Krauss, evidently relying upon a manuscript name of Brunner's, 

 without further reference to the literature, erected the evident 

 synonym, truncata. This synonymy was indicated by Kirby in 

 1904.'^^ 



The species has been generally correctly recorded in the litera- 

 ture; unfortunately, however, North American material of P. 

 Juliginosa has been regularly assigned to the present species by 

 Caudell, Rehn and Hebard, two records by the latter authors, 

 however, being correct. 



The species is easily determined from the male genital features; 

 agreeing much more closely, however, with Juliginosa and P. aus- 

 tralasiae than with the distinctive P. americana. With the latter 

 species, however, females might easily be confused, the features 

 separating these species in that sex being much less marked, as 

 discussed under americana, and the coloration being of the same 

 general character and occasionally very similar. 



The insect in size averages smaller than americana, with tegmina 

 and wings not as elongate, particularly in the male sex; the paired
