tions, the name of our l)liie 1 )iittertlies. They were comprised 

 by Liiuucus in the suh-genns Flebeius and P. argiis was 

 selected hy Cuvier as the typical species in 1799 ; the 

 same, (jrovj) was variously styled Cupido {Schrank, 1801), 

 Polyonnnatus {Latr., 1805), Lyctena (Fahr., 1807), Zephyms 

 (Balm., 1816); all four of which names are therefore co- 

 extensive (though n(jt co-typical), and if revived, which 

 appears to me undesirable, they nuist he quoted from some 

 later author. 



1735. Linnteus (Syst. Nat. YA. i.) grouped all our Lepidop- 

 tera in the genus Pajnlio (ty]t. P. Machaon, Cur. 

 1799). 



1748. Limifeus (Syst. Nat. ed. vi.) separated tlie nocturnal 

 species under the title l*h(davim. 



1758. Linnteus (Syst. Nat. ed. x.) separated the crepuscular 

 species under the title Sphinx. He also sub- 

 divided his genus ra'pilio into six sub-genera, 

 whose names have been accepted, and, as I con- 

 ceive rightly ; for Linnteus always used them 

 sub-generically, speaking of Papilio Danane Bras- 

 sica\ These are — 



A. Equites. This has been always (except by 

 Geoffroy and Schrank) considered the typical 

 stirps. 



B. Hcliconius, type H. Psidii, Lam. (1801). 

 c. Banaus, type D. Brassiciie, Cva\ (1799). 



D. Nymphalis, type N. atalanta. Lam. (1801). 



E. Plebeius, type P. argus, Cuv. (1799). 



F. Bai'harus, a heterogeneous group which has 

 not since been accepted. 



The type of the genus Sp)hino:. is, according to La- 

 marck (1801), S. convohndi. Latreille (1805), 

 figured S. atrojws as its type, which was sepa- 

 rated by Ochsenheimer (1816). 



The genus Phalam.a is also sub-divided into seven 

 sub-genera : — 



A. Bomhyx. Cuvier (1799) and Lamarck (1801) 

 divide this into three sections, whose types are 

 B. 2M'vonia, B. dispar, and B. mori ; Sclirank
