The grey, or greyish-brown lined, whitish species shown on Plate 97, Fig. 14, has been known by three names in Britain. It was named and described by Stephens, in 1831, as _piperata_ (The Speckled Pug), from a specimen, or specimens, taken at Riddlesdown, near Croydon, Surrey; later, it was supposed to be the _subumbrata_, of the _Vienna Catalogue_ (1776), and certainly of Guenee. The name given to it by Borkhausen, in 1794, appears to be the correct one, and is here adopted. Crewe describes the caterpillar as yellowish green, with three dark lines on the back, the outer one not clearly defined; a yellow line on each side of the head, and of the last ring of the body. It feeds on flowers of one of the hawkbits (_Leontodon hispidus_), and hawk's-beard (_Crepis taraxacifolia_), etc., from July to September. In June and early July, the moth may be started up from the herbage, as the collector walks over rough ground inland, or more frequently on the coast. It also occurs in fens, marshy places in woods, etc. The species occurs in Bucks., Berks., Surrey, and in the seaboard counties from Norfolk in the east to Gloucestershire in the west, also in South Wales; in the north it is found in Lancashire, Yorkshire, Durham, and Northumberland. It is not common in Scotland, but has been reported from various parts, extending from Wigtown to Argyll and Aberdeen. In Ireland it is also a coast insect, from Donegal to Cork. HAWORTH'S PUG (_Eupithecia haworthiata_). The fore wings of this species (Plate 98. Fig. 2) are pale greyish, with dark cross lines, and still darker narrow bands; hind wings, similar, but markings less distinct. Resembles {243} the last species in size, but the wings are somewhat rounder, darker, and not so silky in appearance; the body, near the thorax, is ochreous brown. Also known as _isogrammaria_, Herrich-Schaeffer, but _haworthiata_, Doubleday, is stated by Prout to be the older name. In July and August the caterpillar (Plate 90, Fig. 3) may be found in the flower-buds of the traveller's joy or old man's beard (_Clematis vitalba_). It is green, with a bluish or pinkish tinge, and there are generally three darker stripes along the back, but these are sometimes absent; occasionally the ground colour is yellowish. The moth is out in June and July, and may be seen flying about clematis in the sunshine, but such specimens are not often worth taking. It is easily reared from caterpillars, which will thrive on flowers of garden _Clematis_, and may be obtained by the score, either by beating, or by searching for discoloured or black-specked flower buds of the traveller's joy. The species is most frequent in the south of England, but it occurs in all the eastern, some of the midland, and also in the northern counties to Lancashire and Yorkshire; in the last-named county, Porritt states that the caterpillars were found in profusion on _Clematis_ near Wadworth, Doncaster, in 1901, It inhabits South Wales and Ireland.
