<$ . 4 mm. Black, tibiae, tarsi, scapes, and 1st joint of the 

 flagellum bright ochreous, the rest of the flagellum piceous. Dull, 

 reticulate-punctate. The head also finely reticulate-rugose, mostly 

 longitudinally. Epinotum and nodes coarsely rugose. Abdomen 

 moderately shining, finely and feebly reticulate. Head, seen from 

 above and excluding the convexity of the eyes, triangular, with the 

 apex of the triangle widely truncate. The portion of the head in 

 front of the eyes is much shorter in this species than in durbanensis. 

 The sides of the head without denticulations, the teeth on the posterior 

 margin very small. The head is a little longer than wide, wider 

 behind than the anterior margin of the thorax, but narrower than the 

 middle of the same. Mayrian furrows much deeper than in 

 durbanensis, and more coarsely clathrate. Dorsum of epinotum not 

 much narrowed apically ; the spines triangular, not longer than 

 wide at the base, the brow of the declivity shallowly arcuate. The 

 ]st node is widest in front, a trifle longer than wide, the middle 

 of the sides slightly angular. Second node without the subacute 

 anterior lateral angles which are seen in durbanensis. Wings hyaline, 

 faintly tinged with yellow. Pilosity longer and less obtuse than in 

 the ^ or $ . 



This race differs from the type, which has not yet been recorded 

 from our region, in the wider pro-mesonotum and the stronger 

 denticulations of the lateral margins. The meshes on the head are 

 also smaller and deeper.

ty . 3'6-3*9 mm. Colour as in the preceding species. Pilosity 

 longer than in micans- durbanensis. Head and abdomen with a faint 

 gloss, thorax fairly shining. Head longitudinally and not closely 

 striato-rugose, barely reticulate. The sculpture of the thoi-ax like that 

 of the head but stronger. The rugae on the pro-mesonotum number 

 about 10-12, and are rather wide apart, the spaces between them 

 feebly rugulose. Nodes fairly strongly rugose and sulcate. Abdomen 

 densely reticulate, with a few longitudinal rugae superimposed. Head 

 very gradually narrowed from the posterior angles to the apex. The 

 teeth on the posterior angles and on the sides behind the eyes acute
