margin more convex than in Constanciae. The thorax is narrower 

 posteriorly than in that species, the width across the brow of the 

 declivity being a little less than half the width across the anterior 

 angles of the pronotum (much more than half in Constanciae). 

 Epinotal teeth small and triangular, not longer than their basal width, 

 slightly divergent. The 1st node of the petiole, seen from above, is 

 transversely oval, one and a half times wider than long, the anterior 

 margin not more convex than the posterior, not semicircular as in 

 Constanciae. The 2nd node similar to that of Constanciae, transversely 

 elliptical, almost twice as wide as long, not quite one-fifth wider than 

 the 1st. Seen in profile, the pro-mesonotal portion of the thorax is 

 much less convex than in Constanciae. Otherwise like that species. 



$ . 3 - 6 mm. Pronotum very short in front, more exposed at the 

 lateral angles. Mesonotum longitudinally rugose, slightly convex in 

 front, flat posteriorly. Scutellum moderately convex. The sculpture, 

 especially on the abdomen, is a little stronger than in the <J . Wings 

 tinged with yellow, nervures and stigma pale brownish-yellow. Other- 

 wise like the ^ . 



$ . 3 mm. Black legs, antennae and mandibles dirty yellow, 

 femora brownish-yellow. Pilose hairs trifid, much less abundant but 

 longer than in the $ . Mesonotum very sparsely pilose. The hairs 

 on the head short, not branched. Head slightly shining, reticulate- 

 rugose. Mesonotum smooth and shining. Scutellum and nodes 

 slightly shining and feebly rugose. Epinotum unevenly reticulate- 

 rusfose and dull. Abdomen smooth and shining. 



Head subquadrate, about as long as wide, the posterior angles 

 widely rounded, the posterior margin convex, higher behind than in 

 front. Eyes large, occupying about one-thh-d of the sides, placed a 

 little in front of the middle ; ocelli small. Scapes a little longer than 

 the 2nd joint of the flagellum. Mesonotum very convex in its anterior 

 half, somewhat flattened above posteriorly. Mesonotum and scutellum 

 much higher than the epinotum. The latter is unarmed, and its upper 

 surface forms a continuous and steep slope from base to apex, the 

 dorsum and declivity not differentiated. The 1st node, including its 

 articular portion behind, as long as wide, much narrower than in 

 the $ ; 2nd node transversely oval, one-quarter wider than the 1st, half 

 as wide again as long. Wings as in the $ . 



Hillside, Bulawayo; Matopo Hills, S. Rhodesia. (S.A.M., E.M. ? 

 Gr.A. colls.), types in my collection. 



This species, like the foregoing, has been found by me only on the 

 granite and syenite formations. The Hillside locality, near Bulawayo' 

 is a syenite area, which rises like a small island out of the surrounding
