Proceedings of the Entomological Club of the A. A. A. S. of 

 Indianapolis, 1890. — Dr. Weed presented a short paper on the habits of 

 JJxiis concavus. 



Prof. Hargitt called attention to early observations on the Canker-worm. 

 He also spoke of a Cecidomyia infesting the tops of Solidago, and also 

 presented "Notes upon Cermatia forceps.'''' 



Prof Webster spoke of the predaceous habits of Cermatia and its prey- 

 ing upon the Croton bug. Mr. Fletcher had observed the insect with Mr. 

 Howard at Washington. Its mode of capturing the Croton bug before 

 devouring it was remarkable. It sprang over its prey, which was thus 

 encaged between many curved legs. He thought that Mr. Hargitt's suc- 

 cess in keeping alive the specimens he had conhned in a tin canister, was 

 more due to the moisture thus secured than the darkness. He under- 

 stood that this insect was a lover of damp places, like many other myriopods. 



The Club then proceeded to the election of officers for the ensuing year, 

 which resulted as follows: 



President, Prof Herbert Osborn, Ames, Iowa. 

 Vice-President, Miss Mary E. Murtfeldt, Kirkwood, Mo. 

 Secretary, Clarence M. Weed, Columbus, Ohio. 



Prof Osborn presented a paper on "The use of Contagious Diseases 

 in destroying Injurious insects." 



Prof Atkinson spoke of some insects of Alabama. 



Dr. Weed read a short paper on the oviposition of Dectes spinosus in 

 Ambrosia trifiida. 



Prof Cook presented some notes on the insects of the year. He said 

 Cut-worms and Saw-flies had been very injurious. The larvae of ^geria 

 tipuliformis was attacked with a fungus growth like that attacking the 

 white grub. The foliage ot the quince and cherry were injured by the 

 first brood of larvae of Cherry Slug. Road dust was applied with excel- 

 lent results. Dr. Weed presented a short paper on Psepheniis lecontei, 

 which, he stated, he had found on the shores of Lake Erie. 



Club adjourned to meet in connection with the A. A. A. S. ne.xt year.

Secretary. 



The Entomological Society of Washington, Oct. 2, 1890. — Messrs. 

 J. M. Stedman, Nathan Banks and F. W. Mally, were elected members 

 of the Society. 



Under exhibition of specimens and notes. Dr. Fox exhibited a specimen 

 of a small spider, belonging to the genus Episiniis, which was stated by 

 Dr. Marx to be an undescribed species. 



Dr. Marx called attention to two spiders new to our fauna, one belong- 

 ing to the European genus Histopona taken at Penn-Mar, and also re- 

 ceived from .South Florida, and the other, a new genus, of uncertain po-
