Male : Black, sub-opaque on the head and prothorax, elytra 

 shining ; clypeus very widely emarginate at tip, the emargination 

 being triangular, and very slightly sinuate on each side, gense pro- 

 jecting slightly beyond the line of the clypeus, the whole head is 

 very deeply and somewhat roughly punctured, and in the centre there 

 is a short, strongly hamate horn, broad and thick at base but very 

 sharp at tip and not higher than the apical truncate part of the walls 

 of the prothoracic median excavation which is deep and slopes from 

 a very short distance from the base to the apical margin ; the two 

 walls of this excavation are horizontal except for a slight sinuation 

 near the anterior part, and are abruptly truncate in front, while on 

 each side of them, close to the apical margin, there is a deep, curved 

 emargination, the dorsal part is covered with very closely set fovese, 

 and so is the median excavation except near the basal part, but 

 round the supra-marginal lateral fossa there is a smooth area ; 

 elytra deeply striate, striae not distinctly punctate, intervals slightly 

 convex and punctulate ; anterior tibiae curved outwardly. 



Female unknown. 



Intermediate in shape and size between C. fidius and C. hootes, 

 but easily distinguished from the former by the very widely emargi- 

 nate clypeus and the not deeply punctured intervals of the elytra ; 

 from C. bootes it differs in the shape of the cephalic horn which is 

 short, broad and thick at base, and strongly curved and sharp at 

 tip, as well as by the non-opaque elytra. 



I have not been able to ascertain by dissection the sex of the type 

 of Boheman's example, but the fact of the elytra being distinctly 

 shining in C. cxcavatus, and opaque in C. bootes, would seem to 

 preclude the possibility of the former being the female of the latter, 

 which is, however, not yet known.
