1642 THE BUTTERFLIES OF NEW ENGLAND. 



of an orange hno; the onter lateral ansleof middle joint with a row of blackish hairs; 

 the upper surface of tlie same joint wliere appressed against tlie head, l5ut not beyond, 

 blackish ; apical joint blackish. Antennae above with a narrow band of purplish black 

 much infringed upon bj' orange tawny, with which the rest of the antenna is covered 

 but which pales beneath almost to whitish, especially toward the outside; apical half 

 of club beneath and the crook naked and dark orange, the apical joint dusky. Tongue 

 black, the tip dark castaneous. 



Thorax covered above with deep greenish yellow hairs inclining to brown especially 

 behind ; below with greenish buft' hairs. Legs rather deep buff becoming dusky toward 

 the extremities above, the femora yellowish beneath. Leaf-like appendage l)ufl", the 

 spurs buff, red-tipped, spines reddish luteous, claws reddish fuscous, pad dusky. 



Wings above tawny, paling slightly toward the outer border, especially in the fore 

 wings. Fore uHnys with the outer margin broadly bordered with blackish brown, the 

 Interior border usuallj' pretty strongly crenulate and in general forming a pretty regu- 

 lar curve from about the middle of the outer two-fifths of the costal border to the 

 middle of the outer two-thirds of the inner border; but in the interspaces beyond the 

 cell it is suddenly removed outward half the distance to the outer border; in the $ it 

 is usually a little broader than in the (J ; following it inwardly in tlie interspaces be- 

 yond the cell is a large, oblong, dusky patch deepening to blackish brown outwardly, 

 occasionally, in the <J , partially obsolete inwardly ; it reaches from the extremity of the 

 cell to the outer bordering, its exterior angles just failing to touch it; in the $ almost 

 always, in the $ often, it is followed above its basal half by a dusky patch which ex- 

 tends to the costal margin, has a well-defined exterior margin parallel to the outer 

 bordering but interiorly blends into the tawny or, in the $ , extends along the costal 

 margin broadening the blackish edge always found there ; the inner border as far as 

 the submedian nervure is generally slightly dusk}' in the f, almost as dark as the 

 outer border in the ? ; besides, in the $ , there is a slender dark .streak in the cell, and 

 below it, nearly or quite to the last divarication of the median, a broad, dusky or black- 

 ish brown, longitudinal patch, replacing tlie ^ dash; the latter (43 : 15; 45 : 1) is velvety 

 black with a median slit, giving the appcar.ance of a hoary line; it extends from the 

 last divarication of the median to a point scarcely outside of the middle of the basal 

 half of the submedian, is slightly fusiform, tapering more outwardly than inwardly, 

 very slightly arcuate, its convexity above and nearly eight times as long as broad. 

 The edge of the outer border is marked in blackish, the upper two median nerv- 

 ules and occasionally some of the others, especially toward the apes of the wing, are 

 delicately and indistinctly traced in brownish; fringe dirty pale brown, palest out- 

 wardly and especially on the lower half of the wing. Hind wings completely bordered 

 throughout with blackish brown so as to leave only a central disc of tawny, in which 

 the nervures are usually traced in brownish ; this central area is usually larger and 

 more unsullied in the ^ than in the ? ; the borilering of the costal area is limited by 

 the subcostal nervure excepting that it ordinarily occupies also the bas.al third of the 

 subcostal interspace; the interior margin of the outer bordering is usually crenulate 

 and not so broad, approaching beyond the cell to within the width of an interspace 

 and sometimes only half an interspace from the outer border ; tlie inner border is very 

 broadly margined, even to the median nervure, although the medio-submediau inter- 

 space is often less deeply infuscated and is largely concealed by greenish tawny hairs. 

 Fringe as in fore wings. 



Beneatli pale. dull, greenish buff, the central portions, and on the fore wings the 

 costal area, tinged with tawny. Fore loings ; nhove the lower median nervule and occa- 

 sionally also below it the outer bordering of the upper surface is indistinctly repeated 

 in a dusky, pale green tint ; the median patches of the wing are also repeated indistinctly 

 in dusky shades, and between these and the outer bordering the wing is ratlier pale, 

 often, and especially in the ?, developing into an extra-mesial, irregular, pale band, 

 broadening and fading below; the medi.an nervules are usually faintly traced in brown- 

 ish, the inner margin as far as the submedian nervure is griseous, while the central 

 portion of the base within the median patches is blackish fuscous; the outer border of
