Adult. — Length of forewing, 6 mm. Color grey, legs pale brownish. Abdomen without sternal processes. Male genitaha: Ninth sternum large, posterior margin obliciuely angulate laterally, with a smooth, impressed midventral line. Ninth tergum smooth, small, rounded anteriorly; with a bandlike lateral sclerite con-tinuous along dorsal margin of sternum. Tenth tergite a long, swordlike process directed posteriorly beneath lobes of aedeagus. Claspers small, with an apico-ventral point, and a terete, membranous lateral lobe; mesoventrally with a structure, trianguloid in ventral aspect, complex internally. Aedeagus with a tubular basal portion; apex developed into a pair of crenulate, membranous, hemispherical lobes which give rise to a basolateral process curving beneath lobes and becoming heavily sclerotized apically, apicomesally with a rounded, membranous lobe ( apical structures do not seem to be retractable within tubular portion ) .

WEST INDIAN WASPS OF THE SUBFAMILY PRISTOCERINAE ( Hymen OPTERA : Bethylidae ) Howard E. Evans, Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 02138 ABSTRACT — Three genera of Pristocerinae occur in the West Indies, but all three have been known from only a few specimens. Much recently collected material from Cuba and from Jamaica indicates that there are several species of Pristocerinae on each island, with no species reported from any two islands of the Greater Antilles. Female Pristocerinae are apterous, and hence have poor dispersal powers as compared to Epyrinae and Bethylinae, several species of which occur widely in the West Indies. In the genus Fseudisohrachiuvx, previously unrecorded from Cuba and Jamaica, 11 new species are here described, 3 from Cuba and 8 from Jamaica. In Apenesia, 4 new species are here described, 3 from Jamaica and 1 from Cuba, and new records are presented for a previously described species. In Dissomphalus 1 new species is described from Jamaica and 1 from Cuba. In my Synopsis of the American Bethylidae (Evans, 1964) I re-corded 33 species of Bethylidae from the West Indies (not including Trinidad). In a recent paper (Evans, 1969), I have reported 19 species from the island of Dominica alone, 13 of them previously
