HESPERIDI: TlIK (iENUS EUDAMUS. 1381 



deep below, the front rcceilhig above to a well rounded siuninit, having a precipitous 

 posterior slope, the hintler edge of the head lioiiig tnineate; the surface Is more or 

 less nigulosc, and covered with a very tine, very short and exceedingly sparse pile; 

 ocelli six in number, four arranged in a strongly arcuate series with convexity for- 

 ward, subequidistant, the tlfth posterior to the third from the top and as distant 

 from it as the uppermost; the sixth, next the outer posterior base of the antennae, as 

 distant from the tiftli as the tlfth from the first; these three with the fourth at the 

 angles of a very elongated lozenge. 



Dorsal shield of the first thoracic segment conspicuous , occupying fully the posterior 

 half of the segment, longitudinally arched. Rest of the body very long ovate, largest at 

 thethlrdand fourth abdominal segments, taperingaboutci|ually toward either extremity, 

 the last segment broadly rounded and apically subtruncate ; abdominal segments divided 

 into a broad anterior section occupying fully one-third of the whole and the remainder 

 into four subequal sections of which the first is directly over the spiracles ; the surface 

 covered with exceedingly numerous, regularly distributed, raised points each bearing a 

 short tapering bristle; besides which there are numerous irregularly distributed conical 

 papillae higher than broad, occupying a space equal to half a dozen of the others, each 

 bearing a short , hyaline, tapering, apically open but not expanded hair ; there is also a low , 

 infrastigmatal series of very minute, perfectly circular, crateriform annuli, not a twen- 

 tieth as large as the spiracles, and scarcely in advance of them, on all the abdominal seg- 

 ments, on the first abdominal segment placed directly beneath the spiracle and distant 

 from it by its own length; in a similar position, halfway between the spiracles and the 

 legs, a pair of these annuli are found upon the first thoracic segment. Legs with the 

 basal fleshy joints very stout, the chitinous portion appressed, slender, tapering; the 

 hook strongly bent and finely pointed ; prolegs stout, blunt, with an apical, complete 

 circlet of strongly arcuate hooks, arranged in triple rows, the hooks shaped very mucll 

 as the claws of the legs but bent less strongly, and beyond rather than before the 

 middle, regularly tapering, strongly compressed. 



Chrysalis. Head and prothorax separated by a distinct and rather deep sulcation 

 from the mesothorax. forming a nearly rectangular mass with rounded corners, twice 

 as broati as long and as broad anteriorly as posteriorly ; front gently and slightly pro- 

 tuberant on the middle third and on all the protuberant portions very sparsely and 

 finely pilose ; mesothorax tumid, a little longer than broad, rather angulate at the 

 basal wing prominences, which show a distinct but slight double superior and inferior 

 elevation; beyond this the body narrows very slightly to the abdomen, then gradually 

 increases again to a width, at the third abdominal segment, slightly greater than 

 that at the liasal wing prominences, beyond which it tapers with some rapidity 

 over three or four segments, then much more I'apidly to a conical tip; viewed from 

 the side the dorsum of the mesothorax is gently arched, with a more rapid descent 

 behind than in front, beyond which the dorsal line ii straight over the fixed ab- 

 dominal joints and then slopes gradually to the cremaster; the front is roundly 

 angulate beneath, the ventral slope as far as the extremity of the wing very 

 gentle, scarcely more arcuate posteriorly than in front, tlie wings being in the very 

 slightest degree protuberant. Prothoracic spiracles exceedingly large, auriculate, 

 semilunar, with protuberant flaring posterior lip, their outer extremity surpassing the 

 width of the prothorax ; guarded posteriorly by a broad semi-annulus of dense, ex- 

 cessively short bristles and protected in front by a sparser collection of similar 

 bristles upon the prothorax. The position of the mandibles marked by a scarcely 

 perceptible callosity bearing a few bristles. Posterior legs reaching as far as the 

 antennae, excepting for the width of the tip of the latter; these extending as far as 

 the middle of second abdominal segment, in front of which the thorax slopes rapidly 

 to the slightly narrower prothorax. Moveable segments of the abdomen with a pre- 

 median, distinct, blunt carina, encircling the whole body, its posterior face more 

 rapidly abrupt than the anterior. Preanal button supporting the inferior base of the 

 cremaster consisting of a horseshoe-shaped, but somewhat angulate ridge most promi- 

 nent at the angles, from which, but disconnected with them, diverge dull lateroventral
