Hab. NATAL. Izezela (Sweeney). Umkomaas (Burnup). 

 Also known from Mauritius and Madagascar. 



Nevill (1884) writes : "I think 1 may state positively that 

 Deshayes' If. moreleti is the young of the typical form " (amarula), 

 " notwithstanding the remarkable ' quasi ' adult appearance that it 

 invariably presents." 



It is questionable whether the Natalian examples should be attri- 

 buted to amarula or to the following species.
