ARGYNNIS IV. 
beneath buff, with gray and fulvous hairs, abdomen buff; legs fulvous; palpi 
fulvous, with buff hairs in front; antennae fuscous above, fulvous below ; club 
black, fulvous at tip. 
Female. — Expands from 2.3 to 2.7 inches. 
Upper side paler; the marginal lines and crescents confluent, forming a broad 
black band, the enclosed fulvous spots paler than the ground color; the other 
markings as in the male. 
Under side of primaries deep red, ochraceous apically; the silver spots distinct, 
three on the ferruginous patch, and five or six along the margin; secondaries as 
in the male, but rather more mottled with greenish - ochraceous; spots larger, 
well silvered. 
This fine species was first made known by Dr. Bremner, of H. M. Ship 
Zealous , who obtained a few individuals on San Juan Island, in 1871, and pre¬ 
sented them to Mr. Henry Edwards. In 1873, Mr. Edwards himself visited Van¬ 
couver’s Island, and writes as follows : “ Bremnerii is remarkably common in the 
vicinity of Victoria. I observed it in great numbers at Esquimalt, and on a 
patch of clover, which was in full flower at the time of my arrival, I captured 
over sixty specimens. The great majority of these were males, and from my 
own experience, and that of other observers, with the larger Argynnides, I be¬ 
lieve that the females of Bremnerii would not appear in any number before the 
end of August, while the male is abundant in June. It seems to be the only 
large species of Argynnis inhabiting this Island. Its flight is somewhat slow and 
heavy, and being a fearless insect, its capture is a matter of no difficulty.” In 
August, 1873, also, Mr. G. R. Crotch was collecting in British Columbia, and 
found Bremnerii abundant at Fraser’s River and at Lake Labache. With it was 
flying A. Aphrodite, scarcely differing from its type of the Eastern States. This 
alone of the large Atlantic species of Argynnis is found on the Pacific coast, and 
so far as now known, is confined to British Columbia. Both Atlantis and Aph¬ 
rodite belong to the Coloradan fauna, and the males of the latter species have 
there undergone some modification, having assumed somewhat of the intense 
coloration of the female, while the fore-wings are more produced and more 
arched than in the Eastern type.
