24 I Canadian Arctic Expedition, 1913-18 
Brenthis frigga alaskensis Lehm. 
Argynnis frigga form alaskensis Lehm.: Macrolepidoptera of the World, 
. (Seitz), V, 424, 1913. 
Seven specimens as follows: Barter island, north coast of Alaska, July 4 
and 11, 1914, 2 males, 3 females (D. Jenness) ; Collinson point, Alaska, July 10, 
1914, 1 female (F. Johansen) ; west of Konganevik (Camden Bay), Alaska, 
July, 1914, 1 male (F. Johansen). Accompanying the specimen from Barter 
island is a note by Mr. Jenness, which reads as follows: " Flying on tundra in 
sunshine; light N.W. breeze; temperature 50° F." 
I have compared the females with the original figure of alaskensis in the work 
referred to above. They agree fairly well with this illustration. A female from 
Collinson point, Alaska, is shown on Plate V, fig. 1. 
Six examples were brought back by the Northern Party of the Canadian 
Arctic Expedition, three males and three females. These were collected at 
Armstrong Point, Victoria island. Northwest Territories, June 20 to July 11, 
1916 (J. Hadley).

In the Canadian National collection there are two specimens from the fol- 
lowing localities in the Yukon Territory: 96 miles from Whitehorse on Kluane 
road, near Marshall creek, June 15, 1914, 1 male (D. D. Cairnes); Pelly river, 
below Hoole river, July 5, 1907, 1 female (J. Keele).

Argynnis improba Butl.: Ent. Mo. Mag., XIII, 206, 1877. 
Thirty-four specimens from the following localities: West of Konganevik 
(Camden bay), Alaska, July, 1914, 5 males, 1 female (F. Johansen); Barter 
island, Alaska, July 1, 2, 4, 5, 11, 1914, 9 males, 5 females (D. Jenness); 
Bernard harbour, Northwest Territories, July, 1916, 5 males, 7 females (F. 
Johansen); Port Epworth, Coronation gulf, July 15, 23, 1915, 1 female. 1 male 
(J. J. O'Neill). 
Three of the above specimens, namely, one male from Barter island, one male 
from west of Konganevik and one female from Barter island, were forwarded 
to Mr. H. J. Elwes, of Colesborne, Cheltenham, Eng., who very kindly compared 
them with the series in the British Museum. He reported that the specimens 
agreed precisely with examples collected by Hanbury on the same coast further 
east. 
The series above listed is an excellent one. Most of the specimens are in 
fairly good condition. The males vary in wing expanse from 31 mm. to 36 mm. 
and the females from 33 mm. to 37 mm. The ground colour of the former shows 
marked variation. In some of the specimens the colour is very close to hazeP, 
in one much brighter, more of a vinaceous-rufous- and in the others dull tawny. 
In the brighter coloured examples the median band on the upper side of both 
the primaries and secondaries is very conspicuous. The spots about midway 
between the median band and the outer margin vary much in size and in a few 
specimens are joined forming a distinct band. 
The underside of the males is fairly constant, the chief differences being 
on the secondaries, namely in the number of pale, slightly bluish-coloured 
scales present beyond the reddish-brown median area, 'in some examples these 
scales being noticeably abundant and forming almost a wide marginal band
