BRiriSH AXD EUROPEAN BUTTERFLIES AKD MOTHS.

again in August and September. The larva 

 is contracted, generally yellowisli green; hairy 

 with black and white dots, larger on the last 

 segments, and a black dorsal line. It feeds 

 on spurge. The pupa has a fine cocoon on 

 the ground. 



Genus Odezia, Boisd. 



Slender middle-sized moths, with broad 

 rounded black wings, setiform antennae, coar- 

 sely haired palpi, as long again as the head, 

 and a strong proboscis. The antennas of the 

 males are thick and shortly ciliated. Hind 

 tibiae with two pairs of spurs. The appen- 

 dicular cell of the fore wings is undivided; 

 nervure 6 rises from the inner, 11 from the 

 anterior border, of the appendicular cell; 7, 8 

 and ID rise in a point from its tip, g from 

 8, and 3 and 4 are separate. Nervures 3 and 

 4 of the hind wings rise separately; 6 and 7 

 are stalked, and 8 lies on the anterior edge 

 of the discoidal cell to near its end. They fly 

 on mountain pastures in the day-time. 



O. atrata, Linn. The Chimney Sweeper. 

 PI. XXX. fig. 9. is common in meadows in 

 Central and Northern Europe in June and 

 July. The larva is slender, velvety green and 

 without markings. It feeds on Cliarophyllum 

 sylvestre. The pupa has a slight cocoon. 



O. tibiale, Esp. is black with a white 

 band on the fore wings. It is scarce in the 

 mountains of South-Central Europe and North- 

 Eastern Germany in July. The larva feeds 

 on Actaa spicata. 



Genus Lithostege, Hubn. 



Slender middle-sized moths, with somewhat 

 pointed fore wings, narrow at the base, but 

 much expanded externall}', and rounded at 

 the hinder angle. The hind wings are narrow 

 with a very small appendicular membrane at 

 the base of the inner margin in the males. 

 Front somewhat globular. Palpi covered with 

 coarse projecting scales, and slightly projecting 

 horizontally beyond the front. Antennae seti- 

 form, very shortly ciliated in the males. Front 

 femora thick and rather crooked, tibiae with a 

 strong terminal claw, the posterior pair with 

 two pairs of spurs. Fore wings with a divided 

 appendicular cell, projecting far beyond the 

 discoidal cell, from the tip of which nervures 



7 and 8 rise in a point. From the inner border 

 of the appendicular cell, close to the anterior 

 angle of the discoidal cell, rises nervure 6, 11 

 from the anterior border, and g and 10 rise 

 successively from 8. Hind wings without an 

 internal nervure in the males, but with a small 

 appendicular membrane instead. Nervure 2 

 rises from the discoidal cell behind the middle 

 of the inner margin, 3 and 4 wide apart, the 

 former running towards the anal angle; 6 and 

 7 are shortly stalked and 8 rises just in front 

 of the end of the discoidal cell. In the females 

 there is an internal nervure close to the inner 

 margin, and terminating at its middle third; 

 nervure 2 runs into the hinder angle and 3 

 into the hind margin; all the others are as 

 in the males. They fly in the day-time or at 

 dusk, and when at rest have the wings sloping. 



L. griseata, W. V. is pale grey, thickly 

 dusted with yellowish-brown, with a dark line 

 dividing the apex of the fore wings, some- 

 times continued over the whole surface. It 

 is found in Central and Southern Europe in 

 May and July. 



L. farinata, Hufn. The Snowy Carpet 

 is pearly white, with the fore wings finely 

 dusted with bluish-grey. It is scarce in Central 

 Europe in June and July. 



Genus Anaitis, Dup. 



Rather large moths, somewhat resembling 

 the Pyralidai in appearance, with broad fore 

 wings, narrow at the base, and strongly pro- 

 jecting at the apex; and broad expanded hind 

 wings more rounded at the anal angle than 

 at the apex. Body long and slender; palpi 

 coarsely scaled, and projecting beyond the 

 head. Front somewhat flat, usually with a 

 small crest overlapping the palpi. Proboscis 

 long and stout. Antennae setiform, shortly 

 ciliated in the males. Front tibiae with a strong 

 terminal claw [plagiata and prafovmata). Hind 

 tibiae with two pairs of spurs. Males with 

 a long anal tuft. The arrangement of the 

 nervures is as in the last genus. They fly in 

 the day-time in meadows, and have the wings 

 sloping when at rest. 



A. plagiata, Linn. The Treble-bar. Fore 

 wings bluish grey with a rusty brown trans- 

 verse line near the base, expanded into spots 

 on the costa, and two transverse bands
