MEETINGS OF THE ENTOMOLOGICAL CLUB OF THE 

 AMERICAN ASSOCIATION FOR THE ADVANCEMENT 



OF SCIENCE. 



According to previous announcement, the first meeting of this club 

 was held in the rooms of the Detroit Scientific Association, on the 10th 

 of August, at 2 : 30 p. m., Dr. J. L. Leconte, President in the chair, Prof. 

 C. V. Riley, Secretary. The attendance was large, including S. H. 

 Scudder, Esq., Cambridge, Mass., Vice-President, and Messrs. A. R. 

 Grote, Buffalo. N. Y., W. Saunders, London, Ont., B. P. Mann and E. 

 P. Austin, of Cambridge, Mass., Prof. E. S. Morse, Salem, Mass., J. A. 

 Lintner, Albany, N. Y., E. A. Schwarz, H. G. Hubbard and B. Walker, 

 of Detroit, Dr. A. E. Dalrymple and Dr. J. G. Morris, Baltimore, Md., 

 Prof. A. J. Cook, Lansing, Mich., Dr. Hoy, Racine, Wisconsin, Clinton 

 Roosevelt and Geo. Dimmock, Springfield, Mass., B. D. Sanders, J. C. 

 Holmes and Win. Provis, Detroit, J. T. Ison, Cleveland, Ohio, and 

 others. 



President Leconte, in a few opening remarks, stated the objects had 

 n view in the formation of this club. They were chiefly to cultivate 

 closer personal relations among those interested in Entomological pur- 

 suits, many of whom were widely separated by distance, to exchange views 

 and record observations, and to exhibit specimens of interest. He hoped 

 that the meetings would not only be fruitful in these respects, but that, 

 seeing'the importance of Entomology in its relation to agriculture, some 

 good to the country might flow from the deliberations. 



Mr. Wm. Saunders mentioned the fact of the unusual scarcity of 

 insects of the Saw-fly family (Tenthredinidas) throughout western Ontario, 

 especially those destructive to fruit, naming the Gooseberry Saw-fly 

 (Nematus ventricosus ) and the Pear Tree Slug (Selandria cerasi). Both 

 these insects, although enormously abundant and destructive in 1874, had 

 been quite scarce in 1875. He called for suggestions as to the cause, his 

 own impression being that this diminution had been caused by the severity 

 of the late winter and spring. 



Prof. Cook, of Lansing, Mich., had not observed any remarkable 

 scarcity of these species in his neigborhood. 



Prof. Riley had remarked their almost entire absence in some locali- 

 ties, and their comparative abundance in others.
