Genus Argynnis 
yellowish, 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.
