Further observations have been made upon the hibernation of Anopheles quadrimaculatus in Southern Louisiana. Adult females congregate in vast numbers in a deserted fort late in November. The majority of these appear to remain here for a period exceeding two months and then dispersion occurs. No distinguishing characters of the egg, larvae or adults have ever been found and it is therefore again concluded that this does not represent a separate subspecies.
