to Amurland and Japan. THE SMALL SQUARE SPOT (_Noctua rubi_). There are two generations of this species. The first is on the wing in June, and the second in August, September, and sometimes even in October. An example of each brood is shown on Plate 114, Fig. 3, 1st gen., Fig. 4, 2nd gen. The early moths are larger in size than the later ones, but are fewer in number. Moths of the second generation often abound at the sugar patches, and on ragwort blossom. The colour of {227} the fore wings varies from pale to dark reddish brown in both broods. The caterpillar is greyish ochreous or brown, with dark-edged paler lines, and the brown head is marked with darker. It feeds on dandelion, dock, grass, etc. Those of the first generation feed from autumn to spring, and those of the second during the summer. The moth is found in almost every part of the British Isles, except, perhaps, the Hebrides and Shetlands. THE SIX-STRIPED RUSTIC (_Noctua umbrosa_). This species (Plate 114, Fig. 5), is also generally distributed over our islands as far north as Moray, but it is rather partial to marshy situations. The caterpillar, which feeds from August to May on dock, plantain, bramble, bedstraw, etc., is pale ochreous or brownish, freckled with darker, and with dark-edged, pale ochreous lines on the back, the outer ones with a series of black wedges along them; a dark brown stripe low down along the sides; head pale brown marked with darker. The moth flies in July and August. It seems to prefer the flowers of the ragwort and the honey-dew on foliage to sugar, but the latter has attractions for it nevertheless. COUSIN GERMAN (_Noctua_ (_Mythimna_) _sobrina_). On Plate 114, Fig. 6, is a portrait of this greyish suffused purple-brown species, which in the British Isles is seemingly confined to certain localities in Perthshire and Aberdeen, and was first met with in the former county by Weaver in 1853. According to Barrett it is found chiefly in mountain districts from 700 feet above sea-level upwards. The caterpillar is reddish or red brown, slightly mottled with grey; the marking on the back almost linear, widening a little, but narrowly lozenge-shaped near the end of each ring, and {228} having on the widest part a round pale spot of dirty ochreous; sides much mottled with grey; dots and spiracles black, and under the latter a pale pinkish, ochreous, brown stripe; head shining brownish ochreous, with two black dots in front of each lobe. (Adapted from Buckler.) It feeds on heather, bilberry, birch, grass, etc. September to June. The moth flies in July and August. THE SQUARE-SPOT RUSTIC (_Noctua_ (_Segetia_) _xanthographa_).
