TRIFID.-E. 229 



The moth hides by day among herbage and leaves on the 

 ground ; at dusk it visits the sallow-bloom, and settles down 

 upon it most contentedly ; it is also said to frequent the 

 blossoms of blackthorn and plum, and comes occasionally to 

 light. Formerly it was common in the London district ; but 

 has become there much more scarce ; still moderately common 

 throughout the southern, eastern, and most of the western 

 counties of England, though scarce in Devon and Cornwall, 

 also found more locally in the Midland Counties ; rather 

 common in Yorkshire ; less so in Cheshire and Lancashire, 

 and existing in Durham, Northumberland and Cumberland. 

 In South Wales it has been met with in Carmarthenshire and 

 Pembrokeshire, but I find no record in North Wales. Not 

 scarce in the South of Scotland, but rare in Lanarkshire and 

 Stirlingshire, common in Arran and also in Aberdeenshire ; 

 in Perthshire it is said to be most frequent upon the hills at 

 above 600 feet ; found also in Moray and in the Orkneys. 

 In Ireland it appears to be most common in the Northern 

 Counties — Derry, Donegal, Antrim, and Down ; also found 

 in Wicklow, Kerry, Galway, Sligo, Cavan, Tyrone, and at 

 Enniskillen. Abroad its range is wide — the temperate regions 

 of Northern Europe, Central Europe, Northern Italy, Gibraltar, 

 Northern Turkey, Southern Russia, Tartary, and the mountain 

 regions of Central Asia.
