most conspicuous are ii pair of very Iouj; ones, one a little within the niicUUo of cither 

 heniisphcrc, at the level of the top of the triangle, four small but unciiual, ineiiuidls- 

 tant ones, a little outside the whole length of the sides of the frontal IriauKle, ami a 

 pair of small ones across the middle of the same. Body slender, slightly nioiiiliforni, 

 due in large part to a snhstiginatal expansion, on which the papillae of that point are 

 placed. Papillae conical, higher than broad, arranged, besides the transverse series of 

 the first thoracic segment, in an anterior, laterodorsal series on all the other segments; 

 a snpralateral series anteriorly placed on the thoracic, posteriorly on the abdominal 

 segments ; an interior, infralateral series on all the segments ; and an infrastigmatal 

 series, two to a segment, centrally and posteriorly placed on the abdominal, the latter 

 almost stlgniatal. one and central on the thoracic segments. Hairs straight, long, 

 erect, very delicately tapering, slightly expanded and open at the tip. Segments 

 divided into a large anterior and four equal, smaller, transverse sections. 



Mature caterpillar. Mead of the normal f(irm, three-quarters the breadth of the 

 body, studded very regularly with minute papillae, bearing erect and forward directed, 

 short, tapering hairs. Triangle more than half as high as the head, slender, more 

 than twice as high as broad. Ocelli five in number; four subequidistant in a gently 

 curving, vertical row, the fifth posterior, with the first and third forming a nearly 

 equilateral triangle. The mandibles massive, chisel-edged. Antennae nnnsually 

 small, the bristle very long. 



Body very slender, about seven times as long as broad, equal or scarcely tapering 

 behind the llfth abdominal segment, the last segment more rapidly to a truncate, 

 broadly eniarglnate tip. Segments divided by transverse incisions into six subseg- 

 ments, of which the second to fourth are subequal, the first half as large again as 

 either of these, the sixth smallest, all furnished with a large number of minute, short, 

 conical papillae, mostly arranged in a single transverse row on the narrower snb- 

 segments, but with scarcely any regularity whatever on the first subsegment; a few 

 regularly disposed in longitudinal series; on the first section of each segment a latere 

 dorsal, and on the fourth a lateral series of papillae largerthan the others, rounded coni. 

 cal broader than high, and bearing hairs twice a« long as the others, about as long as the 

 longest subsegments, minutely expanded at the apex, and supporting globules. Spiracles 

 long, oval, small and lenticular. Legs and prolegs short, the front pair of legs ranch 

 shorter than the others, so far as the fleshy basal joints are concerned. 



Chrysalis. In general the body Is much slenderer than in Eurymns ; viewed from 

 above, it is bell-shaped in front of the basal wing tubercles, the apex produced to a 

 moderately long, conical point, the distance from the extreme point to the basal wing 

 tubercles being about the width of the body ; the sides of the bell are most convex at 

 the ocellar ribbon, but the sinuate course of either side is but slightly removed from 

 a straight line. Behind the basal wing tubercles, where the body Is broadly augulate, 

 the body is equal as far as the end of the wing cases; beyond this, very gently and 

 regularly conical to the tip of the cremaster, which is truncate and roundly eniargl- 

 nate. Viewed laterally the body is more irregular and, excepting for the inferior expan- 

 sion of the wings which adds to the height of the body by two-thirds, quite straight. 

 The head and the prothorax have an independent curve of their own, being subglobu- 

 lar and apically somewhat constricted at the base of the frontal tubercle. The 

 mesothorax is gently arched, and Interrupts the very broad curve which otherwise 

 would continue from the back of the head to the tail. The inferior expansion of 

 the wing cases is midway In character between Callidryas and Euryraus, and beyond 

 them the ventral line is a continuous broad curve to the base of the cremaster, which 

 viewed laterally. Is slender, twice as long as broad, equal. There is a slight, dorsal 

 carlnation over the thoracic joints, the two lateral surfaces being inclined to each 

 other at scarcely more than a right angle, the carina rounded ; a similar carina, but at 

 an angle of 105°, follows the sides of the body from the basal wing tubercle to the 

 extremity of the wing cases. The tongue cases terminate just beyond the tips of the 

 antennae, which reach the lowest portion of the swollen wing cases. Abdomen 

 slightly depressed above, with an obscure, rounded carina in continuation of that
