indistinctly annulate, the basal joint longer than wide.
Prothorax small, nearly one-half wider than long, the sides convergent from
the base, feebly but distinctly arcuate, very obsoletely constricted near the

CEKTRIWUS.
Schonherr — Curcul. Disjj. Meth., p. 308.
Within the wide limits permitted by the short and somewhat
ambiguous definition of Schonherr, I here regard as Centrinus,
those species of Barini which have the pygidium concealed in both
sexes, or never with more than the mere tip exposed, the femora
unarmed, the mandibles elongate, prominent, not in the least decus-
sate when closed, with the inner edge entirely free from notches
and denticulation, and the tarsal claws free and divergent. In
addition, it should be stated that the species are, with very few ex-
ceptions, rhomboidal or rhomboid-oval to a greater or less degree,
and are all more oi' less squamose. This definition, also, will at
least not exclude those species defined as Centrinus by Pascoe
(Ann. Mag. Nat. Hist., Oct. 1889, p. 322) viz: "Claws free;
canal nearly obsolete or absent ; anterior coxae separated ; proster-
num lower than the coxae ; elytra broader than the prothorax."
With these characters are associated others, even in our own
somewhat limited fauna, of considerable variety. The beak may
be very slender, comparatively robust, or slender and inflated near
the base, strongly and evenly or feebly and unevenly arcuate and
variously compressed and flattened, the antennae inserted beyond
or behind the middle and the prothorax tubulate or not. The ante-
rior coxse may be narrowly or quite widely separated, the prosternum
flat or variously impressed, foveate or sulcate, often very differently
modified in these respects in the sexes of the same species. Finally,
the secondary sexual modification of the male may be radically dif-
ferent in kind, consisting either of short or long ante-coxal corneous
processes of the prosternum, or of a dentiform extension of the
anterior trochanters, or of a short erect tooth-like process projecting
from the inner side of the basal joint of the antennal club, never,
however, by a combination of any of these three modifications; in
Coleopterological Notices, IV. 573
some cases, the male appears to be entirely devoid of secondary
sexual characters.
In fact within the limits of the genus as thus defined by mandi-
bular structure, many characters which are of generic importance
elsewhere, such as the degree of separation of the coxae, nature of
the prosternal impression and conformation of the prothoracic apex,
lose all significance of this kind and are merely useful in defining
groups. In all probability some of these sexual groups are worthy
of a separate designation, but with my present lack of sufficiently
exact knowledge concerning the numerous tropical forms, it would
l)e manifesth^ inappropriate to do more than simply indicate those
which exist within our own fauna ; this has been attempted in the
following table : —
Male with an erect or oblique process of greater or less length before each
anterior coxa ; antennal scape not attaining the eye ; tarsal claws slender,
not excavated beneath.
Anterior coxse narrowly separated ; body robust.
Beak thick, the antenn;e inserted beyond the middle, at least in the male ;

rior trochanters dentate; anterior coxae moderately separated, the pro-

or dentiform process ; pygidium with the apical portion exposed in both
sexes ; anterior coxje narrowly separated, tlie prosternum generally with
a deep transversely oval pit behind the apical margin ; basal impression
of the beak almost obsolete ; scutellum rather large and always densely
albido-pubescent X

The identity of subgenus "X" with Odontocorynus Sch., is in-
ferred from the description given by Lacordaire. We have no
species in which the antennal joints four to seven are internally
spinose, but several in which the two or three outer joints of the
funicle are slightly prolonged and acuminate within. The Mexican
Gentrinus larvatus and tonsilis of Boheman, also belong to this
subgenus without doubt.

Robust, oval, convex, piceous, the integuments moderately shin-
ing, somewhat densely clothed with elongate-oval whitish scales on
the pronotuni in the middle through basal half and toward the sides,

with an elongate-oval, excessively deep excavation, with its edges
rounded, the coxa? sepai'ated by but slightl}' more than one-fourth

vertically for a short distance, then flexed abruptly and obliquely for-
ward, becoming finely acuminate. Length 5.8 mm. ; width 2.8 ram.
Missouri. Cab. LeConte. Represented by the unique type. The
narrowly vittate elytra will readily serve to identify this distinct
species.
3 Centriiitis striatirostris Lee. — Proc. Am. Phil. Soc, XV, p. 309.
Robust, oval, convex, piceous and shining, the vestiture sparse,
whitish, consisting of very elongate narrow scales and finer hair-
like squamules indiscriminately mingled on the elytra, the finer
squamulcs not noticeably darker in color; on the under surface they
are broader and denser, and on the pronotum are also coarser toward
apex and at base near the sides and in the middle, also in a large
conspicuous spot at each side of the scutellum. The beak is rather
stout and feebly arcuate, but slightly longer than the head and pro-
thorax, deeply punctate and longitudinally rugose at the sides, the
antennse inserted just beyond the middle, the second funicular joint
less than one-half as long as the first and about one-half longer than

4 Ceiitrinus niodestus Boh. — Sch. Cure, III, p. 772.
A well-known species of robust, oval, strongly convex form and
piceous color, sparsely sprinkled with coarse white scales and nar-
rower brownish squamules above, and more densely covered with
whitish scales beneath. The beak is about one-half as long as the
body, evenly but not very strongly arcuate, moderately stout,
slightly gibbous at base, so that it is separated from the head by an
unusually deep and sharply marked transverse impression ; antennae
normal, inserted a little beyond the middle, the scape short, extend-
ing about two-thirds the distance to the eyes, the second funicular
joint scarcely more than one-half as long as the first. Prothorax
strongly constricted and almost tubulate at apex. Prosternum
with a deep oval abruptly glabrous subapical spot, which is very
deeply and transversely excavated at the bottom, and continued
posteriorly by a feebly defined canaliculate and squamose impres-
sion, which becomes narrower and gradually evanescent before the
coxa\ the latter large and separated by scarcely more than one-
fourth of their own width, with the middle of the anterior margin of
the acetabula elevated in a feeble cusp-like prominence, or short corne-
ous process in the male. Length 4.0-4.5 mm.; width 2.3-2.5 mm.
The four specimens in my cabinet are from Pennsylvania and
Florida. In well preserved specimens a small spot of dense scales
is evident at each side of the scutellum, and another just before
each humeral callus, the former not being as large or conspicuous,
however, as in striatirostris.
5 Ceiltrinus tortuosus n. sp. — Ratlier robust, feebly rhomboid-oval,
convex, shining, coarsely sculptured, piceous-black, the antennse paler ; ves-
titure very sparse above, consisting of large white scales and small narrow-
brown squamules indiscriminately mingled on the elytra, dense beneath, and
with the scales white, short, broad and truncate. Head almost completely
impunctate, the transverse constriction abrupt, almost in the form of a groove ;
beak rather stout, feebly arcuate, very coarsely, deeply, longitudinally punc-
tate and rugulose at the sides, a little longer than the head and prothorax in
the male, the antennse inserted distinctly beyond the middle, the scape short,
second funicular joint one-half as long as the first and nearly as long as the
next two, club well developed, oval, abrupt, densely pubescent, about as long
as the preceding five joints together and with its basal joint composing about
one-half of the mass. Prothorax three-fifths wider than long, the sides dis-
tinctly convergent and almost straight from the base to apical third, then
broadly rounded and convergent to the deep apical constriction, the apex
strongly tubulate, truncate, not quite one-half as wide as the base, the latter
transverse and perfectly straight, the median lobe less than one-third of the

total width, abrupt, prominent and rounded ; disk with coarse oblique parallel
wavy rngse, and with a narrow subcarinate itnpunctate line in basal two-
thirds. Scutellum glabrous, small, subquadrate, broadly emarginate at apex
and deeply impressed along the middle. Elylra at the large and somewhat
prominent humeri, conspicuously wider than the prothorax, distinctly more
than twice as long as the latter, the sides rapidly convergent from base to
apex and feebly arcuate, the apex narrowly rounded ; disk with moderately
coarse, deep, abrupt, finely and remotely punctured strise, the intervals flat,
three times as wide as the grooves, coarsely, not densely punctato-rugulose.
Length 3.S mm. ; width 2.0 mm.
Texas.
The single specimen is a male and agrees nearly in prosternal
structure with modestus, the surface being very broadly and feebly
impressed, except just behind the apical margin, where there is a
large and transversely oval, extremely deep excavation. The cox»
are much more widely separated than in modestus, the interval
being equal to fully one-half of their own width, and the form of
the body is more narrowly oval ; it also differs greatly in pronotal
sculpture, the latter being finer and in the form of long oblique
rugfe. In the male the middle of the anterior margin of the ante-
rior acetabula has a small feeble cusp-like elevation as in modestus.

Somewhat broadly oval, convex, black throughout, densely and
uniformly clothed above with long more or less narrow lineate
squamules, pale ochreous-yellow to whitish in color, a little paler,
denser and much wider beneath. Beak similar in the two sexes, a
little longer in the female, very strongly arcuate, fully one-half as

second funicular joint but slightly elongate, not one-half as long as
the first and one-half longer than the third ; club abrupt, moderate,
oval, densely pubescent, nearly as long as the four preceding together
and with its basal joint composing nearly one-half of the mass.
Prothorax fully one-half wider than long, conical, with the sides
feebly arcuate, feebly constricted near the apex, the squamules
denser and broader on the small but prominent basal lobe. Elytra

the coxae separated by scarcely more than one-third of their width;
in the female with a small but extremely deep excavation near the
anterior margin, bordered on each side by a longitudinal ridge, ex-
terior to which there is also a deep excavation, devoid of corneous
processes and with the coxa^ separated by fully two-thirds of their
own width. In the male there is a rounded very feebly impressed
spot near the base of the abdomen, which is abruptly nearly gla-
brous, and in which the ordinary scales become semi-erect and each
deeply split into two or three hair-like processes. Length 2.1-2.7
mm.; width 1.0-l.fi mm.
New York, Florida, Nebraska, Arkansas and Arizona. The
sexual modifications in this small group of species are remarkable,
especially in the divergence of prosternal impression, and in degree
of separation of the anterior coxae.
7 Centrinus altootectlis n. sp. — Rather broadly oval, convex, black,
densely and uniformly clotlied with rather wide white scales, which are but
slightly broader and denser beneath. Head and base of the beak squamose,
the beak strongly, evenly arcuate and slender in both sexes, but scarcely
longer than the head and prothorax in the male, and fully one-half as long
as the body in the female; antennfs in the male with the basal joint of tlie
fnnicle as long as the next three, the second small, but slightly longer than
the third, three to five each a little longer than wide, the club small abrupt,
short, oval, scarcely longer than the preceding three joints together ; in the
female the club is less abrupt, larger and more elongate, with the basal joint
of the funicle barely longer than the next three. Prothorax fully one-half wider
than long, the sides distinctly convergent from the base and broadly arcuate,
rather strongly constricted behind the apex, the latter sometimes almost tubu-
late; base transverse and straight, the median lobe small but very prominent;
disk uniformly and very densely punctate and squamose. Scutellum very
small, almost concealed by the vestiture. Elfjtra hemi-elliptical, a little
wider than the prothorax and twice as long in the male, but relatively dis-
tinctly shorter in the female ; humeri moderately prominent ; strife rather
fine, very deep, the intervals flat, three or four times as wide as the strife,
densely punctato-rugulose. Prosternum in the male with an elongate-oval,
extremely deep excavation, the coxse separated by one-half of their own
width ; in the female, with a small rounded very deep pit just behind the
apical margin, also somewhat impressed laterally as in jiirumnus, and with the
coxpe separated by two-thirds of their own width. Length 1.75-2.5 mm. ;
width 0.7-1.3 mm.
Florida, Texas (Columbus).
In the male there is a long very slender finely acuminate horn
before each coxa, the process being inclined forward and very feebly

arcuate ; in the same sex there is a small semi-glabrous flattened
spot near the base of the abdomen, in which the ordinary scales
become very sparse small and narrow, but recumbent and not
modified in structure. This species may be readily distinguished
from picumnus by its broader white scales, shorter beak with more
pronounced sexual differences, by its smaller size and more slender
form. Twelve specimens.

8 Centriniis neglectlis Lee. — Proc. Am. Phil. Soc, XV, p. 310.
Similar in form and structural characters to perscillus, but clothed
densely throughout with ochreous-yellow scales, broad beneath,
narrow and slender above, where they are unevenly mixed with
darker brown scales of the same kind, the brown scales forming
also two distant subapical spots. Beak slender, very strongly
arcuate, not quite one-half as long as the body in the female, the
antennae inserted a little behind the middle, the scape rather abruptly
clavate, extending barely three-fourths of the distance to the eyes;
second funicular joint slender but short, scarcely one-half as long as
the first and a little longer than the third, the outer joints larger,
the club as in perscillus Prosternum flat, abruptly declivous ante-
riorly to the transverse constriction, the coxte moderate, remote,
separated by distinctly more than their own width. Length 3.6-4.0

Texas, Louisiana and Kansas. The specimens before me are
females, but the male is said to have a short corneous process
before each coxa. The statement in the original description that
the second funicular joint is "nearly as long as the first," is a con-
spicuous error. This species is closely allied to perscillus.
9 CeiltrinilS grisesceus n. sp. — Feebly rhomboideo-elliptical, convex,
rather dull, black throughout, densely clothed throughout beneath with large
wide yellowish-white scales, and, on the upper surface, with squamules which
are narrower, and luteous-white and dark brown intermingled, the latter more
evident in two distant spots near the apex as in neglectus. Beak strongly
arcuate, relatively not longer and but slightly more slender in the female
than in the male, but notably more arcuate in the former sex, not quite one-
half as long as the body; antennse inserted as in neglectus, the second funicular
joint much more slender than the first and not quite one-half as long, much
.shorter than the next two together ; club about as long as the preceding four
joints combined, not very abrupt, densely pubescent, with the basal joint
composing but slightly less than one-half of the mass. Prothorax one-third

with the median lobe small but abrupt and prominent, rounded ; apical con-
striction broad and feeble ; disk somewhat coarsely deeply and very densely
punctate, with a narrow, more or less incomplete impunctate line. Scutellnm
moderate in size, quadrate. Elytra slightly wider than the prothorax and
twice as long, the humeri rather prominent, the sides thence strongly conver-
gent and very feebly arcuate to the narrowly rounded apex ; striae fine but
deep, the intervals flat, three or four times as wide as the striae, confusedly,
rather coarsely punotato-rugulose. Prosternum broadly, distinctly impressed
in the middle in both sexes, but much more deeply so in the male the latter
having a short erect acuminate horn before each coxa ; anterior coxae rather
large, separated by barely their own width. Length 3.5-4.1 mm.; width
1.65-1.9 mm.
North Carolina (Ashevillo) ; Ohio; Illinois; Missouri.
Very closely allied to neglectus, but differing in its whitish and

short, not quite one-half as long as the first and but very slightly
longer than the third; club moderate, oval, densely pubescent, a
little longer than the preceding four joints together, and with the
basal joint constituting somewhat less than one-half the mass. Pro-
sternum flat, rather abruptly declivous anteriorly to the transverse
constriction, separating the coxte by quite distinctly more than their
own width. Length 3.7 mm.; width 1.85 mm.
The two specimens before me are apparently females, and are
from Kansas and Minnesota. I think that this is without doubt
the species described by Gyllenhal, and the species so identified by
LeConte (Proc. Am. Phil. Soc, XV, p. 310), having the second
funicular joint as long as the first and the prosternum deeph' exca-
vated, is probably some other species which remains unknown to me.
Coleopterological Notices, IV. 585
The species described hy Gyllenhal is said to be covered densely
with narrow scales, agreeing* with the present form, but in jjerscillus
Lee. the scales are especially noted as being "not linear but oval."

Arizona (Tugson). Mr. Wickham.
I have only seen the female, and the remarkable form of the beak,
reminding us strongly of Eunyssobia (Euehaetes Lee), is probably
peculiar to that sex, as it may be observed to a less degree in several
other species of this subgenus, and notably grisescens ; at any rate,
the peculiar basal enlargement is much more developed in the female
than in the male of that species.

The typical representative above described is a male. The species
is altogether distinct from any other here noted, and may be known
at once by the pale coloration of the integuments and the ochreous
scales.

Oval, convex, piceous-brown, the elytra rufous; vestiture not
very dense, ochreous-yellow, consisting of closer and broader scales

The two specimens before me are from New Jersey and Indiana.
It is somewhat singular that Dr. LeConte should have failed to see
the corneous prosternal processes in the male of this species; they
are quite conspicuous and must have been concealed by the anterior
femora in the specimens which he examined.

densely punctured and squamose throughout. Prosternura nearly flat, sepa-
rating the coxse by appreciably less than their own width. Length 3.3 mm. ;

New Mexico (Gallup). Mr. Wickham.
The single specimen is a female, but the species is very distinct
and allied only to perscitus. It differs from p)erHcitus in its much
larger size and stouter form, in the decidedly shorter relative length
of the intermediate and posterior tibia^., and in the pronotal punc-
tures which are here very close but circular in outline and not in
actual contact, while in perscitus they are coarser and polygonally
crowded. These two species belong to a peculiar type, distinguished
from the other allies of perscillus by the very much shorter, stouter
and evenly cylindrical beak.

Arizona (Santa Rita Mts.). Mr. Wickham. The single repre-
sentative before me is a female ; I have not seen the male. The
remarkable form of the mandibles and the robust excavated tarsal
claws, may ultimately necessitate the generic separation of this
species, for which Mr. Pascoe has already suggested a name.
The spots of the elytra appear to be denuded, but, as in all similar
cases in this genus, these areas are not really denuded but quite as
densely clothed with blackish and sometimes more slender squam-
ules.

In form and size this very distinct species is nearly similar to
penicellus, but the beak is shorter and the antennae of singular
structure. The male difiFers from the female in having the anterior
trochanters obtusely toothed. The hind til)ia3 are bent outward
slightly and feebly dilated at apex, the internal spur not visible and
the apical margin transversely truncate, a peculiarity of structure
which is very highl}'' developed in Eisonyx. Three specimens.

Texas (El Paso).
The extreme resemblance which this species bears to acuminatus
in every external feature is very remarkable, in view of the equally
striking difference in antennal structure, and in the more widely
separated anterior coxte. The single male before me has the ante-
rior trochanters obtusel}' dentate, the tooth lamelliform. The poste-
rior tibice are nearly as in acuminalits, although a little shorter, the
])Osterior femora are also a little shorter thicker and with more
arcuate external outline.

This species is so well known, and so easily recognizable by the
characters given in the table, that but little further need be said of
it. The antenna? are slender, rather long, the second funicular joint
very slender, fully two-thirds as long as the first and scarcely as
long as the next two together, the latter equal and each distinctly
elongate, the club small, rather abrupt, elongate-oval, pointed and
I)ut slightly longer than the three preceding joints combined, densely
pubescent and with its basal joint constituting scarcely two-fifths of
the mass ; the scape is slender, rather abruptly clavate and inserted
just beyond basal third. The prosternum is flat, extremely densely
squamose, feebly bitumorose at the apex, and with a transverse ex-
cavated groove at a sensible distance behind the apical margin, the
coxa?- rather large, somewhat prominent and separated by barel}^
two-thirds of their own width. Anterior trochanters small and
simple in both sexes. Length 3.5-3.8 mm.; width 1.7-1.9 mm.
The series before me is from Iowa and Indiana. I have seen no

face of very slender hair-like squaraules, disposed in nearly even approximate
lines on the elytra, and becoming coarse and denser scales about the scutellum
and in a subsutural area on each just behind the middle ; on the pronotum
they are coarser and denser near the base before the scutellum and at lateral
fourth ; on the under surface they become moderately wide and close, except
on the apical half of the prosternum, where they are very fine and sparse but
radiating from the peculiar antero-central point mentioned in the other species
of this subgenus. Head i^romiuently convex, finely, sparsely punctate, the
beak strongly arcuate in basal third, thence feebly arcuate and very thin
viewed laterally, but broad and flattened viewed anteriorly to the apex,

Texas.
From analogy in the case of capiUatus, if we regard as the female
the form having the beak more abruptly bent near the base and
more widely flattened, the unique type of nubecula is of that sex,
for the beak is even more noticeably flattened than in the species
referred to. In the male, the beak is but slightly shorter, and is
much more evenly and, on the whole, more strongh' arcuate than
in the female, and is C3iindrical, although feebly flattened very near
the apex. For the reasons stated, the male beak appears thicker
from a lateral point of view than that of the female, but from an
anterior point it is a little thinner.

This species is allied to capillatus, but differs in the much broader
and more uneven scales of the elytra, and in its very pale bright
rufous legs.

The description above given is taken from the male and in this
sex the pygidium is considerably exposed between the elytral apices,
and very oblique ; in the female it appears to be somewhat less ex-
posed. The body is more broadly rhomboidal than in the salebrosus
group, and the sexual differences in the structure of the beak are
not at all evident. The male is black, but the female is almost in-
variably more or less rufescent and has the prothorax shorter, the
pronotal punctures larger and sparser, and the antennal club simple.
This species is represented in my cabinet from New York, Indiana,
Missouri and Florida ; it also occurs in Brazil.

slender, cylindrical, smooth and minutely, sparsely punctured, ex-
cept just before the eyes, where the punctures become coarse and
close, but not rugose, the antennae inserted just beyond the middle ;
in the female the antennae are more slender and with a smaller sim-

The description is drawn from the male ; in the female the beak
is quite distinctly longer and rather more slender, evenly, some-
what strongly arcuate throughout, cylindrical, smooth, shining and
minutely, sparsely punctate except at base, the antenna? inserted
distinctly beyond the middle, and with the club unmodified.
This species is the most protean in its variations of any baride
which I have seen ; more especially in the vestiture of the upper
surface, which may consist of ver}^ slender sjjarse squa mules, or
robust oval dense and very conspicuous scales, with every inter-
grade between these limits. The series before me consists of nearly
sixty specimens.

