SERICORIDJE—HALONOTA. 139 



easy to see from the darkness of both fore and hind wings. 

 It is rather an obscure species, and often mistaken for P. 

 scmifuscana or P. solandriana, but may be known by its 

 rather uniform soft, but dull, brown colour and its somewhat 

 grey-brown hind wings. Usually considered a rather local 

 species, but found in Kent, Surrey, Sussex, Hants, Berks, 

 Dorset, Devon, Gloucestershire, Herefordshire, Essex, Cambs, 

 Hunts, Norfolk, Derbyshire, Cheshire, Lancashire, Yorkshire, 

 and Durham ; also in Scotland in the Edinburgh district, 

 the Clyde Valley with Dumbartonshire, Perthshire, and 

 Aberdeenshire ; but I have no record for Wales or Ireland. 

 Abroad it is found in most parts of Central Europe, Piedmont, 

 Sweden, Finland, and Western Russia.
