244 LEPIDOPTERA. 



female sits in similar situations, but conceals itself closely 

 and is hard to find. The male flies at late dusk, apparently 

 about the trees, since it is then seldom captured on the wing. 

 Almost confined to oak-woods, and parks largely planted 

 with oak timber ; and in such situations to be found, locally, 

 sometimes abundantly, almost throughout England, though 

 but rarely in Cornwall. In Wales I have found it commonly 

 in one oak-wood in Pembrokeshire; but find no other records. 

 In Scotland it occurs in a similar local manner in the 

 Southern districts, extending to Aberdeenshire in the East 

 and to the Clyde Valley in the West. In Perthshire Sir 

 Thomas Moncriefie found it commonly, and noticed that at 

 MoncriefFe Hill it seemed particularly attached to the syca- 

 mores. In Ireland its presence is doubtful. Abroad it 

 occurs throughout the greater part of Central Europe, in 

 Central and Northern Italy and Galicia ; but must also have 

 been surely overlooked in some parts of Asia, since it 

 occurs in similar varieties, and sometimes in larger size, in 

 Japan.
