Collected by the Jate M. Mouhot, and allied to C. Buddha, 
Hope (Trans. Linn. Soc. xix. 107), the type specimen of which 
is in my own collection, but differs in the form and armature 
of the mandibles, in the head being wider and much less emargi- 
nate in front, and in the narrow and more attenuated form of the 
elytra.

This species is allied both to C. Senegalensis, Klug, and C. 
quadridens, Hope, from which, however, its rich chestnut colour, 
similar to that of C. Savagei, Hope, at once distinguishes it.
