GRACILARIA. 199 
Head and face whitish. Palpi white, the end of the second joint 
and a ring before the apex of the terminal joint dark fuscous. Antenne 
fuscous. Anterior wings greyish-fuscous or ochreous, with five white 
streaks from the costa, the first four oblique and nearly at equal dis- 
tances, the fifth in the extreme apex running out into the hinder mar- 
gin; along the base of the inner margin is a white blotch, which almost 
meets the first costal streak, and below the apex of the second costal 
streak is a small white spot on the middle of the inner margin ; cilia of 
the apex whitish, with a dark outer line, of the inner margin grey. 
Posterior wings grey, with paler cilia. 
Common at Dartford Heath, at the end of July, among Arte- 
misia vulgaris. The larva mines the leaves of that plant, not 
contorting them, but giving them an inflated appearance, at the 
end of June and beginning of July, and again in the autumn. A 
brood of the perfect insect probably appears in May.

Head and face brown. Palpi brown, the base and tip of the termi- 
nal joint paler. Antenne brown. Anterior wings shining brown, with 
two whitish spots on the inner margin (one near the base and one in 
the middle), and three on the costa (the first oblique before the middle, 
the second curved posteriorly beyond the middle, the third very indis- 
tinct. just before the apex); these spots are rarely distinct, and at times 
hardly distinguishable except by their dark margins ; cilia brown. Pos- 
terior wings grey, with paler cilia. 
Appears in September and October, among Polygonum Hydro- 
piper. Taken by Mr. Weaver in Scotland, and by Mr. Boyd in 
the New Forest. The larva feeds in August and September on 
the leaves of the Polygonum Hydropiper ; it cuts a strip from the 
side of a leaf, and rolls it up, taking care not to separate it from 
the leaf; this rolled-up portion of leaf is generally placed perpen- 
dicularly to the lower surface of the leaf; the larva feeds within 
it, and when its provisions fall short, proceeds to treat another 
leaf in a similar manner; when full-fed it spins a fine white co- 
coon within the rolled piece of leaf. (The only larva known to 
feed in a similar manner is that mentioned by Réaumur as feeding 
in September on the leaves of the sorrel, but this has not been 
met with by any subsequent writer, and the species which it pro- 
duces is unknown to us.)
