another at the base of the costo-subcostal interspace ; the costal ner- 

 vure also is edged above with white throughout its extent ; a narrow, 

 zigzag black band extends across the middle of the wing, bordering 

 the upper side of the second silvery spot on its course, itself generally 

 very narrowly edged with white above; within this black band, next 

 the inner border, the surface is frequently powdered with whitish or 

 ochraceous scales; beyond the black band is another broader band of 

 white or silvery lunules whose general trend is nearly straight, but 

 slightly curved ; it rests against the outer angles of the black band 

 along the inner half of its course, often indistinct near the middle, and 

 broader and less defined upon the outer half; the spaces left between 

 the black and silvery band at the outer half are ochraceous yellow 

 between the subcostal nervules, and cinnamon-red between the costal 

 and subcostal nervures ; the outer border of the wing is narrowly 

 edged with black, and has silvery triangular or lozenge-shaped spots 

 situated between the nervules, tipped with sagittate black spots ; the 

 space between these and the silvery band is of a pale cinnamon-red 

 with scattered ochraceous scales, which indeed occupy the greater 

 portion of the interspaces upon either side of the upper median ner- 

 vule; the row of round black spots of the upper surface is repeated 

 beneath, though often but indistinctly. 



Head and front of thorax covered with fulvous hairs ; the upper 

 surface of thorax and abdomen with brownish hairs, interspersed with 

 fulvous upon the sides of the abdomen ; below pale yellowish ; palpi 

 with pale hairs below, mingled fulvous and black upon the tip ; stalk 

 of antennae white below, black above, with fulvous annulations at 

 the extremity of the joints ; club of antennas black with narrow ful- 

 vous annulations. Expanse of wings' 38,5-45 mm. The males and 

 females do not differ in their markings. 22 specimens, 12 d", 6 $, 4

This is the butterfly quoted by me as Arg. Boisduvalii Somm. in 

 Packard's View of the lepidopterous fauna of Labrador, 1 and also 

 distributed by me in former years under the MS. name of A rg. Oenone. 

 Boisduvalii is a synonyme of Chariclea.
