GRACILAIUA. 11»1^» 



Head and face whitish. Palpi white, the ciul of the second joint 

 and a ring before the apex of the terminal joint dark fuscous. Antcnuce 

 fuscous. Anterior wing-s (/re^jiuli -fuscous or ochreoiis, with five icliilc 

 streaks from the costa, the tirst four oblique and nearly at equal dis- 

 tances, the lifth in the extreme apex nuuiiiii^- out into the hincku' mar- 

 gin ; along the base of the -inner margin is a white blotch, which almost 

 meets the tirst costal streak, and below the apex of the second costal 

 streak is a small white spot on the middle of tlic 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 cud of »lulv-, among AHe- 

 misia vulijaris. The larva mines the leaves of that plant, not 

 contorting them, but giving them an iniiated 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. Antenna3 brown. Anterior wings shining brown, with 

 two u-hUifih spots on the iimer 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 vei-y indis- 

 tinct just before the apex) ; IJiese sjwls are rnrehj distinct, and at times 

 hardlij dlstlufjulshaljle except by their dark marcjlns ; cilia brown. Pos- 

 terior wings grey, with paler cilia. 



Appears in September and October, among Fohigonum llijdro- 

 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 Pob/fjonnm llijdropvper ; 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 line white co- 

 coon within the rolled piece of leaf. (The only larva known to 

 feed in a similar manner is that mentioned by lleaumur 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.)
