Bureau or ENnromoroey, 
Washington, D. C., March 20, 1905. 
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, 1904. 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 No. 52 of this Bureau. 
The text figures are necessary for the ilustration of the text. 
Respectfully, L. O. Howarp, 
Entomologist and Chief of Bureau. 
Hon. James WILson, 
Secretary of Agriculture.
