208 G. E. J. NIXON 



Head smooth, shining. Mesoscutum smooth, shining, its pubescence rather conspicuous. 

 Suture between the disc of the scutellum and the mesoscutum very shallow, inconspicuous. Pro- 

 podeum with a certain amount of rugosity towards sides and more especially around the spiracle. 

 Mesopleurum with a deep, smooth sternaulus, which is about as long as the middle basitarsus. 



Tergite i strongly narrowed from base to apex, highly polished, its large basal part highly 

 shining and bare. Median field of tergite (2 + 3), having the form of an equilateral triangle but 

 its posterior corners indistinct. 



Length: 3 mm.

PARENION gen. n. 



Type-species : Microgaster kokodana Wilkinson. 



Scape long (Text-fig. 243). Side of pronotum without trace of a dorsal furrow. Disc of 

 scutellum polished, strongly convex. Propodeum somewhat depressed along the middle and 

 with medial keel ; each half highly polished and markedly convex. Stigma narrow, emitting 

 radius far distal to middle ; 1st abscissa of the radius as long as the 1st transverse cubitus, the 

 two veins together forming a strongly, almost semicircularly, curved vein ; areolet extremely 

 small (Text-fig. 250). Inner spur of the hind tibia very powerful, about three quarters as long as 

 the hind basitarsus ; hind coxa very large. Ovipositor very short, its sheaths about as long as 

 the 2nd segment of the hind tarsus. Hypopygium evenly sclerotised all over. 



The essential characters of the genus lie in the wing- venation, especially that of the 

 hind wing. The general fades, large hind coxae, short ovipositor and evenly sclero- 

 tised hypopygium indicate a fairly close relationship with Protomicroplitis s.L. 



Parenion kokodana (Wilkinson) comb. n. 



Microgaster kokodana Wilkinson, 1936 : 87. 



<J$. Reddish fulvous. Wings rather strongly embrowned. Legs reddish fulvous with the 

 hind tarsus darkening distal to middle. 



Top of head polished, impunctate. Mesoscutum strongly, rather coarsely punctate. Hind 

 coxa sharply punctate on a very shiny surface. Tergite 1 slightly widened from base to apex, 

 about two and a half times longer than wide, with weak medial furrow, its surface uneven by 

 reason of a few elongate pits and depressions. Tergite (2 + 3) without a delimited medial field 

 at base but with a lateral groove isolating both the anterior corner of the segment and the 

 extreme lateral margin (Text-fig. 249). 



Length: ca. 4 mm.

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



As a species, Parenion kokodana is remarkably distinct and without close allies.
