Two specimens exaniined, both 9, I think, belong to a species 

 singularly like P. chalco'pUroides Cart., in form, size, and colour. 

 It may be readily distinguished from it, however, by the follow- 

 ing differences, vater alia. Anterior angles of prothorax more 

 acute (though slightly blunted at tips), and more strongly pro- 

 duced; disc of prothorax and epipleura? of elytra more strongly 

 punctured: the elytral sculpture entirely difierent, as follows : — 



P. cJialcopteroides. — With ten rows of small punctures, in- 

 tervals wide and flat. 



P. similis. —About fourteen rows of large punctures, including 

 a sublateral irregular system: intervals narrow and convex, with 

 one wider subcostate interval.
