8. Cheiloneurus chrysopae   , new species.

Female: 1.5 mm. long, golden-yellow with metallic green infuscations on head (cheeks and frontovertex), thorax (mesonotum), and abdomen basally. Antenna! club, eyes and scutellar brush black, legs pallid,. the femora and tibiae slightly fuscous.

Head approaching the hemispherical in shape, viewed from above nearly circular in outline, from the side the outline is that of an obtuse triangle with the line of the occiput forming the long side and that of the face and the frontovertex respectively the two shorter sides, the respective planes of the frontovertex almost at right angles to each other, the former being horizontal and the latter nearly vertical; the eyes are of moderate size, oval, convex, naked; frontovertex elongate, hourglass-shaped, twice as wide in front and behind as in the middle and six times as long as the width there, with its surface coarsely shagreened; ocelli small, the anterior member marking the.point of an acute angle, the lateral members close to the eye margin and not far from the vertex. Face considerably excavated to form the widely separated antenna! scrobes, central field elevated and convex. Antennae attached not far from the mouth opening, generally cylindrical and rather short and stout, consisting of nine segments (scape, pedicel, six funicle joints, and undivided club). Scape long and slender, somewhat fusiform, reaching beyond the upper margin of the face and to lower margin of eye, pedicel obconic, less than one sixth length of scape, funicle joints all transverse and widening outwardly, the sixth twice as wide as the first, all six together shorter in length than the scape, club still wider at mid length, flattened and equal in length to the funicle, all the joints clothed with short silvery pile; cheeks coextensive with the lower part of frontovertex, rather wide and convex, and shagreened; mandibles short, blunt and three-toothed.

Pronotum short, transverse, convex; mesonotum transverse, twice as wide as long, convex, shagreened and heavily clothed with short, appressed, silver-gray hairs; scutellum scutiform, convex, also clothed with longer, coarser hairs which form a brush at apex; axillae triangular, apices touching in middle line; metanotum transverse, declivous.

Abdomen roughly ovate, pointed apically, considerably shorter than the thorax, widest at apical margin of first segment, median segments considerably depressed, sparsely clothed with silvery hairs apically. Ovipositor not projecting beyond tip of abdomen.

Forewings spatulate, three times as long as wide, marginal vein only half as 1long as submarginal, reaching halfway along costal margin, stigma! and postmarginal short, marginal ciliation short outwardly, a little longer on caudal margin basally, eight to ten longer setaceous hairs on submarginal vein, the discal ciliation close and fine, the disk of wing infumate in outer two thirds almost to apical margin with a short clear streak below stigma. Legs fairly long and stout, the spur on median pair as long as metatarsus.

Male: smaller and more dusky, head entirely metallic green, frontovertex wider than in female, wider than eyes but still longer than wide; antennae pallid, filiform, clothed with whorls of long hairs, all the funicle joints twice or more longer than wide, club not enlarged or flattened; wings hyaline, entirely without infumation.

Described from five females and three males (holotype, allotype and paratypes) as follows: holotype female and allotype male mounted on a single point, two more points, each with one male and one female paratype, and one point with two female paratypes, labeled Merizo, June 11, reared from a Chrysopa   cocoon, Swezey. Six other specimens.
