A new species of Perniphora Ruschka reared in Maine, U.S.A., and New Brunswick, Canada, from logs of white and yellow birch infested with ambrosia beetles, especially Trypodendron betulae Swaine, is described and illustrated. It is compared with the only other described species, Perniphora robusta Ruschka, a Palearctic species which has been reared, according to Ruschka (1923), Novak (1960a, b), Balazy (1963) and Hedqvist (1963), from a number of ambrosia beetles, especially Trypodendron lineatum Oliv., in Germany, White Russia, Czechoslovakia, Poland, Denmark, Finland and Sweden.
