Dendrosoter protuberans (Nees) was introduced into the United States from France as a possible addition to the existing spectrum of hymenopterous parasites of the smaller European elm bark beetle, Scolytus multistriarus (Marsham). D. protuberans is an external parasite; it oviposits through bark onto or next to late-instar larvae of S. multistriatus (Kennedy 1970) (Fig. 1).
