REVISION OF LEUCOSPIDAE 75 



as broad as high; face very densely rugulose-punctured, pubescence very dense, white, short; 

 interantennal area not keeled; sculpture on lower face more longitudinally rugulose; clypeus 

 about 1 -2 times as broad as high, lower margin bilobed, hardly reflexed, without median tooth. 

 Notch of mandibles small. Relative measurements: width of head 87, frontovertex 49, scrobes 

 24, lower face between eyes 48-5, its height 33, eye 45 : 31, malar space 15, mouth 33. Flagellum 

 plus pedicellus nearly 1-2 times as long as breadth of head, moderately clavate; first flagellar 

 segment distinctly constricted in basal half, slightly longer than pedicellus, fully 1-4 times, 

 second i-8 times, fifth 1-4, eighth 0-95, clava fully i-6 times, as long as broad. 



Pronotal sides arcuately converging, hind margin broadly emarginate, dorsum regularly 

 convex, densely punctured, interspaces distinct though narrow, not shiny owing to faint 

 microscopic cross-striation ; lateral panel deeply depressed, lower corner nearly rectangular. 

 Mesoscutum convex, puncturation as on pronotum. Scutellum 1-2 times as broad as long, 

 weakly regularly convex, hind margin slightly produced, without admarginal depression. 

 Dorsellum nearly 3 times as broad as long, subangularly crescentic, flat, hind margin sharply 

 narrowly carinate, narrowly translucent; dorsally beset with piliferous punctures slightly 

 smaller than those on scutellum. Propodeum medially barely longer than dorsellum, median 

 carina vague, plicae indicated by blunt convexities; pubescence fairly dense, in middle directed 

 forwards. Violaceous upper mesepimerum with punctures as coarse as on metapleurum, 

 interspaces silky shiny, at higher magnification with extremely fine subhorizontal striation; 

 mesopleural depression deep, almost reaching level with lower end of epicnemial depression, 

 edge behind latter depression with narrow but distinct interspaces. Metapleurum dorsally 

 with subrectangular tooth projecting caudad. Fore femur and tibia dorsally strongly carinate. 

 Hind coxa dorsally with a flat area tapering apicad, to slender translucent flat tooth; very 

 densely punctured and pubescent even in depression which is nearly twice as long as broad, 

 with hairs directed uniformly towards apex of lateral edge. Hind femur moderately slender 

 (Text-fig. 79), densely regularly punctured, with short dense pubescence directed to ventral 

 edge which has large narrowly triangular basal tooth and 10-13 small teeth. Hind tibia 

 externally densely finely punctured, outer spur on apical spine short but conspicuous. Stigmal 

 vein of fore wing with terminal processus slightly broader than and about twice as long as uncus. 



Gaster about 2-8 times as long as broad, slightly constricted behind first tergite, densely 

 punctured and clothed with short regular pubescence. First tergite 0-7 the width of gaster, 

 itself 1 -4 times as long as broad; diverging ovipositorial furrows reaching base inside of blunt 

 latero-basal keels; top of median keel smooth. Fourth tergite posteriorly subangulate, medially 

 about one-sixth as long as the first, its median ridge finely grooved; ventro-laterally tergite 

 twice as long as dorsally. Fifth tergite medially about 4 times as long as the fourth, finely 

 grooved. Ovipositor straight, sheaths apically hardly broadened, reaching apex of propodeum. 



(J. S^^-o mm. Head and thorax with pattern similar to $ but yellow on tibiae slightly 

 reduced. First tergite dorsally broadly yellow, hind margins of tergites 3-5 with yellow 

 bands, sixth tergite in middle with a band expanding laterally forwards but sometimes interrupted 

 in median line; also sternites 2-4 broadly yellow (on following ones interrupted medially). 

 Propodeum and first tergite partly red instead of black; antenna more reddish beneath than in $ 

 and relatively slightly shorter, distal funicular segments distinctly transverse. For dorsal 

 aspect of gaster see Text-fig. 80. Sternites 3-7 transverse, the fourth about 2-4 times, the 

 seventh (last) nearly 1 -8 times as broad as long, trapezoidal, barely longer than breadth of its 

 truncate apex; sternites up to fifth distinctly convex, sixth medially broadly depressed, seventh 

 depressed in triangular basal area not reaching apex, its surface rather densely and finely 

 punctured whilst the preceding sternites are very coarsely and not densely punctured.
