This report summarizes the progress made in 1935 i n the distri- 
bution of exotic species of parasites of the European corn "borer, in 
"both the one- and two-gene ration areas,' as a continuation of the 193^" 
program. Except for subordinating other considerations to the efficient 
handling of Inareclata uunctoria Roman,-, the promising European ichneu- 
monid, no change in the 153^ procedure was made. The total releases in 
1935 ?- re presented in tat le 1, and the 'total releases to Decemter 31> 
1935> since the inauguration of parasite activities, are presented in 
table 2. 
In addition to the parasite material imported from Europe through 
the facilities of the Division of Foreign Parasite Introduction, a 
supply of Cremastus flavoorbi talis (Cam.) was made available through the 
cooperation of the Canadian Department of Agriculture, Entomological 
Branch, in continued importations of parasite material from the Orient. 
This species was desired particularly for release in more southern sec- 
tions now infested "by the "borer. 
~^D. W« Jones, C. A. Clark, and E, D. Burgess assisted in the 
release of the parasites in the regions of their respective assignments,
