824 THE BUTTERFLIES OF NEW ENGLAND. 



median iicrvules more or less slightly ami roundly iiroduced. Inner border rather 

 stron-rly and regularly rounded, just before the tip considerably and roundly cniargl- 

 nate, leaving a rounded lobe at the tip, directed inward. Sul)niedian nervure ter- 

 ininatinj^ on tlie outer border, just beyond the anal angle ; internal nervure terminating 

 just beyond the middle of the inner border. 



.■Vndroconia ril)bon-like, neai'ly equal throughout, with truncate apex, rounded at the 

 angles, the base slightly lobed and tlie stem very short. 



Fore tibiae about llve-sLxths the length of the hind tibiae, the tarsi equalling or 

 exceeding the tibiae In length; the last tarsal joint either resembles the same part in 

 tlie other legs ( ? ) ; or It Is small, tapering, curved and bears at its tip only a p.air of 

 nearly straight spines, the continuation of the row at the sides and is covered above 

 with very short and close hairs {S ) \ otherwise, and excepting that in both sexes the 

 tibial spurs are naked, these legs agree with tiie others. Femora ratlicr thinly (fore 

 femora tliickly) fringed with very long hairs, especially in the male. Middle tibiae 

 scarcely or not at all exceeding the hind tibiae in length, armed at the tip with a pair 

 of rather long spurs, clothed with scales nearly to the tip. First joint of tarsi equal 

 to the rest together (that of the hind leg tumid In the male), the others nearly equal, 

 the second and fifth largest and equal, armed profusely on eitlier side beneath with 

 rather long, not very slender spines, the apical one on either side of each joint a little 

 longer than the others; under surface of all the joints but the Iwsal devoid of scales; 

 claws small, compressed, strongly bent, with a curve at the middle, tapering, finely 

 pointed ; paronychia simple, nearly as long as the claw, broad and heavy, nearly equal ; 

 puhillus minute, projecting. 



Male abdominal appendages : upper organ rather large, but the alations rather 

 small, separated, as viewed above, by a deep notch which is scarcely pointed at the 

 extreme base ; neai'ly circular, furnished with strongly recurved lateral arms which 

 scarcely taper excepting at the finely pointed tip ; clasps nearly straight, conical, rather 

 rapidly and regularly tapering to a very finely drawn point, their lower edges sub- 

 connate nearly throughout. 



Egg. Very depressed, echlnold-shaped, as broad at summit as at base, studded pro- 

 fusely with prominent tubercles, each connected by six raised ridges to the neighbor- 

 ing prominences, disposed with considerable regularity in rows, but confused above, 

 and with cells of lesser size. Micropyle rosette sunken but very little, rather large, 

 composed of nearly uniform cells divided by slightly raised lines. 



Caterpillar at birth. Head pretty well rounded, broadest and scarcely angular 

 at the middle of the upper two-thirds, slightly broader than high. Body largest on 

 the thorax, nearly equal on the abdomen as far as the posterior third, where It tapers 

 to a rounded tip; flattened beneath a great deal, above flattened or hollowed a very 

 little, the sides apparently sloping or even hollowed, the lower margin laterally pro- 

 duced; abdomen furnished with a laterodorsal series of very elevated slender warts, 

 nearly uniform in thickness, two on each segment, emitting very long, erect hairs, 

 curving pretty strongly, the convexity forwards, tapering and very minutely splcu- 

 liferous, giving the hair a frosted appearance under the lens; In the same series, im- 

 mediately below. Is an anteriorly placed small wart, one on each segment, bearing a 

 backward directed stout hair, rather short, equal or a very little larger at apex that at 

 base, the apex rounded and the apical half minutely splcullferous. On the second and 

 third tlioracic segments all these hair-bearing warts become more and more distant 

 from each other and are placed side by side Instead of in a line ; and on the second 

 segment there Is also a similar subdorsal pair. In addition, on the swollen basal 

 fold of the body, there is another compound ventrostlgmatal series of similar but 

 not quite so elevated warts, bearing straight, tapering, smooth, laterally directed 

 hairs; tliere Is flrst a row of shorter hairs placed anteriorly, one to each segment; 

 next and very close to it a row of hairs as long as the dorsal ones, one to a segment, 

 placed centrally, and close to it a row of long hairs, two to each segment placed at 

 equal distances from the edges of the segments ; these are continued thickly all around 

 the edge of the last abdominal segment. Besides tlie hair-bearing warts there is a
