NYMPHALINAE: THE GENUS CHLORIPPE. 233 



the apical pair prolonged into slender but not very long spurs. Tarsi having tlie 

 basal joint nearly as long as all the rest together, the three following decreasing reg- 

 ularly in lengtii, the fifth as long as the second ; the tarsi are provided beneath with 

 four (the tcnnuial joint with only two) rows of short and slender small spines, the 

 apical ones of each joint a little longer than tlic others. Claws of moderate size, com- 

 pressed, rather slentler, strongly curved, finely pointed. Paronychia very slender, 

 delicate, tapering, slightly curved, nearly as long as the claws. Pnlvillus small, trans- 

 verse, very narrow, witli a small rounded projection in front. 



Male appendages of the abdomen : upper organ with the body pretty broadly 

 rounded laterally, scai'cely arched longitudinally ; hook depressed, more than half as 

 long as the body and nearly half as broad, separated from it by a broad sulcatiou, 

 constricted a little at the base and notched at the tip. Clasps gently and regularly 

 tumid, foi'raed of a thin vertical plate, directed upward as well as backward, about 

 two and one-half times as long as bi'oad, oval or broadly fusifoiMn, the lower border 

 rounded, the upper angulated, armed at the tip with a little liook. 



Egg. Sub^lolmlar, of nearly equal height and breadth, the l^ase rounded, except in 

 the llattoued middle half, the summit very broadly and regularly convex; sides from 

 base to micropyle rosette with nearly equal, not greatly elevated, nor strongly com- 

 pressed vertical ribs, 18-20 in number, connected by numerous very faint and delicate 

 cross lines. Micropyle rosette rather large, composed of numerous subequal, rather 

 regularly pentagonal or hexagonal cells, whose diameter toward the outside is about 

 the height of the quadrate cells beyond, but diminishes in approaching the centre. 



Caterpillar at birth. Head smooth and rounded, without tubercles. Body Avith 

 regularly distributed papillae, each giving rise to a simple delicate hair not longer than 

 the segments, the papillae arranged (so far as can be judged from Edwards's figures) 

 in the following manner : a subdorsal series anteriorly placed ; a supralateral placed 

 just behind the middle; an infralateral anteriorly placed, — all these with one to a seg- 

 ment in each roAV ; and a stigmatal series with two to a segment. 



Mature caterpillar. Head subquadrate, strongly appressed, slightly deeper below 

 than above, the summit crowned by a pair of strongly divergent, otherwise erect, 

 strong, coronal spines, no longer than the height of the head, furnished with many 

 stout and elongated radiating spinules, and the posterior flank of the cheeks with a 

 frill of simple, elongated, curving spines. Frontal triangle hardly twice a high as 

 basal breadth, scarcely reaching half way to summit. Ocelli six in number, five 

 arranged in a very shallow curve, tlie first four equidistant and appi'oximate, the 

 fourth mitlway between the first and fifth, the sixth posterior to the fourth, superior 

 to the fifth and equidistant from both, the connecting lines forming a right angle. 

 Body segments obscurely divided into four subsegments by slight plications, the 

 anterior being the longest, the second next, the third and fourth equal, and together 

 slightly longer than the first, all abundantly and subequally supplied with very irregu- 

 larly distributed, larger and smaller, minute, subconical or spherical papillae, slightly 

 more numerous along slender supralateral and infrastigmatal lines, the larger papillae 

 nearly half as large as the spiracles, and each furnished with a simple delicate hair as 

 long as itself. 



Chrysalis. Strongly compressed, being twice as high as broad, dorsally carinate, with 

 strongly arched abdomen, and a distinctly arched, but not greatly elevated mesonotum ; 

 anteriorly the dorsal carina terminates with the thorax, and is supplemented by a pair 

 of subdorsal carinae (as long as the space between their tips) which run from the tip 

 of the slender, trigonal, pointed, ocellar tubercles toward, but not to, the middle of the 

 mesonotum. The inner edge of the wing-cases is also carinate, and the lower surface 

 of the body flat, as if appressed to a flat surface in hanging, the wings not being at 

 all protuberant, and the surface, from below the basal wing tubercle to the cremaster, 

 forming a single straight line. Cremaster very remarkable, forming a flattened disk 

 on this same line, extending beyond tlie tip of the last segment proper as a depressed, 

 triangular, pointed protuberance, with strongly margined sides, its inferior surface 

 marked by two very long, parallel and approximate, but anterioi'ly divergent ridges,
