74 THE REPORT OF THE No. 19 



11. Synchloe creusa. Of this insect I only took a solitary specimen at 

 Banff, June 2nd. It was probably nearly over, and I saw no more of it. It 

 is taken on the Pacific coast and crosses the Divide at Banff. Mr. Wolley 

 Dod inclines to think that it merges into ausonides at Calgary. I consider 

 my specimen from Banff to be quite distinct. 



12. S. ausonides. Widely distributed but nowhere common. I took one 

 or two specimens at Penticton, Greenwood, Kaslo, and Nelson, but never 

 found it plentiful anywhere. It is common at Calgary. 



13. S. sara. Common all through the south-western districts of British 

 Columbia. I did not get either of its varieties. It does not occur at Calgary 

 and probably does not cross the Divide. 



14. EuryTmis (Colias) Meadii var. EJis. Scattered rather sparingly over 

 all the high mountains of the main chain of the Rockies at an elevation of 

 6,500 to 7,500 feet. I took the greatest number on the steep slopes of a 

 mountain above Hector Lake. It also occurred at Lake Louise, Mt. Assini- 

 boine and mountains above Simpson E,iver. 



15. E. eurytheTne var Keewaydin. Of this butterfly I only took two 

 specimens at Victoria, June 6th. 



16. Var. eriphyle is the commonest Colias all through AVestern Canada. 

 I took it everywhere, and without any great variation. The beautiful orange 

 type of the species and var Ariadne I did not meet with. I also took two 

 in the Eraser Canyon in May, and a fine fresh one at Banff August 30th. 



17. C. philodice is also very common and widely distributed. I never 

 took it at a high level, but it is the commonest butterfly at Montreal and 

 Ottawa in September. At Ottawa (September) a fine white female variety 

 was common. 



18. E. Christina. At Banff only, where it was flying in plenty August 

 30th, but in very bad order, and the females far worse than the males. It 

 is common at Calgary. 



19. E. alexandra. One specimen only, from Greenwood, near the bound- 

 ary. 



20. . Very plentiful in the valley from Greenwood to Midway. It 



also occurs through the whole of British Columbia south of Lake Okanagan. 

 The color of the under side is much yellower than in the type (Alexandra), 

 in which the under side is greenish and very pale. Dr. Rebel pronounces 

 the specimens I sent him to be Behri (Edwards), but in this opinion Mr. 

 Elwes does not agree (nor do I). 



21. E. interior. I took it only at Kaslo, where it is not very common. 

 Mr. Wolley Dod takes it in some numbers at Calgary, where it flies among 

 the spruce in July, which is just where and when I took it at Kaslo. 



22. E. peJidne var. Minismi (Elwes). This a very common butterfly 

 over the whole of the higher Rockies, flying from 5,000 to about 6,000 feet. 

 The females vary considerably, the white ones being commoner than the 

 yellow. It flies all through August. (Dr. Rebel pronounces this insect to 

 be not Pelidne, but STcinneri (Barnes), which he considers to be a good 

 species.) 



23. E. nastes. Common at very high levels on every mountain I went 

 up in the whole chain of the Rockies. It varies considerably and I think 

 that those from Mt. Assiniboine, the most southern point at which I found 

 them, are paler and yellower than more northern specimens. 



24. Euptoieta Claudia. One specimen only taken at Mt. Assiniboine in 

 August, close to the lake, at 5,000 feet or more. It is a southern butterfly,
