BRITISH AND EUROPEAN BUTTERFLIES AND MOTHS. 



187 



nervure 4 and have the usual markings and 

 a central dot behind tlie first transverse line. 

 It is widely distributed in Central and Southern 

 Europe in June and July. The larva is slender, 

 yellowish grey with dark dorsal lines, a whitish 

 yellow lateral line and fine dark transverse 

 lines. It feeds on plantain, Stachys sylvatica 

 and other low plants till May. The pupa is 

 light brown. 



A. emutaria, Hiibn. The Rosy Wave 

 is white with a rosy tinge, finely dusted with 

 black. There is a row of blackish dots run- 

 ning from the apex of the fore wings to the 

 inner margin, preceded by a pale grey oblique 

 band, and an indistinct grey central dot. The 

 hind wings are sharply angulated. It is found 

 in Southern and Western Europe, appearing 

 in June. 



A. imitaria, Hiibn. The Small Blood-vein 

 is reddish ochreous, with three transverse 

 lines on the fore wings, the two last strongly 

 waved and converging towards the costa. 

 There are two transverse lines on the hind 

 wings, corresponding to these. The central 

 dots are blackish and indistinct. The hind 

 wings are sharply angulated. The larva is 

 long and slender, greenish grey or yellowish 

 with dark dorsal and lateral spots. It feeds 

 on shrubs till June. The pupa is yellowish 

 brown. 



A. ornata, Scop. The Lace Border is 

 snow-white, with the two anterior transverse 

 lines of the fore wings more or less distinct, 

 the first composed of a few dots, the second 

 dusky. There is a black central dot on the 

 hind wings only. The posterior transverse 

 line of aU the wings is dark and slender, with 

 two strong curves towards the base and spot- 

 ted with golden brown. The submarginal line 

 is rendered distinct by its dark borders, till 

 just before the apex. The marginal line is 

 darker between the nervures. The fringes are 

 chequered with lighter and darker. It is 

 common in woods in most parts of Europe 

 in the Autumn. The larva is grey with red- 

 dish longitudinal lines. It feeds on thyme in 

 April and August. 



A. decorata, W. V. PI. XXIX. fig. 4. 

 is common in woods in Southern and Central 

 Europe except the North-West in May and 

 August. 



Genus Zonosoma, Led. 



Middle-sized moth with sharply pointed 

 wings, slightly projecting at nervure 4, with 

 angulated hind wings. The arrangement of 

 the nervures is as in Acidalia, with the exception 

 that nervures 7 and 8 rise from the tip of the 

 appendicular cell and 9, 10, and 11 behind 

 one another from 8, whilst 6 and 7 of the 

 hind wings are shortly stalked. The palpi are 

 very slightly developed, and do not reach to 

 the front. The proboscis is spiral. The 

 antenna; of the males are pectinated, bare at 

 the tip. The legs are smoothly scaled; the 

 hind tibia of the males with only terminal 

 spurs, those of the females with spurs in the 

 middle also. The wings are pale yellow or 

 reddish brown, usually with the orbicular stigma 

 centred with lighter, and concolorous fringes. 

 The moths are double brooded, flying in May 

 and again in July and August. 



Z. pendularia, Clerck. The Birch Mocha 

 is white dusted with reddish grey, with two 

 transverse lines composed of rows of dots, 

 a broad dark-edged orbicular stigma between 

 them, a more or less reddish grey suffused 

 band and a well-marked black marginal 

 line between the nervures. It is common in 

 Northern and Central Europe, especially in 

 birch woods. The larva is very variable, green, 

 brownish or rust-colour with light longitudinal 

 lines, a yellowish one below the spiracles, 

 yellow incisions and oblique streaks. It feeds 

 on birch, alder, hazel, etc. The pupa is conical, 

 obtuse in front, with four short projections at 

 the angles, dotted with green and black, and 

 streaked with black on the wing-cases. It is 

 attached by a thread round the body like 

 the pupae of the Pierida. 



Z. orbicularia, Hiibn. The Dingy Mocha 

 is grey, thickly dusted with brown, with two 

 transverse lines composed of spots, an orbicular 

 stigma on a dark central shade between them, 

 and a black marginal line between the ner- 

 vures. It is local in Central Europe. 



Z. annulata, Schulze. The Mocha is 

 sulphur-yellow, with two brown transverse lines, 

 the anterior of which is twice curved, the 

 posterior very strongly zigzag, broadly shaded 

 with brown on the inner side, with a somewhat 

 brown orbicular spot in the middle of each 

 of the wings, a delicate brown submarginal line
