264 THE CANADIAN ENTOMOLOGIST. 



He spoke of the fact that the boundaries of the States represented by 

 official entomologists are artificial, and that in consequence matters of 

 distribution and other broad questions are seldom touched. This fact 

 and the danger of unnecessary duplication of work, and other reasons, 

 called for organziation, and this organization should be of flexible form, 

 leaving each individual free to meet the special requirements of his indi- 

 vidual work, and at the same time helping to concentrate the surplus effort 

 which should be contributed to the accomplishment of common ends. 

 He suggested that a committee on co-operation propose a list of subjects 

 in which co-operative effort is desirable. These subjects should then be 

 attacked by volunteers, who should report to the committee. In this way 

 he thought that the benefits of organization might be obtained without 

 the surrender of individual initiative. 



The address was discussed by Messrs. Osborn, Smith and Webster. 

 Messrs. Osborn, Smith and Garman were appointed a committee of three 

 to consider the recommendations contained in the address. 



Messrs. Edward H. Thompson, of Tasmania, R. Allan Wight, of New 

 Zealand, and G. C. Davis, of Agricultural College, Michigan, were elected 

 to membership. 



Mr. Osborn presented a paper entitled " Methods of Treating Insects 

 affecting Grasses and Forage Plants." In this paper he considered the 

 insects affecting these crops by groups arranged according to the 

 method of treatment, discussing particularly climatic conditions, natural 

 enemies, agricultural methods and the direct method. He presented a 

 most interesting table of insects, showing in horizontal columns the food- 

 plants, number of annual broods, and the condition in which the species 

 is to be found during any month in the year. The paper was discussed 

 by Mr. Hopkins. 



The next paper, by Mr. Howard, was entitled " Notes on Methods of 

 studying Life-histories of Injurious Insects," in which he described the 

 vivarium methods in use in the Division of Entomology of the U. S. De- 

 partment of Agriculture, but insisted that outdoor work is preferable 

 where feasible. The question of methods of ventilation of the insectary 

 and kindred topics were discussed by Messrs. Forbes, Garman and How- 

 ard. Mr. Forbes thought that indoor work on life-histories should always 

 be verified by outdoor observation. 



Under the caption "Another Mosquito Experiment," Mr. Howard de- 

 tailed his experience with the use of kerosene on the surface of mosquito
