Male. — Antenna bipectinate. Palpi, head, and thorax grayish fus- 

 cous dusted Avith wliite. Fore wing graj'ish fuscous dusted with 

 white and more or less blotched with black; some specimens with a 

 faint ocherous-fuscous tint in the middle of the cell and on the area 

 between vein lb and the cell; normally with antemedial and subtermi- 

 nal transverse markings indistinct, but indicated by whitish angu- 

 late and dentate bands shaded inwardly and outwardly by black; 

 a blackish shade at end of cell, often extending to costa; below it on 

 inner margin a similar dark spot ; veins 2 to 8 faintly lined with black 

 and in many specimens the fold to a little beyond its middle. Hind 

 wing white, semihyaline, shaded in costal area above vein 6 and cell 

 with pale fuscous, with some fuscous scaling on the veins and a fine 

 fuscous line along termen; anal margin and adjoining cilia faintly 

 ocherous; cilia otherwise white, with a narrow, fuscous, subbasal line. 



Alar expanse, 36-47 mm. 



Male genitalia essentially like those of Jongipennella but somewhat 

 larger, in size and habitus like those of macidifera. 



Female. — In color and markings like the male except that there is 

 never any black streak on the fold of the fore wing; some specimens 

 are heavily dusted with black over the entire base of the fore wing 

 as far as the antemedial line; others have the transverse lines and 

 contrasted dark spots almost obliterated and the wing of a pale 

 slate-color with only the faintest remnants of the normal markings. 



Alar expanse, 34-50 mm. 



Genitalia (figs. 73-73a) with the sclerotized ventral plate in ductus 

 bursae at genital opening smaller than those in longipennella, insig- 

 nafella, and maculifera.
