RECLASSIFICATION OF MICROGASTERINI 33 



scutellum with a few, large, ill defined pits or punctures ; tergite 1 hardly- 

 narrowed to apex. Fiji Is. . . . . . hymeniae Wilkinson (p. 86) 



- Hind coxa blackish ; median field of tergite (2 + 3) faintly dull, with scattered, obsol- 



escent punctures ; disc of scutellum confusedly punctate ; tergite 1 quite strongly- 

 narrowed to apex. Malaya ...... medon sp. n. (p. 90) 



40 Ovipositor sheath not or hardly longer than the hind basitarsus . . . . 41 



- Ovipositor at least distinctly longer than the hind basitarsus, usually much longer . 47 



41 Tergite 1 abruptly narrowed from where it turns over to apex, the median field of 



tergite (2 + 3) hence very sharply angled laterally at less than 45 degrees and a 

 lateral sulcus fully equal to the apical width of tergite 1 ; areolation of propodeum 

 reduced or almost absent. 



Metacarp not more than four times as long as its distance from the apex of the 

 radial cell ............. 42 



- Tergite 1 only slightly narrowed posteriorly or, if strongly so, then the areolation of 



the propodeum is complete .......... 43 



42 Costula of propodeum present ; tergite 1 beyond the median field setose all over ; 



stigma evenly brownish ; ovipositor sheath so short as to be virtually concealed ; no 

 angle between the 1st abscissa of the radius and the transverse cubitus ; tergite 1 

 rugose. Malaya ........ prosymna sp. n. (p. qS) 



- Costula absent ; tergite 1 beyond the median field with its setae reduced and more 



or less restricted to a row along apical margin ; stigma pallid or at most pale 

 brownish with a darker border ; ovipositor sheath projecting more freely than 

 above ; tergite 1 almost smooth, highly polished. Indo-oriental region 



javensis Rohwer (p. 98) 



43 1st abscissa of the discoideus forming with the nervulus virtually a straight line. 



Temples very coarsely rugose ; disc of scutellum with large punctures along 

 sides ; tergite 1 short, more or less parallel-sided ...... 44 



- 1st abscissa of the discoideus forming with the nervulus an angle at their junction . 45 



44 Stigma pallid ; costula very sharply defined. Indo-oriental region folia sp. n. (p. 99) 



- Stigma evenly dark brown ; costula more or less wanting . . folia var.? (p. 99) 



45 Segment 4 of the hind tarsus, measured below, very distinctly shorter than 5 ; meta- 



carp rather short, about three times as long as its distance from the apex of the 

 radial cell ; hind wing broad, the 2nd abscissa of the mediella being very distinctly 

 shorter than the distance between its distal extremity and the apex of the vannal 

 lobe. Malaya ........ demades sp. n. (p. 99) 



- Segment 4 of the hind tarsus hardly shorter than 5 ; metacarp fully six times as long 



as its distance from the apex of the radial cell ; hind wing narrower, the 2nd 

 abscissa of the mediella being less obviously shorter than the distance between its 

 distal extremity and the apex of the vannal lobe ...... 46 



46 Wings not markedly hyaline, the setae dark and the stigma not very pale ; median 



field of tergite (2 + 3) about two and a half times wider than long (Text-fig. 86) ; 

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

 hind basitarsus. Philippines ...... crates sp. n. (p. 100) 



- Wings markedly hyaline, the setae, at least proximal to the areolet, virtually 



colourless ; median field of tergite (2 + 3) fully four times as wide as long and 

 acutely angled laterally ; inner spur of the hind tibia weak, hardly reaching the 

 middle of the hind basitarsus. Philippines . . . sartamus sp. n. (p. 100) 



47 Ovipositor sheath much shorter than the hind tibia. 



Small spp. ca. 2 mm. without ovipositor ....... 48 



- Ovipositor sheath at least about three quarters as long as the hind tibia . . 52 



48 Stigma pallid with a faintly darker border ....... 49 



- Stigma evenly brown. 



Mesoscutum very shiny in spite of its strong punctation ; distance between the
