Lepidoptera 15 i 



Oeneis cairnesi, n. sp. 



Upperside ochraceous-buff 1 lightly washed with brown, noticeably so 

 along veins and outer margin, the markings of the underside showing through 

 particularly on the secondaries; costa whitish, mottled with black. 



Underside: primaries, centrally similarly coloured to upper side but rather 

 more brownish; costa, apex and outer margin to near inner angle, whitish with 

 dark brown mottlings. In the limbal area between veins 5 and 6 there is a 

 distinct dark brown ocellus with white pupil. Secondaries whitish with brown 

 mottlings, the median band mostly dark brown and well defined, paler in the 

 centre. Area on either side of the median band almost wholly whitish. About 

 midway between the median band and the outer margin there are four round, 

 white spots, the two central ones being much smaller than the two outer ones, 

 which latter are about half the size of the ocellus on the underside of each 

 primary. The four spots are margined with brown, the outer ones distinctly so. 



Fringes whitish, checkered with brown. Clothing of palpi black and 

 grayish intermixed. Antennae brown with white scales, knob orange-brown. 

 Body blackish. Genitalia shown on Plate 1, fig. 6. 



Alar expanse 42 mm. 



Type, a male, from the White river district, Yukon Territory, lat. 61 55', 

 long. 141, July 16, 1913 (D. D. Cairnes); in the Canadian National collection. 

 Named in honour of the late Dr. Cairnes who collected many interesting species 

 when on northern explorations for the Canadian Geological Survey. 



Paratypes, one male and two females (expanse 44 mm.) from the same 

 locality. The females are slightly paler in colour than the males and the median 

 band on the underside of the secondaries is not so well defined as in the type. 



Before describing the above, I submitted a specimen to Dr. Dyar with a 

 request that he compare it with his species 0. nahanni. This he very kindly 

 did reporting that it differed chiefly from his species in being too light in colour, 

 in having no ocelli on hind wings above and the markings on these latter 

 wings being more of an open character. 



The upperside of the type of 0. cairnesi is shown on PL IV, fig. 6, the under- 

 side of the same specimen on PL II, fig. 7. The underside of one of the female 

 paratypes is shown on the latter Plate at fig. 8. 



Oeneis brucei var. yukonensis, new variety. 



Differs from 0. brucei from Colorado in being smaller in wing expanse, 

 in having a conspicuous submarginal row of yellowish spots on the upper side 

 of both primaries and secondaries, in the costa being almost concolorous with 

 wings not white or whitish as in the typical form, and in the median band on 

 the underside of the secondaries being narrower. On either side of the median 

 band the whitish areas are wider and thus more conspicuous, and there is in 

 addition a distinct submarginal blackish line on the underside of the secondaries. 



Alar expanse, 41 mm. 



Type, a male, from Klutlan glacier, Yukon Territory, elevation 8,200 feet, 

 June 14, 1913 (E. W. Nesham). Paratypes, three males and two females 

 collected in the same locality by Mr. Nesham on June 13-15 at elevations of 

 8,200-8,500 feet; wing expanse, 38-41 mm. The paratypes are in general 

 similar to the type. One of the female paratypes has on each primary two 

 ocelli, one between veins 2 and 3 and the other between veins 5 and 6. All 

 the types are in the Canadian National collection. The upperside of the type 

 is shown on PL IV, fig. 3; the underside of the same specimen on PL II, fig. 9. 

 On this latter plate is also shown at figure 10 the upperside of the female paratype 

 with ocelli. The genitalia of one of the male paratypes are shown on PL 1,
