i82 LEPIDOPTERA. 



It was recognised and recorded by Mr. W. Warren in the 

 year 1887, having been until then, to all appearance, confused 

 with the next species. It flies rather high over spruce and 

 silver firs in the sunshine, in the middle of the day and till 

 evening ; and it may occasionally be baaten out of the same 

 trees. So far as I am aware the range of this species with 

 ns is confined to Kent, Surrey and Dorset, but there is little 

 doubt that it will be found in other southern districts when 

 looked for in suitable places and among its favoured trees. 

 Abroad it is found over the greater part of Central Europe, 

 Central Italy and Croatia.
