24. Dark median band complete and sharply defined, outwardly biangulate, well 



separated from subtornal spot (21) nordeggana. 



Dark median band usually mottled and broken by pale patches, poorly de- 

 fined, and very irregular in outline ; when complete and defined, fused 

 with subtornal spot (in species having a mottled and broken median 

 band the subtornal spot is frequently well separated from the remains of 

 dark median band) 25. 



25. Fore wing a suffused mottling of ashy gray and blackish fuscous with no 



well-defined whitish areas except a white dot at end of cell, and with 

 none of the usual dark pattern markings distinctly defined. 



(23) intermistana. 



Fore wing more or less mottled ; but always with one or more definite 



whitish areas beside the occasional white dot at end of cell, and with one 



or more of the usual dark pattern markings distinctly defined 26. 



26. Subtornal dark spot of fore wing distinctly separated from dark median 



band and more or less extended 27. 



Subtornal dark spot fused with median band 29. 



27. Fore wing with a well-definetl subapical bar touching at its discal extremity 



the apex of subtornal spot (22) schulziana. 



Fore wing without subapical bar, or latter represented only by a small dark 

 spot on termen above tornus 28. 



28. Fore wing wider toward termen than at middle (25) inquietana. 



Fore wing no wider toward tennen than at middle (26) bowmanana. 



29. Postmedian whitish area of fore wing most extendetl toward costa. 



(27) mengelana. 

 Postmedian whitish area most extended toward tornus (30) buckellana.

In this spicies vein 2 of fore wing branches from the cell very 

 close to outer three-fourths, further out in fact than it does in any 

 other species in the genus. However, there doesn't seem to be any 

 good reason for generic separation. 



Male genitalia figured from specimen in National Collection from 

 Hampton, N. H. (S. A. Shaw, " VIII-14-1907") ; female from 

 specimen in American Museum from Cincinnati, Ohio (A. F. 

 Braun).
