LETTER OF TRANSMITTAL. 
United States Departi^ient of Agriculture, 
Bureau of Ektomology, 
Washington^ D. C.^ Fehruary 6^ 1905. 
Sir: I have the honor to transmit herewith for publication a full 
account of the bollworm, prepared under my direction by Messrs. 
A. L. Quaintance and C. T. Brues, special field agents of this Bureau. 
Mr. Quaintance has been engaged for two years in in^ '^stigating the 
work of this very important and injurious insect, hib ork having 
been done mostly in the State of Texas. Mr. Brues as ced him for 
the larger part of the year 1901. The report is a very careful and 
complete account of the bollworm, which, although it has previoush' 
been written about by many entomologists, has never before received 
such a full consideration, and I recommend its publication as Bulletin 
No. 50 of this Bureau. The illustrations submitted are an essential 
part of the report. 
Respectfully, : 
L. O. Howard, 
Entuniologist. 
Hon. James Wilson, 
Secretary of Agriculture.
