NYMPllALINAE : THE GENUS PIIYCIODES. 623 



Abdoinen slender, the upper organ of the male appendages a little depressed, conical, 

 '•l)li(|uely docked. Clasps stout, longitudinal, much more tlian twice as long as broad, 

 tlie basp.l half ratiicr tumid, the apical half tapering to a pointed, down-curved tip, 

 incurveil only at tlie extremity; interior tooth arcuate, aculiform, curving first inward, 

 then bac]<ward and tlirougliout a little upward, nearly as long as the tapering part of 

 the clasp. 



Egg. Pyriform, truncate above, broadest much below the middle, but little higher 

 than broad, tlie under surface broadly rounded. Lower iialf pitted, thimble-like, with 

 polygonal cells, upper half furnished with numerous slight vertical elevations extend- 

 ing to the tlat summit; the latter covered again with hexagonal cells. 



Caterpillar at birth. Head broadest above, broader than high, tapering rapidly 

 beneatli, the hemispheres well and independently rounded, tlie frontal triangle about 

 three-fifths the height of tlie head, the whole smooth, with scattered simple hairs. 

 Body narrower than the head, cylindrical, equal, furnished with slender hairs, seated on 

 simple papillae arrangcMl on each side as follows : a laterodorsal series, slightly in 

 advance of the middle, on the thoracic and abdominal segments; a lateral series, on 

 the anterior part of the thoracic and the posterior part of the abdominal segments ; 

 a suprastigmatal series, situated mesially or slightly in advance of the middle, on 

 the abdominal segments only; and an infrastigmatal series, one to a segment, poste- 

 riorly situated on both thoracic and abdominal segments, besides another on the 

 abdominal segments, anteriorly situated, and a little lower tlian the other. The hairs 

 are slender, tapering, spiculiferous, directed in diflerent ways on the different series of 

 papillae. 



Mature caterpillai. Head well rounded, verj' similar in form to that of Brenthis, 

 broadest at the upper part of the ocellar field, scarcely tapering above, the summit 

 broadly rounded, a very little full exteriorly, the suture between scarcely depressed, 

 deepest in the middle, the front flattened a little; triangle slender, reaching about 

 half way up the front, fully half as high again as broad; head covered rather sparsely 

 on the sides and summit, scarcely at all in front, with minute tubercles emitting mod- 

 erately long hairs, one tubercle, at the anterior outer limit of the summit of either 

 side, a little larger than the others. Antennae with the second joint as long as broad, 

 the third of the same diameter and rather more than half as long again as broad, 

 the fourth very minute. Ocelli six in numl^er, five in rather a strong curve, its con- 

 vexity forward and a little downward, the middle three at equal distances from each 

 other; the others a little furtlier removed from them, the sixth behind the others, at 

 equal distances from the first (or uppermost) and fourth with which it forms a 

 right angle; the third, fourth and fifth are large and very prominent ; the others a 

 little smaller and much less prominent, the second slightly more so than the others. 

 Labrum pretty large and long, longitudinally ridged, the front border broadly, roundly, 

 but not very deeply, excised. Mandibles long and broad, but not very stout, the 

 edge straight, denticulate, with half a dozen small, triangular, sharply pointed teeth. 

 Maxillary palpi rather stout, short, the joints about equal in length and each consid- 

 erably slenderer than the preceding joint. Spinneret exceedingly slender, not very 

 long. 



Body armed witli tubercular spines arranged in longitudinal rows ; they are stout, 

 conical, somewhat higher than broad, bluntly pointed at tip, covered abundantly with 

 minute wartlets emitting each a rather delicate, tapering, needle-like thorn, nearly as 

 long as the whole spine and directed at au angle upward ; they are arranged as 

 follows: — a dorsal series, anteriorly placed on the first to ninth abdominal seg- 

 ments; a laterodorsal. mesially placed on second to third thoracic, and a little in 

 advance of the middle on the first to eighth abdominal segments ; a suprastigmatal 

 antemedian on the first to tenth abdominal segments ; and an infrastigmatal antero- 

 median from the second thoracic to tlie tenth abdominal segments. The first thoracic 

 segment has no tubercles but only many long hairs. Legs rather long, moderately 

 slender, appressed, tapering considerably, the claws small, compressed, strongly- 

 heeled at base, beyond very slender and nearly equal, curving gently.