29 Ceiltrinus pulTerulentusn. sp. — Oval, subrhomboidal, convex,
black, the aiitennal funicle gradually rufous toward apex, the club black ;
vestiture white, that of the upper surface consisting of small evenly and
sparsely placed truncate scales on the pronotum, generally larger and closer
along the ajjical margin ; on the elytra the scales are larger, rather sparsely

Described from the female. In the male the beak is deeply,
coarsely, longitudinally punctato-rugulose, with the antennae in-
serted far beyond the middle, the prosternum more deeply impressed
along the middle, and the anterior coxa3 still more narrowly sepa-
rated, but the very deep transverse subapical pit is almost similar
to that of the female. In antennal structure the male differs from
the female in having the second funicular joint shorter, the outer
joints more transverse and obliquely truncate at apex, and the

basal joint of the club witli a short acute erect tooth on the inner
side. This is a very distinct and interesting species.
The female from Colorado is very densely squamose above, and
the species probably varies in vestiture to as great a degree as
salehrosus.
CElVTRIiXOPUS n. gen.
In this genus the beak is long, very slender and strongly arcuate,
with the antennne inserted near basal third, the scape short and ex-
tending almost to the eyes, the basal joint of the funicle long, the
second short and the club rather small, with its basal joint unusually
large.
The mandibles are well developed, quite distinctly notched within
near the apex, but with the e^iternal outline nearly straight; when
closed they are scarcely at all decussate and form together an ante-
riorly prominent ogive. The prosternum is deeply canaliculate
along the middle in the female, and with a still deeper elongate-
oval excavation in the male, being armed in the latter sex before
each coxa with a well-developed, abruptly bent, corneous process.
The anterior coxse are somewhat prominent and narrowly separated,
being appreciably more approximate in the male than in the female.
The mes-epimera are exposed from above and the scutellum.is very
small and densely squamose. The pygidium is completely covered
in both sexes, and the met-opisterna moderately wide and generally
more densely squamose than the adjoining surfaces.
The form of the body is somewhat oblong-oval, the humeral callus
feebly developed, and the general habitus reminds us considerably
of Livwobaris grisea. In the male the abdomen is broadly im-
pressed in the middle toward base, the impressed area clothed with
more slender, sparser but recumbent squaraules. Our two species
may be identified by the following characters: —
Prothorax feebly transverse ; pronoliira not conspicuously trivittate, the scales
uniform in coloration but not in size and density ; elytra abruptly much
wider than the prothorax, the alternate intervals simply more broadly
squamose 1 lielvillllS
Prothorax more transverse ; pronotum with three distinct vittse, the squam-
ules of the intermediate regions not only finer and sparser but darker in
color ; elytra but slightly wider than the prothorax, with the alternate
intervals much more broadly, densely and conspicuously clothed with
paler scales 2 altei'uatus

the beak, antennae and legs more or less rufescent; vestitnre pale ochreous-
yellow, squamiform, the scales dense beneath especially on the met-episterna ;
on the pronotum they are fine on the flanks beneath, then coarser and closer
in a sublateral vitta, then sparse and fine to the median line where they are
again coarser and denser, especially toward base ; on the elytra they are more
broadly oval, more wjiitlsh and densely, unevenly distributed throughout all
the intervals, especially on the rather broader third, fifth and seventh. Hexid
densely punctured and squamose toward apex, the basal portions of the beak
also densely squamose but with the scales erect and bristling, the beak slender,
evenly, rather strongly arcuate, a little longer than the head and prothorax,
deeply, rather coarsely punctured and longitudinally furrowed but shining,
the two punctate grooves lying along the sides of the median impunctate line
especially evident ; antennae with the basal joint of the funicle rather longer
than the next three, the second but slightly longer than the third, the club
moderate, robust, abrupt, oval, pointed, as long as the preceding four joints
combined, densely pubescent, with the basal joint composing fully one-half
of the mass, the annulations strong, the successive rings decreasing rather
abruptly in transverse diameter. Prothorax one-third wider than long, the
sides very feebly convergent and nearly straight to sliglitly beyond apical
third, then broadly rounded, strongly convergent and feebly sinuate to the
apex, which is truncate and not quite one-half as wide as the base, the latter
transverse, broadly sinuate toward the median lobe which is very small but
abrupt and prominent ; disk densely, not coarsely punctured. Elytra abruptly
one-fourth wider than the prothorax, rather more than twice as long as the
latter, the outline hemi-elliptical, the humeri very small and scarcely at all
prominent ; disk deeply but not coarsely striate, the intervals flat and from
two to three times as wide as the grooves. Presternum with an extremely
deep elongate-oval excavation, and with a corneous process before each coxa,
the process very thick and erect at base, but then abruptly and angularly
bent obliquely forward becoming rapidly finely acuminate, the coxae rather
prominent, separated by about one-fourth of their own width. Length 1.9-2.7

The description is taken from the male, the female being similar
in form and structure of the beak and antennae, but having the pro-
sternum simply longitudinally and deeply channeled, the channel
squamose and limited at the sides by an obtusely elevated ridge;
the coxaj are a little less approximate, being separated by nearly
one-half of their own width. The measurements given above are
taken from the extremes of a series of over one hundred specimens.

former forming three vittse on the pronotum and densely clothing intervals
tliree, five and seven, the line of the third and seventh uniting near the apex
and continuing thence as a single short line to the apical angle ; other inter-
vals having very narrow inconspicuous lines composed of more slender, whitish
and brown squamules. Head densely punctate and squamulose anteriorly,
the base of the beak bristling with erect scales, the beak slender, smooth,
polished, rather coarsely but not densely lineato-punctate, strongly, evenly
arcuate and a little longer than the head and prothorax, the basal joint of the
funicle as long as the next three, the club small but robust, oval, densely
pubescent, scarcely as long as the preceding four joints combined, with the
basal joint composing nearly three-fifths of the mass, the remaining rings

parallel and feebly arcuate in basal two-thirds, then rounded, strongly con-
vergent and broadly constricted to the apex, which is about one-half as wide
as the base, the latter transverse and perfectly straight, the median lobe small
but abrupt, prominent ; disk very densely but not coarsely punctate. Elytra
but slightly wider than the prothorax and fully twice as long, hemi elliptical,
the humeri scarcely at all prominent ; disk deeply, not very coarsely striate,

A single female. I have, however, seen another specimen in the
cabinet of Mr. Jiilicb. This is a very distinct form, easily distin-
guishable from helvinus by its larger size, more transverse and tri-
vittate prothorax, and by the alternately conspicuously squamose
elytral intervals. It closely resembles a small Limnoharis grisea.
I.I1^0]*0TIJS n. gen.
This genus is founded upon a male representative in the LeConte
cabinet, which cannot be distinguished in any way from Boheman's
Ceyitriniis distinctus, as described from Brazil ; it will include also
the Brazilian C. ivestwoodi, parallelus and other allied species.
The body is stout, rhomboidal and convex, the beak long, more
or less slender, arcuate and slightly gibbous above at base, the con-
. striction separating it from the head being in the form of a deep
transverse and extremely pronounced furrow. The mandibles are
large, prominent, non-decussate and strongly dentellate along their
inner edge. Antenna? inserted behind the middle, slender, the basal

club small, narrowly oval, pointed and with its basal joint consti-
tuting nearly one-half of the mass.
The prothorax is subtubulate at apex, the anterior coxse large,
prominent and separated by not quite their own width, the pro-
sternnm in the male having a large, oval, extremely deep median
excavation and two ante-coxal processes of great length, extending
far in advance of the head, and upwardly everted at apex. The scu-
tellum is large, slightly trapezoidal, smooth, polished, flat, entirely
unimpressed and feebly, sparsely punctulate toward base only.^

PYCHYBARIS.
LeConte— Proc. Am. Phil. Soc, XV, p. 302.
The original type is still the only known species assignable to
this distinct and somewhat isolated genus. The body is short and
very robust, feebly setose, polished and, although normally centri-
niform in pygidial structure, possesses many of the characteristics
of Onychobaris, as remarked by its author.
The beak is rather long, strongh' arcuate, with the punctures not
very dense and arranged in subimpressed series, more confused at
the sides toward base, the mandibles not in the least decussate when
closed, but coming together on the axial line as in Centrinus. The
antennae are inserted far behind the middle of the beak, with the
scrobes moderately oblique, attaining the eyes, the scape short, the
funicle gradually thick toward apex, almost continuous in outline
1 Since this was written I have received specimens of the true distinctus,
taken near Rio de Janeiro, and find that they are identical with the Texan
representative.
Coleopterological Notices, IV. C05
with the finely and densely pubescent club, the latter moderate in
size, oval, with the basal joint rather large.
The prosternum is flat, broad between the coxae, the latter sepa-
rated by their own width, the external sides of the cavities pro-
longed anteriorly for a short distance by deep and conspicuous
closed fissures, as noticeable in some other genera of the present
tribe; anteriorly, the apical constriction is totall}' obsolete, but in
its place there are the two deep and somewhat approximate fovea?,
with connecting groove, as in Onychobaris, each fovea being pro-
longed posteriorly for a short distance.
The scutellum is moderate in size, flat and almost circular. Legs
moderately robust, the tibia? rather roughly sculptured and feebly
fluted externally ; but this character is apparently not very impor-
tant from a systematic point of view, as it recurs in several other
genera, not especially related, such as Limnobaris. Tarsi robust,
with the third joint very large and deeply bilobed, the claws small,
rather slender, free and divergent.
] Pachyl>ai'is porosa Lee. — Proc. Am. Phil. Soc, XV, p. 302.
Robust, convex, polished, black, the beak, legs and antennae more
or less rufo-piceous ; vestiture very sparse, consisting of minute
scarcely distinguishable setaj on the prothorax, and longer poste-
riorly recumbent and robust setae on the elytra, where they are
piceous in color and inconspicuous, very small but whitish on tl)e
under surface. Beak slender, strongly arcuate, striato-punctate,
lully as long as the head and prothorax in the female and quite
distinctly shorter in the male, the antennae moderate, the scape
short, first joint of the funicle as long as the next four, second a
little longer than wide and slightly longer than the third. Pro-
thorax short, two-thirds wider than long, the sides broadly rounded
and strongly convergent anteriorly, feebly constricted but not
tubulate at apex, becoming nearly parallel toward base, the latter
transverse, the median lobe small, prominent and truncate, the
truncation feebly emarginate to receive the scutellum; disk rather
coarsely, deeply but not closely punctate, without impunctate line.
Elytra scarcel}' perceptibly wider than the prothorax and three-
fourths longer than the latter, not quite as long as wide; outline

JMICROCHOLIJS.
LeConte— Proc. Am. Phil. Soc, XV, p. 303.
This isolated genus is characterized by a broad, moderately con-
vex body, with normally striate elytra, an unimpressed prosternum,
non-tubulate prothorax and small tarsal claws, and differs greatly
from Oomorphidius, under which name I have separated two of
the species assigned to it by its author, in several important charac-
ters as given in the table.
The mandibles are rather long, prominent, feebly arcuate in ex-
ternal outline, scarceh^ at all or feebly decussate when closed, and
much more angulate anteriorly in this state than in Oomorphidius
and Eisonyx. In fact in this and several other ways, Microcholus
forms a tolerably satisfactory intermediate between the genera men-
tioned and Centrinus.
The two species at present known should be separated subgene-
rically as follows : —
Subgenus I.
Beak compressed toward base, minutely, feebly punctate even at the sides,
the apex flattened and siibdilated ; scutellum rather large, elongate-oval
and tumid ; elytral strife much coarser, impunctate ; tarsal claws very
stout; integuments nearly glabrous above 1 striatllS
Subgenus II.
Beak cylindrical, neither compressed toward base nor flattened at apex ;
scutellum very minute, triangular ; elytral strise fine, remotely punc-
tate; tarsal claws very small but slender; integuments rather densely
but unevenly squamose 2 ptiiicticolli^
In general outline of the body M. puncticoUis almost perfectly
resembles Simocopis amhrina Pasc. ; the beak is however quite
different.

tellum, also several widely dispersed on the elytra and a small
group at the base of the third interval ; under surface sparsely, the
legs, meso- and met-episterna and sides of the last three ventral
segments more or less densely, clothed with large white scales.
Head separated from the beak by a very feeble impression, the
beak fully as long as the prothorax, flattened near the apex and
strongly compressed toward base, strongly, evenly arcuate, sparsely,
very minutely punctate throughout and moderately stout; antennse
slender, the basal joint of the funicle slender, fully as long as the
next four, the second slender and as long as the next two, club

Florida (Lake Harney). Cab. LeConte. Represented, as far as
known, by the unique type. The upper surface in the type is not
denuded of scales as supposed by LeConte ; the punctures, other
than those very remote ones which bear the long isolated scales,
bear each an infinitesimal seta.

Florida (Baldwin). This species differs extremely from striatiis
in many important structural characters, and is the only one which
has been taken in any number. The scales are rather easily abraded.
The epistornal lobe is very short and narrow, occup3nng the median
third of the width, and limited at each side by a long deep oblique
and arcuate fissure, the apex broadly sinuate in the middle ; in stri-
aluH it is more than twice as wide, not at all advanced and is trans-
versely' truncate at apex.
]VICE]\'TRIJS n. gen.
The oblong-oval, sometimes almost cylindrical and convex form
of the body, will readily serve to distinguish the species of this
genus from those of Centrinus, where the outline is more rhom-
boidal. The beak is generally thick and rather short, differing but
slightly in the sexes, often strongly compressed or flattened at the
sides toward base, but, in contractus, becoming longer, cylindrical
and almost impunctate, at least in the female. The antennae are
inserted at about the middle in the female or slightly beyond in the
male. Mandibles rather well developed, nearly straight in external
outline, with their inner edge dentellate ; they are not decussate when
closed, the form then being anteriorly prominent in angle or ogive.
The prosternum may be either canaliculate and feebly bicarinate
along the middle or perfectly flat, sometimes flat in the female and
Coleopterological Notices, IV. 609
feebly impressed in the male, but always more or less narrowly
separates the cox£e, and the ante-coxal corneous processes of the
male, forming so characteristic a feature of Centrinus, are completely
obsolete. The scutellum, legs and abdomen are nearly as in Cen-
trinus, and the body is similarly squamose ; the mes-epimera are,
however, much less frequently visible from above in the reentrant
angle between the protliorax and elytra.
Our species are not very numerous and may be recognized a.s
follows : —
Prosternum flat or approximately so.
Anterior coxfe separated by less than one-half of their own width; Leak
moderately stout and snbequal throughout.
Squamules of the pronotum abruptly and broadly dense and conspicuous
at the sides, and sometimes, also, narrowly along the middle, the
vestiture of the intervening regions consisting of small and more or
less inconspicuous squamules.
Punctures of the pronotum contiguous and more or less longitudinally
coalescent ; scales of the elytra disposed in a single even series on
each interval 1 liiieicollis
Punctures of the pronotum rather widely separated ; elytral scales dis-
posed in one or more series on each interval, quite broadly confused
on the third and still more broadly on the fifth 2 ingenuiis
Squamules of the pronotum uniform in structure throughout and but
slightly uneven iu distribution, usually larger and gradually a little
denser toward the sides.
Anterior coxse very approximate, sejiarated by about one-fourth of their
own width or less.
Protliorax about as long as wide, coarsely, rugosely but not very
deeply sculptured ; body narrow 3 scitlllllS
Prothorax distinctly wider than long, the body more broadly oval.

Anterior cox?e smaller and separated by nearly one-half of their own
width ; very small species ; prosternum perfectly flat.

near the sides and along a narrow median line of the pronotum, and
disposed in a nearly even single line along each elytral interval ;
intermediate areas of the pronotum clothed with exceedingly minute
setiB ; scales of the under surface broadly oval and dense, except
toward the sides of the prothorax, where they are fine sparse and
subdenuded. Beak stout, moderately arcuate, varying in length
from scarcely as long as the prothorax to as long as the head and
prothorax, the antennae inserted a little beyond the middle, the basal
joint of the funicle as long as the next two, the second one-half
longer than the third, the club moderate, oval, densely pubescent,
with the basal joint much less than one-half the mass. Prasternum
not impressed, feebly, transversely constricted toward the middle
behind the apical margin, separating the anterior coxte in the male
by less than one-fifth of their own width, but in the female by
a much more appreciable distance. Length 2.3-3.5 mm. ; width
0.8-1.4 mm.
The series before me is from Massachusetts, District of Columbia
and Texas. The beak varies considerably in length, irrespective of
the usual sexual difiference, which is not remarkably pronounced,
and the elytral squanniles are sometimes distinctly shorter and
broader. I have retained the name given by LeConte to this
species, although it differs from Boheman's description of the
Mexican type in its piceous-black and not rufo-ferruginous legs, and
the statement "antenna apicem rostri propius insertie," is almost
irreconcilable. It is quite probable that there are several closely
allied species confounded here, but my material is not sufficiently
extensive to properly define them.
2 IVicentrilS ingenuus n. sp. — Oblong-oval, black and somewhat shin-
ing throughout, the legs with a feeble rufopiceous tinge; vestiture consisting
of pale yellowish scales, broad and dense beneath, elongate and narrower on
the elytra, where they are disposed in from one to two series on the intervals,
the lines of the third and fifth wider and more conspicuous ; on the pronotum
the squamules are very small, dark in color and entirely inconspicuous, except
in lateral fifth or sixth, where they become abruptly broad, denser and pale
yellowish, also visible along the median line especially toward base. Head
finely but strongly punctured, the impression very feeble, not foveate ; beak
moderately stout, cylindrical, deeply, densely punctate and subrugulose, not
quite as long as the head and prothorax, strongly, abruptly bent at base and
also strongly but more gradually arcuate toward apex ; anteuns inserted just
beyond the middle, the basal joint of the funicle unusually short, not longer
than the next two, the second much more slender than the first and fully
three-fourths as long, subequal to the next two, club about as long as the four
Coleopterological Notices, IV. 611
preceding joints combined. Prothorax one-third wider than long, the sides
feebly convergent, broadly, evenly and feebly arcuate nearly to the apex, then
gradually more strongly convergent, but not at all sinuate, to the apes, the
latter truncate and one-half as wide as the base, which is straiglit and trans-
verse, the lobe rather small but distinctly prominent ; disk with deep and
moderately large punctures, which are perforate and rather widely separated,
but somewhat unevenly distributed, the impunctate line narrow but distinct,
even and entire. Scutellum very densely squamose. Elytra slightly wider than
the prothorax and about four-fifths longer, the sides quite strongly convergent
throughout, the apex somewhat narrowly rounded ; disk rather coarsely,
deeply striate, the intervals from one-lialf to once wider than the grooves,
closely, deeply, confusedly and somewhat coarsely punctured throughout.
Abdomen densely squamose. Prosternum perfectly flat, separating the rather
large coxse by one-fifth of their own width. Length 3.8-4.0 mm. ; widtK 1.7—
1.8 mm.

This species is not closely allied to any other, although belonging-
in the neighborhood of decipiens; it differs in its much more abbre-
viated basal joint of the antennal funicle and very markedly in the
nature of the pronotal sculpture and vestiture. The type is a
female; in the male the beak is a little shorter and thicker, with
the antennsB inserted at apical two-fifths. Three specimens.
3 ZViceiltrilS SCitulus n. sp. — Elongate-oval, convex, black and shining
throughout, the legs somewhat piceous ; vestiture white, consisting of large
dense scales beneath and narrower sparsely placed squamules above, the
latter more evident toward the sides of the pronotura but not forming a defi-
nite vitta, not denser along the median line ; on the elytra they form a single
or partially double line on each interval. Head finely but deeply, rather
closely punctured, not squamose, the impression entirely obsolete ; beak
moderately thick, rather feebly, evenly arcuate, coarsely, deeply, linearly
punctate throughout at the sides and longitudinally furrowed, nearly as long
as the head and prothorax, the antennae inserted near apical two-fifths, the
scape rather long but not attaining the eye, the basal joint of the funicle as
long as the next three, the second one-half longer than the third, the club
rather small, oval, densely pubescent, about as long as the preceding four
joints combined. Prothorax very nearly as long as wide, the sides broadly,
evenly, feebly arcuate and convergent anteriorly, becoming nearly parallel in
basal two-thirds, the apical constriction completely obsolete ; apex truncate,
fully one-half as wide as the base, the latter transverse and straight, the
median lobe one-third the total width, prominent ; disk without distinct
median line, the punctures coarse, not very deep and partially coalescent,
forming longitudinal rugse. Scutellum quadrate, squamose, the apical angles
acute and prominent. Elytra a little wider than the prothorax and almost
twice as long, the humeri small but decidedly prominent, the sides behind

The sex of the sin<i;le specimen before nie is not determinablt;

consisting of slender sparse sqnamnles on tlie pronotum, larger and a little closer
toward the sides and on the median line toward base ; on the elytra broader

interval, sometimes partially double on the third, iifth and seventh toward
base ; scales of the under surface large but sparse on the abdomen, dense on
the met-episterna. Head finely, strongly, rather closely punctate, the beak

The single specimen is a female and represents a species allied to
decipiens, but differing in its much smaller size, longer elytra with
uniseriate intervals, and in many other characters.

closely punctured, the impression almost completely obsolete and with a deep
median fovea ; beak long, rather slender, cylindrical, evenly, rather strongly
arcuate, polished and almost completely impunctate except at base, where
there are also a few sqnamnles, and where the thickness becomes somewhat
greater, fully one-half as long as the body ; antennae inserted distinctly be-
yond the middle, the second funicular joint unusually elongate, more than
three-fourths as long as the first and nearly as long as the next tliree; club

than long, the sides broadly arcuate, becoming nearly parallel toward base,
strongly convergent, broadly and just visibly sinuate near the apex, the latter
tnuncate and not quite one-half as wide as the base, which is straight and
transverse, the median lobe one-fourth of the total width, prominent and
sinuato-truncate at apex ; disk somewhat coarsely, deeply, densely punctate,
the punctures tending slightly to coalesce longitudinally, the impuuctate line
narrow but almost entire. Scutellum rather large, transverse, very densely
and conspicuously albido-squamose. Elytra but little wider and about four-
fifths longer than the prothorax, scarcely longer than wide, hemi-elliptical,

slightly prominent ; disk deeply but not very coarsely striate, the intervals
flat, from two to three times as wide as the grooves and all deeply, densely

a transverse nude excavation near the apical margin, the coxae separated by
three-fifths of their own width. Length 3.2 mm. ; width 1.65 mm.
Florida.
In its longer, polished and almost impunctate beak, more elongate
second funicular joint and rather more widely distant anterior coxie,
as well as in its shorter and broader bodily form, this species is de-
cidedly aberrant; but all the remaining characters seem to coincide
with those of the present genus. The single specimen appears to
be a female, and, in the other sex, the beak is very likely shorter
and more punctate as in the group of Centrinus containing denti-
cornis, to which the species of Xicentrus bear some analogy in
other respects also.

toward base, moderately arcuate, scarcely longer than the prothorax,
coarsely, deeply but not very densely, lineately punctate and grooved,
the antennge inserted distinctly beyond the middle, the basal joint of
the funicle longer than the next two, the second three-fifths as long
as the first and as long as the succeeding two, three to seven nearly
equal and subquadrate; club small, rather narrowly oval. Prothorax

visibly wider than the prothorax, the sides feebly convergent, the
apex not very narrowly rounded ; disk finely but deeply striate, the
intervals from two to three times as wide as the grooves, rather
coarsely, moderately densely, rugosely and indistinctly punctate
throughout their widths. Prosternum deeply channeled along the
middle, the groove squamose and limited at each side by an elevated
straight ridge, the coxae separated by nearly one-third of their own
width. Length 4.6-5.0 mm.; width 1.9-2.1 mm.
Florida (Enterprise and Haw Creek). In the female the antenna?
are inserted at the middle of the beak, and the first joint of the
funicle is a little longer, the second shorter; the beak however does
not differ much from that of the male, being merely a little less
stout, somewhat less coarsely punctate and about as long as the
head and prothorax. The statements in the original description,
that the beak is slender and the anterior coxai widely separated, are
greatly misleading.
CENTRIIVITES n. gen.
The chief characters differentiating this genus from Centrinus,
are those which relate to mandibular and antennal structure, but,
although in several other respects the single species representing it
is somewhat peculiar, it cannot be denied that Centrinites is one of
the few unsatisfactory genera necessitated b}' a mandibular basis of
classification — unsatisfactory because there is not a sufficiently great
peculiarity of habitus. I believe, however, that any other taxo-
nomic basis for the genera in this part of the Barini, would give
rise to much more pronounced and wide-spread ambiguity.
The mandibles in Centrinites are nearly as in Nicentrus, very
feebly decussate and rather prominent when closed, but at the same
time quite deeply notched within near the apex. The antennae are
inserted slightly beyond the middle of the beak, and the outer joints
of the funicle are finely pubescent like the club, having also, how-
ever, the usual long bristling setae or squamules; the outer joints
do not merge gradually into the club, the latter being sensibly ab-
rupt.
The prosternum is impressed along the middle, very narrowly
separating the coxk, and the prothorax is tubulate at apex. Mes-
G16 Coleojjterological Notices, IV.
epimera slightly visible from above. Scutelluni sparsely clotlie(l
with dark-brown squamules. Pygidium completely covered, the
fifth ventral segment not as long as the two preceding together.
Met-episterna narrow. Tarsi normal, the claws moderate, free and
divergent. In some of these characters the genus is related to
Nicentrus^ but the strongly tubulate prothorax and rhomboid;il
form of the body will readily distinguish them.
1 Ceiltl'inites Strigicollis n. sp. — Rhomboid-oval, moderately stout,
convex, shining, black, the tibite, tarsi and antenn;e more or less piceous ;
vestiture consisting of elongate slender white scales and slightly smaller pice-
ous squamules, the former broadly along the sides and on the basal lobe of
the pronotum, and also on elytral intervals two, near the base and toward
ajjex, four and six broadly, and three, five and seven in single sparse lines
which are less distinct toward base and apex ; under surface rather sparsely
clothed with white scales, the met-episterna very densely so throughout.
Head finely but strongly, rather closely punctured, the transverse impression
broadly angulate but distinct ; beak somewhat stout but not much thicker
toward base, evenly, distinctly arcuate, fully as long as the head and pro-
thorax, the flattened sides deeply densely and rugosely punctate, the dorsal
surface polished and with an even series of small punctures at each side of
the impunctate line ; antennse inserted a little beyond the middle, the scape
extending three-fourths the distance thence to the eye, the basal joint of
the funicle fully as long as the next three, the second less than one-half
as long as the first and one-half longer than the third, outer joints finely
pubescent, and also coarsely setose, club finely, densely pubescent, moderate
in size, the basal joint forming nearly one-half the mass. Prothorax two-
thirds wider tlian long, the sides feebly convergent and nearly straight to
apical third, then strongly rounded to the well-marked constriction ; apex
tubulate and fully one-half as wide as the base, the latter transverse, sin-
uate at each side of the small moderately distinct median lobe ; disk
with long deep longitudinal rugse, the median line very finely carinate.
Scutellum quadrate, emarginate behind, sparsely clothed with brown squa-
mules. Elytra, distinctly wider than the protliorax and more than twice as
long, the humeri rather prominent but obtuse ; sides strongly convergent, the
a.pex somewhat narrowly rounded ; disk moderately and not very abruptly
striate, the intervals flat, about twice as wide as the grooves, the first, third,
fifth and seventh uniseriately punctate, the others confusedly so, the punctures
moderate, deep, not very dense. Prosternum with a deep squamose parallel-
sided longitudinal impression, ending behind the anterior margin in a small
transverse nude and deeper pit, the coxEe separated by one-fourth of their own
width. Length 3.5 mm. ; width 1.7 mm.
North Carolina (Hot Springs) ; Missouri.
This species bears a deceptive resemblance to Centrinun tortuosus,
but is less robust and has the pale scales arranged in rows and not
Coleopterological Notices, IV. 617
sparsely sprinkled over the elytra. Its real isolation is shown not
only by the characters which I have assumed to separate it generic-
ally, but by the very exceptional fact that the elytral intervals which
are narrowly and uniseriately punctured and pubescent, are the
third, fifth and seventh, while in the vast majority of genera these
are the more conspicuously broad and pubescent intervals. The
t\-pe appears to be a male.

