In a survey of wood-feeding Anobiidae occurring in the Northeastern United States and adjacent Canada, a species of Ptilinus was found which the author believed to be new and for which the trivial name friendi was proposed (Simeone, 1960). However, having had the opportunity during the summer of 1960 to examine and collect European species at the Forest Products Research Laboratory, Princes Risborough, England and at der Forstliche Bundes-versuchsanstalt Mariabrunn in Schönbrunn, Vienna, Austria, the author now believes his specimens to have been introductions of the common species, Ptilinus pectinicornis L. In view of rhe economic importance of this species in other parts of the world, it seems advisable to describe in some detail the adult male and female as well as to compare some of the characteristics whereby the insect can be distinguished from closely allied species.
