REVIVAL OF Lepidoptera
This Danish journal, organ of the Lepidopterologisk Forening in Copenhagen, was published from 1946 to 1951. The first issue of Volume 1 of a new series has now appeared, and includes, among other notes, the first part of a series describing and figuring the Danish Eupithecia. One or two issues a year are planned. The editor is T. W. Langer. For subscriptions write the Honorary Secretary, Johs. Storm-Olsen, R0dkildevej 14, Copenhagen F., Denmark.—P. F. Bellinger
