Tyrone (local among birches at Cookstown), Monaghan, Fermanagh (Enniskillen), and Galway.
Dotted Border (Hybernia marginaria).
On Plate [120] four specimens of this rather variable species are depicted. Figs. 8 ♂ and 10 ♀ show the more usual form; Fig. 12 represents the northern English, blackish var. fuscata, Harrison, and Fig. 11 an intermediate form resulting from a cross-pairing of fuscata ♀ with a southern ♂. Somewhat similar forms to the last have been captured in Wear Dale, Durham.

The caterpillar is figured on Plate [125], from a coloured drawing by Mr. A. Sich. It is described by Fenn as dull yellow, olive green, or greenish brown; a series of dark grey X-like marks on the back, most distinct on rings 5-11; the spiracles are white, each placed in a black cloud, and the spaces between them paler, sometimes yellowish; the last ring is often brown without marking, and the front rings have a purplish stripe above; under surface, paler throughout. It feeds, in April and May, as a rule, but has been found later, on hawthorn, sloe, oak, birch, alder, sallow, etc., and may be obtained in the daytime.
