This species is easily recognized by the black thorax, having the 

 anterior two thirds of the reflexed margin deep yeUow, the line of 

 demarcation between the yellow and black clearly defined. The 

 black at the apex of the elytra extends for rather more than a 

 quarter of their length. The region of the scutellum is frequently 

 dusky ; but it is not so in the type specimen, which is a male. 



c? . Elytra nearly as broad as long, inflated ; the margins not 

 visible from above, except posteriorly.
