Resembles humeralis in form. Black ; elytra from base to middle orange 

 yellow. Elytra much less coarsely and less deeply punctate than humeralis; 

 those of females emarginate and somewhat toothed at apex. Length 12- 

 19 mm.

Small, slender forms, having the front of head short, not ab- 

 ruptly defined each side; antennae a little shorter than body, the 

 latter pilose ; scutelium small ; thorax margined at apex. One of the 

 three recognized species occurs in the State.

 vertical; antennae as long as body in female, somewhat longer in 

 male, tapering, punctured and pubescent, second joint small, third 

 longer than fourth, 3-7 armed with short apical spine on the inner 

 side; scutelium rounded behind; elytra truncate at tip and armed 

 with two apical spines ; tibia- strongly carinated and the first joint 

 of tarsi as long as the two following united.
