Overlooked the fact, that this species is the type of 

 Eheiimaptera, Hiibner, 1806 (1811), and that this is the 

 earliest generic term applied to any member of the present 

 group. The initial fact, with which any study of this series 

 must commence, is expressed by this name. Beyond Rheuiiia- 

 2)tera for hastata, no generic title seems here to be quite 

 assured. Conceding Mr. Meyrick's species to be correctly 

 associated, his genus, Plemijria, must give way to Eheumaptera, 

 with hastata as type. But there are further objections to 

 Plemyria. It is twice used in the Verzeichniss ; the second 

 time iox fiuviata [gemmata), for which species it not only falls 

 as a synonym, but the species itself is taken by Ochyria. The 

 first time it is used (p. 327) by Hiibner for rubiginata, 

 fliictuata, procellata, stragidata. Not one of these names 

 occurs in Mr. Meyrick's list of species. Even if a specific 

 title there cited covers one of Hiibner' s original species of 

 Plemyria, the fact should have been mentioned, to avoid the 

 appearance of using a generic name for different species from 

 any of those for which it was originally proposed. 



" Eustroma, Meyrick, I. c, 71. No mention is made by Mr. 

 Meyrick of the fact, apparent both from his diagnosis and the 

 list of species given by him, that this is equivalent to Li/gris of 

 Lederer, 1852 ; the type of which is pojndata. For this structural 

 type the term Petwphora, Hiibner, 1806 (1811), is incorrectly 

 used by Dr. Packard, since the type of this name is maeniata. 

 Consequently Petrophora must be used instead of OrtJiolitha, 

 Hiibner, which falls as a synonym. The trinomial use of 

 Petrophora, in the Sammlung, is not of authority, since our 

 nomenclature is binomial. And now as to Emtroma. It is 

 proposed in the Verzeichniss, 335, for siifnwata, prunata, 

 silaceata, and reticulata. It contains thus two species in- 

 cluded by Lederer in his genus Lyyris, and Mr. Meyrick's 

 course virtually amounts to this, that he supplants Lyyris, 

 with its type populata, by Eustroma, with the type reticu- 

 lata or prunata. The genus Lyyris is proposed by Hiibner 

 on the same page, and immediately following, for pyro]>ata 

 achatinata, populata, and pyraliata. The genus Lyyris, of 

 Lederer, defined by the character of a hair pencil on the fore- 

 wings of the male primary beneath, contains as European
