no THE SCOTTISH NATURALIST 



Buckinghamshire, and the Island of Jura (Ebudes South) ; 

 in 1909 in Hertfordshire, Oxfordshire, and Staffordshire; in 

 1910 in Perth North; in 1912 in Surrey; and in 1915 in 

 Shropshire ; and it has also been found in Northamptonshire 

 — altogether six Scottish and eleven English counties, five of 

 these forming a ring encircling London. The secret of its 

 occurrence is its preference for aboriginal forest, pine in Scot- 

 land and the north of England, beech in the south ; and it 

 does not occur in modern plantations, so would seem doomed 

 to ultimate extinction as a component of the British fauna, 

 when and as the old forest tracts fall under the axe of the 

 woodman. 



Var. cerea is the common and prevalent form at Rothie- 

 murchus, and elsewhere. Of var. fulva, a few with type at 

 Rothiemurchus, 29th August 1904 (R. Godfrey). Of var. 

 cincta, one was found at Moy, 29th September 191 1, by Mr 

 Charles Oldham, to whom we are indebted for the actual 

 discovery of the species in most of its English localities.
