Collected Records Relating to Insect Migration

Abstract

In continuation of my policy of putting on record the largest possible number of facts relating to insect migration, on which alone can a satisfactory study of the subject be based, I give below a series of new observations that have come to my knowledge since the preparation of my last paper in the Bull. Soc. Roy. Ent. Egypte, 1926 (1927), pp. 224-256. A few of the observations are my own, but the majority have been sent in by correspondents, whom I take this opportunity of thanking.
