The caterpillar is greyish or greenish grey, inclining to brownish above, and with darker brown marks on the back; lines paler, edged sometimes with darker grey; raised spots blackish, rather glossy; head brownish, marked with black, and the plate on first ring is black with a central yellow line. It feeds from August to May on various low plants growing in rocky places by the sea. Will eat dandelion, plantain, and knotgrass in confinement, also sliced carrot. THE COAST DART (_Agrotis_ (_Euxoa_) _cursoria_). The specimens whose portraits will be found on Plate 106 are more or less typical of the sexes of this most variable species. The ground colour of the fore wings ranges from whitish ochreous through all shades of brown up to dark reddish, and from whitish grey through leaden grey to brown grey. The markings, too, are exceedingly variable; the cross lines are often faint, sometimes entirely absent; the stigmata are frequently obscure, and occasionally the blackish lower part of the reniform is the only indication of these marks. There is often a white streak along the costa, and in some specimens this is very conspicuous (Figs. 3[male], 4[female]). The caterpillar feeds from September to June on various grasses growing on sandhills, and is said to eat wormwood and violet. It is ochreous in colour, more or less tinged with green; the lines are pale grey, edged with darker grey; spots brown, and head ochreous brown. The moth is on the wing from late July to early September, and is to be found on all the larger tracts of sandhills on the east coast from Suffolk northwards, and on the coasts of Cheshire and Lancashire. It is not common on our southern coasts, but occurs in Dorsetshire and Devon. In Scotland it is obtained {207} on the Firth of Forth, Kincardine, and Aberdeen coasts, and also in the Hebrides, Orkney, and Shetland Isles; and on very many parts of the coast of Ireland. THE GARDEN DART (_Agrotis_ (_Euxoa_) _nigricans_). This moth is typically sooty or blackish brown in both sexes (Plates 106, Figs. 5[male], 6[female]), but varies to pale brown, or through various shades of red brown. The markings, usually obscure, occasionally are well defined, and sometimes there are additional black spots and pale streaks. The caterpillar is pale or dark ochreous brown on the back, inclining to greenish on the sides; lines greenish grey, edged with black, and a double whitish one low down on the sides. It feeds from September to June, on clover, plantain, dock, and various other low plants; and also cow-parsnip and other umbelliferæ. The moth flies in July and August, and is to be found in most English counties, but perhaps most commonly in the eastern. In Scotland it ranges to Moray, and seems to be generally distributed in Ireland. THE WHITE-LINE DART (_Agrotis_ (_Euxoa_) _tritici_).
