 rax shorter and more transverse, at base nearly twice as wide as long, 

 the ante-scutellar impression unusually deep and very distinct; elytra

8 — More elongate, fusiform and less convex than in the preceding forms, 

 the maculation orange-red; head (9) as in inconstans, or (c?), with

 the pale area deeply, angularly biemarginate posteriorly; prothorax 

 nearly to quite twice as wide as long, almost as in inconstans; elytra 

 gradually becoming oblique posteriorly but with the sides feebly arcu- 

 ate to the truncature, striate nearly as in inconstans, but with the punc- 

 tures of the intervals less coarse, the second interval from the side mar- 

 gins more prominently convex; abdomen sulcate as usual at base, not 

 very coarsely but strongly, moderately closely punctate, the spots of
