CUPIDO AMIGA (Edwards). 



The tj^pe of this species came from "Mackenzie's River," 



Not recorded by recent observers. The type was received by 



Edwards from Mrs. Ross, who collected it at some point on the 



Mackenzie River." 



NOMIADES COUPERII (Grote). 



This is a common species in the region between Fort Chipewyan 

 and Fort Good Hope. It was feeding- at Fragaria blossoms on the 

 Smith Portage, and also frequented dump situations and mud holes 

 along the trail. Specimens were taken in 1903 at Fort Chipewyan, 

 Smith Landing, Fort Resolution, and Hay River, both sexes being 

 represented in the series. Mr. Preble collected three examples at 

 Fort Good Hope, June 21, 1904. 



A. G. Butler has recorded this species from the "Athabasca River," 

 where Miss Elizabeth Taylor collected it June 5, 1892.^ 



AGRIADES PODARCE (Felder). 



This exquisite little species was quite conuuon on the exposures of 

 Archaean rock near Smith Landing, Athabaska, where I collected a tine 

 series of both sexes in perfect condition, June 11 and 12, 1903. When 

 flushed the flight is weak and low, rarely more than six inches above the 

 rock. Unlike most species of the genus, podarce feels safe onl}' when 

 on the rocks, where it hides most eflectually in the short moss. It is 

 easily overlooked unless sought for, and when on bare rock its detec- 

 tion is almost an impossibility. I often had two or three flush at my 

 feet after having endeavored inefiectually for some time to beat them 

 up. Whenever a passing cloud obscured the sun these butterflies 

 could not be forced to take wing. 



The only previous record for the Athabaska-Mackenzie region seems 

 to be that of Butler,^ who records specimens taken by Miss Elizabeth 

 Taylor at the Rapids of the Drowned, Slave River, July 1, 1892. Miss 

 Taylor's locality is but a very few miles from Smith Landing. The 



range of A. podarce thus appears to be very local.

« In his original dei^cription of omim Edwards nays he received the species from 

 "Mackenzie's River by Mrs. Ross." In the synopsis of North American butterflies 

 at the end of his first volume (Butt. N. Am., 1879, I) Edwards gives the type locality 

 as "Fort Ross, Mackenzie's River." There is no such post as Fort Ross at the 

 present time, nor can I find any reference to it. Edwards probably referred to Fort 

 Simpson, where B. R. Ross was located for many years as factor.
