Head reddish-ochreous. Face pale ochreous. Palpi pale ochreous ; 
the terminal joint reddish-ochreous. Antenne fuscous, annulated with 
whitish. Anterior wings reddish-ochreous, irregularly varied with darker 
markings, in which a ¢vuncate costal triangle, hardly paler than the 
ground-colour, may generally be traced; it has sometimes a dark fus- 
cous spot on each side above the fold; cilia of the hinder margin red- 
dish-ochreous, of the inner margin grey. Posterior wings grey, with 
paler cilia. 
This extremely variable species is not scarce in many localities; 
taken in plenty by Mr. Cooke, of Warrington, in June. Mr. 
Shield found the larvee in rolled-up alder-leaves near Dublin, last 
August. According to Lienig the larva also feeds in May.
