The moth flies in May and June, and is only to be found on hills and downs in chalk or limestone districts. It occurs in Surrey, Dorset, Isle of Wight, Devon, Gloucestershire, Herefordshire, North Wales, Berkshire, Oxfordshire, Cambridge, and Suffolk; it seems to have been most frequently met with in Kent and Sussex. The small form, with narrow and distinctly marked fore wings, and whitish hind wings, occurring in the south of England, has been named var. _tephrina_, Staud. THE SHUTTLE-SHAPED DART (_Agrotis_ (_Euxoa_) _puta_). As will be seen by the figures on Plate 104, the sexes of this species also differ greatly in colour. Usually the cross lines on the fore wings of the male do not show up so distinctly as in {205} Fig. 2, which closely approaches a form figured and described as _radiola_ by Stephens in 1829. Fig. 5 represents the typical blackish-brown female. Gynandrous specimens, one side [male] the other [female], have been recorded. The caterpillar feeds on dandelion, lettuce, knotgrass, and other low-growing plants, from September to April; probably full grown before hibernation. The moth, which is out in July and August, sometimes in May, is partial to low-lying, marshy ground and meadows, and is widely distributed over the whole of the south of England, but it is seemingly rare in the north, and still more so in Scotland and Ireland. Barrett states that it has been found commonly in Carmarthenshire, Wales. THE CRESCENT DART (_Agrotis_ (_Euxoa_) _lunigera_). Although its position in classification is that of a local form of _A. trux_, Hübn., this moth, which is figured on Plate 105, Figs. 1[male], 2[female], may here retain the name that was given to it by Stephens in 1829. Except that it has been reported to occur in the north of France, it seems to be peculiar to the British Isles. The earliest known specimens were captured near Cork in Ireland, June, 1826, and it is now found not only on the coasts of Cork and Kerry, but also on the Hill of Howth, near Dublin. In England it occurs in the Isle of Wight, Dorsetshire (Portland), Devonshire (Torquay), Cornwall, and the Scilly Isles. Reported from Sussex in 1918. In Wales it is to be found above Barmouth, and in various parts of South Wales; and in Scotland around Edinburgh and on the Moray coast. The moth is out in July and August. Mr. A. E. Gibbs, writing of this species in Cornwall, remarks, "It is generally stated that _A. lunigera_ is only to be taken on steep and dangerous cliffs, in places where sugaring is by no means a safe occupation; but its abundance at Polzeath showed that this is not invariably the case. Here it was found on posts and flower heads in the valley at some {206} distance from the seashore, and so abundantly did it occur that one evening's work yielded upwards of fifty specimens."
