description: 2. Zaischnopsis usingeri, new species. Female: 2.5 mm. long, metallic blue-green, the legs fuscous to the tarsi which are pale yellow, the coxae and antennae metallic green, antennae fuscous outwardly, hind femora golden-yellow at base. Mostly smooth and shining, fine pin-point punctuation on head, scutellum shagreened and dull; patches of short appressed silvery hairs on the face and episternae in front, on the axillae and hind coxae, also on underside of abdomen. Head semiglobular, the eyes large oval, reaching top of head above, and below three fourths the distance to base of mandibles, the inner margins diverging anteriorly, the outer curved and forming lateral margin of head; frontovertex small, just large enough to enclose the ocelli, which are arranged in the form of an equilateral triangle, the lateral members placed close to the eye margin; face narrow above, widening below to three to four times its upper width and occupied largely by the antenna! scrobes, which are deeply excavate; below, a triangular flat-topped ridge lies between basal third of the scapes; genae and occiput fairly wide and convex, a distinct carina separating the genae from the face; antennae long (reaching apical margin of thorax), slender, geniculate, attached to lower face not far from mouth opening and rather widely separated at base, 13-jointed, the scapes long, slender, curved, and somewhat flattened (concave inner side, convex outer), the flagellum slender, filiform, widening somewhat outwardly, the distal three segments comprising the club flattened to some extent; mandibles fairly long and stout, apically toothed. Thorax several times longer than wide, somewhat flat, prothorax longer than wide and narrowed apically to a slender neck, the dorsal surface longitudinally furrowed down the middle; mesonotum slightly convex on the sides, sunken in the center behind a triangular boss and between two sharp longitudinal ridges; scutellum scutate, apically rounded and declivous behind, hardly convex, rather flat and bearing on the disk an extensive brush of short, stiff, erect black hairs posteriorly; axillae small, triangular flat sclerites lying in longitudinal rather than transverse direction with saw-toothed basal margin and widely separated so that the inner angles are far apart; episternum elongate, convex; metanotum and propodeum depressed, conspicuously elevated and convex at the posterior lateral angle. Abdomen shorter than thorax, oval, depressed, ovipositor extruded but slightly. Forewings three times as long as greatest width, spatulate, marginal and submarginal veins nearly of equal length, postmarginal longer than stigmal, which diverges from the costal margin at 15-degree angle beyond middle of wing; marginal and discal ciliation short, fine, and complete; a large part of the wing infumate, only the apical fourth and a triangular area behind stigma hyaline. Legs fairly stout, femora and tibiae compressed or flattened to some extent. Piti, Oct. 5, reared from eggs of a katydid, holotype and two paratypes, all females, Swezey.
