Hiibner's figures of this species do not at all do justice to its great beauty. Nothing can 

 exceed the brilliancy of the underside of the posterior wing. It is of a deep crimson irrorated 

 throughout with golden green, gorgeous from the base to the central band ; the inner border of 

 the said band of the outer margin, as well as the fringe of the margin and of the tails, is bright 

 silvery lilac.
