THE BUTTERFLIES OF NEW ENGLAND. 



Beneath paler brown than above, more or less tinged, and more on the hind than the 

 fore wiiiRS, with dirty olivaceous green. Fore loings powdered throughout, but not 

 unifonnly nor alwa3's with the same intensity in the same regions, with white scales 

 giving the wing a grayish aspect; the marlsings of the upper surface are repeated be- 

 neath, slightly enlarged and, notably, the spots of the extra-mesial series are usually 

 united in a continuous angulated band, often obscurely bordered with dark brown on 

 the interior side; the nervules in the outer two-flfths of the wing are often traced in 

 dull white and the outer border is often profusely sprinkled with white scales ; the 

 costal and outer margin and the fringe are as upon the upper surface. Hind wings 

 crossed by three dull white bands : the inner is formed of three pretty large, inde- 

 pendent, more or less quadrate spots, one in the middle of the basal half of the costo- 

 subcostal interspace, a smaller one at the extreme base of the cell, its outer limits 

 nearly touching tlie inner limits of the previous spot, and a similar one in the medio, 

 submedian interspace below the first divarication of the median nervure; there is often 

 also a small curving dash at the base of the costal nervure ; the second tjand is a con- 

 tinuous, irregular, broad, but variable mesial stripe, running from the costal to the sub- 

 median nervure; in the costo-subcostal interspace it is obliquely lunate; in the 

 subcostal interspaces It extends from the extreme base nearly half way to the outer 

 margin ; beyond the cell it forms a broad spot whose outer limit is like that of the 

 neighboring part of the band above, and whose inner limit Is straight and at the second 

 divarication of the median nervure ; in the upper median interspace it occupies only 

 the extreme base, traverses the lower median interspace rather narrowly opposite the 

 second divarication of the median nervure and without reaching the base of the inter- 

 space, continues in the same direction across the interspace below, broadening as it 

 goes, terminating on the submedian with its inner limits at the middle of the nervure; 

 the outer band consists of a regular, gently curving series of small, subequal, vague, 

 roundish or arrow head spots in the middle of the interspaces, from the upper sub- 

 costal to the submedian nervules, lying midway between the middle band and the 

 outer border, except in approaching the latter below the median nervules. The 

 whole wing is covered rather sparsely with long white or greenish white hairs and 

 scales, giving it a slightly hoary aspect, not so conspicuously, however, as on the 

 fore wing; and in addition the costal and inner border and, frequently in a greater 

 degree, parts or the whole of the outer border are rather profusely flecked with 

 white, or on the outer border with pale greenish yellow; outer border occasionally 

 edged with black. Fringe as on the upper surface. 



Abdomen blackish brown, covered abundantly above with greenish gray hairs, 

 beneath largely enlivened with paler hairs, and at the apices of the joints with similar 

 pale scales; hairs of the terminal joint very pale, dull, greenish yellow. Upper organ 

 of male appendages (35:45) with the hook arched, compressed, long and slender, 

 tapering, pointed, sulcate above on basal half, separated from the centrum, which it 

 equals in length, by a distinct constriction ; lateral arms bearing beneath a com- 

 pressed lamina, reaching scarcely beyond the base of the hook. Clasps about two and 

 a half times longer than broad, narrowing pretty regularly, well rounded at the tip, 

 the apical portiou rising as high as the upper lobe from which it is separated, and 

 which is marked only by a deep, narrow, .slightly recurved excision, extending two- 

 thirds way across the blade. 



Described from 4 3 , 3 $ . 

 Accessory sexual peculiarities. In the fold of the costal margin of the male fore 

 wing occur some exceedingly delicate, elongated, lanceolate scales, tapering to the
