7. Ooencyrtus swezeyi , new species.

Females: 0.7 mm. long, cadmium yellow to fuscous on head and thorax, but with stutellum dark metallic green, metanotum and pleurae, also apical segments of abdomen, eyes, antennae, and hind tibiae black or blackish.

Body compact, head not decidedly lenticular but somewhat so in outline when viewed from above; seen from the side, the outline is that of an isosceles triangle with the line of the front and face forming the two short sides. Eyes lateral, short oval in shape, large, convex; frontovertex more than twice as long as wide (shorter and wider in male) with the ocelli in the vertical end arranged in an equilateral triangle; front half punctuate along the eye margins, the punctuations fine pin-point punctures bearing short black hairs; front not meeting face abruptly but the two planes merging gradually in a wellrounded junction; face widening considerably in the direction of the mouth, the antenna! scrobes rather broad and shallow. Antennae fairly long and stout, nearly as long as the thorax, scape long and slender, somewhat fusiform, reaching a little beyond the upper limit of face, pedicel obconic, more than twice as long as the apical width, twice as long as any of the six funicle joints, which are separately a little longer than wide, club as long as the last three funicle joints, entire funicle cylindrical, the club a little stouter, all the joints clothed with black hairs (individual joints flecked with white in some specimens). Pronotum declivous, separated from mesonotum by a distinct carina which is transverse, three times as wide as long, smooth and shining but uniformly punctuate, the fine pin-point punctuations bearing short black hairs; scutellum rather large, convex, nearly as long and as wide at base as mesoscutum, scutiform, with shagreened surface and fine pin-point punctuations seating short black hairs as in mesonotum; axillae small, narrow, not meeting medially; metanotum and pleurae smooth and shining. Abdomen small, shorter by one half than the thorax, triangular in shape, depressed; ovipositor scarcely extruded. vVings hyaline, marginal vein punctiform, not much longer than wide, stigmal vein a little longer than postmarginal, expanded some at apex and hooked or clawed, longer than the body and about one third as wide, long ovate in shape with the posterior margin straight from beyond middle to base; discal ciliation fine and close to speculum, which widens posteriorly; basally beyond the speculum the ciliation is not so close and fine and extends only half way to base of wing where the wing is quite bare; submarginal vein bearing seven or eight fairly long and stout hairs; marginal ciliation short and close. Legs moderately long and stout, generally concolorous with body.
