759. NYTHA. 



1820. Billb., Enum. Ins. 77: Hyperbius, Medea, Clytus, Msera, 



Agave (Alcyone, Hippolyte), Semele, Hermione, Briseis, 



Statilimus (Faunus), Fidia, and several MS. Species. 



All these species, excepting Hermione and Briseis, fall into the genera 



Erebia, Eumenis, Pararge, Melampias, and Dira ; all of which are of 



earlier date. The name may therefore be retained for these two species 



and their allies, with Hermione for type. See also Maniola and Oreus. 



760. OARISMA. 



1872. Scudd., Syst. Rev. 54: Poweshiek. Sole species and desig- 

 nated type. 



761. OCALIS* 



1851. Boisd. in Westw., Gen. Diurn. Lep. 371 : Westwood gives it 

 as a MS. synonyme of Oressinoma (q. v.). 



1870. Boisd., Lep. Guat. 63 : Typhla. Sole species, and therefore 



type. 



This name falls before Oressinoma; and is besides too close to 

 Ocalea (Erichs., Col. 1837). 



762. OCHLODES. 



1872. Scudd., Syst. Eev. 57 : nemorum, agricola, Sonora. Nemo- 

 rum specified as type. 



763. OCYTES. 



1872. Scudd., Syst. Rev. 55 : Metea, Seminole. Metea specified as 

 type. 



764. (ENEIS. 



1816. Hiibn., Verz. 58: Norna (Norna, Celaeno), Polixenes (Bore), 

 Jutta, Arethusa. 



1868. Bud., Ent. Monthl. Mag. iv. 196; Cat. Sat. 160: specifies 



Norna as the type. 



1871. Staud., Cat. 27 : uses it in the same sense. 



1871. Kirb., Syn. Cat. 68: the same. 



1872. Scudd., Syst. Rev. 4 : specifies Norna as type. 



See also Chionobas. 



765. CENOMAUS. 



1816. Hiibn., Verz. 76: Marsyas, Ortygnus, Eumolphus, Rustan, 

 Palegon. 



1869. Butl., Cat. Fabr. Lep. 196 : employs it for Marsyas. 



But this is already the type of Pseudolycasna. Ortygnus may be 

 chosen as the type.
