 Division of Entomology, 
 Washington, D. C, July 10, 1902. 
 Sir: I have the honor to transmit herewith manuscript of an index 
 to the Bulletins of the Division of Entomology, Nos. 1 to 30, new series, 
 published in the years 1896 to 1901, and which has been prepared by 
 Mr. Nathan Banks, an assistant in this office. These Bulletins are con- 
 stantly referred to by experiment-station entomologists and others 
 interested in this subject, and we have frequently received letters ask- 
 ing that such a general index be published. I therefore have no hesita- 
 tion in recommending its publication. 
 Respectfully, 
 
 L. O. Howard, 
 
 Entomologist. 
 Hon. James Wilson, 
 
 Secretary of Agriculture.
