with three diirk fuscous streaks, oue towards tl)c costa, one to the ex- 

 treme apex, and one originating at the same point, drooping. Poste- 

 rior wings white, with white cilia. 



Abundant in May and August. The larva mines the leaves of 

 the laburinim in autumn and July, making large greenisli-white 

 blotcheSj which, when they have been made some time, become 

 almost white ; the larva quits tlie leaf when full-fed, and spins its 

 white cocoon in some convenient nook.

S '^"'~ Head and face leaden-grey. Antcmifc black, basal joint leaden- 



grey. Anterior wings leaden-grey ; from the costa beyond the middle 

 is a brownish streak, which reaches obliquely across the wing ; beyond 

 it are two short white streaks on the costa, separated by a copper- 

 coloured ])ortion, which reaches more than half across the wing ; at the 

 anal angle is a large black spot with a violet pupil ; cilia whitish, with 

 four radiating dark lines, two towards the costa, one continued to the 

 extreme apex, the fourth rather drooping. Posterior wings pale leaden- 

 grey, with grey cilia. 



An abundant species in many localities in June and July. The 

 larva mines the leaves of the hawthorn, apple, and pear, causing 

 large flat dark brown blotches, and frequently to such an extent 

 as to cause the hedges to appear of a brownish-green colour; 

 when full-fed, in August or September, it quits the leaf, and s[)ins 

 its line white cocoon, and after changing to pupa, it ejects the 

 shrivelled larva-skin through a slit in the cocoon left for that 

 purpose. 



It is difficult to conceive a more beautiful insect than this ! 

 Goeze/s rhapsodies at the sight of this (or a closely-allied species), 

 in the fifth volume of the ' Naturforsclier/ do not appear at all 

 exaggerated, and are well worth perusal.
