6 THE CANADIAN ENTOMOLOGIST 



July 16th. — This day I took a good mixed bag, increasing 

 my Somatochlora series of minor, alhicincta and franklini. Two 

 astarte were on the wing, a female that I took at rest on a rock, 

 and a male by the easy system practiced the previous day. I also 

 caught one N. yarrowi, a fine pair of Vanessa milberti, a 5. galii, 

 two C. nastes, two CEneis chryxiis and saw a Neoarctia beani, that 

 I much wanted for Mr. Bowman, flying low over the shale. I 

 walked to the eastern end of the ridge, but a strong south wand 

 was blowing and nothing much resulted. 



Mentioning wind, reminds me that a breeze on a mountain 

 top — even on glorious, hot, cloudless days, is the rule rather than 

 the exception. This has evidently created in mountain-top but- 

 terflies the protective and pretty habit of lying over on their sides 

 when at rest. C. nastes and 0. brucei are much given to this at- 

 titude, but I think all the other species taken adopted it more or 

 less. Even when temporarily there was no wind, or the spot was a 

 sheltered one, it made no difference. Instinct told them to "lie 

 low," and lie low they did. 



On returning to camp I saw a largish Somatochlora flying 

 by a jack pine, and netted it successfully when it settled. It 

 proved to be a male, not of the odd female of the 14th {cingulata) 

 but a seventh species, viz., semicircularis. 



July 17th. — This was to be my last day on the mountain. 

 Some time during the morning, i. e., after I had left for the top. 

 "Dutch" was to come up to pack the outfit back to Nordegg. I 

 rose at 6.30 and reached the top at 10 o'clock. Soon after I saw, 

 but failed to capture, a butterfly that I greatly desired, viz., 

 Papilio nitra. It flew straight past me just out of reach. I did 

 get, however, a male Somatochlora to pair with the large, white- 

 ringed female of the 15th, cingulata; a lot of females of S. franklini, 

 and a mixed lot of butterflies that have already been mentioned. 

 At 2.45 I started down for Nordegg, took several fresh Colias 

 Christina and a Pieris occidentalis en route, and arrived at 4.30. 



While my story of the mountain is finished, I might record 

 a few captures made during the next two days in the valley. On
