with closely set, smooth, longitudinal raised lines reaching from the 

 base to two-thirds of the length ; the white spots on the first abdo- 

 minal segment are equidistant from the median and lateral parts, 

 and the band on the third segment is narrowly interrupted in the 

 centre ; the ventral carina of the first segment is sub-acute at apex ; 

 the tibiae have a double row of spines. Length 9-10 mm. 



Hob. Bechuanaland. 



This species resembles also M. horrida; it is, however, smaller 

 and more slender than the smallest examples of M. horrida which I 

 have seen, and the abdomen is more pyriform. 



MUTILLA CLOTHO. 



Female. Head, antennae, abdomen, and legs black, thorax ferrugi- 

 nous red, body clothed with long hairs, sub-flavescent on head and 

 thorax and beneath, black on dorsal part of abdomen ; head one- 

 third narrower than the thorax, straight laterally with the posterior 

 angles not rounded, base not quite straight, scrobiculate, briefly 

 pubescent ; thorax scrobiculate on the dorsal part with the intervals 

 raised, apical margin sloping slightly from the median part to the 

 anterior angle, straight laterally from there to about one-third of the 

 length, where there is a conspicuous, triangular tooth, and slightly 

 attenuate past the sub-median tooth to the posterior part, the angle 

 of which is very long and triangular, posterior declivity perpendicular ; 

 abdominal segments very densely hairy, aciculate with the exception 

 of the second which is covered for two-thirds of the length with 

 elongated, narrow punctures with raised intervals, the two sublateral 

 patches on the first segment and the broadly interrupted band on the 

 third one are whitish yellow, the sixth segment is clothed with dense 

 sub-flavescent hairs ; ventral carina of first segment sharp, truncate 

 at tip ; tibiae with a single series of spines. Length 19 mm. 



Facies of J/. horrida, and with the white spots and band on the 

 abdomen similar, but is easily distinguished by the long, triangular, 

 posterior angles of the thorax ; the intervals of the dorsal scrobicula- 

 tion are not longitudinal laterally, and the tibias have a single row of 

 spines instead of a double one. 



Hab. Transvaal (no exact locality). 



MUTILLA MEGAEBA. 



Female. Head and thorax ferruginous red, antennae, legs, and 

 abdomen black, body clothed with long hairs ; head closely foveate, 

 narrower than the thorax by one-third, straight laterally behind the 

 eyes, posterior margin slightly arcuate towards the posterior angles,
