This is not an English species, but is met with in
Europe and North Africa. It is not very commonly found
in Teneriffe. The fore-wings are green, with a central
reddish-brown spot, the outer margin having an indented
band of the same colour. The body and hind-wings,
richly feathered, are a beautiful straw yellow, the latter
having a dark brown graduated band near the lower
margin. It expands about two inches and a half. The
larva is grey, with a pale grey stripe on the sides, and
black spots on the lower surface between the pro-legs.
