2G8 THE CANADIAN ENTOMOLOGIST. 



Professor Galloway followed with a paper on various insecticide 

 substances, with which he had been experimenting for a number of years 

 past, many of them in lines which had not hitherto been worked to any 

 extent. He discussed particularly the kerosene emulsion made with lime, 

 with resin wash, and with Bordeaux mixture. He also described a new 

 method of making resin wash, devised by one of his field agents in 

 Florida, which, briefly, consisted in using purer caustic soda, causing a 

 much m.ore rapid formation of the resin soap. Various other mixtures of 

 possible insecticide value were also suggested. The paper was accom- 

 panied by the exhibition of a large series of vials, illustrating the various 

 mixtures and combinations described by the author. The communication 

 was generally discussed, and the important point emphasized that none of 

 the emulsions were as perfect or as permanent as the standard milk and 

 soap emulsions in common use, although some of them are possibly of 

 value for immediate application. 



Mr. Webster's paper on "Spraying with Arsenites vs. Bees" was 

 read, in the absence of the author, by the Secretary. The conclusions 

 arrived at were that arsenic is always present in the abdomens of bees 

 frequenting recently sprayed blossoms, and more or less of it reaches the 

 honey sacs ; and that bees are, therefore, liable to be poisoned by spraying 

 the bloom of fruit trees. He claimed that his experiments were the first 

 to show conclusively that actual poisoning does result to bees under the 

 conditions mentioned. 



In the discussion, Mr. Lintner stated that even in the event of actual 

 harm resulting to the bees, the question is still an open one, for the reason 

 that many noxious insects frequenting fruit blooms are also destroyed. 

 The paper was further discussed by other members. 



Mr. Southwick presented a paper on economic entomological work 

 in the parks of New York City, in which he described the general 

 character of the means employed to control destructive insects in the 

 principal parks of New York ; he also gave some notes on the occurrences 

 of and damage due to the principal insect pests with which he had to 

 contend. A general discussion of the paper followed, which was partici- 

 pated in by most of the members present. 



Mr. Southwick followed with a second paper on the Wood Leopard 

 Moth in the parks of New York, giving an historical account of the insect, 

 its present status, the nature of the injury, the plants affected, and the 

 means he had adopted to exterminate the pest. He stated that this is a
