206 BRITISH MOTHS 



in the females ; and the fore wings are entire, with the apical margin rounded. The thorax is not crested, and 

 the larvffi are naked and smooth, attenuated in front, with a small head. They live in a case of leaves 

 fastened together.

This species measures from \~ to 1^ inch in the expanse of the fore wings, which are of a shining hoarj' tinge, 

 with ashy and brown clouds, and a black line at the base. The two ordinary and also the supplemental stigmata 

 are present ; being, however, chiefly indicated by their black and interrupted margins. The apical margin is 

 marked with a row of small black lines ; and the ciliaa are hoary, as well as the hind wings, with a slender black 

 and nearly continuous line along the margin. The cilia3 hoary. Varieties occur in which the fore wings are 

 of a much darker hue, and others brilliantly suffused with purple ; and the hind ones brown or brownisli, with 

 the marginal striga more interrupted. The caterpillar is green with slender pale lines, and a dark varied 

 head. It feeds on willows ; and the moth appears in June or July, frequenting woods. It is not a common 

 species. 



Obs. — The palpi in this species are very short and porrected horizontally ; and the abdomen of the female 

 short and obtuse.

This pretty insect measures from 1^ to 11 inch in the expanse of the fore wings, which are of a pale 

 yellowish buff, with a patch of brownish colour towards the base of the wing, almost obliterating the basal 

 striga, which appears on the costa ; the second striga is very much angulated and pale, edged behind with a 

 reddish-brown line. The characteristic part of the wing bears the three stigmata, the supplemental one being 

 oval and longer than the anterior one. A brownish deeply-elbowed fascia runs through the centre of this part 

 of the wing, resting upon the inner edge of the outer stigma. The third and fourth strigje are distinct, consisting 

 of rows of small dark lunules. The hind wings are almost colourless. Varieties occur in which the ground 

 colour of the wings is much darker. The caterpillar is of a reddish-brown colour, with white lines and oval 

 spots, and the head black. It feeds on the oak ; and the motli appears in May and June, being found on the 

 trunks of trees. It is rather an uncommon, although widely dispersed, species. 



Ohs. — The palpi in this species are ascending, and the abdomen of the female is long and acute. 



COSMIA, OcHSENHEiMEn. COSMIA and EUPERIA, GuiNiE, 

 This genus differs from the preceding in its simple antenna?. The palpi are of moderate length and ascending, 

 with the terminal joint exposed. The thorax is not crested ; and the abdomen is tufted at the apex in the 

 males. The fore wings are truncated, or but very slightly hooked on the apical margin ; they are deflexed in 

 repose, and are marked in the middle with a trigonate or trapeziform patch. The larvse are green striped with 

 white ; they are elongated, attenuated towards the head, with a small bead ; living amongst the leaves of trees. 

 M. Guenee separates the 0. trapezina fulvago, and some other allied species, into a separate genus under the name 

 of Euperia, considering them as far removed in the system from the other species. (Ann. Soc. Ent. France, 1839, 

 p. 487.)
