This Butterfly, which measures rather more than two inches 

 and a half across the wings, is common in Australia, Papua, 

 Amboina, and Ceram. It is the type of Hiibner's genus, 

 Cathamia^ which he regarded as distinct from true Delias. 



The male is bluish-white above, with a black border, broadest

 spots on the fore-wings, as in the male. The under side is
