AcTiAS Leach. Logotype PhaJaena hina Linn. 



1815. Leach, ZooL Misc., II, 25; liina and selene. 



1874. Grote, Proc. Am. PhiL Soc. XIV, 257, cites luna as type. 



1892. Kirby, Cat. Lep. Het. I, 766, cites selene as type. 



1912. Packard, Men. Bomb. Moths N. A. Ill, 181, uses for selene. 



Tropaea Hbn. Logotype Echidna caudata selene Hbn. 



1820. Huebner, Verz. bek. Schmett. 152; hina, selene. 



1864. Packard, Proc. Ent. Soc. PhiL III, 379, uses for luna, but cites no 



type. 

 1892. Kirby, Cat. Lep. Het. I. 765, separates from Actias, but cites no type. 



Plectropteron Hutt. Haplotype Echidna caudata selene Hbn. 



1864. Hutton, Ann. & Mag. Nat. Hist. XVII, 60; diance (syn. of selene) sole 

 species and therefore type. 



These three genera offer a nice problem in type fixation. When 

 selene became type of Plectropteron in 1846, the types of one or both of 

 the other two genera were automatically fixed as luna. A possible 

 solution is that luna became the type of Actias, since that genus takes 

 priority over Tropcea, and that either species could then be selected as 

 type of Tropcea. Since Grote later cited luna as the type of Actias, 

 everything favors this fixation. If it be thought desirable to separate 

 selene and luna generically, the selection of a type for Tropcea becomes 

 of some importance. We have been unable to find any type specified, 

 so we designate selene in order that the earlier names may stand. 

 Hampson, Rothschild and other writers regard selene and luna as 

 congeneric, in which we follow them. 



CER.A.TOCAMPID.^. 

 Eacles Hbn. Logotype Attacus imperialis Dru. 



1820. Huebner, Verz. bek. Schmett. 153; imperatoria and others. 

 1874. Grote, Proc. Am. PhiL Soc. XIV, 260, cites imperialis {imperatoria) as 

 type. 



We are unable to find any previous type fixation, and the name is 

 not preoccupied, hence there appears to be no reason why it should not 

 apply to the species now listed in Basilona. We are unable to find any 

 designation of a type for the latter genus, and take this opportunity 

 to suggest cacicus, which is congeneric with imperialis, as also is the 

 remaining species, ducalis, according to Packard. 



SYNTOMID^. 



PsEUDOMYA Hbn. Logotype Glaiicopis tipulina Hbn. 



1820. Huebner, Verz. bek. Schmett. 124; melanthus, tipulina, temenus, eacus. 



1892. Kirby, Cat. Lep. Het. I. 138, cites tipulina as type. 



1898. Hampson, Cat. Lep. Phal. B. M. I, 262, cites melanthus as type. 



Owing to Kirby 's designation of tipulina, this genus will replace 

 Saurita in Hampson's Catalogue, and is not represented in our fauna. 

 Its place is taken by 



PsEUDOCHARis Druce. Orthotype P. naenia Druce. 



1884. Druce, BioL Cent. Am., Lep. Het. I, 56, P. naenia designated type.
