ARGYNNIS XI. 
Under side as in male except that apex and hind margin of primaries and 
whole of secondaries are of a deeper olivaceous, a paler shade of same color tinting 
those parts that in the male are huff ; the silver spots large, the outer row triangu- 
lar, slightly edged by black above ; the spots little if at all edged by black. 
Larva unknown. 
From specimens taken by Mr. James Ridings in the mountains near Empire 
City, Colorado, in August 1864. 
This species had been known in collections for several years prior to Mr. Ri- 
dings’ expedition, from the Collecting of Messrs Wood, Drexler, and others, and had 
been erroneously taken for Aglaia, an European species to which it bears some re- 
semblance. As Dr. Behr has remarked “ nearly all the Californian Argynnides 
(which includes the Rocky Mts. and Eastern species as well) belong to the type of 
Aglaia , which is altogether more developed and more numerously represented on 
this continent than in the old world, where the type of PajpMa takes its place.”
