Possibly the sparse pilosity on the scapes and tibiae constitutes a 

 variety, and is not merely a ? character."

Bace indefinita, Forel. 

 (as var. of gagates) Bev. Zool. Afric, vol. 2, p. 349, 1913. 



"$, 11 mm. This race differs from P. nigriseta Santschi by having 

 the eyes about intermediate in structure between that species and 

 P. gagates. They are not so strongly convex as in nigriseta, nor 

 entirely flat as in gagates, but very feebly convex. Otherwise exactly 

 like gagates.'' 



Selukwe, S. Bhodesia, (A. E. V. Zealiey). 



(S.A.M., B.M., G.A. colls.). 



Indefinita, var. acheron, n. v. 



$, 10-10*5 mm. Eyes distinctly convex, (about one-third of a 

 sphere), the convexity twice as strong as in indefinita. Sculpture 

 much more superficial than in either gagates or indefinita, the thorax, 

 especially the pro-mesonotum, being almost as shining as the abdomen. 

 The pronotal spines are more distinctly incurved at their apex than 

 in indefinita. The lateral margins of the dorsum of the epinotum 

 moderately convex outwardly. Abdomen distinctly more shining 

 than in gagates or indefinita. Otherwise like the latter. 



Hillside, Bulawayo. The nest under a large rock, the entrance 

 surmounted by a wall of woven material, which also lined the first 

 three or four inches of the gallery.

This species has not, to my knowledge, been recorded within our 

 limits, but as it or some of its varieties occur in the adjacent regions, 

 it is possible that they may be recorded later on from parts of Natal 

 or the eastern part of S. Bhodesia, and a description is therefore 

 desirable.
