 (Females) 



1 Antennal clava with micropilosity extending over the whole length of its second 



and third segments, and on to the distal half of the first segment. Scutellar 

 frenum shiny, with some longitudinal carinulae, otherwise often nearly 

 smooth. Postspiracular sclerite : oblique carina weak and irregular, or 

 sometimes absent. Fore wing with stigma longer than high, moderate- 

 sized ; wing without a speculum, or with an isolated bare spot below the 

 parastigma. Both mandibles with four teeth . obscurus (Walker) (p. 224) 



— Antennal clava with micropilosity either present on third segment only, or else 



extending at most some way along the second segment as well. Scutellar 

 frenum finely reticulate, with or without longitudinal carinulae. Post- 

 spiracular sclerite : oblique carina often strong and sharp. Fore wing with 

 stigma sometimes differently shaped, or large ; wing never with an isolated 

 bare spot below the parastigma, though most often with a narrow bare line 

 just outside the basal vein. Left mandible sometimes with three teeth . 2 



2 (1) Gaster 2-3 to 3 times as long as broad ; fully as long as, or slightly longer than, 



head plus thorax ; basal tergite occupying at most one third of the total 

 length ; petiole 1-2 to i-6 times as broad as long, subcordiform. Combined 

 length of pedicellus and flagellum hardly greater than breadth of head ; 

 sixth funicular segment quadrate or slightly transverse. Head and thorax 

 black with a very weak bluish or bronze tinge ; antennal scape at least 

 mainly testaceous ..... longiventris Thomson (p. 220)
