116-i THE BUTTERFLIES OF NEW ENGLAND. 



To the gav i^ardiiis his uustaid desire 

 Uiin wholly caried, to refresh his sprights: 

 There lavish Nature, in her best attire, 

 I'owres forth sweete odors and alluring slights. 



Spenser. — Muiopotmos. 



Imago (7: 1, 2; 16; 1, 2). Head covered above with dull, white hairs, scarcely 

 tinged with yellowish and with many intermingled rather longer ijlack hairs, those on 

 the front of the head mostly collected in longitndinal rows directly in front of each an- 

 teuna; behind the eye furnished with many white scales, mingled above with black. 

 Basal aud middle joints of palpi white, the apical half of the middle joint with a 

 jnedian black streak on the sides; apical joint black, white within and on the lower 

 half of the sides towards the base; inferior fringe white, overlaid externally by black 

 hairs which are abundant toward the tip, but disappear before the base. Antennae 

 blackish brown, heavily marked with white, especially on tlie basal half of eacli joint 

 outwardly above and on the apical third of the inner and outer side below; beneath 

 naked, luteons, narrowly interrupted at the incisures with white scales; club black, or 

 blackish, its inner edge blackish fuscous, the apical joint whitish, tinged with Inteous ; 

 tongue blackish fuscous, dark castaneous at the base. 



Thorax covered above with pale bluish gray hairs, becoming iron gray at the pos- 

 terior extremity of the thorax; beneath with dirty white scales and hairs; legs the 

 same, the whitish scales becoming very thin on the tarsi, showing a dull luteo-fnscous 

 base; spines luteous, pale on the tibiae; spurs yellowish, dusky .at the extreme tip; 

 claws and other appendages uniform luteous. 



Wings above white, occasionally very slightly tinged with yellowish ; fore vjings 

 either flecked at the extreme base more or less heavily with black scales mostly over- 

 laid by white ones, the basal half of the costal border dusted inconspicuously with 

 gray ( (? ) , or flecked not very heavily with griseous at the base of tlie wings at least as 

 far as the flrst divarication of the median or even to the extremity of the cell, extending 

 also over the basal half of the costal margin ( ? ) ; at the extremity of the cell is a 

 broad, transverse bar, running from the first superior subcostal nervule to the median 

 nervure, its inner edge reaching the very base of the subcostal nervule above and the 

 second divarication of the median nervure below ; the nervures are traced in whitish 

 as they pass through it and the vein closing the cell, passing through its middle, is 

 generally flecked with grayish. A little nearer the tip of the wing than the bar just 

 described is a curving broken series of similarly colored, sometimes less distinct 

 mai'kings ; the uppermost depends from the costal margin, is parallel to the middle 

 costal bar and reaches fully ( 5 ) or scarcely ( J ) to the lowest subcostal nervule; in 

 the ij it is generally much less, in the $ generally much more than half as broad as 

 the middle costal bar, blacker and yet more powdery in the J than in the ? , and in 

 the latter extending toward the apex of the wing above the third superior subcostal 

 nervule; in the middle of the outer four-fifths of the upper median interspace aud the 

 middle of the outer two-thirds of the medio-submedian interspace are other spots in 

 continuation of this series, besides which there are some clustered scales in the sub- 

 costo-median interspace, often absent from the ^ , usually extending nearly across the 

 interspace in the $ ; and in the lower median interspace sometimes, especially in the 

 ? , a few scales in a slender, transverse line; the spot in the medio-submedian inter- 

 space is generally more or less clouded or obsolete in the (J and is sometimes extended 

 to the inner border, especially In the ? , where it often extends along the border 

 toward the base with griseous fleckings ; the outer margin is generally marked, espec- 

 ially above, with a most delicate fuscous line and the extremities of the subcostal and 

 median nervules terminating on that margin, excepting the lowest median in the (J, 

 are bordered rather slenderly or somewhat broadly with blackisli ( <J ) , or very broadly 

 so as to become concurrent with blackish fuscous ( ? ), generally, especially in the g , 

 more broadly next the costal than toward the inner border ; in tlie ^ the spots are some- 

 times confined to the very apex of the wing and seldom reaches half way to the submar- 

 ginal spots ; in the $ they are usually oval or roundish and usually run into the 

 submarginal spots. Fringe white, interrupted at the nervure tips on the upper half of the
