The only example being a ?, its generic place must remain doubtful; it is 

 probably related to L. mitranaria Wlk.

Pisoraca bitactcUa Wlk., xxiv., p. 1079, is manife.stly identical with Guent5e's 

 Ephyra lyciscaria Guen., Phal., i., p. 406. The hind tibiae of the c? of this insect 

 are armed with the three spurs characteristic of Hampson's genus Trirachopoda. and 

 this generic name must consequentlv give place to the earlier Pisoraca^ of Walker.
