 darker." 



I have specimens from Durban (leg. C. P. v. d. Merve), which 

 agree very well, according to the description cited above, with the 

 type species, but the colour is not lighter than in var. nalalensis, 

 but darker, being of a very dark brown, the head almost black.

Characters. 



^. Antennae 12-jointed, long, inserted behind the frontal area but 

 near the anterior ends of the frontal carinae ; 1st joint of the flagel- 

 lum very long. Maxillary palpi 5-jointed. Mandibles large, the 

 masticatory margin long, longer than the basal, armed with nume- 

 rous small teeth, the apical one large, acute and curved. Clypeus 

 large; frontal area subtriangular. Frontal carinae short and fairly 

 far apart. Eyes large, very convex and outstanding, almost hemi- 

 spherical. Pronotum narrowed into a long neck in front. Pro- 

 mesonotal suture well defined, the meta-epinotal a little less so. 

 Thorax strongly constricted and depressed along the meso- and 

 metanotum , seen in profile, saddle-shaped. Epinotum unarmed , 

 much higher than the metanotum. Petiole elongate, incrassate pos- 

 teriorly, the posterior end produced into a small lamelliform flap on 

 each side and embracing the abdominal articulation. Abdomen oval 

 or subcircular. Legs long and slender. 



Q. Antennae as in the ^. Pronotum not visible from above. 

 Mesonotum wide and gibbous in front. Scutellum much wider than 

 long. Petiole subquadrate, short, seen from the side more or less 

 obtusely conical. Wings with 1 cubital, and 1 closed radial cell 

 which is rather long. 



"cf. Head relatively small; the mandibles porrect, very hairy 

 and with an indistinct masticatory margin; ocelli prominent: eyes 

 very large and prominent, giving great width to the head; antennae 

 13-jointed, filiform, the scape long, thickening slightly towards the 

 apex, the basal joint of the flagellum remarkably clavate. Thorax 

 very massive, the mesonotum broad and gibbous anteriorly, the pro- 

 notum sunk well below its level in front; scutellum large, laterally 

 compressed, the rest of the thorax and epinotum sloping gradually
