Two forms of this species are shown on Plate 35. The typical one is represented by Fig. 12, and Fig. 11 shows ab. _palpalis_, Tutt (?), Fabr. and Stephens. The front margin of the fore wings is often streaked with a pale colour, and in ab. _radiatalis_, Hubner (134), which is otherwise similar to the last-named form, this is pale or ochreous brown. A uniform pale greyish form has been named ab. _unicolor_, Tutt, and one almost entirely ochreous or greyish-ochreous, ab. _ochrea_, Tutt. The caterpillar is green, with blackish dots; a darker line along the middle of the back, and white lines along the sides; head, yellowish green dotted with black. It feeds on hop (_Humulus lupulus_) in June and early July, and in the daytime may be found on the undersides of the leaves. (Plate 37, Fig. 2; after Hofmann.) The moth is out in August and September, and after hibernation reappears in the spring, and may be met with until June. It may be obtained at sugar, or at ivy bloom. Given the food plant, the species will probably be found in most of the counties of England from Worcester southwards, but its occurrence northwards appears to have been very rarely noted. The range abroad extends to East Siberia. THE WHITE-LINE SNOUT (_Hypenodes taenialis_ (_albistrigalis_)). This species, and also the two immediately following, are so small in size, and so obscure in appearance, that they are {95} probably more often neglected than secured when met with. The moth under consideration, and of which the sexes are figured on Plate 36 (Figs. 3 [male] and 4 [female]) has brownish fore wings which are crossed by two rather irregular blackish lines, sometimes hardly traceable on the front margin; the outer line is edged externally with whitish, and the space between the lines is often somewhat darker; the black central mark is more or less X-shaped. The caterpillar does not seem to have been noted in this country, and it is not well known on the continent. It is said to feed on the flowers, chiefly the withering ones, of heather and thyme, in August and September. The moth is out in July and early August, sometimes in September. Its haunts are the edges of woods, hillsides, and sloping banks, where there is plenty of bushes and herbage to hide in. From such retreats it may be disturbed, but is more easily obtained at sugar, or honey dew, and sometimes at ivy bloom. It is widely distributed over the southern half of England; occurs in South Wales, and has been recorded from Cheshire and Yorks. Abroad, the species is found in Holland, Belgium, Germany, Austria, Armenia, and the Canaries; also recorded from south Sweden and Corea. THE PINION-STREAKED SNOUT (_Hypenodes costaestrigalis_).
