The faint reddish tinged pale-brown fore wings distinguish this species (Plate 95, Fig. 5). The blackish marks on the front edge are minute, the cross lines are usually indistinct and often absent; the discal spot, however, is black and conspicuous, and the whitish submarginal line is very wavy. In general colour, the caterpillar is pale brownish; lines and marks on the back, dark brown or blackish. It feeds on the seeds of the nettle-leaved bell-flower (_Campanula trachelium_), and may be reared on the flowers of the various kinds of _Campanula_ grown in gardens: August and early September. {233} The moth is out in July, but is rarely seen in a state of nature. Caterpillars, however, are not uncommon, where the food plant is plentiful, in several of the English counties from Worcestershire southwards to Kent and Cornwall; also in Norfolk. This species is the _campanulata_ of most British authors. JASIONE PUG (_Eupithecia jasioneata_). Except that the ground colour inclines to dark greyish brown, and the cross markings are rather more in evidence, this species is somewhat similar to that last mentioned, pale specimens especially (Plate 95, Figs. 8, 11). The caterpillar feeds in the seed heads of sheep's bit (_Jasione montana_), is very like that of _denotata_ (_campanulata_), and occurs in the same months. Possibly this insect, which is regarded as purely British, may eventually be reduced to varietal rank. As pointed out by Mr. Prout, it is in its paler form not easily separable from _atraria_, Herrich-Schaeffer, a mountain form of _denotata_, Hubner. Whether species or variety, it is equally interesting to the student of British Lepidoptera from the fact that, up to the year 1878, it seems to have been unknown to entomologists. From its close allies, it stands out more distinctly than do _absinthiata_ and _goossensiata_ from each other, and the latter can hardly escape a similar fate if _jasioneata_ is degraded. The moth is out in May and June, but it is very rarely seen at large, though caterpillars are found locally in Devon and Somerset, England; at Barmouth, in Merionethshire, North Wales; and in Cork and Kerry, Ireland. Possibly, it awaits discovery in several other parts of the British Isles, and almost certainly in the west of England. In ascertaining new localities for the species, the best method of investigation would be to search for the caterpillars. {234} WHITE-SPOTTED PUG (_Eupithecia albipunctata_).
