A REVIEW OF THE TORTRICID SUBFAMILY 

 PHALONIINAE WITH DESCRIPTIONS OF 

 NEW AMERICAN SPECIES. 



By August Busck. 

 Washington, D. C. 



The subfamily Phaloniinae comprises a natural group of moths, 

 which are easily distinguished from all other Tortricidse by having 

 vein 2 in the fore wings emitted from the outer fourth of the cell. 

 This character is always diagnostic. Several other characters are 

 more or less common and pecuHar to the species of the group, and 

 the general habitus normally indicates the subfamily to a student 

 of Tortricidae, but the above named character is the safest final 

 guide for the determination. 



The genera of this subfamily are well separated on the venation 

 alone without resort to the costal fold on the fore wings of 

 the males which is objectionable as a generic character. The 

 presence or absence of this fold with our present knowledge seems 

 nearly persistent within the genera of the group ; but it would not 

 be surprising to find exceptions,* when our fauna becomes better 

 known, and the character should not be depended upon as of 

 more than specific value. 



The following synoptic table may be utilized in separating the 

 American and European genera of Phaloniinae at present recog- 

 nized. 

 i, • Synoptic Table of the Genera of Phaloniin.-e. 



Hind wings with a!! veins present ; no pecten on median vein i 



Hind wings with but 6 veins; median vein with pecten Carposina.

Fore wing with veins 7 and 8 separate or connate 3 



*Orie exception is found in Commopliila duponcheliana Duponche!, which 

 has a very small costal fold, while the other species of the genus, to which it 

 is undoubtedly properly referred, have no costal fold.
