 "The chrysalis is either oblong and somewhat angular on the 

 sides, with the head notched, and two rows of pointed tuber- 

 cles 011 the back, or short and rounded, 

 with the head obtuse." (Harris). Chio- 

 nobas is found on Alpine summits and 

 in the Arctic regions and on subarctic 

 mountains. C. semidea Say (Fig. 190; 

 Fig. 191, hind wing) lives on the summit 

 of Mount Washington. It feeds on 

 lichens. 



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. Bore Schiodte (Fig. 195) we 

 have collected in Hopedale, Labrador, 

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



Satyrus Alope Fabr. is our largest spe- 

 cies. It is dark brown, with a broad,

 It is abundant in open fields in July and August. The pale 

 green larva is striped with dark, the head is round, and the tail

 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
