PROCEEDINGS OF THE NEW YORK ENTO- 

 MOLOGICAL SOCIETY. 



Meeting of March 2, 1909. 



Held at the American Museum of Natural History. Vice-President E. B. 

 Southwick in the chair, with fourteen members present. 



The librarian reported the receipt of the following exchanges : 



Wiener Entomol. Zeitung, XXVI H, No. i. 



Mittheil. Naturh. Mus. in Hamburg, XXV. 



Verhandl. d. k. k. Zool. Bot. Gesel. Wien, LVHI, No. 10. 



Societas Entomologica, XXHI, Nos. 21-22. 



Plans were discussed for compiling a list of the insects of New York State. It 

 was the general opinion that it would be best to use the New Jersey List of Insects 

 as a basis to which additions could easily be made. On motion of Dr. Love, the 

 librarian was empowered to procure an interlinear copy of the New Jersey list to be 

 used by the members in recording data. 



The librarian announced that the exchange list was becoming too large and that 

 the Society was receiving a great deal of non-entomological literature. He requested 

 that the exchanges be more restricted. The matter was referred to the publication 

 committee. 



Mr. Pollard announced that the Council of the New York Academy of Sciences 

 had granted Mr. Kearfott's request for a grant of $400.00 to carry on the work of 

 publishing a monograph of the Tortricidse of the World. 



Mr. R. P. Dow spoke on the subject of " A Side Line Study of Larvae of Several 

 Orders" in which he detailed the work carried on by his brother and himself in de- 

 tecting the presence of certain chemicals in the bodies of various larvae. They en- 

 deavored to determine to what extent certain characteristic plant acids and juices 

 could be detected mainly by taste. He proceeded to use this as a basis for a theory 

 of classification in which he placed those insects highest which elaborated the more 

 complex materials from their natural foods. 



Mr. I. Matausch exhibited several excellent colored drawings of larva; and adult 

 stages of some Membracidte, and spoke concerning his experiences, begun during 

 July and August, 1907, in rearing members of this group. He had succeeded in 

 rearing Catnphyletichia curvata, collected on golden rod, from a very young stage. 

 He remarked that the moulting of this insect takes place during the early morning 

 hours. From observations made in the field he came to the conclusion that it was 

 rather sedentary in habit, remaining on the same stem for long periods of time. He 

 found that ants were especially fond of the exudations of Vandmia arcuafa, which 

 occurs on the locust. He mentioned the food plants of many of the Membracidre. 



Mr. H. G. Barber exhibited a collection of palearctic Hemiptera recently pur- 

 chased from Staudinger and Bang-Haas. In his remarks he dealt particularly with 

 the following species of the collection which occur both in Europe and the United
