336 European Butterflies and Moths. 



brown, with a pale line on the back, and white warts. It feeds on oak in May. {P. Ncriaria, 

 Herr.-Schaff, from Greece and Asia Minor, appears to be a variety with a better-marked central 

 spot on the fore-wings, and the blotch at the hinder angle small, and composed of two white 

 spots bordered with red ; the white lines are also less dentated. P. (.') Pliisiaria, Ramb., from 

 Andalusia and Algeria, is light green, with the nervures, the broad dentated transverse lines, the 

 subterminal arrow-headed spots, and hind-wings all silvery-white ; the central spot of the fore- 

 wings is green, broadly suirounded with white, and there is a long white spot below it, towards 

 the inner margin. Expands about i^ inches.) 



GENUS LXIV. — EUCROSTIS (HUBN.). 



Antenna; short, pectinated in the male, and dentated in the female. The only European 

 species, E. Indigcnata (Vill.), has uniform dark velvety-green wings, without lines, but with a 

 small dull reddish dot in the centre of each wing. The fringes are broad, dull purplish-red, edged 

 inside with a darker line, preceded by a yellow stripe. The costa and inner margin of the fore- 

 wings are also yellowish. Expands about three-quarters of an inch. Inhabits South Europe and 

 Western Asia in spring and autumn. The larva is green, j^ellowish below, with yellow incisions, 

 and the first and last segments slightly washed with reddish. It feeds on different species 

 of Eufhorbia. 



GENUS LXV. — NEMORIA (HUBN.). 



Wings green, with white transverse lines ; broad, and entire or waved ; hind-wings with 

 the inner margin generally longer than the costa. The larvae are slender and rigid, with a 

 bifid head, and two anal points. They undergo their transformations in a slight cocoon. 

 Several species which otherwise closely resemble each other differ considerably in structure. 

 In some the antenna; are pectinated, and in others they are simple ; and the hind tibiae 

 have two spurs in some species, and four in others. 



I. N. Fimbrialis (Scop.), Thyiiiiaria (Lmn.), Bupletiraria (W. V.). — Wings leaf-green, with pale 

 fringes spotted with brownish-red, the fore-wings with two narrow white and slightly waved 

 transverse lines, the second continued on the hind-wings. The hind margin of the hind-wings 

 is dentated, with a large excavation above the middle projection ; and the palpi are extremely 

 short. Expands nearly \\ inches. Inhabits Central and Southern Europe, and Western 

 Asia, in July and August. The larva is green, with a rose-red line on the back, and red 

 points behind the head, and on the last segment. It feeds on thyme, yarrow, &c., in May 

 and June. The moth is figured at PI. 50, Fig. 8. 



*2. N. Strigata (Miill.), Aistivaria (Hiibn.), Thyiniaria (Guen.). — Very like Fimbrialis, 

 but the hind-wings are scarcely dentated, and their hind margin forms almost a right angle, 

 with a projecting point in the middle ; the costa of the fore-wings is finely speckled with 

 brown, and the palpi are not remarkably small. Expands from i to 1 4 inches. Common 

 throughout Central and Southern Europe from June to August. The larva is greyish-green, 

 with a dark line on the back, and dark angular marks. It feeds on oak and hazel in May 

 and June. 



3. N. Fanstinata (Mill.). — Wings green, covered with very fine and ill-defined whitish 

 striae, the transverse lines dark green, and nearly straight, forming small angles on each 

 side, two of which, on the second line, are larger than the others ; on the hind-wings the 

 second line is complete, but the inner line is only indicated on the inner margin. There
