The caterpillar feeds on dead oak leaves, chiefly those that have fallen to the ground. After hibernation it becomes full grown about June, and is then brown with a downy appearance; there are three faintly darker lines along the back, and the usual dots are dusky. (Plate 34, Fig. 3; after Hofmann.) The moth is out in June and July, and in the daytime may be put up from its lurking place among herbage in wood clearings, or netted as it flies in the gloaming. It is also attracted by sugar and light. The species has been erroneously recorded from Chester and Barmouth (North Wales); and Mr. Carr informs me that he is not quite sure that a specimen he recorded from Dawlish, South Devon, was correctly identified. In the catalogue of Malvern Lepidoptera _H. derivalis_ is stated to be rather common in that district, but the occurrence of the species in the Midlands requires confirmation. Abroad, the range extends to Amurland. THE COMMON FAN-FOOT (_Pechipogon barbalis_). The fore wings of the species shown on Plate 35, Fig. 7, are greyish brown, crossed by three darker lines, the outer one almost parallel with the hind margin, and edged with whitish. The caterpillar feeds on the dead leaves of oak and birch, and has almost attained full growth when it retires for the winter. In the spring it has been known to eat birch catkins. The general colour is reddish ochreous, with diamond-shaped markings, forming a series along the back and two series along each side. {92} The moth, which is out from late May until early July, frequents the more open parts of woods, and in the daytime may be induced to show itself by tapping the lower branches of trees or brushing the bushes and undergrowth as we pass along. The species is widely distributed over England, from Staffordshire southwards, but it is apparently most frequently met with in some of the woods of Kent, Surrey, and Sussex. The distribution abroad extends to Amurland. THE BEAUTIFUL SNOUT (_Bomolocha fontis_). The portraits of this species on Plate 35 show each sex in its most usual form: Fig. 8 representing the male, and Fig. 9 the female. The outer and inner areas of the fore wings are generally ashy grey, more or less brownish tinged, in the male; and the same parts are whitish in the female. Although some examples of the male have the outer and inner areas whitish, as in the female, they can be distinguished by their darker hind wings and the blackish central crescent thereon. A form of the female in which the large central patch of the fore wings is reddish brown has been named _rufescens_, Tutt; there may be males also of this form, but I have not seen any. In both sexes, the brown patch extends nearer to the inner margin in some specimens than in others, and not infrequently there is a spur from the lower edge of the patch to this margin.
