LeConte. | 414. [Feb. 1, 
coarsely not densely punctured, punctures smaller towards the tips, which 
are bispinous, the outer spine much longer than the sutural. Thighs of 
the hind legs with a short spine on the inner side. Length 15.6 mm.; 
.63 inch. 
Cedar Keys; two 3. This species is related to H. mucro- 
natum and incertum, but the antennee are not longer than the 
body, and the pubescence is more uniform ; the punctures of 
the elytra are also more distant. It seems to resemble H. la- 
natum Chevr. (Am. Ent. Soc. Fr. 1862, 260) from Cuba, and 
I should consider it as the other sex of the same species, ex- 
cept that the outer angle of the 3d and 4th joints is not 
armed with a spine.

Enterprise. The specimens agree perfectly with the de- 
scription given of this Cuban species, which was not previ- 
ously known in our fauna. 
102. Leptostylus arcuatus, n. sp.—Fuscous, densely clothed 
with gray hair. Elytra flattened on the disc, hind third of surface smoky - 
brown, limited in front by a curved blackish line, concave forwards ; this 
line is angulated about the middle of the width, then again concave for- 
wards, and joins a lateral narrow black line, which is dilated behind the 
humerus ; asperities black, sparse, small, arranged in distant rows ; tips 
strongly and obliquely truncate, outer angle prominent ; punctures coarse, 
rather densely placed. Prothorax without discoidal inequalities, nearly 
twice as wide as long, sides oblique from apex to beyond the middle, where 
they are distinctly angulated, then narrowed to the base; there is a small 
black spot extending from the base to the lateral angle. Beneath brown, 
finely pubescent, not mottled, legs scarcely mottled ; antenne a little longer 
than the body, punctured and annulated. Length 8 mm.; .382 inch. 
Tampa; one specimen. A very distinct species. The Ist 
. joint of the hind tarsi is as long as the two following, and 
the lateral angle of the prothorax is obtuse, not rounded, but 
also not prominent, and is distinctly nearer the base than the 
apex, while in all the others in our fauna it is at the middle 
of the side, and obtusely rounded. It might be properly 
referred to Sternidius, but in that genus the lateral angle of 
the prothorax is more prominent. Until another revision 
of this division of Cerainbycide is made, I preter to place this 
species in Leptostylus, rather than to establish it as a separate 
genus.
