1905 ENTOMOLOGICAL SOCIETY. 73 



Louise and Hector district. Cliionobas Cliryxus was also plentiful every- 

 where. Cli. jutta only at Lake Louise and in Lake O'Hara valley, half way 

 down. 



On the 29th of August I left camp and started homewards. I had one 

 day at Banff, where I got V. antiopa, just out of chrysalis, and Colias Chris- 

 tina — ;^very common, but considerably the worse for wear. Then I had one 

 day at Ottawa, and half a day at Montreal, which concluded a most agree- 

 able expedition. But the only district that I thoroughly worked, and where 

 I got most of the insects that were to be had, is the central chain of the 

 Eockies, on both sides of the Kicking Horse Pass. 



I cannot conclude without expressing my acknowledgments to Dr. 

 Fletcher of Ottawa, Mr. Wolley Dod of Calgary, Mr. Wheeler (C.P.R. 

 Survey), and Mr, Cockle of Kaslo, for the great kindness and attention they 

 showed me. And I must also make mention of James Simpson, my guide 

 and packer, who ran my camp, took care of me, and helped me to catch but- 

 terflies. I never saw a better man with the net nor one with a quicker eye for 

 any variation in an insect, and I can honestly recommend him to any ento- 

 mologist wishing to collect in the Rockies. 



Catalogue of Butterflies Taken in Canada During 1904. 



1. Parnassius clodius. Common on the Island of Vancouver, where I 

 was too early for it. I took it first on the Pacific coast early in June at sea 

 level, or but little above, and at Greenwood, about 200 miles inland, at the 

 end of June. 



2. P. smintheus. This is the common representative of the genus 

 throughout the Pocky Mountains, It was common at low elevations all 

 through June, at Nelson and Greenwood, and at Kaslo in July. I took two 

 or three specimens of the fine dark female variety Hermodur. In August, 

 in a mountain gorge near Mt. Assiniboine, at a height of 7,000 feet, at 

 least, well above tree level, I found var. Behri just appearing (August 13th). 

 No females were then out, and I never met with the insect at Lake O'Hara, 

 or in the Yoho valley later in the month. 



3. Papilio eurymedon. Common on the Pacific coast and eastwards as 

 far as Kaslo. In Vancouver Island it is very abundant. 



4. P. rutulus. Common all through the west of British Columbia. Mr. 

 Wolley Dod does not appear to have taken it at Calgary. 



5. P. gJaucus var. turnus. Not so common as Rutulus, but more widely 

 distributed. It was very common at Greenwood, near the boundary, in June. 



6. P. zolicaon. One specimen only, close to the Pacific coast at the 

 boundary. It very nearly resembles Machaon, but Dr. Dyar gives Machaon 

 as a different species, represented in America by var. Alias Jca, taken m 

 Alaska only. 



7. Pontia Occident aUs. Very common all through British Columbia on 

 the western slope of the Divide right down to the coast. 



8. Var. calyce is the* high mountain form of occidentalis, and is much 

 paler on the under side, and the veins yellower. 



9. P. rapce is an emigrant from Europe, and not a welcome one. This 

 was the first butterfly I caught on landing at Quebec in May. It is common 

 all through Canada to the Pacific. 



10. P. napi. Another European emigrant, universally common but 

 nowhere destructive.
