REVISION OF LEUCOSPIDAE 199 



instead with a narrow impunctate strip slightly broadening caudad and the 

 yellow cross-band on the fifth tergite is situated near the hind margin and intersects 

 the base of the sheaths. The male was previously unknown. 



<J. 7-3 mm. Colour pattern as in § but gaster with orange cross-bands, one at one-third 

 of broad part, second at two-thirds and with round spot above epipygium apically. Propodeal 

 plicae very strong, high, accompanied by perpendicular short rugae. Gaster (Text-fig. 221) 

 slightly longer than and as broad as thorax. First tergite about as long as broad, subglobose. 

 strongly convex, except in basal quarter (which is impunctate) with dense coarse and mostly 

 rugose puncturation which becomes sparser posteriorly and much finer and sparser laterally. 

 Rest of gaster covered by a dorsally undivided ovoid carapace; its base with suggested median 

 keel and conspicuous short lateral (epipleural) keels; epipleura high, basal ly with raised margins 

 of second and third tergites; apical corners of sixth tergite not distinct; exposed part of epi- 

 pygium rounded, strongly depressed transversely, cercus behind tiny vertical carina. Sternites 

 very narrow (Text-fig. 221): the first with high transverse carinate tooth; following ones 

 shallowly depressed medially, third to fifth and seventh only anteriorly so; fifth 1-5 times as 

 long as broad, seventh (last) hardly longer than broad, its surface apically slightly convex, 

 apical margin semicircular.

(Text-figs 225-227) 



$. 8-o-iO'5 mm. Brownish black but following parts ochreous-yellow: scape, two cross- 

 bands on pronotum, lateral margins of mesoscutum, scutellum except on disc and basally, 

 metapleurum, cross-band on fourth tergite, another band just behind middle of fifth tergite, 

 vertical streaks on epipygium, apical halves of fore and mid femora, all tibiae except beneath, 

 all tarsi, hind coxa dorsally and in distal parts along lateral and ventral edges, hind femur on 

 ventro-basal and broad dorsal streaks. Antennal flagellum brownish to reddish. Fore wing 

 slightly infumate, more intensively so at venation and in apical fifth; venation and tegulae 

 dark testaceous. 



Head hardly broader than pronotum, in dorsal view (Text-fig. 226) nearly 2-2 times as broad 

 as long; occipital carina not high and disappearing behind lateral ocelli; lateral ocellus i-o-i-i 

 its diameter from eye. Ocellar triangle about 2-2 : i-o, POL : OOL as 13 : 6; median ocellus 

 about 0-25 its diameter from scrobal margin. Head in facial view about 1-36 times as broad 

 as high. Face densely covered with slightly brownish pubescence, longer hairs rather abundant 

 and even short hairs distinctly longer than hairs on eyes. Interantennal lobe with weak 

 carina. Relative measurements: width of head 70, of frontovertex 34, face below antennae

 of clypeus 23; the latter with broad median tooth exceeding low lateral lobes. Antennal 

 flagellum subfiliform, combined with pedicellus about 1-2 times as long as width of head; 

 proximal flagellar segments distinctly elongate, the fifth and sixth subquadrate. 



Premarginal and discal carina on pronotum distinct, the premarginal sometimes less con- 

 spicuous owing to yellow band; lateral panel of pronotum not carinately set off, its fovea not
