THEODORE G. ANDREADIS

The Connecticut Agricultural Experiment Station, 123 Huntington Street, PO Box 11O6, New Haven, CT O65O4

ABSTRACT. Distribution and collection records for 3 previously unrecognized species, Anopheles barberi, Culex erraticus, and Ochlerotatus diantaeus, are included herein. This brings to 48 the number of recognized species from I 1 genera in Connecticut. Also, an updated checklist of the mosquitoes of Connecticut that reflects the recent elevation of the subgenus Ochlerotatus to generic rank is presented.
