Male. White. Palpi and antennae ochraceons. Thorax with three 

 ochraccous bands ; tegulae ochraceous. Abdomen whitish, testaceous 

 towards the tip, which has a large tuft. Legs with ochraceous bands. 

 Fore wings with four ochraceous bands; 1st near the base, rather 

 irregular ; 2nd broader, emitting a broad streak to two black dots, one 

 of which is behind the other; 3rd band slightly undulating; costa 

 with a recumbent fringe, which extends from the 2nd to beyond the 

 3rd band, and is marked with ochraceous opposite these bands. Hind 

 wings tinged with pale yellow ; interior border thickly and deeply 

 fringed. Length of the body 8 lines; of the wings 18 lines. 

 This species may be distinguished from the preceding one by its stouter 

 form, the broader and differently formed bands of the fore wings, by the 

 difference in the discal dots, and by the longer costal fringe.

Male. White. Palpi and antennae ochraceous. Thorax with three 

 ochraceous bands ; tegulae ochraceous. Abdomen ochraceous at the 

 tip. Legs with ochraceous bands. Fore wings with four ochraceous 

 bands ; 1st band near the base, emitting a streak to the 2nd, which 

 consists of two parts ; 1st part forming a widened continuation of the 

 streak ; 2nd part clothed with long hairs, extending obliquely to the 

 costal fringe ; 3rd band broad, abbreviated in front, blackish-bordered 

 on the outer side; 4th broad, marginal; recumbent costal fringe 

 ochraceous, extending from the 1st to the 4th, with two white bands, 

 of which the 2nd is abbreviated hindward. Hind wings slightly tinged 

 with ochraceous, which hue is most prevalent towards the tips. Length 

 of the body 6 lines ; of the wings 16 lines. 



This differs more from the two preceding species than the latter do from 

 each other ; but the three form a distinct group in the genus.
