Il6 LÉPIDOPTÉROLOGIE COMPARÉE 



several entomologists to vvhom it is f^/vcr cognita ; but neither they, 

 nor I hâve ever corne across the species hère. 



It has been recorded, also, from Ashdown Forest, Sussex, in 

 the S. E., a most unhkely locality. 



The terminal line of tiphon in Wales and England, therefore, 

 may be drawn through mid-Merioneth, North Shropshire, North 

 Staff ordshire and by the eastern boundary of Cheshire ail along 

 the Southern limits of Yorkshire, with an unoccupied interval 

 roughly represented by the North Derbyshire frontiers, to the 

 Humber estuary. 



E) Ireland. 



So little is still known, entomologically of Ireland, that I 

 approach this last section of my remarks on the distribution of 

 Cœnonympha tiphon in Ireland with considérable hésitation; nor 

 can I prétend to throw much light on the subject. For it was 

 not until many years after the British lepidoptera had been noted, 

 and recorded, that naturalists across St. George's Channel turned 

 their attention to their own most interesting butterflies and moths. 

 We owe it to the late Mr. Edwin Birchall that a preliminary 

 catalogue was collected and published in the pages of the 

 Eiitojuologist's Monthly Magazine (Vol. III, 1867). Later in 

 the Entomologist (Vols. XXVI-XXXIV, 1 893-1901) Mr. W. F. de 

 Vismes Kane expanded and amplified his predecessor's notes and 

 observations in his own Catalogue of the Xepidoptera of Ireland. 



DESCRIPTION 



In Ireland the Middle Form extends practically from one end 

 of the country to the other in the localities where tiphon is known 

 to occur, that is to say from the 55th parallel to the 52nd, thus 

 somewhat further south than in Britain ; while in the extrême 

 south west it reaches down still further to Bantry Bay in the 

 County of Cork, and the mountains of Kerry. Of the form of
