extremities, and prominently edged with white on either side. Six indistinct oblique 

 stripes of paler green than the ground-colour, but darker above, adorn the sides. 

 That which formerly marked segment 4 no longer appears, but the seventh, which starts 

 below the spiracle on segment 10 and leads up to the base of the horn, is now an 

 elongated broad band of cream-white and exceptionally prominent. The spiracles 

 are orange and brown, the pair on segment 2 being lighter in colour. Legs pink and 

 white. Claspers adorned with a mauve patch and brown fringe. Anal flap and 

 claspers bright apple-green and covered with tiny brown tubercles. 



Pupa. — Bright warm mahogany-brown and glossy. The back darker, with many 

 small projections both on thorax and abdominal segments, making it extremely rough 

 to the touch. Free proboscis-sheath large, much curved, and heavily ridged with 

 transverse bars. Anal spike or cremaster very stout and pointed. 



37 d. Peotoparce sexta paphus. (Plates VII. li-k; XV. d.) 

 R. & J. p. 69. 



General Bistrihution. — Costa Rica to Argentina. 



Common on the seaboard and lower Andes both in the larval and imaginal con- 

 ditions. Not obtained from the Interior. Moth often taken at light. 



Though allied to the next species, the adult larva differs from it in certain very 

 essential particulars, notably the absence of yellow stripes on its head and the character 

 of the caudal horn, not to mention the black dots above the seven oblique stripes. 



In regard to its " snapping " propensity, its " sweating " prior to pupation 

 (cf. P. rustica), the comparatively small size of its frass, and its great susceptibility 

 to the attack of dipterous parasites, it is like F. mussi. 



Puparium, a large subterranean cavitj'. 



Ova.— Singly on leaves of potato, tomato, nicotiana, etc. 



Lakva. — First and second instars (unfigured). Probably very similar to F. mossi. 



Third instar (fig. h). Ground-colour plain blue-green, with seven oblique white 

 stripes leading in direction of caudal horn, which is now fairly long, only slightly 

 curved, darker in colour, and inclining to yellow. Oblique stripes darker above, with 

 traces of pure blue on the edges. Legs, spiracles, and border of anal tlap raw sienna. 

 Head plain, but warmer green. 



Fourth instar (fig. j). Ground-colour blue-emerald or full clear green. Skin 

 velvety and smooth. Head large and round, plain blue-green without markings. 

 Legs cream-white with black rings. Ventral area and claspers dull green. Anal flap 

 clearly edged with yellow. Spiracles maroon with dark centres. Caudal horn com- 

 pletely changed in form and colour — now very short, thin, smooth, sharply curved 

 and pointed, and in colour pink, inclining to maroon at the tip. Oblique stripes 

 cream-white in the region of the spiracles, edged above with viridian and blue, and an
