where it is abbreviated; 8d stria wanting. Beneath finely sparsely 
punctured. Antenne and tarsi yellow-brown. Length 2mm.; .08 inch. 
North Carolina; Dr. Zimmermann, one specimen. This 
species resembles Dorcatoma in the sculpture, but the form is 
more robust, and the eyes emarginate to near the middle. 
98. Caenocara californica, n. sp.—Broadly ovate, convex, black, 
shining, with fine sparse sub-erect hairs. Head and prothorax rather 
densely punctulate. Elytra less densely punctulate, with three stri? near 
the sides; 1st and 2d entire, 3d beginning at the base and extending one- 
third the length ; there is no marginal stria. Beneath finely punctured 
(antenne not seen). Eyes almost divided. Length 1.5 mm.; .06 inch. 
California; one specimen received by Dr. Horn. Very 
similar to the small form of C. oculata, but differing by the 
more densely punctured prothorax, and more finely punc- 
tured under surface.

Broadly ovate ; eyes nearly divided by a deep narrow emargination ; 
1st and 2d striz of elytra entire ; 3d extending one-third the length.2. 
Less broadly ovate, eyes emarginate only to the middle; 2d stria of 
elytra abbreviated behind, 3d obsolete 5. intermedia, n. sp.

Lateral lobe of elytra with a distinct marginal stria. Head and protho-

BYRRHODES, nov. gen. (ANOBIINI.) 
Body rounded, slightly oval, convex, pubescent with coarse hairs. Head 
inflexed, broad, mandibles resting against the metasternum in repose ; un- 
der surface . Antenne 10-jointed ; 1st joint large, auriculate, 2d nodose, 
rather large, attenuated at base, 9d slender, 4th and "7th subtransverse, 
gradually slightly wider (4th appears to be indistinctly impressed trans- 
versely); 8th triangular, as long as the whole stem, from the 2d to the 7th ; 
about twice as wide as long, remaining joints broken. Palpi not seen. 
Eyes not convex, not emarginate, partly covered behind by the prothorax. 
Prosternum not seen, front cox& deeply sunk in the cavity, not seen. 
Mesosternum concealed by the metasternum, which is produced in front 
into a broad square process, the anterior margin of which is slightly 
rounded, and the front angles are acutely prominent laterally. The pos-

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 coxe separated by the metasternal 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, 1st joint not elongate, 5th not narrower nor 
longer than the 4th; claws small, divaricate, appendiculate, ventral seg- 
ments 5, as usual ; 1stshort, oceupied 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 
antenne being larger, and 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, I 
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 stri&, 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 superfieial 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 ($) as long as the body, joints 3-10 each with a 
spineat the inner apical margin; the spine of the 3d is about one-fourth 
as long as the 4th joint, the others diminish gradually in length ; the outer 
apical angle of the joints 5-7 is also armed with a small spine. Prothorax 
& 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 fovex. Elytra
