opposite to it on the inner margin is @ small silvery streak, terminating 
in a metallic streak, which runs to the apex of the wings. Posterior 
wings grey, with paler cilia. 
Appears in May and August, but rarely met with in the perfect 
state. The larva is excessively abundant, mining the under side 
of the leaves of the elm in autumn and in July; it forms a bluish- 
green cocoon.

Head reddish-ochreous. Face and palpi white. Antennz whitish, 
annulated with fuscous, the tip white. Anterior wings reddish-ochre- 
ous, inclining to brownish; in the middle of the base is a small unmar- 
gined yellowish spot, then follow three whitish fasciee, all with dark 
margins internally, gradually shading off to the ground-colour, the two 
first are nearly straight, the third is angulated, and from its angle a 
whitish streak runs into the costa at the apew ; beneath this streak lie 
the apical black scales. Posterior wings grey, with paler cilia. 
Not uncommon in May and August. It has been bred by Mr. 
Grant and Mr. Dunning, from larvae found in elm-leaves in au- 
tumn, and not distinguished at the time from the larvee of Schre- 
berella. TI believe I have bred it both from elm and hawthorn!

Head reddish-ochreous. Face and palpi whitish. Antenne whitish, 
annulated with fuscous. Anterior wings veddish-ochreous, with three 
slender whitish fascie, bordered with black towards the base of the 
wing, most broadly on the costa; the first fascia is only slightly curved, 
the second is angulated above the middle, the third is angulated and 
frequently interrupted in the middle, whence some black scales are 
continued to the anal angle; on the costa before the apex is a short 
whitish streak, preceded by a few black scales; below it are the black 
scales of the apex of the wing. Posterior wings grey, with paler cilia, 
Common generally, but very abundant in Devonshire ; appears 
in May, August, and November. ‘he larva feeds in April, J uly, 
and autumn, in the under side of the leaves of the honeysuckle ; 
its mine is rather small, and it twists the leaf at a right angle.
