Century Dictionary and Cyclopedia
- A large and important order of the class Insecta. The order is characterized by the 4 membranous wings, of which the hind pair is almost always smaller than the front pair, and has comparatively few nervures. The mouth bears mandibles, and a lower lip or tongue sheathed by the maxillæ. The tarsi are generally 5-jointed, sometimes 4-jointed, rarely 3-jointed, and very seldom heteromerous. The abdomen of the female is provided with a multivalve ovipositor, which may act as a sting, a saw, or a borer. The larvæ are vermiform and footless, except in Phyllophaga and Xylophaga, in which they are caterpillar-like and have feet. The Hymenoptera are usually placed at the head of the class of insects, not only on account of their high structural development, but also with regard to their extraordinary instinctive faculties and social qualities. In modern systems the order is divided into 8 series and 36 families. The series are: Phyllophaga, the saw-flies; Xylophaga, the horntails; Parasitica, with six families, the species of which are mainly parasitic; Tubulifera, or cuckoo-bees; Heterogyna, the four families of ants; Fossores, eleven families of sand- and wood-wasps; Diploptera, with two families of solitary and one of social wasps; and Anthophila, with the two families of bees. In number of species this order stands next to Coleoptera; it probably includes nearly one fourth of all insects. More than 1,000 genera are represented in Europe alone, and there are over 7,000 described European species. Between 5,000 and 6,000 species have been described for America north of Mexico, and yet the extensive group of Parasitica is little known, especially in its smaller forms.
