A very large genus, quite cosmopolitan, but probably attaining 



its greatest development in Europe. Owing to their small size 

 and similarity of appearance the species present considerable 

 difficulty, and have been so 

 much neglected that their dis- 

 tribution is hardly known ex- 

 cept in England and Germany, 

 and even there very imperfectly. 

 Most of the species can seldom 

 be obtained except by rearing 

 the larvae, but some fly freely \;5 

 in the sunshine. Imago with 

 forewings lanceolate. Larva 

 without developed legs or pro- 

 legs, but with pairs of rudi- 

 mentary ventral processes on 

 .3, 4, and 0-1 1, or rarely wholly apodal, 

 usually outside the mine.
