232 LEPIDOPTERA. 



white costal streak at a decided angle ; beyond are three 

 more pairs of white costal streaks, the first extending to the 

 corner of the ocellus and thence to the dorsal margin, on its 

 way bending decidedly imvarcl from the anal angle ; ocellus 

 edged on both sides with silvery white, and filled with short 

 black lines ; cilia brown-black. Hind wings blackish brown 

 with a reddish flush ; cilia tipjDed with white. Female 

 similar. 



Underside of the fore wings leaden brown, with distinct 

 white costal dots. Hind wings leaden white. 



On the wing from the end of May till July. 



Larva dull yellowish white ; head pale brown ; spots im- 

 perceptible. (J. Sang.) 



On Scotch fir (Finns sijlvestrig), feeding in the bark — but 

 Mr. Sang furnishes no information as to the time of feeding. 

 Mr. W. Reid states that he has reared a number of specimens 

 from larvae feeding in fir Ijuds. 



The moth sits during the day, or at any rate the early 

 portion thereof, in a fir tree, and if beaten or shaken out 

 buzzes on the sheltered side of the tree and returns to its 

 resting-place as soon as possible ; on fine daj's flies in the 

 afternoon about the tops of the same trees ; but if there is 

 a little breeze flies more on the sheltered side and lower 

 down. Just before sunset it loves to fly very swiftly around 

 young trees. In the north it may also often be found on 

 the trunks of the older trees. Rather local, but to be found 

 sparingly in fir woods in Kent, Surrey, Hants, Dorset, 

 ' Norfolk, Suffolk, Gloucestershire, Herefordshire, and 

 Leicestershire ; more frequently in the northern counties 

 from Cheshire and Yorkshire ; in Scotland widely dis- 

 tributed and common ; but I have no records for Wales or 

 Ireland. Abroad it is common in Central Europe, and is 

 found in Piedmont, Portugal, and Norway.
