Genus Erynnis 



most hesperid larvae, and sluggish in proportion to its stoutness. 

 It does not make a nest, but conceals itself between the leaves of 

 grass at the point where they unite with the stem, 

 and is not very difficult to discover. 



Chrysalis. — The chrysalis is elongated, cylin- 

 drical. Our knowledge of this stage is not very 

 accurate as yet.

Butterfly, $ . — The upper side of the wings is 

 depicted in the plate. On the under side the wings Neuration' 66 of 

 are paler, the fore wings fulvous on the cell, pale the genus Eryn- 

 gray at the apex and on the outer margin. There ""' enlar S ed - 

 is a black shade at the base of the primaries, and a black streak 

 corresponding in location to the discal stigma on the upper side. 

 The hind wings are pale ferruginous, except a broad streak along 

 the inner margin, which is whitish. All the light spots of the 

 upper side of both wings reappear on the under side, but are more 

 distinctly defined, and are pearly-white in color. 



?.— The female, on the under side of the fore wing, has the 

 black discal streak replaced by a broad ferruginous shade. The 

 hind wings are darker, and the light spots stand forth more con- 

 spicuously upon the darker ground. Expanse, $, 1.25 inch; 9, 

 1.30 inch. 



Early Stages. — These remain to be ascertained. 



The Canadian Skipper is found across the entire continent 

 north of a line roughly approximating the boundary between the 

 United States and the Dominion of Canada. Along the Western 

 Cordilleras it descends into the United States, as far south as 

 Colorado and northern California.

Butterfly. — The upper side of the wings in both sexes is suffi- 

 ciently well delineated in the plate to obviate the necessity for 

 description. On the under side the fore wings are pale fulvous, 

 black at the base and ferruginous at the tip, the ferruginous 

 shade interrupted by the subapical pale spots, which on this side 

 of the wing are pearly-white. The hind wings are deep ferrugi- 

 nous, obscured on the inner margin by long pale-brown hairs. 

 From the base to the end of the cell there is a broad silvery-white
