Genus CEneis 
(5) CEneis ivallda, Mead, Plate XXVII, Fig. 9, 6 (Mead’s 
Arctic). 
Butterfly.— This species is easily distinguished from all others 
by the peculiar pale ashen-brown of the upper side of the wings. 
It is not a common species, and is apparently restricted to the 
mountains of Nevada, principally about Lake Tahoe, though it 
probably occurs elsewhere. Expanse, 1.90-2.10 inches. 
Early Stages. — Unknown. 
(6) CEneis varuna, Edwards, Plate XXVII, Fig. 8, 6 (The 
Varuna Butterfly). 
Butterfly.— This species is much smaller than any of those 
which have thus far been mentioned. It is found in the prairie 
lands of Montana, North Dakota, and the parts of Canada adjacent. 
It is not uncommon about Calgary. It is light in color on the upper 
side of the wings, and on the under side it is mottled with brown, 
strongly marked with blackish blotches or shades. Expanse, 
1.30-1.60 inch. 
Early Stages.— These await description. 
(7) CEneis uhleri, Reakirt, Plate XXVII, Fig. 12, 6 (Uhler’s 
Arctic). 
Butterfly. — This species is found in Colorado. It is redder 
on the upper side than varuna , and the females are generally 
very richly ornamented with eye-spots on the outer borders of 
both the fore and hind wings. Expanse, 1.43-1.35 inch. 
Early Stages.— These have been most thoroughly described 
and beautifully delineated by Edwards. 
(8) CEneis jutta, Hubner, Plate XXVII, Fig. 5, $ (The Nova 
Scotian). 
Butterfly.— This beautiful species, which is also found in 
Europe, is not uncommon in the State of Maine as far south as 
Bangor, and occurs also in Nova Scotia, and ranges thence west¬ 
ward to Ottawa and the Hudson Bay country. It is one of the 
more conspicuous species of the genus, the eye-like spots upon 
the wings having a very striking appearance. Expanse, 1.80- 
2.10 inches. 
Early Stages.— For a thorough knowledge of these the reader 
may consult the pages of Scudder and Edwards. 
(9) CEneis semidea, Say, Plate XXVII, Fig. 11, 6 ; Plate III, 
Figs. 1, 2, 4, 7, 15, larva; Plate IV, Figs. 4, 5, chrysalis (The 
White Mountain Butterfly).
