tion partially obsciu'ed by vestiture. Eyes essentially same as those 

 of cf . Antennae simple, slender, segments largely covered by scales. 

 Wing expanse: 21 mm. 



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



Tegumen with lateral arm glabrous, of medium width, rather elon- 

 gate, narrowing somewhat to point of articulation with vinculum; 

 dorsal area glabrous, of medium width, indistinctly fusing mth base of 

 uncus. 



Harpe simple. Lateral aspect: sublinear, quite similar to that of 

 seculaius. Costa and sacculus fused, comprising somewhat more 

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

 ventrocaudal margin of sacculus, apical half evenly expanded ventrad, 

 basal half slender and sinuate; ental area from base to near apex 

 produced dorsad in form of smoothly rounded, weakly sclerotized 

 expansion extending well beyond base of arm of transtilla. Cucullus 

 indistinctly fused with costa and sacculus, elongate, slender, very 

 heavily punctate ectad and entad, sparsely setose in basal and apical 

 areas, basal two-thirds with margins sublinear and subparallel, apical 

 third somewhat expanded dorsad; apex with ventral margin broadly 

 and evenly rounded, dorsal margin produced slightly distad and very 

 narrowly rounded. 



Transtilla with arm glabrous, well sclerotized, approximately one- 

 fourth as long as harpe, linear except for extreme apex curving ventrad 

 and ectad, subparallel with costal margin, terminating subacutely 

 somewhat above base of harpe. 



Uncus simple. Dorsal aspect: base fused with tegumen and set 

 off only by heavily punctate lateral and mesal areas in basal half; 

 lateral margins heavily sclerotized, punctate and setose, sublinear, 

 evenly converging into uncal process. Uncal process distinct from 

 basal area by its greater degree of sclerotization, lateral margins 

 sparsely punctate and setose at base, length and width medium, 

 evenly curving caudo ventrad, apex subacute. 



Gnathos fused, broad, of medium length, glabrous, curving ventro- 

 caudad, ventral surface slightly concave and lateral margins directed 

 strongly downward to give hood-shaped appearance; apical portion 

 thin, somewhat upcurved, subtriangular, apex narrowly rounded. 



Anellus membranous, unarmed, juxta absent. 



Aedeagus slender, elongate, approximately as long as harpe, cylin- 

 drical, asymmetrical, glabrous, sublinear and somewhat sinuate in 

 dorsal and ventral aspects, basal and apical thirds curving somewhat 

 ventrad in lateral aspect, base slightly expanded dorsad, approximate 

 apical third opening dorsad; apex terminating ventrad in short, 

 robust, heavily sclerotized, acute, spinelike process; apex terminating
