Genus AXIOCERSES Hiibner 



Axiocerses Hiibner, 1826, Verz. bek. Schmett. : 71 ; Aurivillius, 1898 : 334 ; 1924 : 419 ; 

 Murray, 1935 : 91 ; Pinhey, 1949 : 105 ; Swanepoel, 1953 ; 162. Type-species : Papilio 

 perion Stoll, 1781 (i.e. Papilio harpax Fabricius, 1775), by monotypy. 



Chrysorichia Wallengren, 1857, Rhop. Caffr. : 44. 



In 1857 Wallengren [Rhop. Caffr. : 44) erected the genus Chrysorichia for what he 

 regarded as two species, which he called thyra Linn and tjoane sp. nov. These, 

 according to Aurivillius, who had access to the type specimens, were in fact the male 

 and female respectively of the species now known as Axiocerses harpax Fabricius. 

 However, in 1875 Scudder selected " thyra Linn " as the type-species. According 

 to the present International Rules of Zoological Nomenclature, Article 70, a case such 

 as this, in which the type-species of a genus has obviously been misidentified, is to 

 be submitted to the Commission for a ruling. I propose therefore to invite the 

 Commission to designate Papilio harpax Fabricius as the type-species of Chrysorichia, 

 which will make that name an objective synonym of Axiocerses, and in the meantime 

 to regard Chrysorichia as such. 



Eyes glabrous ; frons clothed with erect hairs ; palpi rather short, parallel, hardly protruding 

 beyond the frons, second segment clothed with erect scales and hair, third segment short, 

 acuminate, slightly ascending ; antennae more than half the length of the costa, white-annulated, 

 club cylindrical, well differentiated ; thorax robust, clothed above with long silky hair and 

 below with close woolly hair ; <$ fore leg very robust, tibia as long as femur, both densely
