P. Akermani, n. sp. 



A rather small species of the sculpturata group, but also resembling 

 the capensis group in the relatively small size of the 1/ 1/ . 



1/ . 4"6-4 - 9 mm. Dark castaneous brown, the posterior fourth of the 

 head, the thorax and petiole with a redder tinge, abdomen piceous, 

 scapes, tibiae and tarsi raw-umber brown, femora brown but paler at 

 the bases and apices. Pilosity yellowish, oblique, fairly long and 

 moderately abundant ; pubescence inconspicuous except on the tarsi. 

 Head and thorax dull, abdomen and legs shining. 



Head closely and evenly reticulate-punctate, fairly strongly and longi- 

 tudinally rugose at the sides between the eyes and vertex, the latter 

 only longitudinally striate as far as the posterior third of the head 

 and with the fundamental reticulation absent between the striae, the 

 occipital lobes and lower surface of the head smooth, shining and 

 sparsely punctured. Mandibles shining, striate at the base, sparsely 

 punctured with deep and large punctures. Clypeus strongly carinate, 

 its anterior margin arcuately emarginate in the middle. Pronotum 

 finely and transversely rugulose, mesonotum rugulose-reticulate in 

 front, reticulate-punctate at the sides and behind. Epinotum and 

 petiole reticulate-punctate, the petiole very finely so. Abdomen very 

 finely striate longitudinally at the base medially. 



Head, excluding the mandibles, nearly one-third longer than wide, 

 barely wider behind than in front, the sides straight, the occipital 

 emargination angular, wide and deep, the occipital lobes rounded 

 behind. Occipital sulcus deep. Sides of the head behind the eyes 

 with an oblicpue and shallow depression. The scapes extend back as 

 far as the middle of the head.
