PRODENIA LITTORALIS.
A moth, expanding about one inch and a half, found in Africa, but not in England. It has brown-grey fore-wings, with opalescent markings. The hind-wings are of a shining opalescent white. The larva is brown, feeds on the potato-plant, and appears during the early spring. The moths are seen a month or six weeks later; those bred in captivity appear simultaneously with those out of doors.
