18 I Canadian Arctic Expedition, 1913-18 



Erebia epipsodea Butl. 



Erebia epipsodea Butl.: Cat. Satyr. Brit. Mus., 80, 1868. 



This species which is evidently rare in northern regions was collected by 

 Mr. J. Keele, in the Yukon Territory, on the Pelly river, below Hoole river, 

 July 5, 1907, 1 male. This specimen is in the Canadian National collection. 

 Two other specimens, 1 male and 1 female collected by the late Dr. D. D. Cairnes, 

 in the Klotassin river area, Yukon Territory, lat. 62 31' to 63 06'; long. 137 

 30' to 139 30', summer, 1916, are in the same collection. These specimens are 

 similar to examples from more southern localities. 



Erebia youngi Holl. 



Erebia youngi Holland: Ent. News, XI, 388, 1900. 



This species was described from material collected between Fortymile and 

 Mission creeks, northeastern Alaska. No specimens were brought back by the 

 members of the Canadian Arctic Expedition, but in the years 1912 and 1914, 

 Dr. D. D. Cairnes, of the Geological Survey of Canada, brought back from the 

 Yukon, nine specimens, five taken in 1912 (all males), and four in 1914 (three 

 males and one female). The 1912 specimens were taken at Siwash creek, 

 international boundary, lat. 65 57' on June 26-30, and the 1914 examples col- 

 lected at Nansen creek, Placer Mining Camp, Yukon Territory, July 4-7. 



In addition to the specimens collected by the late Dr. Cairnes, we also have 

 in the Canadian National collection, a male specimen, collected with other 

 material, the label covering all reading: "Alaska, lat. 59 30' and 141st meridian 

 lat. 69 40' and 141st meridian, June-July, 1912 (J. M. Jessup)." 



In the female the broad dark median band on the underside of the second- 

 aries is more conspicuous than in the males owing to the fact that the basal and 

 submarginal areas are much paler in colour. In one of the males the submar- 

 ginal reddish spots on the upperside of the secondaries are almost absent. 



When describing E. youngi, Holland stated that the species is not far from 

 E. dabanensis Erschoff. It certainly is close to this latter species as figured by 

 Elwes 1 . A male from Siwash creek, Yukon Territory, is illustrated on PI. IV, 

 fig. 10. 



Erebia magdalena Stkr. 



Erebia magdalena Stkr.: Bull. Brooklyn Ent. Soc., Ill, 35. 



In the Canadian National collection there are two specimens of an Erebia 

 from the Yukon which we have placed under magdalena Strk. One of these 

 specimens, a male, has been recorded by Fletcher 2 as this species. It was 

 collected by Mr. Jos. Keele of the Department of Mines, who captured it " on 

 mountain 12 miles up Rackla river, August 2, 1905." 



Mr. Keele informed me recently that the specimen was collected on a rocky 

 situation above timber line, the elevation being about 6,000 feet. The other 

 specimen, a female, was collected by the late Dr. D. D. Cairnes, of the Geological 

 Survey, at Nation river, Yukon Territory, lat. 65 30', long. 141, on July 24, 

 1912. 



( 'ompnring these two specimens with three examples of magdalena presented 

 to Fletcher some years ago and collected by Bruce in Colorado and now in the 

 Ottawa collection, they differ as follows: the male which is in poor condition, 

 being rubbed, is smaller than the Colorado male, measuring 45 mm. with wings 

 expanded, the former being 49 mm. Otherwise both specimens seem to be 

 similar. The Yukon female is also smaller than the two Colorado females in
