is a rather obscure darker brown line; bead ochreous. (W. 

 Buckler.) 



July to September, on knot grass {Polygonum avicidare), 

 rest-barrow, broom, whortleberry, dandelion, and other low- 

 growing plants. 



Pupa dark brown ; apparently not more fully described ; 

 subterranean. 



The moth hides itself during the day, most likely among 

 dead leaves and herbage upon the ground ; it is very 

 rarely captured during daylight, though a casual speci- 

 men may perhaps be found sitting on a wooden fence, 

 at dusk it flies vigorously and is strongly attracted by the 

 blossoms of Silenc infiata, Lilinm martaffon and Echmm 

 vulgare. It also comes, not rarely, to sugar. Twenty or 

 thirty years ago it was not uncommon in the outskirts of 

 London, visiting the flowers in gardens, but seems here to 

 have totally disappeared. Never very plentiful, but found 

 in moderate numbers throughout the southern and eastern 

 counties of England except Cornwall, where it has hitherto 

 been recorded in only one locality. North of a curved line 

 from Gloucestershire through Oxfordshire, Cambridgeshire 

 and Norfolk it seems very rare, hardly occurring in the 

 Midlands or western counties until we reach Yorkshire and 

 Lancashire, in both of which it is rare. The same is the case 

 in Wales, where it has been taken near Pembroke and at 

 Barmouth. Strangely enough it becomes more frequent in 

 Scotland, being recorded as rather common ab Crieff", and very 

 locally so in Perthshire and Ayrshire. Dr. Buchanan White 

 gives its localities as restricted to the districts of the Forth, 

 Clyde, Solway, and Tay. In Ireland it has been secured in 

 several succeeding years at Castle Bellingham, but I know 

 of no other locality for it iii that country. 



Abroad it is found throughout the temperate portions of 

 Northern Europe, Central Europe, North Italy, the Ural 

 Mountain districts, and the mountain regions of Central and
