costal venule arising remotely from its vei:i ; in Acidalia, the venule arises 

 directly from it, the end of the cell being acute. Legs very long and slender. 

 Hind legs very long; tibiae not swollen; spurs long; tarsi nearly as long as 

 the tibiae. Abdomen reaching beyond the hind angle. Coloration: brown- 

 ish-ochreons, with darker lines, the extracliscal sometimes broadly shaded. 



This genus may at once be known by the plumose male antenna?, the 

 falcate fore wings and very acutely-angled hind wings. 



Larva and pupa. — ''Caterpillars carinated on the sides, much swollen 

 on the fourth segment ; head small, a little squarish ; living concealed under 

 low plants. Chrysalides slender, swollen beneath, with the head prolonged 

 into a point; resting between leaves." — Guenee.

7 S and 2 9. — Pale fawn; vertex a little paler; front a little darker; 

 antenna; of the same color with the rest of the body. Fore wings dusted 

 with scattered brown specks ; three dull-pink, often brownish, lines on the 

 fore wing; inner oblique, curved hair-line in the middle of the wing; a 

 slight transverse discal dot ; an outer oblique line going straight from the 

 middle of the inner margin to near the apex, where it almost touches the 

 submarginal line, and is then curved back upon the costa, becoming much 

 narrower and almost obsolete ; the submarginal line slenderer than the outer 

 line, and sinuate, having a great curve a little below the middle of the wing; 

 toward the apex it becomes oblique, dark, uncurved, and appears as if the 

 continuation of the outer line; edge of wing deep pink, fringe pale, inter- 

 rupted at ends of venules with pink spots. Two similar lines on hind wings; 

 basal sometimes broader than outer, slightly curved, sometimes straight; 

 outer line parallel with it, a little curved; edge of wing and fringe as in fore 

 wing; beneath, slightly paler than above, and flecked with large transverse 

 pink specks; discal dot transverse; lines as above, but deeper pink. In 

 some specimens, the lines appear dull and faded into brown. Female larger 

 (inner line wanting in one rubbed specimen), with the outer line more angu- 

 lated in middle of the wing than in the male. The deep pink-brown of the 

 wings and lines in some cases becomes dull, almost pure brown. 



Length of body, <?, 0.35; of fore wing, <?, 0.00, 9, 0.66; expanse of 

 wings, 1.05—1.32 inches.
