Lepidoptera 17 1 
The specimens collected by Messrs. Cairnes and Hadley are 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) ; PL 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' figured 
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 d'lsa 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, (McLaughhn); 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, July 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 tlark 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. viancinus 
Dbl. and Hew. The specimen from Lansing river, was recorded by Fletcher as 
the var. mancinus in the Entomological Record for 1905.^
