Abstract
The following notes report the occurrence in Nova Scotia ofSthereus ptinoides(Germ.) and indicate the distribution in North America of 35 species introduced there from the Old World. Of the Old World species, ten are reported from America for the first time; previous records of two others are probably erroneous. Two, which were named and described inRhyssemusMuls. andScolytusGeoff. as species native to America, are considered introduced, and new synonymy is proposed for them. Confusion of introduced with native species is noted inStethorusWeise andRhinoncusSchön. The material recorded from Newfoundland was collected in the Northern Insect Survey, which is a co-operative project of the Canada Department of Agriculture and the Defence Research Board, Canada Department of National Defence.
