 a stone or root. 



The luoth sits hy day upon the trunk of a tree, esi)ecial!y 

 a birch-tree, or on a stem or branch of a large sallow, or any 

 neighbouring post, and is then quite conspicuously visible : 

 its shape is also noticeably triangular, the fore wings being 

 lirought down quite over the hind and concealing the abdo- 

 men, all pressed closely tu the tree. Here, unless the 

 weather is quite warm, it is (juiet or even sluggish, and may 

 be boxed off its re.-,ting -place, but if the sun is hot it will fly 

 wildly to a short distance, to settle on the ground or among 

 the thickest bushes. At dusk it Hies naturally around 

 sallows and birches, but keeps rather high in the air, and is 

 not commonly captured at that time. Occasionally it will 

 resort to the sallow-bloom, to feed along with the Nodvn, 

 and later at night will come to a strong light. Trincipally 

 attached to woods, and wooded heaths, though a specimen 

 may now and then be seen on a wayside birch or sallow in 

 wooded districts. lu micIi suitable situations to be found 

 tliroughout England, and in most parts of Ireland. In 

 Wales the only records that I find are from the south, and in 

 Pembrokeshire it is certainly scarce, yet there is little doubt 

 of its jiresence throughout the I'rincipality. In Scotland it 

 is found in the southern districts, in I5erwickshire, lienfrew, 

 and elsewhere : also in South Argyle ; uncommonly in 

 Aberdeenshire, KiiicardiiH'sliiie, and Inverness : commonly on 

 ^loncrieffe Hill and elsrwiieiv in Perthshire: and ai)nndantly 

 in Sutiierlandshire. Abroad throughout ("entral Kurope, 

 the temperati- portions of Northern Kurope. Northern Italy, 

 the Ural I\lountain ilistrict, Kastern Siberia, and Tartary.
