Some New or Little Known South African Mutillidce. 75 



laterally behind, eyes large, mandibles bifid at tip ; thorax incised 

 laterally at a short distance from the apex, which is nearly straight, 

 narrower and parallel from there to the declivity, which is perpen- 

 dicular and has nine sharp teeth on the upper margin, disk with 

 seven longitudinal but wavy ridges in the median part and two 

 lateral series of scrobiculations on each side ; abdomen sub-sessile, 

 first segment with a small median white patch, second one covered 

 with elongated, longitudinal raised lines, and having two supra- 

 lateral, ovate white patches and a small, apical, median one ; third 

 segment clothed with a white band ; tibiae with a double series of 

 spines. Length 14 mm. 



Very closely allied to M. arsinoe ; differs by the sculpture of the 

 thorax, the dorsal part of \vhich is covered with much more distinct 

 and less undulating carinse, the upper margin of the declivity is also 

 more distinctly dentate ; but the two species may prove to be one. 

 I have seen only one example of each. 



Hab. Zarnbesia (Umfuli Kiver). 



MUTILLA ARTEMIS. 



Female. Black, \vith the dorsal part of thorax ferruginous ; head 

 as broad as the thorax, eyes moderately small and placed very 

 much forward, sides arnpliated laterally, moderately rounded in the 

 posterior angles, base truncate, scrobiculate, with the intervals 

 raised and linear in the posterior part, clothed with a very brief 

 flavescent pubescence, and with long, black, moderately dense 

 bristles ; thorax broad, short, nearly as wide as long, slightly sloping 

 on each side at apex, incised laterally but not deeply at a short 

 distance from the apex, nearly straight from there to a short 

 distance from the base, where it is a little broader than the anterior 

 part, and slightly narrow-ed from there to the declivity, which is 

 perpendicular with the sides denticulate, the disk has eleven very 

 distinct, slightly undulating ridges reaching from apex to base ; 

 abdomen sub-sessile, pyriform, second segment distinctly striolate, 

 spots on the first and second segments and band on the third, as 

 in M. hecatc ; ventral carina truncate at apex and obsoletely tri- 

 dentate ; tibiae with a double series of spines. Length 11 mm. 



Allied to 1\I. hecate and M . parca, but differs from the first in the 

 striolate head and broader thorax, the longitudinal carinae of which 

 are more numerous, the abdomen is also more pyriform ; from M. 

 parca it differs by the smaller head, less parallel thorax, and non- 

 dentate upper margin of the declivity.
