The upper side of the four wings is brownish-black, having towards the margin an arched band of violet-coloured white spots, of which the greatest is at the extremity of the wing.

There is also on the superior margin, about the middle of the upper wing, a white point, and at its inferior angle a marginal series of a few white points.

The upper side of the lower wings has an abbreviated series of marginal points on the outside of an arched series of violet-coloured whitish lunulae.

The underside answers well to the description given by Godart of the underside of his Danais eunice, except that D.darchia has only one white point in the middle of the upper wing.
This species bas been named by Captain King after his friend Thomas Darch, Esquire, of the Admiralty.
