REVISION OF LEUCOSPIDAE 125 



Leucospis parvula sp. n. 



(Text-figs 144-148) 



9. 6-8 mm. Black, with following parts pale to lemon-yellow: vertical streaks along eyes 

 on face, scapus beneath, narrow cross-band anteriorly on pronotum broadened on shoulders but 

 often interrupted before reaching them or still more reduced, spot on upper mesepisternum, 

 upper corner of metapleurum, broad streak obliquely diverging from base of fifth tergite and 

 nearly reaching its postero-lateral corner, hind coxa dorsally and ventro-apically, hind femur 

 broadly along dorsal, basal and ventral margins, fore and mid tibiae dorsally, fore femur with a 

 spot; fore and mid legs and hind coxa beneath usually red, as well as tarsi. Yellow often more 

 reduced, in extreme case pronotum wholly black, streaks on gaster reduced to oblique spots at 

 base of fifth tergite, yellow on hind femur at teeth reduced to a spot. Wings distinctly infuscate 

 but narrowly subhyaline at base and on the folding line in the middle. 



Head slightly broader than pronotum, dorsally about 2-2 times as broad as long, with temples 

 extremely short. Occipital carina arcuate, not touching ocelli and not reaching eyes, occiput 

 below carina conspicuously hollowed. POL about or nearly twice OOL; ocellar triangle about 

 2*7 : i-o; vertex convex, densely rugose-reticulate; scrobal margin completely carinate, dorsally 

 almost one-third of diameter from ocellus; frontal protuberances moderately convex. Head in 

 facial view less than 1-2 times as broad as high; eye orbits hardly emarginate; pubescence on 

 face short, white, not extremely dense; face convex at median line, interantennal area with low 

 keel; clypeus about 1-2 times as high as broad, lower margin slightly produced, stout median 

 tooth longer than subtriangular side lobes. Relative measurements: head width 64, 

 frontovertex 35, scrobes at toruli 22, lower face 29, its height 30, eye 3y5 : 25-0, malar space 

 12, mouth 22. Flagellum subfiliform, combined with pedicellus about 1-3 times as long as 

 breadth of head; first flagellar segment hardly Ion ellus, slightly oblong; following 



segments slightly elongate, the eighth transverse; clava subacuminate, about i-8 times as long 

 as broad. 



Thorax densely punctured; narrow interspaces, where distinct (as on scutellum and sublaterally 

 on mesoscutum) microscopically reticulate, dull; pubescence whitish but thin, fairly short. 

 Pronotum transversely depressed, depression delimited anteriorly by arcuate slightly convex 

 swelling and posteriorly by a still vaguer convex cross-line in place of the missing premarginal 

 carina; sides emarginate; lateral panel coarsely punctured and convex (shoulder), except at 

 subangulate lower corner; panel hardly extending backwards beyond middle of collar. 

 Mesoscutum convex; parapsidal vestiges reduced to small pits. Scutellum 1-40- 1-48 times as 

 broad as long ; hollow below, its side margin very deep. Dorsellum with two broad blunt tubercles 

 sometimes subcarinate posteriorly. Propodeum very uneven, elevated median part bearing 

 high median carina and irregular rugae between deep depressions inside of strong plicae; 

 spiracles broad; pubescence moderate. Furrows separating upper mesepisternum from 

 mesepimerum (this furrow crenulate) and on both sides of metapleurum broad and deep. Hind 

 coxa: depression regularly punctured except dorsally where smooth, also yellow dorsal edge 

 smooth, rounded, without mesal carina; ventral face of coxa basally with small smooth convex 

 area, otherwise rather densely punctured, ventro-mesal edge in middle curved and subcarinate. 

 Hind femur (Text-fig. 147) externally densely finely punctured, partly rugulose. Stigmal vein 

 of fore wing wedge-shaped, terminal processus angulately indicated, uncus long, subparallel to 

 postmarginal vein. 



Gaster (Text-fig. 148) long-oval, about 1-9 times as long as broad. First tergite slightly 

 transverse, punctured, interspaces anteriorly in part broader than punctures but much narrower 

 elsewhere, slightly dull owing to very faint reticulation. Fourth tergite densely punctured, 

 medially with distinct ovipositorial furrow tapering forwards; hind margin nearly straight. 

 Fifth tergite convex but arcuately sloping, medially about as long as first tergite and with 

 regular deep ovipositorial furrow; pubescence rather short, puncturation dorsally coarse, 

 interspaces not very narrow. Ovipositor sheaths usually reaching base of fifth tergite, about 

 o-8 length of hind tibia.
