A dark species, having the front parts black with more or less 

 distinct coppery reflections, especially at the sides ; scutellum 



metallic green ; elytra somewhat 

 widened behind, dull velvety 

 black with two testaceous spots 

 on the disc of each, one at middle 

 and one behind, and with the 

 surface irregularly sprinkled with 

 small green or obscurely aeneous 

 ocelloid spots, a character that 

 will at once distinguish the 

 species ; there is also a more or 

 less obscure coppery patch at the 

 shoulders, and the sides are also 

 very narrowly and obscurely 

 metallic at the extreme margins ; 

 labrum large, raised in the middle, 

 metallic ; in the sculpture of the 

 head the species is allied to 

 C. rugosiceps, the space between 

 the moderately prominent eyes
