Hind coxa with smooth streak in upper half of depression (Text-fig. 136) ; pubescence 



of body subdecumbent, short but rather dense; mainly brownish black, whitish 



markings reduced to anterior line on pronotum, dorsal edge of hind coxa, base of 



hind femur and in $ a band on fourth tergite; Madagascar pubescens sp. n. (p. 122) 



Hind coxa punctured, without smooth streak; pubescence semi-erect or erect, longer 



than in alternate ; markings otherwise, usually richer ; non-Madagascan . . 3 



Dorsellum at hind margin more or less carinate and usually shortly bidentate; 



dorsally often without hairs; discal carina of pronotum not high ... 4 



Dorsellum convex, its margin rounded, not bidentate, dorsally beset with piliferous 

 punctures; if hind margin subcarinate, then discal carina of pronotum high, 

 angulate ............. 8 



Ethiopian (south of Sahara) ; hind femur with middle teeth longer than basal tooth 

 which often is not broad, sometimes oblique (Text-fig. 126); discal carina 

 narrowly lamellate, its high translucent margin directed backwards; pubescence 

 of body relatively long; ovipositor not reaching base of fifth tergite 



africana Cameron (p. 106) 



Palaearctic or North African (including Sudan) ; hind femur with middle teeth mostly 

 shorter than basal tooth which is broadly triangular, not oblique (Text-figs 172- 

 175); discal carina mostly otherwise; pubescence short; ovipositor often longer 

 than in alternate ........... 5 



Discal carina short but subangulately raised, its thin lamellate margin turned back- 

 wards; ovipositor sheaths shorter than hind tibia and not reaching base of fifth 

 tergite (Text-fig. 1 70) ; upper edge of hind coxa even posteriorly not very thin ; 

 hind tibia black but hind femur extensively yellow; in £ gaster narrowly petiolate 

 (Text-fig. 169), similar to africana . . . brevicauda Fabricius (p. 141) 



Discal carina low, barely lamellate; ovipositor subhorizontal and longer; upper edge 

 of hind coxa posteriorly very thin, its margin there often serrate; hind femur often 

 mainly black and if more yellow then base and apex yellow (Text-fig. 173) ; in $ 

 gaster basally broader, first tergite transverse ...... 6 



Ovipositor usually exceeding base of gaster, rarely just reaching it; first tergite in § 

 with smooth ovipositorial furrow broad, even anteriorly; scutellum at base 

 broadly black; hind femur with gaps between basal teeth not very broad, 

 puncturation externally moderately coarse . . dorsigera Fabricius (p. 142) 



Ovipositor not quite reaching base of first tergite, often much shorter; ovipositorial 

 furrow on first tergite more or less narrowed anteriorly; scutellum wholly yellow 

 or nearly so ; partly otherwise ......... 7 



Hind femur with gaps between basal teeth narrow (as in dorsigera), puncturation 

 moderately coarse (Text-fig. 175); ovipositor sheaths reaching hind margin of 

 first tergite, median furrow on this tergite from middle distinctly tapering 

 forwards (Boucek, 1959, figs 16-20); Mediterranean . bifasciata Klug (p. 146) 



Hind femur with gaps between basal three teeth very broad, teeth oblique, 

 puncturation externally unusually coarse (Text-fig. 174); ovipositor reaching 

 anterior third of first tergite, its furrow broad even anteriorly; Sudan

Discal carina weak and straight, slightly lower than premarginal carina which may 



be slightly arcuate or angulate ......... 9 



Discal carina very strong, at least as high as the premarginal one and both distinctly 



angulate ............. 10 



Pubescence unusually long although thin ; hind femur slender (Text-fig. 122); pronotal 

 sides converging, concave, shoulders rounded (Text-fig. 121); ovipositor reaching 

 hind fifth of first tergite which has distinct ovipositorial furrow in posterior third ; 

 Sokotra ......... insularis Kirby (p. 106) 



Pubescence short, denser but less thin than in alternate; hind femur fairly broad
