3/6 LEPIDOPTERA. 



ter by which it may readily be identified. (Adapted from 

 Buckler.) 



March till June on the seeds of wych-elm {Ulmus mon- 

 tana), feeding in company with the larva of Ortlwsia fcrru- 

 ginea, which it much resembles. In the egg-state through 

 the winter. 



Pupa apparently undescribed and almost unnoticed. 



The moth is rarely, if ever, seen in the daytime ; at dusk 

 it will come to sugar, though not freely, but more commonly 

 from half-past nine at night onwards ; and it has been taken 

 at light. A very local species, but apparently extending its 

 range within the last few years. The first specimens noticed 

 in this country seem to have been taken near Doncaster, 

 Yorkshire, about 18'12 or 1843, and it has repeatedly occurred 

 in moderate numbers in that neighbourhood. It is not very 

 uncommon in Norfolk and Suffolk, and in the Cambridge fen 

 district, and is taken occasionally in Essex, Herts, Middlesex, 

 Oxfordshire, and Berks. In Surrey it does not seem to 

 have been noticed until 1895, when it suddenly appeared at 

 Kingston-on-Thames ; in Sussex its principal locality seems 

 to be about Brighton, where its yellower forms are most 

 frequent. Very rare in Somerset, and found in Hereford- 

 shire, Leicestershire, Derbyshire, Salop, Staffordshire, War- 

 wickshire, and, as already stated, in South Yorkshire ; very 

 rare in Cheshire and Lancashire, and apparently not noticed 

 farther north. There is a single record in North Wales — 

 in Flintshire — but I know of none in Scotland or Ireland. 

 Abroad its range seems to be confused with that of the next 

 species, but it is widely distributed through Central Europe, 

 and is known to occur in Kashmir and the mountain regions 

 of India, so may safely be credited with a more extended 

 range,
