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.
