Some New or Little Known South African Mutillidcs. 79 



truncate transversely behind with the posterior angles not rounded, 

 narrower than the thorax by one-fourth, very rough, and clothed with 

 a very brief, yellowish pubescence ; thorax truncate at tip, slightly 

 ampliate laterally from the anterior angle to a little short of the 

 median part, bi-sinuate and fad-dentate and a little narrowed from the 

 first lateral tooth to the declivity, where it is narrower than the apex 

 by one-fourth ; it is deeply foveate, the foveae closely set and with 

 raised, smooth intervals forming irregular, wavy, longitudinal ridges, 

 declivity perpendicular, serrate laterally ; abdomen sessile, first joint 

 truncate in front and with the sides parallel, and angular in the 

 anterior part, very rugose and with a sub-quadrate silvery white 

 patch on each side equidistant from the median and the lateral part 

 and overlapping slightly the basal edge of the second segment which 

 is strigose, third segment clothed with a white band broadly inter- 

 rupted in the middle ; ventral carina of the first segment incised in 

 the middle with the apical part dentiform, second segment with a 

 median raised line and a short depression on each side of the base ; 

 tibiae with one series of spines. Length 13-16 mm. 



Allied to M. ccplieus, Sm., and M. comparata, Sm. In shape and 

 size it very much resembles the former, but the head is smaller, and 

 the two white patches on the first segment are more distant ; from 

 M. horrida, Sm., which has similarly arranged white spots and bands 

 and also a head narrower than the thorax, it differs by the more 

 slender form, more elongato-ovate abdomen, and principally by the 

 transversely elongato-quadrate basal segment ; the tibiae have also 

 one series of spines instead of two, and the second segment is less 

 conspicuously strigose. 



Hab. Transvaal (Klerksdorp, Boksburg), Natal (D'Urban, Frere). 



MUTILLA CHIONE. 



Female. Head, antennae, abdomen, and legs black, thorax red, 

 body clothed with black and greyish white hairs ; head closely 

 scrobiculate, hardly pubescent, truncate behind, straight laterally 

 with the posterior angle not rounded, space between the base and 

 the posterior part of the eye small ; thorax a little broader than the 

 head, straight at apex with the angle sharp, nearly straight laterally 

 but a little narrowed gradually behind where it is about one-fifth 

 narrower at the declivity than at apex, irregularly serrate laterally 

 with one sub-median tooth better defined than the others ; it is 

 covered on the dorsal part with long, narrow, foveate punctures, 

 the intervals of which are raised in the form of longitudinal, wavy 

 lines more distinct from the apex to two-thirds of the length ; 

 abdomen sub-pyriforni, elongate, shagreened, second segment covered
