Imago. — Wings subtriangular, broad, rather short. Underside of hindwings with 

 the subcostal median and submediau vein thickened and densely clothed with laxly 

 raised modified scales. Foretving with the costa much arched at the base and end, the 

 apex projected and acutely angulated, the exterior margin very slightly sinuated below 

 the apex, posterior angle rounded, cell long and broad, extending to beyond lialf the 

 wing ; costal vein ending at half the margin ; first subcostal branch emitted at fully 

 one-third and second at one-sixth before end of the cell, fourth at one-third before 

 lower end of the third, the fourth terminating before the apex, the fifth (or upper 

 radial) at some distance from beyond the cell ; discocellular bent deeply inward at 

 its middle, the radial from its upper angle ; median branches wide aparb ; submedian 

 much curved from the base. Hindwing broad, base of costa broadly lobate, apex 

 rounded, exterior margin very slightly sinuated hindward, its angle at end of the
