portion, the apex slightly constricted. Apical dorsal segment 

 flattened, subcarinate in the middle, the latei'al margins raised 

 and nearly paiuUel, the apical incision subtriangulai', not quite as 

 deep as the apical width. Second and thixxl abscissae of the radius 

 nearly equal in length ; second recurrent nervure strongly curved 

 outwards below the middle, joining the cubitus just before one- 

 foui-th from the base of the third cubital cell. 



Hah. Johannesburg, Transvaal ; Kroonstad. 



The type is much damaged and without wings ; the details of 

 neuration are taken from a more recent specimen in which the 

 cubitus of the hind wing on the right side is almost interstitial 

 with the transverse median nervure, but is further removed 

 towards the base on the left side.

 Long. 13 mm, 



S . Clypeus short and broad, rather narrowly produced in the 

 middle and very feebly emarginate at the apex. Eyes widely 

 emarginate ; cheeks very much narrower than the eyes ; posterior 

 ocelli more than half as far again from the eyes as from each 

 other, Antennal tubercles well developed ; antennse longer than 

 the head, thorax, and median segment combined, of even thick- 

 ness throughout. Head punctured-rugose, much wider than the 

 thora.x ; the whole thorax finely and closely punctured, with 

 sparse white pubescence ; pronotum a little longer in the middle 

 than the scutellum, narrowed anteriorly, the anterior margin 

 straight, posterior margin strongly arched. Median segment 

 rounded posteriorly, not truncate, very closely but not coarsely 

 punctured. Abdomen slender, slightly shining, very finely and 

 sparsely punctured, petiolate ; the petiole occupying the basal 

 third of the first segment, the apical two-thirds elongate pyriform, 

 the whole segment half as long again as the second, which is 

 gradually broadened from the base, a little longer than the apical 

 width ; third segment broader than long. Apical dorsal segment 

 slightly convex, subcarinate longitudinally in the middle, shining, 

 with a foAV large punctures, the apical emargination a,lmost as 

 deep as its Vjreadth at the apex. Radial cell pointed : second 

 abscissa of the radius shorter than the third, but much longer 

 than the first ; second recurrent nervure received at one-third 

 from the base of the third cubital cell.
