 basal flagellar segments only slightly oblong or (in smaller specimens) sub- 

 quadrate, flagellum plus pedicellus combined 1 -03-1 -23 times as long as breadth 

 of head; puncturation of hind femur even in darker-coloured specimens rather fine

- Head in facial view longer (Text-fig. 155), only 1 -08-1 '15 times as broad as high, 



with longer genae and basal (and in specimens larger than 6 mm also middle) 

 flagellar segments distinctly oblong, flagellum plus pedicellus 1 -22-1 -44 times as

The ELEGANS-Grovp 



The species belonging here always have a very distinct discal carina on the 

 pronotura, often very high and then more or less strongly angulate. The hind 

 tibia is apically produced into a distinct spine but this has concave adtarsal margin, 

 although usually not so strongly as in the Oriental species of the group. On the 

 other hand the Ethiopian species usually have the middle teeth on hind femur 

 relatively slender, thus suggesting an intergrade towards the species-groups with 

 the median teeth the longest. 



Apart from the Mediterranean L. brevicauda Fabricius treated elsewhere (p. 00), 

 and of the Asiatic species, the following African species belong here: Leucospis 

 insularis Kirby, L. africana Cameron, L. fallax sp. n., L. elegans Klug, L. ornata 

 West wood, L. carinifera Kriechbaumer, L. varicollis Cameron, L. osniiae sp. n. 

 and L. pubescens sp. n. 



Leucospis insularis Kirby 

 (Text-figs 121, 122) 



Leucospis insularis Kirby, 1900 : 13-14, 9- Holotype $, Sokotra: Jena-agahan (BMNH) 

 [examined] . 



L. insularis is a rather distinct species with weak pronotal carinae, swollen 

 rounded dorsellum, fairly slender hind femur and rather long thin pubescence of 

 the body. Only the holotype is known so far. 



Biology. Host unknown. 



Distribution. Sokotra Island. 



Leucospis africana Cameron 

 (Text-figs 123-126) 



Leucospis africana Cameron, 1907 : 204—205, $. LECTOTYPE $ (here designated), South 

 Africa : Cape Province (BMNH) [examined] . 



In colour this species varies considerably but what is more unusual is the variation 

 of the teeth on the hind femur. In some specimens (e.g. most females from southern
