and one of 595) were released in Tfoodland Township, Burlington County, IT. J., 
on June 17 and July 18, respectively, supplementing the 1935 releases in 
that locality. 
C. annu lipes (B raconid ae) . — Through cooperation with the Entomological 
Branch of the Canadian Department of Agriculture it was possible to release 
three lots of this species at one colony site in Lee Township, Accomac County, 
Va. These releases consisted of individuals "bred in the laboratory at Belle- 
ville, Ontario, and were made on July 31, August 7, and August 19. A total of 
2,105 adults were released in lots of 873, 1,008, and 224, respectively, on 
the above dates. It is known that host eggs, the stage utilized by this spe- 
cies for oviposition, were present in the field during the period of release. 
Co nclusions • — Except in Virginia and western and central Ohio, where 
the weather was abnormally hot and dry, the season in general appeared favor- 
able to the successful colonization of corn borer parasites. The completion 
of the current season's colonization activities has demonstrated that Inareo - 
lata punctoria , one of the most promising of the imported parasites of the 
corn borer, may be obtained in satisfactory numbers more economically from 
well-established colony sites in the United Sta.tes than from foreign sources.
