NOTES ON A FEW BUTTERFLIES FOUND AT KASLO AND 

 IN NORTHERN BRITISH COLUMBIA. 



BY J. W. COCKLE, KASLO, B. C. 



It has been suggested that notes on the occurrence of unusual butter- 

 flies should be published, and, as the following will show, I have been 

 fortunate in making several interesting captures. 



Chio7iobas gigas Butler. — A remarkable male specimen was taken at 

 Kaslo in thick timber and near the water's edge, at an altitude of i^Soo 

 feet, on the first of June, 1908. All previous records of this species were 

 from the coast mountains at high altitudes. Mt. Arrowsmith, on Vancouver 

 Island, and Mt. Cheam, on the lower mainland, were the only known 

 localities. Wright, in his " Butterflies of the West Coast," says gigas is 

 found on the bald knobs of the mountain tops, but never in the valleys or 

 lowlands ; so the occurrence oi gigas in the valley of the Kootenays at a 

 low altitude adds interest to the record. 



The specimen on the upper side agrees with specimens from Mt. 

 Arrowsmith, but on the under side there is a marked variation, the 

 primaries being identical with the figure of ivallda, Mead., which Wright 

 figures and reports as occurring in the Sierras at an elevation of 10,000 ft. 

 This variation applies only to the maculation ; the ground colour is like 

 gigas, a rich nut-brown, and not pale straw colour as in ivallda. 



Everes comyntas Godart. — One male, Kaslo, B. C, May 30, 1904, 

 Considerable doubt may be expressed as to this record, but the specimen 

 is identical with eastern material, and has no resemblance to aviyntula, 

 which is a common species here. I cannot claim this as a record of 

 farthest west, as I was shown a specimen which I identified as comyntas, 

 in the collection of Mr. A. H. Bush, of Vancouver ; this was taken on the 

 Stickeen River, on the north coast of British Columbia. 



Colias Kootenai. — A probable new species, May 17 to 20, and fall 

 brood to Oct. 9. This has been confounded with eriphyle, Edw., but does 

 not agree with Edwards's description. It emerges about three weeks 

 earlier than eriphyle in both broods ; the margins are narrower, the 

 expanse less than that of eriphyle, and the colour of the secondaries on 

 the underside is greenish and not deep orange-yellow, as stated in 

 Edwards's description oi eriphyle. Unfortunately the Colias group is in 

 great need of revision by some one who is broad-minded enough to assign 

 all the various named species to their proper place. I have secured a 

 large series of Colias in order to compare them with this reputed new 



June, 1910
