784 THE BUTTERFLIES OF NEW ENGLAND. 



ajjain as the abdomen, composed of tliirty-two joints, of which twelve form the cyliu- 

 drical, depressed clul), which is very gradually thickened, less than twice the breadth 

 of the stalk, about five times as long as broad, terminating in a very blnntly rounded 

 apex, in which three or four joints participate. Palpi very small, slight and short, not 

 more than equalling the length of the eye, the last joint not half the length of the 

 penultimate, all the joints but the last clothed beneath with a mass of long, projecting 

 scales, accompanied l)y a few long or scale-like hairs; the last joint partakes of the 

 same character to a very slight degree. 



Patagia long but not very narrow, arched slightly and somewhat tumid, the outer 

 border a little hollowed near the middle, leaving the posterior lobe — or the apical half 

 of the whole piece — about three-quarters the width of the base and equal, the apes 

 broadly rounded. 



Fore wings (39 : 10) considerably more than half as long again as broad, the costal 

 margin very slightly curved at base and tip, nearly straight along the middle, the 

 apical angle slightly less than a right angle, scarcely rounded, sometimes subfalcate; 

 outer margin nearly straight, scarcely rounded above the middle of the lower median 

 interspace, below that receding a very little, the inner border straight, the outer angle 

 scarcely rounded. Costal nervure terminating a very little before the tip of the cell ; 

 subcostal nervure with three superior branches, the third forking somewhat beyond 

 the tip of the cell; internal nervure short and running into the submedian close to the 

 base. 



Hind wings with the costal margin abruptly shouldered and slightly plicated at the 

 base, beyond straight, the apical portion curving a little; outer border pretty welj 

 rounded, especially above, the upper angle rather abrupt but rounded off a little, the 

 inner border slightly convex at first, the apical four-fifths slightly excised, the outer 

 angle rather abrupt but rounded offa little. Precostal nervure very feeble, running only 

 from the bending of the costal nervure half way to the margin, in the direction of the 

 basal part of the costal nervure. Cell half the length of the wing, and three and one- 

 half times longer than broad. Submodiau nervure terminating on the outer border, near 

 the anal angle; internal nervure termiaatiug a little beyond the middle of the inner 

 margin. 



Fore legs long, slender and cylindrical (?), or exceedingly short and minute, but 

 comparatively stout, and aborted ( (J ) ; clothed like the other legs ( ? ) , or abundantly 

 furnished with long, recumbent scales and hairs, the trochanter attached to the tip of 

 the coxa ( J) ; fore tibiae three-flfths (?) or one-fourth (J") the length of the hind 

 tibiae ; fore tarsi more than f our-flfths ( ? ) , or about two-fifths ( ^ ) the length of the 

 tibiae; either consisting of a single, rather stout joint, rounded at the tip, and, like the 

 tibiae, entirely without armature ( J ) , or agreeing almost entirely in character with the 

 Other legs, although the ternii\ial joint is unsealed (but apically armed like the others), 

 and the spines are almost entirely absent from the whole tarsus, although the spurs are 

 very well developed ( ? ). Middle tibiae a little longer than the hind pair, armed with 

 but very few scattered minute spines, and furnished at tip with a pair of pretty short, 

 rather slender spurs, clothed with scales at their base. First joint of tarsi nearly 

 equal to the three following joints combined, while they diminish in regular ratio, the 

 fifth equalling the third ; furnished beneath with quite long and slender, not very fre- 

 quent spines, mostly confined to an outer row on either side, the apical spines of each 

 joint longer than the others, and a little curving; claws very small and pretty slender, 

 compressed, tapering, finely pointed, rather strongly and regularly curved : paronychia 

 double, each lobe as long as the claw, equal, curving a little, the upper tapering to a 

 fine point, and running close beside the claw, the lower equal and blunt-tipped ; pul- 

 villus very small, circular, sessile. 



Male abdominal appendages with the lateral alations of the upper organ united 

 above by about half their length, leaving a slender notch between them ; distal half of 

 the elbowed inferior arm arcuate, curving upward, reaching the rounded hind border 

 of the alation. Clasps with the basal half buUate, the outer slender and cylindrical, 

 the basal superior finger half as long as the clasps, very slender, aculeate, setose.
