Noctuidae 



in recent years been ranged under the name Carneades after the 

 teaching of Grote, but as Carneades, which was erected by 

 Bates, includes a different concept, this name was abandoned 

 by Dr. Dyar, and the name Paragrotis Pratt was substituted for

 by Hiibner, and which we have adopted at the suggestion of 

 Prof. J. B. Smith.
