Stenomutilla dolichoderoides, new species. 



Female.— Entirely black;withacontinuous.apical band of yellowish 

 white hairs on the first and second tergites and a fringe on the se- 

 cond sternite; the band on the second tergite broadened medially. 

 Calcaria black. A long, slender species. 



Length : 9,5 mm. 



Head and dorsum uniformly, very coarsely and closely punctured. 

 Head prolonged behind the eyes, the margins strongly converging; 

 médian part of posterior margin prolonged into a rim over the neck. 

 Clypeus with a superior, elevated portion, narrow and bordered on 

 each side by a raised margin ending above between the antennae in an 

 acute angle and terminated below by a smooth and polished trans- 

 verse lobe; below this a transverse, elevated ridge runs ail the way 

 across the clypeus; this ridge is somewhat interrupted by a médian 

 emargination in the center of which is a small lobe.Mandibles slender, 

 acute. Antennal grooves without superior margin. Thorax widest in 

 the middle; strongly narrowed both anteriorly and posteriorly; ending 

 in front in a transverse neck, the anterior margin of which is slightly 

 reflexed. First abdominal segment slender, with its apex about one- 

 third the maximum width of the second; its under side with a médian 

 ridge, but without distinct teeth. Second sternite swollen at base; 

 this swelling commencing on the sides with a ridge which runs for- 

 ward from the felted grooves. Second tergite closely and coarsely 

 punctate, a little bit more sparsely on the sides. Ultimate tergite with 

 the médian and apical portion impunctate and polished. 



Habitat : Tanganyika Territory, one female, Kigoma (R. Mayné). 

 Holotype : Congo Muséum, Tervueren. 



This species would run to congoana in Bischoff's key, but the 

 clypeus is of a différent shape, the first abdominal segment much 

 more slender, and the thorax more elongate. It is also close to kohli 

 Bischoff, but Bischoff's figure shows for that species a stouter first 

 segment of the abdomen as in congoana.
