marginal band narrower than the one on the third segment which 

 clothes it entirely ; ventral carina of first segment, short, sinuate, 

 sharply aculeate at apex, second one with a distinct median carina 

 reaching from the base to the median part ; tibiae without spines ; 

 wings totally infuscate. Length 13 mm. 

 Hab. Zambesia (Umfuli River). 



MUTILLA PROSERPINA. 



Black, with the thorax bright red, and the spots and bands 

 on the abdomen sub-flavescent ; head transverse, nearly straight 

 laterally, arcuate behind, twice as broad as the thorax, roughly and 

 closely punctured, frontal tubercles distinct, eyes set forward ; thorax 

 without any noticeable suture between the prothorax and niesothorax, 

 tegulae very small, almost rudimentary, no wings, scutellum hardly 

 defined, metathorax ampliate, as wide as the prothorax, rounded 

 laterally behind ; abdomen sub-pyriform, sub-sessile, second seg- 

 ment with two median rounded spots equidistant from base and 

 apex, third segment with a sub-flavescent band, apical segment 

 pubescent, and spines long ; ventral carina of first segment truncate 

 at both ends ; tibiae with a double series of spines. Length 3 mm. 



Hab. Cape Colony (? Beaufort West). 



The general appearance is that of a female with thorax constricted 

 laterally in the median part ; the almost rudimentary tegulee tend

 have, however, seen one example only. 



MUTILLA ERINNYS. 



Male. Black, with the prothorax, niesothorax and the scutellum 

 red ; head moderately small, scrobiculate, transverse on the vertex, 

 with the eyes distinctly eniarginate ; prothorax and mesothorax 

 foveate, tegulaB of the same colour, mesothorax without any longi- 

 tudinal grooves, scutellum distinctly carinate laterally, the carinse 

 projecting in a sharp tooth beyond the median part which is declivous 

 and has a narrow 7 incision in the middle separating it in tw r o short 

 lobes, metathorax with two deep, broad, smooth depressions close to 

 the post-scutellum, declivous at base w r ith the posterior angles pro- 

 duced in a long carinate and triangular process ; abdomen sessile, 

 closely punctured, the punctures on the second segment not so closely 

 set and leaving a narrow, nearly smooth median interval with a 

 narrow, longitudinal line, first segment with a quadrate, sub- 

 lateral white patch, third and fourth segments w r ith a moderately 

 broad band extending on each side from the side to two-fifths 

 of the width ; this band is, however, narrower on the fourth 

 than on the third segment ; ventral carina of the first joint in
