RECLASSIFICATION OF MICROG ASTERINI 213 



Key to Species 

 Females 



Whole body virtually entirely reddish-yellow with only the head black and the gaster 



with some dark markings apically ......... 2 



At least the propodeum and the 1st tergite blackened ...... 3 



Ovipositor sheath fully as long as the hind tibia ; mesoscutum, especially posterior to 

 the tegulae, very narrowly margined with black. 



Head blackish with the clypeus yellowish ; fore wing faintly darkened distal to 

 the areolet ; tergites 4-6 with a brown band ; the bands widen medially, leaving on 

 each side of the gaster a transverse yellow mark ; inner spur of the middle tibia very 

 powerful, very distinctly longer than the middle basitarsus ; gaster rather more 

 elongate than in the other species ; tergite 1 highly polished and with a few, large, 

 shallow pits ............ ecus sp. n. 



Brazil: Nova Teutonia, 29.vi.1938, 1 $, the TYPE, (Plaumann) . Type in the 

 British Museum (Nat. Hist.). 

 Ovipositor sheath hardly three quarters as long as the hind tibia ; mesoscutum 

 entirely reddish-yellow. 



Head missing, but black according to Ashmead, except face ; wings hyaline ; 

 median cell of fore wing very sparsely hairy (setae rubbed off ?) ; propodeum with 

 well defined areola and equally well defined, postero-lateral areas ; the areola is 

 divided into two parts by a longitudinal keel, a condition more or less typical of the 

 group ; tergite 1 very distinctly widened behind, its horizontal surface with scat- 

 tered, deep pits ; these are much more obvious than in ecus . imitator (Ashmead) 37 

 Thorax blackish, at most with a pale spot at each posterior corner of the mesoscutum . 4 

 Thorax reddish-yellow or at least testaceous with darker suffusion posteriorly. 



Hind coxa entirely yellow .......... 7 



Median field of tergite (2 + 3) twice as wide as long (Text-fig. 268) ; tergite 1 narrow, 

 fully twice as long as wide, polished and with hardly a trace of punctation. 



Hind coxa entirely yellow ; mesoscutum with pale spot at each posterior corner ; 

 median field of tergite (2 + 3) and most of the segment posterior to the field, bright 

 reddish-yellow ; ovipositor very short, about half as long as the hind tibia 



acarnas sp. n. 

 Brazil: Nova Teutonia, 11. v. 1938, 1 $, the TYPE, (Plaumann). Type in the 

 British Museum (Nat. Hist.). 

 Median field of tergite (2 + 3) always more transverse than this, fully three times as 

 wide as long ; tergite 1 shorter, less narrow and with more punctation or rugose- 

 punctation on its horizontal part ......... 5 



Hind coxa entirely yellow ; inner spur of the middle tibia weaker, not longer than the 

 middle basitarsus. 



Tergite 1 quite strongly narrowed behind ; ovipositor sheath about two thirds as 

 long as the hind tibia ; wings clear hyaline ; tergite (2 + 3) yellow or testaceous
