Abstract of the Proceedings of the Entomological Club 

 of the A. A. A. S. 



The club met August 20th in the State House at Indianapolis, 

 26 persons attending the meetings. The President, Prof A. J. 

 Cook, delivered as his annual address an essay upon teaching En- 

 tomology, which was discussed by Messrs. Weed and Osborn. 



Mr. Weed read a paper upon the life-history of the " evening 

 primrose curculio {Tyhdcrma foveolatumy and upon a Braconid 

 parasite of the same. The paper was commented on by Mr. Web- 

 ster. 



Mr. Fletcher presented some notes upon the injuries caused by 

 the Hessian Fly, the wheat-stem maggot and an undetermined spe- 

 cies of Oscinis. The Oscinis was probably variabilis according to 

 Dr. Williston. 



This note produced extensive discussion by Messrs. Cook, Gar- 

 man. Osborn, Alwo'od and Webster. 



A paper on the subject of American Silk-spinners, by Mr. Ed- 

 ward L. Graef, was read by the Secretary. The author expresses

 useful for the production of native silk, and offers a prize of $50 for 

 the best practical plans for accomplishing this purpose.
