EREBIA ROSSII (Curtis). 



This beautiful Arctic .species, tlie type of wliicli came from Boothia 

 Felix, seems to have been taken in Mackenzie by only two collectors. 

 A^"hite records it from the "Arctic Coast between 67^"- and 68°," 

 where Richardson collected it in 1848;'^ while Elwes records three 

 specimens taken by the Hanbury expedition — a pair on the Barren 

 Grounds (114^' W., ^ST' 40' N.), July 14, and one at Point Epworth, July 

 11, 1902/ 



EREBIA DISA Thunberg. 



Three males and a female were collected })y Mr. Han))ury at Point 

 Epworth, July 11, 1002. Elwes considers them to be much nearer 

 specimens of E. dlsa from Finland than to our var. ma)tcmui<: from 

 Alaska/ 



EREBIA YOUNGI Holland. 



Mr. Preble collected two specimens at Fort McPherson, July 8, 1904, 

 thus extending- the range of this species east of the Rocky Mountains. 

 These examples differ in no respect from Alawka specimens of yo%ingi. 



EREBIA EPIPSODEA (Butler). 



Doctor Fletcher informs me that the Canadian government collection 

 at Ottawa contains this species from the vicinity of Dunvegan, Peace 

 River, Athabaska, where J. M. Macoun collected specimens in the 

 summer of 1903. 



E. epipsodea is a mountain species, and probably occurs over most of 

 western Athabaska. 



COENONYMPHA OCHRACEA (Edwards). 



This dainty little ])utterfly was common at Fort Providence from 

 July 3 to 8, 1903, where, on bright mornings, numbers could be seen 

 flitting about on the open rocky hillside near the river. I easily 

 collected a good series of both sexes. Nearly all were perfectly fresh, 

 indicating that the species had not been flying many days at that point. 



C. ochracea has previously been recorded from Red Deer Ri^'er, 

 Alberta, but apparently from no farther north. 



COENONYMPHA TIPHON var. MIXTURATA Alpheraky. 



Elwes considers two males and a female taken by Hanbur}' on Dis- 

 mal Creek (Kendall River), east of Great Bear Lake, Jul}^ 30, 1902, as 

 most closely approaching the Kamchatkan form.''
