falcate, edentate. Thorax in dorsal aspect short, broad; the anterior half 

 or two-thirds subquadrate, with its latéral sides slightly convex; behind 

 that point deeply and suddenly incised in an even curve to the angles 

 cf the propodeum, so that the entire thorax in dorsal view appears 

 angulately piriform. Each angle of the propodeum with a minute den- 

 ticulation, behind which the propodeum is obliquely truncate. The 

 entire dorsum is homogeneous in appearance, uniformly, transversely 

 convex, with distinct, medium-sized punctures, but medially with 

 an impunctate, polished band; the cephalic slope of the pronotum 

 closely punctulate; the truncature of the propodeum indistinctly 

 punctulate and its sides aciculate. First tergite of the abdomen seen 

 from above with almost parallel sides; slightly widened before, but 

 again narrowed at the apex, which is both somewhat constricted from 

 and much narrower than the second tergite. Seen from the side the 

 first segment is anteriorly flattened, widest at a point two-thirds the 

 way to its apex and again narrowing at the apex; the latéral view thus 

 forms a triangle of which the under surface is the base. The anterior 

 flattened portion of this segment is impunctate at base, weakly punc- 

 tured posteriorly, the posterior surface is rugose and margined at 

 apex and on the apical portion of the sides. No felt grooves on either 

 second sternite or tergite. Second tergite very long, nearly equal in 

 length to the remaining segments together; its surface anteriorly 

 rugosely punctate; posteriorly shiny; sparsely and weakly punctured. 

 Following three tergites finely, closely punctulate. Pygidial area very 

 long and narrowly oval with about four sharp, longitudinal strise. 



Habitat : Portuguese East Africa, one female from Catamba, Lou- 

 renzo- Marques (C. W. Howard). 



Allotype : Cornell University, No. 657.1. 



This female was obtained together with a maie, presumably in 

 copula, the two spécimens being placed on the same pin. The maie 

 agrées with the description of Rhopalomutilla anguliceps (André). 

 The female also possesses the generic characters assigned to the fe- 

 male of Rhopalomutilla by André. The identical female upon which 

 Bischoff based his generic description and which he identified as 

 clavicornis André, lies before us. It differs not only from our female
