fuscous; markings in form of brown spots along apical margin, fuscous 

 spot at outer end of cell, and brownish patch covering basal third 

 above fold; color pattern quite variable, commonly reduced to rich 

 brown ground color with several diffused luteous patches. Hindwings 

 and fringes brown. Abdomen grayish-brown; tip and apical portions 

 of genitalia covered with elongate, slender, pale brownish scales. Wing 

 expanse: 16 to 21 mm. 



Female. — Coloration generally similar to that of cf, pattern of 

 forewings not as variable as in cf . Labial palpi somewhat shorter 

 than in cf , partially recm*ved over head and extending considerably 

 above antennal bases, gradually diverging from head and from each 

 other distad. Eyes similar to those of d^ except less densely setose. 

 Antennae slender, otherwise similar to those of cf . Forewings gray- 

 ish, speckled with dark brown or fuscous, with broad patch of gray- 

 ish white extending along apical half of costa. Wing expanse: 24 to 

 27 mm, 



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



Tegumen with lateral arm elongate, slender, margins sublinear, 

 evenly narrowing to point of articulation with vinculum, narrow 

 punctate area near dorsocaudal margin; dorsal area of medium width, 

 weakly sclerotized, glabrous, cephalic margin broadly emarginate. 



Harpe simple, somewhat similar to that of piger. Lateral aspect: 

 sublinear, broadest in central thu'd of cucullus. Costa and sacculus 

 fused, of medium width, comprising approximate basal half of harpe, 

 dorsal margin heavily sclerotized, narrowing slightly to base, gla- 

 brous except for sparsely setose caudo-ental area weakly produced 

 ceplialodorsad and terminating subacutely. Cucullus partially set 

 off from costa and sacculus by areas of reduced sclerotization, heavily 

 punctate and setose in apical ental two-thirds, basal third mostly 

 glabrous, dorsal margin sublinear, basal third rather narrow and slightly 

 constricted, central third broadly and evenly expanded ventrad to al- 

 most three times width of narrowest portion of basal third, apical third 

 gi-adually and evenly narrowing ventrad to broadly and evenly rounded 

 apex. 



Transtilla with arm typical; glabrous, slightly curved and conver- 

 gent with costal margin, approximately one-fifth as long as harpe, ter- 

 minating well above base of harpe. 



Uncus bifid, essentially like that of piger. Dorsal aspect: base par- 

 tially fused with caudal margin of tegumen, partially separated by 

 areas of reduced sclerotization; mesal area weakly sclerotized, concave; 

 lateral areas heavily sclerotized, punctate, evenly converging and 

 narrowing to apices; angle of bifurcation small, very narrowly rounded; 

 furcae narrowly separated at bases, strongly convergent with resultant 

 marked overlapping of apical portions. Lateral aspect: basal and
