The COENONYMPHAE-Grovp 

 Monobasic. 



Protomicroplitis coenonymphae (Watanabe) comb. n. 



Microgaster coenonymphae Watanabe, 1937 : 101. 



$. Head and thorax blackish ; gaster in greater part yellow-testaceous with infuscation 

 across the tergites and within the hollowed out part of tergite 1 . Hind coxa almost entirely, and 

 the hind femur entirely, yellow-testaceous. 



Face strongly shining, almost smooth. Frons and vertex polished. Ocelli in a rather low 

 triangle, the posterior, transverse tangent to the anterior ocellus just cutting the posterior pair. 



Mesoscutum polished, impunctate. Disc of scutellum strongly convex, polished ; posterior, 

 polished band of the scutellum widely interrupted at middle by a patch of rugosity. Propodeum 

 somewhat flattened, with much unevenly distributed rugosity and a strong, medial keel. First 

 abscissa of the radius somewhat obliquely placed on the stigma. 



Tergite 1 coarsely rugose, with short medial furrow that does not cut through the medial 

 hump (Text-fig. 327). Tergite 2 with poorly defined, raised median field ; otherwise shiny 

 and with vaguely defined pits and rugosities ; lateral field of tergite 2 transverse. Ovipositor 

 sheath at tip without setiform appendages. 



Japan : Tokyo, (type locality). 



Type in Entomological Institute, (Hokkaido University). Two paratypes in 

 British Museum (Nat. Hist.). 



Host : Coenonympha oedippus F. (Satyridae) . 



This is an aberrant species. On the shape of the 2nd tergite and the short 1st 

 abscissa of the discoideus it perhaps comes closest to the connexus-gvou-p. The 

 completely smooth mesoscutum is a rare feature among the species-groups that I 

 include in Protomicroplitis. 



Behind the posterior polished band of the scutellum is a narrow, rugose groove — 

 a part of the scutellum — that, in its extension inwards, is confluent with the patch of 

 rugosity that interrupts the posterior, polished band. This sculptural feature 

 occurs in species of the xanthaspis-gvou-p but I have not fully explored its taxonomic 

 value. 



The LEPELLEY 7-Group 

 Monobasic. 



Protomicroplitis lepelleyi (Wilkinson) comb. n. 

 Microgaster lepelleyi Wilkinson, 1934 : n8. 



$. Body in greater part blackish ; anterior corners of tergite (2 -f- 3) pale. Legs obscure 

 brownish red with the hind coxa entirely dark. Wings hyaline. 



Face dull, rugose-punctate. Frons and vertex dull, densely rugose-punctate. The highly 

 polished occipital region is constricted on each side and sharply separated from the adjacent, 

 rugose surface. Ocelli in rather a high triangle, the posterior transverse tangent to the anterior 

 ocellus hardly touching the posterior pair. Antenna fully as long as the body, with the preapical 

 segment twice as long as wide. 



Mesoscutum dull, coarsely rugose-punctate ; the sculpture denser and finer anteriorly. Disc 

 of scutellum not separated from the lateral, rugose areas ; the disc itself coarsely punctate, dull 

 and sharply separated from the wide, polished, posterior band of the scutellum. Propodeum
