have a long, oblique and decumbent pubescence, but no erect 

 pilosity." 



As far as one can judge from the above description, this species 

 should be placed in the Punctulata group, and appears to stand 

 nearest to rotundata, in which the head is also distinctly depressed 

 behind and shows faint traces of scrobes.

 " 1/ 32 mm. Resembling P. minima, Mayr, but the frontal carinae 

 are not prolonged backwards, and do not form scrobes. Mandibles 

 smooth, feebly punctured. Clypeus shallowly emarginate in the 

 middle, also feebly carinate in the middle, and having a longitudinal 

 carinula on each side extending from the articulation of the antennae 

 to the anterior margin. Head fairly depressed, obtusely rectangular, 

 the sides convex, slightly longer than wide, feebly concave behind, as 

 wide in front as behind, with a deep occipital sulcus joining the frontal 

 sulcus. Eyes fairly small, placed at the anterior third. The scape 

 does not reach the posterior third of the head. The pro-mesonotum 

 forms a single convexity, without a transverse impi-ession or torus ; it 

 is, however, truncate behind and margined above on each side with a 

 little ridge. Epinotal spines acute, shorter than half the space between 

 them. Petiole as in P. punctulata, Mayr, but the 2nd node a little 

 nari'ower. Pronotum without prominent posterior lateral angles. 

 Anterior half of the head longitudinally rugose ; a few rugae and 

 reticulations on the sides of the epinotum. The rest of the body 

 smooth. Erect pilosity yellowish, sparse on the body, absent from the 

 tibiae and scapes, which have only sparse, oblique, or nearly decumbent 

 hairs. Brownish-yellow ; legs and antennae dirty yellow. 



" $ ('?). 2*5 mm. Head oval-rectangular. Mandibles dentate, striate 

 near the base. Clypeus without carinae, feebly emarginate. The 

 mesonotum with two small ridges behind, as in the %. Epinotum 

 subdentate. Head fairly smooth in front, excepting a few rugae in 

 the antennal hollows ; epinotum reticulate. Otherwise in sculpture, 

 pilosity and colour like the 1/ . 



"Mountains of Natal (Wroughton). A species distinctly charac- 

 terised in the 1/ by the shape of the head, clypeus and mesonotum."
