Though not belonging to the same zoological province, the 
two following species may be conveniently described here: 
133. Mordella jovialis, n. sp.—Black, pubescent, with the mar- 
gins of the prothorax cinereous pubescent. Elytra densely cinereous pub- 
g ey escent with black markings as follows : two small spots near the 
base, the outer one elongate, the inner one round ; a transverse 
broad band at the middle, divided by a cinerous sutural line, the 
anterior outline of this band is nicked outside of the middle, and 
then runs obliquely forwards, almost to the side margin, which is 
cinereous ; the apical fourth is also black, divided almost to the 
tip by the cinereous sutural line. Beneath thinly clothed with pruinose 
cinereous pubescence, ventral transverse bands and hind coxe blackish. 
Length 4.7 mm.; .19 inch. 
Bosque County, Texas, G. W. Belfrage; one specimen. 
Of the same form and size as M. oculata, to which it is allied. 
134. Mordella obliqua, n. sp.—Black, pubescent. Head 
cinereous, prothorax with scattered cinereous hairs, and two 
indistinct vitte more densely cinereous. Elytra with a very 
narrow sutural line, and an oblique stripe from the humeri to 
beyond the middle, where it becomes obsolete, cinereous. Scu- 
tellum cinereous. Beneath black; anal process long and slen- 
der. Length 4 mm.; .16 inch. 
Maryland, Dr. Zimmermann; Detroit, Michigan, Mr. E. 
A. Schwarz. In form and size this species resembles M. 
marginata. It is possible that M. lunulata Helmuth (Proc. 
Ac. Nat. Se. Phila. 1865, 98), may have been a specimen of 
this species, with the elytral vitta partly effaced. The type 
has, I believe, been destroyed. 
135. Conotrachelus ventralis, n. sp.—Not robust; elytra nar- 
rowed behind from the base, humeri not dentiform.  Blackish-brown, 
thinly clothed, but scarcely mottled with coarse pale yellowish hairs. 
Beak half as long as the body, slender, brown, shining, sparsely punc- 
tured, striate each side for more than one-half the length. Antenne in- 
serted about one-third from the tip. Head strongly punctured, pubescent. 
Prothorax as long as wide, widest at the base, gradually narrowed and 
slightly rounded on the sides to the apex, near which st is feebly con- 
stricted ; very deeply, coarsely and densely punctured, elevated, dorsal 
line very narrow, indistinct. Elytra at base about one-half wider than 
the prothorax, humeri rounded, acutely margined, prominent, sides ob- 
liquely converging behind ; fully one-half longer than the width at base, 
striate composed of large foves, interspaces not costate at base, but the 
3d and 5th become gradually acute benind the middle; 7th acute for the 
1878.] 429 
[LeConte. 
whole length, united in front at a sharp angle with the 9th, which is also 
acute for its whole length, the two united then form the humeral margin. 
Beneath, inflexed flanks of prothorax densely, metathorax more coarsely 
but sparsely cribrate ; ventral segments very shining, with a few scattered 
large punctures, more numerous on the 5th. Legs long, thighs strongly 
unidentate, not annulat «.. Length 6 mm.; .25 inch. 
Enterprise; one specimen. Quite different from any other 
in our fauna; it should be placed after C. crategi, (vide Lec. 
and Horn, Rlıynch., 230), between 1-Ba and 1-Bb. 
196. Conotrachelus cognatus, n. sp. —Blackish ; elytra mottled 
with dull fulvous ; pubescence short, irregularly condensed. Head punc- 
tured, pubescent. Beak not half as long as the body, rather slender, very 
slightly curved, not shining, strongly striate. Antenne inserted less than 
one-fourth from the tip. Prothorax wider than long, sides strongly 
rounded in front, nearly straight near the base ; constricted near the apex ; 
very coarsely and densely cribrate, not carinate. Elytra one-half wider 
than the prothorax at the base, oblong, rounded behind, humeri rounded ; 
strie composed of large quadrate punctures, interspaces narrow, not. flat, 
9d, 5th and "7th acutely but not strongly costate ; 9th acute from the 
middle to within a short distance from the tip; at the base of the 3d inter- 
space is a small spot of white scales. Beneath, mesosternum prominent, 
metasternum cribrate ; ventral segments sparsely, 5th more densely punc- 
tured, impressed near the tip. Legs long, thighs unidentate, with a ring 
of gray pubescence. Length 4.3 mm.; .17 inch. 
Tampa; one specimen. This species has the mesosternum 
produced into a small process in front, as in C. posticatus, 
from which it differs chiefly by the prothorax being not 
carinated, and by the somewhat less robust form. 
137. Conotrachelus pusillus, n. sp. —Similar tothe preceding, but 
very much smaller, blackish-brown, with irregularly condensed pubescence ; 
elytra mottled with dull fulvous. Head punctured, yellow pubescent ; 
beak longer than head and prothorax, stout, curved, deeply striate. An- 
tenne inserted one-fourth from the end, brown.  Prothorax wider than 
long, rounded on the sides, broadly constricted near the apex, densely and 
coarsely punctured, not carinate. Elytra nearly one-half wider than the 
prothorax at base, oblong-oval, humeri rounded ; striz composed of large 
punctures, interspaces not so narrow as in C. cognatus, 9d, 5th and "th 
moderately carinate ; 9th carinate behind the middle. Beneath coarsely punc- 
tured; 5th ventral broadly impressed, mesosternum protuberant. Legs 
long, thighs unidentate, obsoletely annulated. Length 2.5 mm.; .10 inch. 
"Enterprise; one specimen. This is one of our smallest 
species.
