LETTER OF TRANSMITTAL. 
U. S. Department of Agriculture, 
Bureau of Entomology, 
WasJiington, D. C, January 2, 1912. 
Sir: I have the honor to transmit herewith, for pubUcation as 
Bulletin No. 112 of this bureau, the manuscript of a prehminary 
report on the investigation of the alfalfa weevil in Utah and adjacent 
States. The investigations of the Bureau of Entomology in coopera- 
tion with the Utah Agricultural Experiment Station began April 1, 
1910, and still continue. The period covered by this report is 'from 
April 1, 1910, to November 15, 1911. From April 1, 1910, to April 
1, 1911, the bureau was represented in the investigations with but one 
assistant. Since that time the force has been increased until eight or 
nine persons have been from time to time employed. The information 
given is exactly what the title of the bulletin imphes, prehminary in 
nature and not to be taken as conclusive in all cases. It is simply a 
short account of what has been done within the period of time just 
indicated. 
Respectfully, L. O. Howard, 
Entomologist and Chief of Bureau. 
Hon. James Wilson, 
Secretary of Agriculture.
