Food plant: Unknown. 



Type: Male, BMNH. 



Specimen examined: 



MEXICO: Guerrero: Amula, 6000 ft., Icf, Sept. 18, H. H. Smith (RWH 

 slide 3461; RWH wing slide 83), USNM. 



Discussion: F. injracta may be separated from cockerelli, caieta, 

 repentina, and nona by the presence of the costal, white fascia on the 

 forewing; from lacticaput by the dark head and thorax; and from 

 acaciella by the rounded apical portion of the fascia. The valvae of 

 the male genitalia of injracta have an extremely heavily sclerotized 

 costal lobe; the two lobes from the ventral sm-face are short; whereas 

 the costal lobe of acaciella is less heavily sclerotized, has an additional 

 ventrodistal lobe, and one of the lobes from the ventral margin is 

 more than one-half the length of the costal lobe. 



Rifseria, new genus 



Type-species: Gelechia Juscotaeniaella Chambers, 1878.

 illary palpus short, folded at base of tongue; labial palpus recurved,
