PAPILIONINAE: THE GENUS HERACLIDES. 1329 



Fore femora as loiij; as ( $ ; or somewhat shorter than ( $ ) the fore tarsi ; the tibiae 

 scarcely (<? ) or fully (?) three-fourths the length of the femora; middle femora a 

 trirte shorter (,J) or a trille louger (?) than the middle tarsi; the tibiae as long as 

 (?) or a little shorter than {$) they; the hind tibiae and tarsi of equal length and 

 considerably longer tlian tlie femora (<J), or the tarsi, tibiae and femora are succes- 

 sively smaller to a considerable degree ( ? ) ; middle and hind tarsi of al)0Ut equal 

 length and fully a fourth longer than the fore tarsi. Femora scaled oidy ; tibiae 

 armed on all sides witli rather infrequent, small, slender, nearly recumbent spines, 

 nearly all of wliicli, and especially those at the lower outer margin, may be assigned 

 to detlnite longitudinal rows, of which, besides those upon the lower surface, there 

 are five or six series, the inner surface only being free. First joint of the tarsi fully 

 equ.alling all the rest together, the remainder subequal, the second being longest and 

 the fourth shortest; joints armed on either side beneath with a double row of closely 

 crowiled, not very long, slender, subrecumbent spines; both the inner and outer sides 

 narrowly channelled and smooth, but the whole upper surface and upper angle of the 

 sides bristling with minute spines, lilie those upon the tibiae, arranged for the mo.st 

 part in four or live rows, of which the two outer are more distinctly ranged and have 

 stouter spines. Claws long and moderately slender, compressed slightly, and rather 

 coarsely heeled beneath at the very base; beyond the under edge straight as far as the 

 curved and delicate pointed apex ; paronychia and pulvilli wanting. 



Second abdominal segment of the male no longer than the first ; beyond, the seg- 

 ments decrease slightly and somewhat regularly in length, the middle of the dorsum 

 of the eighth segment developing a spine nearly as long as itself, narrowly triangu- 

 lar, roundly truncate at tip as seen from above, obliquely truncate as seen from below, 

 and not at all curved downward. Valves triangular, with well rounded angles, the 

 narrowest angle below anteriorly, the liroadest portion, viewed longitudinally, at the 

 upper base, of equal length and breadth, armed within by an inferior, arcuate, toothed 

 lamina. 



Egg. Subglobular, about a fifth broader than high, well rounded, with no depression 

 at summit, the base broadly and roundly truncate, scarcely so broad as the height. 

 Surface uniformly roughened by the secretion of the mother. 



Caterpillar at birth. Head large, subquadrate, broader than high, as broad as the 

 body of the first thoracic segment, well rounded, smooth, covered sparsely with 

 bristly, tapering hairs of equal length (more in number than represented on our plate) ; 

 the triangle more than half as high as the head. Body suljquadrate, tapering distinctly 

 from in front backward on the anterior, scarcely at all on the posterior half, slightly 

 moniliform ; the first thoracic segment, independent of its tubercles, somewhat larger 

 than the others, all furnished with several series of very large, mammiform, fleshy 

 prominences, hemispherical in front, conical behind, each studded with papillae 

 bearing pretty long, minutely clubbed or rather apically flaring, straight, tapering 

 bristles, and arranged in definite order; viz. : a supralateral series on each of the seg- 

 ments, generally central, becoming posterior on the first thoracic segment; these de- 

 crease slightly in size from in front backward, but again increase on the posterior 

 segments to a size rather larger than at first, and here are twice as high as broad ; a 

 suprastigmatal series on all the segments, with numerous bristles, in front considerably 

 larger than the first series, particularly those of the first thoracic segment, which, 

 laterally expanding, blunt and stout, nearly double the width of the segment, and are 

 nearly as broad as its length. There is, besides, a subdorsal series of single similar 

 hairs on slight papillae, centrally placed on all the segments, more widely separated on 

 the first thoracic segments ; and an infrastigmatal series crowded again with bristles. 

 From specimens mounted in glycerine. 



Mature caterpillar. Head of moderate size, appressed, globular, somewhat broader 

 than high, subtruncate and very broadly rounded below, well arched above, distinctly 

 notched between the hemispheres, the face nearly flat. Inner triangle scarcely higher 

 than broad, frontal suture rather deeply impressed; surface smooth and glistening 

 with very sparsely scattered, short, downcurved hairs. Ocelli six In number, five in a
