Black, nitid, protliorax and elytra with violet margin. Head 
large, sub-quadrate (5x6), narrowed behind the eyes ; two supra- 
orbital punctures on each side ; frontal sulci converging slightly 
towai'ds the front, where they turn shai’ply out towards the 
anterior angles of the head ; occiput with a distinct transverse 
impression which connects the sulci behind. Prothorax large, 
transverse (6 x 8), rounded behind, slightly rounded on the sides ; 
the anterior angles hardly at all advanced, the margins narrow ; 
the median line distinct, and crossed throughout its length by 
minute transverse striolae ; three marginal punctures on each 
side. Elytra large, rather convex (13 x 8|), slightly wider than 
the thorax, truncate at tlie base, rather parallel on the sides ; the 
surface appears quite smooth to the eye, but with a lens very 
faint longitudinal striae may be discerned ; the lateral margins 
narrow, and a little thickened at the humeral angles ; two punc- 
tures near the shoulders, and two towards the apex. Anterior 
tibiae bidentate. 
This species is very closely allied to C. interruptum, Mad./ it is, 
however, a rather larger insect, more brightly coloured, and has 
the stx’iae of the elytra less distinct.
