708 THE BUTTERFLIES OF NEW ENGLAND. 



half of the sides, especially below. Basal joint of antennae pretty broad, mammiform, 

 the second, a short annulus, the third cylindrical, neai'ly twice as long as broad, 

 abruptly docked and bearing at the upper part of the tip a fourth, similar, but exces- 

 sively small joint; the extremity also bears, at the edge, a very long and two very 

 short and delicate bristles. Ocelli Ave in number, four in a ratlier broad curve (its 

 convexity facing forAvard and slightly upward) at nearly equal distances apart, the 

 first and second, counting from above, being more widely separated than the others, 

 the fifth behind the fourth, so that a line drawn from the third to the fifth through 

 the fourth would form a right angle, the distance between the fourth and fifth a 

 little less than that between the fourth and second ; fifth a little smaller than the 

 others, which are equal. Labrum of moderate size, nearly twice as broad as long, its 

 edges rounded, deeply excised in the middle and angulated. Mandibles pretty large 

 but not very stout, broad, the edge straight, distinctly 4- or 5-denticulate. Maxillary 

 palpi four-jointed, the joints successively smaller, the first two very broad and short, 

 the third cylindrical, equal, less than tAvice as long as broad, abruptly docked, the 

 fourth similar but much smaller and shorter. Spinneret tumid, pretty large, conical, 

 four-jointed, the third joint minute, the last long and very slender, spiuiform, com- 

 pressed, equal viewed from above, tapering when seen from the side. 



Body large, fieshy, plump, transversely wrinkled and folded, C3'lindrical, of nearly 

 equal size but tapering a little forward on the thoracic segments, the first segment 

 even slightly smaller than the head, the last abdominal segment with a broad, very 

 low, subconical, fleshy, mediodorsal tubercle or swelling; armed on the second thora- 

 cic and eighth abdominal segments Avith a pair of very long and slender, fleshy, scab- 

 rous, nearly or quite cylindrical, supralateral filaments, equal beyond the base and 

 bluntly pointed, the anterior ones slightly appressed; they increase greatly in length 

 during development and when fully grown the anterior pair exceed the posterior sev- 

 eral times. Segments divided very inconspicuously into a very long anterior and two 

 short, equal, posterior sections, the anterior twice as long as the others together and 

 with a feeble sign of a median subdivision. Whole body densely scabrous with mi- 

 nute granulations, occasionally interrupted by quite as minute a wart giving rise to a 

 fine hair scarcely longer than itself ; tliese Avarts are arranged in transverse roAvs, four 

 or five roAvs to a segment, but Avith no great regularity. Legs short, rather slender, 

 conical, the last joint very slender, tapering, the claAv very small, tapering, a little 

 curved; prolegs rather short, the basal joint broad, plump, the second cylindrical, 

 broader than long, scarcely tapering, its apical outer edge Avith a fringe of not very 

 frequent, rather long, curving hairs ; hooklets very minute, slender, considerably 

 curved, numerous, — from fifty to eightj^ — arranged in a close triple roAV, forming the 

 longer half of an oval. Spiracles large, obovate, Avith a slender, raised, exterior rim. 



Chrysalis. Body smooth, Avith scarcely impressed, excessively minute, short, fre- 

 quent and transverse lines ; largest just behind the middle of the posterior half of 

 the third abdominal segment, Avhere it is furnished, across the entire back, Avitli a 

 close roAV of Ioav, blunt, smooth, slightly appressed, conical papillae; behind tliis the 

 abdomen is almost hemispherical, but conically produced a little toward the cremaster; 

 in front, it narroAVS considerably on the back to the hinder edge of the mesothorax ; 

 viewed from above, tlie chrysalis narroAvs a little to the middle of the first abdominal 

 segment and then passes in a straight line to the basal Aving tubercle ; thorax Avith a 

 broad anterior curve ; vieAved from above it narroAVS rapidly beyond the basal Aving 

 tubercle as far as the ocellar prominences, betAveeu Avhich it is broadly rounded, 

 almost docked; angle betAveen the front and summit of head Avell rounded ; ocellar 

 tubercles conical, not very high but broad, situated just beneath the basal joint of the 

 antennae, rounded at tip; basal wing tubercles scarcely prominent, rounded, sur- 

 mounted by a small, smooth, rounded Avart; a very slight longitudinally oval eleva- 

 tion at the upper tip of the cell of the Avings ; a someAvhat similar but smaller and 

 narrower elevation on either side of the mesothorax somewhat in advance of the 

 angle made at the base of the wing; and still another slightly more elevated, subdor- 

 sal pair near the hinder extremity of the mesothorax ; anterior base of the cremaster
