TFIE CANADIAN ENTOMOLOGIST. L95 



Mr. Grote called the attention of the members to the ravages of 

 Nephopteryx Zimmermani^ which he believed had inflicted more injury on 

 young pines than any other insect ; it is found throughout the northern 

 and north-western parts of New York State. Mr. Grote laid particular 

 stress on the fact that the European pines imported and sold by nursery- 

 men are much infested, and desired to call public attention to this matter. 

 With regard to the use of Paris Green as an insecticide, he thought that 

 it was doubtful whether the injury caused by it was not greater than 

 would occur from the Potato Beetle were it allowed to go unmolested ; 

 and instanced the loss of a stallion valued at $2,500, poisoned by Paris 

 Green, and also referred to the frequent injuries to animals and man 

 reported in the newspapers. This opinion was opposed by other members 

 present, who stated that but for the use of Paris Green or some such 

 poison, it would be impossible in some sections of the country to grow 

 potatoes at all. 



Prof. Fernald referred to a Tortrix found in Maine, Tortrix nigridia, 

 which had very much injured the pines there ; he had collected a large 

 number of the larva; and chrysalids of this insect, and from them, besides 

 the moths, had obtained many ichneumon parasites and also several hair 

 snakes. Prof. Fernald embraced this opportunity of calling the attention 

 of the members to the condition in which he had found the types of the 

 North American Tortricida?. Many of them were being destroyed by the 

 verdigris formed by the corrosion of the pins on which they were mounted, 

 and in some instances this verdigris has accumulated to such an extent 

 as to burst the bodies of the insects. To avoid this difficulty he has used 

 japanned pins, and found that when thus coated they remained free from 

 corrosion. 



Mr. Grote remarked that Scoliopteryx libatrix was very widely dis- 

 tributed in this country as well as in Europe, being found here from Hud- 

 son's Bay to the Southern States. He also referred to Mr. Grey's discovery 

 that Limenitis arthemis, disippus, ursida and proserpina are connected by 

 intermediate individuals, and that this indicated that they had not long 

 been separated from a common stock, and expressed the opinion that 

 arthemis was probably nearest the original form. 



Mr. Scudder, referring to the same subject, regarded disippus as pro- 

 bably the original type of this species. 



Mr. Lintner held that it was premature to conclude that the different
