A Note on the Parasitisation of the Oöthecae of Periplaneta americana (L.) by the Chalcid, Syntomosphyrum glossinae Wtstn. —a Correction

Abstract

A correction is made to a paper by Nash (1955) in which Syntomosphyrum glossinae Wtstn., a Chalcid parasite of the pupae of tsetse flies, was wrongly recorded as parasitising the oöthecae of Periplaneta americana (L.). The parasite in question was almost certainly the very similar Tetrastichua hagenowii (Ratz.)which is a world-wide parasite of P. americana. There is no evidence that eitherparasite can attack both P. americana and Glossina palpalis (R.-D.).
