Chionobas Macounii, it would seem, cannot bear the degree of temperature that Jutta 

 may be safely exposed to. Mr. Fletcher sent me eggs of the species, and they hatched, 

 but I lost the larva after the second moult. The weather at Quebec was, I presume, 

 too mild for them. However, the larvse seemed to have survived longer with me than with 

 others, so I give my notes upon them. And here I would observe that the notes of Mr. 

 Beutenmiiller upon the young larva, in the Canadian Ent&mologist for August last, 

 agree with my description of it after the first moult. The first moult probably escaped 

 Mr. Beutenmiiller's observation. 



Notes on Chionobas Macounii. 



Newly Hatched Larva. — One-tenth inch long. Head, large, honey-yellow, indented, 

 marked transversely with two rows of light brown spots. Several dark brown warts 

 on each side of the head. Body, bluish white ; dorsal, sub-dorsal, side, and spiracular 

 lines dark-amber. Two dots of the same colour, one on each side of the dorsal line, in 

 each segment. Anal projections. Spiracles, dark amber. Legs, semi-transparent. 

 Moulted August 13th. 



Larva after 1st Moult. — Two-tenths of an inch long. Head whitish, indented, 

 having six longitudinal rows of pale brown dots. Body cream-white ; dorsal and sub- 

 dorsal lines cinnamon ; side lines brown ; spiracular line pale cinnamon ; spiracles black. 

 Moulted September 3rd. 



Larva after 2nd Moult. — Length one-quarter of an inch. Head indented, whitish 

 with a faint purple tinge, retains the six longitudinal rows of brown dots. Six black 

 warts on each side. Body cream-coloured ; dorsal line amber, then at both sides at 

 intervals a chocolate line, an amber line, and again a chocolate line. Spiracular line a 

 lighter shade of chocolate. A similar line just above the legs. Spiracles black, the 

 first and last on each side larger than the rest. After this moult the insect became 

 sluggish, refused to eat, and gradually withered away. 



Doubtless many interesting particulars of the effects of heat upon the insect life 

 might be accumulated if entomologists would record their observations in regard to 

 them. 



Mr. Harrington thought that the difference of atmospheric pressure had a 

 good deal of effect upon insects brought down from high altitudes to the lower 

 levels, as well as the change of temperature. As an instance of the fatal effects 

 of extreme heat, he mentioned that he had found the snout beetles Pissodes strobi 

 and Conotrachelus nenuphar in quantities upon a zinc roof at Ottawa in summer, 

 and that when the sun got round to them they were usually all killed by the heat 

 of its rays ; he had found as much as a quart of these beetles in a corner of the 

 roof from this cause. 



Mr. Fletcher mentioned that he had had some caterpillars of Chionobas 

 Macounii which had attained their full growth. They were reared from eggs 

 obtained last year at Nepigon (a full account of the expedition in search of these 

 eggs is given in the Annual Report for 1888, page 85). The caterpillars hibernated 

 in their second stage, passing the winter out of doors on sedges entirely without 

 protection. In the early part of the winter the cold was very severe and the 

 thermometer fell to 20° below zero ; afterwards the caterpillars were covered with 

 about four feet of snow. 



The Rev. W. A. Burman, of Winnipeg, was elected a member of the Society. 



After spending some time in the examination and discussion of various speci- 

 mens brought by members, the meeting adjourned to meet again next year in 

 London, Ontario.
