The fore wings of this species are pale ochreous brown, inclining to pale reddish on the outer marginal area; the most distinct markings are a pale cross band beyond the black discal dot, and a pale winding submarginal line. The hind wings are smoky grey, with whitish wavy cross lines, the most distinct being the outer (Plate [97], Fig. 9). The stoutish and somewhat

stumpy caterpillar is green, or pale yellowish brown, with three darker lines and marks on the back; a yellowish line low down on the sides. It feeds on flowers and seeds of orache (Atriplex), and goosefoot (Chenopodium): August and September. Figured on Plate [94], Figs. 1, 1a, from coloured drawings by Mr. A. Sich. In July, the moth may be disturbed from its food plant or adjacent herbage, or it may be seen resting on palings or fences. It flies at night, and will come to light.

Not uncommon in many places in the southern half of England, and found in the rest of the country, chiefly on the coast, to Hartlepool in Durham, also in Wales. Once recorded from south Scotland, and only noted from the coast near Dublin, in Ireland.

Scarce Pug (Eupithecia extensaria).

The conspicuously marked insect represented on Plate [97], Fig. 12, is, so far, only known to occur, in Britain, on the coasts of Norfolk and Yorkshire. It was first discovered in the latter county more than thirty years ago; about twelve years later it was found on the Norfolk coast, and caterpillars were also obtained from the sea wormwood (Artemisia maritima) in the autumn.

The long caterpillar, which feeds on the flowers and foliage of its food plant, is green, with three lines along the back, the central one dusky and the others whitish; a white stripe low down along the sides is edged below with rosy brown. It will thrive on the cultivated southernwood or "lad's love" (Artemisia abrotanum).

The moth is out in June and July, and may be found in its haunts among the sea wormwood, not only on the coast of Norfolk, but quite possibly, here and there, in suitable places on the east coast from Essex to the Humber. Caterpillars may be obtained in August and September.
