systematic order, but )'ou must gather them from various monographs, 

 journals and proceedings, which are not easy to procure. This disheartens 

 the young student. The same is to a great extent also true of butterflies, 

 especially of Noctuidse, 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 accom- 

 modating 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 next meeting would be an inter- 

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

 some member be appointed, so that there may be no conflict, and the 

 whole field be open to him. No doubt the owners of private collections 

 and tlie 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 vigor, patience and order. 



John G. Morris. 



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 pubHcation, which was kindly assented to.

One year ago I gave at the Boston meeting of the Association for the 

 Advancement of Science the results of some experiments in the use of 

 London purple to destroy the codling moth larva, and bisulphide of car- 

 bon in fighting the cabbage maggot and squash borer. These experi-
