obsolete, sometimes indicated by a sliglitly darker shade in s. t. space, 

 which then forms a faint contrast in color to the concolorous terminal 

 space. Ordinary spots moderate, concolorons, never complete, marked 

 only by the otherwise blackish cell. Secondaries smoky fuscous, paler 

 toward base ; a distinct discal luuiile. Beneath pale, powdery, with an 

 ochreous or reddish snttnsion, a common dusky shade line and distinct 

 discal lunule. Thorax concolorous, front blackish brown. 



Expands 35™'" ; 1.40 inches. 



Habitat. — New York and northward. 



Very distinct from the other dnsky fronted species by the broader 

 wings, the rectangular apices and the blackish cell. The very distinctly 

 crenate t. p. line adds a characteristic appearance to the species.

The only specimen known to me is a 9 marked "Type" by Mr.

Geuus CHORIZAGROTIS Suiitb. 



Anterior tibnie spinose, moderately well armed at tip. Front moder- 

 ate, produced into an acute or cylindrical tubercle. Antenna of S sim- 

 ple, ciliate. Thorax depressed, untufted, or with an indefinite basal tuft 

 only. Abdomen depressed, somewhat flattened 5 in terrealis onty, nor- 

 mal. The primaries are elongate, rather narrow, subequal, the apices 

 Bomewhat rounded. Terrealis here also is an exception, the primaries
