LETFER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Bureau of Entomology, 

 Washington, D. C, July 20, 1907. 

 Sir : I have the honor to transmit herewith the manuscripts of the 

 proceedings of the nineteenth annual meeting of the Association of 

 Economic Entomologists, held at New York, N. Y., December 28 and 

 29, 1906. This association, made up largely of entomologists con- 

 nected with the State experiment stations, the Bureau of Entomology 

 of this Department, and others engaged officially in entomological 

 work, is an important one, and the proceedings of its annual meet- 

 ings contain papers and discussions on injurious and beneficial 

 insects which should by all means be put in print. I therefore rec- 

 onnnend that, following the custom of previous years, the proceed- 

 ings of this meeting be published as Bulletin No. GT of this Bureau. 

 The two plates and six text figures are necessary for proper illustra- 

 tion of the text. 



Respectfully, L. O. Howard, 



Entomologist and Chief of Bureaa. 

 Hon. James Wilson, 



Secretary of Agricidture.
