 whitish hairs on anterior and middle segments. Antennae 

 white, biciliated with tufts of pale yellow hairs ; at greatest 

 length one and a half, apex of antenna? simple. Forewings 

 elongate triangular ; costa straight, hindmargin obliquely

 with black at extremities of veins. Hindwings white, hairs 

 of inner-margin blackish, costal edge blackish ; cilia white, 

 partly chequered with black. One specimen at Broken Hill in
