Qenus Argynnis 



vc'ilowlsh, and the marginal lines are confluent on the upper half 

 of these wings. The wings on the under side in this sex are as 

 in the male, but the ground-color on the inner half of the wings 

 is darker, and the spots are more brilliantly silvered. Expanse, 

 2.30-2.50 inches. 



Early Stages. — Unknown. 



This pretty species is found with A. electa and A. hesperis in 

 Colorado. It was originally described from specimens taken at 

 Manitou and Ouray, and named by Edwards in honor of a de- 

 ceased daughter of Professor Owen of the University of Wis- 

 consin. 



(15) Argynnis electa, Edwards, Plate X, Fig. 8, $ (Electa). 

 Butterfly. — The male is dull reddish-fulvous on the upper 



side. The black markings are narrow. The base of both wings 

 is slightly obscured. On the under side the fore wings are pale 

 cinnamon-red, with the tip dark cinnamon-red. The hind wings are 

 broadly dark cinnamon-red, mottled on the disk with a little buff. 

 The submarginal band is buff, quite narrow, and often invaded 

 by the ground-color of the inner area. The silvery spots are 

 usually very well marked and distinct, though in a few instances 

 the silvery color is somewhat obscured. The female has the 

 black markings a little heavier than in the male; otherwise there 

 is but little difference between the sexes. Expanse, 2.00-2.25 

 inches. 



Caterpillar, etc. — The early stages are unknown. 



This species has been confounded with A. atlantis, from 

 which it is wholly distinct, being much smaller in size, the fore 

 wings relatively broader, and the markings not so dark on the 

 upper surface. It is found in Colorado and Montana, among the 

 mountains.

Butterfly. — The male has the upper side of the fore wings pale 

 reddish-fulvous. In the median band of both wings the spots do 

 not flow together, but are separate and moderately heavy. The 

 underside of the fore wings is pale fulvous, buff at the tip; spots 

 silvered. The hind wings on the under side are light rusty-red, 

 but little mottled with buff on the disk; the submarginal band is 

 narrow, buff, and sometimes almost wholly obscured by the darker 

 ground-color. The spots, which are small, are well silvered.
