1872. Crotch, Cist. Ent. i. 66: says Silenus (Alcides) is type, through 

 "West wood, 1852. 



But it was determined long before that; for Helius was taken in 

 1816 as t3pe of lolaus, and nothing but Silenus then remained. See 

 also Loxura. 



719. Myscelia.* 



1844. [Boisd. ill] Doubh, List Br. Mus. 88 : Orsis, Numilia (My- 



calia), Acontius (Medea). 

 1849, Boisd. in ib., Gen. Diurn. Lep. 220 : employs it for Orsis, 



Cyaniris, Ethusa, and Antholia. 

 1861. Feld., Neues Lep. 16: L Orsis; II. Ethusa, Cyaniris. 

 1870. Boisd., Lep. Guat. 40 : claims it as his own, and says it was 



founded on the females of Epicalia, and so should be 



dropped. 



The name, too, is unfortunately near Miselia (Ochs., Lep. 1816), and 

 is actually preoccupied through Myscelus (Iliibn., Lep. 1816; Heyd., 

 Arachn., 1823). See Sagaritis. 



720. Myscelus. 



1816. Hiibn., Verz. 110: nobilis, Sebaldus, Erythus. 

 1852. Westw., Gen. Diurn. Lep. 526: the same and others. 

 1869. Herr.-Schaeff., Prodr. iii. 58 : u?es it for a large number 

 of species, including nobilis and Assaricus. 



1869. Butl., Cat. Fabr. Lep. 264: employs it for nobilis and 



Assaricus. 



1870. Butl., Ent. Monthl. Mag. vii. 92 : specifies nobilis as the 



type. . 



1871. Kirb., Syn. Cat. 587 : uses it in the same sense. 



721. Nahida. 



1871. Kirb., Syn. Cat. App. 651 : ccenoides. Sole species, and 

 therefore type. 

 Employed to replace Threnodes preoccupied. 



722. Nais.» 



1832-33. Swains., Zool. 111. ii. 136: Thyshe (splendens). Sole spe- 

 cies, and therefore type. 



Subsequently used by Felder. But one of the synonymes of 

 Thysbe is Nais, and the name therefore falls ; it is also preoccupied 

 in Worms (Mull. 1771).
