 joint in the male is abont luilf as long as the eleventh, in the

This sj)ccics has some resemblance to C. o'nereum, but can 

 be easily distingui«;hcd from any of the allied species by the 

 distinct twelfth joint to its antenna;

Head with rather strong mandibles ; with the cheeks 

 prominent and somewhat bluntly pointed, widely separated 

 below, with a distinct transverse groove on the underside of 

 the head between them. Eyes railier small, the lower lobes 

 transverse, somewhat pointed in front. Prothorax subquad- 

 rate, constricted at the base and apex, slightly rugose above, 

 somewhat uneven at the sides, covered with a thick greyish 

 or fulvous pubescence. Elytra with a rather dense ashy-grey 

 decumbent pubescence ; the apices broadly truncate, each 

 vrith two spines, of wbich the outer is stronger than the 

 sutural one. Body underneath and legs with a fulvous-grey 

 pubescence. Tibiaj each armed with a spine at its outer distal 

 termination ; intermediate femora unispinose at the apex ; apex 

 of the posterior ieniora spinose behind, dentate or sharply 

 angulate in front. Antenna? ((^) a little longer than the 

 body, thickly fringed with tawny hairs underneath. 



The name hohsericeum seems particularly inappropriate to 

 the present species. 1 can see nothing in the three specimens 

 before me that could have suggested silkiness ; their pubes- 

 cence, in its present state at least, is entirely devoid of gloss.
