RECLASSIFICATION OF MICROGASTERINI 105 



coideus darkened and pigmented ; inner spur of the hind tibia not quite reaching 

 the middle of the hind basitarsus. 



Stigma evenly dark brown . . . . . . . . . 10 



- Eyes hardly convergent below and hence wider apart on the face ; 1st and 2nd 



abscissae of the discoideus not obviously darkened or pigmented ; inner spur of 

 the hind tibia reaching middle of hind basitarsus and longer compared with the 

 outer spur than above. 



Antenna shorter than the body, with the preapical segment about one and one 

 quarter times longer than wide ......... 12 



10 Tergite 1 virtually parallel-sided. 



Antenna as long as the body, very thin, rather abruptly narrowed beyond seg- 

 ment 13 ......... . dido sp. n. (p. 112) 



- Tergite 1 distinctly narrowed apically . . . . . . . . n 



1 1 Antenna shorter, the preapical segment hardly one and one third times longer than 



wide ; setae of the radial cell becoming noticeably sparser towards the stigma ; 

 tergite 1 narrower only at extreme apex ; mesoscutum appearing slightly blacker 

 because its sculpture is less obscured by pubescence . . ione sp. n. (p. in) 



- Antenna longer, the preapical segment about one and a half times longer than wide ; 



setae of the radial cell not becoming so noticeably sparser towards the stigma ; 

 tergite 1 narrowed from where it turns over to apex and with a narrower, deeper 

 trough on its horizontal part ; mesoscutum appearing less black owing to a finer, 

 denser pubescence ........ t riareus sp. n. (p. 112) 



12 Ovipositor sheath as long as the hind tibia and, seen from above, clothed with long, 



upstanding hairs ; tergite 1 almost coarsely rugose, not or hardly narrowed 

 behind ; stigma dark, with or without a still darker border ; metacarp slightly 

 longer .......... eupoli s sp. n. (p. m) 



- Ovipositor sheath longer than the hind tibia, about one and one third times longer 



and, seen from above, with short, not upstanding hairs ; tergite 1 only very weakly 

 rugulose, distinctly narrowed behind ; stigma pallid with contrasting darker 

 border ; metacarp slightly shorter . ..... navius sp. n. (p. 111) 



13 Ovipositor sheath at most one and a half times longer than the hind tibia . . 14 



- Ovipositor sheath almost twice as long as the hind tibia ..... 29 



14 Metacarp short, at most only slightly more than twice as long as its distance from 



the apex of the radial cell. 



Stigma colourless, with darker border ; ovipositor moderately thick . . 15 



- Metacarp longer, at least three times as long as its distance from the apex of the radial 



cell 18 



15 Mesopleurum pubescent all over, at most a very small bare zone in front of the middle 



coxa ; mesoscutum with a very characteristic dense, silvery, pubescence that, on 

 posterior half of the mesoscutum, becomes longer and more silky. 



Eyes not convergent .......... 16 



- Mesopleurum with a large, oblique zone that is completely free from hairs ; 



pubescence of the mesoscutum shorter, of normal appearance . . . . 17 



16 Tegula ivory-white ; ovipositor sheath as long as the hind tibia, not at all falcate 



apically .......... a rticas sp. n. (p. 112) 



- Tegula pale brown ; ovipositor sheath fully one and a quarter times longer than the 



hind tibia, markedly falcate apically ..... mutilia sp. n. (p. 113) 



1 7 Ovipositor sheath hardly as long as the hind tibia ; eyes distinctly convergent ; inner 



spur of the hind tibia rather weak, not reaching beyond the middle of the hind basi- 

 tarsus .......... lycida s sp. n. (p. 113) 



- Ovipositor sheath distinctly longer than the hind tibia ; eyes virtually not convergent ; 



inner spur of the hind tibia stronger, reaching distinctly beyond the middle of the 

 basitarsus. Philippines ....... upis sp. n. (p. 117)
