RECLASSIFICATION OF MICROGASTERINI 27 



5 Eyes markedly convergent below (Text-fig. 27). 



Ovipositor sheath at most one and a quarter times longer than the hind tibia . 6 



- Eyes not noticeably convergent below ........ 23 



6 Hind coxa at least in apical half extensively yellow ...... 7 



- Hind coxa virtually blackish throughout . . . . . . . . 13 



7 Median field of tergite (2 + 3) very acutely angled laterally at about 30 degrees and 



itself between four and five times as wide as long (Text-fig. 26). 



Hind coxa in greater part pale yellow with a tongue of infuscation extending 

 forwards on outerside and sometimes almost uniting with a paler, apical spot ; 

 metacarp extremely long and almost closing the radial cell (Text-fig. 22). 

 Philippines ......... lyridice sp. n. (p. 46) 



- Median field of tergite (2 -f- 3) much less acutely angled laterally, its corners angled 



at between 45 and 60 degrees ; the field itself much less transverse ... 8 



8 Hind coxa entirely yellow, faintly shining and without obvious rugosity . . 9 



- Hind coxa with at least a small basal area of infuscation and the outer face with some 



sort of rugosity ............11 



9 Median field of tergite (2 + 3) nearly three times as wide as long, 11:4; ovipositor 



sheath nearer to three quarters as long as the hind tibia. Africa acoris sp. n. (p. 52) 



- Median field of tergite (2 + 3) less transverse, at most hardly more than twice as 



wide as long ; ovipositor sheath nearer to two thirds as long as the hind tibia . 10 



10 Tergite 1 distinctly widened posteriorly ; median field of tergite (2 -f 3) less than 



twice as wide as long, 11:6; dull, rugulose ; dark and pale halves of the hind 



tibia less sharply contrasted. Africa .... meriones sp. n. (p. 52) 



- Tergite 1 not widened posteriorly ; median field of tergite (2 + 3) slightly more 



than twice as wide as long, shiny, almost polished ; dark and pale halves of the 

 hind tibia more sharply contrasted. 



Ovipositor sheath a little shorter than in meriones. Africa . agatillus sp. n. (p. 51) 



1 1 Hind coxa inf uscate only at extreme base ; outer side of hind coxa without rugosity 



except at extreme base. 



Hairy part of the ovipositor sheath hardly more than half as long as the hind 

 tibia ; ovipositor thick, strongly curved (Text-fig. 109) ; hind femur infuscate on 

 apical three fifths ; scape dark ; flagellum thin. Africa . agrus sp. n. (p. 51) 



- Hind coxa much more darkened (but cf. metelhis) ; side of hind coxa considerably 



rugose. 



Hind femur bright yellow on at least nearly basal half . . . . 12 



12 Hind leg strikingly black and yellow ; hind coxa yellow on almost apical half ; hind 



femur sharply brown on rather more than apical half ; median field of tergite 

 (2 + 3) less transverse, its lateral sulcus almost as long as its basal width ; head 

 thicker, with temples somewhat produced backwards ; tergite (2 + 3) beyond the 

 median field, yellow. Africa ...... menes sp. n. (p. 51) 



- Hind leg less strikingly bicoloured ; hind coxa usually almost black but sometimes 



infuscate only at extreme base ; hind femur infuscate only at apex and then more 

 especially above ; median field of tergite (2 + 3) more transverse, a lateral sulcus 

 equal to hardly more than two thirds the basal width ; head less thick ; tergite 

 (2 + 3) beyond the median field entirely dark. 

 Ovipositor sheath slightly longer than in menes. Africa metellus sp. n. (p. 50) 



13 Ovipositor sheath at most as long as the hind tibia . . . . . . 14 



- Ovipositor sheath at least slightly longer than the hind tibia .... 22 



14 Punctures at posterior end of the imaginary course of the notaulices very large, more 



or less discrete and without longitudinal elements here ; the surface between 

 the punctures very shiny ; hind tibia dark brown but sharply whitish on basal two 

 fifths.
