Culex (Culex) torrentium Martini, a mosquito new to Great Britain

Abstract

FOURTH instar larvæ and pupæ referable to Culex (Culex) torrentium Martini were taken in some abundance from water-tanks on allotments at Isleworth, Middlesex, by Mr. Bowles, of the Health Department, on June 19 of this year. They were sent for identification, together with emergent adults, to the British Museum. The name torrentium, is applied provisionally since, as Natvig1 has pointed out, the synonymy of the group is somewhat obscure and requires further investigation. There can, however, be little doubt that this is the Scandinavian species described by Natvig as torrentium. © 1951 Nature Publishing Group.
