Remarka,ble for the expanded margins of its pronotum 

 being narrower and less clearly distinguishable from tbe disc 

 than is usual among its allies. The expanded margin of its 

 elytra also is very narrow, much narrower than in, e.g., P. 

 hvlhitun, Pasc. The shining granules form complete rows on 

 the alternate interstices of the elytra, but they are extremely 

 minute on the front part and even more so near the suture 

 than near the lateral margins.
