The caterpillar is reddish brown, with a slender line of white dots on the back, and a similar line on each side. The body is smooth and velvety, and is netted and dotted all over with dark brown. It feeds on the lady's bedstraw (_Galium verum_), sweet woodruff (_Asperula odorata_), and many other low plants; and is full fed early in July. _The Lesser Broad Border_ (_Triphaena ianthina_) We now come to the third and last genus (_Triphaena_) of this extensive family, a genus which includes six interesting moths, with bright orange or yellow hind wings. Of these we shall take three examples. [Illustration: FIG. 159.--THE LESSER BROAD BORDER.] The first of them--the Lesser Broad Border--has fore wings of a rich reddish or violet brown, with paler markings. The hind wings are bright orange, with a broad marginal band of black. It is a common moth, particularly in the south-western counties, and flies during July and August. The caterpillar is of a dingy yellowish or greenish grey, with a light line down the back, and two black spots on each side of segments nine to twelve inclusive. It feeds throughout the winter by night on dead nettles (_Lamium purpureum_ and _L. album_), primrose (_Primula acaulis_), whitethorn (_Crataegus oxyacantha_), blackthorn (_Prunus spinosa_), and various low plants; and may sometimes be seen in flower gardens. It is full grown in April. _The Lesser Yellow Underwing_ (_Triphaena Comes_) This insect is very similar to the last, but is larger. The fore wings are also of a greyish or ochreous brown, and the black margin of the hind wings is proportionately narrower. [Illustration: FIG. 160.--THE LESSER YELLOW UNDERWING.] It is more abundant than _Ianthina_; in fact it is to be found everywhere in plenty during the month of July. The caterpillar is yellowish brown. On the back of each of the eleventh and twelfth segments are two conspicuous dark marks. The spiracles are white, and below them is a pale brown stripe. It feeds on the foxglove (_Digitalis purpurea_), chickweed (_Stellaria media_), thrift (_Armeria maritima_), and other low plants in the autumn, hybernates during the winter, and attacks sallows (_Salix Caprea_ and _S. cinerea_) and whitethorn (_Crataegus oxyacantha_) as soon as the buds appear in the spring. It is full grown in April, and then changes to a chrysalis on the surface of the earth. _The Large Yellow Underwing_ (_Triphaena Pronuba_) This is by far the commonest moth of the genus, and may be found everywhere, in town and country, from June to August. It is represented on Plate XI (fig. 1), but its fore wings are very variable, sometimes a cold dingy grey, but often of an exceedingly rich and warm brown. On the costal margin, not far from the tip, there is always a small black spot, which will serve to distinguish it from _Comes_.
