of the cell ; these are followed by a black bar between that of the basal bands and 

 the large anal spot ; beyond is a submarginal row of black slender broken lunules, 

 which are more defined than on upperside, and then the marginal zigzag row of 

 lunules ; basal interspaces tinted with dark olivescent-yellow, and the outer discal 

 interspaces clouded with bright yellowish-ochreous. Bodij and legs greyish-white ; 

 sides of abdomen pale ochreous, with a longitudinal row of black spots ; thorax 

 above clothed laterally with fine grey hairs, a longitudinal black dorsal streak 

 extending to front of head ; collar and sides of frontal tuft ochreous ; forelegs 

 blackish above ; tarsi blackish ; antennas black. 



Female. Upperside similar to the male. Hindiving with the dark grey caudal 

 patch broader. Underside similar to the male. 



Expanse, c? 3 to 8f , ? 3f to 4 inches. 



Larva. — Smooth ; slightly distended about the fourth and fifth segment ; with 

 two short pointed subdorsal tubercles on third and fourth segment, two fleshy 

 tubercles on second segment, and two on anal segment. The colour, according to 

 specimens reared by Davidson and Aitken (I.e. 1890, 579), " in its early stages, is 

 pure white, marked only with thin transverse lines of black or dark green ; at the 

 last moult but one it becomes yellow, with thicker lines, and after the last moult 

 attains the colour shown in our figure. Feeds on Unona Laivii, N. 0. Anonacese." 



Pupa. — Attenuated at anal end ; thorax truncate in front and with a short 

 frontal-pointed dorsal prominence ; colour pale green, with lateral pale yellowish 

 line. 



Habitat. — Ceylon; S. and C. India; Assam; Sikkim; Bhotan ; Burma; Shan 

 States; Siam ; Tenasserim ; Malay Peninsula ; Sumatra; Java; Borneo. 



Distribution and Habits. — In Ceylon, according to the observations of Mr. 

 F. M. Mackwood, this is " a scarce butterfly, being found only in a few localities, 

 widely apart, at about 1,500 to 3,000 feet range. Capt. Hutchison obtained it in 

 the Eastern Province, in plains and forest, in August. Capt. "Wade took it in the 

 Kottowar forest, and at Galle ; rare elsewhere" (Lep. Ceylon, i. 142). Dr. N. 

 Manders says it is " rare and local in Ceylon. It seems to be more partial to the 

 Eastern and drier pai'ts of the Island " (J. As. Soc. Beng. 1899, 223). 



In S. India, Messrs. Davidson and Aitken write, " Our acquaintance with this 

 species is limited. We first met with it at Grairsoppa, in the South of Kanara, but 

 have since found it at one or two places further North. It begins to appear in 

 March, and there can be little doubt that it is on the wing for a few months only, 

 like P. Nomius. On April 26bh, 1893, a female deposited a single egg, and though 

 the little caterpillar which emerged perished by starvation, the plant {Unona Lawii) 

 not being then obtainable, we next year succeeded in getting a few more, and an 

 amateur figure was made of the larva and pupa. The pupa is supported by an
