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. Jennesspwhich 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 hazel 1 , 

 in one much brighter, more of a vinaceous-rufous 2 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
