ACIDAUIDA':. 303 



vonn^'' larva before hybernation seems to I'eed upon her- 

 baceous plants, such as Tormcatilla and mugvvort {Artemisia 

 vulgaris). Very stitt'in its posture when at rest in the day- 

 time, in a perfectly straight position, its head depressed close 

 to the legs, which also are packed closely together and pointed 

 forward. 



Pupa elongate, tapering to the anal extremity, which is 

 hooked; very pale brown; wing- and limb-cases darker 

 brown ; dorsal shade blackish. In a slight cocoon among 

 leaves on the tree. (C. Fenn.) 



The moth hides by day among undergrowth, and is readily 

 disturbed by the beating-stick, and easdy captured ; at dusk 

 it flies of its own accord. Common in woods, especially the 

 more open portions, and found also in lanes and well- 

 wooded hedges throughout the Southern, Eastern, and 

 Western Counties of England ; very scarce in the Midlands, 

 but has been taken in Derbyshire and Leicestershire : also 

 ^:hroughout the more northern counties to Durham and 

 Cumberland; but I find no record for Scotland. Common 

 in Wales, extending to Pembrokeshire ; scarce in Ireland, 

 and usually found only singly, but it has been captured in 

 Wicklow, Waterford, Cork, Kerry, Galway, Westmeath, 

 Cavan, Tipperary. Sligo, and Donegal. Abroad it has a wide 

 rano-e through Central Europe, the South of Sweden and 

 North-east of Spain, the North of Italy, Sicily, Corsica, 

 Dalmatia, Livonia, Southern Russia, Bithynia, Asia Minor, 

 Tartary, China, Corea, and Japan.
