half the length of the forewing; forehead tufted; thorax probably crested, 
but denuded in the specimen under description; abdomen not extending 
beyond the hindwings, crested and villose towards the base, upper side 
luteous shading into ferruginous grey at the base ; legs rather long, anterior 
tibiæ very densely clothed beneath with long flexible hairs, the intermediate 
tibie with one, and the posterior with two pairs of long spurs. 
Forewings.—Upper side appear to be pale ferruginous-grey, clouded 
with ferruginous brown and purplish-grey markings, but are too dilapi-

thirds luteous with a black band across the middle and the appearance of a 
broad dark marginal band. 
Hindwings.— Upper side luteous, brownish at the base, with a very broad 
curved and abbreviated discal black band or patch, concave outwardly, and 
a broad black outer border abbreviated towards the anal angle, and ending 
opposite the hind end of the discal band. Under side similar to the upper 
side, but rather paler.
