 length of costa : male with a costal fold; vein 12 reaching costa 

 well before the end of cell ; discocellulars suberect ; vein 5 nearer 

 to 6 than to 4 ; vein 3 shortly before end of cell, more than twice 

 as far from 2 as from 4 ; vein 3 more than twice as far from end of 

 cell as from base of wing. Hind wing : outer margin crenulated ; 

 vein 7 well before the end of cell ; discocellulars and vein .5 barely 

 traceable ; vein 3 shortly before eud of cell ; vein 2 only slightly 

 nearer to eud of cell than to base of wing. Hind tibiae slightly 

 fringed and with two pairs of spurs.

Nearest to Lignyostola, Mab., with which it agrees in neuration, 

 except that the veinlet in the cell terminates only just beyond vein 3, 

 and that vein 2 of the fore wing is considerably nearer to the base 

 of the wing. The antennae are longer and have the club more bent 

 round. The palpi are similar. The hind wing is cpiite a different 

 shape, being much ])roduced in the submedian area, wliile in Ligmj- 

 ostola it is much produced in the subcostal area. The anal lobe is 

 also comparatively inconspicuous, the outer margin not being excised 

 just before it.
