336 GEORGE D. HITLST. 



gulate ; the costal aud outer sharlings are heavier, the outer space sometimes 

 being well darkened ; the hind wings are slightly wavy margined, not angulate 

 as in D. festa; beneath as D. festa, but ochreous, and with shadings much inten- 

 sified. 



Three females, Colorado. The specimens differ considerably, one 

 havino; the outer mara-in much darker than the others, and one hav- 

 ing the ground color a bluish gray, as in D. festa. I would regard 

 them as varieties of festo, were it not for the marked difference in 

 the shape of the hind wings.
