This species is readily distinguishable, in the aggregate 

 having the 6th joint of the antennae strongly dilated, by its 

 very short antennae, depressed form, flat elytral interstices, 

 and very fine elytral granules, — the latter almost obsolete in 

 the scutellar region. Its prothorax resembles that of P. bul- 

 la t us, Pasc.

 Allied to /'. hi/Ih(fifs, Pasc, from which it differs by 

 inte?' alia its smaller size, its prothorax less transverse more 

 narrowed and more deeply emarginate in front and with much 

 better defined front angles, the alternate interstices of its 

 elytra more distinctly convex, and the 6th joint of its antennae 

 scarcely transverse. In some examples the elytra have a 

 slightly bronzy tone.
