Some Ncio or Little Known South African Mutillidce. 39 



? Thorax subhexagonal, median part aculeate, anterior part not 

 incised, or hardly so laterally, posterior part one-third narrower at 

 base than the apex, declivity subtruncate, sides of thorax not 

 serrulate, first abdominal segment subelongate, petiolate ; tibise 

 with one or two submedian spines bands. 



? Thorax truncate and serrulate at apex, straight laterally from 

 one-third of the length and tridentate, attenuated from there to the 

 declivity in the shape of a broadly truncate cone, outer sides cari- 

 nate and serrulate to the very base, declivity abrupt latona. 



? Thorax long, straight laterally, but with the posterior part 

 narrowed but also straight, abdomen oblong, first segment as wide 

 at apex as the base of the second, which is very slightly ampliate 

 in the middle aglae. 



? Thorax truncate at apex, parallel laterally for one-third of the 

 length, and with four short teeth, narrowed from there to the 

 declivity, which is very abrupt, sides serrulate, abdomen pyriform ilytliia. 



b 1 . Bands triangular on the first and second segments. 



? Thorax deeply incised laterally at about one-third of the 

 length, parallel from there to the perpendicular declivity, deeply 

 foveate with the intervals distinctly carinate from apex to base ; 

 head striolate, first basal segment entirely covered by a triangular 

 patch, that of the second segment produced triangularly towards 

 the median part which it does not reach callirhoe. 



? Thorax similar in shape to that of J/. callirlioP, but not so 

 deeply foveate, and with the intervals also raised but not carinate 

 longitudinally, first basal segment with a narrow apical band ; head 

 with two distinct ocelli glance. 



? Thorax similar in shape to that of the two preceding species, 

 and similar in sculpture to that of M. glance; band on first 

 abdominal segment broadly triangular, that on the second segment 

 produced in a broad triangle, the point of which reaches the median 

 part ; head without ocelli electra. 



a 6 . The three first basal segments of abdomen banded, band on 

 third segment interrupted in the middle. (No female.) 



I. 

 C 1 . ABDOMEN SESSILE IN BOTH SEXES. 



Thorax incised laterally at a short distance from the apex, parallel 



from there to the declivity which is perpendicular, deeply 



foveate with the intervals carinate. 



? Head not quite as broad as the thorax, dark with a small 

 ferruginous round patch on the vertex, pubescent baud of abdomen 

 white callisto.
