Leucospis clavigaster sp. n. 



(Text-fig. 114) 



(J. 7 mm. Black, with dark metallic tinge which is brighter greenish or cupreous on vertex 

 and face (bluish on frons), propodeum and sides of thorax, basal tergites, fourth and fifth 

 tergite posteriorly and on the sixth except basally ; yellow are : scapus, narrow lines anteriorly 

 and posteriorly on pronotum, hind margin of mesoscutum, base of first tergite, dorsal edge of 

 hind coxa, fore and mid knees, narrowly hind femur on dorsal edge and ventro-basally, hind 

 tibia subbasally; tarsi pale testaceous. Wings moderately brownish, slightly darker along 

 anterior margin. 



Head dorsally about 2-15 times as broad as long, about as broad as pronotum; temples very 

 short but distinct. Occipital carina complete, medially strongly inflexed forward, touching 

 ocelli; ocellar triangle strongly raised, about 2-6 : 1; POL : OOL as 11-5 : 7-5; frontal 

 protuberances rounded in dorsal view but scrobes strongly carinate, not touching median 

 ocellus. Head in facial view 1 -2 times as broad as high, face slightly swollen, supraclypeal area 

 not raised, median keel between antennae blunt but distinct. Relative measurements: width 

 of head 58, frontovertex 34, scrobes (width) 15, lower face 32-5, its height 23, eye 34 : 22 (inner 

 orbits hardly emarginate), malar space 6-5, mouth 26, scapus 15. Clypeus flat, about i»a times 

 as broad as high, lower margin weakly produced, medially depressed, hardly emarginate. 

 Flagellum rather strongly clavate, subapically nearly twice as broad as pedicellus, both parts 

 combined nearly 1-2 times as long as breadth of head; pedicellus subglobose; first flagellar 

 segment obconical, about i-6 times as long as broad, slightly longer than the second, the 

 following segments subequal in length but increasing in width, eighth slightly transverse, clava 

 subacuminate, nearly as long as two preceding segments combined. 



Pronotum strongly transverse, dorsally weakly convex, sublaterally nearly flat; hind margin 

 broadly emarginate, sides barely converging, straight; premarginal carina indistinct; lateral 

 panel fairly concave, a small adspiracular area separated by a short vertical carina, lower corner 

 obtuse-angular. Mesoscutum strongly convex, puncturation dense, very narrow interspaces 

 partly raised in short transverse rugae, otherwise microscopically cross-striate. Scutellum 

 nearly flat, fully 1-2 times as broad as long, in posterior half interspaces with longitudinal 

 striation and punctures partly confluent; not depressed at hind margin which is subangularly 

 produced medially; axillar furrows strongly converging. Dorsellum semicircular-crescentic, 

 margin carinate; surface slightly convex, coarsely punctured and with some hairs, at marginal 

 carina alveolate. Propodeum medially raised and 1-7 times as long as dorsellum; median 

 carina and plicae moderate, slightly irregular; median area coarsely rugose-punctured, hairs 

 not very dense, directed headwards. Upper mesepisternum densely punctured, upper 

 mesepimerum less densely so, on disc with smooth interspaces but at metapleural margin with 

 subvertical striae. Fore femur dorsally distinctly carinate, tibia dorsally more bluntly so. 

 Hind leg similar to L. ignota, but hind coxa in depression more densely punctured, without 

 impunctate area, dorsal edge ending posteriorly rather abruptly, suggesting an angulate 

 narrowly translucent lobe ; hind tibia apically less widened, clearly narrower than dorsal length 

 of basitarsus. Fore and mid claws cleft apically, apart from subbasal comb (as in ignota). 

 Fore wing : apical processus of stigmal vein about as long as uncus, but broader.
