Lepidoptera 29 i 
Plebeius aquilo Bdv. 
Argus aquilo Bdv: Icon. 62, 1833. 
Six specimens as follows: Bernard harbour, Northwest Territories, August 
1-25, 1915, 1 female, 3 males (F. Johansen); Bernard harbour. Northwest 
Territories, July 14, 1916, female (F. Johansen); Wollaston land, Victoria 
island, Northwest Territories, July 1, 1915, male (D. Jenness). 
Four other specimens in the National collection at Ottawa from the Yukon 
Territory, two labelled " Burwash creek, Kluane district, Yukon Territory, 
August 8, 1914 (D. D. Cairnes)"; one " Kluane P.O., Yukon Territory, June 23, 
1914 (D. D. Cairnes)," and the fourth " Harrington creek, Yukon Territory, 
lat. 65° 05', long. 141°, July 30, 1912 (D. D. Cairnes)," may possibly be a form 
of the same species. Th^y are larger than the three specimens collected by members 
of the Canadian Arctic Expedition and the underside is more heavily spotted. 
Two of these latter specimens are shown on Plate III at figures 16 and 17, together 
with a male of aquilo from Bernard harbour. Northwest Territories (fig. 18). 
Plebeius saepiolus Bdv. 
Polyommaius scepiolus Bdv.: Ann. Soc. Ent. Fr. (2), X, 297, 1852. 
In the Canadian National collection there is a specimen of this widely 
distributed species from the Yukon: namely from Kluane P.O., Yukon Territory, 
June 21, 1914 (D. D. Cairnes). Fletcher"^ recorded this species from Devil's 
Portage, lower Liard (long. 126° 10'), July 17, 1887 (McConnell), and from 
Finlayson lake, Yukon Territory, July 25, 1887 (Dawson and McEvoy). 
Plebeius shasta Edw. 
Lijcoena shasta Edw.: Proc. Acad. Nat. Sci. Phil. 224, 1862. 
It is of interest to note that in the Annual Report of the Geological Survey 
of Canada, 1887, p. 230b, Fletcher recorded this species from the Upper Pellv 
river (lat. 61° 50', long. 132°), August 3; Lewes river (lat. 62° 20'), 
August 21. Recently I located the specimen collected on August 3, 1887, by 
G. M. Dawson, and it is evident that it should not be referred to as shasta Edw. 
I have included the record under Plebeius scudderi Edw. Shasta was described 
from specimens from California. 
A specimen of this latter species taken at Crane lake, Saskatchewan, June 
2, 1894, by Prof. John Macoun, determined by Dr. J. McDunnough as shasta 
minnehaha Scudd. is in the Canadian National collection. I have not seen any 
examples from more northern localities. 
Genus Glaucopsyche Scudd. 
Glaucopsyche couperi Grt. 
Glaucopsyche couperi Grt.: Bull. Buff. Soc, I, 185, 1874.

Cairnes); on Wagon road, between Whitehorse and Dawson, Yukon Territory, 
1908 (G. M. Stewart); Mayo lake, Yukon Territory, July 28, 1904 (J. Keele); 
between lat. 67° 25' and 66° 30', long. 141°, June 12, 1912 (D. D. Cairnes); 
Dawson, Yukon Territory, 1908 (collector unknown); Frances river, lat. 60° 29', 
July 1, 1887 (G. M. Dawson); Upper Liard river, Yukon Territory, June 27, 
1887 (Dawson and McEvoy). Gravel river. Northwest Territories, below Natla
