 at two-fifths ; submediau and internal vein straight. Body moderately stout ; frontal 

 tuft prominent; palpi ascending, second joint reaching vertex, compressed, laxly 

 squamose, third joint linear, acute at the tip, about two-thirds length of second ; 

 antennae in male rather thick to nearly three-fourths its length, where the shaft is 

 slightly dilated and dislocated, the end slender, with both short and long setfB to the

 the apex to posterior margin, the line being angulated inward between the median 

 and submedian veins and there broadly dilated with black, the outer border of the 

 line being clouded with brown; above the posterior angle are two black-speckled 

 spots, and along the margin is a row of black points ; two or three blackish- speckled

 margin oblique, very slightly convex ; cell extending to half the length ; first 

 subcostal emitted at nearly half before end of the cell, second close to the end, 

 trifid, third at one-half from base of second, and fourth at one-half from base of 

 third, fifth from end of the cell and slightly touching second at half-way between its 

 base and third ; discocellular concave in middle, bent close to each end, radials from 

 the angles ; middle median at one-seventh before end of the cell, lower at three- 

 sevenths ; submedian slightly recurved : hindwing rather long and triangular, exterior 

 margin very oblique ; discocellular very slender, inwardly oblique, radial from near 

 lower end ; two subcostals from end of the cell ; two upper medians on a footstalk
