4 Hind margin of dorsellum rounded ; depression of hind coxa medio-posteriorly with 



impunctate area, puncturation above rather sparse; first tergite in § with two 

 broad ovipositorial furrows diverging forward and separated anteriorly by broad 

 coarsely punctured ridge; India to Queensland . . histrio Maindron (p. 164) 



- Hind margin of dorsellum emarginate or bidentate; hind coxa usually without 



distinct impunctate area, puncturation in depression dense, only in its upper 

 part interspaces sometimes as broad as punctures ; first tergite in <j> with smooth 

 parallel-sided ovipositorial furrow which may be subdivided by blunt median 

 keel but this is not punctured ; south-west Asia to India .... 5 



5 Hind femur externally very finely punctured; dorsellum posteriorly slightly 



emarginate ; in ^ first tergite with narrow and strongly converging yellow streaks

- Hind femur coarsely punctured; dorsellum distinctly bidentate; first tergite in $ 



broadly yellow laterad of ovipositorial furrow ...... 6 



6 In $ flagellar segments 2-4 subquadrate, in g subtransverse ; face short (Text-fig. 187), 



lower margin of clypeus only slightly produced; ovipositor reaching to base of 

 gaster or further forward; body smaller, up to 13 mm .intermedia Illiger (p. 153) 



- Flagellar segments 2-4 in both sexes distinctly longer than broad or the fifth 



sometimes subquadrate in ^; face longer (Text-fig. 1), lower margin of clypeus 

 conspicuously produced and raised, strongly bilobed ; ovipositor generally shorter, 

 often not reaching base of gaster; body up to 15 mm . gigas Fabricius (p. 149) 



7 Interocellar area traversed by high ridge parallel to occipital carina and highest 



between lateral and median ocellus, ocelli unusually small (Text-figs 185, 186), set 

 very deep, lateral ocellus at least 1 -8 times its diameter from median ocellus, this 

 separated from scrobes by transverse striae; mesoscutum in posterior two-thirds 

 more shallowly, coarsely and less densely punctured than anteriorly; gaster red 

 except apically; Philippines. ......... 8 



- Interocellar area not unusually raised, ocelli not very small, not set deep, the lateral 



hardly more than its diameter from median ocellus; mesoscutum and gaster 

 often otherwise ............ 9 



8 7mm; sculpture on mesoscutum posteriorly only slightly obliterated; scrobal 



margin in front of median ocellus not conspicuous, merging with transverse striae ; 

 apical processus of stigmal vein less than half as long as uncus, wings weakly 

 infumate ......... pulchella Crawford (p. 180) 



- More than 12 mm; sculpture on mesoscutum posteriorly considerably obliterated; 



scrobal margin sharply carinate in front of ocellus; apical processus of stigmal 



vein more than half as long as uncus, wings dark brownish banksi Weld (p. 180) 



9 Gaster in both sexes dorsally sparsely punctured (Text-fig. 192), interspaces on 



broadest part mostly broader than punctures; body mainly black, wings dark 

 violaceous; tooth of hind coxa conspicuous, upper part of depression and dorsal 

 edge of coxa mostly without punctures (Text-fig. 193); mesoscutum in posterior 

 two-thirds usually much more shallowly and less densely punctured than anteriorly, 

 punctures usually transversely confluent ....... 10 



- Gaster densely punctured, interspaces never broader than punctures, but if 



relatively broad and coxa as in alternate, then wings much paler and body with 

 yellow markings ........... 11 



1 o Pilosity of body blackish, short, propodeum laterally with greyish hairs ; hind femur 

 and tibia externally rather sparsely punctured; puncturation on mesoscutum 

 posteriorly partly effaced, on first tergite in § with broad interspaces but with 

 median smooth streak rather reduced (Text-fig. 192); pale markings absent or at 

 least poorer than in alternate, absent (Palways) on hind femur; Solomons, New 

 South Wales ........ nigerrima Kohl (p. 181) 



- Pilosity mainly whitish, only on vertex and thoracic dorsum partly dark, on 



propodeum laterally very conspicuous, white, much longer than length of spiracle;
