40 LEPIDOPTERA. 



Gardens: very common in the Eastern Counties and through- 

 out the South of England to Dorset and Somerset, also to be 

 found elsewhere to Yorkshire, Durham, and Cumberland, 

 where Scotch fir-trees are plentiful ; but I can find no record 

 for Wales. Widely distributed in Scotland to Perthshire 

 and Moray ; and in Ireland noticed in Galvvay, Down, and 

 Armagh. Abroad its range extends through Central and 

 Northeim Europe and North Italy; and it is reported to exist 

 in North America in Oregon.

Larva apparently hardly described. Ratzeburg says that 

 it is very similar in form and colour to that of B,. huoliana, 

 and that it lives in the same manner in the buds of Scotch 

 fir ; also that it is full-fed from June to August, and remains 

 eiglit months in tltc inqyo state! Sorhagen says that it feeds 

 in May and June in the buds, later in the young shoots of 

 the taller fir-trees ; attaining the pupa state in the hollowed 

 shoot. 



This is a rare species in these Islands and very little
