VII. Additions to the "List of North American 

 Noctuidae" 



liY AUG. II. GROTE. 



[Read before this Society July 3, 1874.] 



The discovery of new species since the publication ol" the "List," 

 and the reception of fresh material hy this Society, allows me to 

 increase and correct it. 



I. The genera allied to Taeniocamjja, catalogued on pages 22 and 

 23 of the " List:' 



The following synoptical table is imperfect, but may assist in the 

 identification of the genera. I have no perfectly preserved speci- 

 mens of Ceramica exusta, and the structural difference from Taenio- 

 campa is not apparent to me. Perfectly preserved specimens, with 

 the thoracic vestiture intact, are especially necessary in studying 

 the Noduae. I have hitherto mistaken the type of Pachnobia. 



Eyes hairy : 



Head prominent, vestiture liairy, form slender, tliorax untufted . . . Ortliodes. 



Head applied to the thorax, collar distinctly lobed, thorax defined at the sides 



and tufted in front Terigrapha. 



Head sunken, vestiture woolly, form stout, thorax untufted -j (Jeramica! 



Eyes naked : 



Male antennae simple, wings comparatively wide Matuta. 



Male antennae toothed, wings comparatively narrow Pachnobia. 



ORTHODES, Guenie (1852). 



Type : Orthodes infirma Ouen.
