is rugulose and towards the base and angles subopake), the truncated palpi, and the 

 scarce perceptibly sinuated elytra. Chaudoir places C. semiopacus in his second section 

 (" episterna postica latitudine parum longiora"); but the episterna are very little longer 

 than in any of the moestus group, and I suspect this is a character which varies to some 

 extent in one and the same species.
