RECLASSIFICATION OF MICROGASTERINI 223 



Hypomicrogaster laurae (de Saeger) comb. n. 

 Microgaster laurae de Saeger, 1944 : 61. 



I am confident that I have interpreted this species correctly, though the S. African 

 specimens I have examined are all darker in colour than those described by de 

 Saeger. 



j Hind coxa entirely yellow ; hind femur yellow but darkened along upper surface towards 

 apex ; hind tibia and hind tarsus entirely brown. Body dark brown with the gaster yellowish 

 beneath. Wings markedly smoky. 



Ocelli in rather a low triangle, the transverse posterior tangent to the anterior ocellus virtually 

 touching the posterior pair. Flagellum distinctly thickened towards apex, with segments 15-17 

 about one and third times longer than wide. Face with large, shallow punctures. 



Mesoscutum densely, more or less contiguously punctate everywhere. Radius Leaving stigma 

 far distal to middle (Text-fig. 275) ; transverse cubitus more or less interstitial with 1st abscissa 

 of radius ; vannal lobe with long fringe throughout. 



Tergite 1 turned over far anterior to middle, dull, densely, finely rugose all over (Text-fig. 278). 

 Ovipositor sheath about three quarters as long as the hind tibia. 



Belgian Congo : Rwindi (type locality). S. Africa : Cape Province, Katberg, 

 5 $$, ; Zululand, Eshowe, 1 $ ; Pondoland, Port St. John, 1 $. 



Type in Congo Museum, Tervuren. 



This species was described by de Saeger as red testaceous. Of the specimens I 

 have before me, only the female from Eshowe is intermediate in colour, having the 

 head, mesoscutum and scutellum pale brown and the underside of the gaster more 

 brightly yellowish than in the other S. African specimens. 



This is a most distinct species on account of the pale banded flagellum and the 

 shape of the first tergite. No other species in the group has either of these features. 



Hypomicrogaster fomes sp. n. 



$. Gaster entirely reddish-yellow except that the apex of tergite 1 and the median field of 

 tergite (2 -\- 3) are darkened ; there is also slight medial infuscation on the following tergites. 

 Hind coxa entirely yellow ; hind femur and hind tibia tipped with infuscation ; hind basitarsus 

 pale at base. Wings very faintly tinted. 



Face shiny and with hardly a trace of punctation. Ocelli not in a low triangle, the posterior, 

 transverse tangent to the anterior ocellus not touching the posterior pair ; distance between the 

 posterior ocelli twice the diameter of the anterior ocellus. Antenna rather thin, a little shorter 

 than the body, tapering somewhat towards apex and with the preapical segment about one and 

 one third times longer than wide. 



Mesoscutum with slight satin-like sheen ; with only very fine, superficial punctation. The two 

 fields of the propodeum highly polished. Areolet distinctly four-sided ; vannal lobe beyond its 

 widest part with faint indication of a hair-fringe. 



Tergite 1 quite strongly narrowed behind, its horizontal surface showing a few irregular 

 rugosities. Ovipositor sheath a little shorter than the hind tibia. 



Length: ca. 2-8 mm. without ovipositor. 



S. Africa : Cape Province, Katberg, 1-10.ii.1933, 1 $, the TYPE, (R. E. Turner) ; 

 Transkei, Umtata, 18.ii.-18.iii.1923, 1 $, (R. E. T.). 



Type in the British Museum (Nat. Hist.). 



The dark and pale parts of the colour of the hind leg are somewhat sharply con- 

 trasted in this species.
