SHARP-ANGLED CARPET. 199 



the outer marginal border of all the wings is not infrequently 

 enlarged, in some cases so much so that the borders are sepa- 

 rated into two parts, and also reduced in width. 



The caterpillar is grey brown, ochreous brown between the 

 rings and on the underside ; a dark line along the back, and a 

 dark-edged, pale line on each side ; a black dot on each ring at 

 the junction of the dark upper and pale lower areas ; head, 

 grey-brown, with blackish freckles. It feeds, in July and 

 August, on bedstraw, preferring the heath kind {Galium saxatile)^ 

 but will eat the large hedge kind {G. inolhigd). 



The moth is out in June, or from late May, and in some parts 

 specimens are seen in August. Its haunts are moors and 

 upland heaths, and its British distribution extends from Dart- 

 moor and Exmoor, in Devon, through Western England and 

 Wales to Westmorland. It appears to be very local in Somer- 

 set, Gloucester, Hereford, Shropshire, and Cheshire ; from 

 Staffordshire and Derbyshire northwards, and through Scotland, 

 it becomes more plentiful ; and has been recorded from the 

 Shetlands. In Ireland it is local, but common where it occurs. 



Sharp-angled Carpet {Xanthorhoe {Etipkyia) tmangulata). 



This species (Plate 82, Figs, i, 2) may be recognized by the 

 distinctly angled outer edge of the blackish central band, which 

 is thrown into strong relief by the usually broad white stripe 

 following it. Wilkes, who figured the moth in 1742, called it 

 the " White Stripe." By some authors the species is referred 

 to ainniculata, Hiibner. 



The caterpillar is pale whity brown, with a slightly darker 

 but indistinct line along the centre of the back, and a black 

 spot on the middle rings ; a pale line on the sides is edged 

 with dark grey ; head, brown, marked with black. It feeds, in 

 July and early August, on chickweed {Sicllafia media).
