Mate (fig. 130).—Alar expanse 18-24 mm. Frons conical. An- 
tenna weakly ciliate, cilia about one-half as long as width of shaft. 
Midtibia slightly thicker than hind tibia, hair-pencil weak. Outer 
spur about one-fifth as long as inner. Head, thorax, and abdomen 
pale ochreous above, whitish below. Labial palpus upturned, with 
third segment short, porrect, concealed by scales; palpus twice as 
long as width of eye; first segment white, second segment luteous 
above and laterally, white below, all of third segment luteous. 
Forewing: Upper surface pale yellow, somewhat subhyaline; area 
along costa and markings luteous; with three transverse lines, trans- 
verse anterior and posterior lines narrow, somewhat denticulate, 
subterminal line smooth, somewhat diffuse and broader than anterior 
and posterior lines. Anterior transverse line bent obliquely out- 
ward from costa to vein 1b, thence zig-zag inward and outward to 
hindwing margin, posterior transverse line bent slightly inward from 
origin on costa to vein 7, weakly crenulate and broadly concave 
outwardly to slightly below vein 3, almost directly inward to vein 2, 
slightly concave outwardly to vein 1b, thence directly posterior to 
hindwing margin. Subterminal line nearly straight, about midway 
between outer margin of wing and loop of transverse posterior line 
at end of cell, subparallel to outer wing margin. 
Hindwing: Upper surface coloration similar to that of forewing 
but paler, with two rather diffuse transverse lines appearing as con- 
tinuations of transverse posterior and subterminal lines of forewing. 
Postmedial line occasionally weakly crenulate, extending from costa to 
slightly below vein 2. The subterminal line smooth, parallel to outer 
margin and distinctly closer to outer wing margin than to postmedial 
line. Fringe of both fore- and hindwing concolorous with ground 
color of wing. Under surface of fore- and hindwing whitish with 
ochreous tinge; markings stronger on forewing but weaker on both 
wings than above.
