ing any growth. The moth is double brooded, and has not been observed in that local- 

 ity beyond the precincts of the island. Mr. Scudder also presented a plate with enlarged 

 drawings of the insect and its work. 



Mr. Comstock had met with the same insect on P. inops, and had found that the 

 tips of the branches of the Pines were usually covered with a web. He had also found 

 aD other species of Retinia infesting the twigs of P. rigida. This latter bores into the small 

 twigs of the tree, from which exude masses of resin. The larva lives within the branch 

 upon the wood, and before pupating forces its way through the mass to the outside. 



Mr. Bassett had observed some fifteen years ago, about Waterbury, Conn., that the 

 common White Pine (Pinus strobus) was greatly injured at the tips of the branches by 

 Pissodes Strobi, but for the last ten years this pest had almost disappeared. Mr. Kiley 

 referred to another Tortrix affecting the Junipers on Long Island, Dapsilia rutilana, a 

 European species recently imported. 



Prof. Fernald stated that he had received from Oregon and Washington Territory, 

 specimens of Pietinia duplana and sylvostrana identical with the European forms, and 

 further referred to the fact that in America the species of Tortricidaa are more abundant 

 in the West than in the East. 



Mr. Grote called the attention of the membersto the ravages of Xephopteryx Zimmer- 

 mani, which he believed had inflicted more injury on youug 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 

 nurserymen 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 larvae and chrysa- 

 lids 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 Northern American Tortricide. Many of them were being destroyed by the ver- 

 digris 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 ScoUopteryx libatrix was very widely distributed in this- 

 country as well as in Europe, being found here from Hudson's Bay to the Southern 

 States. He also referred to Mr. Grey's discovery that Limenitis arthemis, disippus, Ursula 

 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. Lintner held that it was premature to conclude that the different species of 

 Limenitis are identical until it could be proven positively by rearing the one supposed 

 species from the eggs of the other. 



Mr. Scudder exhibited a piece of a woody root which was represented as coming 

 from the interglacial beds of clay near Toronto, Ontario. This root proves by micro- 

 scopic examination to belong to a species of Juniper and is bored by an insect, probably 

 a Scolytus, but one which differs materially in its habits from any known species now 

 existing. Mr. Scudder also referred to the abundance of insect remains which he had 

 found in the peat deposits on the Island of Nantucket ; from one mass of about a cubic 

 foot he had obtained 300 fragments of Coleoptera, among which were several which he 

 had been unable to refer to any species now known to exist; a number of these speci- 

 mens were shown to the members.
