Notes on South African Mutillidae. 341 



from where it widens a little, being there as broad as the apical part 

 of the pronotum and moderately rounded at the base, deeply foveate 

 carinate, the slightly wavy carinules forming a distinct, sharp 

 serration at the top of the declivity, the sides of which as well as 

 those of the lateral hind margin are obtusely serrate, the declivity is 

 broadly recticulate, and the surface is covered with a greyish 

 pubescence ; abdomen sessile, second segment conspicuously 

 carinulate longitudinally, the carinules closely set and enclosing 

 ill-defined elongate fossulate punctures ; pygidial area finely 

 strigillate; legs bristling with white hairs; hind tibiae spinose, 

 spurs white. 



Length 8-9 mm.

The two yellow spots on the second abdominal segment are not 

 covered with pubescence, but are chitinous as in M. acrisione, 

 Pe>. The shape of head and thorax greatly differentiates this 

 species from the last-named species. Not only are the two orange 

 spots alike, but the sculpture of the second abdominal segment is 

 the same in both. 



MUTILLA MAMBA, Sp. n. 



5 . Black, with the thorax totally red ; abdomen with two ovate 

 flavescent patches on the second segment, equi-distant from the 

 sides and centre, on the third and fourth is a wide band of the same 

 colour broadly and equally interrupted in the centre ; hind border of 

 metanotum with seven horizontal conspicuous spines above the 

 declivity. A close ally of If. nais, P6r., whose description would 

 also nearly suit the present species, except that the thorax is less 

 parallel, being distinctly narrower at apex than at base and more 

 emarginate laterally from the well - defined high angles of the 

 pronotum to the third part of the length, the fourth abdominal 

 segment has also a wide pubescent band wanting in M. nais, and the 

 pubescent band and patches are flavescent instead of white. 



Length 9-10 mm.

MUTILLA MOGAMBA, sp. n. 



$ . Black, first and second abdominal segments red, the first 

 fimbriated with white at apex, the latter with a broad apical border, 

 third segment covered by a dense pubescent white band, pronotum
