 Long., 5 1. ; lat., 3 1. 



A species of broader and less parallel form than is usual 

 in this group, resembling in outline the species that I take 

 to be P. j)dtnUis, Er. The granules on the elytra are con- 

 fined to the subapical portion and are extremely small and 

 inconspicuous.

 strigato. Long., 8 1. ; lat., 3f 1. 



Allied to P. granulatus, Germ., but very distinct from 

 it by the lateral margins of its elytra much less widely ex- 

 planate : differs from gronvlaius also by, inter alia, its larger 

 size, more elongate build, front of prothorax more narrowly 

 emarginate, and with more rounded angles, elytra with more 

 numerous granules, ventral segments almost without longi- 

 tudinal wrinkles, etc.
