Head pale saffron-yellow. Face and palpi silvery-white. Antenne 
yellowish, annulated with fuscous. Anterior wings pale saffron-yellow 
or very pale ochreous, with a basal line of the ground-colour, dark-mar- 
gined on both sides, terminating in the fold beyond the middle, and with

the first costal streak is dark-margined on both sides; between the

Head saflron-yellow. Face and palpi whitish. Antenne whitish, 
annulated with fuscous. Anterior wings saffron-yellow, with a straight 
basal line hardly paler than the ground-colour, dark-margined on both 
sides, terminating before the middle, and with four costal and three 
dorsal streaks yellowish-white; the first costal is dark-margined on 
both sides, the others only internally; the first dorsal streak is very 
long and curved, its apex reaching over the apex of the second dorsal spot, 
its apical half is dark-margined on both sides, the other spots are only 
dark-margined internally ; the third dorsal spot is very indistinct; the 
black apical spot is round. Posterior wings grey, with paler cilia. 
Very abundant in the south of England, appearing in May, 
August, and November. ‘The larva mines by preference the un-

Head reddish-ochreous. Face and palpi whitish. Antenne whitish, 
annulated with fuscous. Hinder tarsi whitish, spotted with dark fus- 
cous. Anterior wings reddish-ochreous, with a very slender unmargined 
whitish basal streak; in the middle are two very slender obliquely-placed 
opposite whitish streaks; both are preceded by a few dark scales, which 
are continued along the margins towards the base of the wing; beyond 
the streak are two (sometimes united) dark grey patches, one on the 
costa, the other beneath the apex of the dorsal streak, this is frequently 
continued towards the apex of the wing’; on the inner margin near the
