Rufous-brown ; front shining ; palpi brownish ; vertex slightly 

 carinated ; antennae yellowish, the two basal joints darker brown- 

 ish, the other sometimes darker annulated ; thorax brown ; legs 

 yellow, the four anterior tibiae with two indistinct blackish bands, 

 extreme tip of tarsi darker ; front wings about half as 'broad as 

 long ; apex elliptical ; slightly pubescent, luteous-hyaline, faintly 

 mottled with brown spots ; crossed with three oblique about equi- 

 distant very narrow brown fasciae, which are intersected by three 

 similar longitudinal fasciae ; the venation is luteous, interrupted 

 with fuscous ; along the margin are dark fuscous forks and spots ; 

 four to five sectors ; seven veins in the apical gradate series ; six 

 in the inner one ; hind wings pale, more hyaline, some darker 

 blackish veins along the front and apical margin. Abdomen dark 

 brown ; male with a yellow spoon-shaped ventral valve ; the last 

 dorsal segment paler, truncate, split from below two-thirds of its 

 length: out of the split two processes reach more or less, viewed 

 from the side straight, from above with the apex bent inside ; 

 this apex is black, sharp, the convex part cut horizontally ; both 

 processes together represent a kind of forceps, in which the bent- 

 up apex of the penis is placed ; the penis is long and narrow, 

 gradually enlarged to base, tip split below (or bifid?) two longer 

 divergent straight spines above the lower valve, originating near 

 the base of penis. Female with the end of abdomen blunt, pale.
