66 PROCEEDINGS OF THE NATIONAL MUSEUM vol.91 



In addition to the specimens listed above, I have before me one 

 other from Logan Canyon, Utah (August 16, 1939, G. F. Knowlton 

 No. 34) , which appears to belong here. This specimen, however, lacks 

 the usual median dorsal black line of the abdomen, and the hind wing 

 is more cerise, with the dark spots greatly reduced.

 to separate the two in borderline cases.
