Abstract
THE economic importance of the Coccidas (“mealy bugs” and scale-insects) is very great, especially in warm countries. It is satisfactory to see, therefore, the first part of an extensive monograph on the Coccidæ of South Africa, by C. K. brain, published as part 2 of vol. v. of the Transactions Royal Soc. S. Africa (Cape Town, 1915). This contains a general introduction to the study of the family and detailed descriptions of the genera and species of the Pseudococcinæ, Ortheziinæ, Coccinæ, Monophlebinæ, and Margarodinæ. The systematic work has1 been done with great care, a notable feature being the charts demonstrating in the case of each species the range of variation in the lengths of the antennal segments; the illustrations—photographs and drawings—fill thirteen plates. The author has spared no pains to enlighten his readers, but it was scarcely necessary to include in his glossary the information that “ovum” means “an egg,” and “transparent,” “so clear as not to obstruct vision.”
