GROUPS AND FAMILIES 83 



sometimes rather elongate ; the costa nearly straight or 

 slightly arched, the hind margin never concave; the 

 ocellated blotch is wanting. In the most typical species 

 of this family, three nearly equidistant fascias are formed 

 by the outer edge of the basal patch, the central fascia, 

 and the prolonged subapical costal spot. 



This family is of small extent. We have only 13 

 British species, but some of these are exceedingly 

 numerous in individuals, and in a few the larvse seem 

 perfectly omnivorous, occurring on all sorts of plants. 



8. SERICORID^E. Imago with the anterior wings 

 rather broad ; the costa generally much rounded, the 

 tip sometimes pointed, the ocellated blotch not repre- 

 sented. In the most typical species, the central fascia 

 is broad, and its inner edge nearly straight. Larva 

 feeding between united leaves, or in roots. 



This family is of moderate extent. It comprises 22 

 British species, 



9. LOZOPEBID^E. Imago with the anterior wings of 

 variable length ; the costa generally regularly arched, 

 the hind margin often oblique ; the ocelloid blotch not 

 represented (excepting in the solitary instance of the 

 beautiful Culosetia nigromacnlana) . In many of the 

 typical species the ground-colour of the anterior wings 

 is some shade of yellow, and the central fascia, starting 

 from the inner margin, is parallel to the hind margin. 

 Larva generally feeding on seeds. 



This family is extensive, and comprises many beau- 

 tiful species. We have no less than 45 British species. 



Between the TOUTRICINA and the TINEINA has been 

 placed the family TORTRICODIDJE (which consists of only 

 a single species, Tortricodes hyemana). Imago with the 

 anterior wings more than twice as long as wide ; the
