division of their habitats into meadow ponds, woodland ponds, brooks and 

 springs was proposed and illustrated by series of specimens peculiar to each 

 environment. 



Mr. Shoemaker exhibited his large collection of water beetles. 



Dr. Felt communicated two summaries relating to gall midges and 

 mosquitoes. 



Mr. Dow spoke of collecting Corixidae in the island of Jamaica, where no 

 natural body of water suitable to their development is found, but where never- 

 theless vast numbers occur and must presumably have adapted themselves to 

 other than their natural environment. 



On account of the late hour, the chairman announced that discussion of 

 the papers that had been read would be postponed till the following meeting. 



Meeting of November s, 1912. 



A regular meeting of the New York Entomological Society was held No- 

 vember s, 1912, in the American Museum of Natural History, at 8.15 P. M., 

 President Dr. Raymond C. Osburn in the chair and eleven members present. 



The curator announced that work on the local collection of Rhynchophora 

 would commence on Saturday afternoon, November 9 ; also that current num- 

 >bers of all entomological journals, by arrangement with the librarian of the 

 American Museum, would be found on file in the meeting room. 



Mr. Maximilian C. Marshall, of No. 3035 Ocean Ave., Sheepshead Bay, 

 L. I., was nominated for active membership. On motion the by-laws were sus- 

 pended and Mr. Marshall was immediately elected. Dr. Osburn donated a 

 duplicate paper from his library to the library of the Society. 



Under the title " Notes on Collecting in the Northwestern States and in 

 the Canadian Rockies," Dr. Osburn described the journey he had made, start- 

 ing at the end of May from Minneapolis through North Dakota, Montana and 

 Yellowstone Park, to Tacoma, Seattle and Vancouver, returning via Canadian 

 Pacific Railway, with stops at Revelstoke, Kaslo, Kootenay, Glacier, Field and 

 Laggan, illustrating his remarks by photographs thrown on the screen by radi- 

 opticon. Dr. Osburn's visit to the Red River of the North, thirty miles north 

 of Fargo, Dak., was particularly for the capture of Gomphus cornutus, and his 

 success will be mentioned in the Journal. In the Yellowstone Park, insects en- 

 crusted with lime were found in the hot springs, and will also be mentioned in 

 the Journal. At Kaslo, Dr. Osburn met Mr. Cockle and collected the first day 

 with him on the bluff above Kootenay Lake, and on the succeeding day up stream 

 and partly along line of old railroad, finding ^shna interrupta var. interna and 

 a species of Cnterebra. At Glacier splendid collecting was found on the slopes 

 of Eagle Peak and in a damp mountain meadow where, on July 15, Syrphids 

 were very abundant. The season was rather too early for dragonflies, which 

 would have been more abundant later and up to the middle of August. From 

 Field a side trip was made to Emerald Lake ; on the road through a forest of 

 lodge pole pines Tabanus osburni Hine, a most pestiferous horse fly, not hesitat- 

 ing to attack humans as well as horses, was very abundant. From Emerald Lake
