Additions to the Catalogue of U. S. LEPIDOPTERA. 

 BY AUG. R. GROTE. 



Under this title I propose to describe such species of U. S. Lepidoptera 

 which may be found to be unenumerated in the " Catalogue of the describ- 

 ed Lepidoptera of North America" published by the Smithsonian Insti- 

 tution; with reference also to subsequent publications.. 



In case any of my species should prove to be synonyms, I will cheerfully 

 acknowledge them as such and give the priority to the rightful author. 



My thanks are due here to Mr. E. Richard Straznicky of the Aster Li- 

 brary N. Y. for his kind attentions. 



NOCTU^. 



Gen. CHERSOTIS Boisd. 



C. plecta Linn. United States and Europe. 



Anterior wings dark brown, silky, with a broad grayish band on the up- 

 per margin, extending from the base about three-quarters of the entire 

 length of the wing. At the base a deep black streak, and a second one 

 running as far as the outer grayish band, encloses two grayish spots of 

 which the outer one is bean-shaped and the inner spherical. Posterior 

 wings white; fringes light. Head, tegulae and body grayish; thorax dark 

 brown. Exp. li inch. 



Ohs. This species, which is not uncommon in the vicinity of New 

 York, I find on comparison to be identical with the European C. plecta. 

 The position for this genus in the Catalogue is immediately after Nochm. 



Gen. DYPTEEYGIA Steph. 



D. pinastri Linn. United States and Europe. 



Anterior wings brownish-black with two irregular black transverse lines
