256 LEPIDOPTERA. 



dusted witli yellow ; cilia smoky browu, with a whitish basal 

 line. Hind wings light smoky brown, with whiter cilia, 

 Female similar, but the costa not folded. 



Underside of the fore wings pale lead colour ; hind wings 

 leaden w^hite. 



On the wing in July and August. 



Larva short and thick, pale yellow, the internal dorsal 

 vessel visible at the tenth segment ; head and dorsal plate 

 brown ; anal plate hardly visible. 



May and June on Chrysanthemum Uncantliemum (ox-eye 

 daisy), boring into the growing shoots just below the buds, 

 causing I he shoot to become thickened and distorted; feeding 

 on the pith and sometimes eating out a bud. 



Pupa brown ; spun up within the larval burrow. 



The moth seems to prefer flying about scattered plants of 

 Chrysanthemum leiicanthemum, growing in pastures — very 

 often hill pastures — in the afternoon sunshine. It is not 

 very generally common, yet has a wider distribution than 

 most of its allies ; found in Kent, Surrey, Sussex, the Isle of 

 Wight, Dorset, Wilts, Berks, Essex, Suffolk, Norfolk, Here- 

 fordshire, Lancashire, Yorkshire, Westmoreland and Dur- 

 ham ; in Wales I found it in Pembrokeshire ; and in Scotland 

 it is known in the Edinburgh district and Perthshire, and has 

 been found in Shetland ; but I know of no record in Ireland. 

 Abroad it seems to be but little known, but has been taken 

 in South-west Germany and in Iceland.
