any other species in my collection, and easily known by the 
deeply and broadly suleate prothorax; the anterior trans- 
verse impression is broad and deep, and there is a broad dis- 
coidal impression each side near the base. 
140. Acalles subhispidus, n. sp.—Blackish, densely clothed with 
dark scales, which are larger on the prothorax than on the elytra, where 
they are intermixed with short, reclinate bristles. Prothorax wide, strongly 
rounded on the sides in front, coarsely punctured, with a narrow, lateral 
line, and a few scattered scales pale dirt color; disc not carinate. Elytra 
but little wider than the prothorax, base truncate, basal angles obtuse, dis- 
tinct, sides broadly rounded, then obliquely narrowed to the apex; very 
little wider behind the base, strize coarsely punctured, interspaces slightly 
convex ; there are traces of two narrow undulated bands, composed of 
small spots of gray scales, one before the middle, curving backwards 
towards the sides, the other behind the middle, curving forwards. Mesos- 
ternum deeply emarginate. Length 3.7 inm.; .15 inch. 
Sumter County; May, one specimen. Easily known from 
our other species by the shorter reclinate bristles of the 
elytra. The prothorax is larger, and the elytra less rounded 
on the sides. 
141. Cryptorhynchus helwus, n. sp.—Very similar to C. obliquus 
and differing only in the following characters: Scales pale yellow-brown, 
slightly variegated with darker; form of body a little narrower. Prothorax 
a little longer than wide, sides obliquely narrowed from the middle, where 
they are rounded to the apex, nearly parallel behind the middle. Elytra 
with the interspaces wide and flat. Thighs with one small acute tooth. 
Length 7.8 mm.; .31 inch. 
Enterprise ; May, one specimen. Except for the difference 
in the form of the prothorax, I should consider this as 
merely a variety of C. obliquus. The elytra are similarly im- 
pressed. 
142. Barilepton bivittatum, n. sp.—Very elongate, black, 
shining, with a broad vitta of white scales each side, beginning at the front 
margin of the prothorax, and extending to the tip of the elytra. Head 
sparsely and finely punctured, beak curved, not as long as the prothorax, 
smooth. Prothorax wider than long, narrowed and rounded on the sides 
near the apex, where it is broadly and feebly constricted ; disc strongly, 
not densely punctured, with an indistinct, narrow, smooth median line. 
Elytra with impunctured striz, interspaces wide, flat, feebly and very 
finely punctulate. Beneath sparsely punctured ; there is a patch of white 
scales on the flanks of the prothorax ; the side pieces of the metasternum, 
and the sides of the ventral segments are also clothed with white scales ;
