BRUES Eavebelet So hk hep BY Tf BE SRORG el Ee hays DHE ZOOWOGICAL PARK NEW YORK DECEMBER 24, 1921 Volume III, Number 9 A NEW BLEPYRUS By ©. Ts BRUES Blepyrus tachigalie sp. nov. Female. Length 1. mm. Head metallic green, thorax black with an eneous cast, abdomen bronzed black; antennze vellow and black, the scape and funicle yellow, darker on the scape basally, the pedicel and club black; coxe black, femora black with brown tips, tibize brownish yellow with a black streak at base, tarsi pale, with the last joint dark. Wings deeply infuscated basally, hyaline on apical half. Front one- fourth the width of the head at middle, broader above and below, with large punctures forming about four vertical rows; malar furrow shallow and not very distinct; cheeks finely, ver- tically aciculated, eyes with short pubescence. Antenne inserted close to the mouth, the scape reaching barely halfway to the vertex, excavated and distinctly, although not broadly, produced below; pedicel triangular, longer than thick and half as long as the funicle; funicle joints about equal in length, the apical joint more than twice as broad as the basal one; club enlarged, flattened and obliquely truncate at apex, as long as the pedicel and funicle together. Thorax, including scutellum, highly convex when seen in profile, the mesonotum nearly as long as the scutellum, the surface of both shining, minutely punctulate and finely hairy; axillary suture apparently obsolete; scutellum very long, the side margins straight till near the apex, which is therefore rather sharply rounded. Abdomen very short, concave above, with long, scattered hairs at the sides. Legs stout, the spur of middle tibia strong, as long as the first tarsal joint, the tarsal spinules strong on all four basal joints. Mar- ginal vein short, not over twice as long as thick; stigmal vein long, postmarginal slightly shorter, their angle of separation about 100 deg.; wing cilia short, those on the costa longer. 230 Zoologica: N. Y. Zoological Society [III ;9 Type and paratype bred from Pseudococcus bromelix Bouché, occurring in cavities in the petioles of Tachigalia sp. at Kartabo, British Guiana. This species agrees well with Howard’s original generic diagnosis’ except that the antennal scape is slightly enlarged below as in certain species of Bothriothorax (e. g., B. minor Silvestri). The color of the body, appendages and wings will - distinguish the present form. *Proc. U. S. Nat.
