LETTER OF TRANSMITTAL. 



United States Department of Agriculture. 



Division of Entomology. 

 Washington, D. ('.. March 0S, 1903. 

 Sir: I have the honor to transmit herewith the manuscript of the 

 Proceedings of the Fifteenth Annual Meeting of the Association of 

 Economic Entomologists, which was held at Washington. D. C. . Decem- 

 ber 26 and 27, 1902. The papers presented at this meeting are of an 

 unusually practical nature, and the discussions bring out facts of con- 

 siderable importance. I therefore recommend the publication of this 

 report of the Proceedings as Bulletin No. 40 (new series). 



The term "new series." applied to these bulletins, will be omitted 

 after this number, as it is no longer necessary to distinguish them 

 from the bulletins of the old series, which included only 33 numbers. 

 Respectfully. 



L. O. Howard. Entomologist. 

 Hon. James Wilson. 



Secretary of Agricidturt ■
