The best distinctive characters of this species among its near 

 allies seem to be the strongly defined postbasal wide transverse 

 impression of its elytra, which in some examples is even limited 

 behind by an indication of a raised margin (when looked at from 

 a certain point of view) suggestive of the transverse wheal-like 

 ridge that characterises P. transversalis, ikc, and the well- 

 marked longitudinal depression between the discal and marginal 

 parts of the elytra. In addition to the usual sexual distinctions, 

 I find that in the male the greatest width of the elytra is 

 distinctly nearer the ape.K than in the female, and that the female 

 is more strongly convex than the male. In one example the 

 elytra bear some ill-defined piceous blotches.