LeCoiite — I'roc. Am. Phil. Soc, XV, p. 305.
This is one of the aberrant and specialized generic types so char-
acteristic of the centrinide group of Barini, and is entirely isolated
in general form of the body, as well as in tarsal structure. The
beak is rather slender and arcuate, moderate in length and cylin-
drical, although rather rapidly dilated and noticeably flattened
toward the truncate apex, and with peculiarly small, widely dis-
tant mandibles, which can apparently do little more than mutually
touch when closed ; they are strongly dentate externally near the
base. The antennae possess no exceptional features, but are slender,
with the club small and less densely pubescent than usual. The
inipres.sion separating the beak from the head is feeble and very
broad. Prothorax rather large in comparison with the elytra, sub-
equal to the latter in width or a little narrower, subcylindrieal, with
broadly rounded sides, strongly constricted at some distance behind
the apex, the latter conically tubulate. Scutellum very small and
rather deeply seated.
The prosternuni is deeply, transversely constricted at a consider-
able distance behind the i\\)ex, but not otherwise modified, unim-
pressed, the anterior coxae rather small and remote, usually sepa-
rated by fully their own width. Legs rather long and somewhat
slender, the tibise deeply sculptured and more or less ridged and
fluted, the tarsi slender, with the third joint but slightly larger than
the second, emarginate, glabrous beneath, with a small setose tuft
near each apical angle ; claws rather long, slender, free and widely
divergent.
The three species which I have been obliged to recognize may
be outlined in the following manner: —
Pronotal punctures smaller, although still comparatively coarse, denser, with
a broad, fusiform, polished, and sharply limited impunctate line, which
attains and becomes confluent with the broad apical impunctate margin.
618 Coleopterological Notices, IV.
Elytral punctures very remote, the surface almost glabrous but squamose
at the base, behind the scutellum and obliquely at the sides behind the
middle ; intervals extremely unequal in width, the strise finer and not
noticeably punctate 1 grandicollis
Elytral punctures closer and larger, more confused, the strise much coarser,
deep, distinctly punctate at the bottom ; vestiture more abundant, densely
squamose also in a sutural line behind the middle ; intervals much less
unequal in width ; size somewhat larger 2 iusignis
Pronotal punctures very coarse and not dense, with merely an elongate and
ill-defined median area, toward which they become still sparser; elytra
with an abbreviated post-scutellar spot which is covered with large white
scales 3 obsoletus
Calandriiuis appears to be peculiar to the somewhat isolated
zoological province embracing Colorado and the northern part of

Colorado. Cab. LeConte. Represented only by the unique type
from which the description is taken. This species differs from in-
signis in its smaller size, straighter and more convergent sides of
the prothorax toward base, much more uneven and more sparsely
punctate elytral intervals, and in many other characters.
2 Calandriniis insigiiis n. sp. — Ovulate, strongly convex, highly
polirihed, the head alutaceous, blackish-piceous, the legs and beak rufous ;
vestiture consisting of long rather robust hairs, yellowish in color, sparse on
the pronotum, becoming broader white denser and squaraiforui near the sides
anteriorly and at lateral sixth toward base ; on the elytra the yellowish slen-
der squainules are moderately dense toward base, becoming denser white scales
near the humeri, and also on intervals one, and four to seven, for a short dis-
tance behind the middle, the yellowish squainules elsewhere very sparse ;
under surface uniformly and rather sparsely clothed with elongate white scales.
Hmd with a distinct, rather large frontal fovea, tlie impression almost com-
pletely obsolete ; beak as long as the head and prothorax, arcuate, slender,
finely, sparsely punctate, the punctures linearly arranged along the side of
the impunctate line ; antennae nearly as in grandkolUs. Prothorax very nearly
as long as wide, the sides parallel, evenly, rather strongly arcuate in basal
four-fifths, then rounded, convergent and broadly constricted to the apex ; ba.'ee
feebly oblique and straight from the centre to each basal angle ; disk with a
wide subentire distinctly defined impunctate line, the punctures .somewhat
coarse, deep, very close but not quite in mutual contact. Elytra one-fourth
longer than wide, nearly one-half longer than the prothorax, and, at basal
fourth, a little wider than the disk of the latter, oval in form, the sides strongly
arcuate toward base, thence convergent to the narrowly rounded apex, disk
with coarse, deep, abrupt, remotely and distinctly punctate strise, the inter-
vals flat, from one-half wider than, to about twice as wide as the grooves, finely,
sparsely and more or less confusedly punctate throughout. Abdomen coarsely,
deeply puncitate. Length 3.4 mm. ; width 1.5 mm.
Colorado.
I owe the above- described type to the kindness of Mr. W. Jiilich,
in whose cabinet there is a series of several specimens. The species
is easily distinguishable from grandicollis by the characters gi\ eji
in the table, and also by the coarser striae and denser and more

confused interstitial punctuation, although the punctures tend to
form single lines on the narrower intervals. The punctuation of
the prothorax is nearly the same as in grandicoUis, but the vesti-
ture throughout the body is much more abundant and conspicuous,
and there is a sutural line of broader white scales behind the middle
in this species, which is entirely wanting and replaced by the usual
fine sparse squamules in grandicoUis.
3 CalaildrillllS obsoletlis n. sp. — Cylindro-oval, very convex, pol-
islied, piceous, the legs and beak bright rufous ; vestiture white, consisting
of elongate squamules sparsely placed on the prothorax and elytra, becoming
denser and more broadly oval on the latter toward base, especially in a broad
line behind the scutellum and toward the humeri, and also along intervals
four to six for a short distance behind the middle. Headviith a small frontal
fovea, the beak very slender, finely, sparsely punctate, as long as the head
and prothorax, strongly, evenly aicuate, the antenna slender, inserted just
behind the middle, the first funicular joint slender, as long as the next thre^-,
the second one-half as long as the first, all the joints longer than wide except
the seventh, which is a little transverse, club small, as long as the preceding
four joints combined, rather thin, sparsely pubescent and slightly shining,
with the basal joint large. Prothorax very nearly as long as wide ; sides par-
allel and broadly arcuate to apical fourth, then rounded and constricted, tlie
apex strongly subtubulate ; base broadly, evenly arcuate, the median lobe
obsolete ; disk very coarsely, deeply punctate, without distinct impunctate
line, the punctures rather uneven in size, form and distribution, but gener-
ally separated by distinctly less than their own diameters. Scutellum minute,
deeply seated. Ehjira slightly longer than wide, very slightly wider than
the prothorax and one-half longer than the latter, ovalo-conoidal, narrowly
rounded behind ; disk rather coarsely, deeply striate, the intervals fiat, from
two to three times as wide as the stri:e, each with a single line of fine distant
and inconspicuous punctures. Length 2.8 nmi. ; width 1.25 mm.
Colorado.
Readily distinguishable from grandicoUis and insignis by tlie
much coarser, sparser punctures of the pronotum, and the entire
absence of a well-defined median impunctate line, the punctures
simply becoming sparser at the middle ; the apical margin is, how-
ever, broadly impunctate, as in the species mentioned. A single
specimen.
CEKTRINOGYXA n. gen.
The two species which are referred to this interesting genus, are
the most remarkable of the tribe in their wonderful sexual divergen-
cies at the apex of the abdomen. In the male, the pygidium is
Coleopterological Notices, IV. C21
large, vertical, strongly convex and completely exposed, while in
the female it is entirely covered, with the exception of a very small
and barely distinguishaljle portion at the apex. In other words,
assuming the division adopted by LeConte, which is still, without
much doubt, the best that can be devised, the male is a normal
baride, while the female is an equally pronounced centrin'ide. This
of course destroys any idea of two perfectly isolated natural groups,
and compels us to treat the genera as forming part of a single well-
defined series. In fact the homogeneity of the entire tribe is proved
by repeated parallelisms of structure throughout.
In Centrinogyna the body is elongate, parallel and somewhat
depressed, nearly as in aiany species of Limnobaris. The beak is
rather slender, arcuate, about as long as the prothorax, with the
antennae inserted distinctly beyond the middle, slender, moderate
in length, the first funicular joint as long as the next four, the
second slightly elongate but less than one-half as long as the first,
the club oval, abrupt, densely pubescent and with the basal joint
constituting ver}" nearly one-half of the mass. Mandibles deeply
notched within, acute, not noticeably overlapping when closed and
then formiug a prominent angle.
The prosternum is perfectly unimpressed, having the usual deep
transverse constriction behind the apex but not otherwise modified,
the anterior coxa? not very widely distant and separated by but
slightly more than one-half of their own width, the prosternal pro-
cess terminating midway of their length in a distinct transverse
suture ; behind this, the prosternum is but slightly produced, pass-
ing for only a short distance over the edge of the mesosternum,
with the apex broadly and feebly sinuate in "the middle. The pro-
thorax is strongly tubulate at apex. Scutellum very small, sub-
quadrate or a little longer than wide. Legs normal ; tibiae nearly
smooth, the tarsal claws well developed, stout, free and divergent.
Yestiture throughout consisting of very sparse slender setiform
squamules, white in color and arranged in a single somewhat
uneven semi-erect and bristling line on each of the elytral intervals.
This genus offers a good example of the polarity theory in the dis-
tribution of secondary sexual characters, advanced by Dr. LeConte,
the beak and antennae being quite devoid of any perceptible sexual
diflerences, while those at the apex of the abdomen are exception-
ally pronounced. The theory does HOt hold so well, however, in
some other genera, as for example in several species of Oxytelus
622 Coleopterological Notices, IV.
which I have in mind, and fails completely in Conopvoctus Lac. of
the present tribe, where the sexual differences in the form of the
beak, point of antennal insertion and structure of the pygidium,
become extreme in C ^-pw«<(//oi(fs Fab., as before described under
the genus Madarellus.
The species may be thus distinguished: —
Piceons ; legs rufous ; seta? long and conspicuous ; pronotuni .strongly and
longitudinally strigose 1 strigata
Black throughout, subglabrous, the setse extremely sparse and short; pro-
notuni more finely punctate, the punctures distinct, sometimes feebly
coalescent longitudinally 2 procera
1 Centrinogyiia strigata Lee. — Proc. Am. Phil. Soc, XV, p. 421
(Centrinus).
The original description of what LeConte designates a remark-
able species from an inspection of the female alone, is well given
and ample for purposes of recognition, except that the anterior coxse
are only separated by about three-fifths of their own width. The
beak is rather slender, evenly, moderately arcuate and does not differ
appreciably in the sexes ; it is sparsely punctured and has a very
even line of small punctures along each side of the median impunc-
tate line. The prothorax is very nearly as long as wide, parallel
and feebly arcuate at the sides and abruptly, broadly and strongly
tubulated at apex, the base transverse, the median lobe very small
and almost obsolete; disk with longitudinally, closely, unevenly
and deeply plicate or rugose sculpture, the impunctate line very dis-
tinctly defined, polished and somewhat elevated. The elytral striiB
are moderately coarse, deep and abrupt, impunctate, the intervals
flat, nearly three times as wide as the grooves, each with a single
somewhat uneven series of rather small but deep, approximate
punctures. Length 3.5-4.8 mm.; width L2-1.7 mm.
Colorado and Wyoming. Taken in abundance by Mr. Wickham
at Greele}'^ and Laramie.
2 Centrinogyiia procera n. sp. — Elongate, parallel, moderately con-
vex, shining, black throughout, the vestiture consisting of very small setiform
squamules, which are exceedingly sparse and inconspicuous but more evident
at the sides of the pronotuni and last three ventral segments, and near the
apex of the met-episterna. Head minutely, sparsely punctured, the trans-
verse impression strong, broadly angulate in profile ; beak rather thick, sub-
cylindrical, evenly, ratlier feebly arcuate, as long as the prothorax, hardly
differing in the sexes, but a little thicker and more punctate in the male, the
Coleopterological Notices, IV. 628
punctures ratlier fine, lineate dorsally but larger denser and confused at the
sides ; anteunse inserted near apical third, the scape long, first funicular joint
as long as the next three, the second small, obconical, slightly longer than
wide and about one-half longer than the third, outer joints transverse, club
moderate, densely pubescent, the basal joint constituting more than one-half
the mass and more sparsely pubescent near the base. Prothorax about as long as
wide ; sides parallel, evenly and broadly arcuate to apical sixth, then abruptly
rounded to the deep constriction ; the apex strongly tubulate, three-fourths as
wide as the base, the latter transversely truncate, the median lobe small and
feebly rounded ; disk with a narrow distinct and entire impunctate line, the
punctures rather fine but deep, uneven, not densely crowded, well separated
transversely but tending slightly to longitudinal elongation or partial coales-
cence. Scutellum very small, quadrate, glabrous. EUjira equal in width to
the prothorax and fully twice as long, the sides parallel, feebly convergent in
apical third, the apex rather abruptly and not narrowly rounded; humeral
callus almost obsolete ; disk with moderately deep striae, which become finer
toward apex and coarser near the base ; intervals nearly three times as wide as
the grooves, each with a single series of rather small, uneven, approximate
punctures, somewhat confused on the third. Legs short, the anterior and
middle femora very robust, the posterior far less so. Length 4.0-4.7 mm. ;
width 1.3-1.7 mm.
California (San Francisco). Mr. Dunn.
In this species the pygicliuni of the male is large, broad, vertical,
convex, moderately densely punctate, and completely exposed ; in
the female it is entirely covered by the elytra, with the exception of
a scarcely visible fine lower margin. The prosternum is flat and
the anterior coxae separated by three-fourths of their own width.
The male appears to be much less abundant than the female in both
of these species. Five specimens.
LIMIVOBARIS.
Bedel— Fne. Col. Bas. Seine, VI, p. 183.
The mandibles in this genus are of a completely different type
from those of Ceutrinus, for, instead of being prominent, perfectly
non-decussate and totally devoid of internal inequality, they are
here short, stout, strongly arcuate, deeply notched at apex and
broadly decussate when closed, the anterior outline then being
broadly, feebly arcuate and not in the least prominent. With this
radical difference of structure, there is also a decided peculiarity of
facies, the species of Liranobaris being narrow, parallel or oval,
generally distinctly depressed, with feebly developed humeral callus
and more or less glabrous integuments. Of the genera with promi-
624 Coleopterological Notices, IV.
iient mandibles, the closest ally of Limnobaris appears to be Cen-
trinogyna, and, in this connection, it should be stated that in the
former the tip of the pygidium is occasionally exposed, especially
in the male.
The basal joint of the antennal funicle is generally long, the
second decidedly short, becoming longer in the fifth group, and the
club varies considerably, being moderately robust, with a large basal
joint in the first group, but narrower and with a much shorter basal
joint in the others. There is also considerable variation in the
amplitude of the prosternal process between the coxae, the latter
being generally more or less remote, but occasionally narrowly
separated, again demonstrating the slight w^eight of prosternal
characters in some parts of the centrinide series. The prosternum
is usually flat, but in some species may be flat in the female and
deeply excavated in the male, and, in longula, is narrowl}^ impressed
along the middle in both sexes.
The beak varies in structure to a noticeable extent in the several
subgeneric groups as detailed below, and in some of these sections,
the prosternal processes of the male are iavariabl}'^ wanting, while
in others they may or may not be present. In several species,
which happen to belong to all of the subgenera except the first, the
beak varies perceptibly in length in different individuals, necessitat-
ing some caution in separating the species. I have observed this
variation in length in pi^olixa, 7'ectirost.ris, ebena, and possibly
seminitens, also, as before stated, in Nicentrus lineicoUis.
The five sections, into which it is convenient to separate our
species, may be outlined as follows: —
Antenna! club more robust, with the basal joint large, constituting more than
one-half of the ma.-s and frequently more sparsely pubescent and sliining
toward base ; beak generally thicker, more strongly and evenly arcuate
and not tumid at base, the antennae inserted distinctly beyond the middle
in the male but more medially in the female ; prosternum always widely
separating the coxae and never armed in the male ; punctuation deeper,
denser and more uneven as a rule, the vestiture frequently more con-
spicuous and always uneven ; bo.Jy usually more or less rufo-piceous in
color and noticeably depressed I
Antennal club generally narrower, densely pubescent throughout, the basal
joint much shorter ; body always intense black throughout, except in
the next subdivision, occasionally somewhat depressed.
Body oblong, moderately convex, densely, confusedly punctate and densely
but unevenly clothed throughout with oval whitish scales ; beak as in
the preceding section ; antennal club strongly annulate, the basal joint
Coleopferological Notices, IV. 625
constituting scarcely more than one-third of the mass ; anterior coxae
widely separated, the prosternum tiat, not armed in the male II
Body more or less oblong-oval, subglabrous, the beak extremely slender,
sometimes nearly straight, tumid above at base, the transverse constric-
tion distinct ; prosternum generally armed or otherwise modified before
the coxae in the male ; second funicular joint short Ill
Body narrow and linear, subglabrous ; beak very slender, not tumid at
base; prosternum armed in the male, the processes sometimes extremely
developed; second funicular joint short ; anterior coxae rather narrowly
separated IV
Body moderately dilated, convex, subglabrous except in lonyula ; beak
thicker, not at all tumid at base, the transverse impression completely
obsolete, represented by a frontal fovea ; prosternum never armed in the
male ; anterior coxae rather narrowly separated ; second funicular joint
long V

The single type is apparently a female. This species belongs in
the neighborhood of punctiger, but is not at all closely allied to it.
I have before me a specimen from Colorado which is possibly con-
specific; it has the interstitial punctures coarser, the squamose
border narrower and the elytra rufescent.

Somewhat allied to limbifer, but differing greatly in its more
depressed form and much finer sculpture, the scales at the sides of
the pronotum are not broad as in the species mentioned, and form a

than long. Elytra but slightly wider than the prothorax and three-fifths
longer, the sides rather strongly convergent and broadly feebly arcuate, the
apex evenly, not broadly rounded ; humeri not prominent ; strife very coarse,
deep ; intervals just noticeably wider than the grooves, each with a single
series of coarse, deep, close-set punctures, uneven in size, often slightly elon-
gate and frequently anastomosing. Abdomen strongly but not very coarsely or
densely punctate. Prosterfium flat, separating the coxfe by a little more than
their own width. Length 2.8 mm. ; width 1.15 mm.

The single specimen appears to be a male, and the species some-
what resembles deplanata, differing in its distinctly narrower form,
much smaller pronotal punctures and longer, more conspicuous dorsal
vestiture, as well as the characters given in the table.

Iowa (Keokuk).
The single specimen, apparently a male, represents a species en-
tirely distinct from any other here described ia its more depressed
form and coarse sculpture, and especially in the distinctly concave
elytral intervals. From fabida, which it more closely resembles, it
may be known by the shorter, less conspicuous vestiture, more slen-
der beak and very much coarser sculpture of the pronotum. There
are, judging by material which has been recently sent me, apparently
a number of species in our Central States allied to deplanata and
kibida, and their separation will prove to be a problem of some
difficulty.

Texas. Cab. LeConte. Represented by the unique type, which
is in a rather poor state of preservation, being much rubbed ; it is
apparent, however, from broken fragments, that the elytral scales
are normally quite distinct, and that there are some scattered scales
toward the sides of the pronotum.

This species is not at all closely related to any other ; it is repre-
sented by a single male. The si.xth funicular joint is longer than
either the fifth or seventh, and the club is unusually small.

Texas.
The sing-le specimen appears to be a female, the basal parts of
the abdomen being entirely unmodified, but as the male impression
is generally very slight indeed in this genus, it is not possible to be
entirely certain of the se.x, especially in consideration of the short
beak.

This species is not closely allied to any other and appears to form
one of the transitions from the species with stout beaks and remote
anterior coxae, to those with very slender straight beaks and more
narrowly separated coxa;. The unique specimen is a female.
11 L.iinno'baris secllisa n. sp. — Oval, moderately stout, rather feebly,
evenly convex above, shining, piceous, the legs rufous ; vestiture very uneven,
consisting, on the pronotum, of large broad and pale scales toward the sides
and before the scutellum, the scales becoming narrower and posteriorly oblique
anteriorly and toward the middle, elsewhere dark in color, smaller and incon-
spicuous ; on the elytra the large pale scales form a short line on the third
interval behind the middle, and several small spots along the base, elsewhere
narrow, elongate, darker and of different sizes from very minute setae to con-
spicuous scales ; on the under surface they are elongate and rather sparse
tliroughout. Head almost completely impunctate but minutely granulato-
reticulate, the impression distinct ; beak cylindrical, rather stout toward base,
evenly, feebly arcuate, with bristling scales just before the eyes, a little longer
than the head and prothorax in the female, but not quite as long as the pro-
thorax in the male, rather coarsely, sublinearly punctate ; antennae inserted
at the middle in the female or distinctly beyond in the male, the basal joint

The general characters of the abov^e description are drawn from
the female ; in the single very small male before me, the prothorax
is quite distinctly wider than long, with the apex three-fifths as wide
as the base. The great disparity in the length of the beak is, how-
ever, the only very prominent sexual difference. In certain general
characters of sculpture and vestiture, seclvsa makes an excellent
transition from the normal forms of this subgenus to grisea.

