distinctly wider than long. Eyes placed in about the middle of the 

 sides of the head. The fairly robust thorax is narrower than the 

 head, with obtuse and not prominent shoulders, coarsely reticulate 

 above, finely rugulose or punctate between the meshes, and seen in 

 profile, straight from the front to the pro-mesonotal suture, and 

 also straight from the latter to the epinotal teeth ; these two planes 

 meet in an obtuse and rounded angle. The meso-epinotal suture is 

 not very distinct, and the dorsum of the epinotum is only slightly 

 depressed. The latter is longer than wide, feebly concave transversely 

 behind ; the epinotal teeth are wide, almost blunt, fairly erect and 



moderately divergent ; episternal teeth rectangular, the 



sides of the thorax are in greater part finely and closely reticulate- 

 punctate. Petiole moderately coarsely reticulate-rugulose and finely 

 punctured ; the peduncle of the 1st segment moderately long, the 

 node a little wider than long, the 2nd segment hardly as long as, and 

 somewhat wider than the 1st node. Abdomen smooth and shining, 

 with scattered piligerous punctures; the base of the 1st segment 

 more or less distinctly and longitudinally striate. 



" ? . 45 mm. Very much like the ^ . The mesonotum and 

 scutellum rugoso- striate lengthwise, the dorsum of the epinotum 

 transversely rugose, the sides of the thorax longitudinally rugose 

 and also closely and finely reticulate- punctate. The wings slightly 

 infuscate, with pale yellow nervures. Otherwise like the ^ . 



" <$ . 4T-42 mm. Shining, brown, the mandibles, antennae and 

 legs, particularly the last four tarsal joints, brownish-yellow. The 

 long pilosity is scanty, more abundant on the ventral surface of the 

 abdomen ; the antennae and legs have only short, fine and oblique 

 hairs. Head fairly coarsely and longitudinally rugoso-striate and 

 finely reticulate, between the eyes and ocelli finely reticulate-punctate, 

 the ocellar area transversely rugose, the back of the head unevenly 

 rugose and finely reticulate. In the 7 specimens before me, the 

 antennae are 13-jointed, the scape extends back as far as the anterior 

 ocellus, the 1st joint of the fiagellum is a little longer than wide, 

 and wider than the 2nd joint, which is two and a half times, or a 

 little more, longer than wide. The head is gradually narrowed from 

 behind the eyes to the posterior angles, so that the latter project 

 outwards and are almost dentiform, as in the $ of T. guineense. 

 Thorax fairly finely and longitudinally rugose, the dorsum and 

 declivity of the epinotum finely and closely reticulate. Wings as in 

 the $ . The segments of the petiole are slender, much more so than 

 in guiueense, the 2nd segment hardly wider than long. The abdomen 

 in greater part smooth. Port Elizabeth."
