U. S. Department ot Agriculture, 
Bureau of Entomology, 
Washington, D. C, August 17, 1911. 
Sir : I have the honor to transmit herewith for publication a manu- 
script entitled " Results of the Artificial Use of the White-Fungus 
Disease in Kansas: With Notes on Approved Methods of Fighting 
Chinch Bugs," by Frederick H. Billings, associate professor of botany 
and bacteriology, and Pressley A. Glenn, assistant professor of ento- 
mology, University of Kansas. 
The chinch-bug situation having become serious in Kansas, pro- 
vision was made by the University of Kansas for the distribution of 
insects infected with the white fungus, Sporotrichum globuliferum. 
The results of this work are embodied in the following pages, and 
I recommend the publication of this manuscript as Bulletin No. 107 
of this bureau. 
Respectfully, C. L. Marlatt, 
Acting Chief of Bureau. 
Hon. James Wilson,
