1 66 LEPIDOPTERA. 



furrowed ; limb-covers smooth but well marked ; wing-cases^ 

 smooth and only faintly furrowed in the most superficial 

 manner ; these portions very glossy pitchy-brown ; dorsal 

 and abdominal segments also glossy, red-brown, pitted with 

 small punctures except upon the smooth hind band ; anal 

 segment thickened and ridged, darker in colour; cremaster 

 flattened, broad, and tapering off' to a pair of strong bristles, 

 hooked in opposite directions, and surrounded by minute 

 curled bristles. In a slight open cocoon among the lichen 

 on which the larva fed. 



The moth sits during the day on lichen-covered trunks of 

 trees, and even more frequently on the branches when these 

 latter are shaggy with lichens ; from these it is easily dis- 

 lodged by a blow of a stick, but very commonly it flutters 

 down to the ground like a falling bit of leaf or bark, and if 

 noticed tries to struggle under the fallen leaves ; but some- 

 times, especially if the weather is hot. it will fly to another 

 tree for concealment. It flies naturally at late dusk, and in 

 the night, and will come to light. Almost confined to woods 

 and hedges so dense, or localities so moist, that lichens will 

 grow on the branches or trunks of the trees. In such suit- 

 able places common throughout the Southern, Eastern and 

 Western Counties to the Scilly Isles ; very rare in the Mid- 

 lands ; recorded once only in Derbyshire ; also scarce in 

 Cheshire, Lancashire, Yorkshire, Westmorland and Cumber- 

 land. Probably to be found in woods throughout Wales, 

 since I have found it in Pembrokeshire. In Scotland it occurs 

 in the Edinburgh district. Roxburghshire, Ayrshire, Lanark, 

 and Wigtownshire, though not commonly; more rarel}' in 

 Aberdeenshire, Forfarsbire and Ross. Dr. Buchanan White 

 says "to Clyde and Moray." In Ireland Mr. Kane records 

 its wide distribution — Dublin County with the Isle of Lambay, 

 Waterford, Cork, Kerry, Galway, Westmeath, King's County, 

 Sligo, Fermanagh, Monaghan, Tyrone, Armagh, Down, 

 Donegal and Londonderry. Abroad its range extends over
