Published online by Cambridge University Press: 31 May 2012
Abstract
Two chalcidoid species, previously known only from Europe, are reported from North America for the first time. Habritys brevicornis (Ratz.) occurs in Quebec, Ontario, and British Columbia. Psilonotus achaeus Wlk. (= Eutelus betulae Grit., new syn.) occurs in Ontario, New York, and Michigan; it parasitizes Oligotrophus betulae Winn. (Cecidomyiidae) in seed of white birch.
