and diffused patch beneath center of fold. Hindwings dark brown, 

 fringes somewhat hghter. Abdomen brown. Wing expanse: 22 to 

 26 mm. 



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

 cT. Labial palpi and eyes similar to those of cf. Antennae slender, 

 almost entirely covered by scales, segments globose rather than 

 laminate. Wing expanse: 27 to 29 mm. 



Male genitalia. — Vinculum rather large and well sclerotized, but 

 otherwise typical. 



Tegumen fairly broad, glabrous; lateral arm somewhat shortened, 

 evenly narrowing to point of articulation with vinculum, margins 

 linear; dorsal area with cephalic margin minutely emarginate mesad, 

 caudal margin with deep and irregular mesal emargination filled by 

 area of weak sclerotization. 



Harpe divided, with reduced costal process. Lateral aspect: 

 costa and sacculus fused, large, considerably expanded in all aspects, 

 comprising approximate basal half of harpe, glabrous except for 

 punctate area along ventrocaudal margin of sacculus bearing elon- 

 gate setae, broadest in apical portion caudad of point of attach- 

 ment of arm of transtilla, approximate basal five-sevenths evenly 

 narrowing dorsad and ventrad toward narrowly rounded basal 

 extremity; costal process not greatly developed but very distinct, 

 slightly shorter than arm of transtilla, originating at dorsocaudal 

 extremity of costa, base broad, margins converging caudad to rather 

 narrowly rounded apex, directed caudad and curving somewhat 

 mesad, dorsal margin evenly continuous with that of arm of trans- 

 tilla. Cucullus separated dorsad from costa and ventrad from 

 sacculus by areas of reduced sclerotization, directed somewhat ven- 

 trad, approximate central half considerably flattened dorsoventrad and 

 appearing quite slender in lateral aspect, approximate apical half of 

 ventral margin heavily punctate and setose entad, remainder of 

 cucullus very sparsely punctate and setose, approximate basal half 

 with dorsal and ventral margins heavily sclerotized, basal and apical 

 thirds somewhat expanded dorsad and ventrad; apex broad, dorsal 

 margin broadly and evenly rounded, ventral margin narrowly rounded. 



Transtilla with arm short, stout, well sclerotized, glabrous, approxi- 

 mately one-sixth as long as harpe, broadly separated from and ex- 

 tending subparallel to dorsal margin of costa, terminating subacutely 

 far caudad of basal extremity of harpe. 



Uncus obscurely bifid. Dorsal aspect: base rather small, glabrous, 

 entirely set off from tegumen by broad areas of reduced sclerotization, 

 lateral margins heavily sclerotized and converging rather sharply 

 distad into main uncal process; angle of bifurcation minute, acute, 

 located approximately at midpoint of main uncal process; furcae
