Body stout. Wings ample, each with an ocellus, whose disk is 

 partly or wholly vitreous. Fore wings very generally more or less 

 falcate ; costa more or less convex towards the tip ; exterior border 

 generally more or less undulating. Hind wings as long: as or 

 longer than broad, very little broader than the fore wings, extending 

 more or less beyond the abdomen. 



The principal characters which distinguish this group from 

 Attacus are the greater size of the abdomen, the different colouring 

 of the wings, the less development of the hind wings, and the 

 vitreous spot, which has another form.
