Lepidoptera 17 1 



The specimens collected by Messrs. Cairnes and Hadley arc in general 

 similar to the series from Bernard harbour and Cape Krusenstern. The band 



on the underside of the female collected at lat. 65° 10' is faint, as is also the 

 reddish area on both upper and lower sides of primaries. 



Erebia rossi Curt. 



Hipparchia rossii Curt.: Ross' Second Voyage N.-W. Pass, App., 67, 1835. 



One specimen, a female, from Wollaston Land, Victoria island, Northwest 

 Territories, July 22, 1915 (D. Jenness); PI. IV, fig. 9. 



On each forewing of the specimen, above, are three ocelli; the two in the 

 sub-apical area are close together, but entirely separated, similar as in the 

 specimen figured by Curtis; the lower spot is the larger. About midway between 

 this latter spot and the hind angle is the third spot which is about the size of 

 the upper of the two spots. The spots are ochraceous-orange in colour, the 

 black pupil showing only in the largest of the three spots. The two upper 

 spots are more distinct on the underside, being slightly paler in colour, of a 

 more uniform size, and each having a distinct black pupil. The third spot is 

 only faintly visible on the underside. The colour of the upperside of the wings 

 is close to light seal brown; the underside is similar but the outer central portion 

 of the primaries is reddish, the discal area being suffused with a paler brown 

 than that of the hind wings. The underside of the secondaries are banded as 

 in Elwes' figure 1 . 



Two other specimens in the Canadian National collection, both males, one 

 from Kluane P.O., Yukon Territory, June 23, 1914 (D. D. Cairnes), the other 

 from West branch of the Thelon river, Northwest Territories, July 6, 1900 

 (J. Tyrrell) also appear to be the same species. The one from Kluane is- very 

 similar to the Wollaston Land specimen but that from the Thelon river is dif- 

 ferently marked approaching Elwes' fig. 2 in the publication referred to. 



Erebia disa Thun. 



Papilio disa Thun.: Diss. Ent. Ins. Suec, II, 37, 1791. 



Two specimens taken as follows: Port Epworth, Coronation gulf, North- 

 west Territories, July 15, 1915, 1 male, 1 female (J. J. O'Neill). 



The former specimen is much like the figure of disa on plate 37h, vol. 1, of 

 Seitz's Macrolepidoptera of the World but is much darker brown in colour. The 

 median band on the underside of the secondaries is well defined, the area on 

 either side being greyish-white. The female is in a poor state of preservation. 



In the Canadian National collection there are specimens from the Yukon 

 and Northwest Territories, bearing the following labels: — 75 miles from White- 

 horse, near Canyon river, Yukon Territory, June 11, 1914, 1 male (D. D. 

 Cairnes); Whitehorse, Yukon Territory, (McLaughlin); Lansing river, Yukon 

 Territory, June 24, 1905, 1 female (J. Keele); Siwash creek, Yukon Territory, 

 lat. 65°59', long. 141°, July 29, 1912 (D. D. Cairnes); Gravel river. Northwest 

 Territories, June 27, Julv 20, 1908, 3 specimens, 2 males, 1 female (J. Keele); 

 Black river, Yukon Territory, lat. 66° 34', June 18, 1912 (D. D. Cairnes). 



There is a noticeable variation in these latter specimens, not only in 

 the size of the spots on the primaries, but also in the colour of the lower side of 

 the wings and the faintness or otherwise of the median band on the secondaries. 

 In the specimen from near Canyon river, for instance, the colour of the underside 

 of the secondaries is almost wholly dark brown, very similar to the colour of the 

 reverse side, excepting the outer margin which is greyish. 



Some of these examples should doubtless be referred to the var. mandnus 

 Dbl. and Hew. The specimen from Lansing river, was recorded by Fletcher as 

 the var. mancinus in the Entomological Kecord for 1905. 2
