LETTER OF TRANSMIHAI. 



U. S. Department of Agriculture, 



Bureau of Entomology, 

 Washington^ D. (?., Decernbet' i, 1906. 

 Sir: 1 have the honor to transmit herewith a short account of the 

 cotton stalk- borer, prepared by Mr. A. C. Morgan, special field 

 agent in this Bureau. Altho this insect apY)ears, as a rule, to attack 

 cotton stalks which are alread}^ injured or diseased, thus causing only 

 slight damage to the crop, Mr. Morgan finds evidence that healthy 

 stalks ma}^ be occasional!}^ attacked. I recommend the publication of 

 the paper as Part VII of Bulletin No. 63 of the Bureau of Entomology. 

 Respectfully, 



L. O. Howard, 

 Entomologist and Chief of Bureau.

Secretary ' of Agriculture.
