Plusia V. argenteum (Esper) = Mya (Hubner). Fore- 
wings olive, with red-brown pattern surrounding the 
orbicular and reniform stigmata in a somewhat triangular 
fashion, the lower edge of the orbicular stigma, an angular 
mark, and some other dots silvery. A very rare moth, 
inhabiting the Valais, near Zermatt. Larva feeds on 
Isopyrurn thalictroides, a Eanunculaceous plant. 
Cucullia argentina (Fabr.), one of the Shark Moths, of 
which there are several species in this country, has pale 
olive forewings, with a very broad longitudinal silvery 
mark ; it much resembles an enlarged Crambus margaritellus, 
as Mr. Kirby has aptly remarked in his work on European 
Moths, and is a native of the Altai Mountains and south 
Russia. 
Oxytripia orliculosa (Staudinger), allied to Valeria 
oleagina, a reputed British species, is a native of Hungary, 
but very rarely found. It is brownish grey, with large white 
round blotch in the middle of each forewing; hindwings 
white, edged with sandy grey. 
Xanthodes Groellsii (Feisthamel). Forewings yellow, 
with a broad red longitudinal stripe diagonally across each 
wing — fringes dark silvery grey. Larva feeds on Lavatera, 
and the insect is an inhabitant of Spain, and has a wide 
range also in the East Indies, as far as Mauritius. There 
are several species of this genus, which is allied to Chariclea, 
in the Himalayas, and one other (X. Malvse) in S. Europe, 
which is also a very beautiful species. 
Mr. Thomas Rogers exhibited a number of varieties of
