276 THE ENTOMOLOGIST. 
Platyptilia marmarodactyla, Dyar (of which the authors kindly 
sent me six specimens), is a synonym of fuscicornis, Zell., 
common in South America and the Hawaiian Islands. I note 
also that one of Walsingham’s figures of cosmodactyla (‘ Ptero- 
phoride of California and Oregon,’ pl. il, fig. 4) is certainly this 
species, the different position of the scale-tooth of hindwings. 
and other characters being accurately given. 2 
Pterophorus (Oidematophorus) linus, Barnes, is a synonym of 
Lienigianus, Zell., ranging through Europe, Southern Asia, 
Africa, and South America. 
I take the opportunity to add my decided opinion that shaste, 
Wals., and fragilis, Wals., are synonyms of Platyptilia albida, 
Wals. (examples were also sent me) ; the authors, whilst keeping 
them separate: with hesitation, produce no distinctions that I 
should consider of specific value, and admit that apparently all 
three forms occurred in a long series from the same locality ; we 
do not find in nature three distinct but indistinguishable species 
occurring together.

NOTES ON THE SYNONYMY OF DIONE MONETA, 
HUBN. AND OIG iYC Hin AS ann: 
By Artuur Haut, F.E.S. 
Dione moneta was first figured by Hubner (1820-26), his type 
being probably from South Brazil. The species occurs in three 
slightly but distinctly different subspecies, two of which are very 
common in collections, whilst the third, which happens to be the 
typical one, is rather rare, and this fact has caused considerable 
confusion in its synonymy. 
Doubleday and Hewitson (1848) gave a figure which seems 
to represent the Central American race. 
Butler (1873), having apparently never seen typical moneta, 
thought that Hubner’s figure was intended to represent the species 
afterwards described by Felder as D. glycera, and so re-named 
moneta as D. poeyti. He united the Central American and 
Andean races under this name, but as he specifically refers to. 
Doubleday’s figure, the name poeyiti may stand for the Central 
American race. 
Salvin and Godman (1882) correctly identified the species, 
although evidently a little puzzled by the absence of typical 
specimens, as they suggest that Hubner’s figure is bad, whereas. 
it is in fact very good. ‘They also unite the Central American 
and Andean races under the name of moneta, and treat poeywt as 
a synonym. 
Stichel (1907) correctly separates the species into three races, 
giving the name butleri to the form occurring in Venezuela,
