Black, the vertex of the head, and the pronotum (more or less) 

 often piceous or brown; face and occiput yellow or ferruginous; 

 basal two, and sometimes the third joint of the antennae more 

 or less, pale; legs pale yellowish brown or testaceous, in parts 

 often dark brown, variable in colour. 



Head rather long, very much longer than half its width, and 

 owing to a very minute puncturation or surface sculpture little,

 twice as long as the second. Pronotum with close and very fine

 almost on. Abdomen smooth, shining, glabrous, no longish hairs 

 basally. Length 3-3.5 mm.
