Descriptions of Species of Parasitic Hymenoptera. 209 



Centre of face and clypeus smooth, bordered by distinctly 

 separated punctures ; the sides opaque, closely punctured. Vertex 

 closely rugosely reticulated-punctured. Pro- and mesonotum 

 closely rugosely punctured ; the apex of clypeus bone-coloured ; 

 bilobate, the lobes rounded, the space between them straight, 

 transverse ; it is covered all round with long, white hair. Meta- 

 notum reticulated ; the reticulations wide, square at the base ; the 

 central basal area is about two and a half times longer than 

 wide ; it is narrowed towards the base ; the sides in the middle 

 are broadly, roundly dilated. Propleurae finely, closely striated 

 above ; the middle with a stout keel. Mesopleurse smooth, except 

 for the usual foveas at the base. Metapleur^ except on the 

 basal slope closely rugosely striated. Basal segments of the 

 abdomen smooth ; the others punctured and covered with white 

 hair in the middle. Femoral teeth short, stout, the basal close 

 to each other and regular ; the apical six larger and more 

 widely separated. Hind coxae closely and somewhat strongly 

 punctured. 



Chalcis melanogastra, sp. nov. 



Black, the apex of the fore femora and their tibige and tarsi 

 pale yellow ; the middle of the tibiae broadly dark rufous ; the hind 

 femora red, their apex yellow, their teeth black ; the tibise black, 

 a yellow band near the base and a longer one on the apex ; the 

 tarsi yellowish. Antennal scape obscure yellowish in the middle. 

 Wings hyaline, the nervures black. ? . 



Length 4 mm. 



Cape Colony. 



Apex of scutellum bilobate, the lobes short, broad, rounded. 

 Face strongly punctured, without a smooth central plate. Clypeus 

 smooth, with two longish foveae in the centre. Front and vertex 

 strongly rugosely punctured. The punctuation on the pronotum 

 is closer and more rugose than it is on the mesonotum and 

 scutellum, on which they are somewhat widely separated. Meta- 

 notum reticulated; the central area is about three times longer than 

 wide, and is slightly narrowed towards the apex ; the sides below 

 are dilated but not greatly; the dilated part becomes wider 

 gradually from the base and apex to the middle. Propleurae in 

 the middle stoutly irregularly striated, the apex above finely, 

 closely striated. Mesopleurae smooth and shining, the base and 

 lower part at the base foveate. Metapleurae closely rugosely
