1346 THE BUTTERFLIES OF NEW ENGLAND. 



near the base, the basal three-fourths very broadly convex, the apical fourth curved a 

 little more strongly especially in the ? ; outer margin very broadly and slightly sinu- 

 ous, having a general direction at right angles to the apical part of the costal margin, 

 the angle rounded off, the inner margin straight, very slightly and broadly eniargi- 

 nate in the middle, the outer angle well rounded off. First superior branch of subcostal 

 nervure arising just beyond (61 : 15 J'), or just before (61 : 10 ? ) the middle of the 

 outer two-thirds of the upper margin of the cell, the second a little more (,J) or a 

 little less ($) than half way from this to the apex of the cell, the third at the apex, 

 and the fourth scarcely less ((J) or a little more (?) than one-third the distance from 

 the apex of the cell to the outer border ; cell a good deal more than half as long as the 

 wing and nearly three and a half times longer than broad. At the origin of its fourth 

 branch the median nervure is raised above the continuation of its basal half by rather 

 more than the width of the last median interspace at its base; cross vein connecting 

 median and submedian near the base directed straight downward until close to the 

 latter anil then curved outward. 



Hind wings with the costal margin greatly shouldered next the base, the angle 

 rounded off, beyond scarcely convex as far as the tip of the costal nervure, where it 

 begins to curve toward tlie outer border leaving no definite angle ; outer border con- 

 siderably crenulate, greatly produced in the median region, in the anterior half of the 

 wing curving quite regularly, fullest in the lower subcostal region in the ? , in the upper 

 subcostal region in the $ , but directed at a very broad angle with the costal margin and 

 at nearly as broad an angle with tlie posterior half of the border, which is slightly 

 concave, except in bearing at the tip of the upper median nervule a very long equal 

 expansion, rounded at the tip and fully four times as long as broad; jnst before the 

 middle of the medio-submedian interspace it suddenly recedes with a rounded angle 

 for a considerable distance and then resumes its former course; inner border narrowly 

 folded, a very little concave, the angle rounded off. Subcostal nervure nearly straight 

 between the bases of the first two nervules ; vein closing the cell slightly shorter than 

 that uniting the bases of the second and third median nervules. 



Fore femora as long as ( ? ) or much shorter than (^) the fore tarsi, the tibiae about 

 five-sixths the length of the tarsi ; middle femora and tarsi of equal length, the tibiae as 

 long as ( 9 ) or somewhat shorter than (jj) they ; the three principal parts of the hind 

 legs eitlier of nearly equal length, the femora a very little shorter ( ? ) ; or, increasing 

 rather regularly in length outward, the tarsi fully a third longer tlian the femora {$) ; 

 hind femora either equal to the fore femora and about flve-sevenths the length of the mid- 

 dle femora {$) ; or, equal to the middle femora and a little longer than the fore femora 

 ( 9 ) ; hind tibiae scarcely longer than the middle tibiae and a quarter (<?) or a half 

 (?) longer than the front tibiae ; middle and hind tarsi of about equal length and more 

 than a fifth longer than the front pair. Femora scarcely fringed with short, delicate 

 hairs. Tibiae armed beneath on either side with a row of rather infrequent, small and 

 rather slender spines ; on either side above with a double row of similar spines and at 

 tip with a pair of equal or almost equal, very long and very slender spines. First joint 

 of tarsi equal to the second, third and half the fourth together, the third and fourth 

 equal and slightly shorter than the second and fifth, which are equal; joints armed on 

 either side beneath with a row of very short and rather slender and frequent spines, 

 the apical ones of each joint and three or four scattered along the inner row of the 

 basal joint a little longer; above chanelled slightly along the inner side and there 

 devoid of scales, but still furnished with four rows of smaller, almost recumbent scales, 

 those on the outer side but vaguely traced ; claws very long and slender, compressed, 

 slightly but sharply heeled l)eneatli at the very base, the basal three-quarters of the 

 inner edge straight, the upper very broadly convex, the apical fourth tapering to a 

 delicate point and curved somewhat strongly downward; paronychia and pulvilli 

 wanting. 



Abdomen with the second segment of the male only a little longer than the first and 

 equal to the third; beyond, the segments decrease slightly in length, the middle of the 

 dorsum of the eighth developing a posterior hook as long as Itself, broadly expanding
