sculpture fine and that within the median hollowed out part on horizontal surface 

 almost scaly-reticulate ; propodeum with fine, dull, even sculpture ; areola 

 hardly defined. India ..... angaleti Muesebeck (p. 76) 



- Thicker spines along the upper part of outer side of hind tibia strong, sharp, densely 



crowded ; disc of scutellum narrower behind ; tergite 1 hardly narrowed behind ; 

 propodeum smoother, more shiny. Philippines . . nephereus sp. n. (p. 76) 



66 Entire head, including a large area immediately behind the ocelli dull and appearing 



greyish owing to excessively fine pubescence superimposed on a fine rugosity ; 

 mesoscutum completely dull owing to extremely fine, dense, rugose-punctation ; 

 disc of scutellum flattened and rather wide behind with somewhat coarse, uneven 

 punctation. Philippines ....... cebes sp. n. (p. 80) 



- Head of ordinary appearance and shiny black though with distinct rugosity at 



temples ; mesoscutum not so evenly dull as this ; disc of scutellum polished 

 except for faint trace of sculpture along sides ...... 67 



67 Tergite 1 hardly narrowed behind, almost parallel-sided ; ovipositor not, or hardly, 



longer than the hind tibia .......... 68 



- Tergite 1 very distinctly narrowed behind (not so much in murcia) ; ovipositor sheath 



at least about one and a quarter times longer than the hind tibia ... 69 



68 Ovipositor sheath distinctly longer than the hind tibia ; spines along upper part of 



outer side of hind tibia more numerous, closer ; distance between the posterior 

 ocelli not greater than the distance between one of them and the eye-margin. 

 India ........ tachardiae Cameron (p. 72) 



- Ovipositor sheath not longer than the hind tibia ; spines along upper part of outer 



side of hind tibia sparser, finer, less close ; distance between the posterior ocelli 

 distinctly greater than the distance between one of them and the eye-margin. 

 India ........ machaeralis Wilkinson (p. 72) 



69 Propodeum on each side of the areola polished, smooth, there being no trace of an 



areola or keel behind the spiracle ; ovipositor sheath about one and a quarter 

 times longer than the hind tibia. India . . importunus Wilkinson (p. 73) 



- Propodeum on each side of the areola (this often poorly defined) with rugosity at 



least in the place normally occupied by the costula ; ovipositor sheath fully one 



and one third times longer than the hind tibia ...... 70 



70 Upper part of the convexity of the mesopleurum with more distinctly discrete 



punctation on a polished, smooth surface ; face very distinctly but rather finely 

 punctate ; ovipositor very thin ; horizontal part of tergite 1 longer than wide. 

 India .......... oritias sp. n. (p. 68) 



- Upper part of the convexity of the mesopleurum with coarse rugose-punctation on a 



rather dull surface ; face much less distinctly punctate ; ovipositor a little 

 thicker ; horizontal part of tergite 1 slightly transverse. Malaya 



murcia sp. n. (p. 73) 



71 Temples shiny, almost smooth. 



Antenna about as long as the body ; hind wing narrow ; propodeum with com- 

 plete, sharp areolation ; tergite 1 long, narrow ...... 72

72 Hind tibia and hind tarsus evenly brownish ; spines of the outer side of the hind tibia 



virtually not differentiated into two types and all of them sparse ; hind spurs 

 rather short, the inner one hardly longer than the outer one ; ovipositor sheath 

 fully as long as the hind tibia ; vannal lobe not concave, its edge with an 

 occasional projecting hair (Text-fig. 15) ; head deep from back to front. 

 Philippines ......... saravus sp. n. (p. 81) 



- Hind tibia yellowish on more than basal half ; hind basitarsus yellowish at base ; 



spines of the outer side of the hind tibia differentiated into two types, much denser 

 then in saravus ; hind spurs longer, the inner one much longer than the outer one ;
