662. MEGAMEDE. 



1816. Hiibn., Verz. 50: Rhetenor (Rhetenoris, Chalciope). Sole 

 species, and therefore type. 



663. MEGASTES.* 



1851. Boisd. in Westw., Gen. Diurn. Lep. 346: given as a MS. 



synonyme of Dynastor (q. v.) by Westwood. 

 The species of Dynastor were Napoleon and Darius. Megastes, 

 however, was only applied to Napoleon (Napoleo), and hence the name 

 must fall before Dynastor. 

 1870. Boisd., Lep. Guat. 53 : Macrosiris, Darius. 



664. MEGATHYMUS.* 

 1872. Scudd., Syst. Rev. 62 : yuccce. Sole species and designated 



type. 

 It is not a butterfly. 



665. MEGISTANIS. 



1844. [Boisd. in] Doubl., List Br. Mus. 109 : Acheronta (Cadmus), 

 Baeotus (Beotus). 



1849. Boisd. in Doubl., Gen. Diurn. Lep., pi. 48: Boeotus (Beotus). 



1850. Ib. in Westw., Gen. Diurn. Lep. 311: Baeotus (Beotus), 



Acheronta (Cadmus), and another. 



By the publication of the plates of Doubleday and Westwood's Gen- 

 era, Baeotus became the type, and in this sense it has been employed 

 by Felder and Kirby. But Boisduval in 1870 (Le'p. Guat.) refers 

 Acheronta again to it. Kirby in his Synonymical Catalogue refers 

 the genus to Westwood. 



666. MEGISTO. 



1816. Hiibn., Verz. 54: Euritus (Cymelia), Argante, Canthus 

 (Euridice), Acmenis. 



1868. Butl., Cat. Sat. 14 : specifies Eurytus as the type. 



1872. Scudd., Syst. Rev. 6 : does the same. But Eurytus is strictly 

 congeneric with Penelope, the type of Cissia, and there- 

 fore Acmenis may be taken as the type of Megisto. 



667. MEGONOSTOMA.* 



1863. Reak., Proc. Ent. Soc. Phil. ii. 356: Cesonia (Ccesonia), 



Eurydice, Philippa, Helena. 



1870. Butl., Cist. Ent. i. 36, 46 : specifies Cesonia as the type. 

 1872. Kirb., Syn. Cat. 489 [Meganostoma] : Cesonia and allies. 



The name must fall before Zerene, which, by the foundation of 

 Eurymus, became restricted to this group.
