are densely covered with hair-bearing punctures which 
become smaller near the scutellum and apex; the apex of 
each elytron is faintly emarginate. 
Undersurface and legs shining; prosternum, mesosternum 
and abdomen nearly impunctate, metasternum and femora 
very distinctly punctured, tibiae more finely and densely.
