22 Lateral third of propodeum in far greater part without raised rugosities, the surface 



with dull microsculpture which has a satin-like sheen ; disc of scutellum, except 

 narrowly along sides, smooth, shining ; at least the apical half of the hind tibia

— Lateral third of propodeum with numerous, raised rugosities, the surface very shiny 



and without a satin-like sheen ; disc of scutellum somewhat dull by reason of vague

 quite reaching to middle of hind basitarsus ; antenna rather short, with the pre- 

 apical segment about one and one third times longer than wide ... 25 



- Ovipositor thick, evenly downcurved throughout but not strongly so . . . 26 



25 Ovipositor more abruptly downcurved at apex ; ovipositor sheath narrower (Text- 



fig. 161 ) ; claws of hind tarsus less well developed ; hypopygium less well 

 developed and less strongly sclerotised ..... oscus sp. n. (p. 116)

thicker ; claws of the hind tarsus more strongly developed ; hypopygium more 

 strongly developed, longer, more heavily sclerotised (Text-fig. 92) 



olorus sp. n. (p. 117) 



26 Ovipositor slightly less thick ; fore wing with more pigmentation, at least the 1st and 



2nd abscissae of the discoideus and the nervulus fully pigmented ; stigma dark, 

 only faintly paler medially ; tergite 1 more strongly narrowed behind ; antenna

sculpture at the posterior end of the notaulic courses ; antenna very short, about
