with three dark fuscous streaks, one towards the 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 laburnum in autumn and July, making large greenish-white 
blotches, which, when they have been made some time, become 
almost white; the larva quits the leaf when full-fed, and spins its 
white cocoon in some convenient nook.

Head and face leaden-grey. Antenne 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 portion, 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 spins 
its fine 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! 
Goéze’s rhapsodies at the sight of this (or a closely-allied species), 
in the fifth volume of the ‘Naturforscher,’ do not appear at all 
exaggerated, and are well worth perusal.
