longitudinally striated, smooth at the apex below. Scutellum longer 

 than the width at the apex, broadly, but not deeply, furrowed down 

 the middle ; the apex ending in two stout teeth, which are longer on 

 the outer than on the inner side ; the incision separating them forms 

 a triangle ; they project largely over the median segment. The latter 

 is widely areolated ; there is a long central area extending from the 

 base to the apex and roundly widened in the middle ; in the centre 

 are three irregular transverse keels. At the base of the segment is, on 

 either side, a large irregular area, wider than long. It is narrowed on 

 the outer side, where there are some irregular broken striae ; on the 

 sides of the apex are two areas stoutly striated. Metapleurae reticu- 

 lated; the apical half above with an area, which is roundly incised in 

 the middle at the apex and narrowed at the base. Abdomen shorter 

 than the thorax ; the hypopygium short, triangular. The apex of the 

 hind femora below is keeled ; behind this are two not very distinct, 

 rounded curved projections. The third joint of the antennae is about 

 one-fourth longer than the fourth. Malar space as long as the eyes. 

 The keel bordering the apex of the clypeus projects upwards on to 

 the middle of the malar space. Tegulge conchiform, densely covered 

 with white pubescence. 



StOMATOCEEAS TRIFASCIATUS, sp. nOV. 



Black ; the scape and basal 5 joints of flagellum red ; the apex of 

 the 4 front femora, the fore tibiae in front, the hind femora in the 

 middle broadly on the inner side and the base of the femora, dark 

 rufous ; wings hyaline ; there is a brownish cloud at the stigma, 

 longer than wide and narrowed at the apex ; opposite it is a smaller 

 cloud, and beyond, half-way between it and the middle, a longer 

 curved one, narrowed in front. $ . 



Length to end of hypopygium 8 mm. 



Cape Town. 



Head rugosely punctured, the frontal depression closely, minutely 

 punctured ; the eyes, on the inner side, bordered by a keel. Apex of 

 clypeus broadly roundly, but not deeply incised ; malar space as long 

 as the eyes ; there is a smooth keel down the middle. Mandibles 

 rufous, black at the apex, pro- and meso-thorax closely punctured ; 

 the pro- more strongly than the mesonotum, and the apex of the 

 mesopleurae still more strongly; the base of the latter stoutly 

 striated, except below ; the striae are clearly separated. Meta- 

 pleurae coarsely, rugosely punctured, roundly projecting below. 

 Smooth and thickly covered with white pubescence. Metanotum