12 L.iinno'baris grisea Lee. — Proc. Am. Phil. Soc, XV, p. 312 (Cen-
trinus).
Oblong-oval, moderately convex, piceous-black, the elytra and
legs rufous; vestiture consisting of large elongate-oval yellowish-
white scales, not contiguous beneath except in anterior two-thirds
of the met-episterna; on the pronotum they are still more elongate,
denser near the sides and finest and sparsest at lateral fourth ; on the
elytra they are broadly oval and unevenly disposed in strongly
marked lines along the intervals, the line of the third interval
being especially wide and conspicuous. Head glabrous, minutely,
sparsely and feebly punctate, the impression very feeble ; beak
cylindrical, rather stout, evenly and rather strongly arcuate, as
long as the head and prothorax in the female, but only as long as
the latter in the male, the basal joint of the funicle as long as the
next four together, the second as long as the next two, outer joints
very short and transverse ; club in the male large, densely pubes-
cent, as long as the six preceding joints together, oval, pointed, the
rings decreasing abruptly in transverse diameter, the basal joint
much less than one-half the mass. Prothorax coarsely, closely
punctate, two-thirds wider than long, the sides subparallel in basal
two-thirds, then strongly rounded and rapidly convergent but not-
distinctly constricted to the apex, basal angles obtuse, the mes-
epimera strongly exposed from above. Scutellum rather large,
quadrate, glabrous, but indented and setose at each side. Elytra a
little wider than the prothorax and about twice as long, hemi-ellip-
tical in outline, the strife fine, the intervals strongly, confusedly
punctate and from two to more than three times as wide as the
grooves. Length 3.4 mm.; width 1.65 mm.
The three specimens before me are from Arizona and New Jersey ;
it was originally described from Texas. In the female the antennal
Coleopterological Notices, IV. G37
club is notably smaller than in the male, and the funicle is longer
and more slender, but aside from the shorter beak of the male I do
not observe any other sexual differences.

Oblong-oval, subdepressed, alutaceous, black throughout, the
antennae slightly paler ; integuments subglabrous, the vestiture
consisting of very small fine white squamules, sparsely disposed
above and beneath. Beak in the male rather stout, cylindrical,
finely, densely punctured and squamulose toward base, straight in
basal two-thirds, then bent, scarcely more than three-fourths as long
as the prothorax, theantennaj inserted distinctly beyond the middle,
the basal joint of the funicle robust, not as long as the next three,
the second small, obconical, one-half longer than wide, the club
moderately stout, oval, densely pubescent and nearly as long as
the preceding five joints combined. Prothorax slightly wider than
long, sides parallel and feebly arcuate, rounded convergent and con-
stricted toward apex, the latter one-half as wide as the base; punc-
tures fine, not very close-set, the impunctate line distinct. Elytra
a little wider and three-fourths longer than the prothorax, hemi-
elliptical, the humeral callus large but feeble; stria? fine, the inter-
vals flat, wide, finely and more or less confusedly punctate. Pro-
sternum separating the coxae by two-thirds of their own width or
less, with two slender slightly contorted ante-coxal spiniform pro-
cesses, which are very oblique, and immediately before which there
is a large deep excavation. In the female the beak is more slender,
more evenly and distinctly arcuate, smooth, polished and evidently
punctured only near the base, not longer than in the male, being
about three- fourths as long as the prothorax ; the prosternum is flat
and the intercoxal process is not noticeably wider than in the male.
Length 2.7-3.5 mm.; width 1.1-1.5 mm.
In the description of Boheman, the beak is said to be as long as
the prothorax in the italicized diagnosis, but as long as the head
and prothorax in the description which follows, the fact being, if I
have correctly identified the species, that it is much shorter than
the prothorax in both sexes. In the description referred to I cannot
comprehend the allusion to a " pygidium."
The material before me includes series from Florida. North

Carolina, New York, Indiana, Nebraska and Colorado, some being
smaller, others larger, some with the male prosternal spines short,
others so long as to nearly attain the anterior margin. The want
of any accurate definition of the species deters me, however, from
further investigation of these forms, although from the constantly
small size and less developed aute-coxal processes of several good
series, collected in definite localities, it is possible that two or three
species or subspecies may be commingled. This species is said to
occur in California (Mann. Bull. Mosc, 1843, 2d, 293), but I have
not seen any specimens from that region.

One female example. This species is allied to coiifinis, but is
more robust, with a longer beak in the female, more widely sepa-
rated anterior coxte and more distinct squamules.
With the type I associate a male and female from Indiana, which
Coleopterological Notices, IV. 639
differ only in being a little less robust and less polished, with the
beak in the female not longer than the head and prothorax, and, in
the male, distinctly shorter than the latter, this sex having two long
slender prosternal processes.

This species bears an extreme resemblance to confinis, being
identical in sculpture and vestiture, but the ante-coxal processes
are much more developed, the elytra relatively wider and longer,
the second joint of the antennal funicle more elongate, and the pro-
sternum differs radically in having a large extremely deep median
excavation. A single male, without definite indication of locality,
but in all probability from the region indicated.

The four specimens before me are from New York, Virginia, Iowa
and Texas, the latter being the only female. In this sex the beak
is very slender, cylindrical, nearh' straight, as long as the head and
prothorax, and the antennos are longer and with a more slender club,
but, as the elytral punctures are not by any means so distinct as in
the northern specimens, it may not actually belong to this species.

men feebly, not closely punctured. Prosternum broadly, very feebly impressed
along the middle, witli a small feeble subtransverse fovea behind the apex, the
sides of the longitudinal impression slightly prominent in the form of a low
obtuse ridge for a short distance before each coxa, but without trace of ante-
coxal cusp, the coxse separated by slightly less than one-half of their own

District of Columbia. Mr. Jiilich.
The above description is drawn from the male. In the female
the beak is slightly more slender very feebly arcuate and as long as
the head and prothorax, with the auteunaj inserted at or just behind
the middle. The antennte arc longer and more slender, the second
funicular joint almost as long as the next two, and the prosternum
is perfecth^ fiat, separating the coxie by fully three-fourths of their
own width. Goncurrens is allied to conjinis, but differs in its
much longer beak, especially in the male, and by its narrower an-
tenaal club. Numerous examples.

The three specimens before me are males, the abdomen having-
a small elongate-oval and rather deep subbasal impression. The
species is related to confusa, but differs in its small size, uniseriate
elytral intervals, simple male prosternum and slightly longer beak.
From covfinU it differs in its broader, more depressed form, much
coarser elytral striae and larger, more close-set serial punctures.

Nebraska.
Not closely allied to any other species known to me, and repre-
sented by a single specimen which is undoubtedly the female, although
the abdomen has a small feeble subbasal impression, and the fifth
segment a small rounded indentation. A specimen in ni}^ cabinet
from Florida also belongs apparently to this species, but is larger
and with a much longer beak.

before each coxa, a slender process which is much more developed
than in an}' other of our apygidiate Barini, projecting very nearly
as far beyond the apical margin of the prosternum as the distance
between the latter and the coxte, the apices diverging horizontally
toward apex in order not to interfere with lateral movements of the
beak ; coxre separated by nearly one-third of their own width.

Illinois and Michigan. I also associate with this species a num-
ber of specimens taken by Mr. Wickham at Greeley, Colorado,
which seem to be merely a little smaller in size; in the single male,
however, the prosternal spines are very much shorter, only project-
ing as far as the anterior margin. I do not notice the bronzy lustre
mentioned by LeConte.

elongate and very feeble impression ; it is however a female, as is
conclusively shown by the polished, almost impunctate beak ; the
impression is spurious, and has very nearly misled me in several
species of genera allied to this. There are but two examples known
to me, and the Florida specimen in my cabinet is a male, a little
larger than the Texas type, intense black throughout, the beak
short, rather thick, cylindrical, densely, deeply lineato-punctate,
evenly, feebly arcuate and distinctly shorter than the prothorax, the
antenna? being inserted at apical two-fifths; otherwise the two
specimens seem to agree very well indeed, except that the male
is a little stouter and with less elongate elytra, rather the reverse
of what might be expected.

before me the beak is a little longer than the prothorax, with the
frontal fovea much more feeble, the body more slender and the pro-
sternum perfectly flat along the middle, l)at they are otherwise so
similar to the form which I regard as typical, that I hesitate to
describe them under a separate name.

Pennsylvania, Georgia and Florida. The male has a small elon-
gate-oval feeble impression near the base of the abdomen. In the
original type the sides of the prothorax are parallel and almost per-
fectly straight nearly to apical third, Init in other specimens they
are slightly convergent and strongly arcuate; in the Pennsylvania
male the legs are black and the interstitial punctures coarse, while
in another exami)le the legs are red and the punctures finer. The
description is drawn from the type specimen.

OLIGOLOCHUS n. gen.
The single species referred to this genus, greatly resembles Micro-
cholus atriatuH in its general features of form, sculpture and vesti-
ture, although much smaller in point of size, and would have been
referred to Microchokis were it not for the distinctly different struc-
ture of the mandibles, which are not large and prominent as in that
genus, but very small, thick, strongly arcuate, notched at apex and
broadly decussate when closed.
The principal generic characters have been given in the table, and
those of minor importance are referred to in the description of the
single species given below. Oligolochus does not resemble Zygo-
baris either in habitus or structure.

(Zygobaris ?).
Oval, moderately and evenly convex, polished, black, the legs
rufous ; vestiture very sparse and uneven, white, consisting of large
scattered scales towards the sides of the pronotum and on the median
line before the scutellum, also on the elytra toward the base of the
third and fifth intervals and a few widely scattered on the disk
toward the sides, the latter smaller and narrower ; on the under
surface sparse but more evident on the sternal parapleural ; all other
punctures of the upper surface bearing extremely minute seta?.
Beak moderately slender, evenly, not very strongly arcuate, coarsely,
sparsely, unevenly punctate at the sides, as long as the prothorax,
feebly thickened toward base and slightly flattened toward apex,
the basal impression extremely feeble ; antennce inserted a little
beyond the middle, the scape almost attaining the e3"e, the first
funicular joint longer than the next three, the second small, slightly
longer than the third ; club moderate, abrupt, oval, densely pubes-
cent, as long as the preceding four joints, with the basal joint one-
half of the whole. Prothorax one-third wider than long, the sides
very feebly convergent and distinctly arcuate from the base to the
well-marked subapical constriction, the apex not tubulate, three-
fifths as wide as the base, the median lobe of the latter small and
feeble ; impunctate line entire ; punctures coarse, not dense. Scutel-
lum very small, quadrate, impressed behind, glabrous. Elytra but
slightly longer than wide, a little wider than the prothorax and
three-fourths longer, hemi-elliptical, the apex narrowly subtruncate;

to two times wider than the grooves, each with an uneven single
series of small, not very close-set punctures, more confused on
the third. Abdomen closely, rather coarsely punctate, the fifth
segment not as long as the two preceding, the pygidium slightly
exposed at tip in the male. Length 2.3 mm.; width 1.2 mm.
Florida (Enterprise). Cab. LeConte. Represented by the unique
male type. The presternum is flat, the subapical constriction fine,
even and continuous entirely across the surface and not obsolete at
the middle as stated by LeConte ; the surface between the constric-
tion and the apex being rather strongly reflexed over the basal part
of the head, the author quoted quite pardonably mistook the groove
for the apical margin. The anterior coxte are separated by dis-
tinctly less than one-half (jf their own width. The legs are more
slender than in 3Iicrocholus striatus, but the tarsal claws are very
nearly similar, thick and approximate, though divergent and free at
base.
IDIOSTETHUS n. gen.
This genus, though related to Stethobaris, is conspicuously dis-
tinct in antennal and pectoral structure, as well as in the general
nature of the sculpture and vestiture. The antenna have the
second funicular joint elongate when compared with that of Stetho-
baris, and the club is generally smaller than in that genus; the club
varies, however, quite remarkably in size and structure.
The prosternum is noticeably tumid, especially before the coxjb,
reminding us in this respect of Orthoris, and the narrow, deep but
not abruptly defined median canaiiculation is formed in much the
same manner, as a depression between the ante-coxal prominences.
The coxiE are much more approximate than in Stethobaris, never
being separated by more, and generally by less, than one-third of
their own width. The pronotal sculpture is always in greater or
less part longitudinally rugulose, and the vestiture con.sists of small
sparse slender and recumbent seta? and squamules, the latter, in one
of the species, widely dispersed over the elytra; they are generally,
but not always, more distinct toward the sides of the body beneath,
occasionally becoming conspicuously dense.
In the short tubulate prothorax, structure of the beak, mandibles
and transverse frontal impression, scutellum, legs and tarsi, Idio-
stethus closely resembles Stethobaris, but the body is more elongate-
C50 Coleopterological Notices, IV.
oval, with less prominent and especiall}^ less post-basal humeri, and
the small, slender tarsal claws are more widely divergent.
The four representatives here recognized may be easily identified
from the following characters, the species being more isolated among
themselves than in Stethobaris : —
Elytra without dispersed sqnamules, the anteniial scape more abruptly clavate.
Antenuse with the first funicular joint not longer than the next three to-
gether ; club smaller, with its basal joint constituting about one-half of
the mass ; vestiture not dense at the sides beneath.
Sculpture coarse, the pronotum with a narrow, impunctate and generally
subcarinate line ; interstitial punctures of the elytra coarse and deep ;
larger species 1 tul>lllatll8
Sculpture finer, the pronotum very finely, densely rugulose and without
median line ; interstitial punctures smaller, rather indefinite and feeble ;
much smaller species 2 subcal'VUS
Antennae with the first funicular joint as long as the next four ; club larger,
elongate, nearly as long as the jireceding six joints combined and with its
basal joint constituting but slightly more than one-third of the mass ; vesti-

uneven, consisting, on the pronotum, of extremely minute set^ which hecome
long slender recumbent whitish squamules in lateral fifth, and in the middle
before the scutellum, also with a few widely dispersed over the intermediate
regions ; on the elytra there is a single series of very small setae on each
interval, with long slender squamules very widely dispersed over the entire
surface ; on the under surface the squamules are denser and somewhat brist-
ling on the presternum especially behind, and the smaller white recumbent
scales are sparse throughout, but denser on the met-episterna and toward the
sides of the last four ventral segments. Head finely, rather sparsely punc-
tate, the beak moderately stout, densely punctate and sparsely squamulose
along the sides, evenly, distinctly arcuate and equal in length to the protho-
rax in the male; antennae inserted near apical two-fifths, the scape rather
long and strongly, gradually clavate. Prothorax three-fourths wider than
long, the sides feebly but distinctly convergent and nearly straight to apical
fourth, then strongly rounded to the apical constriction, the apex briefly
tubulate, rather more than one-half as wide as the base, the latter broadly,
feebly arcuate, the median lobe very small and feeble ; disk very unevenly,
moderately coarsely and deeply sculptured, the impunctate line narrow but
entire, well defined and somewhat elevated; sculpture longitudinally rugu-
lose toward the middle, closely punctate toward the sides, and more finely and
very sparsely punctate at lateral fourth toward base. Scutellum minute,
quadrate, feebly impressed. Elytra hemi-elliptical, fully one-fifth wider than
the prothorax and much more than twice as long ; sides feebly sinuate toward
apex, the latter narrowly rounded ; humeri not distinctly prominent ; disk
with extremely coarse, deep, abrupt and even striae, the intervals flat, equal,
but slightly wider than the grooves, each with a single feebly impressed line
of somewhat coarse close-set rounded punctures. Prosternura decidedly tumid
with reference to the mesosternum, narrowly, strongly impressed along the
middle, separating the coxae by barely one-third of their width, and, behind
them, declivous to the surface of the mesosternum, extending somewhat over
the latter. Abdomen coarsely, very deeply, rather closely punctured near the
base. Length 3.3 mm. ; width 1.75 mm.
Alabama.
The single specimen is a male, the abdomen having a rather
small but deep subbasal impression. This species is not at all
closely allied to tubulatus, and has the anterior coxae slightly less
narrowly separated.
STJBTHOBARIS.
LeConte— Proc. Am. Phil. Soc, XV, p. 302.
The essential characters distinguishing this genus from others,
more closely allied to it in the present section of the tribe, are the
large antennal club, nearly as long as the entire funicle and resem-
bling that of Rhoptobaris, the small, slender, free but feebly diver-
654 Coleopterological Notices, IV.
gent daws, deeply, abruptly and broadly excavated presternum,
not very widely separating the coxae, peculiar oval, thick and con-
vex form of the body, with prominent humeri situated at quite a
noticeable distance behind the base, and the polished black integu-
ments, Avhieh are practically entirely glabrous, each puncture bear-
ing an excessively minute seta, only visible under considerable
amplification. Stethobaris is one of the genera connecting the
more normal forms of the tribe with the aberrant Oomorphidius
and Eisonyx.
The beak is separated from the head by a feeble but distinctly
marked transverse in]pression and is strongly arcuate, moderate in
length and thickness, and nearly always noticeably tapering from
base to apex, with the antennal scrobes strongly oblique and broadly
confluent beneath ; the mandibles are short, arcuate and broadly
decussate. The tibixe are deeply and longitudinally sculptured.
The species of Stethobaris are moderately numerous, and, with
one exception, more than usually homogeneous in external appear-
ance. It is possible, however, that they may be recognized by the
characters given in the following table: —
Integuments more or less finely and sparsely punctate, the interstitial punc-
tures of the elytra very minute and sparse.
Sides of the prothorax broadly arcuate, becoming parallel in basal half;
pronotal punctures minute and very sparse, becoming larger but not at
all confluent at the sides beneath 1 corpulenta
Sides convergent from the basal angles, the prothorax smaller and more
conical, less sparsely and more conspicuously punctured.
Prothorax with a distinct but narrow subentire impunctate line ; punc-
tures of the elytra confused, at least on the wider intervals ; sides
of the prothorax beneath obliquely and finely rugose ; last ventral
segment in both sexes distinctly shorter than the two preceding
together.
Elytral grooves very coarse, strongly, remotely punctured, the edges
feebly but distinctly serrato-crenulate ; form stouter, the prothorax
a little more transverse 2 incoiupta
Elytral grooves less coarse, much more finely punctate at the bottom,
the edges never serrato-crenulate, except occasionally very feebly so
near the base 3 OTata.
Prothorax more conical and more densely punctate, never with a clearly
defined entire impunctate line, the punctures beneath at the sides dis-
tinct, not forming elongate rugse ; elytral strije very coarse and remotely
but conspicuously punctured, the extremely minute interstitial punc-
tures forming a single line on each 4 congei'Iliaiia
Integuments coarsely, densely punctured, the punctures of the elytra forming
a single deep coarse and confluent line on each interval 5 egregia

throughout, the antennae with the first funicular joint nearly as
long as the next four, second to seventh equal in length, the former
not as long as wide ; club large, evenly elliptical, densely pubes-
cent, equal in length to the six preceding joints combined and
equally trisected by the first and second sutures. The prothorax
is short, four- fifths wider than long, the sides very strongly, evenly
arcuate, convergent anteriorly to the strong apical tubulation, and
becoming gradually parallel in about basal half, the apex not quite
one-half as wide as the base, the latter broadly, feebly arcuate, the
median lobe small but prominent, truncate ; disk sparsely, uniformly,
very finely and rather feebly punctate, coarsely but not confluently
so beneath, the impunctate line narrow, distinct and subentirc.
Scutellum a little longer than wide, impressed toward apex, quad-
rangular. Elytra, at a short distance behind the apex, fully one-
fifth wider than the prothorax, a little more than twice as long as
the latter, the humeri obtusely prominent ; outline hemi-elliptical ;

crenulate toward base ; intervals from two to three times as wide
as the grooves, minutely, feebly, sparsely and confusedl\^ punctate.

2 Stetliobaris incoiupta n. sp.— Oval, sti-ongly convex, somewhat
robust, black, glabrous and strongly shining throughout. Head finely but
strongly, sparsely punctate, the beak densely punctured at the sides, evenly,
strongly arcuate, moderately slender, distinctly tapering from base to apex
and equal in length to the head and prothorax, the antenuc-B inserted at basal
two-fifths, nearly as in corpulenta, but with the first funicular joint a little
shorter and the club distinctly longer, equalling the entire funiele excepting
one-half of the basal joint, with its first joint a little hunger than the second.
Prothorax about four-fifths wider than long, the sides feebly but noticeably
convergent and nearly straight to the middle, then gradually, broadly rounded,
becoming strongly convergent to the apical tubule, which is distinctly less
than one-half as wide as the very broadly, feebly arcuate base ; median lobe
of the latter small but distinct, truncate ; disk rather finely but deeply, not
very densely punctate, with a narrow impunctate median line, the punctures
coarser, and forming long oblique rugae beneath. Scutellum minute, quadrate,
scarcely impressed. Elytra, at a little behind the base, barely one-fifth wider
than the prothorax, nearly two and one-half times longer than the latter ;

humeri obtusely prouaiueut ; outline behind them hemi-elliptical ; stride rather
coarse, deep, remotely, distinctly serrato-crenulate, the intervals differing
greatly in width, the third twice as wide as the grooves, the fourth but slightly
wider than the latter, flat, minutely but deeply and distinctly punctate, the
punctures confused, sparse but becoming closer toward base, forming nearly
even single lines on the narrow intervals. Length 3.1 mm. ; width 1.65 mm.
Florida.
This species differs from corpulenia in its less obese form and
larger antennal club, smaller and quite differently shaped, slightly
more conical, much more coarsely, deeply and less sparsely punctate
prothorax, with the punctures not isolated beneath at the sides, but
forming long ruga? ; also in its flatter, still more unequal and less
polished elytral intervals, with the punctures less minute, deeper
and becoming denser toward base ; and finally, and quite remark-
ably, in the form of the mes-epimera, which in corpulenta are
gradually pointed upward, but much more truncate and rounded
in incompta. The present species is closely allied to ovata, and
agrees with that species in all the characters given above to distin-
guish it from corpulenta. It is represented by a single female.

ZAGLYPTUS.
LeConte— Proc. Am. Phil. Soc, XV, p. 23G.
In this remarkably distinct genus, the body is minute and sparsely
covered with long stiff erect bristles, the beak moderate in length,
evenly, feebly arcuate, with the antennse inserted just beyond the
middle, the prosternum broadly, rather feebly impressed along the
middle, separating the coxse by much less than their own width,
and the tarsi very slender, the third joint elongate, subcylindrical
or feebly obconical and not in the least dilated. Zaglyptus was in-
advertently placed in the Cryptorhynchini by its author.
We have but two species, one of which I do not have before me
at present; they are distinguished by LeConte as follows: —
Elytra with coarsely punctured shallow striae, the intervals rather wide.
1 striatus
Elytra deeply sulcate, the grooves punctured ; interspaces narrow ; color
darker 2 sillcatus
These species appear to be rare, or at least seldom taken ; they
are probably of peculiar habits.

