1911 EJsTTOMOLOGICAL SOCIETY. 43 



The collector who knows something about the habits of the insects he gathers 

 alongshore is usually struck with the apparent preponderance of carnivorous forms. 

 All of the dragon-flies and bugs, nearly all of the beetles and the larvae of many 

 flies, are of strictly carnivorous habits and are very much more in evidence than the 

 herbivorous May-flies or midge larvae or those algae-feeding beetle larvae of the 

 family Haliplidae that has recently been demonstrated to be herbivorous. 



The lecturer then showed many lantern slides illustrating species of May-flies, 

 beetle larvae and caddis-worms that are being studied especially at the Biological 

 Field Station of Cornell University. He discussed the varying reproductive capacity, 

 length of life, food and shelter requirements of these species, and showed in con- 

 clusion the possibilities of artificial increase by rearing in pure cultures and the 

 possibilities of conservation of the natural supply of these excellent items of fish 

 food by providing proper shelter and by protecting the foraging grounds. 



The Chairman, Mr. C. C. James, expressed the pleasure that all present had 

 derived from the address and the surprise that all shared in at the importance of 

 aquatic insects as regards the provision of food for fishes. A vote of thanks to Prof. 

 Needham was moved by President Creelman, seconded by Dr. C. Gordon Hewitt, 

 and heartily adopted by the meeting. 



SECOND DAY'S SESSION— FRIDAY, NOVEMBER 4th, 1910. 



The first portion of the morning was spent in the Society's part of the College 

 Museum, and was devoted to an inspection of the extensive collections of Lepidop- 

 tera and Coleoptera and the specimens brought by the members. Among the various 

 interesting examples presented may be mentioned a large collection of beetles cap- 

 tured upon foliage in illustration of Mr. F. J. A. Morris's paper; these specimens 

 were beautifully mounted and carefully labelled. Prof. J. M. Swaine exhibited a 

 series of specimens of Scolytid beetles and their work as wood-engravers and timber 

 destroyers. 



Dr. Hewitt exhibited a case containing the partial life-history of the Spruce 

 Budworm (Tortrix fumiferana). This contained moths, larvae, chrysalids, and 

 several species of parasites, as well as drawings of the mature larva and end of tvdg 

 showing the winter shelters of the young larvae. In a separate case was exhibited 

 the characteristic work of the caterpillars. Dr. Hewitt also placed on view a case 

 containing the work oT six different species of Chermes which had been donated to 

 the Division of Entomology by Miss Edith M. Patch, of Orono, Maine, and speci- 

 mens of the parasite, Tropidopria conica, reared from Eristalis. 



Mr. Gibson exhibited a case containing rare Noctuids and Arctians. Among 

 these were Stretchia plusiiformis and Apantesis michabo from Hymers, Ont. ; 

 Momophara comstocki, from McNab's Island, N.S.; Sphinx pereUgans, from Wel- 

 lington, B.C. ; and a series of moths of the genus Xylina from the Ottawa district. 

 An inflate of the mature larva of Estigmene prima was also shown, which had been 

 reared from eggs obtained at Shawville, Que., by Mr. A. F. Winn. 



The following were noted among the specimens exhibited by Mr. Lyman : — 



Grapta gracilis, from the Wliite Mountains. 



Argynnis montinus, CTiinohas semidea, Colias interior, Parchnohia wochei? 

 and Anarta schoenJierri from Mt. Washington. 



Hepialus gracilis from the White Mountains. 



Also the following from Hymers, Ont., received from Mr. Horace Dawson : — 



A beautifully suffused specimen of Argynnis atlantis.
