1576 THE BUTTERFLIES ()!• NEW ENGLAND. 



loosely compacted, curving scales and hairs, ■which are rather abruptly cut off at the 

 tip of the second joint, beyond which the apical joint, clothed only witli recurabeut hairs 

 projects ; basal joint rather small, tumid, somewhat cup-shaped, the apical portion con- 

 siderably produced anteriorly, as long as broad, nearly half as long as the second joint ; 

 middle joint ovoid, scarcely twice as long as broad, a little arcuate, more broadly at 

 base than at tip ; the apical joint long, slender, straight, perfectly cylindrical or very 

 slightly conical, the tip bluntly pointed, fully three-fourths the length of the middle 

 joint, and about five times as long as broad. 



Prothoracic lobes moderately large, appressed, laminate; viewed from the front 

 semilunate, the base nearly straight, not twice so long as high, and about as long as 

 the longer diameter of the eye. Patagia pretty large, the posterior lobe longer than 

 the base, fully half as broad as it, scarcely tapering, broadly rounded at the tip, the 

 whole nearly as long as the breadth of the head. 



Fore wing (42 : 4) considerably less than twice as long as broad; the lower outer 

 angle falling but little beyond the middle of the costal margin; costal margin well 

 rounded at base, but beyond quite straight; the outer margin regularly and consider- 

 ably convex, the tip not at all produced. Costal nervure terminating in the middle of 

 the costal margin; subcostal nervure moderately distant from the margin, the third 

 nervule arising at the middle of the wing; cell three-fifths the length of the wing, 

 almost equally broad in the whole apical half ; first median nervule arising a little 

 more than half way from the base to the second and at considerable distance before 

 the origin of the first subcostal branch ; internal nervure straight, brief. 



Hind wing shaped in general much as in Pampliila, rather more prominent apically 

 in the subcostal region; only one-fourth longer than broad. Subcostal and median 

 nervures first forking at nearly equal distances from the base and far before the 

 middle of the wing ; the second median nervule arising at about the middle. 



Legs 2, 3, 1. All the femora furnished beneath with a slightly compressed fringe of 

 hairs, which decrease a little in length from the base toward the tip and are longer on 

 the middle and hind femora than on the fore pair; hind tibiae furnished above with a 

 few long hairs. Femora 2, 1, 3; tibiae 2, 3, 1 ; tarsi 2, 3, 1. Fore femora slightly 

 longer than the hind and nearly as long as the middle femora. Fore tibiae less than 

 two-thirds the lengllh of the hind femora, which are scarcely shorter than the middle 

 tibiae and of about the length of the hind tibiae. Leaf-like appendage of the fore 

 tibiae small, slender, about four times. as long as broad, largest just beyond the base, 

 slightly tapering and pointed, originating in the middle of the apical four-fifths and 

 surpassing the extremity of the tibia but a little; other tibiae furnished at tip with a 

 pair of long and slender spurs, the hinder femora with a secondary, exactly similar 

 pair on the middle of the apical four-fifths of tlie joint. Tarsal joints 1, 2, 3, 4, 5, the 

 terminal slightly longer than the penultimate on the fore legs ; fore tarsi four-fifths 

 the length of the hind tarsi, which are scarcely shorter than the middle ones ; all with 

 a triple series of delicate spines beneath, the apical ones of each joint much longer than 

 the others; basal joint as long as the second, third and fourth united, a little longer 

 on the fore legs ; second nearly half as long as basal joint. Claws small and deli- 

 cate, bent strongly in the middle, tapering. Pad moderately large. Paronychia 

 slender, lanceolate, as large as the apical half of the claw, straight. 



Upper organ of male abdominal appendages small, compact, directed straight back- 

 ward, reaching to the middle of the distal half of the clasps, of about equal breadth 

 and height, twice as long as broad; lateral arms fuUj' as stout as the double hook and 

 like it extended horizontally. Clasps stout, scarcely convex, subquadrate, twice as 

 long as broad, the lower posterior angle rounded, the upper one slightly pointed. 



Egg. Rather low, broadest at the base, broadly and regularly rounded, not flat- 

 tened above; surface covered by very faint, delicate, raised lines, enclosing pretty 

 regular, polygonal cells. Micropyle marked with a most irregular set of multitudi- 

 nous, delicate, raised lines. 



Caterpillar at birth. Head much broader and very much higher than any part of 

 the Ijody, rounded, sul)triaugular, pyramidal, faintly notched above, with an impressed