OOMORPHIDIUS n. gen.
It is necessary to separate Microcholus erasus and bjevicoUis of
LeConte as a very distinctly defined genus, forming a passage from
Stethobaris to Eisonyx, and differing radically from Microcholus in
its strongly convex body, tubulate prothorax, peculiarly modified
elytral striation, impressed prosternura and stout, strongly decus-
sate mandibles. In many of its most striking characters it resem-
bles Eisonyx, and in fact is so evidently allied to that genus as to
prove the feeble value of ungual structure in the present section of
Barini ; this is shown also below in the case of Barinus and Bari-
lepton, which are related in much the same way as Oomorphidius
and Eisonyx.
660 ColeojJterological Notices, IV.
Oomorphidius is distinguished by an oval, extremely convex and
subglabrous body, rather long, moderately stout, arcuate beak, with
broadly arcuate and somewhat advanced epistomal lobe, rather
robust legs, with subarcuate femora, dilated third tarsal joint and
very small, slender, free and divergent claws. The scutellum is
minute. The two species differ subgenerically as follows : —
Subgenus I.
Apical constriction of the protliorax not extending across the dorsal surface ;
prosternura narrowly and feebly sulcata, the sulcus squamosa along its
edges ; anterior coxae apparently separated by less than one-third of their
own width; elytra without dispersed squamules ; scutellum nearly as
wide as long ; size larger, the elytra nearly as in Eisonyx and wider tlian
the protliorax 1 erasus
Subgenus II.
Apical constriction in the form of a deep abrupt groove, extending without
change in character entirely across the dorsal surface ; prosternum very
broadly, moderately strongly subsulcate, the sides of the impression not
well defined and completely glabrous; coxae separated by one-half of their
own width ; elytra with a few widely dispersed squamules toward the
sides and apex ; scutellum elongate, triangular ; size small, the protliorax
much shorter and equal in width to the basal parts of the elytra.

long as the first and fully as long as the third and fourth com-
bined ; club robust, moderate in size, abrupt, densely pubescent.

feeble traces. of fine impressed stria?, which are abruptly, deeply
foveate just behind the basal margin, the intervals very minutely

cepting a few long recumbent yellowish squamules at the base of
the second to fourth intervals. Prosternum narrowly and feebly

EISONYX.
LeConte— Trans. Am. Ent. Soc, VIII, p. 216.
This is perhaps the most aberrant and specialized baride genus
within our faunal limits. In general form it is totally unlike our
other genera, but is satisfactorily connected in this respect by Oomor-
])hidius. The original diagnosis of LeConte will serve for its re-
cognition, but is greatly misleading in several important points.
The middle and hind tibiae are, for example, not in the least conical
in outline, but are very thick and quite peculiar in structure, indi-
cating perhaps a burrowing habit ; they are strongly carinate ex-
ternally near the base, then straight for a short distance, then feebly
bent outward, becoming distinctly dilated and densely bristling
with fulvous setae. The el3'tral strife are not by any means replaced
by series of coarse punctures, as stated in the original descrip-
tion, the strife being all but completely obsolete, but marked by
series of exceedingly minute feeble and distant punctures, and ter-
minating at base in larger deep foveas as in Oomorphidius ; the
large deep circular perforate and widely distant punctures referred
to by the author, are unevenly spaced along the middle of the in-
tervals. Each of these large punctures bears a very small slender
seta, but some of them, which are widely isolated and a little larger
than the others, bear instead a single large white recumbent scale.
The beak is extremely thick, short, feebly arcuate and scarcely
three-fourths as long as the prothorax, bristling with coarse erect
setse at the sides toward apex, and the antennae are inserted slightly
beyond the middle, the scrobes being very oblique. Scutellum
minute, rather deeply seated, feebly tumid and nude.

the vestiture extremely unevenly distributed, consisting- of a cluster
of elongate fulvous squamules among the deep coarse punctures
occupying the lateral portions of the anterior thoracic constriction,
also at the base before the scutellum and along the margin toward
the sides, also with a few similar squamules near the base of the
third and fifth elytral intervals; elsewhere on the upper surface,
with the exception of the few widely scattered white scales of the
elytra, the setge are very minute. Head almost impunctate, the beak
sparsely but deeply so, separated from the head by a transversely
arcuate shallow but sharply defined groove. Protborax finely, fee-
bly and very sparsely punctate, as long as wide, convex, the sides
feebly convergent from the base nearly to the apex and straight;
base strongly, anteriorly oblique from the scutellum to each basal
angle, the median lobe nearly obsolete. Elytra about one-half
wider than the prothorax and nearly twice as long; sides about
equally and strongly convergent anteriorly to the base of the pro-
thorax, and posteriorly to the very narrow subtruncate and con-
jointly arcuate apex, the sutural notch completely obsolete. Length

Texas — Cab. LeConte. But two specimens are known, one of
which is in the cabinet of Dr. Horn.
ZYGOBARIS.
LeConte— Proc. Am. Phil. Soc, XV, p. 317.
A single widely isolated subtropical species, with coarsely punc-
tured elytral striae and very long .slender strongly arcuate beak,
alone constitutes this genus as far as known. LeConte placed here,
also, several other small and obscure forms ; these, however, belong
to widely diverse genera, and have been described under the preced-
ing Oligolochus and Idiostethus, and Catapastus which follows.
Zygobaris may be distinguished easily by the structure of the
tarsal claws, which are moderate in length and completely connate,
without trace of suture, through at least one-third of their length.
The mandibles are small, thick, arcuate, notched at apex and strongly
decussate. Prosternum flat, separating the coxa? by about their
own width, the subapical constriction feeble and only visible later-
ally, represented in the middle by a small, moderately deep, sub-
transverse fovea, limited at each side by a small longitudinal ridge.
Other i-eneric characters are mentioned below : —

Robust, rhomboidal, moderately convex, strongly shining, black,
the legs slightly piceous ; integuments subglabrous, the vestiture
white, consisting of very minute and sparse setiform squamules,
with large white scales remotely dispersed but more condensed at
the base of the second elytral interval, more distinct but sparse
beneath. Beak long and slender, evenly, strongly arcuate, slightly
tumid at base with the constriction distinct, feebly compressed and
densely punctured at the sides, especially behind the antennae, two-
fifths as long as the body in the male and two-thirds in the female,
smoother and less punctate in the latter sex ; antennas inserted at
basal two-fifths in the female or a little behind the middle in the
male, the scape nearly attaining the eyes, the scrobes almost com-
pletely inferior, basal joint of the funicle not quite as long as the
next four, the second one-half longer than the third ; club moderate,
elongate-oval, densely pubescent, with the basal joint composing
about one-third of the mass. Prothorax conical, one-half to two-
thirds wider than long, the sides feebly, evenly arcuate ; constric-
tion rather strong ; disk very coarsely, deeply, moderately closely
punctate, without trace of impunctate line. Scutellum small, oblong,
glabrous. Elytra at base much wider than the prothorax, rather
more than twice as long as the latter, parabolic in outline, the
humeral callus not laterally prominent; disk with very fine strige,
which are widely and deeply impressed and coarsely, not closely
punctate, the intervals convex, each with a single series of coarse
deep remote punctures, about as large as those of the striae but more
than twice as distant. Length 2.6-3.7 mm.; width 1.4-2.0 mm.
Southern Florida. A distinct and easily recognizable species.
CATAPASTUS u. gen.
This genus contains some of the smallest centrinides thus far
discovered, and is rather isolated. Its nearest relative is probably
Zygobaris, but the divergence from even this form, which is itself
a strongly specialized type, is very notable.
The beak is short, stout, broad, flattened toward apex, very
densely but finely punctate throughout, squamose and without

large. The mandibles are small, stout, arcuate, notched at apex
and broadly decussate. Scutelluni small, densely squamose. Pro-
sternum with a broad, moderately deep impression along the middle,
which becomes gradually narrower, mpre profound and nipre ab-
ruptly defined toward apex. Anterior coxte rather approximate,
separated by scarcely one-half of their own width. Tarsal claws
small, perfectly connate through about basal third. The two species
before me may be readily recognized as follows : —
Form narrowly rhomboid-oval ; prothorax but slightly wider than long ; scat-
tered white scales of the elytra long and narrow ; legs black ; antennje
piceous, with the club abruptly pale rufo-trstaceous IconspersilS
Form rather broader, the prothorax much more transverse ; scattered white
scales larger, broader and much more conspicuous ; legs and antennae
pale rufo-testaceous throughout 2 difftisiis

Narrow, subrhomboidal, convex, black, the antennae piceous-black
with the club rufous ; vestiture dense, consisting of small narrow
dark red-brown squamules, which are broader, denser and nearly
white beneath, and with larger white scales remotely dispersed on
the elytra and more or less dense toward the sides of the pronotum,
the scutellum densely clothed with white scales. Beak thick, feebly
flattened toward apex, evenly, rather strongly arcuate, as long as
the prothorax in the male and scarcely longer in the female, densely
punctate and squamose, the basal constriction obsolete ; antennae
inserted distinctly beyond the middle in both sexes, basal joint of the
funicle about as long as the next four, second but slightly longer
than the third ; club rather large, oval, densely pubescent, with the
basal joint constituting one-third of the mass and not longer than
the second. Prothorax fully one-third wider than long, conical, the
sides arcuate at apical third, the constriction distinct ; apex three-
fifths as wide as the base ; punctures somewhat coarse, very deep
and dense, without impunctate line ; basal lobe very small. Elytra
distinctly wider than the prothorax and a little more than twice as
long, narrowly parabolic in outline, the striae rather coarse, abrupt,
normal ; intervals flat, about one-half wider than the grooves, finely
but strongly, confusedly and rather rugosely punctate. Length
1.7-2.3 mm. ; width 0.8-1.1 mm.

2 Catapastlis diffusiIS n. sp. — Rhomboid-oval, rather stout, convex,
black, the legs and antennse throughout pale rufo-testaceous : vestiture as in

the median lobe small but rather prominent ; disk coarsely, very densely
punctate, with traces of a fine impunctate line. Scutellum small, rounded,
very densely clothed with white scales. Elytra distinctly wider than, and
obviously more than twice as long as, the prothorax, parabolic, the liumeral
callus rather prominent laterally ; disk not coarsely, deeply, abruptly striate,
the intervals flat, twice as wide as the grooves, finely, closely, confusedly
and subtransversely punctato-rugose. Abdomen nearly flat, closely punctured

Florida (southern).
This species is closely allied to coy^spersits, and resembles it in
structure and vestiture, but differs in its slightly more robust form,
pale legs and antennae, more transverse and more coarsely punctured
prothorax, and in several other characters. It is described appa-
rently from the female, but there is very little sexual disparity in
this genus.
BARIiXUS.
Casey— Bull. Cal. Acad. Sci., II, 1886, p. 255.
In this genus the beak is as short, thick and arcuate as in Baris,
although beyond this mere suggestion, there is nothing at all in
common. As in Barilepton, to which Barinus is closely allied,
the head is larger in proportion to the size of the prothorax than in
any of the other genera, and the tarsi have the second and third
joints dilated, very broadly so in bimttatus, but Barinus can always
be readily distinguished by the tarsal claws, which are two in
number and completely connate through at least one-half of their
length.
The antennae are inserted just beyond the middle of the beak,
very near the median line of the flank, the scrobes rapidly oblique,
the scape nearly attaining the eye, the club moderate and the basal
joint of the funicle unusually long, although varying somewhat in
length in the different species. The mandibles are small, stout,
feebly arcuate externally, decussate and with a large internal notch.
Coleopterological Notices, IV. OGt
Prosternum more or less deeply and narrowly impressed or sulcate,
the coxiB laroi'e, prominent and narrowly separated. The niet-
episternum varies in width according to the species, and the abdo-
men is conv^ex, becoming strongly ascending toward apex, where it
is generally retracted slightly above the plane of the sutural angles
of the elytra. The scutellum is small, glabrous or nearly so and
the body is always unevenly and more or less densely squamose.
The species are moderately numerous ; those known to me may
be identified as follows: —
Body glabrous above, with two wide, abruptly limited vittre of large pale
densely placed scales, the outline evenly elongate-oval. ...1 'biTitta.tllS
Body elongate-oval, unevenly squamose above, the scales forming shorter or
longer lines on the elytral intervals or, when the latter are densely
squamose throughout, with the intervals two, four and six in greater or
less part paler, especially toward base.
Elytra not densely squamose throughout.
Elytral punctures line, the sixth interval with a broad dense line of scales,
abruptly terminating at basal fourth ; white scales of the second inter-
val not extending beyond apical fifth 2 cribricollis
Elytral punctures coarse and dense, the sixth interval with the line of
large white scal,es extending fully to the middle and thence nearly to
apex, but with narrower, sparser and darker scales; second interval
broadly clothed with large white scales from base to apex.

metallic lustre, the legs dark rufo-piceous ; vestiture of the dorsal
surface very minute except a broad vitta on each side, extending
from the apical margin of the pronotum to the elytral apex, of large,
broad, densely placed, yellowish-white scales, the meso- and meta-
sternal episterna and margins of the abdomen similarly clothed with
denser scales. Head excavated l)eneath ; front with a large feebly
impressed fovea but without transverse constriction, the beak stout,
cylindrical, scarcely compressed, evenly, moderately arcuate, three-
fourths as long as the prothorax, polished, coarsely punctured toward
base, the antennse inserted just beyond the middle, a little nearer
the upper than the lower margin, the basal joint of the funicle very
slender and as long as the entire remainder, the club small, elongate-
oval, as long as the four preceding joints combined. Prothorax not

and confusedly punctate, the fourth very narrow toward base. Pro-
sternum narrowly, moderately deeply sulcate along the middle,
separating the coxte by only one-third of their own width. Tarsi
very broad, the posterior as long as the tibise, with the first joint
small but wider than long, the second and third equal in width and
both very strongly dilated, squamose above, densely pilose beneath,

(Barilepton).
Elongate-oval, convex, polished, black, the legs slightly piceous ;
vestiture very uneven, consisting of large white densely placed
scales in a sublateral pronotal vitta, on the second elytral interval
except near the apex, where they are gradually replaced by small
narrow dark brownish squamules, on the third for a short distance
behind the middle, on the fourth near the base and from basal to
apical fourth, and on the sixth in the broadest and most conspicu-
ous line of all, abruptly confined to basal fourth of the length ; on
the under surface the white scales are dense and conspicuous in a
small spot near the anterior coxeb, on the inner half of the mes-
episterna, throughout the met-episterna, and toward the sides of
the abdomen, much more densely on the third and fourth seg-
ments and becoming fine, browner and sparser toward the apical
angles of the second segment, which is more reflexed posteriorly at
the sides than the third or fourth. Beak extremely short, thick,
arcuate, not more than two-thirds as long as the prothorax, strongly
punctured toward base at the sides, the basal joint of the antennal
funicle as long as the entire remainder and slightly longer than the
club. Prothorax verj^ nearly as long as wide ; sides parallel and
straight in basal two-thirds, then gradual!}^ rounded, feebly conver-

fourths as wide as the base; disk coarsely punctate, the punctures
circular, deep, perforate and quite distinctly separated ; impunctate
line evident in basal two-thirds. Elytra distinctly wider than the
prothorax and fully twice as long, narrowly, obtusely rounded at
apex; stride moderately coarse; intervals flat and unequal, about
twice as wide as the grooves, finely, not densely and more or less
confusedly punctate. Presternum deeply, longitudinally impressed,

Elongate-oval, convex, black, the legs red ; elytra coarsely, very
densely sculptured; upper surface in great part covered with large
white closely placed scales, which are replaced toward the sides of
the elytra by smaller browner squamules, becoming fine inconspic-
uous setae toward the humeri, also very inconspicuous on the first
interval except tow^ard the scutellum, and in middle half of the
pronotum, except along the median line; pronotum in entire lateral
fourth and second elytral interval throughout clothed very densely
with large scales. Length 3.1-3.7 mm. ; width 1.2-1.3 mm.
Illinois ; several specimens. This species is allied to vrihricollis,
but differs in its slightly longer, less robust and arcuate beak in the
smaller punctures and much broader, denser lateral vitta of the pro-
notum, in the very much coarser, deeper and denser punctures, and
more conspicuous vestiture of the elytra, paler legs and in many
other characters.
In my original description, the sculpture of the elytral intervals
is stated to be finely and feebly punctate ; this mistake arose from
the fact that in the single type specimen, the dense scales in great
part covered and concealed the punctures ; in some denuded ex-
amples before me, however, they are readily seen to be coarse and
deep, and, in comparison with those of cribricollis, very large in-
deed. The types of both cribricollis and squamolineatus are
males.
4 Bariiilis Sllfflisiis n. .sp. — Elongate-oval, convex, black, with tlie
legs red, moderately sliiuing but extremely densely covered tliroughout with
large brownish scales, becoming broadly white toward base of the sixth inter-
val, also feebly whiter on the second and fourth near the base and behind the
middle, also broadly white in lateral fourth of the pronotum and toward the
sides of the body beneath ; median half of the pronotum sparsely clothed with
slender but distinct squamules, becoming broad dense scales on the median
line toward base, the scutellum abruptly black and glabrous, small, triangu-
lar, widest behind and lying in a broad shallow depression between the elytra.
Head and beak glabrous but with an abruptly dense line of large scales border-
ing the eye anteriorly, the former finely but strongly, not very sparsely punc-
tate, the transverse constriction feeble but evident; beak thick, compressed,
strongly arcuate and distinctly punctate toward base, straighter and feebly
flattened toward apex, about four-fifths as long as the prothorax in the female ;

quite as long as the next six, club as long as the preceding five joints, ratiier
elongate, oval, densely pubescent, with the basal joint constituting less than
one-half of the mass. Prothorax perceptibly shorter than wide, the sides
straight and parallel in basal two-thirds, then broadly rounded, feebly conver-
gent and broadly constricted to the apex, which is three-fourths as wide as the
base, the latter transverse, the median lobe very small, feeble ; disk rather
finely and somewhat closely punctate, the punctures very distinctly separated ;
impunctate line feebly defined ; apical margin polished and impunctate for a
short distance throughout the width. Elytra distinctly wider than the pro-

line, the apex with a feeble sutural notch, the humeral callus long but not
prominent ; disk moderately striate, the intervals flat, confusedly, coarsely
punctate when denuded. Prosternum deeply impressed along the middle,
rather narrowly separating the coxae as usual. Fifth ventral segment with a
small impressed and denuded median area, the last three segments rapidly
ascending in the female type, convex, and, at the extreme apex, retracted
above the plane of the elytral apices. Length 3.6 mm. ; width 1.4 mm.
Texas.
A single specimen, which appears to be a female, the abdomen
being entirely devoid of median impression toward base. The
species is allied to squamolineotus , but is easily distinguishable by
the dense crust of scales, and the much finer denser punctures and
conspicuous squamules of the i)ronotum.
5 Barinus difHcilis n. sp. — Elongate-oval, convex, black, shining,
the legs rufous ; vestiture dense, consisting of large close-set scales, pale brown
ip color but gradually white in basal half on the second and sixth intervals,
and also on the fourth very near the base, also broadly white and dense at the
sides of the pronotum and on the under surface toward the sides, but with a
large subdenuded spot on the prothorax just before the mesosternal side-
pieces, which is sparsely clothed with long slender squamules ; median parts
of the pronotum rather sparsely clothed with very long, wider and narrower,
brown scales, which are conspicuous. Head finely, sparsely punctate, gla-
brous, the eyes margined anteriorly with an abrupt line of coarse scales ; im-
pression feeble but distinct ; beak glabrous, thick, strongly arcuate and
densely punctate toward base, much shorter than the prothorax, the basal
joint of the antennal funicle distinctly shorter than the remainder; club
moderate. Pi-othorax not quite as long as wide, the sides parallel and nearly
straight to apical third, then broadly rounded and moderately convergent to
the apex, the constriction almost completely obsolete ; disk coarsely, deeply

California (southern).
This species is rather closely allied to siiffusus, but differs iu its
much more sparsely punctate head, in its coarser, denser punctures,
narrower lateral vittae, more uneven and more conspicuous vestiture
of the median parts of the pronotum, and in the denuded area
beneath, the latter being entirely wantina: and clothed with large
dense normal scales in i>uffusus. It also differs in having the met-
episterna decidedly narrower, and the elytra covered with a dense
crust of scales which entirely conceal even the stri«, the latter being
indicated by wide partings of the scales in suffusus.

tributed on the elytra, where they become gradually semi-erect
behind and denuded at the sides in more than basal half, also broadly
dense at the sides of the pronotum, the median glabrous area oval
in outline; under surface polished and with very minute remote
setiform squamules, which are abruptly dense and broader on the
met-episterna and at the sides of the abdomen behind. Beak thick,
strongly arcuate and punctured at base, three-fourths as long as the
prothorax, the transverse impression very broad ; surface glabrous
but with a few very small, scarcely visible squamules near the an-
terior margin of the eye ; basal joint of the antennal funiole as long
as the next five ; club rather small, but slightly longer than the pre-
ceding four joints combined. Prothorax fully one-third wider than
long, the sides parallel and nearly straight in basal two-thirds, then
broadly rounded, convergent and scarcely at all constricted to the
apex, the latter scarcely more than one-half as wide as the base ;
disk rather coarsely and sparsely punctate, the punctures becoming
smaller and much denser anteriorly. Scutellum very small, tumid,
quadrate, glabrous and polished. Elytra scarcely perceptibly wider

minent, separated by scarcely more than one-fourth of their own
width. Length 8.2 mrn. ; width 13 mm.
Texas (Columbus). Cab. LeConte. The unique type is the only
specimen which I have seen ; it is a female. This species is allied
to albescens, in spite of the great dissimilarity in form of the body;
the arrangement of the vestiture beneath is almost identical, but
lutescevs does not possess the denuded subapical spot of the elytra,
is much more coarsely punctate, and differs in so many characters
that there cannot, I think, be the least doubt of its distinctness.
7 Barinus curticollis n. sp. — Rather narrowly oblong-oval, some-
what convex, polished, black, the legs dark rufo-piceous ; vestiture yellowish,
consisting, on the pronotum, of dense elongate-oval scales in lateral third, on
the elytra of nearly similar scales almost uniformly but not very densely dis-
tributed throughout, becoming finer and still sparser on the flanks, very sparse
throughout beneath, except on the met-episterna, where they are much denser,
also denser at the sides of the last three ventral segments. Head dull, finely,
sparsely punctate, the impression distinct ; beak short, thick, very strongly
arcuate, not as long as the prothorax, coarsely but sparsely punctate, some-
what squamulose above the eyes ; antenna slender, the basal joint of the fuui-
cle not quite as long as the remainder, club moderate. Prothorax short, two-
fifths wider than long, the sides parallel and straight to apical third, then
gradually rounded convergent and nearly straight to the apex, which is three-
fifths as wide as the base, the latter transverse, the median lobe broad and
feeble ; disk coarsely, rather sparsely punctate, the punctures round, deep,
perforate and isolated, with a narrow and irregular impunctate line. Scutel-
lum small, oval, tumid and glabrous. EUjtra slightly wider than the prothorax
and nearly two and one-half times as long, elongate hemi-elliptical, obtusely
rounded at apex, the humeri not laterally prominent ; disk deeply striate, the
intervals flat, from two to three times as wide as the grooves, coarsely, con-
fusedly but not very densely punctate. Abdomen finely, remotely punctate,
the basal segment coarsely and much more closely so. Anterior coxfe sepa-
rated by about one-half of their own width. Length 2.7-3.0 mm. ; width
1.0-1.2 mm.

