148 Proceedings of the 



arched. Elytra of a brown, more or less dark, finely transversely 

 strigose, becoming narrower from the base to the extremity, 

 which is obliquely truncate. Legs brown ; thighs often blackish. 

 Size very variable. 



Distinguished at first sight from all the allied species, except 

 varicornis and validus, by its truncate elytra. From C. varicornis 

 it is distinguished by the apex of the antennae not being light- 

 coloured, and from C. validus by its smaller size and by the dif- 

 ferent proportions of the joints of the antennae. 



Common in Britain, and generally distributed all over Europe.

Long, li lin. 



Closely allied to C. sericeus, and principally distinguished by 

 the form and colour of the antennae, which are shorter and 

 ferruginous both at the base and the apex, and the beetle is usually 

 somewhat darker. The head is broad, finely punctate, shining 

 black with a grey pubescence ; the mouth ferruginous-red. The 

 antennae scarcely reach beyond the half of the thorax, and are 

 thickened on the outer side so as to be distinctly club-shaped. 

 The individual joints are as in the C. sericeus, but form a rounder 

 oblong and thicker club. The first five joints are ferruginous- 

 red, those following brownish ; the eighth shorter but not more 

 slender than the remainder ; the last transverse, short, and very 

 obtuse, much shorter than in the C. sericeus, and reddish-yellow. 

 The thorax is large, black, shining, clothed with a silky pubes- 

 cence, almost square, a little broader than long, of the breadth 

 of the elytra, somewhat narrowed in front, gently rounded on 

 the sides ; the posterior angles pointed, projecting slightly back- 

 wards, the posterior margin rounded. The scutellum is large, 

 triangular, transversely strigose. The elytra are dark brown, 

 finely transversely strigose, a little arched, somewhat rounded on 

 the sides, moderately narrowed towards the extremity, not so 

 strongly truncate at the apex as in C. sericeus, and more rounded, 

 with a fine brownish pubescence. The under side is black ; the 

 legs are brown, the tarsi paler. 



The pale terminal joint of the antennae, combined with the 

 general appearance of C. sericeus, at once indicates this species.
