188 THE BUTTERFLIES OF NEW EXGLAXD. 



bearing at the tip a pair of very minute, short, siiglitly curving-, tapering spines( ? ) ; 

 or, of one joint only, of which the apical fifth is obscurely and partially marked off, 

 and the apical half of the same conical and bearing an exceedingly minute and short 

 apical pin ($); fore legs wholly unarmed, excepting by the clothing of their long hairs, 

 not profuse, and diverging only a little, more distinct in the male than in the female. 

 Middle tibiae five-sixths the length of the hind tibiae. Tibiae furnished beneath with 

 lateral rows of moderately long and very slender, not very distant spines, the apical 

 ones developing into long and slender spurs, scarcely tapering until near the apex. 

 First joint of the tarsi equalling four-sevenths of the Avhole member, the second, 

 third and fourth diminishing a little and gradually in length, the fifth equalling the 

 second; the joints supplied beneath with very numerous, pretty long and very slender 

 spines; claws very delicate, strongly compressed and curved, pretty sharply pointed; 

 pulvillus minute, transverse, semicircular; paronychia broad and nearly circular at 

 base, beyond produced to a long, slender, curving, compressed, nearly equal apex. 



Male abdominal appendages : upper organ rather slender, the centrum somewhat com- 

 pressed, laterally triangular, gently arched above, constricted slightly at the extreme 

 base of the hook, which is a little arcuate, with an independent curve at the level of 

 the upper surface of the centrum, a little longer than it, pointed at tip; sides of the 

 centrum furnished at their upper extremity, close upon the base of the hook, with a 

 single, slender, tapering, straight, backward directed appendage. Clasps rather stout, 

 bullate, shorter than the upper organ, about three times as long as broad, the apical 

 half narrowing, the tip rounded, curved imvard and armed with a cluster of minute 

 teeth. 



Egg. Of a slightly depressed spheroidal shape, broader than high, perfectly flat at 

 base, Avell-rounded above, the sides inflated with a very regular, full curve, fullest in 

 the middle of the lower two-thirds. Surface apparently smooth, but covered with 

 very delicate small cells, separated by slender, obscure, apparently sunken bands. 

 Micropyle formed of minute, slightly elongate, generally hexagonal cells, their longest 

 diameter pointing toward the centre, increasing a little in size outwardly. 



Caterpillar at birth. Head of equal height and breadth, broadest below, the sides 

 scarcely tapering upward in the lower half, and in the middle of each side a large 

 tubercle ; summit of each side occupied in front by a very large, rounded, broad, but 

 not greatly elevated, warty tubercle. Surface nearly smooth, minutely rugulose. Body 

 cylindrical ; terminal segment tapering considerably on the apical half and considera- 

 bly excised posteriorly in the middle, leaving a pair of sharply pointed, but very short, 

 backward directed proj ections. The body is furnished with a number of tubercles bearing 

 peculiar appendages, as follows : a subdorsal row, one to a segment, placed anteriorly ; 

 a laterodorsal, one to a segment, placed posteriorly ; a laterostigmatal, one to a seg- 

 ment, placed centrally; and an infrastigmatal row, two to a segment, a posterior, 

 higher, and an anterior, lower one, the latter bearing appendages like those of the 

 rest of the body, the former emitting a single tapering hair of the length of the usual 

 appendages ; these (86 : 38) are straight, rather short bristles of uniform size nearly 

 to the tip, Avhere they are delicately clubbed and squarely docked. Legs rather short, 

 thick, the last segment rounded off, scarcely tapering, armed at tip with a rather short 

 and slender, tapering claw, straight, excepting close to the base, where it is bent at 

 right angles. Spiracles circular, pedicelled, the pedicle somewhat constricted just be- 

 fore the extremity. 



Mature caterpillar. Head very full, unusually deep, the summit of either half ex- 

 cessively produced upward and, at maturity, a very little forward, into a slender, reg- 

 ularly tapering, straight, conical horn, as long as the head, the outer sides of which 

 are in almost exact continuation of the sides of the head, and are parallel to each 

 other; but in the earlier stages there is a slight broad constriction near the base, and 

 it is only after two moultings that the horns become at all conspicuous ; front of the 

 head a little appressed, though curved from above downward, below the base of the 

 horns, particularly in the earlier stages; apart from the horns the head is broader than 

 high, of exactly the breadth of the first thoracic segment, broadest near the ocelli,
