REVISION OF LEUCOSPIDAE 123 



and fifth tergite postero-medially. Antennae reddish but inluscate subapically, tarsi reddish, 

 also sheaths of ovipositor but for black apex. Dense short pubescence of body whitish. Wings 

 subhyaline, fore wing very slightly infuscate anteriorly and in lines indicating vanished veins; 

 venation brown, basally yellowish. 



Head hardly narrower than pronotum, in dorsal view fully twice (2-0- 2*2) times as broad as 

 long; temples very short but distinct. Vertex densely punctured except for small areas just 

 outside of median ocellus; POL twice OOL, ocellar triangle about 3:1; occipital carina not high, 

 developed only behind ocelli, touching lateral ones and less than one-third diameter from 

 median ocellus; latter ocellus touching indented scrobal carina which is fine but uninterrupted 

 down to toruli ; frontal protuberances low. In facial view head 1 -3 times as broad as high ; face 

 dull, densely rugulose-punctured, white pubescence dense, short; carina of interantennal area 

 fine, irregular. Clypeus hardly broader than wide, upper margin vague, sides strongly diverging, 

 surface almost flat, lower margin narrowly smooth, hardly produced, lobes very short, median 

 tooth distinct. Inner edge of mandibles broadly truncate, notch small. Relative measure- 

 ments: height of head 63, width of frontovertex 47, scrobes 24, lower face 42, its height 30, eye 

 47-0 : 31-5, malar space 11, mouth 33. Flagellum hardly clavate, combined with pedicellus 

 usually fully i-i times as long as width of head; first three flagellar segments oblong, middle 

 segments subquadrate, sixth to eighth slightly transverse, clava nearly i-8 times as long as 

 broad, rounded at apex. In smaller specimens segments relatively shorter than described. 



Thorax dull, extremely densely but not very coarsely punctured. Pronotum with three 

 high carinae: arched marginal, angulate premarginal and (highest) discal, latter carina well 

 before middle of collar ; sides of collar slightly converging, hardly concave, shoulders conspicuous ; 

 lateral panel flat, punctured. Mesoscutum slightly flattened posteriorly, regularly punctured, 

 hairs directed towards middle of anterior margin. Scutellum convex anteriorly, flattened 

 posteriorly, not depressed at broadly rounded hind margin, 1-25-1 -35 times as broad as long. 

 Dorsellum short, bare, with coarse but not deep alveolae, posteriorly with a slight carina 

 lowered in middle; sides of metanotum densely pubescent. Propodeum medially about 

 1-5-2-0 times as long as dorsellum, regularly raised in middle, densely clothed with long hairs; 

 median carina fine, less conspicuous than plicae. Fore tibia with distinct dorsal and externo- 

 ventral carinae, femur not carinate. Hind coxa broad (Text-fig. 136), finely densely punctured 

 and with short pubescence, but a percurrent streak on upper half of depression smooth and 

 shiny; dorsal edge broad, even posteriorly blunt but there on mesal side with fine carina behind 

 dense longer hairs. Hind femur excluding teeth about i-8 times as long as broad; teeth 

 moderately long, the basal the broadest but middle teeth the longest, fairly distant from each 

 other; outer side rather densely and moderately coarsely punctured. Hind tibia externally 

 fairly densely punctured, interspaces about as broad as punctures; apical spine conspicuous 

 with rudiment of spur on top; externo-ventral carina ending one breadth of tibia before apex, 

 latter about o-8 the dorsal length of basitarsus. Stigmal vein of fore wing with terminal 

 processus short, uncus of medium length. 



Gaster about as long as head plus thorax, densely punctured, dull, posteriorly moderately 

 swollen; pubescence short, subdecumbent, rather uniform. First tergite 1-1-1-3 times as long 

 as broad, anteriorly on either side with stout keel, dense hairs converging towards median keel. 

 Fourth tergite short, medially elevated, with deep ovipositorial furrow, its hind margin hardly 

 angulate. Fifth tergite about three-quarters times as long as broad but distinctly longer than 

 the first; its ovipositorial furrow deep, narrow, not carinate at sides. Ovipositor reaching base 

 of fourth tergite. 



. 5-9 mm. Very similar to $, also in colour, but gaster with laterally reduced pale yellow 

 cross-line before middle of carapace, a more extended band behind middle and apex with broad 

 spot on subvertical part, including base of epipygium, spot broadly emarginate above. Some- 

 times also first tergite posteriorly with transverse spot and spots on hind coxa and femur 

 broader than in female, often extending beyond basal tooth. Antennae slightly shorter than 

 in §. Propodeum medially nearly 3 times as long as dorsellum. First tergite hardly longer 

 than broad, hardly half as broad as broad carapace, hind margin straight. Following exposed
