Male: Length — 13 mm. Form subcylindrical, the side margins 
nearly parallel from humeri to level of apex of elytral suture 
(Fig. 2A). Color piceous black, heavily marked above with whitish- 
yellow ; beneath, the lateral portions of the prosternum and abdominal 
sternites, the mesepisterna, and legs, reddish-yellow. Head entirely 
pale, pronotum with anterior half pale, posterior half dark, the dark 
area strongly bilobed on disc. Each elytron has the familiar pattern 
of five pale spots (2.2.1 ) on piceous black, so commonly found among
