668 THE BUTTERFLIES OF NEW ENGLAND. 



base, beyond nearly straight, slightly convex ; the outer margin scarcely crenulate, 

 well and pretty regularly rounded, more regularly in the ^ than in the $ , the margin 

 being fuller next the completely rounded upper angle, while it is comparatively fuller 

 in the subcostal region iu the $ ; the loAver angle is abrupt but rounded ofl', and the 

 inner margin a little expanded, but not abruptly next the base, slightly convex on the 

 basal half, nearly straight and a very little excised on the apical half. Precostal ner- 

 vure directed straight upward, but not far from its tip bent abruptly and rather 

 strongly outward. Second subcostal nervule originating but a little beyond the first ; 

 cell open. 



Fore legs short, the members tumid, in the male thinly fringed with long, but little 

 raised hairs on the outer side; tibiae half (^) or a very little less than half ($) the 

 length of the hind tibiae; tarsi one-half the length of the tibiae ($) or of the same 

 length ($), either slender and with but slight indications of divisions and unarmed 

 (^) ; or distinctly composed of five joints, of which the first is tumid and somewhat 

 longer than the others collectively, they slender and diminishing regularly in size ; all 

 but the last furnished beneath with long and slender apical spines on a naked field, 

 the last two pair followed on the next joint by several bristle-like spines as support- 

 ers; the first and second joints have also a central subapical spine beneath (?). 

 Middle tibiae scarcely longer than tlie hind pair, armed on eitlier side beneath with a 

 row of very long and slender, not very frequent, somewhat spreading spines, the 

 apical ones developed as not very long, but slender, tapering spurs. First joint of 

 tarsi scarcely shorter than the others combined, tlie last scarcely shorter than the 

 second, the second, third and fonrtli diminishing in regular ratio; furnislied beneatli 

 with four rows of pretty long and very slender, frequent spines, the last of each joint 

 slightly longer than the others. Claws small, delicate, strongly falcate, finely pointed ; 

 paronychia double, the anterior lobe nearly as long as the claws, not greatly curved, 

 tapering considerably, the apex bluntly pointed, coarsely pectinate beneath; posterior 

 lobe short, moderately slender, curved iuAvard. Pulvillus not large, not much broader 

 than long, well rounded. 



Abdominal appendages of the male having the clasps stout, tumid, irregularly 

 and broadly oval, much longer than broad, bearing at the tip two strongly curv- 

 ing, flattened spines, appearing to originate from a separate piece soldered to the 

 upper extremity of the clasp; the lower of these spines curves inward, the upper 

 forward; in addition, arising from near the base of the latter is a similar spine curv- 

 ing over inward strongly. 



Egg. Barrel shaped, tapering above more than below, the broadest part below the 

 middle; the summit broad, saucer shaped, only slightly depressed, smooth and glis- 

 tening; the sides with numerous vertical ribs which are only slightly elevated and 

 Avhich extend from the bottom of the egg to the well defined edge of the saucer 

 where they abruptly end, more or less interrupted below the middle by the numerous, 

 but slight, rounded or polygonal depressions with which the egg is here studded. 



Caterpillar at birth. From notes taken by me, but which I am unable to verify, I 

 think the hairs of this stage of Cinclidia are arranged in laterodorsal, lateral and 

 stigmatal series, the lateral with two, the others M'ith one to a segment; but they are 

 somewhat differently disposed on tlie thoracic and abdominal segments. There is no 

 dorsal series, as in the later stages. 



Mature caterpillar. Head subquadrate but broadly rounded, broadest in the 

 upper part of the ocellar field, rather broader than high, the sides scarcely tapering 

 upwards, the summit broadly and but little produced exteriorly, considerably but 

 broadly and roundly excised above along the suture; the front appressed, almost flat, 

 the sutures a little impressed, the head slightly the deepest just below the middle, 

 covered above and on the sides, though scarcely on the front, with infrequent, moder- 

 ately large and broad, conical tubercles, emitting no hairs, but a few pretty long, curv- 

 ing hairs appear on the front as elsewhere, arising from exceedingly minute ■wartlets. 

 Antennae with the second joint exceedingly short, the third not greatly narrower, 

 more than half as long again as broad, the fourth minute. Ocelli six in number, five
