Leucospis genalis sp. n. 



(Text-figs in, 112) 



9. 7-2 mm. Black, with, weak metallic tinge, but gaster posteriorly except basal bands on 

 tergites 3-5 golden to brassy; pale yellow are narrow bands at hind margin of pronotum and 

 mesoscutum, apex of lateral edge of hind coxa, very narrowly all knees, dorsal edge and basal 

 half of ventral edge of hind femur. Antennae black; legs apically more or less brownish; 

 ovipositor sheaths reddish. Wings slightly brownish yellow, more intensively so near the 

 venation. 



Head distinctly narrower than pronotum posteriorly (52-5 : 57-5), dorsally about 2-3 times as 

 broad as long. Occipital carina not high, disappearing half way between ocelli and eye; 

 temples subparallel, nearly one-third the length of eye in dorsal view; POL about 0-9 OOL, 

 ocellar triangle about 2-2 : 1, bluntly elevated between median and lateral ocellus. Scrobes 

 above transversely striate, not carinately bordered. Vertex rugose-punctured, rugae radiating 

 laterad from ocelli; face rugulose-punctured, slightly shiny only on convex disc of supraclypeal 

 area; interantennal lobe not carinate; pubescence whitish, extremely short and not very dense, 

 longer hairs sparse. In facial view head 1-14 times as broad as high (Text-fig. in), height to 

 shortest distance between eyes (below antennae) as 46 : 30, relative width of frontovertex 34, 

 eye 27-5 : 17-0, its inner orbit not emarginate; malar space 11*5, width of mouth 26. Clypeus 

 as broad as high, its lower margin conspicuously produced, bilobate with very small median 

 tooth; relative distance of lower margin from toruli 25. Mandibles with deeply semicircular 

 broad gap separating sharp lower tooth. Scapus ventrally densely punctured, about 3 times 

 as long as broad, relative length 14. Flagellum plus pedicellus combined about 1-15 times as 

 long as breadth of head, weakly clavate; pedicellus hardly longer than broad, first flagellar 

 segment about 1 -5, sixth 1 -i, clava twice, as long as broad ; two preclaval segments subquadrate. 



Puncturation of thorax very dense, coarsest on mesoscutum where some punctures are 

 transversely confluent; interspaces very narrow, without microsculpture ; pubescence mostly 

 extremely short but longer on pale band of pronotum and laterally on scutellum. Pronotum 

 convex, without any carinae; sides in dorsal view converging, straight, hind margin broadly 

 emarginate; lateral panel above convex, shallowly depressed along the broadly rounded lower 

 margins. Mesoscutum convex; vestiges of parapsidal furrows very short. Tegula with 

 punctures along inner margin only, disc impunctate, shiny, faintly alutaceous. Scutellum 1-2 

 times as broad as long, convex, with a row of coarser alveolae at hind margin; hairs directed 

 forward, very conspicuous laterally. Dorsellum subtriangular, about twice as broad as long, 

 bare, coarsely alveolate, its margin with raised sublamellate carina, metanotum sublaterally 

 with a row of large foveae. Propodeum medially about i-8 times as long as dorsellum, the 

 irregular high median carina and plicae distinct ; at base coarsely irregularly clathrate-alveolate 

 and except just at base densely punctured and densely hairy. Upper mesepimerum coarsely
