with a fine silky brown down, gradually narrowed towards the 

 apex. The under side is blackish-brown, the margins of the 

 individual abdominal segments lighter ; the legs are ferruginous- 

 brown. Nearly constant in size. 



A very distinct species, similar to C. sericeus, and, like it, 

 with transversely wrinkled elytra, but smaller than the smallest 

 individuals of that species, and easily distinguished by the wholly 

 different form of the antenna?, by the gradually narrowed and 

 not truncate elytra, and the stronger more distant transverse 

 wrinkling. The club of the antenna? is as a rule somewhat 

 darker, the last joint somewhat larger than the preceding, cone- 

 shaped, acuminate. 



Kraatz says that it is taken near Berlin in loose sand at the 

 foot of old oak-trees, and that it is frequent in moors.

Fuscous ; head and thorax with fulvous sericeous 

 pubescence ; elytra ferruginous-brown, with the ante- 

 rior half of the sutural margin and the margins of 

 the elytra darker; innexed margins of elytra and 

 margins of under side of thorax clear ferruginous, 

 remainder of under side pitchy-black; legs ferru- 

 ginous. Antenna? with base ferruginous, club and apex dark ; 

 first joint large and long ; second not so long ; third and fourth 

 of nearly the same length ; fifth shorter than fourth ; sixth 

 shorter than seventh ; seventh large and broad ; eighth very 

 small ; three last nearly of the same size. Thorax faintly trans- 

 versely strigose, posterior angles obtuse. Elytra deeply trans- 

 versely strigose. Scutellum elongate. Sutural stria shortened, 

 joining the suture at about one- third from the apex. Elytra 

 truncate at the apex; pubescence on elytra darker than on 

 thorax. 



This species has a great resemblance to C. sericeus, but differs 

 from it in the following particulars. In general outline it is 

 scarcely broader in front than behind, while sericeus is usually 

 markedly so. The thorax begins to round-in towards the head 

 almost immediately from the base forward, while in sericeus it 

 does not begin to turn inwards till about the middle of the
