LETTER OF TRANSMITTAL. 
U. S. DEPARTMENT OF AGRICULTURE, 
DIVISION OF ENTOMOLOGY, 
Washington, D. C., June 15, 1898. 
Srr: I have the honor to transmit herewith a Farmers’ Bulletin on the peach 
twig-borer, an important enemy of stone fruits. It has been prepared by my first 
assistant, Mr. C. L. Marlatt, and consists in the main of a revision of an article pub- 
lished in Bulletin No. 10, new series, of this Division. It is issued in its present 
form to supply a demand for a larger circulation of the information contained in the 
article cited, particularly in California and elsewhere on the Pacific slope, wher 
the twig-borer is especially abundant and destructive. 
Respectfully, 
L. O. Howarp, Entomologist. 
Hon. JAMES WILSON, 
Secretary of Agriculture.
