distance, the band on the third segment is a little wider than the 

 one preceding, and interrupted in the middle for about one-third 

 of the distance from side to side, the other joints are without any 

 trace of lateral yellowish white pubescence ; tibiae with a double 

 series of spines ; ventral carina of first abdominal segment short, not 

 prominent, sub-truncate at base. Length 12 mm. 

 Hab. Cape Colony (Worcester, Port Elizabeth). 



MUTILLA TECMESSA. 



Female. Nearly similar in shape and structure to M. callisto, 

 but the head is broader than the base of the thorax ; upper part of 

 the head and thorax bright red instead of black ferruginous 

 red, the foveae, however, are a little broader, the abdominal bands 

 are bright orange, and the one on the second segment a little 

 broader and more triangular in the middle. Length 11-13^ mm. 



Male. Head quadrate, with the posterior angles sharp, twice as 

 wide as long on the vertex, shagreened, pubescent, black ; eyes 

 slightly emarginate ; thorax black, with the prothorax and mesothorax 

 and also the scutellum red, tegulae red, upper part very rough and 

 with two very distinct longitudinal median grooves ; metathorax a 

 little attenuate and rounded laterally behind ; abdomen subsessile, 

 black with a faint, dark cyaneoiis tinge, closely but not deeply 

 punctured on the dorsal part, bands of the same colour as those of 

 the female, and similarly disposed ; ventral carina of first joint 

 sharp and sloping at both ends ; tibiae non-spinose ; wings sub- 

 hyaline at base, slightly infuscate from there to the apex, anterior 

 margin of fore wings more deeply infuscate at equal distances from 

 base and apex. Length 11-J mm. 



Hab. Cape Colony (Clanwilliam), both sexes ; Port Elizabeth, 

 male and female. 



Although not actually captured in coitii, I think there is little 

 doubt that the two sexes here described are the same species. 



MUTILLA HELLE. 



Female. Discoidal part of the head and upper part of thorax ferru- 

 ginous red ; antennae, legs, and abdomen black ; head very broad, 

 nearly as wide as the second abdominal segment at its widest, ampliated 

 behind the eyes, which are small and ovate, closely but not deeply 

 punctured, hairs moderately dense and black, mandibles long, falci- 

 form, widely bifid at tip and with a sharp, erect process on the upper 

 margin ; thorax truncate at apex and with the apical angles very short, 

 narrowed diagonally laterally from the anterior angle to one-fourth 

 of the length, bisinuate from there to the posterior angle, the median
