also true of butterflies, especially of Xoctuidce and of other orders of insects, although the 

 want is supplied in Lepidoptera more fully than in any other. But even this order, 

 beyond the Diurnals, although hundreds of species are described, has not been brought 

 together in systematic arrangement. The material is at hand, and nothing is wanting but 

 a competent editor and an accommodating publisher to bring out a series of works which 

 would contribute immeasurably to our progress. 



My second suggestion is, that it would be interesting to know the extent, character 

 and condition of the larger public and private collections in the country, with a mention 

 of the varieties they contain. This might embrace two sections, those of our own species 

 and those of foreign countries. A paper on this subject for the next meeting w^ould be an 

 interesting contribution, and I hope some gentleman will furnish it ; or let some member 

 be appointed, so that there may be no qonflict, and the whole field be open to him. No 

 doubt the owners of private collections and the curators of public ones would cheerfully 

 render him their counsel and aid. 



And now, gentlemen, congratulating you upon our meeting again, let us proceed to 

 our business and prosecute it with vigour, patience and order.

At the conclusion of the address a vote of thanks was tendered to the President, 

 coupled with the request that the copy be sent to the Canadian Entomologist for publica- 

 tion, which was kindly assented to. 



On Saturday morning the Entomological Sub-section was again in session, when the 

 following papers were read : 



The Egg Case of Hydrophilus triangularis, by C. Y. Kiley ; on the Oviposition of 

 Prodoxus decijnens, and also one on the Cocoon of Gyriniis by the same author. Follow- 

 ing these a paper was presented by B. P. Mann, entitled Suggestions of Co-operation in 

 Furthering the Study of Entomology ; and another by C. Y. Riley, on New Insects 

 Injurious to American Agriculture. 



In this latter paper the author called attention to several insects hitherto unknown 

 as injurious, which during the present year have proved very destructive to one crop or 

 another. Such hitherto unknown and unreported injury is either caused by, 1st, imported 

 species; 2nd, native species previously known but without destructive habit; 3rd, un- 

 known or undescribed species. The author gave an account of the injury which had been 

 done to clover plants by a beetle, Phytonomus vunctatus, in Yates Co., New York. The 

 cocoons of the beetle were found on the ground in the fields, but the beetles were diflicult 

 to find on account of their shyness, as they fall to the ground when approached. Mr. 

 Riley also reported that much injury had been done to corn in South Carolina and Georgia 

 by a borer which was probably the larva of a Pyralid moth. 



After the reading of papers an informal discussion on Entomological subjects took 

 place. 



Mr. A. J. Cook remarked that Heliothis arniigera had attacked corn in Michigan for 

 the fii*st time in 1880. That was a very wet year, w^hereas this year had been very dry, 

 and this season the army worm, Leucania unipuncta, had been observed injuring it for 

 the first time. 



Mr. AY. Saunders said that the imagos of the army worm, Leucania unipuncta, had 

 been unusually abundant in Ontario during the summer, and had been seen at sugar in 

 great numbers, and referred to the fact that the destructive brood of this insect was not 

 the first brood. Mr. Cook had found the moths similarly abundant in Michigan. 



Mr. Cyrus Thomas stated that he had positive proof that the eggs of Leucania uni- 

 jmncta had been deposited in fields of oats. He also said that wet weather was very 

 favourable for the development of this insect. 



Mr. J. A. Lintner spoke of the great abundance of the clover-seed midge, Cecidomyia 

 leguminicola, which was rapidly spreading over a large area. Mr. B. P. Mann considered 

 that the rearing of insects in the house tended to prolong the life of the larva?, and to
