bugs in West Virginia this year." 
A, C. Lewis (June 7). "The wheat is now being cut, and to date ^ve have 
not received any complaint of these insects. So far as Tie inoT7 they 
are not present in Georgia. 
H. A- Gossard {June 15) . "As far as our present records go the chinch 
hug is only present in serious numbers in the northvvestem comer of 
the State, northwest of a line running diagonally from the southwestern 
to the north-central botindaries of Paulding County, across the center 
of Defiance County, thence including all of T/illiems County with the 
exception of the southeastern comer, to the north-central part of 
Poulton County, affecting, in all, four counties.

in Paulding County and Van Wert County. I have not yet heard from 
Defiance and Williams Counties farther to the north," 
J. J, Davis (June 10). "The chinch bug continues to loom up as a pest 
of great importance. Wheat harvest began in the southern end of Indi- 
ana on this date. Bugs are abundant in all sections previously reported."

pest this summer."

Saline County."

have been killed. In a few cases in the southern half of the State 
entire fields of 10 to 15 acres of oats have been destroyed. Young 
chinch bugs observed mainly in the second and third instars. Many corn- 
fields in the infested areas are severely damaged where volunteer wheat 
was plowed for com. Creosote barriers being used generally." (J^me 18)
