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

 Proceedings of the Seventeenth Annual Meeting of the Association of 

 Economic Entomologists, which was held at Philadelphia, Pa., De- 

 cember 29 and 30, lOOi. As the papers presented at the meetings 

 of this association are of very considerable economic importance, 

 and as the Department of Agriculture has hitherto published the 

 reports of the secretaries of these meetings as bulletins, I recommend 

 the publication of the present report as bulletin Xo. 5'2 of this Bureau. 

 The text figures are necessary for the illustration of the text. 

 Respectfully, L. O. Hoavard, 



Entomolught and Chief of Bureau.
