 SUBDIVISION 2. 



Anterior wings with one marginal and two submarginal cells ; 

 the discoidal cells obsolete. The scale of the peduncle usually 

 incrassate, generally much more so than in the first subdivision, 

 sometimes subquadrate, occasionally subnodose. (Sp. 96-121.) 



Note. We are acquainted with several species belonging to

 however, are also common to Europe, and are included in the 

 European series ; they are, F. viatica, lateralis, pubescens, opaca 

 and marginata.
