This species is nearly allied to the P. fumipennis of Guerin ; 

 but the specimens which agree with the description of that au- 

 thor have a distinctly enclosed rugose space at the base of the 

 metathorax ; the abdomen is not so closely punctured, and the 

 scutellum and post-scutellum are black in both sexes.
