the cell beyond, two and two, except the apical spot which is single ; twO' 

 spots beyond cell-apex ; a spot at base of interspace la and 1 followed by 

 two, short, oblique, macular bands ; a discal series of spots, decreasing in 

 size towards the costa and a postdiscal series of smaller spots that begins 

 with two in interspace 1 ; the spots in interspace 7 in both series are out 

 of the line, placed outwards. Hindwing : three series of similarly coloured 

 markings that run transversely across the wing more or less parallel to th& 

 dorsal margin, the upper markings, (these in interspace 7, that is) white ;. 

 a short, greenish stripe at the extreme base of the wing. Underside : fuli- 

 ginous brown or brownish black, more or less suffused with pink along the 

 costal margin, on apical area and along the outer margin of the discal 

 markings on the forewing, broadly along the dorsal and terminal margins 

 and at base of interspaces 6 and 7 on the hind wing ; markings similar to' 

 those on the upperside but less clearly defined and somewhat more grey 

 in tint. Hindwing black, inwardly red-margined spots superposed on the 

 pink area in interspaces 6 and 7. Cilia very narrow, pale pink. Antennie, 

 head, thorax and abdomen black ; thorax above and th'j abdomen on the 

 sides streaked with greenish grey ; beneath ochreous grey, touched on the 

 thorax with pink. Female similar, but with a streak of greenish white' 

 along the dorsal margin on both under and upper sides. — Expanse- 

 90-102mm. 



The ground-colour of the underside is somewhat variable ; this, in some 

 specimens, is much paler than in others and varies also in the amount of 

 tint of pink suffusion. Burmese specimens generally have indications of 

 a more or less complete series of red spots on the underside of the hind- 

 wing in continuation of the red spots at base of interspaces 6 and 7 : in. 

 this they approximate to the Andaman and Nicobar race. 



Larva. — Like that of P. doson. Head of the usual shape, large, green. 

 The body is the same shape as that of doso7i : is swollen about segments 4, 5, 

 decreasing perfectly regularly to the end, the sides of the body more or' 

 less perpendicular from the flattened ventrum ; the thickest part is at 

 segment 4 ; the anal segment is narrowed, more or less square at extre- 

 mity, ending in two simple, curved, divergent spines which are separated 

 at their bases by an interval equal to their own length ; segment 2 has 

 a dorsolateral simple, thin, pointed metallic blue-black spine on front 

 margin which is 1'5 mm. in length ; the two directed out in front and 

 diverging one from the other ; segment 3 has two similar, smaller, curved 

 spines, one on each side, laterally and centrally ; on segment 4 are two 

 longer, similarly situated spines of 2 mm. in length (one to each side),, 

 from an orange spot. These spines are brittle and break oft' easily from 

 the base. Surface of body smooth, dull, the segments well marked, though, 

 the margins are in no way constricted. Spiracles rather small, oval,, 

 black. Colour of body dull grass-green, obscurely blotched darker; a
