terior part of the metasternum is large, sparsely punctured, with a median 
impressed line, each side of which is a shallow round impression. Legs 
slender, rather long, middle coxee separated by the metas‘ernal process ; 
middle legs received in transverse excavations, which extend on the epi- 
pleure ; hind legs received in excavations which occupy the whole of the 
length of the 1st ventral segment, and extend to, but. not upon, the edge 
of the elytra; tarsi broad, Ist joint not elongate, 5th not narrower nor 
longer than the 4th; claws small, divaricate, appendiculate, ventral seg- 
ments 5, as usual; Ist short, occupied by the excavations for the hind legs ; 
2d, 3d and 4th equal, each about twice as long as the Ist; 5th nearly as 
long as the two preceding, broadly rounded ; the sutures are equally plain 
and straight, Elytra striate. 
This genus is allied to Dorcatoma and Cenocara, but differs 
from both by the elytra being striate, by the 2d joint of the 
antennz being larger, aud by the form of the metasternal 
process which is much narrowed at base in Dorcatoma, and 
very short in Cenocara. Having seen but one specimen, L 
am unwilling to risk it by an attempt to expose the pros- 
ternum, especially as the genus is very well characterized 
without reference to that part. 
99. Byrrhodes setosus, n. sp.—Robust, oval, convex, obliquely nar- 
rowed in front, blackish-brown (somewhat shining where the hair is re- 
moved), densely clothed with coarse white curled hairs, very finely and 
densely punctulate. Head with a transverse frontal impressed line near 
the margin ; sides obliquely margined. Prothorax short, of the same form 
as in Cenocara, outline when viewed from above oblique. Scutellum flat, 
rounded. Elytra with well impressed striz, the two outer ones deeper be- 
hind the middle ; interspaces wide, flat, the outer ones slightly convex be- 
hind ; lateral edge finely margined from base to tip. Beneath nearly 
smooth, very sparsely punctulate, Sterna glabrous (by abrasion ?), abdo- 
men hairy. Length 3.5 mm.; .14 inch. 
Capron; one specimen. On superficial view, this insect 
might be readily mistaken for a small species of Byrrhus. 
100. Elaphidium tectum, n. sp.—Elongate, slender, brown, clothed 
with short fine rather dense dirt colored pubescence, scarcely mottled on 
the elytra. Antenne (,j') as long as the body, joints 3-10 each with a 
spine at the inner apical margin; the spine of the 3d is about one-fourth 
as long as the 4th joint, the others diminish gradually in Jength ; the outer 
apical angle of the joints 5-7 is also armed with a small spine. Prothorax 
a little wider than long, moderately rounded on the sides, densely punc- 
tured, with a smooth dorsal line more distinct behind the middle, and a 
discoidal round callus each side in front of the middle; on the deflexed 
sides near the base are seen a few large round punctures or fovee. Elytra
