DEPIER OF TiN Shier 
U.S. DEPARTMENT OF AGRICULTURE, 
DIVISION OF ENTOMOLOGY, 
Washington, D. C., October 2, 1899. 
Str: I have the honor to transmit herewith the manuscript of the 
proceedings of the eleventh annual meeting of the Association of 
Economic Entomologists, which was held at Columbus, Ohio, August 
18 and 19,1899. From the fact that the papers presented at the meet- 
ings of this association are always of the greatest economic impor- 
tance, the Department has hitherto published the secretary’s reports 
as bulletins of this division. I therefore recommend the publication of 
the present report as Bulletin No. 20, new series. 
Respectfully, 
L. O. HOWARD, 
Entomologist. 
Hon. JAMES WILSON, 
Secretary of Agriculture.
