 limestone hills in Worcestershire, about 1857 or 1858, and 

 in 1859 was recorded, as British, under the name of Ino 

 tenuicornis. In addition to the Lewes locality already 

 mentioned, it has since been found in plenty in other places 

 on the slopes of the chalk downs of Sussex and Kent, near 

 Brighton, Canterbury, Shorncliffe, Abbotts Wood, &c. ; in 

 Oxfordshire in glades of beech-woods on the hills sides ; 

 on the slopes of the Cots wolds in Gloucestershire as well 

 as Worcestershire ; near Barmouth, North Wales ; on the 

 Malvern Hills ; at Grange and Silverdale in Lancashire ; near 

 Beverley in Yorkshire ; at Bakewell, Derbyshire ; and near 

 Hartlepool, as well as at various places along the Durham

 parts of Spain ; in Switzerland ; in various localities in 

 Germany; Vienna and other parts of Austria, including 

 Carinthia ; and in Asia Minor.
