 the apex ; abdomen very broadly concave in the centre ;

 yellowish hair; fore tibiae slightly sinuous on the outer 

 side before the apex. 



The female is rather larger than the male, much more 

 closely and coarsely punctured, has the sutural angles of 

 the elytra less produced, the abdomen convex and with the 

 base of the apical segment coarsely strigose, the legs 

 stouter, the fore tibiae broader, rugosely punctured, and 

 with a rather strong sub-apical tooth, the hind tibiae 

 also having a very distinct sub-median spur and the cephalic 

 horns are rather stouter.

 described pair is in the collection of the Leyden Museum. 



The deeply notched frontal plate will sufiBce to distinguish 

 this species from C. dives Westw., to which it is very 

 closely allied.
