yellow at the apex of the primaries contrasts much more strongly. 
The spots on the under side in the female sex are frequently well 
silvered, though in many specimens they are colored exactly as 
in the male sex. Expanse of wing, 3, 2.17 inches; $, 2.50 
inches. 
Early Stages. — The early stages of this species have not as 
yet been ascertained. 
This beautiful butterfly, which is somewhat inclined to varia¬ 
tion, is found in northern California, being quite common about 
Mount Shasta. It is also found in Oregon and Nevada. One 
of the varietal forms was named Argynnis purpurescens by the 
late Henry Edwards, because of the decided purplish tint which 
prevails on the under side of the secondaries, extending over the 
entire surface of the hind wings and covering likewise the apex 
of the fore wings. This purplish-brown is very marked in speci¬ 
mens collected about the town of Soda Springs, in northern 
California.

Butterfly. — This species is very closely allied to the preced¬ 
ing in some respects; the upper surface, however, of the wings 
in both sexes is brighter than in serene, and the dark markings 
stand forth more clearly upon the lighter ground-color. The 
wings are not shaded with fuscous toward the base as much as 
in A. serene. While the markings on the upper side are almost 
identical with those of Dr. Boisduval’s species, they are much 
brighter and clearer, giving the insects quite a different aspect. 
On the under side the wings are colored as in %erene, the prima¬ 
ries in the male being ferruginous, laved with a little red toward 
the base, marked with purplish-gray toward the apex, the light 
spots near the end of the cell on this wing being pale buff. The 
hind wings are very uniformly purplish-gray, mottled with dark 
brown, the spots very little, if at all, silvered in the maie. In the 
female the fore wings are bright red at the base, and the hind 
wings are colored as in the male; but all the spots in both the 
fore wings and hind wings are broadly and brightly silvered. 
Early Stages. — The early stages have not been ascertained, 
and there remains something here for young entomologists to 
accomplish. 
This species is quite common in the same localities as the last
