ing as we went. We lunched at the same place as the day be 

 fore and spent some time sweeping the banks of the creek for 

 neuropteroid insects, hymenopterous parasites, etc., and exam 

 ined the bed of the stream for aquatic larvae. Here Mr. Caudell 

 secured a specimen of the water beetle .Amphizoa and some 

 more Blepharocerid larvae similar to those I found the day before. 

 About a mile above Ainsvvorth and near the road is a long pond 

 of several acres area called Loon Lake. Here were captured a 

 number of dragonflies, representing several species. We reached 

 Ainsworth late in the afternoon and returned to Kaslo in the 

 evening. 



Bear Lake {altitude J ,800 feet) , July 20 and 29. A sta 

 tion on the Kaslo & Slocan Railway twenty miles west of Kaslo. 

 Here are two small mountain lakes from the smallest of which, 

 Fish Lake, Kaslo Creek takes its origin. The other lake, known 

 as Bear Lake, is just west of Fish Lake. Mr. Caudell and I 

 visited this locality on July 20 in company with Mr. Cockle, and 

 spent the afternoon collecting near the two lakes and along the 

 railroad track. Butterflies and bees were found around the 

 flowering plants, and the grass, weeds, small trees and bushes 

 yielded a large number and variety of insects from sweeping. 

 Neuropteroid insects were particularly abundant, especially cad- 

 disflies, mayflies and Chrysopidse, and this was the only locality 

 where we caught Sialis. We spent the night here and next 

 morning climbed the mountain north of Bear Lake by switch 

 back trail to London Hill Mine at the summit. On a subsequent 

 trip (July 29), Mr. Caudell and I sugared for moths along the 

 railroad between Fish and Bear Lakes and secured about 100 

 specimens. Two-thirds of these belonged to a single species 

 {Noctua sierrce Harvey), not uncommon at Kaslo. Hardly any 

 of these moths were peculiar to the locality, but were the same 

 species we had collected at Kaslo earlier in the season. 



London Hill Mine, Bear Lake {altitude 7,000 feet}, July 

 21, 28 and 20. As stated in the last paragraph, Mr. Cockle, 

 Mr. Caudell and I climbed the mountain north of Bear Lake on 

 the morning of July 21 and, as the day was warm and sunny, 

 spent a few hours collecting at the summit near the abandoned 

 London Hill Mine. The forests on the mountains about Bear 

 Lake have been completely destroyed by fires and only the 

 charred and dead tree trunks remain standing. There was little 

 collecting, therefore, on the way up. Around the summit the 

 trees are stunted, grow in isolated and straggling patches, and 

 have not been reached by the fire. These afforded very fair beat 

 ing and sweeping, and the many blossoms covering the treeless 

 areas attracted a variety of bees, flies and alpine Lepidoptera. 

 On the extreme summit a swarm of Bombyliid, Tachinid and
