. Entomology for medical officers. Insect pests; Insects as carriers of disease. Fra. 107.—Colorado Beetle, enlarged. FiQ. 108.—C(rfaji*a, much enlarged. Rhynchophora. This enormous suborder includes the true weevils, most of which can be recognised by their long snout: they are mostly wood-borers and plant-eaters, but some are well known as destructive to stored grain— certain species of the genus Calandra (Fig. 108). Order Strepsiptera. (Gr. arpe^ = twisted, and vreptiv = wing.) Minute insects, of which the females are degraded, wingless, and legless endoparasites of certain Hymenoptera

Order Strepsiptera. (Gr. arpe^ = twisted, and vreptiv = wing.) Minute insects, of which the females are degraded, wingless, and legless endoparasites of certain Hymenoptera and Hemiptera. The short-lived males are active and well endowed, possessing large hind wings, which have no cross-veins, and vestigial front wings. The larvae are parasitic in the larvae of their mother's host. The Strepsiptera art now very commonly classed with the beetles {Co/eoptera)..
