1564 THE BUTTERFLIES OF NEW ENGLAND. 



the last joint fully as broad as the stalk; the middle joints of the stalk a little more 

 than twice as long as broad. Palpi two and one-fourth times longer than the eye, 

 rather slender, heavily but loosely clothed with long hairs on all but the protruding 

 apical joint ; basal joint very small, globose, as broad as long, and one-third the length 

 of the middle joint; middle joint large, tumid, cylindrical, slightly arcuate, well 

 rounded at either end, more broadly at base tlian at tip, three and one-half times 

 longer tliau broad ; apical joint inclined a little forward, exceedingly minute, though 

 apparently several times longer than it is, from the long hairs which follow the direc- 

 tion of its lengtli, nearly twice as long as broad, tapering bluntly, rounded at tip, its 

 length scarcely equ.alling half the breadth of the middle joint. 



J'rothoracic lobes small, appressed, lamellate; when viewed from the front nearly as 

 long as the shorter diameter of the eye, fully half as long again as high, subtriangular, 

 the inner and inferior sides straight, the other rather broadly arcuate. Patagia 

 large, the posterior lobe longer than the basal portion, and half its width, slightly 

 arcuate, nearly equal, but tapering toward the rounded tip ; the whole nearly as long 

 as the breadth of the head. 



Fore wing (42 : 2) twice as long as broad, the lower outer angle falling but little 

 beyond the middle of the costal margin; costal margin ratlier strongly conve.x at the 

 base, beyond faintly concave; outer margin well rounded above, straight below, the 

 apex somewhat pointed. The costal uervure terminating a very little beyond the 

 middle of the costal margin ; the subcostal moderately distant from the costal mar- 

 gin, its second nervule arising at the middle of the wing; cell a little more than 

 three-fifths the length of the wing; first branch of the median arising midway 

 between the second and the base of the wing, and very far before the origin of the 

 first subcostal branch; internal uervure brief, straight. 



Hind wing elongate, triangular, less than half as long again as broad ; costal margin 

 strongly lobed at the base, beyond straight; outer margin strongly and pretty regu- 

 larly rounded above, straight below, the au.al angle well rounded. Median nervules 

 widely separated at base, the first nervule arising much nearer the base than the sub- 

 costal fork. 



Legs 2 3, 1. All the femora fringed beneath with somewhat spreading hairs, which de- 

 crease in length regularly from base to tip of joint; on the middle and hind femora the 

 basal hairs are half as long as the femora itself ; base of the tibiae furnished above with 

 very few, distant, long hairs. Femora 2, 1,3; tibiae 2, 3, 1 ; tarsi 3, 2, 1 ; fore femora 

 of the same length as the hind pair and three-fourths the length of the middle femora; 

 fore tibiae about four-fifths the leugth of the fore femora and two-thirds the length of 

 the middle tibiae, which are scarcely longer than the hind pair; leaf -like appendage 

 of the fore tiljia greatly reduced, consisting of a slender, straight, tapering, painted 

 process, not twice as long as the breadth of the joint, but four times as long as broad, 

 attached to the middle of the outer two-thirds of the joint, and scarcely surpassing 

 half the distance thence to the tip ; other tibiae armed at the tip with a pair of long and 

 very slender spines ; hind tibiae without the secondary pair of spurs but with a double 

 series of a few, very distant, minute, delicate spines beneath. Tarsal joints 1, 2, 5, 

 3, 4, terminal scarcely longer than the third joint, bnt on the fore legs twice as long as 

 the fourth ; fore tarsi about two-thirds the length of the middle and a little more than 

 half as long as the hind tarsi, scarcely shorter than the hind tibiae, — all furnished be- 

 neath with a triple row of minute delicate spines, the apical ones of each joint but little 

 longer than the others ; basal joint very nearly as long as the rest together, the second 

 fully two-fifths the length of the basal joint. Claws small and pretty delicate, rather 

 strongly curved, tapering. Pad moderate, transverse. Paronychia very slender, thread- 

 like, half as long as the claw, nearly straight. 



Upper organ of male abdominal appendages very small and slender; hooks longitu- 

 dinal, conical, adjacent throughout ; lateral arms forming an inferior sheath-like lamina. 

 Clasps pretty large and broad, twice aslong as broad, nearly equal, the tip very broadly 

 rounded, an apical tooth arising from the lower margin, scarcely separate from the 

 blade.
