This species is the local representative of aS'. Imeatus Fahr., 

 which occurs commonly in Matabeleland and which may be 

 distinguished from it by the following characters : — Its more 

 prominent eyes ; the entii-e absence of the orbital projection 

 behind the eye ; the prothorax is distinctly narrowed towards the 

 base, being broadest close to the apex ; and finslly the oblique 

 rostral furrows unite at the base. 



Steophosomus binotatus (Fst. in Hit.), sp. nov. 



Long. 8-8|, lat. 4|-4| mm. 



Colour black, with opalescent grey scaling which is paler and

The narrowness of the shoulders gives this insect a somewhat 

 characteristic pear-shaped facies. It is allied to ;S'. lineatus Fahr. 

 and S. salishuriensis Mshl., both of which difier from it in havinsr
