TORTRICINA. 53 



ceeds twice their width; very varied in their colouring, and 

 often bearing in the inner, or dorsal margin, a pale blotch, 

 mostly white, or whitish, and differing in size and shape. Poste- 

 rior wings usually very broad, frequently broader than the ante- 

 rior pair. 



As in the preceding family, the larvae for the most part feed 

 in folded, rolled, or united leaves. Some of the genera (Ha- 

 lonota, Dicrorampha) are chiefly internal feeders, passing their 

 preparatory states in the roots, stems, &c. of herbaceous plants. 



There are fifteen genera in this family, which may be arranged 

 as in the following Table : 



A. Anterior wings with the fold on the costa 

 not closely appressed to the surface. 



a. Palpi with the middle joint three times 



the length of the apical 1. LOZOTJENIA. 



a a. Palpi with the middle joint more than 

 three, but less than four times, the length 

 of the apical 3. PTYCHOLOMA. 



B. Anterior wings with the fold on the costa 

 closely appressed to the surface. 



a. With the fold broad and rounded . . 2. DITTJLA. 

 a a. With the fold narrow.
