zoidal, very feebly convex above. The pronotum is twice as wide as 

 long, its lateral margins acute, owing to the sides and dorsum meeting 

 in a rectangle, the anterior angles or shoulders narrowly rounded. 

 Pro-mesonotal suture distinct. Mesonotum subovate transversely, 

 twice as wide in front as behind, nearly one-third wider than long. 

 Meso-epinotal suture deep. Dorsum of epinotum subquadrate, a 

 trifle longer than wide behind and a little wider there than at the base, 

 its lateral margins slightly convex, concave transversely over its 

 apical half, the apical margin deeply and arcuately emarginate in 

 the middle ; declivity concave from above to below, its brow over- 

 hanging the lower part, longer than the dorsum. Scale of petiole 

 subcircular, wider than high, both faces equally convex, the dorsal 

 edge fairly sharp, and feebly emarginate in the middle in the largest 

 specimens. Abdomen almost circular in outline, very little longer 

 than wide. Tibiae cylindrical, not setose below. 



$ minor, 4-4-5 mm. Like the 2i, but with the head more narrowed 

 in front, the posterior margin moderately convex. The shoulders 

 of the pronotum more acute, rectangular. The dorsum of the 

 epinotum very little longer. 



"$, 11-5 mm. The head is very similar to that of the 21. From 

 each of the larger punctures arises a decumbent, whitish yellow, 

 short and very shining pubescent hair ; a similar pubescence also 

 occurs on the back of the head, on the thorax and especially on the 

 upper side of the abdomen. The anterior wings are 10-8 mm. long 

 and of a yellowish brown colour." 



The $$ from East Africa, described by Santschi, are smaller, 

 9-5-10 mm. long. 



Plumtree, S. Rhodesia ; crawling over the trunks of trees in the 

 same slow and apparently aimless way as the species of Cataulacus, 

 for which it might easily be mistaken at a first glance. Apparently 

 a scarce insect, recorded from our region only from the locality cited 

 above and from Delagoa Bay, (Dr. H. Brauns).

 2J., 8-8-5 mm. Black, the legs castaneous red, the tarsi, flagellum, 

 mandibles and apical half of the scapes dark reddish brown, the basal 

 half of the scapes dark red. 



Very similar to Braunsi but larger, differing from it only as follows : 

 The sculpture is everywhere a good deal finer, especially on the
