AMERICAN LEPIDOPTERA. 19? 



branch of same nervure; through this band runs an indistinct undu- 

 lating brown line, parallel to and near the margin ; beyond upper 

 branch of median the space between this line and margin is brown, 

 color of apex of primaries; fringes of primaries black at tips of 

 nervules, yellow-white in the interspaces, of secondaries nearly all 

 fuscous, there being but a few gray hairs in each interspace. 



Under side smoky-brown; the white spots repeated, enlarged three- 

 fold, each forming the pupil of a rounded black ocellus ; secondaries 

 have a broad extra-discal band, ferruginous and lilac, with scattered 

 yellow scales, on the posterior half of wing, lilac on brown ground 

 apically ; on the anterior edge of the band, upon small ferruginous 

 spaces free from lilac, is a row of straw-colored points and spots, com- 

 mencing in a point on the lower sub-costal interspace and continuing to 

 sub-median nervure, just before which are two points ; the three spots 

 on the three median interspaces crescent or V-shaped ; in some cases 

 these larger spots re-appear on upper side ; posterior to the band, the 

 sub-marginal area is brown, sharply lunated, each lunation formino- 

 internally a semi-circle, and through all runs a streak of ferruginous, 

 more or less irrorated with yellow; sometimes the streak is limited to 

 the three interspaces next abdominal margin. 



Body blackish-brown ; legs brown and gray ; palpi gray in front, 

 blackish above and at tip ; antennae brown, grayish next club, gray 

 below ; club yellowish.
