Its fore wings are grey, with generally either an ochreous or reddish tinge. The orbicular and reniform spots are outlined with a paler colour, and there is a pale transverse line parallel with the hind margin, outside which is a row of indistinct black spots. The hind wings are greyish brown. [Illustration: FIG. 163.--THE COMMON QUAKER.] The caterpillar is green and velvety, with a yellowish line on the back and on each side; and a yellow band crosses the back of the twelfth segment transversely. It feeds during June and July on oak (_Quercus Robur_) and elm (_Ulmus campestris_), and changes to a chrysalis in August on the surface of the ground. In this state it remains throughout the winter, and the moth emerges in March or April. _The Chestnut_ (_Cerastis Vaccinii_) Unfortunately our space will not allow us to notice the whole of even the very common moths, so, passing over a few with great reluctance, we come to the familiar Chestnut, which may be seen at large in October and November, and sometimes even in December, and again appears, after a rather short period of hybernation, in February and March. [Illustration: FIG. 164.--THE CHESTNUT.] The fore wings are reddish brown, with darker wavy lines. The orbicular and reniform spots have pale outlines, and the lower half of the latter is very dark grey. The hind wings are smoky grey, with generally a pale band beyond the middle. The caterpillar is dark brown, with very indistinct lighter lines. The spiracles are black, and inclosed in a yellowish grey stripe. It feeds during June and July on the elm (_Ulmus campestris_), oak (_Quercus Robur_), and sallow (_Salix caprea_), and various low plants. _The Pink-barred Sallow_ (_Xanthia Flavago_) This moth is not nearly so common as the preceding species, but has been taken more or less in all parts of England. Its fore wings are orange yellow, with purplish markings arranged as represented in fig. 165. The hind wings are yellowish white. [Illustration: FIG. 165.--THE PINK-BARRED SALLOW.] The caterpillar is brown, with a lateral stripe formed by numerous red, yellow and white dots. It feeds on sallow (_Salix caprea_) and various low plants. It is full grown in June, and the moth appears in September. Family--COSMIIDAE _The Dun-bar_ (_Calymnia trapezina_) Our example of this family is the Dun-bar, common everywhere during July and August. Its fore wings are greyish ochreous, with a darker band across the middle. On each side of this band is a white line margined with dark grey, and there is a row of black spots along the hind margin. The hind wings are smoky brown, becoming paler towards the base. [Illustration: FIG. 166.--THE DUN-BAR.]
