64 LEPIDOPTERA. 



incisions of segments darkened. In a brittle cocoon of earth, 

 and a very little silk, beneath the surface of the ground. 



The moth conceals itself among dead leaves and dense 

 herbage in the daytime, but flies at dusk and is very strongly 

 attracted by sugar, but apparently very little so by flowers 

 or light. It is almost confined to woods and usually plentiful 

 in such situations throughout the south of England to Corn- 

 wall, in the Eastern counties, the Southern Midlands, and the 

 Western counties to Lancashire ; also in StaflTord shire, Derby- 

 shire, and Yorkshire, and to be found in Cumberland. In 

 Wales it surely occurs in all wooded districts, for I have found 

 it in Pembrokeshire, In Scotland it is common in Ross-shire, 

 and found in the districts of the Tweed, Solway, Forth, Clyde, 

 in Perthshire, Aberdeenshire, Moray, Argyle, probably 

 throughout the mainland, and certainly in the Hebrides and 

 the Orkneys, sometimes producing very dark forms. In 

 Ireland also it is widely distributed, and rather variably, 

 occurring near Dublin, in Wicklow, Waterford, Kerry, Galway, 

 Sligo, Westmeath, Monaghan, Tyrone, Armagh, Antrim, and 

 Londonderry. Abroad it is found generall}' through Central 

 Europe, all Northern Europe except the coldest portions. 

 Western Siberia, the Ural Mountain district, China, and 

 Japan.
