202 The Ottawa Naturalist. [January 



Cornell University. Specimens of Nisoniadcs icelus and of 

 N . hrizo were shown and the differences between the two species 

 pointed out. It "is sometimes difficult to decide to which a 

 certain specimen may belong, but there is no doubt if the male 

 can be secured, because of the presence on the hind tibiae of the 

 male of icelus of a long tuft of silky hairs which does not occur 

 in hrizo. Specimens were also shown of Chrysophanus dorcas 

 and epixanihe and of the suffused female of helloides which has 

 been named florus. 



Mr. Metcalfe brought living larvae of a Calopieryx and of 

 Sympetrum ruhicunduluni. He also showed specimens of the 

 imported beetle, Nacerdes melanura which he had found in large 

 numbers on a wharf in the Canal Basin at Ottawa on the 13th 

 July last. Dr. Fletcher stated that it had also been found under 

 similar circumstances in Montreal and Mr. Harrington had 

 once taken it at Ottawa. Mr. Metcalfe said that he had taken it 

 abundantlv and frequently in Toronto among the produce w^are- 

 houses on Front street. Mr. Metcalfe also showed a small 

 collection of insects taken at Nainao, Alberta, by Rev. W. J. 

 Conolly. Among these were noticed a specimen of the Horse 

 Bot Fly, Gastrophilus equi and several specimens of Colias 

 eriphyle. Mr. Metcalfe also made an exhibit of three boxes of 

 determined Homoptera and Heteroptera, among these being 

 some species new to the district recently named for him by Mr. 

 Van Duzee, of Buffalo, and including Ceresa constats which he 

 had found abundantly on three special basswood trees at Hull, 

 P.Q. Telamona reclivata was also from the same tree. Several 

 species of aquatic bugs were examined wnth great interest and 

 many questions were asked as to the habits of the species show^n. 



Mr. Simpson exhibited some specimens of large water bugs, 

 Ranatra,Belostoma, etc., which he had taken at Ottawa some 

 years ago, and also a specimen of Zaitha fiuniinea with the eggs 

 on its back. He also exhibited some photographs by Mr. A. J. 

 Braba^on of the Grand Pacific glacier which he had visited 

 14 years ago, and also one of the same glacier taken b}- Mr. D. 

 H. Nelles during the past summer showing the remarkable 

 recession of this glacier of over 7 miles in 14 years. It was 

 mentioned by Mr. Simpson that this tremendous wasting away 

 of the glacier had been anticipated by Dr. Otto Klotz in 1894. 



Mr. Baldwin showed a box containing insects which he had 

 received at different times from the Ottawa Fruit Exchange, 

 including several species of Blatta, a fine specimen of Periplaneta 

 americana, and a large Lamellicorn beetle. Among specimens 

 taken at Ottawa was a fine specimen of Albuna pyramidalis. 



Mr. Letourneau exhibited some specimens of the Wanderer,
