Genus CEneis 



(5) CEneis ivallda, Mead, Plate XXVII, Fig. 9, $ (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, $ (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. 50-1.60 inch. 



Early Stages.— These await description. 



(7) CEneis uhleri, Reakirt, Plate XXVII, Fig. 12, $ (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, 1.45-1.55 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. u, $ ; Plate III, 

 Figs. 1, 2, 4, 7, 15, larva; Plate IV, Figs. 4, 5, chrysalis (The
