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. They 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. 



Polyommatus saepiolus 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 1 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. 



Lyccena 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 jCanada, 1887, p. 230b, Fletcher recorded this species from the Upper Pcllv 

 river (lat. 61° 50', long. 132°), August 3; Lewes river (lat. 62° 20'j, 

 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.
