sides and apex of scutellum, a short narrow line on the side of the 

 mesonotum in front of it, a large irregular mark on the centre of the 

 metanotum, the middle of the suturiform articulation, an irregular 

 spot, widest behind, on the centre of the third abdominal segment 

 and the whole of the others, red. Oral region, base of mandibles and 

 malar space, reddish yellow. Wings dark fuscous, tinged with 

 violaceous, the basal third of stigma ochraceous ; an oblique hyaline 

 cloud in the first cubital cellule, continued into the discoidal. ? . 



Length 12 mm. ; terebra 20 mm. 



Natal ; Estcourt. Transvaal ; Potchefstroom. 



Face coarsely rugosely-reticulated, covered with long black hair ; 

 the rest of the head and thorax smooth and shining. Antennal 

 scape shining, sparsely covered with long black hair, as long as the 

 second and third joints united ; the latter are equal in length. First 

 abdominal segment smooth, the apex closely, longitudinally striated ; 

 the area on second segment large, triangular, longer than the width 

 of the base, reaching to the middle of the segment, closely longitudi- 

 nally striated ; the space between it and the outer keel stoutly, 

 obliquely striated on the sides, at the apex longitudinally striated ; 

 the outer part with some oblique stout striae running fi-ora the longi- 

 tudinal keels ; the second and third segments with the transverse 

 furrows closely striated. Hypopygium cultriform, projecting beyond 

 the apical segments. Apical abscissa of radius shortly but distinctly 

 longer than the basal two united ; the second cubital cellule about 

 three times longer than wide. Calcaria testaceous ; tarsal spines 

 black. Legs moderately covered with black hair ; the hind coxae 

 about three times longer than wide. The size of the rufous markings 

 on the thorax varies. 



The Group of I. duibaneiisis. 

 Black, the mesonotum, scutellum, and pleurie marked with blood-red marks; 

 wings black, with ochraceous stigma ; abdomen strongly striated ; the keel on 

 second segment reaching to the apex, striated and triangularly dilated at the

Iphiaulax durbaneksis, sp. nov. 



Deep black, shining, a broad line on the sides of the mesonotum 

 at the tegulae, scutellum and post-scutellum, the mesopleurae, except 

 for an oblique mark on the upper basal edge, and the mesosternum 

 bright, sealing-wax red ; wings uniformly dark fuscous, except for a 

 small hyaline cloud at the base of the first cubital cellule ; basal two- 

 thirds of the stigma chrome-yellow. $ . 



Length 12 mm. ; terebra 7 mm.
