THE FAMILY EUCHARIDAE — GAHAK 451 



ORASEMA ROBERTSONI, new species 



Similar to viridis Aslimead but differs by having the femora all 

 testaceous instead of green, the head and thorax dark green instead 

 of bright green, and the mesepimeron completely sculptured instead 

 of smooth on its upper half. 



Female.— Length 3.25 mm. Dark olive-green, the mesoscutum and 

 scutellum dorsally faintly aeneous; antennal scape and legs, except 

 coxae, testaceous, the scape and femora slightly washed with metallic ; 

 pedicel and flagellum brownish black; coxae and abdominal petiole 

 concolorous with thorax; gaster metallic green; wings hyaline. 

 Head, thorax, propodeum, coxae outwardly, abdominal petiole, and 

 the second sternite with nearly uniform fine alveolate punctation; 

 gaster mostly polished. Antennal scape cylindrical, reaching to level 

 of lower margin of front ocellus ; pedicel a little longer than broad ; 

 flagellum a little thicker than pedicel, not at all clavate; ring joint 

 very small and inconspicuous; first funicle joint not quite twice as 

 long as broad, following joints successively diminishing slightly in 

 length, the seventh joint subquadrate; club very slightly longer than 

 two preceding joints. Head as wide as thorax, slightly concave 

 behind ; ocelli in a low triangle ; postocellar line slightly longer than 

 ocellocular ; lateral ocellus a little more than twice its own diameter 

 from eye margin; antennal scrobe shallow; malar space very nearly 

 as long as eye, slightly flattened or very weakly depressed for its 

 whole length ; clypeus uniformly sculptured but a little less strongly 

 so than the rest of face, about as long as wide at apex, its anterior 

 margin nearly straight; supraclypeal area defined laterally by deep 

 grooves but not distinctly separated from clypeus, the usual suture 

 connecting the clypeal fovea nearly obsolete. Parapsidal grooves deep 

 and weakly foveated; scutellum high, convexly rounded dorsally, 

 weakly margined low down on the sides and with a deep transverse 

 groove before the apex ; propodeum with deep and coarsely foveated 

 spiracular sulci and with some small foveae along the basal margin 

 but without lateral folds or median carina. Legs normal. Forewing 

 weakly ciliated, bare basally, the costal cell very nearly or quite bare ; 

 marginal vein more than half as long as submarginal ; postmarginal 

 vein about one-third as long as marginal, stigmal vein short and 

 slightly oblique. Abdominal petiole as long as hind coxa, about twice 

 as long as broad ; gaster a little smaller than thorax, its base beneath 

 (second sternite) sculptured like the petiole and the two apical 

 tergites very weakly shagreened, the rest smooth and polished; ovi- 

 positor not exserted.
