NO. 1488. BUTTERFLIES OF BRITISH AMERICA— GARY. 439 



BRENTHIS MYRINA (Cramer). 



This large Brent his was common in a gniss}- tamarack swale near 

 the mouth of the North Nahanni River, Jul 3^ 18 to 17, 11K>3, where I 

 captured a single specimen. The species was not noted elsewhere in 

 the north l)v either Mr. Prel)le or myself. 



Butler records specimens of B. myrinn collected l^y Miss Elizabeth 

 Taylor at the Rapids of the Drowned, Slave River, Jul^^ 1, and at Fort 

 Good Hope, July 18, 1892." 



This species is common in portions of Alaska, and has been taken in 

 the region south of Hudson Ba}-; thence westward to the Lake Winni- 

 peg region, and also at Edmonton, Alberta (latitude S-t^). It undoubt- 

 edly has a general distribution in the lake country of Athabaska and 

 southern Mackenzie, which future work will prove more satisfactorily. 



(?) BRENTHIS BELLONA ( Fabricius) . 



Formerh^ listed b}^ Edwards from """Great Slave Lake", prol)ably in 

 error. ^ It scarcely seems possi])le that this southeastei'n species 

 ranges to the latitude of Slave Lake, almost in the Hudsonian zone. 



BRENTHIS PALES (Denis and Schiffermiiller). 



This European species is very rare in America, having been recorded 

 onl}' from Alaska previous to Mr. IClwes's review of the Hanbury col- 

 lection. Among these butterflies were three males and a female of 

 yalei^ from the Barren Grounds (Arctic coast, 15 to 30 miles east of 

 the mouth of Coppermine River), taken July 16 to 18, 1902. Elwes 

 considers these specimens quite typical, having compared them with 

 Alpine and northern Siberian examples.'' 



BRENTHIS CHARICLEA (Schneider). 



Mr. Hanbury took this species at all localities where he collected on 

 the Barren Grounds in 1902. Elwes remarks upon the great amount 

 of individual variation exhil)ited l)y the different specimens, and figures 

 a melanistic male from CUuipman Island, a small male from Dismal 

 Creek, very pale, and a large female from Point P^pworth, the latter a 

 most peculiar aberration.'' I am informed l)y Francis A. Heron that 

 in addition to the Hanlniry series the British Museum collection con- 

 tains three males and one female of B. charldea from Great Slave 

 Lake, collected in Jul}-, 1894, by A^". G. Cumming.
