REVISION OF LEUCOSPIDAE 137 



streaks on hind femur; tarsi pale testaceous; pronotum reddish posteriorly. Pubescence of 

 body whitish, short, inconspicuous. Wings brownish, darker infuscate along anterior margin. 



Head slightly broader than pronotum posteriorly, in dorsal view twice as broad as long; 

 temples developed though short. Vertex densely umbilicately punctured leaving free only 

 narrow space laterad of each ocellus; ocellar area not raised, ocellar triangle about 2-5 : 1, 

 median ocellus about one-third its diameter from strong scrobal carina and about half its 

 diameter from occipital carina, latter low and disappearing beyond lateral ocelli; POL about 

 2-i times OOL; frontal protuberances rather strong. Head in facial view fully 1-3 times as 

 broad as high; face dull, very densely rugulose-punctured, pubescence extremely short; inter- 

 antennal area hardly raised medially, with smooth blunt keel. Relative measurements: width 

 of head 73, frontovertex 40, scrobes 26, lower face 33, its height 26, eye (inner orbit distinctly 

 emarginate) 44 : 31, malar space 9, mouth 31, scapus 18. Clypeus slightly broader than long, 

 with sides straight, converging upwards, lower margin not produced, depressed on either side 

 of short and broad median tooth, lateral lobes very short. Truncate inner edge of mandible 

 broad, notch small; surface smooth apically, in the middle with shallow longitudinal grooves. 

 Flagellum plus pedicellus 1-3 times as long as breadth of head, subclavate; pedicellus oblong; 

 first flagellar segment basally barely attenuate, about 1 -j times as long as broad, covered with 

 same kind of sensilla as following segments which are decreasing in length, distal funicular 

 segments subquadrate; clava subacuminate, hardly shorter than two preceding segments 

 combined. 



Thorax densely punctured, dull, very shortly pubescent, narrow interstices microscopically 

 cross-striate, on mesoscutum interstices slightly raised in transverse rugae. Pronotum with 

 sharp raised straight hind margin and high premarginal carina, in front of the latter distinctly 

 transversely depressed, depression delimited anteriorly by a swelling marked yellow and 

 reaching anterior corners of pronotum; sides broadly emarginate; lateral panel slightly depressed 

 below swollen lateral edge of collar, flat beneath. Mesoscutum, except anteriorly, subdepressed 

 in place of notaular furrows. Scutellum about 1-2 times as broad as long, convex, with 

 impressed line of punctures at smooth hind margin. Dorsellum fully 3 times as broad as long, 

 shiny, swollen, sausage-like, its margin rounded, surface with sparse tiny punctures and micro- 

 scopic cross-reticulation. Propodeum medially only slightly longer than dorsellum, a quarter 

 the length of scutellum; plicae very distinct but median carina weak though slightly raised 

 posteriorly; median area punctured, hairs very short, but pubescence very dense and con- 

 spicuous outside of plicae. Both parts of upper mesopleurum convex, rather densely punctured, 

 interspaces smooth. Metapleurum on disc nearly impunctate. Legs very slender. Fore femur 

 dorsally rounded, tibia dorsally and ventro-externally with a faint carina. Hind coxa extremely 

 densely and finely punctured, with short hairs, along lateral edge subventrally punctures less 

 dense; dorsal edge punctured, broad, posteriorly with small narrow tooth; depression with two 

 percurrent smooth streaks meeting posteriorly, separated by median punctured streak. Hind 

 femur (as in Text-fig. 163) with basal tooth the largest, median teeth rather slender; external 

 surface moderately densely and rather finely punctured, interspaces with very shallow micro- 

 reticulation. Hind tibia: outer ventral carina nearly reaching apex; latter subemarginate 

 but ventrally produced into long spine with sharp outer spur on top (Text-fig. 164). Stigmal 

 vein of fore wing with long uncus but terminal processus missing. 



Gaster (Text -fig. 162) nearly 2-8 times as long as broad, petiolate, posterior part broadly 

 fusiform and densely punctured. First tergite hardly half as broad as gaster, nearly 2-2 times 

 as long as broad, sides subparallel; its dorsum with unusually high smooth swollen median ridge, 

 highest in basal third, separating diverging shallow ovipositorial furrows which are laterally, 

 as well as sides of the tergite, moderately densely punctured; hind margin rather broadly 

 smooth, in middle with tiny excision. Fourth tergite expanding backwards, very short, 

 punctured; its hind margin straight, dorsum with fine groove in median line. Fifth tergite 

 strongly swollen behind middle, narrowing basad, dorsally convex and with deep ovipositorial 

 furrow. Apex of gaster in dorsal view sub-acuminate. Ovipositor reaching dorsellum. 

 Hypopygium reaching level with base of ovipositorial sheaths.
