Wings fuscous violaceous, the apex of the costal cellule, the 2 radials, the apex 
of the 2nd cubital and the apical margin of the wings darker coloured, almost 
black, the nervures black, the apex of the radius is broadly, ronndly curved 
and projects more than the length of the apical transverse cubital beyond the 
latter, which is roundly curved outwardly in the middle. The pubescence is 
long and dense, blackish on the scape of antenne, the front, vertex, mesono- 
tum and abdomen black, on the other part and legs grey, almost white, that on 
the basal ventral segments being also pale ; that on the metanotum is much 
longer and denser than it is on the mesonotum. Female.
