LeConte.] 428 [Feb. 1, 
Though not belonging to the same zodlogical 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- 
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 JM. oculata, to which it is allied. 
134. Mordella obliqua, n. sp.—Black, pubescent. Head 
cinereous, prothorax with scattered cinereous hairs, and two 
indistinct vittee 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 cinercous. Beneath black ; anal process long and slen- 
der. Length 4mm.; .16 inch. 
Maryland, Dr. Zimmermann; Detroit, Michigan, Mr. E. 
A. Schwarz. In form and size this species resembles J. 
marginata. It is possible that J. /unulata Helmuth (Proce. 
Ac. Nat. Se. Phila. 1865, 96), 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- 
rewed 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 it 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 fovee, interspaces not costate at base, but the 
3d and 5th become gradually acute behind the middle; 7th acute for the
