[6] 



pale fuscous, almost testaceous; the apical abscissa of the 

 radius straight, oblique, as long as the basal 2 united, the 

 2 nd thickened at the base and slightly eurved upwards; the 

 l st and 2 nd abscissse of the radius are slightly, broadly 

 turned downwards. Head and mesonotum minutely punctured; 

 the metanotum strongly punctured, the punctures clearly 

 separated; down the centre are 2 stout keels forming a 

 longish area, closed at the base by a narrower keel, which 

 is roundly dilated backwards in the middle; inside are stout. 

 clearly separated transverse keels. Propleurae smooth, the 

 mesopleurse weakly, but distinctly punctured on the dilated 

 upper half; the metapleurse more strongly punctured; on the 

 lower half are 3 arese formed by stout keels; the basal is 

 narrower than the others and is narrowed above through the 

 basal keel curving roundly above to the 2 nd , which is straight; 

 the 2 nd area is larger and is also narrowed above through the 

 2 nd keel curving roundly towards the l 8t above; the 3 rd 

 area is short, not reaching to the middle of the 2 nd below; 

 it is triangulär, its basal keel curved, the apical one straight. 

 Abdomen closely reticulated, the reticulations becoming finer 

 and closer towards its apex; the l st segment is clearly 

 separated from the 2 nd ; in its centre are 2 arese; the l st on the 

 basal slope; it is wider at the base, becoming gradually narro- 

 wed towards the apex, the keels becoming united to the basal 

 outer edge of the apical area; the keels bounding the latter 

 are rounded at the base and converge slightly towards 

 the apex. $ . 



Length 6 mm. 



Cape Colony (Krebs). 



Antennae 35-jointed, densely covered with short black 

 pubescence. Palpi and mandibles luteous. Face closely, 

 somewhat strongly punctured; the centre depressed, the 

 depressed part with broad outer edges. Ocellar region 

 raised; a keel runs from the outer ocelli to the antennae. 

 Apex of abdomen broadly rounded, the serration close and 

 uniform. Parapsidal furrows distinct, and there is a furrow 

 in the middle of the basal lobe. 



Apart from the difference in colouration (serrata has the 

 thorax not black, but coloured like the abdomen) this
