pale areas minutely sprinkled with fuscous in apical third and below 

 fold. Hindwings glossy brown, fringes slightly lighter. Abdomen 

 brown. Wing expanse: 13 to 15 mm. 



Male genitalia. — Vinculum typical, as in other species. 



Tegumen with lateral arm glabrous, broad, evenly narrowing to 

 point of articulation with vinculum, margins sublinear; dorsal area 

 glabrous, broad, fusing into base of uncus. 



Harpe simple. Lateral aspect: sublinear, somewhat similar to 

 that of simulatus. Costa and sacculus fused, comprising slightly 

 more than basal half of harpe, glabrous except for punctate and 

 setose ventrocaudal margin of sacculus, apical half evenly expanded 

 dorsad and ventrad, basal half extremely slender; ental area from 

 base to apex produced dorsad in form of large, rounded, rather 

 weakly sclerotized expansion extending considerably beyond base of 

 arm of transtilla. Cucullus rather indistinctly fused with costa 

 and sacculus, elongate, slender, heavily punctate, sparsely setose 

 (especially in basal and apical areas), margins sublinear and parallel; 

 apex with ventral portion broadly and evenly rounded, dorsal portion 

 produced somewhat distad and narrowly rounded. 



Transtilla with arm glabrous, well sclerotized, approximately one- 

 fourth as long as harpe, diverging considerably from costal margin, 

 apical portion curving strongly ventrad toward costal margin, termi- 

 nating sub acutely somewhat above base of harpe. 



Uncus simple. Dorsal aspect: base fused with tegumen; heavily 

 punctate except for narrow, glabrous, mesal area; lateral margins well 

 sclerotized, linear, evenly conv^erging into uncal process. Uncal proc- 

 ess distinct from basal area by its greater degree of sclerotization, 

 glabrous, length and width medium, curving caudoventrad, apex acute. 



Gnathos fused, short, broad, rather weakly sclerotized, curving 

 almost directly ventrad; apical portion thin, flattened, finely scobinate 

 entad; apex broadly and evenly rounded. 



Anellus membranous, unarmed, juxta absent. 



Aedeagus elongate, slender, subsymmetrical, glabrous, sublinear 

 in dorsal and ventral aspects, basal half irregularly curving ventrad 

 through angle of approximately 90° in lateral aspect, apical half with 

 some additional ventral curvature; approximate basal fifth slightly 

 expanded, cylindrical; approximate apical four-fifths opening dorsad 

 with aperture becoming gradually wider distad throughout central 

 third of aedeagus and resulting in reduction of apical third to very 

 slender, linear, well sclerotized, ventral strip terminating subacutely. 



Vesica membranous, unai-med, slender, extremely elongate, arising 

 dorsad from approximate apical four-fifths of aedeagus but well ex- 

 truded only from approximate apical half of aedeagus. 



Type. — Holotype cT (type no. 61449) in the U.S. National Museum.
