This straw-coloured species (Plate 144, Fig. 4 [male], 6 [female]) will be easily recognised by the brownish stripe on the fore wings, which extends from the front margin, near the tip, almost to the inner {331} margin; this is sometimes faint, but rarely quite absent. The hind wings are paler and have a dusky central dot and incomplete band. The caterpillar, which in shape is somewhat similar to that of the next species, is ochreous grey inclining to pinkish on the sides; a dark almost blackish line along the middle of the back is edged on each side with pale ochreous, and there are other pale and dark lines along the sides. It feeds on thyme, cinquefoil, yarrow, and other low-growing plants; it may be reared on knot grass: September to June. The moth is out in July and August, and, although very local, is not uncommon on downs and hilly fields on the chalk in Kent and Surrey--Dover, Folkestone, and Rochester in the former county, and Leatherhead, Box Hill, and Reigate in the latter, are the best-known localities. It has also been reported from Sussex (Brighton, Horsham, near Polgate, Shoreham). In Devonshire it is said to occur at Braunton and Ilfracombe, but is scarce. In his catalogue of the Lepidoptera of Suffolk (1890) the Rev. E. N. Bloomfield notes the species as very plentiful in clover fields about Tuddenham. Also recorded from Somerset, Gloucestershire, Cheshire (West Kirby and Hale), and from near Harrow in Middlesex. Very local and scarce in Ireland (Kane). The range abroad extends to East Siberia and Amurland. YELLOW BELLE (_Aspilates ochrearia_). As will be seen from Fig. 5 [female] on Plate 144, this species differs from the last in its yellower colour and rather smaller size; the fore wings have two cross bands, generally well defined, but in the male they are sometimes very faint and slender, and specimens have been recorded in which the bands were missing. The roughened caterpillar, figured on Plate 142, from a coloured drawing by Mr. A. Sich, is pale ochreous brown, lined and striped with darker brown. It feeds on wild carrot, plantain, {332} hawks'-beard, etc., and will thrive on knot-grass. There are two broods, one feeding in the spring, after hibernation; and the other in June and July, sometimes later. The first generation of moths flies in May and June, and the second in August and early September. The species occurs in all the southern seaboard counties of England from Kent to Cornwall, frequenting the downs and rough fields near the coast; also in the Sandbreck district of the eastern counties. It occurs in South Wales; and odd specimens have been reported from Cheshire (Delamere), and from Cumberland. The range abroad extends to North-west Africa and Asia Minor.
