Allied to both C. Tarandus, Thunb., and C. Mniszechii, Thoms. 
(comparing specimens of similar development); from the former 
it is at once distinguished by the pale chestnut and non-zneous 
colour of the elytra, which are somewhat broader and shorter, 
and, further, by the totally different armature of the mandibles ; 
from the latter by its larger head, and shorter and less convex 
elytra; and, finally, from both by being clothed with griseous 
scales, in which it assimilates with C. Dehaanii, Westw. I must, 
however, remark that the sparse distribution of the scales in the 
specimen described is probably attributable to attrition. There 
is an insect in the British Museum from the Philippine Islands 
to be referred to this species.

This insect belongs to the second section of the genus, which 
may be characterized as “ griseo-squamose;” it approximates 
somewhat in general appearance to C. Dehaanii, Westwood, from 
which, however, the peculiar sculpture of the elytra, as well as 
the armature of the mandibles, readily distinguish it.
