wanting. The $ resembles the ^ but the ground-colour is dull 

 chocolate brown, and the abdomen is black with large white 

 lateral spots and white segmental rings. 



Much confusion has arisen over this species, doubtless 

 owing to its rarity and the comparative inaccessibility of 

 the original figure. I have therefore prepared a figure of 

 the ^ from an example in the Tring Museum which agrees 

 with the figure given by Reiche {I. c), and have also 

 illustrated the Arabian subspecies which I found in the 

 same collection. Four ^^ and one ^ of this form were 

 taken in the Azvaki Ravine in Southern Arabia. The 

 A. douMedayi described in Trimen's S. African Butterflies 

 is A. oncaca, and hence many examples of the latter 

 species are labelled douhlcdayi in collections.
