In a recent number of this journal* Mr. Quayle gives some notes on the habits of the Californian Culex squamiger, Coq., and compares these briefly with those of a species occuring in Nw Jersey which we have been calling squamiger (following a determination by Mr. Coquillett), and suggests the possibility of there being two forms. The identification of our species with the Californian one has been doubted by Prof. Smith and myself since we learned of the salt-water habit of the latter; but not until Mr. Quayle pointed out the difference in the length of tracheal gills of the larva was a close comparison of the species made.
