The motli sits during the tlay on the trunk.s of ash-trees<. 

 or occasionally on apple or elm trunks, and is there very 

 conspicuous, its deep black spots distinguishing it at once 

 from all other species : indeed, it is of a particularly pretty 

 bright appearance. It flies in the evening, and conies

 a local species, but found in the New Forest, Hants, and in 

 iSurrey, Sussex, Dorset, Devon, Cornwall. Somerset, Wilts. 

 ti loucestershire, Herts, Norfolk, Herefordshire, Cheshire, 

 Tjancashire, Yorkshire, and Westmoreland ; but I find no

 Kerry. Abroad it inhabits most parts of Central Europe, 

 Denmark, Spain, and Sardinia.
