Foreicing, vein 12 somewhat abruptly Lent upwards at its termination and ends 

 on costa some distance before the upper end of the cell, 8 from close to upper end of 

 cell, anastomosing with vein 7 for a short distance from its base ; discocellulars in an 

 even outward curve, the lower a little the longer, vein 3 emitted one-sixth before 

 lower end of cell, 2 from al)out one-third from the base. Costa gently and evenly 

 arched, ape.\- acute, truncate, the wing being somewhat angled at the end of vein 4, 

 the margin l)etween the angle and the apex evenly concave, from vein 4 to the hinder 

 angle the margin is very oblique and slightly sinuate. The outer and hinder margins 

 sub-equal, the latter nearly straight, nindwinj with the discocellulars faint, the 

 lowei- the longer, vein 3 emitted immediately before the lower end of coll, 2 from one- 

 fnurth liefore the end. Costa highly arched near its base, outer margin sharply angled 

 at the ends of veins 7 and 4, the margin excavated Itetween the two angles, making 

 the lower angle well produced and from thence to the anal angle nearly straight. 

 Antennfe more than half as long as the costa of forewing, club moderate, longer than 

 in Odontoptilum, gradually tbickening, recurved and sharply pointed ; palpi porrect, 

 third joint robust, bluntly pointed and very conspicuous ; hind tiliise with two pairs of 

 spurs, the upper pair minute, the male with a long tuft of hairs attached to the 

 proximal end of the hind tibiae.
