Abstract. — Invreia deceptor, /. usta, and /. threa, new species, are de-scribed and keyed based on material reared from lepidopterous pupae col-lected in peanuts. All three new species are known from Texas and attack pupae of Elasmopalpus li^noselliis (Zeller). Invreia deceptor and /. threa are also known from Oklahoma, where deceptor attacks E. Ugnosellus and Stegasta bosqiieella (Chambers), but threa so far is known to parasitize only the latter host. Invreia mirahilis of Wall and Berberet, the only pre-viously reported Invreia in the New World, is a misidentification of decep-tor: I. mirahilis Boucek is a valid Old World species. Invreia mirabiUs Boucek, an Old World species, has thus far been the only member of the genus known from the New World. It was recently reported from Oklahoma by Wall and Berberet (1975) as a parasite of lepi-dopterous pests on peanuts. In studying the Wall and Berberet specimens as well as additional material from Texas, we find that mirahilis is a mis-identification and that three undescribed species are represented. Because several workers are holding manuscripts pending the identification of these specimens, we take this opportunity to describe three new species of In-vreia. Invreia mirahilis is a valid Old World species but is not known to occur in the Western Hemisphere. The most recent revision of Invreia was by Nikolskaya ( 1960) who treat-ed 17 species worldwide. Since that time one species has been described by Steffan {\9^2\ f estiva) and another by Habu (1970: ghanii). Habu also cited taxonomic literature for the genus but overlooked a paper by Erdos (1957) describing the female of /. mirahilis. Additionally Steffan (1976) transferred the previously described species eleganttda Masi from Euchalcidia to In-vreia, making a total of 20 described species worldwide to date. We add
