120() THE BUTTERFLIES OF NEW ENGLAND. 



Basal fourth of tongue pale liiteous, fusco-f uliginous, with a greenish tinge beyond ; 

 papillae (61 : 52) few, very distant, small, cylindrical, no longer than broad, with a 

 small central lllamont. 



Thorax covered above with pale plumbeous hairs, on the prothorax, and to some 

 degree on the edges of the patagia, tinged apically with pale sulphureous, on the 

 front of the rest of the thorax with pale greenish gray ; beneath covered with pale 

 greenish gray hairs, tinged slightly with yellowish, and mingled with a few blackish 

 hairs; legs black, tinged with brown on the tibiae and tarsi, the femora tinged with 

 greenish gray and a few black hairs, thickly covered with white scales tinged pretty 

 strongly with yellow toward the base, and leaving a streak of black just above the 

 middle of the outer half of the anterior surface, and a shorter apical streak on the 

 posterior edge of the upper surface ; tibiae thickly clothed with white scales, which 

 are absent from two slender stripes down either side of the outer surface, in continua- 

 tion of those of the femora, most distinct on the fore legs, least so on the hind ; tarsi 

 flecked M'ith a few white scales ; spines pale brownish luteous ; spurs blackish casta- 

 neous at tip ; claws and all the apical appendages blackish fuliginous. 



Wings above dull white, occasionally tinged with yellowish, especially in the $ ; 

 outer margin of fore wing's nearly straight ; the wings pretty heavily flecked with 

 griseous at the extreme base, rather less heavily along the basal half of the costal 

 border, as far as the upper margin of the cell ; in the ? also faintly powdered with 

 grayscales over the whole basal half of the wing, fading out apically; the costal 

 edge is griseous; at the apex of the wing there is a blackish griseons spot, made up 

 of a more or. less dense sprinkling of dark scales, extending over a larger portion of 

 the costal than of the outer border, and vaguely limited interiorly by a nearly straight 

 line, running from a little before the extremity of the second superior subcostal 

 uervule to the outer border at the middle of the lower subcostal interspace; scarcely 

 before the middle of the upper median interspace is a round or quadrate, blackish 

 griseous spot of varying intensity and size, but seldom equalling the width of the 

 interspace ; it is occasionally wanting in the $ ; in addition the ? has a similar, gen- 

 erally smaller and transverse, frequently geminate spot in the medio-submedian inter- 

 space, at a little more than half way from the base to the tip of the lower median 

 nervule; usually it is connected at its lower extremity with a powdery, rather broad, 

 longitudinal, griseous streak running to the base next the inner margin. Fringe uni- 

 form white. Hind wings scarcely angulated in the subcostal region, not conspicuously 

 prominent in the upper half of the outer margin ; wings flecked at the extreme base 

 ■with griseous, as in the fore wings, generally extending outward a little further on the 

 median nervure ; in the $ the basal half flecked to some degree, especially along the 

 median nervure, but less heavily than on the fore wings; on the costal margin, its 

 outer limit at the tip of the upper subcostal nervule, a transverse oblique spot, similar 

 in color and intensity to those on the fore wings, directed outward in passing down- 

 ward, reaches nearly to the middle subcostal nervule. Fringe white. 



Beneath, /ore wing's white, delicately tinged with lemon yellow at the apex of the 

 wing, from half way between the apex of the cell and the tip of the wing ; also 

 generally, but still more faintly tinged with the same along the costal margin, and 

 occasionally, in specimens where the upper surface is tinged with yellow, bathed very 

 faintly throughout in yellow, deepest on the parts mentioned ; a few griseous scales 

 are scattered distantly over the whole wing, but especially over the basal half of the 

 cell and along the basal two-thirds of the costal margin; the spots of the upper sur- 

 face are repeated beneath, but almost invarialjly some trace at least of the spot in the 

 medio-sulimedian interspace is found in the $ also; while at the same time the 

 griseous streak which usually accompanies it above does not occur in the $ , and but 

 seldom, and then greatly diminished, in the $. Fringe white, occasionally a little yel- 

 lowish. Hind wings pale or deeper lemon yellow, the basal third of the costal edge 

 pale orange; the whole wing pretty uniformly flecked, sometimes very lightly, at 

 others quite heavily, with griseous scales, generally less abundant in the apical fourth 

 of the wing and in lines down the middle of the interspaces, and usually most con-
