Abstract
In 1955 and 1956, while sampling corn stalks for larvae of the European corn borer in experimental plots at St. Jean, the author noted 23 adults ofColeomegilla maculata lengiTimb. and two adults ofCoccinella novemnotataHbst. that were parasitized and attached to the upper surfaces of corn leaves. Each beetle was astride a freshly formed cocoon and was held by a network of silk; many were alive when found. The parasite cocoons and the hosts were placed in closed petri dishesfor observation. The parasites that emerged were identified by Dr. W. R. M. Mason, Entomology Division, Ottawa,asPerilitus coccinellae(Schrank) (=Dinocampus terminatus(Nees).Keywords
