Leucospis auripyga sp. n. 



(Text-figs 87, 88) 



9. 9-5 mm. Black with moderate metallic tinge, mostly dark violaceous but in places 

 purplish to brighter cupreous or bluish to greenish, apex of gaster mainly golden, broad furrows 

 on first tergite golden-cupreous; pale yellow markings: scapus, narrow band posteriorly on 

 pronotum, very narrow posterior margin of mesoscutum, anterior side of fore tibia, mid knee, 

 narrowly basal edge and apically lateral edge of hind coxa, upper edge and ventro-basal streak 

 of hind femur, hind tibia except at ends ; reddish is callus of propodeum, dorsum of first tergite, 

 partly hind coxa, ovipositor sheaths basally. Antennae beneath and legs also partly reddish. 

 Wings distinctly yellowish brown, darker at anterior margin. Pubescence of body white, 

 short, except apically on gaster where brassy-golden. 



Head as broad as pronotum posteriorly, in dorsal view 2-5 times as broad as long; temples 

 very short but distinct. Vertex punctured except just outside of each ocellus; occipital carina 

 not high and disappearing shortly beyond ocelli; POL sub-equal to OOL; ocelli not small, their 

 triangle 2-4 : 1, between median and lateral ocellus weakly raised; scrobal carina sharp, 

 near to median ocellus; frontal protuberances moderate. In facial view head 1-35 times as 

 broad as high (Text-fig. 88) ; face broad and fairly convex, moderately densely and rather 

 shortly pubescent, interantennal lobe with distinct carina. Relative measurements: width of 

 head 69, height 51, width of frontovertex 40-5, of lower face 38, its height 23, width of scrobes 

 20, eye 36 : 24, its inner orbit moderately emarginate; malar space 11-3, width of mouth 27, 

 length of scape 18. Clypeus hardly broader than high, sub-triangular; lower margin narrowly 

 smooth, with low lobe on each side, emarginate and depressed in middle. Scapus about 3-3 

 times as long as broad. Flagellum slightly clavate, apically i-6 times as broad as pedicellus, 

 latter slightly longer than broad ; flagellum plus pedicellus combined hardly longer than breadth 

 of head ; first flagellar segment slightly longer than pedicellus and slightly shorter than following 

 segment, this slightly elongate; fifth flagellar segment subquadrate, distal ones slightly 

 transverse; clava about 1-7 times as long as broad, apex rounded. 



Thorax densely punctured, narrow interspaces with microscopic cross-reticulation which is 

 obliterated on disc of scutellum. Pubescence dorsally very short, inconspicuous. Pronotum 

 convex, without carinae; hind margin broadly emarginate; sides straight, weakly converging; 

 lateral panel posteriorly, moderately broadly depressed, with short vertical keel separating 

 spiracular emargination ; lower corner rounded, obtuse-angular. Mesoscutum not depressed, 

 regularly punctured ; vestiges of parapsidal furrows hardly as long as their distance from lateral 

 margin. Scutellum (without sloping diverging axillae) 1-2 times as broad as long, fairly 

 convex, admarginal row of punctures posteriorly hardly impressed. Dorsellum bare, alveolate, 

 semicircularly margined with high carina, fully 3 times as broad as long; sides of metanotum 

 with a row of coarse foveae. Propodeum in middle elevated and slightly longer than dorsellum, 

 median carina sharp and fairly high, arched, hairs at carina pointing mainly laterad as in all 

 species with unusually high median carina; plicae distinct only posteriorly; bottom of 

 postspiracular furrow dull, densely punctured, not subdivided. Femoral depression of 

 mesopleurum fairly deep; upper mesepimerum with nearly smooth interspaces, its punctures 

 coarser and less dense than the irregular puncturation of upper mesepisternum. Fore tibia 

 dorsally rounded, femur dorsally edged but not carinate, ventrally rounded. Hind coxa 

 moderately stout, rather densely clothed with long hairs which in depression point obliquely 

 downward; puncturation dense but looser just above lateral edge and still sparser in a strip 

 below dorsal edge; this edge narrowed posteriorly into a thin, long, slightly raised lobe. Hind
