Extract

At the Lethbridge laboratory, uncut wheat stems infested by the wheat stem sawfly, Cephus cinctus Nort., were collected in August, 1952, and incubated in sealed vials at room temperature for emergence of parasites. In October, 1952, three adult parasites (two females, one male) emerged. These specimens were identified as of Scambus detritus (Holmg.), Ichneumonidae, by Mr. G. S. Walley, Division of Entomology, Ottawa.
