170 European Butterflies and Moths. 



The only species, * A. Lutiosa (Haw.), is dark grey, with the transverse lines and nervures yellow, 

 and the subtcrminal line bordered inside with triangular black spots, which are most distinct 

 towards the costa. Stigmata brownish-black, bordered with yellow. Hind-wings shining white, 

 with a discoidal lunule, and a marginal row of more or less distinct blackish spots. Expands 

 about \\ inches. It appears to be confined to Britain, France, and Spain, and occurs from 

 July to September. The larva is greenish, with white longitudinal lines, and lives on grass 

 in dry elevated localities in April. 



GENUS XXV. — RUSINA (BOISD.). 



Body rather stout, fore-wings with the hind margin a little oblique, and curved behind, 

 and the fringes rounded ; the stigmata are indistinct, and the claviform stigma is absent ; the 

 hind-wings are broad, the last joint of the palpi is straight, and the abdomen is short. The 

 only species, * A'. Tcucbrosa (Hiibn.), has russet-brown fore-wings, with a yellowish lustre, and 

 two single slender black transverse lines, rising from white costal spots; the subterminal line 

 is indistinctly edged with white, and broken into spots, and the hind-wings are grey. Expands 

 about i^ inches. Widely distributed in Europe in June and July. The larva is thick, reddish- 

 brown, with the back redder, and marked with three pale lines, between which are oblique 

 blackish dashes, and a grey stripe on the sides. It feeds on low plants in autumn, and 

 hybernates when full-grown. 



GENUS XXVI. — ASTEROSCOPUS (BOISD.). 



Rather large moths, resembling Boinbyces, to which many authors refer them, placing them 

 among the Notodontidm. Fore-wings rather long, with a long curved oblique hind margin, 

 and the fringes slightly convex. They are grey, with dark longitudinal stripes ; the hind-wings 

 are small, with a dark spot in the middle ; the abdomen extends much beyond the anal 

 angle, and is tufted on the sides. The larvae are thick and naked, with the last segment but 

 one somewhat raised, and when at rest they erect the front part of their bodies ; they change 

 to pupae in the ground. In the first species the tongue of the moth is rudimentary, and 

 the stigmata are indistinct ; in the second, which forms the genus Selenoscopiis (V. Hein.), the 

 tongue is short and weak, but spiral, and the three stigmata are well marked. 



*i. A. Sphinx (Hufn.), Cassinea (W. V.). — Fore-wings pale grey, varied with brownish 

 yellow, with many short black longitudinal dashes, and a small oblong orbicular stigma 

 surrounded with black ; hind-wings greyish, with the nervures and a round central spot brown. 

 Expands about l| inches. Common in Central Europe in October and November. The 

 larva is yellowish-green, with three white lines on the back, and a yellowish-white stripe on 

 the sides, shaded with dusky above. It lives on willow, lime, &c., from May to August. The 

 moth is figured at PI. 33, Fig. 7. 



* 2. A. Njtbeciilosa (Esp.). — Fore-wings dark ashy-grey, varied with darker grey, with two 

 light transverse stripes, not sharply defined, the last oblique and zigzag, and placed very far 

 back. The nervures are thick and black, and the three stigmata are broadly surrounded 

 with black ; the orbicular stigma is small, and the reniform stigma is very large, and filled 

 up with whitish-grey above ; the hind-wings are dusted with brown. Expands from i to 

 if inches. A scarce insect, occurring in the north of Central Europe in March and April. 

 The chief British locality is Rannoch, in Perthshire. The larva is green, with a perpendicular 

 yellow dash on the sides of the 4th segment. It feeds on birch, elm, &c., from May 

 to July.
