REVISION OF LEUCOSPIDAE 139 



extent on thorax and, more extensively, on legs. Wings subhyaline; fore wing with weak 

 though distinct brownish streak at postmarginal vein and, abruptly, on apical sixth. 



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

 short temples strongly receding, rounded. Vertex fairly convex, very coarsely rugose-punctured ; 

 occipital carina arched, not high, not reaching beyond lateral ocelli; area between large ocelli 

 not distinctly raised, ocellar triangle about 27 : 1; POL about 4 times OOL, latter subequal 

 to diameter of lateral ocellus, median ocellus about half its diameter from arched scrobal carina; 

 frontal protuberances weak, their upper side distinctly sloping. In facial view head nearly 

 1-2 times as broad as high. Pubescence of eyes extremely short, on face of medium length and 

 density; face vertically rugulose, more densely so beneath, moderately shiny, flat but medially 

 slightly raised, interantennal area with smooth strip on weak keel. Clypeus slightly transverse, 

 subtriangular, its lower margin slightly produced, depressed mesad, side lobes distinct and 

 slightly exceeding short median tooth. Mandibles with lower tooth sharp, short, separated 

 by sharp-angular notch, upper part of edge distinctly emarginate so that mandible appears 

 3-toothed. Relative measurements: width of head 65, frontovertex 40, scrobes 19, lower face 

 33, its height 23, eye 38 : 20, m • e 10, mouth 21, scapus 17, pedicellus 7, riagellum 49. 



Flagellum plus pedicellus about 0-85 times as long as width of head, stout but only subclavate, 

 moderately expanding from base (Text-fig. 168); pedicellus dorsally half as broad as apex of 

 flagellum but distinctly oblong and longer than any of transverse funicular segments of which 

 distal ones are about twice as broad as long; clava 1-2-1 -3 times as long as broad, its apex blunt. 



Thorax densely punctured, narrow interspaces transversely microscopically reticulate-striate; 

 white pubescence short but hairs conspicuous. Pronotum posteriorly emarginate, sides con- 

 verging and nearly straight, shoulders slightly obtuse-angular; collar with a slight arched 

 depression, anteriorly not swollen, sublaterally not depressed, postero-medially convex; hind 

 margin slightly carinate, premarginal carina low but distinct, discal carina absent; lateral panel 

 low, with longitudinal depression below blunt lateral edge, lower corner wide-angular, rounded. 

 Mesoscutum convex, with very slight arched depressions indicating notaular furrows which 

 are stressed furthermore by hairs being directed backwards on mid lobe but obliquely sideways 

 laterad of mid lobe of sclerite; parapsidal vestiges short, strongly diverging. Scntellum about 

 1 *2 times as broad as long, moderately convex except for shallow depressed line of punctures 

 at hind margin; puncturation coarse, interspaces distinct though narrow. Axillae fairly 

 declivous. Dorsellum subcrescentic, nearly flat, bare, rugulose sculpture shallow but with 

 some rugae from anterior margin; posterior margin carinate. Propodeum in middle nearly 

 twice as long as dorsellum, with sharp regular median carina; puncturation dense, pubescence 

 moderate but more conspicuous laterad of distinct low plicae. Side of thorax very coarsely, 

 rather densely and regularly punctured on upper mesopleurum and metapleurum, latter not 

 produced at hind wing; mesopleural depn isioa rather deep. Fore femur rounded dorsally 

 but carinate ventrally towards knee; tibia with slight dorsal and ventro-external carinae. For 

 hind leg see Text-figs 165, 167. Hind coxa: dorsal edge punctured, blunt, broad even posteriorly 

 at distinct dorsal tooth ; depression dull, piliferous punctures confined to median streak accom- 

 panied at sides by streaks of transverse coarse rugulae, lower streak separated from dense 

 puncturation and pilosity beneath by blunt lateral edge; ventro-mesal edge blunt, weakly 

 curved. Hind femur moderately stout, basal tooth the longest, followed by 6-8 smaller teeth 

 which are rather broadly separated from each other except the distal ones. Hind tibia densely 

 punctured, finely densely hairy; external ventral carina extending over three-quarters; apex 

 slightly oblique, with a row of sparse little spines, ventral end slightly produced, outer spur 

 strong; dorsal side of basitarsus distinctly longer than apical breadth of tibia. Pilosity of fore 

 wing only moderately dense; terminal processus of stigmal vein broad, less than half as long 

 as slender uncus which is subparallel to postmarginal vein. 



Gaster (Text-fig. 166) about as long as head plus thorax (in normal position), strongly inflated 

 in posterior third, both in dorsal and lateral views; puncturation dense, pilosity white, fairly 

 conspicuous though decumbent or subdecumbent and not long. First tergite 1 -3-1 -4 times as 

 long as broad, sides diverging caudad, maximum breadth hardly more than half breadth of 

 fifth tergite; hind margin not emarginate; dorsum convex, posteriorly with slightly raised
