Length 5 millim. 



Mas. — Narrowly parallel, the head broad, greenish black, 

 impunctate, the frontal tubercles strongly raised, triangular

 portion of the face thickened below the eyes, deeply exca- 

 vated above the clypeus, the cavity furnished with some 

 hairs and a tooth or thorn-like lamina at the U])per portion ;
