NYMPHALINAE: THE GENUS EUPHYDRYAS. 685 



rounded and pretty full in the upper two-thirds, almost ani^nlated in the $ , beyond 

 straight, in the $ scarcely receding near the anal ani^lo. Inner marijin slightly con- 

 vex on the powdered basal three-fourths, beyond excised and scarcely cmarginate, the 

 angle rounded ott". Precostal nervure directed straight upward, but close to the tip 

 bending rather abruptly outward. Second subcostal nervule originating but a short 

 distance beyond the first; cell open, but with remnants of the cross vein lying scarcely 

 beyond the second divarication of the median nervure. 



Fore legs long, cylindrical, in the male rather abundantly fringed, especially on the 

 outer side, but also above and a little on the inner side, with long, considerably spread- 

 ing hairs; tibiae two-fifths the length of the hind tibiae; tarsi either four-fifths {$) 

 or seven-eighths ($) the length of the tibiae; consisting either of two equal joints, 

 the last abruptly docked and armed at the tip with a short, central, slender spine, 

 nearly as long as the width of the apex of the tarsus, and apparently also with a pair 

 of lateral fleshy spiniform fingers, nearly as large as the spine {$); or of five joints, 

 the first nearly twice as long as the others together, the second occupying two-fifths 

 of the remainder and the others decreasing regularly in size; all but the last fur- 

 nished at the tip beneath with a pair of quite long and slender spines, those of the 

 first joint nearly recumbent, the others supported beyond by slender bristly spines, 

 seated upon the succeeding joint; the first joint is considerably stouter than the 

 others, and the three following ones supplied with central, lateral, delicate spines 

 beneath ( 5). Middle tibiae scarcely shorter than the hind tibiae, both furnished on 

 either side beneath with a row of quite long and slender, infrequent spines, branching 

 considerably, the apical ones developed as pretty long, slender, tapering spurs ; on 

 the inner side also are a few very small spines, mostly arranged in a single broken 

 row next the upper surface. First joint of tarsi scarcely equaling the rest together, 

 the three following decreasing regularly in size, the fifth fully equalling the second ; 

 furnished beneath with four rows of moderately frequent, short and slender spines, 

 the apical ones of each joint a very little longer than the others. Claws small, mod- 

 erately slender, curving considerably, finely pointed; paronychia double, the anterior 

 lobe nearly as long as the claw, not very slender, but little curved, tapering consider- 

 ably to a fine point; inferior lobe fully half as long, rather slender, equal, curving 

 inward ; pulvillus rather large, well rounded, broader than long. 



Abdomen : male appendages ; upper organ supplied apically with two short, pointed, 

 lateral processes at some distance apart, each bearing a minute subapical thorn ; 

 clasps small, stout, subquadrate, strongly convex, a stout, but not very large, inferior 

 process at the base and an interior, central, laminate, bifurcate tooth of considerable 

 size. 



Egg. Compact, subglobular, much taller than broad, the base broadly and consid- 

 erably rounded, broadest near the middle of the lower half, the sides tapering with 

 a slight curve, the summit less than half the size of the base, squarely docked, flat, 

 or slightly concave, furnished with a considerable number of faint, equidistant ribs, 

 running from the edge of the summit less than half way down the sides; surface 

 nearly smooth. Micropyle rosette occupying the whole summit of the egg with cells 

 of a larger size than usual, generally elongated and bounded by fine lines. 



Caterpillar at birth. Head well roiuided, broadest at about the middle, where it is 

 very slightly angulated, fully as broad as high, the crown of each hemisphere a very 

 little tumid, a very few rather short hairs. Body cylindrical, very slightly depressed, 

 the apical half tapering slightly, furnished with longitudinal rows of small, rounded 

 warts, one to a segment in each row, each wart giving rise to a moderately short, very 

 slender, tapering, delicately pointed, apparently naked, but in reality delicately spicu- 

 liferous hair; they are disposed as follows : a laterodorsal row in the centre of the seg- 

 ments, a lateral row at their posterior extremity, a suprastigmatal row again in the 

 centre, an uifrastigmatal row of warts smaller than the others on the posterior extrem- 

 ities of the segments, and a ventrostigmatal row on the anterior portion of the seg- 

 ments. On the thoracic segments all the warts are centrally placed. Legs long and 

 pretty slender, the terminal joint tapering but little, the claw pretty long, tapering,
