feet are small.

The acuminated and costated elytra, with the peculiar form of the anterior tibiw, well distinguish this 
species, especially from C. trabecula. 
The clypeus is not reflexed at its fore margin (fig. 4), which is slightly emarginate. The maxille (fig. 4) 
have the galea moderately long and bidentate, and the mando is short, and notched at its tip. The mentum is 
oblong, rather narrowed across the middle (fig. 4c), rather deeply notched in the middle of its fore margin, the 
angles of which are rounded; the dise is rather slightly longitudinally impressed, forming only a very slight 
angle before the middle. The prosternum is armed before the anterior cox with a deflexed spine, setose in 
front (fig. 4a). The anterior tibiw, in some specimens (fig. 4d), terminate in a broad flat lobe, rounded and 
entire on its outer edge, but in others the outer edge of this lobe has a more or less distinct angular incision 
(figs. 4e and 4/7). I presume that the former are males, and the latter females, although in all the abdomen is 
convex beneath ; in those, however, with the entire tibia, the pygidium is convex, but in the others it is rather 
flattened in the middle, with a very slightly-defined longitudinal carina. The anterior tarsi have the five joints 
marked with an impressed line. The elytra, when seen with a lens, are delicately shagreened, being, except at 
the base and along the raised coste (which are more regularly punctured), entirely and thickly covered with 
minute short lines, either straight or angulated, amongst which a few more distinct punctures are to be seen.

This species is distinguished by its convex head, nearly circular prothorax, short legs, and prominent 
posterior spiracles. The clypeus is dilated at the sides, and rounded in front. The head is convex, and thickly 
but very finely punctured (fig. 6a); the fore margin is not reflexed. The maxille have the galea large and sickle- 
shaped, with two very sharp equal spines; the mando is smaller, the under tooth being smaller than the upper 
(fig. 64). The mentum is obtriangular, being widest and truncated in front, where it is thickened into a trans- 
versely triangular mass, the apex of which is concave (fig. 6c, the mentum seen from beneath; 6d, seen from 
within, shewing the palpi concealed from above by the dilated sides of the mentum; 6e, the mentum seen
