Genus Brenthis 



tips, and marked with light yellow on the interspaces beyond 

 the end of the cell. The hind wings are dark ferruginous, shad- 

 ing into purplish-gray on the outer margin, with a whitish quad- 

 rate spot on the costa near the base, marked with two dark 

 spots, and a bar of pale, somewhat obscured spots, forming an 

 irregular band across the middle of the hind wings. 



$ . — The female does not differ greatly from the male, except 

 that the spots on the under side of the hind wings stand forth 

 more conspicuously, being lighter in color and better defined. 

 Expanse, 1.65-2.00 inches. 



This pretty little butterfly occurs in Labrador, across the con- 

 tinent as far west as northern Alaska, and is also occasionally 

 taken upon the alpine summits of the Rocky Mountains as far 

 south as Colorado.

Butterfly. — Pale fulvous on the upper side, with the dark 

 markings on the inner half of the wing narrow, but more or less 

 confluent. The dark markings on the outer part of the wing are 

 slighter. The fore wings are a little angled on the outer margin 

 below the apex. On the under side the fore wings are pale ful- 

 vous, mottled with purple at the tip and on the outer margin. 

 The hind wings on this side are ferruginous, mottled with 

 purple. Expanse, 1. 65-1. 80 inch. 



Egg. — The egg of this species is similar in form, size, color, 

 and markings to the egg of B. myrina. 



Caterpillar.— The caterpillar also in its early stages closely re- 

 sembles myrina, but in its mature form it differs in not having the 

 spines on the second segment of the body lengthened as in that 

 species. 



Chrysalis. — The chrysalis, which is represented in Plate V, is 

 bluish-gray in color, marked with dark spots. The life-history 

 has been given us by several authors. 



This butterfly is very common in the whole of the northern 

 United States, as far south as the mountain-ranges of Virginia, 

 and occurs throughout Quebec, Ontario, and British America, as 

 far west as the foot-hills of the Rocky Mountains. It flies commonly 

 with B. myrina, the only other species of the genus found in the 

 densely populated portions of our territory, from which it may be
