 and black at the edge; the other mouth parts much infuscated. Ocelli black at base. 



Body uniform cream color with a faint, rather broad, darker, dorsal stripe and a 

 slenderer, distinct, pale yellowish stripe extending the entire length of the body. Black- 

 ish fuscous spots are found along the stigmatal line and somewhat irregularly be- 

 neath the lateral band at the posterior limit of each segment. Papillae concolnrous

 penultimate joint black or blackish. Prolegs greatly infuscated, especially apically 

 and upon the outside. Spiracles black, set in a small black Held surrounded with a 

 fusco-ferruginous areola. Length of the body, 21 mm. ; breadth of the same, 2.8 mm. ;

Distribution (29: 5). This butterfly is interesting as being our only 

 subarctic skipper (unless Erynnis manitoba may lay some claim to such dis- 

 tinction), a member of both the Canadian and Huronian faunas, and 

 though found in comparatively few localities has an immense distribution, 

 almost wholly in the dominion of Canada, where it has been found at An- 

 ticosti and southern Labrador (Couper), Godbout rare (Corneau), Lake 

 Mistassini (Fletcher), Quebec (Bowles) , Bevan's Lake (D'Urban), Comp- 

 ton (Gosse), Ottawa (Billings), Bobcaygeon, Ont. (Fletcher), Moose, 

 at the southern extremity of Hudson Bay, common (Haydon, teste Weir), 

 St. Joseph's Island and Sault St. Marie, Lake Superior "quite common" 

 (Bethune), Nepigon, not uncommon (Fletcher, Scudder), Lake Winni- 

 peg (Edwards), Rocky Mountains (Brit. Mus., and more recently 

 Macoun),Lake La Hache (Crotch), Vancouver Island (Fletcher) and 

 Alaska (Edwards). It has also been found in our own territory in Cali- 

 fornia* (Behrens), and Edwards also states that it occurs in New 

 York, probably in the Adirondacks. 



It occui's also, in New England, being not uncommon in the higher valleys 

 of the White Mountains, as along the Glen road and along the roads into 

 the ravines and through the notches in the vicinity of Crawford's and of 

 Fabyan's (Sanborn, Scudder and others) ; and further, at Norway (Smith) 

 and Lake Chimo, near Bangor, iNIe. (Braun). 



Oviposition. The only eggs I have heard of were those obtained by 

 Mr. Fletcher and myself at Nepigon, where an enclosed female laid a 

 couple of eggs on grass. Mr. Fletcher also raised the larva from one 

 gently pressed from the oviduct of the same moribund female. The eggs 

 hatch in ten or twelve days. 



Food and habits of the caterpillar. Not only were the eggs laid 

 by the female on grass, common lawn grass, Poa pratensis, but the cater- 

 pillar was carried to maturity by Mr. Fletcher on the same, while females 

 caged over plantain, Plantago, on which the allied Pamphila palaemon is 

 said to feed, refused to lay eggs thereon. Moreover, when the caterpillars 

 hatched, one was placed by Mr. Fletcher on grass and one on plantain ; 



•By accident the color on the map intended for this point has been carried too far east.
