PAPILIONLNAE : THE GENUS JASONIADES. 1281 



mencement, is aftenvards uniform ami (iimiiiislies more rapidfj- on tlie last four joints 

 to a bluntly conical apex ; viewed from above, the increase and diminution are very 

 similar in character and extent, giving the club a fusiform appearance, the tip bluntly 

 pointed ; the club is twice as broad as the also compressed stalli, and eight times as 

 long as broad ; uniler edge serrate on a side view and very broadly and sliallowly chan- 

 nelled on the outer side, and very distinctly, rather narrowly and deeply grooved on 

 the middle of the inner side. Palpi very minute, rather slender, reaching the middle 

 of the front of the eye and hea^■ily fringed with very long, erect liairs. 



Prothoracic lobes obsolete. Patagia rather small, scarcely arched or tumid, curved 

 .slightly outward, throe times as long as broad, the basal half equal, the apical taper- 

 ing very slightly to a very bluntly pointed apex. 



Fore wings (40: 10) scarcely twice as long as broad, the costal border very slightly 

 convex previous to the apical sixth, where it curves downward considerably ; outer bor- 

 der straight, rounded off a very little at either extremity, and liaving a general direc- 

 tion at an angle of about 40° with the middle of the costal margin ; inner margin 

 scarcely concave, rounded off at tlie tip. First superior subcostal branch arising just 

 before the middle of the outer half of the cell; second midway between this and the 

 apex of tlie cell ; third at the apex; and fourth at one-third the distance from the 

 apex to the outer border. Cell considerably more than half as long as the wing and 

 three and one-half times longer than broad. At the origin of the fourth median 

 branch the main vein is raised above the continuation of its basal half by the width of 

 the last median interspace at its base. Cross vein connecting the median and submedian 

 veins near the base directed outward in passing downward. 



Hind wings with the costal mai-gin considerably and roundly shouldered next the 

 base, beyond nearly straight, slightly convex, curving downward to meet the outer 

 border at the apex, which is well rounded off; outer margin strongly crenulate, the 

 lower half greatly produced, the upper lialf broadly rounded, more so in the ^ than in 

 tlie 1^ , and fullest though rather more rounded at tlie angle in the former, at the upper 

 median nervule prolonged to a very long and nearly equal tail, a little expanded inte- 

 riorly at the tip, the apex well rounded, four or Ave times longer than broad ; posterior 

 to the tail the border recedes slightly and has an emargiuate augle and a slightly con- 

 cave inner border, quite as in Papilio. Subcostal nervure nearly straight between 

 the bases of the first and second nervures ; vein closing the cell slightly shorter than 

 the distance between the bases of the second and third median nervules. 



Fore femora and tarsi of about equal length and a third longer than the tibiae ; mid- 

 dle tarsi but little longer tlian the tibiae and about four-fifths tlie length of the femora; 

 hind femora, tibiae and tarsi of very nearly equal length ; femora differing but slightly 

 in length, the middle pair longest; hind tibiae a fifth longer than the middle tibiae or 

 three-fifths longer than the front pair; fore and middle tarsi of nearly equal length (in 

 the female shorter in the middle legs) and about five-sixths the length of the hind 

 tarsi. Femora with a moderately long brush of thin, spreading hairs beneath. Tibiae 

 furnished on either side beneath with a row of not very frequent, short, and moder- 

 ately slender spines ; just within the inner row a few other scattered spines, and on the 

 upper portion of either side a double row of frequent but otherwise similar spines; at 

 the apex beneath a pair of very long and slender spines, the inner a little the longer. 

 First joint of tarsi scarcely equalling the length of the three succeeding joints taken 

 together; these scarcely differing in size, the fifth .slightly longer than any of them; 

 all armed beneath on eitlier side witli a row of rather infrequent, very short, moder- 

 ately slender and almost curving spines, the apical spines of each joint no longer, 

 scarcely stouter, but a little more curved than the others ; above with four equidistant 

 rows of scarcely more frequent, smaller and slenderer, nearly recumbent spines ; 

 claws long and very slender, compressed, strongly and largely heeled below at the 

 base, the basal half nearly equal and nearly straight, the apical half tapering to a deli- 

 cate point, and considerably and regularly curved ; paronychia and pulvilli absent. 



Hook of eighth abdominal segment of the male expanding considerably basewards, 

 the part beyond rather stout, its extremity subspatulate. Valves large, irregularly
