Hind femur yellow except for faint apical infuscation ; hind tibia sharply 

 blackened at tip ; disc of scutellum thickly punctate, the punctures smaller to- 

 wards sides. Mauritius ...... agamedes sp. n. (p. gi) 



- Propodeum without complete areolation, the costula not or hardly distinguishable 



from the surrounding rugae ; vannal lobe beyond its widest part at first sight 

 bare, at most with widely separated, minute, projecting hairs. 



Mesoscutum with dull, densely rugose sculpture and without longitudinal 

 elements at the posterior end of the notaulic courses ..... 96 



96 Hind femur bright yellow but becoming infuscate towards apex above ; ovipositor 



sheath shorter, nearer to one and one third times longer than the hind tibia ; 

 mesopleurum with a more sharply defined, more extensively rugose sternaulus ; 

 hind tibia with more extensive apical infuscation ; edge of vannal lobe with an 

 occasional projecting hair. Africa ..... anatole sp. n. (p. 54) 



- Hind femur reddish-yellow with only the merest trace of apical infuscation ; ovi- 



positor sheath longer, nearer to one and half times longer than the hind tibia ; 

 mesopleurum with a less sharply discrete, less rugose sternaulus ; hind tibia 

 infuscate only at extreme apex ; edge of vannal lobe without trace of projecting 

 hairs. Africa ......... racilla sp. n. (p. 55) 



97 Antenna exceptionally short, hardly longer than head plus thorax and with segments 



12-17 almost transverse. 



Areolation of the propodeum incomplete, the costula wanting ... 98 



- Antenna never as short as this, at least segment 12 being clearly longer than wide . 99 



98 A brownish cloud beneath the stigma ; ovipositor sheath about two thirds as long as 



the hind tibia ; ovipositor with abrupt apical constriction (Text-fig. 67) 

 Sumatra ......... aglaope sp. n. (p. 61) 



- No such cloud beneath the stigma ; ovipositor sheath much longer than the hind 



tibia ; ovipositor without an obvious apical constriction. Africa 



adreus sp. n. (p. 61) 



99 Ocelli in a high triangle, the transverse, posterior tangent to the anterior ocellus not 



touching the posterior pair. 



Hind wing narrow; areolation of propodeum incomplete or more or less wanting 100 



- Ocelli in a low triangle, the posterior tangent to the anterior ocellus cutting or, at any 



rate, virtually touching the posterior pair ....... 103 



100 Propodeum dull, densely rugose all over and without areolation, there being no 



smoothing of the surface to indicate the posterolateral areas and hardly a trace of 

 an areola ; hind femur yellow ; face dull, sharply punctate. 

 Tergites (2 + 3)-6 thickly hairy all over. Queensland . aper sp. n. (p. 62) 



- Propodeum much less dull, the postero-lateral areas being more or less indicated by 



a fading out of sculpture and the areola sharply defined ; hind femur blackish or 

 brownish ; face shiny, impunctate ........ 101 



101 Tergites (2 + 3)-6 with hairs reduced more to less to a single row ; abscissa 1 of the 



radius more or less at right angles to the stigma ; mesopleurum without rugose 

 sternaulus ; hind femur virtually black ....... 102 



- Tergites (2 + 3)-6 hairy all over ; abscissa 1 of the radius very obliquely placed on 



the stigma ; mesopleurum with wide, trough-like sternaulus filled with irregular 

 striation ; hind femur brown. Africa .... parsodes sp. n. (p. 60) 



102 Ovipositor sheath markedly longer than the hind tibia ; cubitellan cell of the hind 



wing longer, more or less parallel-sided ; antenna longer, segment 14 being about 

 twice as long as wide. Queensland ..... vala sp. n. (p. 62) 



- Ovipositor sheath hardly as long as the hind tibia ; cubitellan cell of the hind wing 



shorter, distinctly narrowed apically ; antenna shorter, segment 14 being about 



one and one third times longer than wide. Queensland . fundulus sp. n. (p. 64) 



103 Tergite 1 long, narrow, strongly narrowed distally, its horizontal part at least one
