15. Genus PHAECASIOPHORA Grote 



(Figs. 16, 61, 233) 

 Phaccasiophora Grote, Bull. Buffalo Soc. Nat. Sci., vol. 1, 1873, p. 90. 



Genotype. — {Sericoris mutahilana Clemens) =8ciaphila confixana 

 Walker (North America). 



Thorax with posterior tuft. 



Forewing smooth; termen convex; 12 veins, all separate; 7 to 

 termen; 8 and 9 approximate; upper internal vein of cell from 

 between 10-11 ; 3, 4, and 5 not approximate at termen ; 2 from cell 

 at %, very slightly bent. 



Hind wing wifh 8 veins; G and 7 approximate toward base; 3 

 and 4 connate; termen nowhere notched; in male with chitinous 

 ridge on inner margin. 



Hind tibia of male heavily tufted with scales (less so in nivei- 

 guttana) and Avith strong yellow hair pencile from base. 



Male genitalia with harpe elongate, broadened beyond base; 

 outer surface unspined; cucullus long and narrow, evenly spined 

 throughout, apex bluntly pointed; sacculus simple, weakly spined 

 toward base; spine clusters Spc^ and Sj)c^ not developed. Uncus 

 absent. Socii large, oval-triangular, flexible, finely haired. 

 Gnathos a simple, weakly chitinized band, without subanal plate. 

 Aedoeagus short, stout, straight; cornuti a cluster of long, slender, 

 deciduous spines. 



Female genitalia without signum. Ductus bursae moderately long, 

 chitinized for part of its length, toward genital opening. 



Directly derived from Olethreutes. Contains two North American 

 species. The male character upon which the genus was originally 

 established (broadly tufted hind tibia) is decidedly less obvious in 

 niveiguttana than the type ; but is present in both species.
