bronze ; base of gaster greenish. Mandibles testaceous with reddish teeth. Antennae testa- 

 ceous ; sometimes scape at apex, and pedicellus more or less dorsally, brown ; flagellum dor- 

 sally brown. Coxae concolorous with the thorax ; trochanters more or less infuscate ; femora 

 bronze-black, their tips, those of the fore and mid femora broadly, of the hind ones narrowly, 

 testaceous ; tibiae testaceous, tarsi paler testaceous with their fifth segment brown. Tegulae 

 brownish testaceous. Wings hyaline ; venation testaceous. Length 1-7 to 1-95 mm. 



Head about 1 -2 times as broad as the mesoscutum, in dorsal view strongly transverse, breadth 

 to maximum length about 2-35 to 2-4 : 1, with POL about 1-25 OOL, the ocelli in a triangle 

 whose base is about 2-25 times its height ; temples extremely short. Eyes separated by 

 about 1-4 times their own length. Malar space slightly more than one third the length of an 

 eye. Breadth of oral fossa nearly three times the malar space. Clypeus (Text-fig. 215) about 

 twice as broad as long, its anterior margin produced but shallowly emarginate medially. Mandi- 

 bles moderate-sized, hardly falcate, their lower margin weakly sinuate ; teeth acute, not very 

 dissimilar in length although the outer one as usual is rather longer than the others. Head 

 with extremely fine reticulation which is not or hardly raised above the general surface. An- 

 tenna (Text-fig. 223) with scape much shorter than an eye and not nearly reaching the median 

 ocellus ; combined length of pedicellus and flagellum slightly less than the breadth of the head ; 

 pedicellus in profile about 1-5 times as long as broad ; funicle proximally hardly stouter than 

 the pedicellus, but thickening distad, its first segment about as long as the pedicellus and 1-5 

 to i-6 times as long as broad ; second and following segments subquadrate ; clava slightly 

 more than twice as long as broad, slightly broader than the funicle, nearly as long as the three 

 preceding funicular segments together. Thorax nearly 1-5 times as long as broad. Meso- 

 scutum about 1 -6 times as broad as long, slightly shiny, with extremely fine alutaceous sculpture 

 which is hardly raised above the surface, with numerous bristles which arise from small warts ; 

 notauli deep, straight. Scutellum about as long as mesoscutum, distinctly longer than broad, 

 strongly convex in the transverse axis, sculptured like the mesoscutum ; frenum marked off by 

 a fine grooved line ; the scutello-axillar sutures curve round and join anteriorly, so that the 

 scutellum touches the mesoscutum only in the middle. Axillae sculptured like the scutellum. 

 Dorsellum shiny, weakly alutaceous, shorter than the frenum. Propodeum strongly transverse, 

 medially hardly more than one third as long as the scutellum, shiny, weakly alutaceous ; median 

 carina fine but complete ; plicae indicated at the hind margin of the sclerite ; spiracles circular, 

 touching the metanotum ; callus with five to six bristles. Metapleuron and mesepimeron 

 rather shiny, with moderately fine delicate reticulation ; mesepimeron distinctly separated 

 from the mesopleuron, about 2-5 times as long as broad ; mesosternum delicately reticulate 

 laterally, nearly smooth medially, its mesolcus distinctly impressed, at least posteriorly. Legs 

 not stout ; hind coxae about twice as long as broad, with delicate sculpture which is only very 

 slightly raised above the general surface ; their dorsal surface with a few hairs ; spur of mid 

 tibia about two thirds the length of the first tarsal segment. Fore wing slightly more than twice 

 as long as broad ; costal cell broad (length : breadth about 7 : 1 ) , its lower surface sparsely hairy, 

 its upper surface with a row of several hairs in the distal half ; basal cell, on the upper surface 

 of the wing, with its distal quarter hairy ; speculum closed below, on the lower surface of the 

 wing partly effaced by scattered hair-bases ; wing beyond the speculum moderately thickly 

 haired ; marginal vein as long as or very slightly (up to 1-15 times) longer than the postmarginal 

 vein, and 1-4 to 1-5 times as long as the stigmal vein ; stigma moderate-sized, subrectangular, 

 its uncus long. 



Gaster obovate, broadest slightly behind the middle and narrowing gradually basad ; about 

 as long and as broad as the thorax, 1 -25 to 1 -55 times as long as broad, obtuse or bluntly pointed 

 apically ; basal tergite occupying one third of the total length or rather more, with a triangular 

 basal fovea, and with a grooved impression running back from the fovea for some distance ; 

 beyond the basal tergite the gaster is slightly concave dorsally ; ventrally it is moderately 

 convex, with the hypopygium reaching about half way along.
