hind femur and tibia externally densely and rather finely punctured, puncturation 

 on mesoscutum distinctly deeper than in alternate, on first tergite in § less sparse 

 but leaving a broad median streak impunctate; white markings: scapus beneath, 

 two pronotal lines, apex of propodeum, two points postero-laterally on first 

 tergite and ventro-basal and dorso-apical streaks on hind femur; New Britain, 

 New Ireland ........ buchi Hedqvist (p. 181) 



11 Body, except the dark brown or black head, with rich orange-yellow and reddish 



markings, pronotum mainly yellow except for median transverse spot, hind 

 femur broadly yellow at base and below dorsal edge, first tergite extensively 

 yellow posteriorly; Australia. .... atriceps (Girault) (p. 178) 



- Body less extensively pale-marked ; mostly more northerly ..... 12 



12 Malar space 0-17-0-19 the length of eye (Text-fig. 188), about as long as breadth of 



second flagellar segment; hind coxa in depression extensively punctured, dorsal 

 edge externally often with distinct sublamellate tooth; hind femur moderately 

 coarsely and not very densely punctured, yellow colour forming (mostly) separated 

 broad streaks ventro-basally and dorso-apically; in £ broad part of gaster with 

 two yellow bands, the anterior broader; China to Japan .sinensis Walker (p. 179) 



- Malar space 0-22-0-30 the length of eye, at least 1-2 times as long as breadth of 



second flagellar segment (Text-fig. 189); hind coxa in depression dorso-posteriorly 

 more or less smooth, tooth often indistinct; hind femur densely finely punctured; 

 yellow or whitish markings usually more reduced than in alternate; from India 

 and Philippines to Queensland .... petiolata Fabricius (p. 174) 



13 Hind femur behind basal tooth with more or less irregular, often not very small 



teeth (Text-figs 212, 219) ; apex of hind tibia truncate or acuminate ... 14 



- Hind femur behind basal tooth with a comb of very minute regular teeth (Text-figs 



225, 233) ; hind tibia not produced into a spine ...... 27 



14 Pronotum: discal carina absent or weak and if conspicuous, it is never unusually 



raised, nor its margin directed backwards; even premarginal carina sometimes 

 weak .............. 15 



Note: species with medium discal carina may be run both ways. 



- Discal carina of pronotum high and, even if short, subangulately raised, with 



margin highest in the middle and directed backwards (Text-figs 194, 198); pre- 

 marginal and marginal carinae also high, very conspicuous .... 36 



15 Hind coxa dorsally with distinct tooth, below the tooth densely punctured; 



dorsellum bidentate; ovipositor reaching base of gaster or nearly; Australia. . 16 



- Hind coxa without distinct dorsal tooth or, if a tooth indicated, the area just below 



extensively smooth; dorsellum not distinctly bidentate, except in some Palae- 

 arctic (Mediterranean) species; ovipositor often shorter; mostly non- Australian 

 (exceptions: L. giraulti, L. aruina) ........ 19 



16 Scutellum at median line with extremely fine puncturation, dull, but laterally 



coarsely punctured; dark parts of body bright metallic green, red or blue 



morawitzi Schletterer (p. 190) 



- Scutellum medially nearly as coarsely punctured as laterally; body often non- 



metallic ............. 17 



17 Pale markings red-orange; spots on scutellum, if large, broadly connected (some- 



times absent); pronotum with transverse spot or band anteriorly; first flagellar 

 segment very narrow basally and much longer than pedicel ; dorsellum with short 

 teeth; first tergite in $ dorsally with two broad diverging ovipositorial furrows 

 which are densely punctured on bottom ; in £ median carina of propodeum raised 

 into high tooth ........ australis Walker (p. 193) 



- Pale markings at least in part yellowish orange or ochreous; pronotum posteriorly 



with broad band produced forward medially and laterally; scutellum with two 

 elongate and usually separated maculae ; first flagellar segment at most 1 -3 times 

 as long as pedicel; teeth of dorsellum sharp; first tergite in $ with one median
