414 LEI'inoPTERA. 



black lines ; discal spot white ; hind margin narrowlj^ edged 

 with black; cilia shining whitish-grey. Hind wings ample, 

 the apex a little angulated, and hind margin flatly rounded ; 

 shining smoky white ; cilia whiter. Female similar, but with 

 the antennfe threadlike. 



Underside nq:?^ glossy ; fore wings pale smoky grey ; hind 

 wings white. Body and legs whitish-brown. 



On the wing from the end of June till August. 



Larva five-eighths of an inch in length, active, cylindrical 

 but tapering slightly behind ; dull grey or dull greyish- 

 white, with the narrow dorsal, and broad subdorsal lines 

 dark smoky grey ; spots similar, with abundant fine hairs ; 

 intestinal canal dark green, giving a greenish tinge to the 

 body ; head shining brownish-black ; thoracic plate dark 

 brown, usually grey towards its anterior edge ; anal plate, 

 ventral surface and legs horn-colour. (E. A. Atmore.) 



August and September to April and May ; in the previous 

 years young shoots of Pinus si/lccstris (Scotch fir), eating out 

 the pith and partially filling the passage with excrement, 

 but having a round hole for exit at the end of the tunnel ; 

 occasionalljr feeding in the young green shoots, or even 

 hollowing out a very young cone. 



This description does not agree with some of those 

 previously given, but these others I am satisfied refer to the 

 next species. Mr. Atmore has devoted much time, in 

 several seasons, to working out this larva, with results 

 which to me appear fully satisfactory. Moreover, I have 

 myself reared this species from larva3 exactly such as he 

 describes. It has also been reared by ^Ir. 11. Adkin from 

 the pine shoots on which were the nodules of Retinia 

 resinella. 



Pupa apparently undescribed. It is said to be found in 

 rotten firwood, dead fir stuni])s. and under moss on the 

 arround beneath.
