beneath : prothorax nearly linear, not broader than long ; meso- 

 thorax and metathorax with some testaceous marks in the disks of 

 the segments and with testaceous hind borders: abdomen much 

 shorter than the wings ; segments mostly with testaceous spots and 

 hind borders : legs testaceous ; tibiae with black tips ; tarsi white, 

 with a black band and black tips : wings hyaline, long and narrow, 

 slightly pointed ; stigma white, with a small adjoining brown spot 

 in the fore-wing ; veins white with black bands, ciliated ; subcostal 

 areolets simple, most frequently with a few of their veins towards 

 the stigma forked ; gradate veinlets towards the tip, and marginal 

 veinlets along the tip and along the hind border clouded with brown ; 

 a darker brown oblique streak on some veinlets in the disk beneath 

 the stigma, and another rising obliquely outward from the tip of the 

 fork of the cubitus, which is sometimes clouded with brown at its 

 base: hind-wings narrower but not shorter than the fore-win gs ; 

 forks of marginal veinlets towards the tips slightly clouded with
