the orange coloration at the anal angle of hindwing as on upperside, but rather broader. 

 Expanse, ? 2*25 inches." 



Habitat. — Burma, Sikkim, Assam. 



DiSTRiBUTiox. — The type male from Tavoy in Burma is in the Indian Museum, 

 Calcutta ; de Niceville also records it from the Khasia Hills ; our description and figures 

 are from a perfect male specimen from the Khasia Hills in our collection. Elwes and 

 de Niceville's figure is misleading, the artist has made the upperside of the palpi 

 orange, it should be coucolorous with the wings as stated by them in their description. 

 We agree with de Niceville * that rudolphei is distinct from h^eln ; it lacks the 

 beautiful blue-green gloss between the veins on the upperside, and there is much less 

 orange-ochreous at the anal ansfle of the hindwings.

Imago. — Male. Upperside rich vinous-brown, much as in P. rudolphei, no 

 markings. Cilia of both wings as in P. rudolphei, but the orange portion of it broad- 

 ening more considerably at the anal angle, giving the appearance of a large orange anal 

 lobe. Underside very different to that of rudolphei, the colour being almost entirely dark 

 brownLsh-greeu, instead of being brown with the veins striated with green, as in that 

 species, all but the hinder marginal portion of the forewing and the entire surface of 

 the hindwing being sufiused with green, the hinder marginal portion of the forewino- is 

 paler than it is in rudolphei and is orange-tinted, the cilia of the hindwing is orange- 

 grey, and there is a conspicuous dull orange patch at the anal angle. Antennse black, 

 grey beneath ; palpi, head and body above concolorous with the wings ; below, the 

 paljji, pectus and abdomen dull orange, thorax orange-grey, abdomen with some orange- 

 grey lateral bands. 



Female like the male, slightly paler and duller in colour on both sides. 



Expanse of wings, $ $ 2^ inches. 



Habitat. — Burma, Malay Peninsula and Archipelago. 



Distribution. — ^The type came from Malacca, the type of pavona from .Java ; 

 recorded by de Niceville from Toungoo, by Elwes from E. Pegu, Labuan, Perak, 

 Buitenzorg ; we have both sexes also from Nias.
