Descriptions of Ncio Species of Parasitic Hymeiioptera. 171 



post-petiole becoming gradually narrowed towards the apex ; the 

 second and third segments weakly punctured ; the gastrocoeli 

 transverse, widely distant from the base of the segment ; there are 

 seven segments ; the apical bluntly pointed ; the ventral keel 

 extends to the fifth segment. x\ntenna3 stout, serrate. Clypeus 

 not separated from the face, its apex bluntly rounded ; the labrum 

 shortly projecting. Malar space and temples large ; the latter 

 obliquely narrowed. 



The $ I do not know ; but the ^ agrees best with the Joppini, 

 especially in the form of the scutellum, median segment and 

 antennae. The absence of areee on the metanotum seems to be 

 not uncommon with the African genera, or at any rate their being 

 greatly reduced in number. The same thing occurs with some 

 Oriental genera of Joppini. 



Phaisura nigriceps, sp. nov. 



Eufous, the head and the apical three segments of the abdomen 

 black ; the antennae of a paler rufous colour, with a whitish band 

 beyond the middle, the apex black ; wings fuscous violaceous, the 

 stigma and nervures black. ^ . 



Length 10-12 mm. 



Cape Town. 



Head as wide as the thorax ; the face strongly punctured ; the 

 clypeus impunctate, bare ; labrum rufo-testaceous, fringed with long 

 fulvous hair. Mandibles and palpi rufo-testaceous, the apex black. 

 Mesonotum closely, strongly punctured; the scutellum more strongly 

 punctured, the lower part of the apical slope smooth. Median 

 segment coarsely, closely punctured, the apical slope more or less 

 transversely striated. Pro- and mesopleurse closely, strongly punc- 

 tured, the former with a smooth triangular space below the middle. 

 First abdominal segment very smooth and shining, the following 

 three closely punctured. Apices of tarsal joints spinose ; the claws 

 very large. 



CEYTEA, gen. nov. 



Median segment short, deeply depressed at the base, regularly 

 areolated ; the areola small, horseshoe-shaped, wider than long, 

 widely separated from the base of the segment ; the spiracles linear. 

 Scutellum roundly convex, not much raised above the level of the 

 middle of mesonotum, the sides stoutly margined, the apex less 

 strongly keeled ; it has a longish steep slope on the apex. Head
