of this species in the United States. This species was previously colonized 
in Lucas and Henry Counties, Ohio, and releases were made in 1935 in Hartford 
and New Haven Counties, Conn., Suffolk County, IT. Y. , Monmouth County, N. J., 
a.nd Ac comae County, Va.

It was anticipated that practically all adults of C. f lavoorbitalis , 
estimated to become available for colonization, would be forwarded to 
Belleville, Ontario, for release in Canada.. Therefore, emergence was 
planned to synchronize with the development of the one-generation strain. 
However, emergence greatly exceeded expectation, permitting a number of re- 
leases to be made in the more southern districts of the infested area/ in 
the United States,, While optimum synchronization was not accomplished, it 
is hoped that sufficient contact was made to furnish an estimate of the pos- 
sibilities of this species in the respective environments. Chart 10 shows 
thi s synchroni zation. 
Miscellaneous species : 
Seven adults of the oriental braconid Brae on atricornis Smith were re- 
leased on August lH at the test point in East Hartford Township, Hartford 
County, Conn. 
Conclusions : 
The se?son of 1935 » in general, is considered to have been much more 
favorable for the colonization of parasites than that of 193^ > because of 
less prolonged periods of dry, hot weather. The maps accompanying this re- 
port show that colonies of the tachinid Lydell a stabulans var. grisescens . 
more or less widely spaced, have been placed over practically the entire 
area carrying corn borer populations of sufficient density to be considered 
capable of enabling the parasite to be successfully established. 
In the case of the ichneumonid- Inareolata p unctoria while consid- 
erably less territory has been colonized, with the completion of the current 
season's releases, these colonies have been extended to the more lightly 
infested areas.
