General Characters. — Head usuall}- with dense loosel}- raised scales, seldom smooth; 

 ocelli present; tongue usuall}- well-developed, seldom absent. Antennae one-third to two-thirds of 

 forewings, in (f usually ciliated, seldom pectinated. Labial palpi moderate or long, porrected or 

 subascending, second joint with dense projecting or appressed scales, usually more or less triangular, 

 terminal joint short or moderate, cylindrical, obtuse. Maxillary palpi obsolete. Thorax often crested. 

 Posterior tibise clothed with dense rather rough scales. Eorewings subtriangular; ib normally with 

 strong basal furcation. cell moderate, sometimes narrowed, parting-veins sometimes strongly developed, 



1 from before 3/4 of lovver margiii of cell, widely remote from 3, 4 and 5 more or less approximated," 

 6 separate, 7-9 variously arranged, 11 from about middle of cell. Hindwings subtrapezoidal, usually 

 broader than forewings, rarely narrower, usually without basal pecten of hairs on lower margin of cell 

 but sometimes with this developed, ciha usually short; ib shortly furcate at base, ic well-developed, 



2 remote from angle, 3-5 variously arranged. 6 and 7 normally approximated towards base or stalked, 

 rarely remote. 



Larva with prolegs on segments 7-10 and i3, usually feeding in rolled or spun leaves, rarely in 

 fruits, stems, or galls, often ver}' polyphagous. 



Pupa with segments 8-1 1 free. in (j* 12 also; protruded from cocotm in emergence. 



This undoubtedly natural family is separated from the Eiicosmidae primarily by the absence of 

 the basal pecten of hindwings, but this is not an absolute character, as several genera of Tortncidae 

 possess the pecten ; no genus of Eucosmidae is without it. Thnse genera of Tortricidae which are really 

 nearest to the Eucosmidae are however all without it, and its occasional later reappearance as a rever- 

 sional character does not in my judgment destro}- the natural distinction, especially as in some cases it 

 is but slightly developed; in all doubtful cases the test is available and satisfactory. A secondary but 

 less easily appreciable distinction is afforded by the triangular scaling of the palpi; and the greater 

 diversification of the neuration is a contributory point. Apart from the Eucosmidae, the wide separation