The description is drawn from the male, the abdomen having a

allied to lutescens, but differs in its shorter prothorax, narrower
form, more slender, much sparser scales of the elytra and more
widely separated anterior coxtB.

toward apex, and the entire vestiture in apical fourth erect and
bristling, especially at the intersection of the third and ninth in-
tervals, behind the feeble subapical callus ; vestiture of the under
surface very minute and sparse, but denser on the met-episterna
and at the sides of the abdomen behind. Beak three-fourths as long

three or four subrecumbent scales; antennae with the basal joint of
the fuuicle as long as the next five, the club rather large, pale, nearly
as long as the preceding six joints. Prothorax a little wider at

BARILEPTON.
LeConte — Proc. Am. Phil. Soc, XV, p. 318.
The species of Barilepton are probably the most slender of the
Barini. The beak is short, thick, arcuate, strongly compressed,
with the flanks crossed obliquely by the antennal scrobes, the latter
beginning near the upper margin and slightly beyond the middle.
The under surface of the head is frequently excavated transversely
as in Barinus, and the basal joint of the funicle is elongate. The
prosternum is broadly impressed and very narrowly separates the
coxfe. One of the most remarkable characters of the genus is the
structure of the tarsi, in which however it strongly resembles Bari-
nus ; the four posterior tarsi are almost invariably longer than the
tibiffi, and have the second and third joints dilated, the first being
GTG Coleopterological Notices, IV.
much smaller. There is but one tarsal claw, which is simple and
moderately stout.
The close relationship existing between Barilepton and Barinus
affords another illustration, parallel to that of Eisonyx and Oomor-
phidius previously mentioned, of the slight value to be attached,
among some of the centrinide genera, to radical differences in the
tarsal ungues, in comparison to the significance attending these
modifications in the baride series.
Our four species of Barilepton may be thus defined: —
Elytra at base not wider than the base of the prothorax.
Beak almost evenly arcuate 1 fllifoi'iue
Beak strongly bent near the base ; body much smaller and still more slen-
der; pronotal vestiture decidedly sparser 2 famelicilin
Elytra at base wider than the contiguous base of the prothorax ; form a little
stouter, the prothorax much less elongate.
Prothorax constricted behind the apex; antennal club robust; basal joint
of the hind tarsi longer, the second not quite as wide as the third and
rather longer than wide, the third a little wider than long.
3 qiiadricolle
Prothorax without trace of subapical constriction ; antennal club much

This very small species is closely allied io filiforme, but may be
distinguished by its smaller size, more slender form, sparser and
more slender scales especially on the pronotum and along the median
parts of each elytron, and also by the form of the beak which is more
abruptly and strongly arcuate near the base. Seven specimens.

EuchatesW LeConte — I'roc. Am. Phil. Soc, XV, p. 319.
This genus was proposed by LeConte, unfortunately under a
name which had been employed several times before in zoology, for
one of the most remarkable curculionides thus far discovered. Its
aberrant nature was in fact only partially known to its author,
who makes no reference whatever to the mandibles. The general
habitus of the body, abdominal structure and conformation of the
mes-epimera, show that it is a normal member of the Barini, but
its rostral and mandibular characters indicate that it should be
widel}'- isolated, forming with Plocamus a group or subtribe.
The beak is extremely slender, cylindrical and strongly arcuate,
but becomes abruptly inflated and thickened behind the antennae,
the under surface of the dilated portion having a narrow deep
groove along the middle, which is gradually narrowed posteriorly
and confluent at base with a deep transverse constriction, extend-
ing upward at the sides just in front of the eyes, becoming gradu-
ally attenuated and extinct and not attaining the upper surface.
This longitudinal groove is but a remnant of the usual channel
formed by the confluent scrobes, and is far too narrow to receive
the antennal scape, the latter being free. The antennte are com-
pletely inferior in insertion and are situated between basal third
and fourth in both sexes, the scape rather thick, short and extend-
ing to the under surface of the head between the eyes, the latter
being normal and widely separated beneath.
The mandibles are very short and thick, compressed, bent upward
and move in a nearly vertical plane as in Balaninus, the condj'les
being contiguous above and received in broad deep fissures at the
080 Coleopterological Notices, IV.
sides of the buccal opening beneath ; the upturned apex is very
coarsely and deeply notched. It can be readily seen that in this
position, the condyles have the largest and most powerful muscular
attachment permissible under the circumstances. The habits of this
species, as well as Balaninus, necessitate a slender cylindrical boring
tool, not at all enlarged at apex, and, if the condyles were horizontal
in their plane of motion, they would, because of their slight lateral
development, be very feeble in muscular action ; they have there-
fore been gradually turned into a position as nearly vertical as pos-
sible, simply to allow of a broader base for the attachment of the
muscles. Mandibles of this kind are of course incapable of grasp-
ing or pinching to any useful degree, and can be used only in cut-
ting and scraping a passage for the advancing beak, and it does not
follow at all that because the mandibles are similar in their action
to those of Balaninus, that there is any special relationship between
these genera. In point of fact the remaining structural characters
of the body, including the form of the mandibles themselves, are
so widely different in Balaninus and Eunyssobia, that there cannot
be the least affinity between them, except in the method of using
the beak as a boring instrument.
The buccal fissure is very narrow and deep, being, at the anterior
extremity, not more than one-fourth as wide as the rostrum, and
the mentum is long and extremely slender; the remaining organs
of the mouth appear to be atrophied or very feebly developed. The
prosternum is broad, strongly, transversely constricted behind the
apex but not otherwise modified, and separates the rather small
coxie by nearly twice their own width. The legs are normal, the
tarsi very slender, with the two basal joints elongate, feebly ob-
conical and subequal, the third small, scarcely wider than the apex
of the second, deeply emarginate, the fourth with its basal node,
about as long as the first two together ; claws rather slender, arcu-
ate, simple and divergent. Pygidium completely concealed.

as long as the body in the female, sensibly shorter but otherwise
entirely similar in the male, very slender, cylindrical, glabrous,
shining, sparsely punctured in even series, evenly and stronglv
arcuate from the antennae to the apex, but abruptly, strongly in-
flated, thickened but straight in lateral profile, spinose and very
densely covered with a rough crust of scales from that point to the
base ; antennae slender, the scape short, the basal joint of the funicle
subequal to the next two ; club moderate, oval, densely pubescent
and without distinct sutures. Prothorax much wider than long,
very strongly constricted and tubulate at apex, the base twice as
wide as the apex, transverse but deeply sinuate at each side of the
lobe, which is abrupt, prominent and rounded, its surface with a
dorsal impression receiving the scutellum ; disk uneven, a large
shallow impression on each side of the median line, behind the
middle, especially obvious. Scutellum moderate, slightly tumid,
oval, ogival behind, anteriorly prominent in the middle of the sinua-
tion which receives the thoracic lobe and slipping partially over the
surface of the latter. Elytra barely as long as wide, distinctly
wider and two-thirds longer than the prothorax, the sides rapidly
convergent and broadly evenly arcuate from base to apex, the latter
very narrowly rounded, ogival, with a small sutural notch ; striae
indicated only by very fine partings of the crust. Under surface
and legs densely clothed with a squamose crust of cinereous scales
and with short sparse erect and stiff setae. Length 2.6-3.2 mm.;
width 1.3-1.6 mm.
Ohio, Kentucky and Iowa, apparently not rare and said to depre-
date upon the hickory; its habits are probably quite similar to those
of Balaninus. It should be remarked that in some species of Cen-
trinus, such as hospes, the beak is strongly inflated behind the an-
tennae, especially in the female and probably from causes similar to
those which have produced the inflation here ; but in Eunyssobia it
does not appear to be at all sexual in character, and, in the species
of Centrinus, the antennae are not inferior in insertion, although in
hospes they are inserted very near the lower margin, the scrobes
being broad and entirely inferior.

The single small species forming the type of this genus is unmis-
takably allied to Eunyssobia echidna, but differs in several peculi-
G82 Coleopterological Notices, IV.
avities of indubitable generic import. The principal of these are
the shorter beak, which is gradually stout and conical near the base
and not abruptly inflated, the channel beneath being broad, shallow,
and serving as a partial shelter for the antennal scape, the absence
of any trace of the transverse basal constriction, and the shorter
second joint of the antennal funicle. The mandibles are entirely
similar, but the trophi, and especially the maxillary palpi, seem to
be larger and better developed, and the tarsi are shorter, particu-
larly the second joint, which is but slightly longer and scarcely at
all narrower than the third, the fourth being nearly as long as the
first three together.

ally noticeable; under surface white; erect dorsal bristles very short
and sparse. Beak but slightly longer than the head and prothorax,
slender, arcuate, glabrous, linearly [)unctated and finely bicarinate

robust thence to the base, the basal portion densely clothed with
large rough concave and squamiform plates; antennae inserted at
basal fourth on the under surface, the scape short, attaining the
head, the basal joint of the funicle slightly longer than the next two,
second one-half longer than the third, seventh obconical, nearly as
long as the fifth and sixth, club small, slender, not abrupt, oval,

I.
It is to be regretted that a number of species, described by the
older writers, continue to remain unknown, and that it will be for-
ever impossible to surely identify them, because of the neglect on
the part of their several authors to record structural characters,
which might enable us to form an opinion concerning their proper
generic positions. These species are the following: —
1 Baridius anthracinus Boh. — Sch. Cure, III, p. 727.
The depressed form may indicate a close relationship with Limnobaris, as
before remarked (p. 554), but I do not know any species with decidedly trans-
vei-se interstitial punctuation ; perhaps, like crevatus, the references to which
are similar in the Munich Catalogue, it may be Mexican and not an inhabitant
of the United States.
2 Baridius californicus Mots. — Bull. Mosc, 1845, II. p. 372.
May possibly be the species subsequently described by LeConte under the
name Centrimoi nastdiis. At any rate it might for the present be appropriately
assigned to Limnobaris.
3 Baridius californicus Boh. — Eug. Res., Ins., 1859, p. 137.
This is probably a species of Baris, allied to ritbripes, but having the beak
longer and the elytral intervals smooth, or it may possibly be Onychoharis
Aeriala. It is said to have been taken near San Francisco,
4 Baridius confertus Boh — Sch. Cure, III, p. 728.
Described from Florida. It may be assigned at present to Onychobaris,
although I have never seen a representative of that genus from the Atlantic
regions.
5 Centrinus dilectus Harris — Trans. Hart, Soc. Nat. Hist., 1836, p. 79.
The description enables us to assign this species to Centrinus without much
doubt, and it may possibly be a large female example of one of the densely
squamose variations of Centrinus saUbrosus. The locality is not recorded.
6 Centrinus pistor Germ. — Sch. Cure, III, p. 170,
I can add notliing to the remarks made by LeConte (Proc. Am. Phil. Soc,
XV, p. 433), except to suggest that this also may be the female of CenfrjHMs
salehrosus, or of a species closely allied.

Baris scolopacea Germ. — This species, introduced from Europe, may be
known by its elongate-oval, convex form and dense but uneven vestiture
of white and brown scales, of which a subsutural white spot at the middle of
eacli elytron is especially conspicuous. I have seen several specimens taken
near Philadelphia.
Scolopacea may be attached provisionally to Baris, but the long
beak, separated from the head by a fine deep abrupt groove, and the
Annals N. Y. Acad, Sci,, VI, Nov. 1892.— 45

scaly vestiture, would necessitate its removal from the genus if
studied with reference to the homologies of the American series of
genera. The European species of Barini are more difficult to treat
generically than our own. Some of them, such as schwarzenbergi,
limbata, artemisiae, atronitens, carhonaria, chlorizans, and other
similar forms, seem to be consistent with our conception of Baris,
but there are many aberrant types, having the beak longer or sepa-
rated from the head by a deep abrupt groove, or with the third
tarsal joint undilated, the body covered with a waterproof coating
of scales, or the tarsal claws subconnate at base, such as spoliafa,
loricata, convexicollis, jncturata, sellata and nitens, which cannot
be retained in Baris proper, and yet the structural differences do not
appear to be great. In judging genera in this tribe, especially
among the European representatives, much dependence will have
to be placed upon that summation of minor characters known as
" habitus", and, if with this difference of facies we can perceive
some real structural peculiarity, a study of the European species in
connection with our own seems to show that it will eventuall}^ have
to be accepted as a generic criterion. There is no other way in
which the old and new world species can be consistently arranged
in homogeneous succession from a generic standpoint.

CACTOPHAGUS Lee,
This is a very w^ell defined and somewhat isolated genus, dis-
tinguishable from Sphenophorus by the larger smoother body, cyl-
indrical uncompressed beak and several other characters. It will
include a number of species inhabiting northern Mexico and the
regions adjacent. Our species are entirely black, but there are
several before me from Mexico, in which each elytron has a sub-
basal and subapical crimson fascia. The two species which are at
once distinguishable among the Arizonian specimens in my cabinet,
may be described as follows :—
Coleopterological Notices, IV. 685
Body densely dull and velvety-black above, not in the least shining, the pro-
notiiin not transversely grooved at base; elytral strise but just visibly
coarser near the base, very finely, remotely punctate through(jut, the
punctures only slightly less minute laterally. Length 22.0 mm. ; width
8.7 mm Talidlis Lee.
Body less dull, alutaceous, not at all velvety, the head and beak polished ;
punctures throughout larger and deeper ; pronotum with a deep entire
transverse groove before the basal margin ; elytral striae fine but very
deep, much coarser and more strongly punctate toward base, distinctly
and less remotely punctate throughout, the punctures distinct by un-
aided vision laterally and toward base ; elytra relatively less elongate.
Length LS-O-IG..*) mm. ; widtli 7.0-8.0 mm. Arizona. Three specimens.
subnitens n. sp.
Siibnifens is not to be confonnded with the individual variation
doscriljed by Dr. LeConte under the name procerus, the latter is
dull, opaque and velvety-black like the typical forms of validus.
The dull lustre in this genus is caused, not by granuliform re-
ticulations, but by a beautifully regular system of extremely minute,
subcontiguous but not in the least confluent punctures, which are
deep and with the edges abrupt. In validus these minute punc-
tures are finer and deeper than in siibnitens ; in the latter each of
the fine sparse punctures of the intervals is surrounded by a pol-
ished ring, caused by an obliteration of the minute ground-sculp-
ture, while in validus these areolae do not exist.
CALAXDRA Clairv.
It is possible that this genus may have originated in the hypo-
thetical continent, represented at present by a few islands extending
from Ceylon to Madagascar ; several species are, however, now
endemic in the East Indies and one or two perhaps on the west
coast of South America. From these regions a number of species
have been distributed throughout the world in various kinds of
grain. It is quite impossible, therefore, to be sure of the native
country of any unfamiliar forms which may occur among us, and,
perhaps because of this uncertainty, the genus as a whole has been
neglected of late by systematic writers.
In arranging the numerous examples in my cabinet I find four
widely distinct species and two subspecies. The true species, one
of which it is impossible to identify from published descrii)tions,
may be characterized as follows : —
G8fi Coleopterological Notices, IV.
Elytra with impressed and feebly punctate sulci, the intervals smooth and
alternately wider and more elevated especially toward base ; pronotura
with coarse sparse and elongate punctures graiiai'ia
Elytra with contiguous double series of coarse deep punctures, the double
series separated by narrow uniseriately punctate intervals.
Pronotal punctures fine even and distinctly separated, the surface smooth
and unusually convex linearis
Pronotal punctures rather coarse, deep, very dense especially toward the
sides, rounded and not elongate, the surface rather depressed on the disk.
oryzae
Pronotal sculpture extremely coarse deep and dense, consisting of long
sinuous anastomosing and obscurely punctate rugse, with a narrow but
entire subcariniform median line ; elytral sculpture exceedingly deep and
dense Mlgicollis

Cure, IV, p. 979.
The differences given by Gyllenbal to distinguish 7'emofepKnctafa
are apparently not sufficient, for, color being of little or no value,
the only character given to distinguish it is the slightly greater
distinctness of the strial punctures toward the suture and of the
punctured series of the sutural interval. Length 3.3-4.0 nnn. ;
width 1.1-1.3 mm.
Distributed throughout the United States.
C. linearis Hbst.— Kaf., VII, p. .5, t. 100, f. 1.
Described from the West Indies but occurring at times in the
Atlantic States. It may always be known by the fine even punc-
tuation of the pronotum. Length 3..3-3.8 mm. ; width 1.1-1.15 mm.
Probably a native of India, from which region a variety is noted
in the Munich Catalogue.
C. oryzae Linn. — Amoen. Ac, VI, 1763, p. 395.
The typical form of this cosmopolitan species is perhaps the
smallest member of the genus. It somewhat resembles the two
previous species in outline, but is very densely punctured on the
pronotum, the punctures much coarser than in linearis and not
elongated as in granaria. A series of eleven specimens of what
may be regarded as the typical form, give the length 2.1-2.8 mm.
and width 0.75-1.0 mm.
Var. zea-mais Mots.— Etud. Ent., IV, 1855, p. 77.
Similar in every appreciable detail of structure to oryzae, but
always larger and especially stouter. A series of eight specimens
Coleopterological Notices, IV. C87
from Texas (Austin) and Florida give the following dimensions.
Length 3.2-3.4 mm. ; width 1.1-1.25 mm.
Another variety is represented before me by two specimens from
Guerrero, Mexico, which are of about the same size as zea-mais,
but more coarsely and densely punctate, and more opaque, with the
elytral punctures more quadrate.
C. rugicollis n. sp. — Oval, moderately stout, rather flattened above,
dull, very sparsely clothed with short erect yellowish setse, forming single
series on the alternate elytral intervals. Head deeply but not coarsely,
rather sparsely punctate, with a large deep fovea between the eyes ; beak
in the female slender, feebly arcuate, smooth, minutely sparsely and sub-
seriately punctate, fully as long as the prothorax, abruptly and angularly
dilated, duller and coarsely, seriately punctate near the base ; antennse in-
serted at basal sixth, slender, the second funicular joint obconical and one-
half longer than the third. Prothorax barely as long as wide, the sides rather
strongly convergent from near the base, rounded at base, deeply, tubularly
constricted at apex, the latter fully one-half as wide as the base ; disk deeply,
rugosely punctate. Scutellum dull, impressed. Elijtra at the humeri exactly
equal in width to the disk of the prothorax, two-fifths longer, the sides strongly
convergent throughout and nearly straight ; apex conjointly rather narrowly
rounded ; disk with contiguous series of very coarse, quadrate, closely crowded
punctures, alternately separated by narrow flat intervals, each of which is
coarsely, uniseriately punctate, the punctures oval and almost contiguous.
Pygidiuin and under surface coarsely deeply and densely punctate. Length
4.0 mm. ; width 1.5 mm.
Florida.
A single specimen, taken b}- Mr. F. Kinzel in the southern part
of the State and presented to me by Mr. W. Jiiiich. This species
is undoubtedly allied to the African rugonirf; Thunb,, but differs
according to the description of ScLo.iherr, in its much shorter, non-
canaliculate prothorax, and its more strongly and closely punctate
abdomen. Riigicollis is brownish-black in color, the elytra each
clouded feebly with rufous along the middle. The base of the pro-
thorax is transverse and perfectly straight. In riu/ot^ns the pro-
thorax is said to be one-half longer than its basal width.

eyes, much more abbreviated, dilated and semi-corneous antennal
club, deflexed beak, short legs, and smaller size of the body. The
three species before me may be easily separated as follows : —
Piceoiis-brown, the punctuation of the upper surface finer and more remote.
Body narrowly cylindrical, the elytra more tlian twice as long as wide ;
punctures of the elytral series becoming very fine and feeble in apical
half, the fifth and sixth series coalescent at base; humeri tumid and
prominent frontalis
Body much more robust, the elytra not quite twice as long as wide ; punc-
tures of the elytral series deep throughout, although small in apical half
as usual ; fifth and sixth series widely separated at base ; humeri not
tumid sliarpi
Black, much larger, coarsely and deeply sculptured ; legs and tarsi stouter.

Readily distinguishable by its slender cylindrical form and eas-
taneous color. The prothorax is very nearly as long as wide, the
sides broadly, evenly arcuate, the apex finely and deeply constricted,
three-fourths as wide as the base, the latter broadly evenly and just
visibly arcuate. Elytra but slightly wider than the prothorax and
much more than twice as long, strongly alutaeeous especially be-
hind, the series feebly impressed, the intervals toward base three
to four times as wide as the strial punctures, sparsely punctured.

Allied to frontalis but disting'uishable by its stouter form, more
polished integuments, much less prominent humeri and several other
characters. I take great pleasure in dedicating this species to Dr.

Y. groSSUS n. sp. — Oblong, subcylindrical, broadly feebly convex above,
deep black, polished, the elytra dull. Head coarsely, rather sparsely punc-
tate ; beak in the male straight, wider than thick, coarsely, densely, rugosely

JWET0P0T09IA n. gen.
The single species is an interesting addition to the anomalous
group of genera allied to Gononotus,
Body in form and convexity nearly as in Gononotus. Head short, sub-
globular, smooth and polished, deeply, transversely incised throughout just
behind the eyes, which are situated at the sides of the beak at base, rather
large, distinctly convex and composed of very large facets, which are flat
and not convex. Beak rather long, thick, parallel and arcuate, the anten-
nal scrobes rapidly descending at first, becoming completely inferior, not
coalescent. j^ntennse subcylindrical, long but thick, inserted at apical two-
fifths, the scape clavate, attaining the limits of the eye beneath, longer than
the apparent funicle, the latter consisting of six joints, the first scarcely more
robust, oval, the second obconical, subelongate, much longer than the first and
one-half longer than the third, three to six subequal, wider than long, paral-

lel-sided, not increasing much in thickness, with the articulations deep ; club
large, as long as the preceding five joints, complex in structure, the basal half,
composed of the modified seventh funicular joint, obconical, as long as wide,
polished and sparsely setose, the apical paler, oval, obtuse, densely pubescent
and indistinctly annulate. Scutellum small but distinct. Metasternnm short.
Anterior coxje large, globular, extremely approximate ; intermediate very
narrowly separated ; posterior rather remote. Legs somewhat long and thick ;
femora sinuate beneath near the apex ; tibife snbparallel, the apical uncus
well developed, the anterior also with an internal subapical tooth; tarsi
cylindrical, rather stout, the third joint scarcely visibly thicker and sparsely
setose beneath, not bilobed.
From Gononotus this g-enus differs in its composite antennal club,
undilated third tarsal joint, elongate prothorax, smooth, polished
head and many other characters.
M. repeus n. sp. — Elongate-ovoidal, convex, dull, black and subgla-
brous, each large fovea, however, with a small fulvous seta; there are also
a few clusters of such setse on the more tumid portions of the elytral intervals.
Head glabrous; beak not quite as long as the prothorax, dull, with coarse
sliallow punctures, sublinearly arranged but becoming finer and irregular to-
ward apex. Prothorax quite distinctly louger than wide, the sides parallel,
broadly feebly and evenly arcuate, rather abruptly rounded and moderately
deeply constricted behind the apex, the latter three-fourths as wide as the
base and broadly sinuate in the middle ; base broadly feebly snd evenly arcu-
ate ; disk evenly, feebly convex, very coarsely, remotely foveate, the fovese
shallow, rounded, and annulate just within their edges with fine cinereous
tomentum ; median line finely and strongly carinate, the carina attaining
neither base nor apex. Elytra oval, at the middle one-half wider than the
prothorax, not quite twice as long as the latter ; humeri obsolete ; base broadly
emarginate ; disk with series of very large deep and unevenly impressed fovere,
the intervals uneven, not wider than the series and remotely, feebly tumorose,
the tumid parts setose and also finely cinereo-tomeutose. Under surface
coarsely, remotely foveate, the fovefe shallow. Length 5.2 mm. ; width 2.(> mm.

fauna excluding the genus Cossonus.
HIMATIUM Woll.
There is some doubt concerning the actual identity of Wollas-
ton's genus with the species assigned to it by LeCoute. Accord-
ing to the description, however, it must be very closely allied to
Coleopterological Notices, IV. 691
our representatives, to such a degree indeed that these could not
be advantageously separated without inspecting the original type.
As represented by nigrituhim, the genus has the body rather de-
pressed above, feebly cuneiform, with the head short and almost en-
tirely enclosed within a snbtubulate extension of the prothorax, the
eyes small, flat, coarsely faceted and in great part inferior, not visible
from above but widely separated beneath. Beak short but slender,
feebly arcuate, parallel, inserted at an angle with the surface of the
front, so that it is distinctly separated from and very much nar-
row'er than the head. Antennae inserted quite distinctly behind the
middle, the scrobes nearly horizontal, not attaining but directed
upon the eye ; scape short, clavate ; funicle slender, 7-jointed, the
basal joint rather longer than the next two; second to seventh
feebly increasing in thickness, equal in length, subquadrate; club
as long as the preceding four joints, narrowly fusiform, polished,
sparsely setose, not annulate. Scutellum distinct. Prosternum
flat ; anterior coxte remote, separated by fully their own width ;
intermediate one-half more widely separated. Metasternum long.
Legs short, slender ; tibiae without internal spur, the uncus well
developed ; tarsi short, the third joint feebly dilated, the fourth
about as long as the preceding three combined.
The three species, which it is necessary to include at present
within the genus, may be recognized as follows: —
Prothorax truncate laterally at apex, remote from the eyes.
Body parallel, ferruginous, densely but coarsely pubescent, the pronotum
coarsely, subconfluently punctate, the elytral series coarse and appi-oxi-
mate errans
Body subcuneate, more convex, black, much less pubescent, the pronotal
punctures much smaller, distinctly defined ; elytral series not impressed,
the intervals wide Ilij^l'itulum
Prothorax partially concealing the eyes at the sides ; beak not distinctly sepa-
rated from the head by a transversa impression COllicuilt
H. conicani must certainly constitute a genus distinct from that
including errans, if the characters given by LeConte are correct
(Trans. Am. Ent. Soc, VIII, p. 218), and the probabilities are
that each of these species will ultimately become the type of a dis-
tinct genus.
H. Iligritllllini n. sp. — Black, the elytra somewhat shining, legs, an-
tenn;e and apical parts of the prothorax piceous-brown, vestiture very sparse,
consisting of erect setiform scales, especially visible on the beak and toward
692 Goleopterological Notices, IV.
the eljtral apex. Head smooth, vaguely sculptured, polished ; beak three-
fourths as long as the prothorax, opaque, finely but deeply, rugosely and
very densely sculptured. Prothorax conical, a little longer than wide, con-
stricted behind the apex, the apical tabulation feebly inflated, receiving the
head ; apex three-fourths as wide as the base ; punctures moderately coarse,
deep, rounded but subcontiguous, without median line. Elijtra slightly wider
behind the middle than at base, nearly two-thirds wider than the prothorax
and more than twice as long; sides feebly arcuate, abruptly convergent and
sinuate near the apex ; humeri broadly exposed but rather obtuse ; disk with
unimpressed series of moderately l§rge deep oblong and almost contiguous
punctures ; intervals flat, a little wider than the serial punctures, feebly
rugose but shining. Under surface densely deeply and rather coarsely punc-
tate. Length 1.75 mm. ; width 0.6 mm.

