NYMPIIALIXAK: TIIK (;EXUS AGLAIS. 415 



Egg. Hroacl ovate, of about (mhuiI heiirht and width, broadly rounded beneatli, still 

 more so above, narrowini;; slightly in i)as>ing upward, but api)arently of ec^ual width 

 from the constantly increasiui? Ijrcadth of tiie ribs in passin.a; from the base to the 

 summit; these are few in nund)er, well arched at the summit, after the style of Va- 

 nessa, I)ut are not so hij^h ; they arc stronuly compressed and prominent; cross ribs 

 slifjht but distinct, especially abf)ve, leaving between them spaces about four times as 

 long as broad in the nuddlc of the egg. 



Caterpillar at birth. Head smooth and well rounded, l)roadest in the middle of the 

 upper half where it is very inconspicuously angulate, a little broader than high, slightly 

 sulcate above, and furnished with a few scattered hairs. Body uniform, tapering only 

 on the last two or three segments, armed with longitudinal rows of hairs like those of 

 Envanessa but somewhat shorter and arranged in similar rows, excepting that those of 

 the subdorsal series are more anteriorly placed, those of the supralateral decidedly 

 posterior, and tlie infrastigmatal distinctly in advance of the spiracles. 



Mature caterpillar. Head not very large, pretty well rounded, the sides broadly 

 rounded, broadest in the middle; the summit of either half pretty broadly rounded, 

 very slightly elevated, the suture between a very little depressed; the whole front is 

 snbai^pressed, hardly deeper below than above, covered with pretty frequent, small and 

 minute, short conical tubercles, all the latter, and some of the former emitting pretty 

 long hairs; triangle fully half as high again as broad, extending fully half way to the 

 summit. Antennae with the second joint not half so long as broad, the third three- 

 quarters the diameter of the second and half as long again as broad, cylindrical, 

 sciuarcly docked, emitting a moderately long hair; fourth joint not noticeable. Ocelli 

 as in Envanessa. Lal:)rum small, half as broad again as long, well rounded, prett}' deeplj' 

 excised in the miildle. Mandibles very small, moderately stout, the edge straight, 

 coarsely and slightly denticulate. Maxillary palpi small; first and second joints of 

 nearly equal diameter; third slightly smaller, fully half as long again as broad, rounded 

 at apex; fourth minute, knob-like. Spinneret rather long, slender, curved, tapering. 



Body cylindrical, largest in the middle of the abdomen, tapering more anteriorly than 

 posteriorly, armed with pretty long, moderately stout spines, each one tapering regu- 

 larly, docked at the tip, and bearing a bristle-like thorn, scarcely smaller than a con- 

 tinuation of the spine would have been, finely pointed and about one-third the length 

 of the si)ine itself; these spines bear numerous larger and smaller cylindrical tu- 

 bercles, from the lai'ger of which, generally three or four in number, arise long acicular 

 thorns, longer than the apical thorn of the spine, and divergent at an angle from the 

 spine: fi'om the smaller ones, Avhich are much more numerous, shorter and much more 

 delicate needles take their rise. The spines are arranged in longitudinal roAvs, one to 

 a segment in each row, as follows : a dorsal series, inserted anteriorlj' on the second to 

 the eighth abdominal segments ; a laterodorsal series, placed a little in advance of the 

 middle, directly over the spiracles, on the first to the eighth abdominal segments; a 

 supralateral series, placed centrally on the second and third thoracic segments; the 

 spines of the last two series are slightly longer than the others ; a laterostigmatal 

 series, placed similarly to the row above, on all the abdominal segments; a suprastig- 

 matal series, placed centrally, on the second and third thoracic segments; and an in- 

 frastigmatal series, placed centrally, on the first to the eighth abdominal segments. 

 The body is supplied pretty abundantly with minute conical warts, some exceedingly 

 minute, each emitting a hair, proportioned in length to the size of the wart, the largest 

 more than half as long as the spines, and on the posterior pai'ts of the segments 

 arranged in transverse rows ; the smaller ones with no regularity of disposition ; first 

 segment with a transverse anterior series of the largest ones. Spiracles leather small 

 obovatc, nearly twice as broad as long. Legs and prolegs as in Envanessa. 



Chrysalis. VicAved from above the prothorax and head scarcely taper to the tips of 

 the ocellar projections, which are conical, bluntly pointed and have their inner edges 

 inclined at a right angle to each other, the space between them squarely docked ; on a 

 side view they are directetl straight forward, a little protuberant at base, their lower 

 edge considerably inclined to the under surface of the chrysalis, their upper nearly
