1740 THE BUTTERFLIES OF NEW ENGLAND. 



Thorax covered above with brownish olivaceous tawny hairs, on the prothoras more 

 like the upper surface of the head, witli many intormiugled black scales; beneath 

 with pale lemon-gray hairs. Femora dark slate brown, the upper and outer surface 

 flecked or wholly covered with silvery gray ; tibiae pale slate brown externally, 

 witliin dusky at base, beyond pale yellowish; leaf-like appendage of fore tibiae pale, 

 glistening, yellowish brown; tarsi pale, glistening buff; spurs the same, tipped with 

 blackish red; spines and claws reddish luteous. Pad blackish. 



Wings above ricli dark brown, the fore wings occasionally tinged slightly, especially 

 toward the base and along the costal border, witli ferrugineo-tawny or luteo-tawny and 

 the hind wings often furnished, especially on the lower half of the disc, with dull, dark, 

 olivaceo-tawny hairs. Both wings with a faint darker line at the outer margin. Fore 

 wings ot $ with uo other markings excepting the discal stigma (43:13) which is incon- 

 spicuous, nearly straight, composed of two nearly equal, ovate, black edged, blackish 

 brown patches, rounded basally, pointed apically, the outer slightly above the inner, 

 scarcely larger and parallel to it, about four times as long as broad; its apex scarcely 

 reaches the last divarication of tlie median, while the base of the inner is followed 

 above by a minute patch of velvety black compact hairs, touching the submedian ner- 

 vure a little beyond the middle of its basal two-thirds ; the stigma is followed in the 

 lower median and medio-submedian interspaces Ijy a very inconspicuous area of 

 slightly raised ijrownish scales usually tinged with tawny, rather wider than the 

 stigma, divided into two confluent patches by the lower median nervule, each extend- 

 ing furthest toward the border at its upper onter limit on the nervule above it. Fore 

 wing of $ with three subcostal, cloudy whitish spots often obsolete or obsolescent, 

 seldom distinct enough to be longitudinal, arranged at right angles to the costal 

 margin scarcely beyond the middle of its outer half ; and two larger, though small and 

 usually distinct, white, median spots, the upper round, or when larger subtriangular, 

 close to the base of the upper median interspace, the lower usually transversely cres- 

 centic, sometimes transverse and straight in the lower median interspace, below a 

 point midway between the upper spot and the last divarication of the median nervure ; 

 the two spots fall in a line drawn from the apex of the wing to the middle of the 

 inner border; in rare instances, there is a faint, pale, cloudy streak on the submedian 

 nervure below the lower spot ; and the outer edges of the subcostal and median spots 

 are then united by an equally indistinct, arcuate series of cloudy spots, its convexity 

 outward. Fringe of both wings scarcely paler than the ground color of the wing, 

 growing paler outwardly. 



Beneath dark brown, not so rich as above, the apex of the fore wings and the whole 

 of the hind wings tinged slightly with olivaceous (^) or purplish ( ? ). Fore wings 

 in the male slightly paled in the median interspaces just beyond the reverse of the 

 discal stigma ; in the female the markings of the upper surface are repeated. Fringe 

 much as above. Hind wings with an extra-mesial, arcuate, obscure, very narrow, 

 pale band, parallel to the outer border, in the middle or shortly before the middle of 

 the outer two-thirds of the wing from the upper subcostal to the submedian nervure ; 

 it is composed of broken spots, often nearly imperceptible in the $ , never distinctly 

 deflned, even in the $ . Fringe as above. 



Abdomen blackish brown, covered above at base with dark olivaceous hairs, on the 

 sides with very dull, olivaceo-tawny scales, beneath grayish with mingled whitish and 

 dusky scales. Male appendages (37 : 23) having the upper organ with the centrum 

 pretty strongly arched on the horizontal portion, the hook three times longer than 

 broad, similar in form and relation to those of L. bimacula; lateral arms forming a 

 single equal lamina, connate throughout, rounded at the tip, appressed to the hooks, 

 somewhat longer than they and slightly upturned at the apex. Clasps scarcely more 

 than twice as long as broad, the upper margin with a rounded basal lobe, but scarcely 

 any sign of an apical one excepting a transverse incision before the middle of the 

 clasp ; apex produced posteriorly as a sabre-like expansion, finely angled, but not drawn 

 to a point; and superiorly as a large, broad, rounded, incurved lobe, directed slightly 

 forward.
