abdomen rather more pronounced than in male, the first three slightly produced 

 backward at the sides. 



Minot, North Dakota, Aug. 22, 1915. One of each sex on Grindelia 

 squarrosa. Allotype No. 9293; male No. 9294. The female runs in Cockerell's 

 table (1896) to zonalis Cress, or rectangulata Ckll. It resembles the latter in 

 face markings. Mr. E. T. Cresson, Jr., has kindly compared these with the 

 type of P. mnrtini and considers them identical. He notes: "yellow of cheeks 

 to '/2 eye and black of occiput extends nearly to lower orbit level; mid-tibiae 

 not darkened, post-tibiae darkened above, all femora immaculate; nervures 

 pale and all pale parts more whitish than yellow." He also sends a sketch of 

 the pleural markings, which shows a rather greater and more irregular extension 

 of yellow on the fore part of the mesopleurse.
