This species is most easily distinguished by the coarse 
close puncturation of the vertex. Otherwise it is very near 
hirsutus, Sm., but in that species the sternites are finely 
and very closely punctured, in versatilis coarsely and more 
sparsely punctured.

3. Clypeus broadly subtruncate at the apex; vertex 
rather sparsely and shallowly punctured ; eyes separated on 
the vertex by a distance scarcely exceeding the length of 
the second joint of the flagellum ; galea shorter than the 
scape. Basal joint of the fore tarsus with five spines; spur 
of hind tibia a little shorter than the basal joint of the hind 
tarsus. Second sternite finely and closely punctured ; 
seventh tergite broadly rounded at the apex; eighth sternite
