Halstead California State University Fresno, Fresno, California 93740. Present address: HOW, Barstow #112, Fresno, California 93704, Abstract.— The genus Hockeria Walker is revised for the Nearctic region. Nine species are recognized; five new species (hainesi. bicolor, brevipennis. micra, and burksi) are de-scribed. Four previously described species, eriensis (Wallace), rubra (Ashmead), teniii-cornis (Girault), and unipunctatipennis (Girault), are diagnosed and discussed. Males of all species are described and allotypes or plesiotypes designated, Hockeria americensis (Girault) is designated a junior synonym of//, unipunctatipennis. A key to the Nearctic species for both males and females is presented. Characters of females and males are illustrated. Biological and distributional information is summarized for each species, Hockeria eriensis and H. bicolor n,sp. are recorded from the Neotropical region. Key Words: Insecta, Hockeria, Chalcididae, revision, new species, Nearctic The worldwide genus Hockeria Walker contains about thirty described species. Walker described Hockeria in 1 834 with H. bispinosa Fabricius, a European species (synonym of //. bifasciata Walker), as the nominal type-species. Major faunal treat-ments of Hockeria include: Japan (Habu 1960, 1962), Europe (Boucek 1951), USSR (Nikolskaya 1952, 1960), the Near East and India (Husain and Agarwal 1982). Husain and Agarwal (1982) presented a key to the world species of Hockeria but none of the Nearctic species were included. The Nearc-tic Hockeria are revised herein for the first time. No taxonomic keys or comprehensive treatments exist for this fauna. The fauna contains nine species, five of which are new-ly described in this paper. Past literature on Nearctic Hockeria is cataloged in Peck (1963), Burks (1979), and DeSantis (1979). Hockeria are small to moderate sized wasps (2 to 10 mm). Females have slender filiform antennae and are entirely black, red or orange, or commonly with a combination of red or orange and black. Males have ro-bust filiform antennae, are usually black with some orange markings, and are more robust than females. The forewing of females is clouded in a specific pattern whereas in males it is usually clear. At present, a generic revision of the American Chalcididae is underway (Bou-cek, pers, comm,); therefore, a generic de-scription oi Hockeria is omitted. However, to facilitate the identification of this genus for the Nearctic region the following char-acters are diagnostic: vertex not produced into horns, hindtibiae truncate distally, two apical hindtibial spurs present (Haltichel-linae); marginal vein on anterior margin of forewing, postmarginal and stigmal veins present (Haltichellini); tergite 1 without ca-rinae; posterior margin of scutellum with-out a median tooth; frontal carina weak, not joining in ocellar area to form an arch.
