e, tufted at its extremity, in the
female tapering to a point.

There seems to be a slight difference in the structure of the antennae in
this genus, in the first species the club is rounder and less mucronate
than in the two following ones, it seems also destitute of the tuft of
scales at the point.

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

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.
