SYNOPSIS OF THE BRITISH PHRYGANID^. 



85 



this is more or less covered with brown punctures; 

 posterior wings hyaline, with an indistinct yellow 

 pterostigma. 



The markings of the anterior wings vary very con- 

 siderably, according as the brown streak is more or 

 less sharply and broadly marked, interrupted, or even 

 completely broken up into a series of small dots. 

 The coloration of the portion of the wing behind the 

 streak is also very variable ; usually there is a triau- 

 gular brown dash on the apical margin, and the pos- 

 terior margin is spotless ; but the former may also be 

 replaced by numerous points, or disappear entirely. 

 The pterostigma of the anterior wings is brownish, or 

 entirely wanting. 



Varieties in which the brown line of the anterior wings 

 is entirely deficient, or partially replaced by points, 

 form the following species: — G. flavus, Kolen. ; L. 

 consobrinus, Curt. Phil. Mag. 124; L. terminalis, 

 Curt. Phil. Mag. 124; L. notatus, Steph. 111. 224, 

 36 ; L. prausfus, Steph. 111. 226, 41 ; and L. flavus, 

 Steph. 111. 226, 42. 



This species may, however, always be easily distin- 

 guished from all others by the acute fifth apical cell 

 not reaching the anastomosis. 



Length 4 lin. ; exp. 7J lin. 



Hab. London, New Forest, Hertford, Coombe Wood, 

 Dover ; not uncommon from June to December. 



-ft Fifth apical cell of the anterior wing truncated, as long- 

 as the others, reaching the anastomosis.
