Book Description
Parasitic wasps of the genus Scelio (Hymenoptera: Platygastri-dae) attack and destroy the eggs of short-horned grasshoppers (Acrididae). Included among these hosts are some of the most destructive of all insects, the plague locusts. As a result, species of Scelio are potential allies in the biological control of these pests. This paper is the first comprehensive examination of the species of Scelio of the Afrotropical region in over 50 years. A total of 62 species were found, 77% of which are new to science. Descriptions and keys for identification are provided, and each species is extensively illustrated. This work is a product of the Platygastroidea Planetary Biodiversity Program and was conducted using biodiversity informatics tools and applications developed as part of that project.

Book Description
The United States National Museum contains the types of 735 species of Proctotrupoidea distributed among the various families. The specimens are kept in separate cabinets apart from the regular collection in order to lessen exposure and damage. They are in individual trays in drawers, each tray labeled with the original name, generic and specific, under which the species are descirbed. The collection is grouped by authors; under the individual authors the types are arranged alphabetically by species, and the original or present generic name is ignored. This arrangement assures quick locations of any type contained in the collection.
