2 (i) Median carina of propodeum sharp over at most the anterior quarter of the 



sclerite, behind this effaced and sometimes replaced by a shallow longitudinal 

 furrow ; gastral petiole twice or slightly more than twice as long as broad, 

 tending to narrow slightly caudad ; body dark blue. 



Male antennae with funicular segments, except sometimes the sixth, 

 quadrate to slightly longer than broad. 



Female with first funicular segment quadrate, second only slightly 

 transverse ....... incisus Thomson (p. 139) 



Median carina of propodeum most often complete, sometimes very sharp 

 throughout ; if somewhat effaced in the middle, then the gastral petiole is 

 rather less than twice as long as broad and has more parallel sides (males with 

 incomplete propodeal carina have funicular segments three to six of the 

 antenna transverse). Body of male usually more or less tinged with 

 greenish ; that of female usually with a slight greenish tinge in places, 

 sometimes quite extensively greenish on the thorax .... 3 



3 (2) Male with scutellum distinctly longer than broad, convex ; mesoscutum 



rather strongly convex in front ; lateral angles of pronotum not prominent ; 

 flagellum not pale beneath ; funicular segments, except sometimes the 

 sixth, quadrate to slightly longer than broad. Female unknown . sp. indet. 



Males and females with scutellum nearly or quite as broad as long, nearly flat 

 discally ; mesoscutum weakly convex or rather flat ; lateral angles of 

 pronotum sometimes prominent ; flagellum sometimes pale beneath ; 

 distal segments of funicle sometimes transverse ..... 4 



4 (3) Male has antennal funicle with at most the sixth segment slightly transverse, 



the other segments quadrate (or one to three slightly longer than broad) ; 

 flagellum often reddish beneath ; marginal vein of fore wing 2 to 2-5 times 

 as long as the stigmal vein ; lateral angles of pronotum (Text-fig. 101) 

 more or less prominent except in some dwarf specimens ; tibiae usually 

 testaceous or at most slightly infuscate medially, more heavily so in some 

 dwarfs. Female with first segment of antennal funicle quadrate, second at 

 most very slightly transverse ; fore wing with marginal vein 2-3 to 2-5 

 times as long as the stigmal vein ; tibiae testaceous, or with a moderately 

 broad infuscate band before the middle ; femora usually broadly pale 

 distally ; lateral angles of pronotum tending to be slightly prominent 



incurvus Walker (p. 139) 

 Male with antennal funicle with the first, and sometimes the second, segment 

 quadrate, the remaining segments slightly transverse : flagellum not pale 

 beneath ; marginal vein 1 -6 to 1 -9 times as long as the stigmal vein ; lateral 

 angles of pronotum not prominent (Text-fig. 102) ; tibiae heavily infuscate 

 medially, often mainly black. Female with first segment of antennal 

 funicle slightly, the remaining segments progressively more distinctly, 

 transverse ; marginal vein 1-9 to 2-2 times as long as the stigmal vein ; 

 tibiae heavily infuscate medially, often mainly black, femora black with at 

 most their tips narrowly pale ; lateral angles of pronotum not prominent
