mountains. C. semidea Say (Fig. 190 ; 



Fig. 191, hind wing) lives on the summit 



of Mount "Washington. It feeds on 



sedges, according to Scudder. 



Mr. Scudder, has in the accompanying 



figures, closely exhibited the differences 



between the Alpine and Arctic species 



of Chionobas. C. Jutta Moschler (Fig. 192) we took in 



Northern Labrador ; it extends as far south as Quebec, accord- 



ing to Edwards. C. Chrixus Doubleday, (Fig. 193) is found 



on Pike's Peak, Colorado Territory ; C. Calais Scudder (Fig. 

 194) is found on Albany River, Hudson's 

 Bay ; C. Sore Schiodte (Fig. 195) we 

 have collected in Hopedale, Labrador, 

 as also C. (Eno Boisd. (Fig. 196). 



Satyrus Alope Fabr. is our largest spe-

 Catskill mountains, occupies higher ground, according to Mr. 

 Edwards, while S. Alope, which prevails southward, is found 

 in the lowlands and valleys. S. Nephele is smaller, darker, and
