The genus, as defined by Brunner, is chiefly of South African 

 habitat, one species only being recorded doubtfully from Java. 

 In the British Museum Catalogue, Walker records, p. 231, 

 " Einlamjjra irrorata, Thunb., nov. spec. I., 76 ; Fabricius, Ent. 

 Syst. II., 8," from Australia in three instances. Referring to 

 Brunner's record of the literature quoted. ^E. irrorata'' is not 

 mentioned at all, but the pages cited quote Blatta erythrocejjhala, 

 Fabr. (Ent. Syst., II., p. 7 and 8), while B. capensis, Thunb. 

 (Dissert. Ent., 77) is mentioned as a synonym of the former. 

 Whence Walker obtained the name " irro7'ata " is not apparent, 

 but most likely another synonym for B. erytlirocepliaUis, Fabr. 

 As I am not in a position to prove his localities wrong, I insert 

 the genus on his authority.
