LliTTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Division of Entomology, 

 Was/iingto7i, D. O., February '2 1^.^ 1901/. 

 Sir: I haA^e the honor to transmit herewith the manuscript of a 

 bulletin which contains several articles and notes similar in nature to 

 those which have been presented in previous years under the title, 

 "Some miscellaneous results of the work of the Division of Entomol- 

 og3%" and recommend that the material here presented be published 

 as Part VII of that series. The introductory article on aphides ati'ect- 

 ing grains and grasses is of special value to the economic entomologist, 

 as the identit}' of many of these species has been in a state of confusion 

 for a number of years, and the descriptions here furnished, together 

 with the illustrations, will assist materiall}^ in simplif3dng this matter. 

 For many years there has been great demand for a publication cover- 

 ing the subject of the weevils which affect chestnut, as also pecan and 

 hickory, and the article presented on this subject will, in part, fill this 

 want. The remaining articles are mostl}^ shorter, and each has its 

 special value. 



Respectfully, L. O. Howard, 



EntoDtologiat. 

 Hon. James Wilson, 



Secretary of Agriculture.
