Mandibles finely striate, armed with five teeth, the apical tooth acute. 

 The scape extends back as far as the occipital margin ; 1st joint of 

 flagellum nearly as long as the 2nd-4th taken together ; 2nd-8th 

 joints wider than long. Eyes not large, situated a little in front of 

 the middle of the sides. Thoracic sutures obsolete. Thorax widest 

 anteriorly,' the shoulders sharply defined, subangular. The epinotum 

 is armed with a tooth on each side, which is directed upwards and 

 slightly outwards, and is not longer than it is broad at the base ; the 

 declivity is almost vertical. The dorsum of the thorax is widened and 

 subdentate at the lateral margins, above the posterior stigmatic 

 orifices. The 1st joint of the petiole has a short peduncle ; the node 

 is as wide as long, moderately convex above, and, seen from above, 

 more or less hexagonal in outline ; the anterior face of the node slopes 

 forwards ; the ventral lamella at the base has a small downwardly 

 directed spine. The 2nd joint of the petiole is subquadrangular, one 

 and a half times wider than long, nearly one and a half times as wide 

 as the 1st. Abdomen oval. All the femora swollen in the middle ; 

 middle and hind tibiae without calcaria. 



Khami R. and Matopo Hills, S. Rhodesia. 



I have met with this species only on the trunks of trees, previously 

 mentioned as being the habitat of Monomorium arnoldi. (S.A.M., 

 R.M., G.A. colls.)

" ^ . 3-2 mm. Reddish yellow, last joint of flagellum brownish, 

 mandibles pale yellow with dark brown teeth. The clavate hairs are 

 moderately sparse ; the fine pubescence of the abdomen very sparse. 

 Mandibles longitudinally striate, quadriclentate. Head rectangular, 

 longer than wide, with rounded corners, narrower in front than 

 behind ; longitudinally striate ; the middle of the vertex less coarsely 

 striate and somewhat coriaceous and feebly shining ; the outer thirds 

 of the head more reticulate- rugose, and round the eyes clearly punctu- 

 late. The disc of the clypeus is flattened (more so than in angulatus), 

 and has a median carina and two lateral carinae, which separate it 

 from the lateral portions of the clypeus ; the median carina is not 

 continued back on to the posterior portion of the clypeus, which lies at 

 a different level to the rest of the clypeus. . . . The scape does not 

 extend back as far as the posterior margin of the head ; the 2nd-8th 

 joints of the flagellum wider than long ; and the joints which form the 

 club, especially the last two, are only feebly constricted off from each
