1538 THE BUTTERFLIES OF NEW ENGLAND. 



lowest subcostal iuterspace, retreat from it and again return toward it in the upper 

 median Interspace, and then regularly recede from it again ; the two upper spots and 

 that in the upper median interspace are nearly always smaller than the others, and in 

 the ? are often reduced to mere dots ; following these, and in the same interspaces, 

 occasionally wholly or partially obsolete, especially in the ? , is a series of delicate, 

 very short, longitudinal lines, seated on the black edged margin and surmounted by a 

 slightly larger dot; occasionally these are l^lended to form a series of minute 

 triangles, seated on the margin, wliicli is always narrowly edged with black; fringe 

 white, interrupted abruptly, distinctly and not very narrowly with blackish at the uerv- 

 nle tips, often more broadly in the 2 tl"in in the J , and in the former occasionally ob- 

 scured by brownish. Smd wings having the lower half of the wing, excepting the inner 

 margin, covered with long, longitudinal, greenish gray hairs, especially next the nerv- 

 ures, the longest next the subniedian ner^^lre ; an arcuate, unequal band of white spots 

 crosses the middle of the outer four-fifths of the wing, extending from the costal 

 nervure to the middle of the raedio-submedian interspace, broader and far more con- 

 spicuous in the ^ tlian in the $ ; above the upper median nervide it is of about equal 

 width, the largest spot, in the middle of the wing, running from the last divarication 

 of the subcostal and median nervures nearly or quite half way to the outer border; 

 below, it is of half the width, removed a little further inwards, at least below the 

 middle median nervule, and generally tapers a little as it proceeds. A small, obscure 

 spot is sometimes seen in the middle of the upper half of the cell ; there is a submar- 

 ginal series of six or seven roundish spots below the upper subcostal nervule, subpar- 

 alk'l to the outer border, but approaching it a very little more closely beyond the cell 

 than elsewhere, often reduced to dots in the $ , and usually about an interspace's dis- 

 tance from the border ; these are accompanied Ijy a series of six dots seated on the 

 margin, the spot in the lower half of the medio-subraedian interspace having none; 

 some or all are sometimes absent from the ? ; the margin is delicately edged with 

 black; fringe white, the basal half, occasionally the whole, narrowly and abruptly in- 

 terrupted with blackish at the nervule tips. 



Beneath : Fore wirujs much paler brown than above, often faintly tinged with oliva- 

 ceous; the white markings of the upper surface are repeated but on a slightly enlarged 

 scale, so that esjiecially along the costal area they become partially or even wholly 

 confluent, with only dusky nervules to break the uniformity ; the upper half of the 

 basal two-flfths of the wing is also more or less bathed in white, and the apex of the 

 wing, beyond the triple series of subcostal spots, is clouded with olivaceous, followed 

 below, as far as the upper median nervule, by a white patch ; the outer border is 

 delicately edged with black, and more distinctly dotted in the middle of the interspaces, 

 to which indeed the outer edging is occasionally confined ; fringe much as above but 

 the blackish interruptions usually somewhat fan-shaped, spreading from the border. 

 Hind wings varying from greenish clay brown to a simple pale brown like that of the 

 fore wings, but usually more or less tinged with greenish; the white markings of tlie 

 upper surface are repeated beneath, more or less distinctly edged with black — generally 

 with varying intensity — the mesiaf band broader and continuous, extending from the 

 costal nervure to the submedian ; the submarginal spots are accompanied by smaller, 

 cloudy white, marginal spots, occasionally blending with the subnicarginal series; 

 in addition, midway between the mesial band and the base is a narrow, whitish, irre- 

 gular, transverse, externally black edged stripe, farthest removed from the base in the 

 costo-subcostal interspace and there edged also internally with black ; the costal and 

 inner margins as far respectively as the costal and submedian nervures are dull whitish, 

 usually powdered, particularly on the inner margin, with dusky scales; on the costal 

 border there is a small, transverse, blackish bar at the extreme base and another 

 shorter, but little removed from it, often connected along the margin iDy a Ijlackish 

 line so as to make a virgulate mark ; on the inner margin the dusky flecking becomes 

 intensified next the outer margin and forms a fuliginous spot, sometimes the only 

 marking on the margin ; outer margin edged and tiotted witli black like the fore 

 wings, the fringe as on the upper surface.
