brown, preceded by a paler patch marked with undulating fulvous- 

 brown lines ; the hind-angle of the wing being much dotted with dif- 

 ferent shades of fulvous and brown. The hind-wings have a large 

 sulphur-white patch occupying the base of the wings, except the 

 extreme base, which is pink. The remainder is brown, varied with 

 minute fulvous spots, the anal angle being more mottled. 



On the underside the wings are paler and richer coloured, more 

 decidedly mottled ; the fore-wings having the base suffused with pink. 

 The veins are fulvous. 



The antennae are but slightly pectinated. 



The body is fulvous-brown, the thoracic portion tinged with pink.

A single specimen only of this insect exists in the British Museum, 

 having the wings so completely denuded of scales, except at the base, 

 that it is impossible to give a detailed charater ; their outline is how^- 

 ever entire. The anterior ones are subfalcate, and the hind ones are 

 denticulated along the outer margin, the tooth at the extremity of 

 the middle branch of the median vein being the most acute. All that 

 remains of the colouring of the fore- wings is a reddish-fulvous buff, 

 which seems indeed to have extended all over these wings, as well as 

 over the hind-wings, which are sufPused with pink on the upper side 

 towards the anterior margin. On the under side the wings are co- 

 loured as above ; the fore- wings are also suffused with pink along the 

 posterior margin at the base, and they, as well as the hind-wings, have 

 the anterior margin somewhat streaked transversely with brown. I can 

 discern no trace of eyes in the middle of the wings. The body both 

 above and below is fulvous brown, as are also the antennae and legs. 



The basal joint of the antennae is clothed beneath with a thick 

 mass of hairs ; each is furnished with eighty rays, each of the twenty 

 joints succeeding the basal one emitting four rays, one close at the 

 base and one close at the apex on each side, the inside of the two on 

 each side being furnished with fine hairs, the tips of which come in 

 contact with each other. The thirteen terminal joints are destitute 

 of rays. The palpi are quite distinct, but scarcely extend beyond the 

 hairs of the face.
