 inner and outer lines dark brown, fine and faint; the inner bent on each fold, vertical in the main; the lis - 

 outer widely excurved and irregularly erenulate beyond cell, insinuate on submedian f old ; subterminal line strong- 

 er, oblique from before apex and straight, outwardly edged by whitish; a conspicuous slender brown lunule 

 at end of cell; terminal line dark, edged with a bright white line at base of fringe; hindwing with outer 

 and subterminal lines marked on inner marginal half of wing. Larva reddish yellow; the segmental incisions 

 paler: dorsal line redbrown; three subdorsal, irregularly erenulate or hidden in blotches, finer, parallel, pale 

 reddish lines; beneath the black spiracles a double irregularly erenulate lateral line; feeding on rotten leaves 

 and all kinds of low plants. Occurs throughout Europe (not in Britain); also in Armenia, the Altai Mts.,

 line better marked, bordered with dark on both sides; the outer line more dentate; the cell lunule ocellate; lis '
