April, '08] JOURNAL OF ECONOMIC ENTOMOLOGY 159 



Mr. Sanderson described the recent spread of the gypsy moth in 

 New Hampshire, and stated that small colonies, some of only a single 

 egg cluster each, were being found in the hill towns miles from the 

 nearest known infested point. He believed that the only way of 

 accounting for the presence of these colonies is that there is some 

 means of distribution of this insect which at present is unknown. 



This closed the discussion of the papers presented, and the meeting 

 formally adjourned. 



We regret that owing to limitation of space it has been impossible 

 to include in this number all of the papers presented by title or other- 

 wise, at the twentieth meeting of the Association of Economic Ento- 

 mologists. The papers remaining will appear in the next issue. 



STATEMENT BY THE STANDING COMMITTEE ON 

 PROPRIETARY INSECTICIDES 



At the Chicago meeting it was voted (see page 10, Feb. issue,) that 

 all new proprietary insecticides offered to members of this association 

 be referred to this committee, who will then proceed as suggested 

 in the report of the committee on this matter of last year, Part II. 



Your committee has recently received communications from J. W. 

 Lafer, Catawba Island, Ohio, regarding a remedy to be applied to the 

 roots of trees to prevent the attacks of insects and generally stimulate 

 the tree. Mr. Lafer states that some 12 Stations have signified their 

 willingness to test this remedy. Your committee begs to recommend 

 to the entomologists of the association that any tests which may be 

 desired be made after consulting with this committee, so that the 

 number of tests may be reduced in number. It is the judgment of 

 your committee that the testing of this substance is of doubtful expe- 

 diency until the proportions of its ingredients are known. 



Your committee further requests that any new insecticides which 

 are submitted for testing be called to their attention with a statement 

 as to whether the party wishes to make a test of them and any sug- 

 gestions concerning the matter. We believe that in this way the 

 testing of proprietary insecticides can be much simplified. 



As instructed at Chicago, your committee has had prepared, thru 

 the courtesy of the Bureau of Chemistry of the Department of Agri- 

 culture, a National Insecticide Law which will probably be introduced 

 during the present session of Congress. Copies will be furnished 



members of the association as soon as the bill is in print. 



E. DwiGHT Sanderson, 

 Chairman.
