328 LEPIDOPTERA. 



Like its congeners, placed under a leaf upon a thin silken 

 carpet, to which the bristles of the cremaster are tightly 

 fixed, also supported by a silken thread across the back. 



The moth sits during the day under leaves in birch bushes or 

 the lower branches of birch trees, and is readily disturbed by 

 the beating stick, when it flies vigorously away to a similar 

 shelter. Its natural flight is at dusk, and it has been known 

 to come to the blossoms of heather in the autumn ; and also 

 to be occasionally attracted by light. It formerly occurred 

 in the South London suburbs, but seems to have been driven 

 further out. Its usual haunts are ojjen woods and woody 

 heaths where birch bushes are plentiful, and in such situa- 

 tions it is common in the Southern Counties of Eno-land 

 and more locally so in the Eastern and Western Counties. 

 In the Midland districts it is usually absent, but has been 

 found in Sherwood Forest, Notts, in the ikirut Wood, 

 Staifordshire, and in Warwickshire. Further north it is 

 very local in ^'orkshire and Cumberland, and there is one 

 doubtful record in Northumberland. In Scotland it exists 

 in the district of the Solway, in Ayrshire, Argyleshire, 

 Kincardineshire. Aberdeenshire, Moray, and Eoss-sliire, and 

 is rather frequent at Moncriefte Hill and elsewhere in Perth- 

 shire. In AVales I find but one record— in Glamorganshire— 

 though it surely cannot be absent elsewhere. In Ireland it 

 IS local, but sometimes common in Wicklow, Kerry, Galway, 

 Westmeath, and Tyrone. Abroad found throughout Central 

 lilurope, the temperate portions of Northern Europe, 

 Northern Italy, Southern and Eastern Russia, and Eastern 

 Siberia.
