WILLIAM (I. DIETZ, M. I). 
spaces densely j)unctnlate. Prosternum very short in front of coxa?. 
Mesosternnin moderately wide, but short, between the coxm and al- 
most perpendicular in front. Metasternum short, as long as the first 
ventral segments at middle. Abdomen broadly ovate; first and 
second segments rather short, segments 3-5 about equal, and each but 
little shorter than either of the former segments ; pygidium not 
visible, under snrhice sparsely pubescent. Legs rather short and 
stout. Femora clavate, all toothed. Tibiie short, slightly compressed, 
subparallel, feebly bisinuate internally ; articular surface scarcely 
oblique. Anterior and middle tibiie feebly unguiculate, posterior 
mncronate at apex. Tarsi stout, first joint but little longer than the 
second, and each with several suberect, stout, clavate bristles, arising 
from the upper surface ; third joint deeply bilobed. Claws armed 
with a large, obtuse tooth. 
Related to the preceding genus by the form of the abdomen, the 
covered pygidium and the irregular, tuberculate surface, but readily 
distinguished from it by the mncronate posterior tibiae and from all 
others by the short, oblique scrobes. 
A single species. 
1. C. insolent u. sp. Plate v. figs. 4-4a. — Eufo-piceous, densely clothed 
with fine yellowish pubescence. Prothorax wnth a prominent, semi-circular ele- 
vation. in front of which there is a hroad, transverse impression ; broadly im- 
ju'essed each side of base. The elevated points are clothed with pale, the de- 
pressions with fulvous i)ubescence. Elytra broadly oval, a trapezoidal space in 
front and extending about one-third the length of the elytra, rufous and clothed 
with pale ochreous pubescence. The rest of the surface is dark piceous and 
clothed with yellowish gray pubescence; an oblong tuberosity on the third, fifth 
and seventh interspaces about their middle and arranged in a somewhat oblique 
line. A small hut acute tubercle on the third interspace posteriorly. Posterior 
to the basal margin is a broad, transverse elevation and between this and the 
oblique row of tubercles each side, a broad impression ; another tubercle is situ- 
ated oil the fifth and seventh interspaces anteriorly. The under surface is more 
thinly pubescent. Long. 2.25 — 2.5 mm. ; .09 — .10 inch. 
Hah. — Ctiliforuia ; exact locality not given. Collections of Dr. 
Horn and E. A. Schwarz. The tubercles vary in development.

As here restricted, the genus presents the following characters: 
Beak vtiriable, genei’ally long and slender, more rarely shorter and 
stouter. Scrobes long, directed against the eye. Antennte variable; 
scape reaching the eye, or very nearly so; funicle 6- or 7-jointed. 
Club ovoidal, annulate in some, more loosely articulate in others.
