NOTODONTIDyE. I2l 



the aid of a freshly reared female. In the daytime it sits on 

 oak trunks and probably branches, also occasionally on 

 palings near them, but is always scarce, the great majority of 

 the specimens in collections being reared, either from the Q^^, 

 from captured larvae, or from pup« dug from the foot of oak- 

 trees. Although so uncommon it is widely distributed, and 

 formerly might be taken, rarely, in the London suburbs ; still 

 found in Kent, Sussex, Surrey, Hants (more frequently in 

 the New Forest), Dorset, more commonly in South Devon — 

 rare in the north of the county — and in Cornwall. Not very 

 rare in Berks, Bucks, Oxfordshire, Norfolk, Suffolk and Essex. 

 Found rarely in Carmarthenshire, Gloucestershire, Worcester- 

 shire, Herefordshire, Sherwood Forest, Notts, North Stafford- 

 shire, and Yorkshire. There is a single record in 1851 at 

 Delamere Forest, Cheshire, and one specimen, taken in Cum- 

 berland, is in the collection of Mr. G. Dawson at Carlisle. 

 Excessively rare in Scotland, but Sir Thomas Moncrieff 

 obtained a larva at Moncrieff Hill, Perthshire, in 1874, which 

 he reared, and there are records in Clydesdale and Kirkcud- 

 brightshire. In Ireland it was recorded by Mr. E. Birchall, 

 but apparently without sufficient evidence. Abroad it is 

 widely distributed through Central Europe, Eastern Spain, 

 Italy, Corsica, South Sweden, Livonia, and Southern Russia.
