314 THE MOTHS OF THK HRTTTSH ISLES. 



The Double Line (Laicania {Eriopyga) turca). 



The sexes of this species are shown on Plate 150, Figs. 3 5,6$. 

 The general colour of the fore wings may be paler or darker than 

 in the specimens shown. Sometimes the central area enclosed 

 by the black cross lines is darker than the other parts of 

 the fore wings ; var. obsci/ra, Tutt, has the fore wings obscure 

 smoky grey, with a dull coppery tinge, much suffused with 

 dark scales ; markings indistinct. 



The caterpillar is pale brown freckled with darker ; a whitish 

 line along the middle of the back is edged on both sides with 

 blackish merging into black at the ring divisions ; a rather 

 wavy, but less distinct, whitish line on each side of the central 

 one edged alcove with blackish ; spiracles black ringed with 

 pale brown and set in a broad dark brown line below which 

 the colour is pinkish ; head shining pale brown, freckled with 

 darker on the cheeks. It feeds on cocksfoot and various other 

 grasses occurring in woodlands. August to May. The moth, 

 which inhabits woods and well-timbered parks, is out in June 

 and July. It is, perhaps, most frequent in the New Forest, 

 Hampshire, thence it is found more or less sparingly to Cornwall. 

 Sometimes not uncommon in Savernake Forest, Wiltshire, and 

 occurs in Berkshire, Buckinghamshire, Essex (Epping Forest, 

 etc.), Surrey (Richmond Park). Recorded from Cheshire and 

 from South Wales. In Scotland it is said to have been taken at 

 Newfield, Ayrshire. The only records from Ireland are Clon- 

 brock (i), and Merlin Park, Gal way (2). Abroad it ranges to 

 Amurland, China, Corea and Japan.
