The report of the Committee on Testing Proprietary Insecticides 

 was presented by Mr. E. D. Sanderson. 



Mr. Sanderson stated that the main work that had been done by the com- 

 mittee had been an effort to secure a national insecticide law and that the 

 progress in that direction had been reported in the last issue of the Journal 

 OF Economic Entomology. The prospects of the passage of such a law are 

 very good and the matter will be taken up at the present session of Congress. 

 He requested the support of the members in furthering this legislation. 



Voted that the report be accepted and the committee continued. 



]Mr. Myron H. Swenk reported for Mr. Laurence Bruner, chairman 

 of the Committee on AlSliation, that some progress had been made in 

 this work, but that no further report could be submitted at this time. 



By vote of the Association, the report was accepted as a report of 

 progress, and the committee continued. 



The President introduced Dr. C. W. Stiles of the United States 

 Marine Hospital Service, who stated that he wished to call the atten- 

 tion of the Association to a movement which was being made to secure 

 greater permanency for insect nomenclature. He stated that the 

 matter was to be considered at the next meeting of the International 

 Zoological Congress, next summer, and for the purpose of securing a 

 list of accepted binominal names to submit to that meeting, he 

 requested that as many zoologists as possible forward to him a list 

 of names which they considered authentic. These names are desired 

 within the next three months, so that they can be edited, and from 

 them a list will be selected for submittal to the meeting next summer. 



The idea of this movement is to secure more stability in the nomen-
