LETTER OF TRANSMITTAL. 



U. S. Department' of Agriculture, 



Division of Entomology, 

 Washington, D. C, April®, 1901. 

 Sir: I have the honor to submit herewith manuscript of a paper- 

 entitled Some Insects Injurious to the Violet, Rose, and Other Orna- 

 mental Plants, which has been prepared with admirable care and 

 thoroughness by Mr. F. H. Chittenden, of this Division. The subject 

 is one which has engaged Mr. Chittenden's attention for some time, 

 and the investigation was necessitated by a very general complaint of 

 damages by insects from growers of hothouse plants. The general 

 subject is one which has not heretofore been treated, and the work is 

 unquestionably needed. I recommend its publication as Bulletin No. 

 27, new series, of this Division. 

 Respectfully, 



L. O. Howard, Ento-tnologist. 

 Hon. James Wilson, 



Secretary of Agriculture.