ALLOJUfiltlUS Lee.
In this genus the beak is rather thin or but moderately stout,
nearly straight, parallel, not conspicuously separated from the
front, the eyes moderate in size, rather convex, not very finely
faceted and situated at the sides of the head, the antennal scrobes
deep, sublinear, directed feebly downward to the lower limit of the
eye, the funicle t-jointed, with the basal joint larger, the second
obconieal and distinctly longer than the third. Our two species
differ greatly in structure and should perhaps be assigned to sepa-
rate subgenera ; they may be defined as follows : —
Beak thinner, a little more than one-half as long as the prothorax ; anterior
coxae larger, separated by their own width ; elytra deeply striate, the
sulci coarsely punctate, the sutural sulcus much less distinctly so.
dllbillS Horn
Beak shorter and stouter, scarcely one-half as long as the prothorax ; pronotal
punctures smaller and closer ; elytra feebly sulcate and much less coarsely
punctate, the punctures of the sutural stria as distinct as the others ; an-
terior coxse much smaller and more remote, separated by nearly twice
their own width. Head polished, almost impunctate, separated from the
beak by a feeble transverse impression, the beak throughout coarsely
deeply and subrugosely punctate. Prothorax about as long as wide,
snbconical, feebly depressed above, slightly constricted behind the apex,
the latter barely two-thirds as wide as the base. Scutellum distinct.
Elytra a little wider than the prothorax and about twice as long, par-
allel, the sides convergent and nearly straight in apical third, the apex
narrowly I'ounded. Abdomen deeply but not very densely and somewhat
unevenly punctate. Length 1.9 mm. ; width 0.65 mm. Texas CColumbus

Coleopferological Notices, IV. 693
Politus is slightly smaller, relatively broader and more depressed
than dubius, and may be known at once by the shorter beak, finer,
more even sculpture, paler color and smaller, much more remote
anterior coxae.
STENA^fCYLUS n. gen.
The principal characters may be expressed as follows: —
Body elongate, slender, convex, the scutellum distinct, the metasternnin
elongate and the anterior coxae widely separated. Head rather elongate, coni-
cal ; beak short, broad, parallel, not in the least constricted or transvei'sely
impressed at base. Antennae inserted behind the middle, the scrobes deep,
beginning beyond the middle, rapidly descending to the lower margin of the
eye ; scape moderate in length ; funicle 7-jointed, the basal joint rather stout,
as long as the next two ; second to seventh rather short, subequal, feebly in-
creasing in width, just visibly obconical ; club moderate, oval, densely but
coarsely pubescent, with the basal joint constituting about one-half of the
mass. Eyes not very large, situated at the sides of the head, very convex,
prominent and coarsely faceted. Legs short ; tibise rather slender, with a
small internal spur at apex, the external uncus well developed ; tarsi rather
stout, the third joint feebly dilated, fourth slender, arcuate, not quite as long
as the three preceding together.
This genus is allied to Macrancylus, but differs in its rather
stouter, more elliptic body and radically in its oblique and not hori-
zontal scrobes, also in its more prominent and coarsely faceted eyes,
and parallel beak; in Macrancylus the beak is conical in form.
From Rhyncolus it may be known at once by its more widely
separated coxse and coarsely faceted eyes, as well as its more slender
bodily form.
S. COlomboi n. sp. — Elongate, narrowly oval, cylindrically convex,
glabrous, polished and pale rufo-piceous throughout. Head and beak con-
tinuous, transversely convex, finely but strongly, not very densely punctate,
the eyes situated at a great distance from the prothorax ; beak scarcely as long
as the head and two-fifths as long as the prothorax, straight. Prothorax a
little longer than wide, broadly, very feebly constricted near the apex, the
sides feebly arcuate ; apex slightly arcuate, three-fourths as wide as the base ;
punctures rather fine but strong, uneven but separated by about their own
widths without trace of median line. Scutellum small, oval. Elytra dis-
tinctly wider than the prothorax and more than twice as long, twice as long
as wide, the sides parallel and straight to apical third, then convergent and
sinuate, the apex narrowly obtuse ; humeri right ; strife coarsely feebly im-
pressed, coarsely punctate ; intervals narrow, finely, uniseriately punctate.

CARPHOIVOTL'S n. geu.
A single species, boreal in habitat and partially pubescent, pos-
sesses several peculiarities of structure which appear to prevent its
assignment to any of the described genera.
Body moderately stout, somewhat depressed above, the elytra parallel, much
wider than the prothorax ; soutellum distinct, flat, ogival. Head short, the
beak straight, moderately short, parallel, not separated from the head by a
transverse impression. Antennae inserted a little beyond the middle, the
scrobes deep, obliquely descending beneath the eye ; scape moderate ; funicle
7-jointed, the basal joint stout, as long as the next two ; second to seventh
equal in length, but slightly wider than long, gradually a little thicker ;
club abrupt, moderate in size, the basal joint large, polished, sparsely setose.
Eyes on the sides of the head at their own length from the prothorax, not very
finely faceted, somewhat convex and prominent, transversely oval. Prosternum
separating the large anterior coxae by one-half of their own width ; interme-
diate coxse rather more than twice as widely separated as the anterior. Meta-
sternum long. Legs stout ; tibiae parallel, the external uncus well developed
but without trace of internal spur at aj^ex ; tarsi rather stout, the third joint
distinctly dilated and bilobed.
This genus is somewhat allied to Stenancylus, but differs in its
broader form, relatively narrower prothora.x, less prominent, more
finely faceted eN'es situated much nearer to the anterior margin of
the prothorax, shorter head, longer beak with the antennae inserted
beyond the middle, relatively less widely separated anterior coxa?,
absence of internal tibial spur, and in the hairy vestiture.
C. testaceilS n. sp. — Oblong-oval, feebly depressed above, pale rufo tes-
taceous throughout, smooth and polished, the upper surface with short coarse
and very sparse, subrecumbent pubescence, becoming erect toward the elytral
apices and somewhat bristling on the beak. Head and beak minutely but
strongly, not very densely punctate, the beak twice as long as the head and
three-fifths as long as the prothorax, viewed anteriorly nearly twice as long
as wide. Prothorax about as long as wide, feebly constricted near tlie apex ;
sides subparallel and very slightly arcuate ; apex broadly, feebly arcuate and
but slightly narrower than the base ; punctures rather fine but deep, perfo-
rate, somewhat sparse ; median line obsolete. Elytra one-half wider than the
prothorax and two and one-half times as long, twice as long as wide, parallel
and straight at the sides, obtusely ogival in scarcely more than apical fourth ;

APOTREPIJS n. gen.
A single species again constitutes a genus which is without any
close ally in our fauna.
Body stout, subcylindrical, moderately convex, the elytra wider than the
prothorax. the scutellum distinct ; upper surface setose. Head short, broad,
couo-globose, not conspicuously separated from the beak. Beak rather short,
robust, parallel toward base but dilated toward apex. Eyes situated at the
sides, partially on the beak, distant from the prothorax, feebly convex and
rather prominent, somewhat coarsely faceted. Antennae inserted at the
middle, the scrobes deep, linear, obliquely descending to the lo^rer limit of
the eyes ; scape robust ; funicle long, 7-jointed, the two basal joints equal,
each longer than wide and longer than three to seven, which are subequal
in length, gradually thicker, obconical, submoniliform, the articulations
strongly marked ; club oval, densely but coarsely pubescent, abrupt, fully
as long as the preceding four joints, not annulate. Anterior coxae small, re-
mote, separated by fully their own width ; intermediate still more widely
separated. Metasternum long. Legs rather long but somewhat stout, the
tibiae parallel, with a small internal spur and well-deveh)ped external uncus
at apex ; tarsi rather long, the basal joint nearly as long as the next two,
third feebly dilated, fourth but slightly longer than the preceding two com-
bined.
Apotrepus is related to CaiilojJiihis latinasiis perhaps more
closely than to any other North American species, resembling it
in general form of the body, but differing greatly in its shorter
beak dilated near the apex, in its smaller eyes, longer second funic-
ular joint, and in the sparse bristling and setiform vestiture.
A. deiisicollis n. sp. — Black, the antennae and legs feebly rufescent,
rather shining, the s*^tae short, stiff, erect, forming an uneven single line on
each elytral interval. Head very short, finely, sparsely punctate, the beak
nearly straight, densely, subrugosely punctate, more than twice as long as
the head and separated therefiom only by a very broad transverse impres-
sion, from the anterior margin of the eyes to the apex one-half as long as the
prothorax, not twice as long as wide viewed anteriorly. Prothorax about as
long as wide, broadly, strongly constricted behind the apex, the sides feebly

then gradually rounded convergent and sinuate to the apex; humeri right,
narrowly rounded ; strife coarse, feebly impressed, coarsely deeply and ap-
proximately punctate, the intervals about as wide as the strial punctures,
scarcely perceptibly punctate. Under surface rather coarsely, densely punc-

PSEUDOPE^TARTHRIJM Woll.
This genus was founded by Wollaston upon a small species from
Mexico, resembling Phloeophagus, and with the anterior coxa3 ap-
proximate as in that genus, but having the antenna! funicle 5-jointed.
It is distinguished from Pentarlhrum by its much less distant an-
terior coxae and more abbreviated cylindrical form. 1 now assign
to it two other species, having the beak very short, thick but parallel,
not constricted at base, though sometimes separated from the liead
by a l)road feeble transverse impression. Eyes moderately devel-
oped, feebly convex, finely faceted, situated at the upper part of the
sides and conspicuous from above; scrobes horizontal, deep, ending
at quite an appreciable distance in front of the eye and there flexed
abruptly downward. Antennae inserted at basal third, thick, the
basal joint of the funiele large, two to five transverse, parallel, sub-
equal, closely coarctate, the club continuous with the funicle, and,
together with joints two to five, strongly compressed. Scutellum
distinct. Metasternum rather long. Anterior coxae closely approxi-
mate. Legs short, robust, the tarsi stout with the third joint but
slightly wider than the second, the fourth not as long as the re-
mainder, arcuate and ver}^ slender.
Pseudopentarthrum differs from Pentarthrinus in its shorter, more
parallel form, relatively larger prothorax, in the greater distance
between the antennal scrobes and the e}e, in the more compact and
compressed antennae, with the club not abrupt, and in its stouter
legs. The species may be separated by the following characters: —
Beak not separated from the head by a pronounced transverse impression ;
larger species, the pronotum highly polished roblistlliu
Coleopterological Notices, IV. 697
Beak separated by a broad transverse impression ; head and basal parts of
the beak finely, remotely punctate, the remainder of the beak densely so ;
pronothm dull simplex
P. rolllistum n. sp. — Robust, cylindrical, the elytra perfectly parallel
and a little wider than the prothorax, polished, black and glabrous through-
out. Head rather finely but deeply, not densely punctate ; beak thick, finely
punctate, not separated from the head by a transverse impression, two-fifths as
long as the prothorax ; scrobes not extending to the eye, rectangular ; antennae
inserted at basal third, first funicular joint large, wider than long, rather
longer than the next two, second concealed partly within the apex of the first,
apparently shorter than the third, two to five coarctate, forming a thick com-
pressed mass, the club scarcely at all wider or thicker and forming nearly a
prolongation of the funicle. Prothorax about as long as wide, broadly rounded
on the sides, constricted behind the apex, the latter three-fourths as wide as
the base ; punctures coarse, deep, perforate, separated by about one-half of
their own diameters, with a polished impunctate central spot. Scutellum
rounded, slightly tumid. Eli/tra one-half longer than wide ; striae deeply
impressed, coarsely deeply and closely punctate ; intervals two to three times
as wide as the strial punctures, convex. Under surface coarsely, closely punc-
tate, the abdomen more sparsely so, and more finely, except at base. Length
3.7 mm. ; width 1.3 mm.

The single specimen is of undetermined sex.
P. simplex n. sp. — Cylindrical, moderately stout, black, glabrous, the
pronotum subalutaceous. Head very finely, sparsely punctate ; beak finely,
closely punctate except toward base, separated from the head by a rather deep
wide transverse impression, which is very sparsely punctate and minutely,
obsoletely foveolate, thick, parallel, as long as the head, not one-half as long
as the prothorax ; scrobes deep, rectangular, not attaining the eye by a very
noticeable distance; antenna inserted near basal third, nearly as in robusfum,
but witli the joints much less transverse. Protliorax nearly as long as wide,
feebly constricted behind the apex, the latter broadly arcuate and nearly four-
fifths as wide as the base; sides feebly arcuate ; punctures coarse, deep, sepa-
rated by much less than their own widths, without median impunctate area.
Elytra parallel, barely three-fifths longer than wide, nearly twice as long as
the prothorax and slightly wider ; striae deeply impressed, coarsely, deeply
but not very closely punctate ; intervals convex, finely, sparsely, subseriately
punctate, twice as wide as the strial punctures. Under surface not coarsely

PEBTTARTHRIIVUS n. gen.
I refer to this genus several species which have been previously
assigned to Amaurorhinus Fairm. Amaurorhinus, according to
Wollaston, has the scutellum obsolete, the eyes rudimentary or
obsolete, the elytra oval or fusiform, the antenna? inserted far
beyond the middle of the beak, and the metasternum short, all of
which characters are at variance with the species under considera-
tion. As represented by the four species in my cabinet, Pentar-
thrinus may be known by the following characters: —
Body feebly snbcmieiform, moderately convex, polished and glabrous, with
the scutellura distinct, metasternum elongate, anterior coxse approximate, and '
the intermediate separated by much less than their own width. Beak very
short, thick, parallel, longitudinally convex, separated from the head by a
very broad transverse impression. Eyes well developed, moderately convex,
at the sides of the head, distant from the prothorax and finely faceted.
Antennae inserted at basal third, in deep wide scrobes which are horizontal
nearly to the margin of the eye, then dilated or flexed downward ; scape short,
thick; funicle 5-jointed, the basal joint large, the others subequal in length,
obconical, wider than long, the articulations distinct; club abrupt. Legs
short and slender, the tarsi slender with the third joint but slightly dilated.
Pentarthrinus is quite closely related to Pentarthrum and Pseu-
dopentarthrum, but differs from the former in the more approximate
anterior coxae, and from the latter in the abrupt antenual club. The
species may be separated as follows: —
Anterior coxse extremely approximate but not in actual contact; beak not
impressed in basal half.
Pronotum rather coarsely deeply and conspicuously punctate, with the
interspaces highly polished.
Elytral intervals twice as wide as the strife, flat, minutely, very sparsely
and somewhat confusedly punctate in single series Ilitens
Elytral intervals narrow, not wider than the striae, each with a single
series of fine but distinct punctures, more oi- less confused on the sutural
interval ; pi-othorax small parvicollis
Pronotum slightly alutaceous, sparsely, less deeply and much more finely
punctate ; elytral intervals narrow, polished, strongly convex, with the
punctures of the single series remote, excessively minute and scarcely
discernable , piceus
Anterior coxae narrowly though quite perceptibly separated ; beak narrowly
impressed along the median line in basal half or more atrolucens
P. nitens Horn — Proc. Am. Phil. Soc, XIII, 1S73, p. 434 (Amaurorhinus ?).
Subcylindrical or feebly cuneate, moderately convex, just visibly

densely, punctate, the latter separated from the head by a broad,
shallow transverse impression which is rather deeply foveate in the
middle ; scrobes deep ; antennae inserted at basal third, the first
funicular joint larg-e, the club rather large, compressed, much wider
than the outer joints of the funicle, sparsely pubescent. Prothorax
scarcely as long as wide, feebly constricted and very briefly sub-
tubulate at base ; sides feebly convergent and broadly arcuate from
near the base, still more convergent but scarcely constricted near the
apex, the latter three-fifths as wide as the base; punctures strong,
sparse, without distinct median line. Elytra one-fourth wider than
the prothorax and two and one-half times as long, constricted near
the apex, the striae feebly impressed, rather coarsely and approxi-
mately punctate; intervals wide, flat, fully twice as wide as the
striae, very minutely punctate. Metasternum rather finely but
deeply punctate, closely and more coarsely so anteriorly, the abdo-
men finely and sparsely punctate. Length 3.3 mm. ; width 1.2 mm.

larger than the original type as measured by the author.
P. parTicollis n. sp. — Rather short and robust, subcuneate, convex,
glabrous, polished and black, the legs and antennae rufous. Head minutely,
extremely sparsely punctate, the beak throughout more coarsely deeply and
closely so, the punctures somewhat uneven ; front not in the least foveate ;
eyes well developed, situated midway between the apex of the prothorax and
end of the beak, the latter robust, very short, less than one-half as long as
the prothorax, the antennae inserted at basal third. Prothorax small, oval,
strongly convex, about as long as wide, the sides evenly and strongly arcu-
ate, a little more convergent anteriorly but not in the least constricted ; apex
three-fourths as wide as the base ; punctures coarse, deep but not dense,
somewhat uneven in distribution but generally separated by rather more
than their own widths ; median line obsolete. Elytra two-thirds wider than
the prothorax and nearly three times as long, rather short, not twice as long
as wide, very slightly wider behind than at base, obtusely ogival but not
constricted in apical fourth or more ; sides just visibly arcuate ; humeri
broadly exposed but rounded ; striae feebly impressed, very coarsely but not
approximately punctate, the intervals narrow. Abdomen finely, sparsely
punctate, the metasternum coarsely and more closely so. Length 2.1-2.5

evidently a widely different species, with the " lateral striie entire ;"
in F. parvicolHs, the ninth and tenth striae are united behind the
humeri, as in all the species of this genus.'

the elytra polished ; pronotum feebly aliitaceous and minutely reticulate.
Head and beak minutely and sparsely punctate, the latter parallel, convex,
one- half as long as the prothorax, separated from the head by a broad, trans-
verse impression, which is foveate in the middle ; aerobes deep, widening be-
hind ; antennae inserted behind the middle, tlie basal joint of the fanicle
large, two to five transversely obconical, subequal in length, the second par-

