RECLASSIFICATION OF MICROG AST E RI X I _ M3 



of tergite 2 less well defined ; lateral areas with faintly indicated surface sculpture. 



Tergite i at apex with deep excavation but not smoothly hollowed out ; surface 

 on each side of excavation less swollen, coarsely rugose ; areolet as in pyrene 

 (cf. Text-fig. 310) ......... seriphussp.n. 



Philippines: Los Banos, 1 $, the TYPE, 1 $, Luzon, Mt. Makiling, 1 <J, (all 

 Baker). Type in the U.S. National Museum. 

 Tergite 3 only slightly wider apically than its median length, hence only slightly 

 transverse ; the three delimited fields of tergite 2 slightly longer and highly 

 polished. 



Mesoscutum varying from red through dusky red to almost black ; claws without 

 a comb ........... pyrene sp. n. 



Tergite 3 much wider than medially long, nearly twice as wide ; the three fields of ter- 

 gite 2 shorter and with clear indication of surface sculpture, 



Mesoscutum bright reddish ; the thorax is almost entirely reddish above, the pale 

 colour extending backwards as far as the anterior surface of the propodeum ; tergite 

 1 and most of 3 reddish (see couplet 3) ..... . seriphus sp. n. 



A single male that I also refer to this species (Mt. Makiling) differs from the typical 

 form in having the entire thorax and the dorsal surface of the gaster blackish, with 

 the mesoscutum more shiny and less obviously punctate posteriorly. 

 Eyes very large, slightly convergent above, separated from the posterior ocellus by a 

 distance not greater than the diameter of the ocellus. 



Tergite 1 only about one and half times to one and two thirds times as long as its 

 middle width ; tergite 2 sharply divided into three areas by deep furrows ; 

 ovipositor with a pale, apical setiform appendage ...... 6 



Eyes not as large as this, slightly divergent above and separated from the posterior 

 ocellus by a distance very distinctly greater than the diameter of the ocellus. 



African and S. American spp. 

 First abscissa of the radius very long, meeting the 2nd transverse cubitus (itself a mere 

 hyaline spot) at the junction of the 2nd abscissa of the radius. 



Thorax almost black ; hind coxa reddish-yellow ; face reddish with fairly 

 strong rugose-punctation along each side ..... urios sp. n. 



Borneo : Sandakan, 1 $, the TYPE, (Baker). Type in the U.S. National Museum. 



Easily distinguished from the next two species by the long 1st abscissa of the 

 radius. 

 First abscissa of the radius much shorter, not uniting with the 2nd transverse cubitus ; 

 2nd transverse cubitus meeting the 1st far proximal to the junction of the two 

 abscissae of the radius ........... 7 



Hind coxa bright yellow ; mesoscutum yellow with faint infuscate spot at shoulder ; 

 2nd transverse cubitus virtually not indicated, hence no areolet ; 1st transverse 

 cubitus curiously thickened (Text-fig. 308). 



The narrow, yellow face shows only a very superficial sculpture . tnelleus sp. n. 



Philippines: Luzon, Mt. Makiling, 2 9?. one the TYPE, (Baker). 

 Type in U.S. National Museum. 



A male from Los Banos has the mesoscutum reddened, with the lateral lobes 

 faintly darker and the hind coxa not such a bright yellow ; the venation is like that 

 of the female. 

 Hind coxa deeper in colour, reddish-yellow ; mesoscutum entirely infuscate, though 

 becoming paler posteriorly ; 2nd transverse cubitus distinct, the areolet hence 

 clearly indicated ; 1st transverse cubitus not thickened. 



Face reddish, slightly less narrow than in niellens and its surface more shiny and 

 smoother ........... medon sp. n. 



Philippines: I. of Basilan, 1 9. the TYPE, 1 3, (Baker). Type in the U.S. 

 National Museum.
