SCARCE BLACK ARCHES. {143} This is the only really variable species among the five occurring in this country. In some specimens the space between the cross lines is largely filled in with dark grey, and in other specimens the wings are almost entirely white, traces of the cross lines being the only markings. Mr. Robert Adkin, who has reared this species from the egg, kindly allowed me to select specimens from his fine series to illustrate the range of aberration; these are figured on Plate 73. Caterpillar brownish inclining to purplish, with an ochreous line along the middle of the back and some brown V-shaped black marks. Head blackish brown. It feeds in May, after hibernation, on various clovers, preferring the blossoms, and bird's-foot trefoil (_Lotus corniculatus_). The moth appears some time between mid-July and mid-August. The late Mr. Tugwell, by keeping some larvæ, reared from the egg, in a warm room induced them to feed up instead of hibernating, and they attained the moth state in December. This is another exceedingly local species in England. It was first taken at Bembridge in the Isle of Wight in 1858, and one or two specimens have since been obtained in that island. Examples have also occurred on the cliffs near Hastings, and at Folkestone; and one has been recorded as taken in a light trap at Woodbridge in Suffolk, July 21, 1904. The headquarters for the species in this country are the Deal sand-hills, on the Kentish coast, where it was discovered over a quarter of a century ago, and probably occurs still. CHLÖEPHORIDÆ. Authors are not at all agreed as to the systematic position of this family, and there seems to be some difference of opinion as to the species that properly belong to it. Sir George Hampson {144} has transferred the group to the Noctuidæ and separated _S. revayana_ from the others, placing it in his sub-family Sarrothripinæ, to which also belong certain Indian species.
