Pubescence whitish ashy grey, tinged with tawny browu, this colour forming 

 faint s])0ts chiefly on the vertex, prothora.x, and sculelliun. Antennae rather short 

 and thin, extending only a little beyond the tiji of tlie elytra in the mule, and 

 reaching somewhat beyond the middle of the elytra in the female. The tubercle at 

 the basal margin of the elytra is rather high ; the second, placed behind the first, 

 forms a short crest, densely covered with rather long and entirely black hairs. Of 

 the two ])Ostiuediau tubercles the outer one is the smallest. Besides these tubercles 

 there are three faintly raised lines on each elytron, becoming somewhat more con- 

 spicuous here and there where their pubescence is a little erect. The punctuation 

 very coarse and confluent beliind tlii' shoulder angles, with the interstices partly 

 forming granules. Under suH'acc uniformly grey ; legs with some small dark spots ; 

 tarsi beneath tawny brown : last ubdoniinal segment of the male witli a dense 

 grey pile.

Stouter than C. plumosus Serv. Pubescence gre)-, mottled with brown ; disc 

 I if prothonix and scutellum conspicuously greyish white. Third auteuual joint 

 longer than the scajie. Sides of the prothorax with a second large toothlike tubercle 

 in front of the usual lateral tooth ; the tubercles of tlie disc less transverse and 

 more raised than in (J. pluinosas. Tubercles and pnuctuatiou of the elytra as iu 

 C. plumosu-ti ; but the tip of each elytron is truncate, with scarcely a trace of 

 emargination. Outer edges of the intermediate tibiae clothed with a black pile.

In one specimen the second basal tuft of l)lack hairs is almost absent, and each 

 elytron has three feeble but distinct raised lines formed by a somewhat erect 

 pubescence.
