One specimen. (Belfrage.) 



In the collection of the American Entomological Society there is 

 another species belonging to this genus, from West Virginia, which 

 I have named P. virginiensis. It is a % , having the eyes larger than

 tennae entirely black; the scutellum broadly concave; anterior legs 

 honey-yellow, with coxae beneath, tibiae, and tarsi except tips, white ;
