Head slightly shining, finely and superficially reticulate, except in 

 the middle of the vertex anteriorly, which, like the clypeus and frontal 

 area, is smooth and shining. A few fine longitudinal rugae between 

 the eyes and frontal carinae. Mandibles shining, very feebly striate. 

 Thorax dull, closely and finely reticulate, petiole and abdomen smooth 

 and shining. Head ovoid, excluding the mandibles at least one-third 

 longer than wide, much narrower behind than in front, the posterior 

 margin being formed by the articular border only. Eyes large, 

 convex, placed a little in front of the middle of the sides. Clypeus 

 not carinate, shallowly emarginate in the middle anteriorly. Frontal 

 area well-defined ; frontal carinae slightly convergent behind ; not 

 reaching as far as the level of the front of the eyes. Antennae thin 

 and very long, extending back as far as the middle of the abdomen, 

 the scape alone reaching as far as the middle of the mesonotum; 2nd- 

 8th joints of the flagellum twice as long as wide, or even longer. 

 Pronotum long, without tubercles ; pro-mesonotal suture obsolete. 

 Mesonotum long and narrow, clearly longer than Avide, and with a 

 transverse impression at about its anterior third. Meso-epinotal 

 suture deep. Dorsum of epinotum twice as long as wide, the teeth 

 erect, feebly divergent, acute, and about half as long as the interval 

 between their bases. First segment of petiole like that of the 1/, 

 but with the dorsal edge convex transversely and not emarginate. 

 Second segment of petiole pyriform, one-third longer than wide. 

 Legs long and slender. 



Belingwe, S. Rhodesia. The nest was placed in a hole in a tree- 

 trunk, about 3 ft. from the ground, and contained decayed leaves 

 and earth. 



This species has some affinity to the Prelli group. It is also allied 

 to P. Escherichia Forel, by the shape of the head in the $ , but differs 

 from it in that caste by the length of the antennae, by the sculpture 

 and the pyriform 2nd node ; in the 1/ it differs by the carinate clypeus, 

 the longer scapes and also the sculpture. In the ^ it bears a strong 

 resemblance to P. areniphila, Forel, especially in- the shape of the 

 head, but differs very considerably in the much longer antennae, the 

 different sculpture of the pronotum, and the narrower and longer 

 2nd node. The 1/ is quite different from that of areniphila, as the 

 head is differently formed and has no trace of a scrobe. 



I have much pleasure in naming this species in honour of Mr. 

 H. B. Maufe, Director of the Geological Survey, S. Rhodesia, whose 

 hospitality enabled me to do some collecting in the rather out-of-the- 

 way Belingwe district.
