290 Annals of the South African Museum. 



Head robust, as long as wide, the sides moderately convex, the 

 posterior angles rounded, the posterior margin straight, the upper 

 surface distinctly convex. Anterior margin of clypeus widely but not 

 deeply emarginate in the middle. Mandibles with 6 blunt teeth. 

 Frontal carinae short, divergent, not extending beyond the first third 

 of the head. Scapes short, extending back very little beyond the 

 middle third of the head. Thoracic sutures obsolete. Shoulders of 

 the pronotum angular. Thorax much wider in front than across 

 the epinotum, hardly constricted between the meso- and epinotum, 

 distinctly convex lengthwise, short, hardly one-third longer than it is 

 deep. .Epinotal spines long and acute, longer than the interval 

 between their bases, slightly divergent along their basal half, parallel 

 along the apical half, directed obliquely upwards. Episternal teeth 

 small and obtuse, forming almost triangular lobes. The peduncle 

 of the 1st segment of the petiole is a little more than half the length 

 of the node, and furnished below with a small tooth near the base ; 

 the node is truncate in front, seen from above trapezoidal, with dis- 

 tinct but rounded anterior and posterior lateral angles, the posterior 

 margin nearly twice as wide as the anterior, the sides barely convex. 

 Second node transversely oblong, two and a half times wider than 

 long, nearly one-third wider than the 1st,' the posterior margin mode- 

 rately convex. Abdomen truncate at the base, with pronounced lateral 

 angles. 



$. 7 mm. (Hitherto undescribed ?) Sides of head less convex 

 than in the ^ . Sculpture of the head stronger, mesonotum and 

 scutellum longitudinally rugose, sides of pronotum reticulate-rugose 

 and punctured in between the rugae, the dorsum and sides of the 

 epinotum very closely granulate-punctate, with some more or less 

 longitudinal rugae superimposed, the declivity coarsely and trans- 

 versely striate. The epinotal spines are relatively shorter and thicker 

 than in the ^ , about as long as their basal width, shorter than the 

 interval between them, horizontal. The dorsum of the epinotum is 

 very short, almost obsolete in the middle. The 1st node is shorter, 

 quite twice as wide behind as it is long (only one-third wider than 

 long in the ^). The raised anterior angles of the node bear a pair 

 of minute and nearly vertical teeth, between which the surface of the 

 node is concave. The 2nd node is much more convex at the sides, 

 and is nearly two and a half times wider than long. Basal two-thirds 

 of 1st abdominal segment finely and very closely, longitudinally striate, 

 with punctures between the striae. 



Wings strongly tinged with yellow, the nervm-es yellow, the stigma 

 yellowish-brown. Otherwise like the $ .
