 like the mesoscutum ; ovipositor sheath very slightly longer than the hind tibia. 

 Morocco .......... semele sp. n. (p. 224) 



Mesoscutum pale on posterior half, the pale colour extending forwards along the 

 course of the notaulices. 



1st abscissa of the discoideus distinctly shorter than the 2nd ... 6 



Mesoscutum black or very dark brown with faint reddening posteriorly . . 7 



Tergite 1 entirely reddish-yellow ; areolet of the fore wing 3-sided ; head more 



transverse (Text-fig. 272). Uganda . . . vacillatrix Wilkinson (p. 224) 



Tergite 1 black ; areolet of the fore wing distinctly 4-sided ; head less transverse. 



S. Africa .......... apollion sp. n. (p. 224) 



Tergite 1 bright yellow, very strongly narrowed behind ; pronotal collar yellow and 



sharply contrasting with the dark brown mesoscutum. India . irates sp. n. (p. 225) 



Tergite 1 darkened at least apically and then it is not so strongly narrowed behind as 



in irates ............. 8 



Ocelli forming virtually an equilateral triangle, the distance betweeen the posterior 

 pair hardly less than the diameter of the median ocellus. 



Thorax pale, its sides conspicuously reddish ; hind femur yellow ; hypopygium 

 evenly sclerotised almost all over and with hardly a trace of lateral creases. Sierra 

 Leone .......... helle sp. n. (p. 225) 



Ocelli not forming an equilateral triangle, the distance between the posterior pair at 



least slightly greater than the diameter of the median ocellus .... 9 



Hind femur black. 



Tergite 1 not abruptly, roundly narrowed behind . . . . . 10 



Hind femur yellow or if infuscate, then tergite 1 is abruptly roundly, narrowed behind. 

 Wings brownish ; areolet distinctly 4-sided ; vannal lobe with a conspicuous 

 fringe of hairs ............11 



Stigma unusually broad (Text-fig. 271), without a pale proximal blotch ; antenna as 

 long as the body and of ordinary form ; ovipositor sheath fully as long as the hind 

 tibia. Europe. Mediterranean region . . . . sufiolciensis Morley (p. 228) 



Stigma of ordinary form but with a pale proximal blotch ; antenna shorter than the 

 body, very thin, the apical segments very closely articulated and having a smooth, 

 shiny appearance ; ovipositor sheath about three quarters as long as the hind tibia. 



Tergite 1 hardly narrowed behind. Europe . . . tiro Reinhard (p. 229) 



Antenna distinctly thickened apically, with segments 15-17 about one and one third 

 times longer than wide ; face markedly paler than the top of the head ; mesoscu- 

 tum dark brown with faint reddish flush behind and along the course of the notauli- 

 ces ; antenna in a low triangle. S. Africa . . . gerontius sp. n. (p. 226) 



Antenna not at all thickened apically, segments 15-17 being nearer to one and a half
