225, 233) ; hind coxa usually more slender, in any case dorsal edge broad, flat or

 exception: L. micrura, Text-fig. 236); ovipositor oblique, never quite reaching 

 base of fifth tergite ; Indo-Australian species ....... 25

each side with diverging dorsal carina ; hind coxa rather narrow ; apex of hind tibia 

 with distinct spine; discal carina on pronotum usually not indicated; ovipositor 

 reaching thorax, first tergite in ^ with double furrow subdivided by smooth ridge 

 which is anteriorly much broader than each branch of furrow; N. India to Japan 



japonica Walker (p. 194) 



— Hind femur either more extensively yellow or basal spot not crossing to dorsal 



edge ; dorsellum bidentate or at least with high and less regular carina ; hind coxa 

 broader (Text-fig. 172), apex of hind tibia less produced; discal carina on pro- 

 notum absent or present; ovipositor sometimes shorter, first tergite in 9 otherwise 21 



21 Pronotum without discal carina; dorsellum distinctly bidentate; 9 gaster notably 



inflated, ovipositor reaching only to base of fifth tergite, first tergite without 

 ovipositorial furrow . . . . . . . . . . .22 



— Pronotum with distinct discal carina, usually embedded in black colour; dorsellum 



subbidentate ; ovipositor reaching at least posterior part of first tergite, this in $ 



with distinct ovipositorial furrow ......... 23 



22 West Palaearctic; pale markings yellow; thorax and gaster densely punctured, hind 



coxa in depression and first tergite medially almost without interspaces, hind 

 femur with very narrow ones; in 9 fourth tergite in middle distinctly less than 

 half as long as first tergite (up to 0-4 : 1); sheaths of ovipositor slightly longer 

 than hind tibia . ....... biguetina Jurine (p. 147) 



— North Chinese; markings pale orange; body, in particular the gaster, sparsely 



punctured; first tergite with smooth median streak, submedially with interspaces 

 almost as broad as punctures; hind coxa extensively smooth in depression, hind 

 femur with interspaces nearly as broad as punctures ; in 9 fourth tergite in middle 

 distinctly longer than half (about o-6) of first tergite; sheaths slightly shorter 

 than hind tibia ....... aurantiaca Shestakov (p. 196) 



23 First tergite in § with ovipositorial furrow strongly tapering forwards, ovipositor 



reaching at most to hind third of first tergite; in $ lobes of clypeus very low, 

 rounded, their outer margins rugulose, hardly raised; basal flagellar segments 

 subquadrate or slightly transverse; hind femur generally broader than in alter- 

 nate, at most i-6 times as long as broad (Text-fig. 175) . bifasciata Klug (p. 146) 



— First tergite in ^ with furrow not narrowed anteriorly, ovipositor reaching at least 



middle of first tergite (usually reaching thorax); in $ side lobes of clypeus tri- 

 angular, outer margins distinctly raised, usually lamellate and converging at 

 angle less than 120 degrees; basal flagellar segments usually distinctly longer than 

 broad ; hind femur slenderer .......... 24
