 inner angh' is ehnigated into a Munt, rounded, aborted tail, making the wing 

 as broad near the l)a.se as near theape.x, and beyond the "tail'' the inner edge 

 is exactly parallel to the costal. The onter edge is short and straight, less 

 obli(|UC than in the narrow-winged species of' Achhilia. The hind wings are 

 still more grofesfpic than the primaries, a}»pearing as it' crumpled up f'l'om not 

 having properly exiiandcd alter the moth had left the pupa. They arc so 

 deeply notched in the inner part of the outer edge (jf the wing as U) appear 

 hil'Lircate, sending the iniu'r i'ork, which is acute, nearly as far as the tij) of 

 the abdomen, while the outer hall' oC the wing forms the other fork. The 

 inner edge of thi' wing is mmdi revolnte, and near the l)ase of the inner fork 

 carries a crest of line inrolled hairs. The venation is \cvy remarkable. 

 ^J'heri^ is a subcostal cell and but three sulx'osfal veins, the main vein branch- 

 ing but three tinu's; the usual two suhapical veins wanting. The iiidepend- 

 <'ui vein is thrown oil' t'rom the base of the anterior discal veins. The third 

 median vein is very slnn-f, and its origin is very remote from tiie first two.
