This species (Plate 132, Fig. 5) is usually found in marshy localities, or in gardens, over the eastern counties, and from Northamptonshire through Bucks, and Hertfordshire, to Kent, and Surrey. The caterpillar feeds from September on the shoots of _Phalaris arundinacea_ and the cultivated form of that plant grown in gardens, and known as ribbon grass. Also said to feed on _Poa aquatica_. When the grass dies down in the late autumn the caterpillar enters the ground to hibernate, and {275} emerges in the spring ready to attack the young grass shoots as soon as they appear. Where the new growth of ribbon grass assumes a brown and withered appearance this larva will probably be found at the bottom of the trouble. When nearly full grown it eats down the interior of the thicker stems to the base. In colour it is ochreous with a pinkish tinge; a pale brownish plate on first and last rings, each edged with blackish and that on the first ring traversed by a white line; head pale brown, glossy. The moth flies in July and August, sometimes in June. THE MARBLED MINOR (_Miana strigilis_). Half a dozen specimens are shown on Plate 134, and these will serve to give some idea of the range of aberration in this species. The most typical of the species are those represented by Figs. 1 and 4; the farthest removed from the type is var. _æthiops_, Haworth (Fig. 16). In the reddish var. _latruncula_, Hübn., as figured by him, the most conspicuous character is the white lower curve of the second cross line, as in Fig. 7. The caterpillar is purplish brown above, and ochreous below; striped on the back with pale yellow, and less distinctly on the sides; spiracles black and very distinct; head and plates on the first and last rings of the body ochreous brown and shining. Found in March and April, after hibernation, feeding on the stems of various grasses. The moth is out in June and July, and may frequently be seen at rest on palings, etc., but at night it often abounds at sugar or honey dew. Generally distributed in the British Isles, except perhaps in the islands of Scotland. THE MIDDLE-BARRED MINOR (_Miana fasciuncula_). In its typical form this species (Plate 134, Fig. 3) has the fore wings reddish ochreous, with a darker central band, and {276} the cross lines, especially the second, distinctly white towards the inner margin. Sometimes, chiefly in Scotland, the ground colour is much paler, occasionally almost whitish, and the band reddish (var. _cana_, Staud., Figs. 5, 8). There is a good deal of variation, both in the ground colour and in that of the band; the latter is often smoky brown in pale specimens of both sexes.
