1394 THE BUTTERFLIES OF NEW ENGL.AJNU. 



as many times longer than the basal joint, the apical joint very small, cylindrico-ovate, 

 twice as long as broad, and half as long as the breadth of the middle joint, directed 

 a little forwards. Protlioracic lobes almost entirely aborted, scarcely discernible; 

 patagja mncli as in Eiulamus. 



Fore wing (41 : 2) long, triangular, rather more than twice as long as broad; costal 

 margin nearly straight, but gently and almost etiually sloping at the two extremities, 

 the apex sub-rectangular; outer margin bent at tlie independent vein at a very broad 

 angle, nearly straight above and below it, scarcely pi'otuberpnt at the submedian nervure ; 

 inner margin straight, barely and very broadly excised in the middle, bent at a general 

 angle with the outer margin of about 115". Costal margin thickened for nearly half 

 its length; costal nervure terminating directly above the lower extremity of the cell; 

 superior subcostal nervules hugging the nervure in their proximal portion ; the first 

 arising opposite the base of the second median nervure, at three-fifths the distance 

 from the base to the apex of the cell ; the others as in Eudamus, the apex of the wing 

 being continued between the nervure proper and its last superior branch; inferior 

 subcostal nervule as in Eudamus ; first median nervule oi'iginating very close to the 

 base of the wing at about one-fourth the distance to the origin of the second branch; 

 cross vein closing the cell obsolete excepting at its extremities, slightly less oblique 

 than the margin of the wing, striking the median nervure directly beneath the origin 

 of the third superior subcostal nervule; about midway between this and the base of 

 the second median nervule is the origin of an otherwise obsolete reversed shoot, ex- 

 tending to the centre of the cell; cell about seven times as long as broad, and nearly 

 five-sevenths the length of the wing; internal nervure as in Eudamus, excepting tliat 

 the tip of the vein becomes difl'used and lost before reaching the submedian. 



Hind wing subtriangular; costal margin very strongly arcuate at the base, beyond 

 very gently arcuate ; the outer margin very full in the subcostal region, excepting for 

 the submedian lobe considerably and pretty regularly arcuate ; the lobe dentiform, 

 broader than long, well rounded on the inner side, excised at the base on its outer 

 side; inner margin gently and faintly concave. Costal, precostal and subcostal 

 nervures as in Eudamus ; space inclosed between the costal and subcostal at base 

 smaller, and the two veins completely amalgamated at their point of separation ; sub- 

 costal forking at a little less than one-third way to tlie margin and connected with the 

 median nervure by an obsolete arcuate cross vein, less than half as far beyond the sec- 

 ond divarication of the median as that is beyond the first; sutjmedian nervure straight, 

 hardly separated from the nervure on either side of it ; internal nervure almost mar- 

 ginal. 



The scales enclosed in the costal fold of the male include a very long and slender 

 spatula and a rod-like bristle with apical flagellum. 



Legs 2, 3, 1 ; tufted as in Eudamus, but the upper surface of the hind tibiae much 

 more thinly ; femora 2, 1, 3, tibiae 27^, 1, tarsi 3, 2, 1 ; fore coxae very long and most 

 profusely furnished exteriorly with long hairs; fore and hind femora of equal 

 length, middle femora nearly one-third as long again; fore femora with a row of 

 profuse long hairs along the posterior inferior edge, shortening apically. Fore 

 tibiae two-thirds as long as fore femora, and more than half as long as middle 

 and hind tibiae; these equal, the middle pair a little shorter than the middle femora, 

 the hind tibiae one-fourth longer than the hind femora. Leaf-like appendage long 

 and slender, originating in the middle of the apical four-fifths of the tibia, sur- 

 passing its extremity a little, fully four times as long as broad, a little arcuate, 

 especially on its apical half, which tapers regularly to a point; middle and hind tibiae 

 with an apical pair of long spurs beneath, the hind tibiae with a similar but shorter 

 pair in the middle of their apical four-fifths. Tarsal joints 1, 2, 3, 4,5; fore 

 tarsi two-thirds as long as the middle, a little less than two-thirds as long as the 

 hind tarsi ; hind tarsi only a little longer than the middle pair ; all with a triple row of 

 slender spines beneath, longer and more erect on the middle and hind tarsi, the apical 

 ones of each joint on all the legs considerably longer tlian the, others; basal joint as 

 long as the rest of the joints together on tlie liind and middle legs, a little longer than
