- Mesoscutum quite differently sculptured ; the surface is closely punctate, with the 

 punctures becoming a little less close posteriorly (but not to the same extent as in 

 orphne and trifasciatus) ; further, the surface of the mesoscutum has a fine micro- 

 sculpture and a satin-like sheen ; edge of vannal lobe straight and without a hair- 

 fringe ; propodeum with a median, rugulose area that is slightly hollowed out but 

 much less so than in cyane ; surface on each side of propodeum faintly dull, owing 

 to fine microsculpture ; propodeum shorter than in cyane and like that of trifasciatus 

 and orphne ; ovipositor sheath as long as the hind tibia ; ovipositor itself decidedly 

 thick ; mesopleural furrow more shallow than in cyane ; dull and filled with 

 extremely fine aciculation ....... eurynome sp. n. 



Fiji Is. : Viti Levu, 29.x. 1954, x $. the TYPE, (B. A. O' Conner), labelled ? ex 

 Cryptophlebia pallifimbriana Bradley (Olethreutidae) in fruits of Inocarpus edulis. 

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



The faint proximal cloud of the fore wing hardly extends into the median cell ; 

 the median cell has sparse setae situated over its entire surface but they are still spar- 

 ser along the medius side of the cell ; the hind tarsus is only slightly longer than its 

 tibia ; in this respect, eurynome differs from both trifasciatus and orphne. The 

 antenna is short with the three preapical segments slightly transverse. 



The ULTOR-Groxjp 



Essentially characterized by the possession of three features, namely, (1) a sharp, 

 very well defined punctation on the mesoscutum without a trace of longitudinal 

 striation at the posterior end of the imaginary course of the notaulices, (2) a postero- 

 lateral propodeal field that is always distinctly a little transverse and (3) a vannal 

 lobe with an evenly convex edge that is fringed throughout with short hairs (Text- 

 fig. 5). In addition, the following features should be noted: — tergite 1 is usually 

 parallel-sided, sometimes slightly widened apically but never wedge-shaped as in 

 many species of the superficially similar ater-groxvp. 



The group is rich in species in the tropics of the Old World and I know only of a 

 few species from Europe including ultor Reinhard. 3 It is more homogeneous than 

 the equally abundant ater-group. These two groups together make up the bulk of 

 Wilkinson's group S, into which he put all species having a well marked propodeal 

 areola. 



The NIGRICEPS-Groxjp 



The few species that I consider to form this group are all American. The species 

 are chiefly characterized by the curiously unpigmented cheeks, a very smooth- 

 looking, virtually impunctate mesoscutum that is clothed rather densely with silky 

 hairs, the form of the first tergite and the short, evenly sclerotised hypopygium. 

 The group may later be shown to have no more value than that of a small segregate 

 within the large ater-group to which it is, in any case, closely related. 



The type of Apanteles nigriceps (Ashmead) 4 is in the British Museum (Nat. Hist.).
