BRYOPHILA ALGÆ (Fabr.).
This is a small moth, with the same characteristics as to size and form as the last described. The fore-wings are green, varied with brown and blackish in the position of the claviform stigma. It has dark transverse lines, and the hind-wings are brownish grey. The larva is bluish-grey, with a grey stripe on the back. It feeds on lichen, and inhabits Central and Southern Europe, and Western Asia, but is a great rarity in England.
