176 BuscL — Notes on Some Tortricid Genera 



are of greater significance tlian would be the case in more dif- 

 ferentiated families. 



The following characters are common to the two genera and 

 apply to l)otli sexes: Antennae about i, simple or with very 

 short ciliation at the tip of each joint; labial palpi moderate, 

 reaching about the length of the head in front of the face, por- 

 rected; second joint with large, laterally compressed triangular 

 tuft ; terminae joint relatively long, though shorter than second 

 joint, deflexed, parallel with and nearly obscured by the hairs 

 of the tuft; face smooth, head round with the scales meeting on 

 top; eyes large, salient; ocelli large, placed just above the eyes 

 behind the base of the antennae; tongue short, spiraled; max- 

 ilary palpi obsolete. Thorax smooth. Fore wing with termen 

 more or less sinuate, sometimes abruptly broken below apex; 12 

 veins ; Ih straight, furcate at base ; a trace of Ic at the edge of the 

 wing; 2 from about f of cell ; 3 from corner of cell; 7, 8 and 

 9 equidistant at base; 7 to termen; 11 equidistant from 10 

 and 12; upper internal vein from between 10 and 11 to between 

 7 and 8 (in sequana obsolete) ; inferior internal vein with upper 

 fork obsolete, lower fork to between 4 and 5, 



Hind wings broader than the fore wings ; dorsal edge evenly 

 rounded from apex to base; costal edge slightly and evenly 

 rounded; termen sometimes slightly sinuate; S veins; 8 con- 

 nected with cell near base by oblique, sometimes semi-obsolete 

 crossbar; la and Ir present; 1/^ strongly furcate at base ; base 

 of median vein hairy ; 3 and 4 connate or short-stalked ; 5 

 distant from and pai'allel with 4 ; (> and 7 remote at base and 

 nearly parallel. Male genitalia with uncus rudimentary. 



All the species feed in the roots or shoots of Compositae. 



Two European species have been placed in the American list 

 namely, cdpinana Treitschke, and plvmhana ^copoli, but their 

 occurrence in America seems so highly improba1)le that I sus- 

 pect the records must be based on misidentification of closely 

 allied species and I propose to omit them until further evidence 

 is at hand. 



The American species at present known may be separated by 

 the following synoptic table :
