Figures 181-183 



Male.- — Head, labial palpi, and thorax ochreous tinged with white 

 and fuscous. Labial palpi short, partially recurved but not extending 

 to antennal bases, rather narrowly separated from each other, closely 

 appressed to head except at apices, densely clothed with slender scales. 

 Eyes large, protruding, naked, weakly lashed. Antennae unipecti- 

 nate, ochreous, covered dorsolaterad \vith scales; segmental processes 

 (fig. 181) subcircular in transverse section, developed ventrad rather 

 than laterad, somewhat thickened but well separated from one another 

 in lateral aspect, free of scales but covered with elongate setae. Fore- 

 wings with variable color pattern, ground color pale brown, finely 

 sprinkled with fuscous, marked with dark brown; markings consisting 

 of faint spots along costa, narrow bar at outer end of cell, and irregular 

 patch extending from fold to center of posterior margin. Hindwings 

 pale brown, fringes brownish-white. Abdomen pale brown, covered 

 with broad scales rather densely overlaid with very slender scales or 

 hair. Wing expanse: 24 to 30 mm. 



Female. — Coloration similar to that of cT, pattern variable as 

 in c^. Labial palpi slightly shorter than those of d', directed upward 

 and forward, narrowly separated from each other, basal halves closely 

 appressed to head, densely clothed with both broad and slender scales. 

 Eyes essentially same as those of d^. Antennae similar to those of cf 

 but with segmental processes considerably smaller. Forewings brown, 

 heavily sprinkled with fuscous. Hindwings, fringes, and abdomen 

 colored as in cf . Wing expanse: 26 to 29 mm. 



Male genitalia. — Vinculum in form of rather narrow, heavily 

 sclerotized, lateroventral band. 



Tegumen glabrous; lateral arm rather broad but gradually nar- 

 rowing to point of articulation with vinculum, cephalic margin sinuate, 

 caudal margin sublinear and well sclerotized ; dorsal area very broad, 

 cephalic margin sinuate and with broad but shallow mesal emargina- 

 tion, caudal margin fusing mesad with base of uncus. 



Harpe simple, broad. Lateral aspect: costa and sacculus fused, 

 comprising somewhat more than basal half of harpe, glabrous except 

 for large punctate and setose ventrocaudal area of sacculus, broadest 

 at point of attachment of arm of transtilla, approximate basal half
