1758 THE BUTTERFLIES OF XEW ENGLAND. 



slightly longer than Ijroail, slightly appresseil, with a not very lar;;e, tumid expansion 

 interiorly at the tip, middle joint largo, bullate, ovate, iu the middle as broad as the 

 basal joint, increasing in size slightly from base to tip, broadly rounded at either ex- 

 tremity, a little arcuate, aljout twice as long as the greatest breadth, apical joint 

 seated on the middle of the extremity of the preceding, minute, cylindrical, bluntly 

 pointed, straight, about three times as long as broad, but only about half as long as 

 the breadth of the middle joint. 



Prothoracic lobes as in Calpodes, three-fourths the length of the shorter diameter of 

 the eye. Patagia pretty large, about four-flfths as long as the width of the head, the 

 posterior lobe half as broad and considerably longer than the base, straight, tapering 

 a very little and rounded at the tip. 



Fore wing (42 : 16) considerably less than twice as long as broad, the lower outer 

 angle falling well outside the middle of the costal margin ; the costal margin distinctly 

 convex at the base, beyond nearly straight, apically declivent ; outer margin gently 

 convex, slightly bent in the middle, the apex somewhat pointed, especially in the male_ 

 Costal nervure terminating on the costal margin at three-fifths the distance from the 

 base; subcostal tolerably near the costal margin, its second nervule arising scarcely 

 before the middle of the wing; cell two-thirds the length of the wing, moderately 

 slender, broadest in the middle of the apical half; first median nervule arising nearer 

 the second than the base of the wing, the second below the second subcostal nervule; 

 internal nervure short, curving upward to meet the submedian. 



Hind wing scarcely longer than broad, the basal lobe pretty large; the costal mar- 

 gin straight, of about equal length with the inner margin ; the upper half of the outer 

 margin strongly convex, below nearly straight, well rounded at the anal angle and 

 above it. Median nervure first forking some distance beyond the subcostal, nearly 

 approximated to the second forking. 



Legs 2, 3, 1. Hind and middle femora furnished beneath with a fringe of ver}' long 

 hairs decreasing in length toward the tip where they vanish; the fore femora similarly 

 provided but only with short hairs ; hind tibiae furnished above with a thin fringe of 

 inconspicuous hairs. Femora 2, 1, 3; tibiae 2, 3, 1; tarsi 3,2, 1. Fore femora 

 slightly longer than tlie hind pair, tliree-fonrths the length of the middle femora. 

 Fore tibiae only three-fifths the length of the fore femora, which are but little shorter 

 than the middle and hind tibiae. Leaf-like appendage of the fore tibiae very slender, 

 attached a little before the middle of the basal two-thirds, extending considerably 

 beyond the joint but pretty strongly arcuate tliroughout, pointed at the tip but other- 

 wise equal, seven or eight times as long as broad. Other tibiae furnished at tip with 

 a pair of very long and slender, unequal spurs and the hind tibiae with a secondary 

 pair, exactly similar, situated in the middle of the apical three-fourths of the tibia; 

 middle and hind tibiae furni.shed at the sides with spines which on the inside are 

 distant and irregularly scattered, on the outside are \cry few in number arranged in a 

 regular row. Tarsal joints 1, 2, 3, 4, 5. Fore tarsi about four-fifths the length of the 

 middle tarsi which are scarcely shorter that the hind tarsi, all furnished beneath with 

 three rows of rather long spines, the apical ones of each joint somewhat longer than 

 the others; basal joint equal in length to the second, third and fourth together; 

 second scarcely half as long as the first. Claws pretty small, compressed, strongly 

 arcuate, a little bent in the middle. Pad rather small, transverse. Paronychia 

 bilobed, the upper lobe laminate, compressed, subfalcate, nearly twice as long as 

 broad, reaching to tip of claw, gently tapering, bluntly pointed; the lower lobe thread- 

 like, very slender, half as long as the claw. 



Abdominal appendages of male having the upper organ moderately large, pretty 

 broad, gently arched; hook a little arched, depressed above, stout, triangular, taper- 

 ing regularly and rapidly to a very blunt, downcurved point ; lateral arms inconspicu- 

 ous, forming a very slight, triangular lamina beneath the middle of the hook. Clasps 

 as long as the upper organ, about twice as long as broad, nearly equal and scarcely 

 convex, well rounded at the tip, almost unarmed.
