Geographical distribution. The types are from Kakonda 

 (Caconda) and Kwaugo in Angola ; I hate seen three speci- 

 mens perfectly identical with the types from Salisbury, 

 Mashonaland (B.M. and O.M.).

The description of this species leaves no doubt that it 

 belongs not to Phyxacra but to Acridoderes. It seems to be 

 fairly distinct from A. crassus, though the colour-characters 

 given by Rehn are not quite reliable owing to the preserva-

The original description enables me to conclude that the 

 species belongs to Acridoderes and is sufficiently distinct 

 from the two others known. It is omitted from Kirby's 

 Catalogue altogether.

 am correct in referring three insects from the Transvaal to
