140 Annals of the South African Miisenm. 



upper part of the propleurae is distinctly, regularly punctured, the 

 lower obscurely striated ; the upper basal part of the mesopleurse 

 closely punctured; the raised apical smooth, the lower closely 

 punctured-reticulated, as is also, but more strongly, the meta- 

 pleurae. Areolet 5-angled ; the recurrent nervure is received 

 shortly beyond the middle ; the transverse median shortly beyond 

 the transverse basal ; the stump on the disco-cubital nervure is 

 distinct. 



'^' Ckyptus natalensis, sp. nov. 



Head and thorax red ; the sutures of thorax, the sides of the 

 scutellum, base of mesonotum narrowly, the apical slope from 

 the keel, the lower basal part of mesothorax, the middle of meso- 

 sternum, the sternal furrow, the upper edge of metapleurae and 

 the lower half, black; the abdomen black, the apex of penultimate 

 and the whole of the last above, white. The anterior legs dark 

 rufous, the four posterior black, the middle tibiae tinged with 

 rufous. The apex of the sixth antennal joint and the sixth to 

 ninth joints white. Wings hyaline, the costa, stigma, and nervures 

 black, 5 . 



Length 10-11 mm.; terebra 3 mm. 



Natal. 



Centre of front transversely striated, with a smooth furrow down 

 the middle ; the sides punctured ; the vertex strongly punctured 

 between the ocelli, the sides much more obscui-ely punctured. 

 Clypeus shining, smooth. Apex of mandibles black ; the malar 

 space black behind them. Mesonotum closely punctured ; the 

 apex of middle lobe closely reticulated ; the furrows transversely 

 striated. Scutellum sparsely punctured ; its apical slope more 

 closely and with a striated band on the sides. Base of metanotum 

 closely reticulated ; the middle behind the keel much more widely 

 and irregularly reticulated ; the black apical slope is irregularly 

 longitudinally striated above and on the sides, the striiE being 

 twisted ; the centre is closely, rugosely reticulated. There is only 

 one transverse keel — the apical ; it is dilated into blunt teeth at the 

 sides. Pleurae closely punctured ; there is a striated border on 

 the apex of the latter ; the apex of the metapleurae is more broadly 

 and somewhat strongly reticulated-striated. Antennal scape red. 

 Areolet 5-angled, receiving the recurrent nervure shortly beyond the 

 middle; the transverse median nervure received shortly behind 

 the transverse basal.
