scientious friend in Stephens, as early as 1825. ]\Ieanwhile the 

 text-books of his fatherland placed the letters " Tr." or " Ochs." after 

 such generic names as Agrotis, Erastria, Diplitliera, Graphij)hora, 

 Gortyna, A2)atela, Xanthia, CijmatopUora, Ileliotliis, designations 

 proposed by Hiibner when European entomologists were for the 

 most part far behind in any adequate comprehension of the classifi- 

 cation of the Sub-order. 



NOCTUAE Linn. (1788). 



* DEMAS Steph. (1829). 



Type : Bombyx coryli Linn. 

 t versicolor Morr., Proc. B. S. N. H., 1874, 133. Massachusetts. 



EUTOLYPE Grote (1874). 



Type : Eutolype Rolandi Grote. 



Kolandi Grote, Proc. Acad. Nat. Sci. Phil., 1874, 198 ; Copipanolia vernalis, 

 Morr., Proc. B. S. N. H., 133. Massachusetts ; Missouri. 

 [Note. — This genus may succeed Dicopis, in the " List."]

 * DIPHTHERA Hubyier (1806). 



Type : Diphthera Aprilinaf Hubn. (nee Linn.). 



fallax Herr.-Sch., Exot., S. 80, fig. 211. 



[Note. — Hubner's aprilina is not Linne's species, but the orion of Esper. In 

 1806 Hiibner gives his " aprilina" as the type of Diphthera, a name afterwards 

 appropriated by Ochsenheimer. Guenue's " Bombyciformes," 18o2, is an appro- 

 priation of Hubner's " Bombycoides," 1806, under another name. Tlie term 

 Diphthera must l)e restored to its original signification. For the European 

 Diphthera ludifica Lederer ex Linn., I propose the term Tricliosea and restrict 

 Moma to the species Moma Astur Hiibn. ex Cram.] 



*APATELA Hiibner (1806). 



Type : Noctua Aceris Linn. 



[Note. — This is Hiibner's type in the Tentameu. I would refer all the forty- 

 seven species, cited by me on pages 7 and 8 of the " List " under Acronycta, 

 to Apatela ; for the sake of brevity I omit here their separate designation. 

 In case of a disintegration of the genus, Acronycta must be retained with its 

 tj'pe leporina, as cited by me in the " List," and as restricted by Hiibner in 

 1816, for certain of the species. I cite here the North American species of 

 Apatela, which are not included in the " List " under Acronycta.^
