This fine species was first described by Mr. White in the Appendix to Captain Grey’s Narrative.  He then expressed the opinion that it was nearly allied to Castnia and Coronis.  The generic characters given above will fully justify this view.  In fact we can only regard it as the Australian representative of Castnia.

The under surface of this species is beautifully varied with black and orange, but I may refer for a more detailed account to the work above mentioned.
