44 MR. A. G. BUTLER ON A NEW GENUS OF LEPIDOPTERA. [{Jan. 14, 
the national collection testifies to the contrary. This individual was 
obtained in the year 1841; and on turning to the old Register I find 
it entered as Erycina charmione (ex Mus. Milne), and in pencil a 
note—‘‘ Not a Rhopalocére at all!’ No locality is given. It is not 
impossible that this is actually the type specimen formerly existing 
in the collection of Mr. Drury ; for it seems certain that at least one 
species formerly in that collection, and pinned in the same manner, 
now exists in the British Museum*. 
Mr. F. Walker has kindly referred me to the genus Nyctemera, 
Hibn., which he considered the nearest approach to the charmione 
type of coloration and general form ; and amongst the species of that 
group I detected one (NV. expandens, Walker) agreeing with the 
latter in every structural particular, and differing from the remaining 
species in its narrow elongated wings and different neuration. These 
two species will therefore form a new genus allied to Nyctemera.
