The moth is a lively little creature, fond of flying briskly 

 in the sunshine about the rough slopes of chalk hills, and 

 appearing especiall}^ attached to patches of wild thyme. 

 More local than the last species, and more restricted in its 

 distribution with us, hardly occurring away from the chalk, 

 though in favourite spots upon that soil it is tolerably 

 abundant. This is the case more particularly at Guildford, 

 Bos Hill, Mickleham and other chalk hills in Surrey; in 

 Kent, Sussex, Dorset and Wilts ; abundant on Durdham 

 Downs, Bristol ; and in smaller numbers it is found in 

 Devon, Somerset, Gloucestershire, Herefordshire, Oxfordshire, 

 Berks, Herts, Cambi'idgeshire, Essex, and near Tuddenham, 

 Suffolk. The only other locality in which I find it recorded 

 in Great Britain is in Westmoreland. In Ireland it was 

 found by the late Mr. E. Birchall in the County Galway. and 

 Mr. Kane records it from Derry. Abroad it seems to occur 

 all over the Continent of Europe, though only in dry sjiots ; 

 and is also found in Pontus and Bithynia.
