Erioptera (Empeda) noctivagans Alex. (Alexander, 1917:200-201), 

 from Virginia, has been described since the completion of the above key. 

 It is closest to E. stigmatica, but is larger and darker, the wing veins are 

 dark brown with an indistinct darker seam along the cord, and the three 

 pleural appendages of the male hypopygium are very unequal in length, 

 the shortest being less than two-thirds the length of the longest and 

 conspicuously bifid at its apex. The very long verticils of the antennae 

 in the subgenus Empeda are present, but are less conspicuous than in 

 E. stigmatica.
