RECLASSIFICATION OF MICROGASTERINI 225 



Hypomicrogaster irates sp. n. 



$. Head and thorax dark brown ; gaster dark brown beyond tergite 1 in the type series ; 

 almost entirely yellow in other females. Hind femur darkened at extreme tip ; hind tibia 

 becoming infuscate on about apical third. Wings hyaline ; stigma with a faintly paler proximal 

 spot. 



Face very shiny, impunctate. Distance between the posterior ocelli hardly greater than the 

 diameter of the median ocellus. Antennal almost as long as the body, fairly thick but slightly 

 tapered towards apex ; flagellum somewhat bristly. 



Mesoscutum very shiny and with at most a very superficial punctation. The two fields of the 

 propodeum highly polished. Areolet distinctly four-sided ; 1st abscissa of the discoideus very 

 slightly shorter than the 2nd ; vannal lobe with distinct hair-fringe throughout. Hind spurs 

 whitish, the inner one much longer than the outer one and reaching distinctly beyond the middle 

 of the hind basitarsus ; longer spur of the middle tibia reaching slightly beyond the apex of the 

 middle basitarsus. 



Tergite 1 strongly narrowed behind, its sides on the horizontal part straight (Text-fig. 277). 

 Ovipositor sheath hardly more than two thirds as long as the hind tibia. 



Length: 2-5 mm. without ovipositor.

 TYPE (9, 2.x. 1942) from Hapalia machaeralis defoliating Tectona grandis ; Dehra 

 Dun, (1 $, bred 28. ix. 1943, from H. machaeralis, 2 $$, 2 <&£, bred 28.vii.-4.viii.1934 

 from Sylepta lunalis defoliating Leea aspera. 



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



Host : Hapalia machaeralis Walker ; Sylepta lunalis Guenee (Pyraustidae). 



This species is superficially very like the African fomes differing from it most 

 obviously in colour. Nevertheless, because the 1st abscissa of the discoideus is 

 shorter than the 2nd in irates, I am inclined to think that it is more closely related 

 to vacillatrix than to fomes, which has these abscissae of equal length. The affinities 

 of fomes are, I think, with suffolciensis and tiro rather than with vacillatrix and irates. 



Hypomicrogaster helle sp. n. 



$. Mesoscutum very dark brown to black ; disc of the scutellum slightly paler ; tergite 1 

 pale on anterior declivous part but becoming darkened on posterior horizontal part ; the under- 

 side of the gaster is bright reddish-yellow. Antenna yellowish beneath. Legs entirely yellow 

 except that the hind tibia becomes infuscate on about apical third and the hind basitarsus is 

 more or less infuscate all over. 



Head in a facial view somewhat subtriangular (Text-fig. 282). 



Face shiny, virtually impunctate. Antenna as long as the body, rather weak, slightly tapered 

 apically, the preapical segment about one and one third times longer than wide ; flagellum 

 markedly bristly. 



Mesoscutum with fairly distinct punctation on anterior half. The two fields of the propodeum 

 smooth, shining. Areolet four-sided ; 1st abscissa of the discoideus distinctly a little shorter 

 than the 2nd ; vannal lobe with distinct hair-fringe throughout. 



Tergite 1 rather short, not much narrowed behind (Text-fig. 285). Median field of tergite 

 (2 -)- 3) with weak rugosity similar to that of the horizontal part of tergite 1. Ovipositor sheath 

 a little shorter than the hind tibia. 



Length: ca. 2.5 mm. without ovipositor.
