LETTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Division of Entomology, 

 Washington, D. C, July 20, 1896. 

 Sir : I liave the honor to transmit herewith the manuscript of a 

 General Index to Insect Life, the periodical bulletin of this Division, 

 seven volumes of which were published between July, 1888, and 

 July, 1895. Each volume as published contained an index, but there 

 has been a decided demand from working entomologists for a com- 

 bination index to the seven volumes. The very great number of short 

 articles and notes of general interest to which entomologists have 

 frequently to refer renders this comprehensive index most desirable, 

 and in response to this demand it has been prepared. I respect- 

 fully recommend that it lie printed as an unnumbered j^nil )Iication 



of this Di^asion. 



Respectfully, 



L. O. Howard, 



Entomologist. 



Hon. J. Sterling Morton, 



Secretary of Agriculture.
