(^ . Upper side : Pearly white, broadly margined with dense 

 black, clouded at base. Primaries, costa, apical region, outer 

 margin, and hinder angle, black, the black extending from ex- 

 tremity of cell, in a curved line to hinder angle, where it termi- 

 nates in a moderately wide band ; subapical curved row of three 

 (sometimes fom-) white spots, largest towards apex. Secondaries 

 with broad black outer marginal band in a straight line across wing, 

 enclosing apical and anal angles, embracing about one-third of 

 whole wing ; in some specimens with three or four marginal white 

 points between the nervures. Under side : The black of rich pur- 

 plish hue ; base of both wings sulphm'-yellow. Primaries with 

 black marginal band not extending to hinder angle ; subapical row of 

 spots larger, and extending much fm-ther down the wing ; first three 

 bright yellow. Secondaries with only costal area and small portion 

 of cell white ; submarginal band of wide crescent-shaped marks 

 from apical to anal angle ochre-yellow. Thorax grey. Abdomen 

 white. Expanse, 2j^j — 2-^ inches.

The nearest ally of this species, as far as I am able to 

 determine, is D. Ennia, Wallace, from which, however, it 

 is well distinguished, but to which it bears about the 

 same relation as does our Mijsis to Bagoe, Boisd. 



My specimens, all captured by myself, are females ; 

 the male is at present unknown.
