Portraits of two specimens of this very local species, kindly lent by Mr. R. Adkin, will be found on Plate 13, Figs. 4 and 5. {42} The general coloration is usually silvery grey, but occasionally it inclines to yellowish. The moth has rarely been noted by day, and only one specimen seems to have been captured on the wing. Even caterpillars are by no means common in their best-known localities, and of those obtained after much labour a large proportion may frequently prove to have been the victims of parasitic flies. The caterpillar is green, inclining to olive green, thickly freckled with pale yellow atoms; a purplish-brown stripe along the middle of the back and two faint purplish lines along the sides; a pale yellow line along the region of the black-edged spiracles, which are set in purplish-brown blotches. (Adapted from Buckler.) Its food plant is golden-rod (_Solidago_) and it feeds at night and hides by day, low down on the stems or under the leaves: July to September. In confinement the caterpillars will eat garden aster and Michaelmas daisy. The British haunts of the species are chiefly in Kent (Sevenoaks, Tunbridge Wells, etc.), and Sussex (Tilgate Forest, etc.); but according to Barrett it is also known from Hampshire, Surrey, and Essex. Abroad, the range extends through Central Europe to Southern Scandinavia, Livonia, Southern Russia, the Altai Mountains, Italy, and Armenia; but the species is nowhere plentiful. It may be mentioned here that a very closely allied, and on the Continent common, species--_C. xeranthemi_, Boisduval--might easily be mistaken for _C. gnaphalii_. THE WORMWOOD (_Cucullia absinthii_). This moth is shown on Plate 16, Fig. 4. The fore wings are usually tinged with purplish over the greyish ground colour; black dots on the stigmata give to each of these marks some resemblance to the figure 8. {43} The caterpillar, which feeds on the flowers and seeds of wormwood (_Artemisia absinthium_) and will eat mugwort (_A. vulgaris_), is best found on sunny days. It is yellowish green, suffused with purplish grey on the back of each ring; there are three pale green lines along the back, and an ochreous grey plate on ring 1. To be found in August and early September, but on dull days it must be sought for among the lower leaves, or on the ground. When resting among the flowers it so closely harmonises with them that it might easily escape detection. The moth is out in July. The species is perhaps most abundant on the South Devonshire coast, but its range extends into Cornwall, and eastward to the Isle of Portland and the Isle of Wight; it is not uncommon along the coasts of North Devon (Lee and Croyde), Somerset (Minehead), and South Wales. It has also been recorded from North Wales, and from parts of the Suffolk coast. In Ireland, a specimen was taken in a garden at Cromlyn, Westmeath, in 1873, and more recently two specimens of the moth, and also some caterpillars, were obtained at Timoleague, Cork.
