178 European Butterflies and Moths. 



GENUS XXXVIII. — PLASTENIS (BOISD.). 



Rather small moths, with slender bodies, the fore-wings short and broad, brownish, with the 

 pale transverse lines not dentated, and at least two stigmata surrounded with paler ; the subter- 

 minal line slightly indented, and rather indistinct ; hind-wings short and broad, brownish-grey. 

 The antennse of the male shortly ciliated, and the thighs clothed with long hair. The larvae are 

 slender, with small raised spots, and live in May between leaves spun together ; and the moths 

 appear in July and August, and are common throughout Central Europe and Northern Asia. 

 They expand from i to i^ inches. 



* I. P. Retiisa (Linn.). — Fore-wings broad, reddish-brown, and partially dusted with violet- 

 grey, with two pale parallel transverse lines, and two dark stigmata, narrowly surrounded with 

 paler. The larva is whitish-green, with five white longitudinal lines, and a grey head ; it feeds on 

 willow. 



* 2. P. Subtusa (W. v.). — Fore-wings brownish-grey, with two pale transverse lines converging 

 towards the inner margin, and three dark stigmata bordered with paler. The larva resembles that 

 of Retiisa, but has a black head. It feeds on poplars and willows. 



GENUS XXXIX. — CIRRHCEDIA (GU£N.). 



Rather small moths ; the fore-wings broad, with the hind margin rather curved, and the tips 

 prominent ; brown or yellow, with two pale transverse lines, which are not dentated and converge 

 towards the hind margin ; but the orbicular and claviform stigmata are scarcely marked. Hind- 

 wings short and whitish, dusted with reddish towards the hind margin. Antennae and legs as in 

 Plastcnis ; the abdomen scarcely extends beyond the anal angle of the hind-wings. The larvae 

 are short and thick, with a small head, and a horny plate behind. They feed in May, and the 

 moths appear in August and September. 



I. C. Amlmsta (W. V.). — Fore-wings reddish-brown, darker in the central area ; the transverse 

 lines, the subterminal line, and the borders of the reniform stigma whitish. Size of Xeranipelina. 

 Scarce and local in Central Europe, but absent in the north-west. The larva is dirty flesh-colour, 

 with three whitish lines on the back, oblique brownish streaks between, and a yellowish stripe on 

 the sides. It feeds on apple and pear trees. 



* 2. C. Xeranipelina (Hiibn.). — Fore-wings golden-yellow or reddish-grey, the central area 

 nearly to the costa, the reniform stigma, and the hind margin brownish-red ; the transverse 

 lines pale yellow. Expands nearly i^ inches. Extremely local in Central Europe; somewhat 

 commoner in England, France, and Ireland. The larva is greyish-brown, with a yellowish line on 

 the back, black subdorsal lines, and black longitudinal streaks between them ; it feeds on ash. 

 {C. Ulicis, Stand., from Spain, is a third larger ; the fore-wings are longer, the inner line more 

 oblique, and much further from the base on the inner margin, where it nearly meets the elbowed 

 line. Two stigmata are visible between them, and are surrounded with darker ; the orbicular 

 stigma is reduced to a spot. The subterminal line is composed of pale lunules, bordered with 

 dusky towards the base. The male is reddish or yellow, and the female is dull greenish-grey.) 



GENUS XL. — COSMIA (OCHS.). 



Rather small moths, with broad truncated fore -wings, rounded above the hinder angle ; 

 they are brown, yellow, or pale grey, with two pale or dark transverse lines, which arc not
