THE Ministry of Food has published, under the title of "Insect Pests of Food" (London: H.M. Stationery Office, 5s. net), two important papers on moths and their larvæ affecting stored products. They are designed to provide a reliable and up-to-date guide to the identification of the insects referred to. Although the two papers are primarily for the use of the Ministry's inspectors, they will be valuable to anyone concerned with the pests in question. The paper on lepidopterous larvæ affecting stored products is by Dr. H. E. Hinton and was originally published in the Bulletin of Entomological Research (34), and that on the moths by Dr. A. S. Corbett and Mr. W. H. T. Tarns is reprinted from the Proceedings of the Zoological Society of London (113 B).
