498 Ml{. W. F. KlJilir ON THJi GENERIC NOMENCLATUKE 



This admirable system is entirely ignored by all tlie French 

 authors ; but it doubtless ought to form the basis of our nomen- 

 clature, in spite of its rejection by Latreille. I will now consider 

 ychrank's genera in detail, on account of their importance. 



G-enus Erynnis. — Contains the following species — Malvarum, 

 MalvcB, Tages, Comma, JDinea, and Speculum. Staudiuger, with- 

 out apparent reason, retains the. name for Tages. It is doubtful, 

 however, whether it might not be better to retain it for Mal- 

 varum, as Spilothyrus is a name in less general use than Niso- 

 niades, and could not be retained in any case, being a synonym of 

 CarcJiarodus of Hiibner, a name of still less common use. 



G-enus Piebts. — This name may be retained as in ordinary 

 use, unless it should be rejected in favour of Danaus, which is not 

 desirable. 



Genus Maniola. — The subsequent genera SipparcMa, Sa- 

 fi/rus, and JErelia, are all synonymous with Schrank's first section 

 of Maniola. Meigen, almost the only author since Schrank who 

 has employed this name, detaches from the genus Schrank's 

 second section (Apatura), and the first species of his first sec- 

 tion (Galathea). But the characters Schrank gives of his fii'st 

 section of Maniola seem to agree best with Erelia of modern 

 authors ; and I am not aware that the genus to which Boisduval 

 has restricted the name of Erehia, Dalm., has any very strong 

 claims to be considered typical. I believe Dalman indicated 

 Ligea as his type; but his genus, being in efi'ect synonymous 

 with three of earlier date, can have no very strong claim to be 

 retained. 



Genus Papilio. — Schrank uses this name for all the Nympha- 

 linse, except Apatura; but as the name, as now employed, takes 

 in nearly the whole of the Equites of Linnseus, his application 

 of it might reasonably be disputed, even if no serious reasons 

 existed against its being applied to some typical genus of Nym- 

 plialince. 



Genus Cupido. — Least confusion would be created by adopting 



* These names are used as being less likely to confuse than, generic names, 

 whose correct application will he di.scussed in the sequel.
