The fore-wings are nearly alike in both sexes, the outer margin 

 being scarcely emarginate. The general colour is uniform obscure 

 yellowish grey, covered with minute black irrorations ; at the distance 

 of about one-third of the length of the wing from the base is a rather 

 narrow white transverse striga, slightly angulated outwardly, having 

 a dusky edge on the inside next the base of the wing. In the middle 

 is a rather small ocellus, the centre being semi-oval and vitreous, edged 

 with fulvous, and surrounded by a thin black circle; this is surrounded 

 by a dull buif ring, and this by a white one ; beyond the middle is 

 an oblique nearly straight white striga, nearly parallel with the outer 

 margin, outwardly edged with a dark brown line. Hind-wings pale 

 livid pink at the base and along the anterior portion ; near the base 

 is an obscure white striga, and in the middle is a large oval ocellus, 

 coloured in the same manner as the ocellus of the fore-wings, and 

 followed by a curved white striga edged outwardly with brown. 



The thorax is coloured as the fore- wings, with a narrow transverse 

 white ring across the front. The abdomen is more strongly fulvous- 

 coloured. Wings beneath grey, the fore-ones tinged with pink on the 

 inner margin ; across the middle is a fulvous cloud ; the basal fascia 

 and the eyelet of the hind-wings are wanting. The veins are arranged 

 in the typical manner. 



The male antennae are 35-jointed with fifty-six rays on each side, 

 the rays rather long ; the two basal rays of each joint are obliquely 

 porrected, so that the rays form four series instead of all being on the 

 same plane ; the six apical joints minute and not producing rays. 

 The antennae of the female are setaceous, the rays being scarcely 

 visible without a lens. The palpi are flattened, short and deflexed.

Male with the fore-wings entire, and slightly rounded along the 

 outer margin. General colour yellow ; fore-wings finely powdered 

 with small brown scales, having a slender, angulated, brown striga 

 before the middle, slightly tinged on the outside with rosy ; in the 

 middle of the wing is a large eye, having a subovate vitreous centre, 

 surrounded by a broad dirty luteous brown ring, succeeded by a 

 narrow black circle with a white outer ring ; halfway between this 

 and the outer margin is a narrow brown striga parallel with the outer 

 margin, inwardly edged with rosy white. Hind- wings rosy yellow at
