NO. 3547 NEARCTIC GELECHIIDAE HODGES 53 



Busck (1939) proposed Friseria for cockerelli, lindenella, malindella, 

 sarcochlora, repentina, and fuscotaeniaella. Of these lindenella, malin- 

 della, and sarcochlora are synonyms of cockerelli, and fuscotaeniaella is 

 removed to Rifseria, new genus; F. infracta (Walsingham) and 

 lacticaput (Walsingham) are transferred from Gelechia, and acaciella 

 (Busck) is transferred from ''Telphusa." Two new species, nona and 

 caieta, are described, bringing the number of recognized species to 

 seven. 



Key to Species of Friseria 



BASED ON MACULATION 



1. Fore wing white overlaid with black; two patches of raised scales on fold, one 



dorsad of fold, and one at end of cell caieta, new species 



Forewing brown, no patches of raised scales 2 



2. Forewing dark purplish brown basally, followed by an oblique white or buff 



fascia running from costa to half way between fold and dorsum 5 



Forewing pale brown basally, if dark brown, not followed by pale colored 

 fascia 3 



3. Forewing with middle third purplish black 4 



Forewing varying shades of brown, never with a broad black band at mid- 

 dle cockerelli (Busck) 



4. Forewing with an obhque dark brown fascia at one-third, bordered basally 



by orange scales; outer third of costal margin uniformly dark with black 



tipped, gray scales repentina (Walsingham) 



Forewing usually lacking complete dark brown fascia at one-third; costal 

 margin pale orange brown with dark streaks, scales usually tipped with 

 white, preceded by black nona, new species 



5. Head and basal half of thorax uniformly butf . . . lacticaput (Walsingham) 

 Head and thorax mottled brown 6 



6. Apex of white fascia attenuated (fig. 52) acaciella (Busck) 



Apex of white fascia not attenuated (fig. 54) .... infracta (Walsingham) 



BASED ON MALE GENITALIA 



1. Culcitula spined 2 



Culcitula bare cockerelli (Busck) 



2. Culcitula large, extending laterally beyond base of gnathos, culcitular setae 



more than twice medial height of culcitula (fig. 112) 3 



Culcitula small, not extending laterally beyond base of gnathos; culcitular 

 setae not extending laterally beyond base of gnathos; culcitular setae less 

 than one-fourth medial height of culcitula (fig. 118) 4 



3. Medial lobe of valva with distal margin convex, apex truncate (fig. 116). 



nona, new species 

 Medial lobe of valva with distal margin sinuate, apex acute (fig. 122). 



repentina (Walsingham) 



4. Costal lobe of valva with a lobe from ventral surface at one-half its length, 



valva appearing quadrilobate (fig. 117) acaciella (Busck) 



Costal lobe of valva lacking such a lobe, valva appearing trilobate (fig. 113) .5 



5. Costal lobe of valva with a ventral flange on distal half 6 



Costal lobe of valva without a ventral flange on distal half (fig. 120), 



lacticaput (Walsingham)
