SYNOPSISAn account is given of the direction of flight in night‐flying insects in Kenya with special reference to the influence of wind direction.
S ynopsis The aedeagus of Apis dorsata is described, and compared with that of the other three species of Apis.
SYNOPSISThe immature stages of Rhyssa persuasoria, R. amoena, Megarhyssa emarginatoria, Pseudorhyssa sternata and Odontocolon geniculatus, ichneumonid ectoparasites of European Siricidae, are described and a key based on the last larval instars of these species is included. Their relationships are discussed with reference to the morphology of the intermediate and final instars.
SYNOPSISAn account is given of the life history of Ibalia drewseni, an internal parasite of siricid woodwasps. The immature stages are described, and a key is given for the separation of the adults from those of I. leucospoides. The distribution of the species is discussed.
