from above to below. Seen from above, the node is transversely oval. 

 Second node also transversely oval, as wide as the 1st, two-thirds 

 wider than long, the ventral surface armed with a small tooth on each 

 side in front. Abdomen truncate in front, the sides very convex, a 

 little longer than wide. 



Bulawayo, under stones, very rare. Occasionally found singly in 

 nests of Ponerine ants, where its presence is probably accidental. I 

 have never found more than half a dozen together in one place. It is 

 a very slow moving ant, and on account of its colour not easily seen 

 even at close quarters. The 2nd-8th joints of the flagellum are so 

 exceedingly short that they can be resolved only under a magnification 

 of at least 80 diameters, and it is therefore not surprising that this 

 species was originally placed by Dr. Forel under Dicroaspis.

" $ . 2 mm. Brownish-red. Head and dorsum of thorax darker. 

 Abdomen blackish-brown. Dull. Head and pro-mesonotum coarsely 

 and longitudinally rugose. The rugae are slightly divergent towards 

 the back of the head, and convergent behind on the thorax. The 

 spaces between the rugae are more finely rugose and covered with 

 large punctures, shining at the bottom, each one giving rise to an 

 erect clavate hair. The sides of the thorax, the epinotum and both 

 nodes finely reticulate and punctate. On the thorax and abdomen the 

 clavate hairs are fairly long and outstanding, also erect but shorter on
