sharply bidentate. Mandibles without an external tooth, somewhat 

 bent, slender and acute, with an inner tooth. Scape carinate, punc- 

 tured on the inner side. Second segment of flagellum subequal to 

 the first and much less than the third in length. Thorax slender, with 

 the sides converging anteriorly and with rounded humerai angles. 

 Pronotum and mesonotum uniformly, coarsely and deeply punc- 

 tate, a little more coarsely than the vertex; anteriorly in the middle 

 the mesonotum bears an impunctate, flat band with latéral longi- 

 tudinal strias. Parapsidal furrows absent anteriorly. Scutellum round- 

 ed, convex, sculptured like the mesonotum. Propodeum reticulate, 

 with large, flat meshes; a distinct, triangular, basai area présent; its 

 posterior face sloping and its angles rounded. Third transverse cub- 

 ital vein lacking; a spot of chitin in the wing membrane representing 

 its position; second transverse cubital vein with a short appendage. 

 First sternite with a médian keel, which is most prominent posteriorly, 

 but nùt acute. First tergite with sides converging anteriorly; at its 

 apex much narrower than the greatest width of the second segment, 

 but not constricted therefrom. First and second tergites uniformly, 

 coarsely punctured; the punctures about as coarse as on the vertex. 

 Remaining tergites finely and closely punctate. Pygidial segment 

 flat, punctate laterally and basally; impunctate, smooth, and polish- 

 ed medially and at apex. Apex broadly rounded. Last sternite punc- 

 tured, but unarmed. 



Habitat : Belgian Congo, one maie, Lanuri Valley, western slope 

 of Mt. Ruwenzori; altitude, 2000 m.; May 24, 1914 (J. Bequaert). 



Holotype : Congo Muséum, Tervueren. 



This species seems to find its closest ally in Squamulotilla cerenipes 

 Bischoff, found on similar altitudes on Mt. Kokanjero, in Uganda. 

 Apart from its entirely black color with yellow legs (instead of rust 

 yellow thorax), it may be most easily distinguished from that species 

 by the coarse puncturation of the second tergite, by the triangular 

 basai area of the propodeum, and by the absence of a small médian 

 tooth in the emargination of the edge of the clypeus.
