42 LEPIDOPTERA. 



Lancashire and Cheshire this variety has become unfor- 

 tunately very rare, and in most of its old haunts (|uite 

 exterminated. The ordinary time of flight is, as in the other 

 species, at dusk, and it appears to be especially restless and 

 readily disturbed from its hiding places for a short time 

 before sunset. Still rather widely distributed on heaths, and 

 even on chalk downs, in Kent, Sussex, Surrey, ]laiits, 

 Dorset, and Berks, but hardly known in the Eastern, 

 Western, or Slidlaud Counties. In Cheshire it was formerly 

 found near ]5owden ; and in Lancashire in the extensive 

 region of heath and bog known as Chatmoss ; but its present 

 range or even existence in these Counties is somewhat 

 problematical. In Yorkshire it was found at Thome Moor 

 in the year 1881, and doubtless still exists. I know of no 

 record of its occurrence in Wales, Scotland, or Ireland. 

 Abroad its distribution is not wide — Central Lurope, Finland, 

 and Dalmatia ; bnt Staudinger describes a local variety — 

 which however bears no resemblance to our var. circdlata — 

 as occurring in France and Belgium.
