satisfactory. \V. E. Britton gave an account of experiments with gases for 

 fumigating nursery trees, already noted fnun anotlicr source (K. S. K., 1!). \>. 

 lor>.i). 



\V. Newell and T. ('. Tauisen outlined some results obtained in spraying 

 experiments to destroy the foliage of cotton in the fall. In these experiments 

 coMunon salt, bicarltonate of soda, lye, hydrochloric acid, white arsenic, iron 

 suli>hate, and other materials were used. The iron sulphate gave quite satis- 

 factory results. Some growth takes jilace after defoliation, but this is not 

 regarded as a serious matter. 



W. D. Pierce discussed The Economic r.earing of the Study of Parasites of 

 the Cotton-Boll Weevil. It is suggested that cultural operations can be so 

 organized as not to interfere with the hibernation or multiidication of the 

 parasites of the weevil. C. T. Brues called attention to The Correlation Be- 

 tween IIai)its and Structural Characters Among Parasitic Hymenoptera. Some 

 species of hymeuojiterous jtarasites show a very limited range of hosts, while 

 others adapt themselves to a greater number of hosts. The latter are on the 

 whole more decidedly dominant species. 



E. D. Sanderson gave some of the results of a studj' of the codling moth 

 in New Haniiishire. It is estimated that 8S per cent or more of the total 

 benefit of spraying was due to the effect on the first brood and through it on 

 the second brood. It is believed that in New England the first brood may 

 be controlled by spraying when the petals drop. F. I>. Washburn described 

 the process of Egg Laying of Emiion.sca mali. Notes on Some Insects of the 

 Season were given by H. Osborn for Ohio, G. P. Welden for Maryland, E. P. 

 Felt for New York, and W. Newell and A. II. Rosenfeld for Louisiana.

 society, reports of which are included in this number of the proceedings, papers 

 were read on various entomological subjects, some of which are of considerable 

 economic importance. Among these papers mention may be made of the fol- 

 lowing :
