Notes on South African Mutillidae. 347 



erect greyish airs, sculpture of the first two segments similar to that 

 of the female but a little finer, the other segments finely punctate, 

 pygidial area punctate and slightly striolate, first segment with a 

 somewhat short carina truncate at each end on the ventral side ; legs 

 clothed with white hairs, hind tibiae simple, spurs white. 



Length 10 mm. ; expanse of wings 15 mm. 



Hab. Natal (Umhlali), K. S. Barnard. 



Allied to J/. psammathe, Per., and the livery is the same, but it 

 differs in the shape of the head which is quadrate on the vertex 

 instead of being narrowly transverse, the genal space being nearly 

 as long as the eyes themselves which are emarginate, and the base is 

 slightly arcuate instead of being straight ; in this character it 

 resembles M. petrusiana, Per., in which the wings are hyaline for 

 half the length, and fuscous for the remainder, instead of being entirely 

 fuscous as in M. psammathe. But the lateral lamelliform carina of 

 the scutellum is a distinctive feature of the genus Odontomutilla, 

 and I shall therefore include it in spite of the rounded sides of the 

 metanotum, the shape of which is that of Mutilla. My example was 

 caught the same day and in the same locality as a 5 of M. ceto, 

 Per., said by Andre to be the same species as M. rufipcs, Fabr. 



ODONTOMUTILLA CHIBUNGA, sp. n. 



$ . Black, with a proiiotum and mesonotum red ; abdomen with 

 a pubescent white band on the border of the second segment, 

 narrowly interrupted in the centre, and a whole one on the third. 

 Head as broad as the pronotum, transverse, straight behind, genae 

 long, hind angles not rounded, eyes large, deeply emarginate, surface 

 clothed with a greyish pubescence ; antennae robust, third joint 

 short ; pronotum straight in front with the angles sharp, mesonotum 

 convex, scutellum sharply dentate on each side at apex, slightly 

 emarginate in the centre, metanotum gradually ampliated diagonally 

 laterally towards the apex which is very sharp, the surface is foveate 

 reticulate and greyish villose on the pronotum, mesonotum, and 

 scutellum, the latter has at apex a fascicle of white hairs, the broadly 

 reticulate metanotum is villose white ; tegulae red, wings fuscous 

 with the basal part briefly hyaline ; abdomen sessile and clothed 

 above with white hairs, the first segment bears no trace of white 

 band or patch, and the carina underneath is in the shape of a sharp, 

 triangular compressed tooth, the second segment is covered with 

 closely set sub-reticulate punctures in the first half, the punctures 

 assuming an ovate shape without reticulation in the posterior part ;
