able to secure a large number of gravid females of Anopheles quadri- 
maculatus Say through the abundance of this species near the home of 
one of his assistants, Mr. Pratt, in Virginia, a few miles from Wash-

adults, and these were kept in confinement and their offspring reared 
in large water jars during Apriland May, 1900. It may be mentioned 
here that this species is without doubt identical with the European

he has studied a large series of A. quadrimaculatus received from 
Canada and that ‘‘they exactly tally with A. maculipennis.”
