Typ. in coll. mea. 



Avery short robust species; black, clothed with a dense covering of 

 closely lying white hairs, giving the insect a gray appearance. Head 

 large, red (a frontal spot, the mouth parts and antennse are black), 

 feebly punctulate, clothed with short white hairs (very small and sparse 

 on the vertex); eyes long, narrow and oblique; antennce filiform, first 

 joint long, second joint constricted before the base, third joint twice as 

 long as second and much longer than fourth. Thorax quadrate, wider 

 than long, with a very faint median longitudinal groove, closely and 

 finely punctured. Scutellum small, triangular. Elytra also closely and 

 finely punctured, with a white dorsal vitta (formed by a thicker 

 arrangement of the hairs of the elytron) reaching from the base to 

 almost the apex of the elytron; a white margin to the elytron formed 

 in the same way. The legs and under surface of the body are closely 

 covered with fine white hairs. There is a concave sericious spot on 

 the inner surface of the front femora and tibise. The hind legs are very 

 long.
