PAPILIONIDAE : PAPILIONLNAE. l849 



and without hairs ; instead of a complete and uniform ring there is a thicliening of the 

 yellow above and below the eye-spot, and the ends are narrowed, so that the appearance 

 is much like that of eye-lids. Length, 9 mm. One larva differed from all the rest, be- 

 ing uniform light, yellow brown, the white area on the seventh and eighth abdominal 

 segments yellowish. 



Fourth stage. Head as before, but greenish yellow. Body with same shape and 

 general color, the anterior segments a little darker, and their surfaces tjuely and thickly, 

 but indistinctly, dotted green; the middle segments lighter colored and distinctly dot- 

 ted green ; the side bands salmon color, the last segments a redder salmon ; ninth ab- 

 dominal segment white above base at extremity, along base of body, with and a little 

 above the spiracles, a white, macular band; on dorsum of ninth abdominal segment 

 two small, conical, white processes (none on the preceding) ; on dorsum of first ab- 

 dominal segment are two abbreviated bars of red lilac, one on each side, in the latero- 

 dorsal row, and on the second to sixth abdominal segments is a small, rounded, lilac 

 spot on each in same row ; on the side of the fourth to si.xth, one similar spot to each ; 

 on second thoracic to second abdominal segments low, rounded knobs as at previous 

 stage ; below the basal ridge is a small, indistinct, blue-lilac spot on each segment from 

 the second to seventh abdominal segments ; the ocellus as at previous stage, the buff 

 ring now open at anterior side. Length. 20 mm. 



Towards the last of this stage the brown area has a green tinge, and the green dots 

 become quite distinct and the side bands are greenish; the circlet of the eye-spot 

 changes to red-buff. Later the top of the anterior segments became olive green, the 

 dorsum after the first abdominal segment light green, edged down the sides by dark 

 green; the side band pale green, as are the last segments ; under side pale, greenish 

 brown ; the lilac spots unchanged ; the spots l)elow spiracles blue. 



Last stage. Head subovoid, bilobed, granulated, with a diUl gloss ; color olive green. 

 Body cylindrical, the second thoracic to first abdominal segments much thickened, 

 arched dorsally, then tapering to last; color dull, velvety green, on second and third 

 thoracic and first, eiglith and nintli abdominal segments nearly solid, but a little specked 

 with lighter green ; the other segments light and dark green in fine markings ; the basal 

 ridge whitish green ; under this is a fine black line from the second thoracic to eighth 

 abdominal segments, and on the second to seventh abdominal is a subtriangular blue 

 spot in black, edging on each segment just below the line; the first thoracic segment 

 has a narrow, yellow ridge in front, nearly flat on top, the curves rounded ; ou anterior 

 side of this and next it is a black, subdorsal dash on either side; behind the ridge is a 

 black, rough, or shagreened narrow band; the scent-organs light, yellow-brown; on 

 the side of the last thoracic segment is a black ocellus, upon which rises a rounded, 

 vitreous, black process, the circlet orange red, having a black stripe within its anterior 

 edge, and a blue spot on its upper outer side ; ou the first to seventh abdominal segments 

 are four rows of small, blue-lilac spots, each in fine black ring, two of the rows being 

 laterodorsal, two lateral ; on the eighth abdominal segment only the two laterodorsal 

 rows are present, on the ninth neither; on the dorsum of the first abdominal segment 

 at posterior edge is a buff spot just outside the lilac spot and touching it. Under side 

 deep ochre butt"; feet and legs greenish brown. Length, 40 mm. 



Gradually the larva changes, the specks disappear on the anterior and also on the last 

 segment, so that the extremities are solid green ; on the middle segments the specks 

 and marks become less distinct ; the ridge at base becomes yellow, the whole under 

 side port wine color; all the lilac spots change to bluish, the two spots on the first ab- 

 dominal segment to brown-buff. 



Finally, before suspension, the whole surface becomes dull, ochrey yellow, the red 

 of lower side Ijecoraes dull and yellowish, or dull salmon, the lilac spots on back change 

 to pale black, but the spots below the basal ridge retain their blue color, but are dull. 



Chrysalis. The ventral side highly arched, the dorsum much incurved, the former 

 narrow at summit, particularly on the thoracic segments, rounded, the sides sloping ; 

 the dorsum rounded, the sides somewhat flattened to the lateral ridge, which is promi- 

 ment, carinated, and extends from end to end ; head-case long, flattened transversely
