518 TORTRICINA 



2. TORTRICIDAE. 



Forewings : 2 from before f of lower margin of cell, 9 

 separate. Hindwings : lower median vein not hairy towards 

 base (except Sparganothis). Uncus developed. 



This large family is nearly equally plentiful everywhere. 

 The species are of rather small size. Forewings with central 

 fascia oblique, running from about middle of costa to dorsum 

 before tornus ; ocellus absent ; costal patch usually defined. 



Two exotic genera are introduced (in brackets) into the 

 diagram to explain the phylogeny.
