Aberration of var. valesina.
The butterfly is probably to be found in most of the Southern English and Welsh counties, especially where there are extensive woods. In North Devon, however, it occurs in places where there is not much in the way of woodland. It is abundant in the New Forest, and also in some parts of Ireland. Although it has been observed as far north as the Clyde, it is scarce in North England and Scotland. The valesina form is to be seen, in July and August, in the New Forest every year, and sometimes in numbers. This variety has been reported from Kent, Sussex, Devon, and Dorset; also from "near Reading" and "the border of Hertfordshire."
