NYMPHALID.VE : ARGYNNIDJ. 1803 



rnpted stripe, composed of moderately narrow black bars or liinules in all the interspaces 

 above the siibraedian nervure, at very different distances from the outer margin, the 

 general direction of the whole band being twice bent at a right angle , at the upper 

 median and lower median nervules; in the middle of the outer half of the wing a 

 transverse, almost straight series of round black spots, largest in the median nervules, 

 becoming longitudinal streaks in the uppermost subcostal interspaces; and finally, be- 

 tween these last and the mesial band, the subcostal nervures are marked in black and 

 accompanied by a powdery bar, depending from but not touching the costal margin ; 

 outer margin followed within, at the distance of half an interspace, by a black-brown 

 stripe connected with the margin by powdery bars at the nervules, and preceded by a 

 series of delicately formed black lunules in all the interspaces, wholly independent 

 of each other and enclosing between them and the pre-marginal stripe faint orange 

 spots, which are not wholly enclosed ; fringe brown, interrupted with white or luteous. 

 Hind wings excepting for their deeper and richer tone, wholly resembling those of A. 

 aphrodite, and excepting, also, that the interrupted bent band of the lunules found in 

 aphrodite is replaced here by transverse bars of smaller extent. 



Beneath, the /ore wings do not differ from those of A. aphrodite, excepting in the 

 markings being less heavy, nor do ,the markings of the hind wings differ so far as re- 

 gards the position, number, relations and form of the silvery spots; but the ground 

 color is of a nearly uniform cinnamoneous, in the outer half of the wing more or less 

 bathed with dull fulvous orange, excepting in the near vicinity of the spots; there is, 

 herefore, in the outer half of the wing, between the two rows of silvery spots, a nar- 

 row stripe of lighter color, as in A. aphrodite, and, as there, the color is much the 

 same as that bordering the margin of the wing; but the contrast is here very slight 

 between this lighter band and the parts surrounding it, so as to make it far less con- 

 spicuous. Expanse of wings, 75-77 mm. 



I give here Mr. Edwards's descriptions of the early stages, with such modiflcations 

 of the phraseology as are necessary. 



Egg. Conoidal, truncated, not so broad at base as in S. idalia, the sides less rounded; 

 depressed at summit, marked vertically by about eighteen prominent, slightly wavy 

 ribs, half of which extend from base to summit and form around the latter a serrated 

 rim ; the remainder end irregularly at two-thirds to three-quarters distance from base, 

 sometimes squarely, at one of the striae, but usually curved towards and unite with 

 the long ribs ; between each pair of ribs are equidistant, transverse striae. Shape of 

 A. aphrodite and B. myrina, being more slender, narrower at base, and less convex on 

 sides than the other large species of this genus. In Mrs. Peart's magnified drawings 

 the eggs of A. alcestis and B. myrina are indistinguishable from each other. 



Caterpillar. First stage. Head a little broader than any segment, rounded, slightly 

 bilobed, somewhat pilose, color dark brown. Body cylindrical, thickest anteriorly, 

 tapering backward, the dorsum sloping considerably; color brownish green, translu- 

 cent; each segment, from the second thoracic to the eighth abdominal, marked by 

 eight rows of tubercular dark spots, six of them placed on dorsum and upper part of 

 sides, each spot giving out a long, black, clubbed hair, which is curved forward; 

 the other two rows are beneath spiracles (one on each side), and consist of much 

 smaller spots, each with two or three short hairs; still lower down, in a line over the 

 legs, are points with fine hairs ; on the first thoracic segment is a blackish dorsal patch , 

 and on either side are two small spots, and all these are furnished with hairs; on the 

 ninth abdominal segment is a row of four small spots, and behind it one of two. 

 Length, 2 mm. 



Second stage. Head subcordate, black, with many short, black hairs. Body thickest 

 in middle; color yellow green, on dorsum mottled with brown, especially at bases of 

 spines; six longitudinal rows of large spines, besides a row of very small spines along 

 base of body, over the feet; the laterodorsal series begins at the first thoracic and 

 runs to the ninth abdominal segment, one upon each segment ; the two rows on the sides 

 begin at the first abdominal segment, and of these the laterostigmatal series stops at 

 the eighth abdominal segment, the lower continuing to the next, always but one on
