is, however, less convex, and the thorax is broader in front. 
Black, with dark greyish pubescence. Rostrum clothed with 
whitish pubescence above; neck with three narrow white 
longitudinal lines, with a black spot behind the eyes. Thorax 
very broad and depressed, with three small tubercles on the 
disk, and with a strong triangular tooth on each side towards 
the front margin, as in 7. frenatus ; blackish, with fine whitish 
lines, those near the posterior margin forming an Ml. Elytra 
blackish, with some large tubercles placed as in 7. frenatus, 
but more distinct ; the whole surface covered with small whitish 
marks, not forming any bands as in 7. frenatus. Legs black, a 
band on the femora, two rings on the tibie, the basal joint of 
the tarsi, and a ring on the claw-joint whitish. Abdomen in 
the male with a black velvety spot in the middle of the second,

Forehead deeply canaliculate; eyes separated above by a 
very narrow space. Antenne with the third joint elongate, 
cylindrical; the fourth joint with a small obtuse tooth at the 
apex; the fifth to tenth joints becoming slightly shorter and 
broader, the internal apical angle of each jomt produced into 
a tooth, more so as the joints approach the apex. Thorax 
convex, twice as broad as long, thickly and strongly punctured, 
sides with a short acute tooth in the middle—in these and 
other particulars agreeing with the thorax of C. flabellicornis. 
Elytra a little broader than the thorax, and five times as long, 
with four nearly obsolete abbreviated coste ; the surface some- 
what sparingly and not strongly punctured.

This species is at once separated from the C. flabellicornis 
by the sparse punctation of the elytra and by its much 
larger size,
