Discussion: E. abstemia may be separated from barberellxi by the 

 presence of an anterior white line on the third segment of the labial 

 palpus; from diadota by the ventral margin of the second segment of 

 the labial palpus having white scales; and from iobapta by the juxtal 

 lobes being heavily sclerotized on the inner basal one-third. The 

 females of abstemia and iobapta may be separated by the ostium bursae 

 being near the caudal margin of the eighth sternum in abstemia, at 

 one-third in iobapta. 



Friseria Busck 



Friseria Busck, 1939, Proc. U.S. Nat. Mus., vol. 86, p. 573. 



Type-species: (Gelechia lindenella 'Busck, 1903) =Gelechia cocker elli 

 Busck, 1903, original designation. 



Head: smooth scaled; tongue moderate, scaled to one-third or one- 

 half; maxillary palpus folded over base of tongue; labial palpus 

 recurved, second and third segments subequal in length, second seg- 

 ment slightly thicker than third, apex acute; antenna two-thirds length 

 of forewing, ciliate in male, simple in female, pecten absent. Fore- 

 wing: broadly lanceolate, apex broadly acute; 12 veins present; 7 and 

 8 stalked, 7 to costa. Hindwing: trapezoidal, outer margin gradually 

 moving to termen, apex scarcely produced; 8 veins present; 3 and 4 

 approximate to connate; 5 arching costally beyond base; 6 and 7 

 approximate to stalked, usually separate; 7 sinuous; Ki running into 

 Sc at one-fifth. Male genitalia: valva with costal lobe free, two other 

 lobes from ventral margin of costal lobe (variously developed) ; 

 vinculiun narrow laterally, saccus broadly rounded; aedeagus with 

 base expanded; tegumen broad, gnathos hook shaped; cidcitula pres- 

 ent; uncus short, caudal margin with long, stout setae. Female 

 genitalia: signum a plate with an inwardly projecting flange from each 

 end (flange very small to large and heavily sclerotized) ; eighth sternum 

 with lateral folds; ostium bursae near caudal margin of eighth ster- 

 nimi; apophyses posteriores longer than apophyses anteriores. 



Friseria is nearest to Rijseria and Srijeria. The genera may be 

 separated as indicated under Rijseria. 



Some species of Friseria have maculation very similar to that of 

 Parastega Meyrick species, and the venation of neither is diagnostic; 

 however, the male genitalia of Parastega are characterized by having 

 asymmetrical, single lobed valvae and a long uncus which lacks 

 enlarged setae on the caudal margin. The signum of Parastega is as 

 for Gelechia. 



The known species of Friseria occur in the Southwest and Mexico; 

 thus, the genus may have evolved in the Mexican highlands.
