Abstract
THE theory of phase variation in swarming locusts was first put forward about ten years ago, since when a considerable amount of data has been accumulated in its support. Most of the evidence, however, was either based on direct field observations, or on small-scale experiments which served only to prove the fact of the trans formation from the solitary to the gregarious phase, and vice versa, but were insufficient for analytical study of the phenomenon and of its underlying causes. This gap has now been filled by a paper by Prof. J. C. Faure recording the results of four years' experimental studies on the phases of four species of locusts occurring in South Africa.*
