RECLASSIFICATION OF MICROGASTERINI 125 



Inner spur of the hind tibia only slightly longer than the outer one. 



Spp. with the fore wing less conspicuously dappled ; hind tibia less spinose and 

 lacking a prickly appearance ......... 3 



Middle third of flagellum orange-yellow ; dark, proximal cloud of the fore wing filling 

 almost half the median cell, the darkened area densely setose ; apex of fore wing 

 with a dark cloud ; cheeks and temples with a duller, more obvious sculpture of 

 contiguous punctation ; mesoscutum in front with an overlay of delicate surface 

 sculpture and with a satin-like sheen ; propodeum posteriorly and especially around 

 the orifice and along the middle deeply scored with coarse rugosities ; hind femur 

 black to almost red ; hind tarsal segment 1 black and contrasting with the remaining 

 segments which are orange-yellow ; middle part of the face reddish like the scape ; 

 ovipositor sheath only slightly longer than the hind tibia. 



Tergite (2 + 3) yellowish-orange to a variable extent . trifasciatus Muesebeck 2 



Hawaii, Honolulu, type locality. Fiji Is., Viti Levu, 27. xi. 1956, 1 $, labelled 

 "on coconut-palm-leaf" ; Cicia, Lau, 5.xi.iQ45, 1 $, (R. A. Lever). Type in U.S. 

 National Museum. 



Host : Type material recorded by Muesebeck as having been bred from cotton bolls. 

 Flagellum black throughout ; proximal cloud of the fore wing much smaller, filling 

 only about distal sixth of the median cell ; the clear part of the median cell is almost 

 without setae (Text-fig. 112) ; apex of the fore wing without a dark cloud ; cheeks 

 and temples more shiny and with a much more superficial sculpture ; punctation of 

 the mesoscutum finer, the microsculpture and the punctures less contrasted ; coarse 

 sculpture of the propodeum less abundant and restricted more or less to the middle 

 line ; sides of propodeum hence more extensively smooth than in trifasciatus ; hind 

 femur entirely black ; only the apical 2-3 segments of the hind tarsus pale ; face 

 black ; ovipositor sheath a little longer, fully one and a quarter times longer than 

 the hind tibia .......... orphne sp. n. 



Fiji Is.: Nadala, 11. x. 1942, 1 $, the TYPE ; Lami, 19. iv. 1945, 1 $, 1 <J, labelled 

 "on Zea mays" , (R. A. Lever). Type in the British Museum (Nat. Hist.). 



In this species, the 1st abscissa of the discoideus is almost as long as the 2nd ; in 

 trifasciatus it is very distinctly shorter. Both species have the base of the radius 

 distinctly indicated as a short, sclerotised stub. The relationship between the two 

 species is close ; I can suggest no affinity with any particular section of the ater- 

 group. 

 Mesoscutum with large punctures that are crowded on the anterior, declivous part but 

 posteriorly become widely separated and on about posterior half tend to fade out 

 completely, leaving the surface highly polished and strikingly bare ; edge of vannal 

 lobe almost evenly convex throughout and with distinct hair-fringe ; propodeum 

 along middle with large, rugulose trough ; towards the front, between this trough 

 and the spiracle, the surface is highly polished ; propodeum a little longer than in 

 the other species and with very prominent, posterior corners ; ovipositor sheath 

 about one and a half times longer than the hind tibia. 



Mesopleurum with long, wide, deep furrow that is distinctly rugoluse ; length : 

 ca. 2. 3 mm. without ovipositor ....... cyane sp. n.

 1 $, ex Agonoxena argaula Meyrick, (R. W . Paine). Type in the British Museum 

 (Nat. Hist.). 



This is a much more slenderly built species than the others. The smooth parts of 

 the body are polished and completely lack the satin-like sheen characteristic of the 

 other species. The two clouds of the fore wing are much less well developed and 

 both wings are narrower. The flagellum is imperceptibly thickened in about apical 

 quarter and the two preapical segments are as long as wide.
