244 ^ HE Ottawa Naturalist. [March 



Mr. Keele gave an account of his last summer's work in the 

 Klondike country proper, which he explained was not as good a 

 locality for insects as that where he was working in 1905. He 

 showed some most interesting photographs of the country and 

 of animals, which had been taken during the expedition. Some 

 pictures of Dall's Big-horn, a cow moose protecting her two 

 calves, a Canada Lynx, a percupine, and a group of ptarmigan 

 on a mountain side, were much admired. Mr. Keele related some 

 interesting incidents with regard to each picture. 



Mr. Nelles, of the Alaska Coast Strip Survey, explained the 

 nature of the country where he was working last summer. A 

 large number of insects had been taken by Mr. Theo. Bryant, an 

 enthusiastic entomologist who was one of the party. 



Mr. Baldwin showed the galls of Eucosoma scudderiana, a 

 common gall on the Canada Goldenrod, and also the moths, and 

 several parasites. Dr. Fletcher spoke of the checkered history 

 of this species, which by mistake was thought to have been reared 

 by Walsh from willow galls and was originally described under 

 the specific name saligneana for this reason. It had been referred 

 to two or three genera at different times but was for the present 

 resting in the genus Eucosoma. Mr. Baldwin also exhibited a 

 large specimen of the West Indian Spider usually spoken of as 

 the Banana Tarantula, on account of the frequency with which 

 it is introduced with bunches of that fruit. 



Mr. Simpson showed living specimens of the small red lady- 

 bird beetle, Adalia bipunctata, and spoke of the enormous 

 abundance of these insects at the present time in the Dominion 

 Astronomical Observatory and during the past summer on the 

 Experimental Farm. This was attributed to the great abundance 

 of plant lice of all kinds in the early part of the season, the 

 lady-bird beetles feeding upon the plant lice and performing a 

 most useful part in the balance of nature. Soon after midsummer 

 it was noticed that the pupae of the Adalias were infested by 

 minute hymenopterous parasites to such an extent that probably' 

 not more than two or three per cent of the pupae produced 

 beetles. 



Dr. Fletcher showed a photograph by Mr. E. A. Carew-
