cJ 13.5—15.5 mm. Head with a large rough blackish-brown flattened 
erect tuft on crown, collar greyish-fuscous; face deeply excavate, white, 
suffused with brown along edges above, with a projecting white tuft 
below. Palpus ochreous, median segment roughish above and beneath, 
suffused with brown, less suffused above and at apex. Antenna slightly 
serrate, greyish, ringed with blackish-brown, basal seventh strongly

ochreous. Thorax fuscous mixed with dark brown. Abdomen rather dark 
fuscous, paler anteriorly, anal tuft greyish. Legs deep ochreous, anterior 
and median tibia with a suffused brown basal, and a similar median ring,

fold, a fan of rough scales pressed against base from under side, projecting 
over edge of wing, base- of costa with a large raised brush of rough scales; 
costa little curved anteriorly, straight posteriorly, apex obtusely pointed, 
somewhat projecting, termen somewhat concave above, gradually rounded 
over more than lower half, dorsum considerably curved. Ochreous-lilac, 
strigulated and dotted with ferruginous which colour is edged with 
ochreous. Basal patch narrow, edge vertical, indent in middle, formed by 
much raised, rough scales, which give rise to the above mentioned costal

brushes deep ferruginous-brown anteriorly, light ochreous posteriorly; an 
ungulate ferruginous patch between brushes in disc; costal patch moderate, 
erect, oblique-serniovate or rounded-triangular, occupying slightly less

grey-lilac dot, edged with ochreous on costal margin ; median part of wing

confluent and continuous in disc, edged with ochreous, ground colour 
more or less suffused with dark lilac-grey; posterior edge of ferruginous 
colouring rather well-defined, indicating hind margin of central fascia, 
running from middle of costa to dorsum just before tornus, with an 
angulation in middle almost touching top of costal patch ; dorsum with an 
even dark lilac-greyish suffusion, dorsal edges dotted with dark fer- 
ruginous; terminal fifth of wing lighter, less densely dotted with fer- 
ruginous, which colour is broader edged with ochreous ; a moderate curved 
vertical or somewhat oblique blotch, narrow at extremities, from posterior 
edge of costal patch to tornus, sometimes more vertical and rounded 
above; a moderate and a small deep ferruginous costal dots before apex, 
first dot with a short projection below, second dot continued by a narrow 
ferruginous, ochreous-edged marginal striga in apex, and along termen to 
its middle. Cilia deep orange-fulvous, along apical half and below apex
