basal tergite and on the sides. Antennae testaceous ; pedicellus and flagellum darker dorsally ; 

 scape sometimes with a dark streak dorsally. Coxae concolorous with the thorax ; femora 

 black with a metallic tinge, more or less pale at their tips ; remainder of legs testaceous, with 

 the fore tarsi, and the tips of the mid and hind tarsi, fuscous. Tegulae mainly testaceous. 

 Wings hyaline ; venation testaceous. Length 1-7 to 2 mm. 



Head about 1 -2 times as broad as the mesoscutum, in dorsal view 2-25 to 2-35 times as broad 

 as long ; temples about one fifth length of eyes, rounded off ; POL about 1-7 OOL, ocelli in a 

 triangle whose base is nearly three times its height. Eyes separated by about 1-3 to 1-4 times 

 their own length. Head in front view transversely oval, about 1-25 times as broad as high, 

 with the vertex strongly arched, but the cheeks nearly straight in outline. Malar space slightly 

 less than half the length of an eye. Breadth of oral fossa about 2-5 times the malar space. 

 Clypeus about 2-3 times as broad as long, shiny with obsolescent sculpture, its anterior margin 

 produced and almost angulate medially. The head is shiny, with fine, on the vertex very fine, 

 alutaceous sculpture which is not distinctly raised above the general surface. Antenna (Text- 

 fig. 225) with scape nearly as long as an eye, but not quite reaching the median ocellus, 4-5 to 4-8 

 times as long as broad ; combined length of pedicellus and flagellum 1-15 times the breadth of 

 the head ; pedicellus in profile about 1 -7 times as long as broad ; funicle proximally not stouter 

 than the pedicellus, thickening distad, its first segment as long as or somewhat longer than the 

 pedicellus and i-6 to i-8 times as long as broad, the second, and sometimes the third, segment 

 slightly elongate, the fourth and fifth quadrate, or the fifth very slightly transverse ; clava 

 about 2-5 times as long as broad, slightly broader than the funicle, nearly as long as the three 

 preceding funicular segments together ; flagellum with rather bristly hairs which are slightly 

 outstanding. 



Thorax about i-6 times as long as broad. Mesoscutum about i-8 times as broad as long, 

 shining, with very fine reticulation which is hardly raised above the general surface ; mid 

 lobe moderately thickly haired ; notauli deep, slightly curved. Scutellum distinctly longer 

 than the mesoscutum, longer than broad, strongly convex in the transverse axis, shiny, with 

 very fine engraved sculpture, that of the frenum less fine, with three to four pairs of bristles ; 

 frenum marked off by a fine line ; the scutellum also has a short longitudinal impressed line at 

 its base ; the scutello-axillar sutures converge strongly and meet the hind margin of the mesos- 

 cutum well mesad of the notauli, the base of the scutellum being less than one sixth the breadth 

 of the mesoscutum. Dorsellum about half as long as the frenum, shiny, weakly alutaceous. 

 Propodeum medially barely as long as the scutellar frenum, and less than one third as long as 

 the scutellum, shiny and weakly alutaceous or nearly smooth ; median carina weak or absent ; 

 plicae absent ; spiracles circular, touching the metanotum ; callus with several hairs which 

 are distributed from its base right to the supracoxal flange. Metapleuron and most of the meso- 

 pleuron, with fine delicately-engraved sculpture ; mesepisternum with a smooth subtriangular 

 area dorsally ; mesepimeron distinctly marked off from the mesepisternum, about 2-5 times 

 as long as broad ; mesosternum shiny and nearly smooth, mesolcus distinctly impressed. 

 Postspiracular sclerite with somewhat coarse, but hardly raised, sculpture. Legs not stout ; 

 hind coxae rather more than twice as long as broad, with delicate, hardly raised sculpture ; 

 their dorsal surface with some hairs ; spur of mid tibia about two thirds the length of the first 

 tarsal segment. Fore wing about twice as long as broad ; costal cell broad (length : breadth 

 about 8 : 1), its lower surface with scattered hairs, its upper surface with a row of several hairs 

 in the distal third ; basal cell hairy over about its distal third ; speculum closed below, on the 

 upper surface of the wing moderate-sized and not extending below the marginal vein ; wing 

 beyond the speculum thickly hairy ; marginal vein (Text-fig. 226) i-i to 1-25 times as long as 

 the postmarginal vein and 2 to 2-2 times as long as the stigmal vein ; the latter slightly curved, 

 the stigma moderate-sized and suboval, with a moderately long uncus ; submarginal vein with 

 12 to 15 bristles. 



Petiole of gaster strongly transverse. Gaster lanceolate, even without the ovipositor some- 

 what longer than the head plus thorax, slightly narrower than the thorax, acute apically, 

 3 to 4-2 times as long as broad ; basal tergite with a semicircular basal fovea ; disc of gaster