Florida.
One specimen, apparently a female. The head is not much more
sparsely punctate than the beak, but is almost impunctate toward
base and has a small, feebly impressed frontal fovea This species
may be known at once by its fine punctuation and piceous-brown
color.
P. atrolticens n. sp. — Narrow, feebly cuneate, strongly convex, pol-
ished, black and glabrous throughout, the legs slightly piceous, the apical
margin of the prothorax feebly rufescent. Head and basal half of the beak
finely and very sparsely punctate ; beak longitudinally, convex, very short,

median line obsolete. Elytra a little wider behind, nearly one-third wider
than the prothorax and more than twice as long, three fourths longer than
wide ; sides nearly straight, rounded, convergent and feebly constricted in
apical third, the apex narrowly subtruncate ; striae coarse, feebly impressed,
the punctures coarse, rounded but not very close-set ; intervals nearly flat,
feebly elevated, but slightly wider than the strial punctures, each with a
single series of fine but distinct punctures. Metasternum coarsely and closely
punctured, the abdomen more finely and sparsely so. Length 2.3-2.6 mm. ;
width 0.7-0.9 mm.
Florida (Biscayne Bay).
This species differs from nitens in its smaller size, narrower form,
coarser strise, larger punctures, sculpture of the beak, and rather
more widely separated anterior coxge ; from piceus it may be known
at once by its color, more polished surface, and very much more
coarsely punctured pronotum. Three specimens.
NYSSONOTUS n. gen.
The principal characters distinguishing this pentarthride genus
may be stated as follows : —
Body cylindrically convex, deeply and closely sculptured, setose. Beak
thick, short, parallel, arcuate toward apex, not separated from the head by
a transverse impression. Antennse inserted a little behind the middle, the
scrobes deep, beginning beyond the middle, thence straight and feebly de-
scending nearly to the lower limit of the eye, thence abruptly transverse
beneath ; scape short, a.s long as the first three joints of the fuuicle, the latter
5-jointed, the basal joint large, two to five feebly obconical, subequal, a little
wider than long; club abrupt, compressed, oval, with the basal joint large.
Eyes moderate, rather finely faceted, subdepressed, at the sides of the head
and very remotely separated. Scutellum distinct. Metasternum long. An-
terior coxae extremely approximate, the intermediate rather widely separated.
Legs nearly normal, external tibial uncus well developed, the anterior also
with a short internal terminal spur ; tarsi short, thick, the third joint slightly
dilated, deeply emarginate, the fourth slender, fully as long as the preceding
three together.
Nyssonotus is closely allied to Pseudopentarthrum, but diflers in
the obliquely descending and not horizontal antennal scrobes, in
the longer beak, still more widely separated and lateral eyes, and
in the stiff erect and bristling setae.
N. seriatUS n. sp. — Cylindrical, feebly shining, black, the upper surface
throughout with very short erect stifi" setae, sparsely placed but forming a
T02 Coleopterological Notices, IV.
single close-set series on eacli elytral interval. Head and beak strongly,
rather closely punctate, convex, without frontal fovea ; antennse feebly rufes-
cent, sparsely setose. Pi-othorax not quite as long as wide, the sides broadly,
feebly arcuate, gradually slightly convergent and not constricted to the apex,
strongly arcuate near the base, the latter slightly wider than the subtru'ncate
apex ; punctures coarse, deep, extremely dense, without median line. Elytra
parallel and straight at the sides, three-fifths longer than wide, distinctly
wider than the prothorax and more tlian twice as long ; humeri right, not
prominent, narrowly rounded ; apex broadly, evenly parabolic, the sides not
constricted; disk with feebly impressed series of coarse, rounded, approxi-
mate punctures, the intervals fiat, equal in width to the strial punctures,
each with a single series of much smaller but strong and conspicuous setiferous
piinctures. Abdomen coarselj^ closely and subrugosely punctate, the meta-
sternum more finely but rather densely so. Length 3.0-3.3 mm. ; width
1.1 mm.
Texas (El Paso). Mr. G. W. Dunn.
This species somewhat resembles a rather stout Rhyncolus, and
may be easily identified otherwise by the coarse, dense sculpture,
and erect setse. Three specimens.
RHAHPHOCOLUS n. gen.
Body narrowly cylindrical, glabrous, shining. Head very short, merging
gradually into the beak, the latter short, gradually wider from apex to base,
not separated from the head by a tj'ansverse impression. Eyes almost flat,
but well developed, oval, rather finely faceted, situated at the lower part of
the sides of the head, not very distant from the prothorax and but slightly
visible from above. Antennae inserted at basal third, the scrobes narrow,
straight, gradually descending and directed upon the middle point of the
eye ; scape slender, feebly clavate ; funicle T-jointed, the basal joint stouter,
as long as the next three, two to seven wider than long, subequal in length,
gradually wider, the articulations distinct ; club abrupt, moderate in size,
oval, annulate toward apex. Anterior coxse narrowly separated, the inter-
mediate separated by much less than their own width. Metasternum rather
long. Legs somewhat short, the femora stout ; tibiae slender, very minutely
uncinate within at apex, the external uncus distinct ; tarsi slender, the third
joint completely undilated, not at all wider than the second. Scutellum dis-
tinct.
The form of the beak and several other structural characters
show that Rhamphocolus must be associated with Rhyncolus, but it
differs notably from that genus in its much less convex and more
inferior eyes, with the antennal scrobes directed upon them and
not below them, in its more slender tarsi and still more approxi-
mate anterior coxae.
Coleopterological Notices, IV. 703
R. tenuis n. sp. — Narrowly cylindrical, convex', black, the legs and an-
tennae dark brown ; integuments polished and glabrous. Head and beak
finely, rather sparsely punctate, the latter feebly conical, three-fifths as long
as the prothorax, one-half longer than wide.^ Prothorax very nearly as long
as wide, broadly, just visibly impressed behind the apex ; sides feebly con-
vergent and nearly straight from before the base to the apex, the latter
broadly arcuate, subequal in width to the basal margin ; punctures coarse,
deep, rather close-set and uneven, without median line. Elytra but very
slightly wider than the prothorax and scarcely more than twice as long,
twice as long as wide, the sides parallel and straight nearly to apical fourth,
then convergent and nearly straight to the narrowly rounded apex ; humeri
angulate and somewhat anteriorly prominent ; disk with feebly impressed
series of coarse deep rounded and close-set punctures, the intervals flat,
barely as wide as the striae, each with a single series of fine bnt distinct,
rather remote punctures. Under surface rather coarsely but feebly and not
densely punctate. Length 2.1-2.3 mm. ; width 0.6-0.7 mm.
Texas (Austin).
Readily recognizable by its resemblance to an unusually slender
Rhyncolus.
RHYWCOLUS Germ.
The species of this genus vary greatly among themselves, espe-
cially in the structure of the antennae and the degree of separation
of the anterior coxae. The following descriptions will indicate some
of these discordances.
R. palleilS n. sp. — Cylindrically convex, shining, pale flavo-ferruginous
throughout, the head, beak and apical parts of the prothorax piceous-blaeik.
Head and beak minutely, the latter rather closely, punctate, impressed along
the middle, conical, extremely short, much wider than long and shorter than
the head ; eyes_ small, rounded, prominent ; antennae moderate, the scape
nearly as long as the funicle, with one or two stiff erect setae on the under
surface, the fnnicle slender with the second joint obconical, as long as wide
and longer than the third, club abrupt, oval, densely pubescent and about as
long as the five preceding joints combined. Prothorax a little wider than long,
feebly constricted behind the apex, the latter as wide as the base ; sides feebly
convergent from before the base to the apex and nearly straight ; disk very
finely closely punctate, without entire median line. Elytra but slightly wider
than the prothorax and more than twice as long, twice as long as wide ; sides
straight ; apex obtusely rounded ; disk with almost entirely unimpressed series
of fine, rounded, approximate punctures, the series impressed on the apical
declivity and the fifth also toward base ; intervals flat, minutely punctate in

face very finely, densely punctate, the abdomen evenly but less densely so,
the first suture deep throughout, broadly angulate in the middle. Anterior

width 0.75-0.9 mm.
California (San Francisco).
This i.« the commonest species of the middle coast regions, and is
not closely allied to any other. It is represented by a large series.
R. spretUS n. sp. — Cylindrical, shining, dark rufo-piceous, the occiput,
legs and antennal club paler, rufous. Uead almost impunctate toward base ;
beak finely but strongly, densely punctate, very short, wider than long,
scarcely as long as the head, conical, narrowly impressed along the middle ;
eyes well developed, moderately prominent ; antennae inserted just before the
eyes, the scape not quite as long as the funicle, swollen and setose near the
middle beneath as in pallens, funicle moderately slender, the second joint a
little wider than long and but slightly longer than the third, club abrupt,
oval, nearly as long as the preceding five joints. Prothorax slightly wider than
long, the sides very feebly convergent and straight from before the base to the
subapical constriction, which is pronounced but not abrupt ; apex scarcely as
wide as the base; disk very finely, closely punctate, without impunctate line.
Elytra not distinctly wider than the prothorax and about twice as long, three-
fourths longer than wide, parallel and straight at the sides, obtusely rounded
at apex, the disk with scarcely at all impressed series of large, shallow,
rounded and well separated punctures, the intervals nearly flat, not wider than
the strial punctures, each with a single series of minute remote punctures.
Prosternum finely, densely punctate, the metasternum and abdomen toward
base finely but more sparsely so ; fifth segment finely, extremely densely punc-
tate and dull. Anterior coxae separated by barely one-fourth of their own
width. Length 2.3 mm. ; width 0.8 mm.
California.
Related to angularis Lee, but with shorter prothorax and elytra,
the serial punctures of the latter being larger, more distant and less
deeply impressed, the pronotum is much more finely and closely
punctate, and the beak is impressed in the middle. The first ab-
dominal suture is deeply impressed and nearly straight. A single
specimen.
R* dilata.ttlS n. sp. — Cylindrical, robust, polished, dark rufo-piceous,
the legs and antennal club paler. Head sparsely but strongly, the beak more
finely but rather densely, punctate, the latter nearly as long as wide, conical,
a little longer than the head, feebly impressed or flattened and less densely
punctate along the middle ; eyes small, rather feebly convex, situated much
nearer the prothorax than the tip of the beak ; antennae inserted just behind
the middle, the scape long but not quite as long as the funicle, gradually,
strongly clavate, funicle cylindrical, the basal joint rather more robust and
as long as the next two, second distinctly wider than long and barely longer
than the third, club rather abrupt but not longer than the four preceding

joints, oval. Prothorax about as long as wide, the sides very feebly con-
vergent and straight from before the base to apical third, then gradually a
little more convergent to the apex, which is four-fifths as wide as the base;
constriction fine and feeble ; disk rather coarsely, very deeply and somewhat
unevenly punctate, the punctures separated by about their own diameters,
without impunotate line. Elytra short, just visibly wider and barely two-
thirds longer than tlie prothorax, one-half longer than wide ; sides parallel
and straight, the apex semi-circularly rounded ; disk with coarse, rather
deep, coarsely and profoundly punctate stripe, the intervals narrow but
nearly flat, scarcely more than one-half as wide as the strise, each with a
single series of fine remote punctures. Under surface densely punctate, the
abdomen more sparsely so, the fifth segment closely. Anterior coxse large,
separated by rather less than one-third of their own width. Length 3.0 mm. ;
width 1.05 mm.
California.
The type to which this isohited species is referable, differs from
that of pallens and spretus very greatly in the antennal scrobes,
which, in those species, are basal and nearly transverse ; in dila-
tatus they begin near the apex of the somewhat longer beak, de-
scending thence obliquely beneath the eye ; the scape, also, is
gradually and evenly clavate in dilatatus, and not swollen in the
middle beneath, and the head is shorter with the eyes less remote
from the prothorax. The first ventral suture is deep and straight,
the next two extremely coarsely excavated but straight. One
specimen.
R. relictllS n. sp. — Ovo-cylindrical, dark piceous-brown, the tarsi and
antennal club paler. Head very minutely, sparsely, the beak more strongly,
rather densely, punctate, the latter as long as the head, nearly as long as
wide, parallel and straight at the sides and distinctly impressed along the
middle ; eyes situated neai-ly midway between the prothorax and tip of the
beak ; antennae moderately long, the scrobes narrow, obliquely descending,
scape gradually thick and clavate, inserted at basal third, distinctly shorter
than the funicle, the latter rather slender, the second joint longer than the
third, outer joints thicker, club distinctly wider, oval. Prothorax one-third
longer than the head and beak, fully as long as wide, widest at basal third
where the sides are broadly arcuate, thence feebly convergent and nearly
straight to the apex, which is just visibly narrower than the basal margin ;
constriction feeble ; disk finely, not very deeply, somewhat unevenly and not
densely punctate, generally with a feebly defined median impunctate spot.
Elytra one-fifth wider than the prothorax and fully twice as long, not quite
twice as long as wide ; sides straight and parallel, convergent and constricted
in apical third, the apex somewhat produced and narrowly, almost seuii-circu-
larly rounded ; disk with impressed series of rather large, very deep, well-
separated punctures, the intervals feebly convex, barely one-half wider than

the strije, each with an uneven series of extremely minute distant punctures.
Under surface not very coarsely but deeply and densely punctate, the abdo-
men more sparsely so except on the fifth segment ; first suture very fine,
broadly curved throughout and just traceable, the other three very coarse
and deep anterior coxae separated by barely one-third of their own width.
Length 2.8-3.4 mm. ; width 0.8-1.1 mm.
New Mexico.
This species shares to some extent the characters distinguishing
both the pallens and oregonensis types of the genus, having the
somewhat longer uncontractile second funicular joint and the oval
and wider club of the former, and the fine and feeble first abdo-
minal suture of the latter. In oregonensis the club is but very
slightly wider than the tip of the funicle, and the eyes are larger,
more circular and decidedly nearer the apex of the prothorax. The
beak in relictus is somewhat aberrant in being parallel and not
conical.
R. Iliinius n. sp. — Cylindrical, moderately stout, polished, black through-
out, the tarsi and antennal club paler. Head very minutely and sparsely
punctate, the beak more coarsely deeply and rather densely so, just visibly
and unevenly subimpressed along the middle, conical, about as long as the
head and nearly as long as wide ; eyes rather large, very convex, finely
faceted as usual, situated at a little more than their own length from the
prothorax ; antennje short and very thick, aberrant, inserted at basal third,
scrobes deep and coarse, beginning at apical third and rapidly obliquely de-
scending, scape short, thick, the funicle very thick, cylindrical and equal in
diameter from the second joint to the widest part of the club, the basal joint
a little thicker, wider than long, with its apex excavated, the second joint
deeply received in the cup-like excavation and having only a very short
apical margin exposed beyond it ; joints two to seven short, extremely trans-
verse but somewhat compactly perfoliate, each joint being deeply concave at
apex ; club not in the least wider, scarcely longer than the three preceding
joints combined. Prothorax a little longer than wide, the sides broadly,
almost evenly arcuate, gradually convergent anteriorly, the constriction dis-
tinct ; apex broadly arcuate and a little narrower than the base ; disk
coarsely, deeply but rather sparsely punctate. Elytra not wider than the
prothorax and scar(;ely more tlian three-fourths longer, not quite twice as
long as wide; sides straight, apex broadly, obtusely rounded throughout,
not at all constricted ; disk coarsely, deeply subsulcate, the grooves coarsely,
deeply punctate ; intervals about as wide as the sulci, each with a single
series of fine remote punctures. Metasternura rather finely but closely punc-
tate, the abdomen but slightly more sparsely so. Anterior coxae large, sepa-
rated by scarcely one-fifth of their own width. First ventral suture broadly
arcuate, very fine, not impressed. Length 4.7 mm. ; width 1.3 mm.
Coleopterological Notices, IV. 707
New Mexico (Las Vegas).
The single specimen is probably a male, the abdomen having
near the base, an elongate-oval, feeble impression, which is finely,
extremely densely punctate and coarsely pubescent. This is one
of the largest species of the genus.
R. discors n. sp. — Narrowly cylindrical, black and polished; legs and
antennae paler, dark riifo-testaceous. Head minutely, remotely punctate
toward base, rather longer than the beak, which is feebly conical, densely
punctate, not impressed and wider than long ; eyes rather small but strongly
convex and prominent ; antennse moderately thick, the basal joint of the
fiinicle more robust, excavated at apex and enclosing the second, with the
exception of a short apical margin, two to six subequal, strongly transverse,
compactly perfoliate, the seventh rather longer and wider, obconical ; club
wider than any joint of the funicle but not abrupt, oval, with its basal joint
composing one-half the mass, polished and sparsely setose, the remainder
densely pubescent. Prothorax fully as long as wide, the sides very slightly
convergent and nearly straight from just before the base to the apex, the
constriction fine and very feeble ; apex broadly arcuate and about as wide as
the base ; disk coarsely, deeply, moderately closely punctate, with a wide
impunctate spot in basal two-thirds. Elytra not distinctly wider than the
prothorax and not quite twice as long, scarcely twice as long as wide, the
sides straight ; apex evenly obtusely and semi-circularly rounded ; disk very
coarsely, deeply sulcate, the grooves strongly punctate ; intervals not quite
as wide as the sulci, each with a single series of small, very remote piinc-
tures. Under surface rather coarsely deeply and densely punctate, the
abdomen scarcely more sparsely so ; first suture straight, very fine, not
impressed. Anterior coxae not large, separated by one-fifth of their own
width. Length 2.8-3.0 mm. ; width 0.8 mm.
Florida.
Allied in antennal structure to nimius, but differing greatly in
its small size and more slender form ; the antennal club is rela-
tively thicker than in nimius and the funicle gradually thicker
toward apex. If the antennal funicle of these two species were not
examined with great care, it would surely be pronounced 6-jointed,
so thoroughly is the second joint hidden within the apex of the
first.

APPENDIX.
I.
The following remarkable genus was received too late for inser-
tion in its proper place among the tribes discussed in the present
paper : —
SCHIZOIVOTUS 11. gen. (Erirhiiiini).
Body narrow, snboval, elongate and moderately convex above, the pro-
thorax flexed downward. Head deflexed, deeply inserted, not visible from
above. Eyes completely wanting. Beak nearly straight, bent slightly at
apex and separated from the head by a distinct transverse impression. An-
teiinfe inserted at apical third, the sci'obes inferior, bounded along their upper
margin by an acutely elevated carina ; scape robust, gradually claviform,
attaining the under surface of the head ; funicle 7-jointed, joints two to five
gradually decreasing in length, the second rather elongate but not quite as
long or thick as the first, outer joints but slightly thicker ; club well devel-
oped, abrupt, elongate, ovo-conoidal, gradually pointed, densely pubescent,
the distinct sutures marked by dense recumbent lacinise. Prothorax oval,
very oblique laterally at apex, transversely truncate at base, broadly, feebly
constricted near the apex. Scutellum exceedingly minute. Elytra apparently
connate, broadly, evenly emarginate at base, the latter not receiving the base
of the prothorax. Prosternum rather long, sinuate at apex, broadly, deeply
excavated along the middle, the sides of the sulcus acutely elevated. Meso-
and metasterna extremely short. Abdomen very long, flat, the first two seg-
ments long, separated by a very fine arcuate suture ; third segment short,
the second and third sutures coarse and deeply impressed ; fourth segment a
little longer than the third, separated from the fifth by a very fine straight
and almost obsolete suture ; fifth segment much longer than the two preceding
combined. Legs short but extremely robust, the femora stout, almost straight
along the lower margin ; tibife very broadly triangular, strongly compressed,
partially fimbriate at apex ; tarsi attached at the inner angle of the tibife,
short, flattened, the subbasal joints transverse, the third but feebly dilated,
fourth very short, scarcely one-half longer than wide, received for about one-
half its length in the apical emargination of the third joint ; claws rather
long, slender, free, divergent and simple.
• This genus is closely related to the European Raymondionymus
Woll. — which appears to constitute a subgenus of Alaocyba, — so
Coleopterological Notices, IV. 709
closely indeed, that if Wollaston (Trans. Ent. Soc. Lond., 1873)
did not repeatedly state that the antennal funicle in that genus is
fi-jointed, I should be inclined to regard them as identical.
Besides the entire lack of eyes, thick fossorial legs, deeply ex-
cavated and bicarinate prosternum, excessively short sterna of
the hind body and very elongate abdomen, with the fourth suture
fine and almost obsolete, Schizonotus is remarkable in having the
deflexed prothorax non-conformable with the elytra at base, the
base of the former being truncate or even apparently somewhat
sinuate, while that of the latter is deeply emarginate, the two bases
being always widely separated and exposing a large part of the
mesonotum.
It is not altogether surprising that Wollaston made the mistake
of assigning these genera to the Cossonina?; they certainly have a
cossonide facies in some respects. The rostral, antennal, and pro-
sternal characters, however, prove them to be aberrant members of
the bagoide series.
S. caPCUS 11. sp. — Rather dark red-brown throughout, polished, sparsely
covered with short pale bristling setje, which form single series on the elytral
intervals. Head finely, the beak more coarsely, sparsely punctate through-
out, the beak not quite as long as the prothorax, inflexed in direction, making
an acute angle with the plane of the elytra. Prothorax rather longer than
wide, the sides broadly arcuate, constricted at the sides just before the basal
margin, the apex broadly arcuate and scarcely three-fifths as wide as the base ;
disk perfectly even, feebly convex above, finely but deeply, very sparsely
punctate, without median line. Elytra elongate-oval, more than twice as
long as wide and two and one-half times as long as the prothorax, in the
middle nearly one-half wider than the latter ; sides parallel and nearly
straight in the middle, convergent and rounded toward base, convergent and
straight or feebly sinuate in apical third, the apex narrowly rounded ; basal
margin acute laterally ; disk with unimpressed series of rather small but
deep, somewhat distant punctures, becoming coarse and deep on the inflexed
flanks ; punctures of the intervals toward the suture nearly as large as those
of the series, the latter becoming almost obsolete toward apex. Abdomen very
sparsely punctate but strongly so toward base. Length 2.0-2.1 mm. ; width
0.7-0.75 mm.
California.
A most interesting species, apparently the only completely blind
curculionide thus far recorded from North America ; as might have
been anticipated it has revealed itself in the subasiatic fauna char-
acterizing our Pacific Coast.

The two specimens in my cabinet were kindly communicated by
Mr. Chas. Fuchs, who discovered them while sifting mouldy earth
amonii- the red-woods north of San Francisco.
II.
CYCLOSATTUS n. gen. (Tenebrionidse).
The species which I described under the name Eusaftus websteri
(Col. Not., Ill, p 5fi) has the outline and general habitus of cer-
tain forms of Eusattus, but was placed in that genus without due
examination of its generic characters; these I find to be very dif-
ferent, and, in order that the species may be understood, it is neces-
sary to refer it to a new genus far removed from the Coniontini.
It forms the second of the only two known North American generic
types of the tribe Opatrumini (Col. Not., II, p. 391), the other one
being Ephalus Lee. The principal characters may be given as
follows : —
Bofly very broadly, evenly oval, rather strongly convex, the margins of
the pronotum broadly, and of the elytra narrowly, reflexed. Head promi-
nent at the sides before the eyes, transversely truncate at apex. Eyes trans-
verse, emarginate at the middle. Anterior, intermediate and posterior coxse
equally and not very widely separated, the abdominal process narrow and
obtusely angulate at apex. Legs not very long but slender, the anterior
tibiae with an externally produced apical process, the internal spur very
minute ; intermediate and posterior with two small slender terminal spurs.
Tarsi slender, short, slightly compressed, coarsely pubescent beneath, the
basal joint of the posterior not quite as long as the remaining three combined.
Elytra widely embracing the body, the epipleurse very wide, especially toward
base. Third and fourth abdominal sutures fine, vertical and coriaceous.
On examination of the under surface the epipleuras appear at
first to attain the elytral apices, but this is not so in reality, the
portion attaining the sutural angles being the narrow reflexed
margin of the elytra, the plane of the under surface of which
makes a strongly marked angle with that of the epipleurte proper,
throughout the entire extent.
Mr. F. Blanchard of Lowell, to whom I am indebted for calling
my attention to the fact that luehsteri could not be retained in
Eusattus, tells me that Dr. Levette found this specimen at Pueblo,
Colorado, but whether collected there or otherwise obtained he is
unable to state. I see no reasonable grounds for doubting its
Coleopterological Notices, IV. Ill
North American origin, however, as it is no more out of harmony
with the general tenebrionide fauna which surrounds it than the
monotypic Ephalus of the Atlantic States.
III.
LIPAROCEPHALUS Makl.
It is somewhat singular that the true affinities of this genus
should have so long escaped observation, especially as its entire
lack of harmony with all other types of Psederini is so strikingly
evident. Liparocephalus is a typical but highly specialized member
of the tribe Aleocharini, belonging near Phytosus, and having the
tarsal joints 4-4-5 in number.
IV.
Synonymical Notes.
In the Revision of the Stenini of America North of Mexico
(Philadelphia 1884), I have created a considerable number of
synonyms, these becoming evident from time to time as more
extended series were compared with the somewhat meagre mate-
rial which served as the basis of that memoir. A small part of the
synonymy has already been given by M. Fauvel, and I now take
pleasure in bringing forward as much as I have been able to ob-
serve from recent studies.
S. rugifer Cas. = anastomozans Cas. This is another interesting example
showing the correspondence between the arctic fauna of the summit of Mt.
Washington and that of the Rocky Mts.
S. vexatus Cas. = insularis Cas.
S. placidus Cas. = tumicollis Cas.
S. villosus Cas. =jejunus Cas.
S. milleporus Cas. = sectilifer Cas.
S. difficilis Cas. = tenuis Cas.
S. nanus St. =namdus Cas. The eastern pus/o Cas. is an allied but appa-
rently distinct species, of narrower form and much larger head.
S. humilis Er. = mammops (Jas.
S. rigidus Cas. = ageus Cas. The European argus is somewhat allied, but is
much narrower, more parallel and less fusiform, with the abdominal segments
decreasing less rapidly in width.
S. brumalis Cas. ( 9 ) = pauperculus Cas. (%)
S. gratiosus Cas. = Idrsutus Cas.

Tlie species in the neighborhood of morio Grav. are very much confused, and,
in my efforts to view a typical specimen from Europe, I have received four
distinct species, in one or two cases differing radically in male sexual charac-
ters. The following synonymy is however sufficiently evident : —
S. morio Grav. = indistinctus and haplus Cas.
The type of subgriseus represents a species quite different from morio, in the
abruptly very narrow sixth ventral segment and other characters.
S. umbratilis Cas. =fraternus Cas.
S. pollens Cas. = patens Cas.
S. reconditus Cas. = propinquus Cas. This species is stouter than the
European tarsalis, and has the punctuation stronger and coarser ; it also
differs in male sexual characters. The differences become quite evident with
the large series of both these species which I have before me. Canadensis is
closely allied but has much shorter elytra.
S. callosns Er. = varipes Cas.
S. punctatus Er. = dilutux and ohsoletus Cas.
S. hubbardi Cas. = simiolus Cas.
S. lucidus Cas. = leciceps and politulus Cas.
