The Ottawa Naturalist. [February 



and a specimen of the Rocky Mountain Locust, Melanoplus 

 spretus, which occasionally has done harm in Manitoba and the 

 North-west, but which has not been seen for a year or two. 



Mr. C. H. Young showed a most exquisite collection of 

 mlcrolepidoptera (about three hundred specimens) which had been 

 taken during the past summer at Meach Like, Que., and around 

 Ottawa. All the members present were delighted with the beauti- 

 ful and neat way in which these specimens were set and labelled. 

 Many of the specimens had been reared by Mr. Young from 

 larvffi, and records kept of their food plants. 



Mr. W. J. Wilson submitted an interesting small collection 

 of insects taken on the Hudson Bay slope during the past season. 

 He stated that the season had been an exceptionally poor one for 

 all kipds of insects, except perhaps for mosquitoes. 



Mr. Andrew Halkett read some interesting notes made m the 

 Arctic regions as Naturalist of the Neptune Expedition, under Mr. 

 A P. Low. The large larv^ of the Bot Fly of the Cariboo were 

 shown, and a description was given of the way in which these re- 

 pulsive creatures occur in the backs of the cariboo. They are oval 

 in shape, over an inch in length and about half an inch m width. 

 The body is covered with short spines, and the creatures must be 

 the cause of great suffering to the animals while they are present 

 beneath the skin. When mature they force their way out through 

 a hole irt the skin, in a similar way to the warbles seen on the 

 backs of cattle, and fall to the ground. Later, the mature fly 

 (Edemogena tarandi. L., appears. It is a hairy fly three-quarters of 

 ^n inch in length, of a yellowish colour, bearing a black band 

 across the middle of the thorax, connecting the bases ot the wings. 

 The abdomen is yellow at base but has two-thirds at the tip 

 reddish-brown. This insect Mr. Halkett spoke of as the 

 ''Tooktoo Fly," which he named from the Esquimaux word tor 

 the cariboo. Parasites from the walrus and seal were also shown, 

 as well as some beetles and caddice flies. 



Mr D A. Campbell showed some eggs, and larvae in the first 

 stage, of the Cecropia moth, pointing out that the piliferous 

 tubercles were of a different nature in the different stages. 



Mr. J. W. Baldwin showed a series of the Meadow Brown 

 butterfly [Satyrus nephele), which illustrated the exceeding vari-
