1 1 8 LEPIDOP TERA . 



Argyleshire, Perthshire, Inverness-shire and Moray, even to 

 a height, where the fir woods extend up the hills, of 500 feet 

 above sea level. Probably very local in Wales, since it seems 

 only to be recorded in Glamorganshire. In Ireland it seems 

 probable that its complete extinction and re-introduction 

 may have taken place within a comparatively recent period. 

 Mr. Kane points out that the indigenous pine became extinct 

 about the time of Queen Elizabeth, and that, according to 

 the Cyljclc Hibcrnica.^ " there is no satisfactory proof of the 

 survival of native Irish Finns sylvestris." "The forests of 

 Wicklow, from which some nine hundred years ago the King 

 of Leinster cut a tribute of fir masts for Brian Boru, survives 

 only in oak and other trees which spring again from stools; and 

 in the free-seeding birch." He thinks that it must have been 

 introduced during the last few hundred years, when settlers 

 began to import and plant conifers. If this is so, the insect 

 has again become well distributed, since it has been obtained 

 in Dublin County, Wicklow, Waterford, Cork, Kerry, Galway, 

 Sligo, Westmeath, King's County, Louth, Fermanagh, Tyrone, 

 Armagh, Down, Antrim, Donegal, and Derry. Abroad it has 

 an extensive range through Central Europe ; all but the 

 coldest portions of Northern Europe, including part of Lap- 

 land ; Northern Italy, the Ural Mountain district, Siberia, 

 and the mountainous regions of Central Asia.
