This species finds its closest ally in O. mocquerysi (André), from 

 which it differs in the shape of the scutellum and in the absence of 

 the pubescent spots on the first tergite, and somewhat in the shape 

 of the clypeus. 



Odontomutilla microcephala André. 



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



Odontomutilla mocquerysi (André). 



Cameroon : Metit, one female (A. I. Good. — Carnegie Muséum). 



Odontomutilla tellini (Magretti) var. tessmanni Bischoff. 



Belgian Congo : one maie, Angu (Uere). November io-n, 191 3 

 (J. Rodhain); one maie, Bambili (J. Rodhain) (Congo Muséum). 



Thèse spécimens agrée in every respect with Bischoff's description. 

 In tessmanni the first sternite has posteriorly a very small tooth, 

 anteriorly a strong, acute spur the two not connected by a carina. 

 Magretti describes his tellini as having on the first sternite an elevated 

 carina, armed with a moderate rostriform spine. In so many respects 

 does tessmanni apparently differ from tellini that it most probably 

 is specifically distinct; but this can only be decided by a comparison 

 of the two. 



Odontomutilla natalensis Bischoff. 



Natal : two maies from Durban, in the collections of the American 

 Muséum of Natural History. 



Odontomutilla callewaerti, new species. 



Maie — Black; tegulae rufous. Apex of first tergite on each side with 

 a spot of white hairs; third and fourth tergites with broadly interrupted 

 wide apical bands of white pubescence. Wings of type spécimen bro- 

 ken off. 



Length : about 15 mm.
