The fore wings of this moth (Plate [106], Fig. 12) are pale greyish brown, purplish brown, or sometimes slaty brown, with fairly distinct black cross lines, and a pale streak along the front edge; the first line is straight and less angled, and the second line less curved towards the front margin than in A. tritici. The caterpillar, which feeds from about October to July on rock rose, bedstraw, and other low plants growing in rocky places by the sea or on hillsides, is very similar to that of the last species. The moth is out in August and September in its special haunts. A well-known locality for it is Freshwater in the Isle of Wight, but it may be obtained at Torquay, Devonshire; Padstow, Cornwall; and the Scilly Isles. Also recorded from Sussex, Gloucestershire, Herefordshire, South Wales, Derbyshire, Cheshire, Lancashire, and Yorkshire. In Scotland on the south-west and east coasts; and in Ireland at Howth, Dublin; Dungarvan, Co. Waterford; and Mt. Charles, Donegal.

The Heart and Dart (Agrotis (Feltia) exclamationis).

On Plate [105] are figured two examples of the male (Figs. 3, 4) and two female specimens (Figs. 5, 6). The colour of the fore wings ranges from pale whitish brown through various shades of brown and grey to a sooty brown or black. The cross lines are rarely very distinct, the reniform, orbicular, and claviform marks are, however, generally much in evidence; but either of the two last, sometimes both, may occasionally disappear. Not infrequently the reniform is connected with the orbicular by a black streak from the former; more rarely the claviform is much widened and lengthened, and almost united with a dusky cloud above it (var. plaga, Steph.). This species is sometimes mistaken for A. corticea, but apart from the shorter teeth of the male antennæ, the present species has a distinct, and often conspicuous, black mark on the front of the thorax.

The caterpillar is brownish with darker pear-shaped marks on the back; lines dark edged; spiracles black and of large size. Head pale marked with brown. It feeds from July to May on various low herbage, including lettuce, chickweed, plantain, and goose-foot; also turnips.

The moth flies in June and July (sometimes in September), and is generally common; but in Scotland it does not appear to extend north of Moray and Argyle.
