In collection insects of Poquonock, Conn., July 18, 1904, my assistant, Mr. B.H. Walden, found coccinellid larvæ feeding upon a species of Aleyrodes which is probably undescribed, and fairly common there upon the leaves of hazel, Corylus Americanus. These larvæ were brought to the laboratory, and were fed upon Aleyrodes vaporuriorum, Westw., which they ate greedily.
