The caterpillar is pale green with a dark-green edged ochreous brown stripe along the middle of the back, and green stripes on each side; the usual dots are black, and the plates on first and last rings are brown, as also is the head. It feeds, in September, on the seeds of eyebright (_Euphrasia officinalis_). The moth is out in July and August, and is found very locally, flying in the late afternoon among its food plant, on the moorlands and pasture-grounds of Northumberland, Cumberland, Durham, and Westmorland; and has been reported from Hawkshead, in Lancashire. In Scotland, it is common in suitable parts of Roxburghshire and several localities in Clydesdale; thence widely spread to the Orkneys. Only noted from the Mourne Mountains in the north-east of Ireland, but probably to be found in other parts of that country. PRETTY PINION (_Perizoma blandiata_). This species (Plate 83, Figs. 7, 8) is also known as _adaequata_, Borkhausen, the name under which it is catalogued by Staudinger. As a rule the central band on the whitish fore wings is only represented by a round, or sometimes triangular, blackish spot on the front margin, a smaller blackish mark on the inner margin, and some dusky clouding between these two portions. In specimens from the Hebrides the band is more or less complete, and in some of them it is very much narrowed, especially towards the inner margin (ab. _coarctata_, Prout). The caterpillar is green, with three crimson lines, the outer ones bent inwards to the central one on the middle of each ring; two lines above and one below the yellowish spiracular line are pink; head green, tinged and freckled with pink. It {211} feeds in September on the flowers and seeds of the eyebright (_Euphrasia officinalis_). The moth is out from late May to July, and its habits are similar to those of the last species. In Scotland it appears to be commoner than in other parts of the British Isles, its range extending from Clydesdale to the Hebrides, Orkneys, and Shetland; but it has been recorded from Cumberland, and once from Durham. In Wales it has been taken at Dolgelly, in Merionethshire. Prout states that in 1902 he secured two specimens near Cwm Bychan, and that the species has since been captured regularly in the locality. It is widely distributed throughout Kerry and Galway, and also recorded from Cork and Derry, in Ireland. THE BARRED CARPET (_Perizoma taeniata_). This species is shown on Plate 85, Fig. 3. There are two forms of the central band of the fore wings, which in the type as figured by Stephens is broad, but is narrow in ab. _arctaria_, Herrich-Schaeffer = _angustifasciata_, Staud. The colour of the bands may be greyer or browner than in the specimen figured, and the ochreous general colour of the fore wings is more tinged with brown in some specimens than in others.
