shape of the node is distinctive, the base being emarginate with small 

 lateral angles, behind which on each side lies a flattened projection. 

 The node of the petiole is only half as wide as the 1st abdominal 

 segment. The latter is nearly as long as wide, sub-campaniform, 

 and separated from the 2nd segment by a well-marked constriction. 

 The 2nd segment is two-thirds wider than long, the sides slightly 

 convex. Abdomen as long as thorax and petiole together. Pygidium 

 narrowly truncate. Legs slender. Wings sub-hyaline, somewhat 

 darker towards the apex, stigma brown, nervures pale brown ; 2 

 sub-marginal cells, radial cell lanceolate. 



This species is fairly generally distributed. Specimens from 

 Willowmore and Grahamstown are rather small, but otherwise 

 agree with the type. They are intermediate in size and puncturation 

 between the type form and the smallest form which I have received 

 from Durban. The entrances to the nest are generally indicated by 

 large heaps of earth. The chambers are placed deep below the 

 surface, seldom less than 2 feet, and the number of individuals 

 seldom exceeds 50. It is a sluggish and timid ant, the workers 

 foraging singly. The food includes termites, but consists chiefly of 

 millipedes and beetles.

This differs from the type form in having the dorsal surface of the 

 head, thorax and 1st segment of abdomen finely and regularly 

 striate, longitudinally so on the head and thorax, transversely on 

 the petiole, concentrically on the 1st abdominal segment and 

 slightly so on the 2nd. The petiole is a little shorter than in 

 the type form. Natal.
