edge, and tliere is also a broader discal area between it and the siibraarginal spots ; 

 tlie red anal-lobe spot is smaller and narrower, and is separated from the blue-scaled 

 lunule above it by a black semicircle. Underside. Ground-colour much darker 

 than in P. asiatica, the veins and markings bx'oader black lined. 



Expanse, 3 to 3^ inches. 



Habitat. — Eastern Himalayas; E. Tibet; W. China. Chin Lushai and N. Chin 

 Hills, Bui'ma ; Shan States, Burma. 



Distribution. — Mr. H. J. Elwes writes that " neither Moller nor myself have 

 ever seen this species in British Sikkim, and I believe it only occurs in the higher, 

 dry hills of the interior, probably from 8 to 10 or 12,000 feet elevation, whence our 

 native collectors have brought very numerous specimens in July and August" 

 (Tr. Ent. Soc. Lond. 1888, 437). 



Dr. Hooker (Himalayan Journ. ii. p. 26) records P. MacJiaon as being " found at 

 Ohoongtam, in Sikkim, and on p. (>5, that the larva of the Swallow-tail butterfly 

 (P. Machaon) was common in the Lacheng Valley, feeding on Umbelliferous plants." 

 In the late W. S, Atkinson's collection were specimens labelled " Lacheng Valley." 

 In the British Museum are specimens labelled " Chumbi, Bhotan," from Mr. G. C. 

 Dudgeon, and " Yatung, Tibet, June," taken by Capt. F. C. Colomb. In Mr. J. H. 

 Leech's Cabinet ai"e specimens taken at Moupin and Wa-ssu-kow, W. China. Mr. L. 

 de Niceville records it from the " Chin Lushai Hills, Burma " (J. Bombay N. H. S. 

 1890, 387), and Capt. E. Y. Watson from the " North Chin Hills, Burma," at and 

 above 6,000 feet elevation, in March and April" (id. I.e. 1897, 671). A male from 

 Kokang, N. Shan States, and a female from the S. Shan States, are in Mr. W". 

 Rothschild's collection ; a male, also from the N. Shan States, is in the British 

 Museum. These three Shan States specimens are smaller than typical Sikldmensis, 

 each, on the hindwing, having the blue-scaled lunule separated from the red anal 

 spot, but they have the abdominal margin very narrowly black bordered, with the 

 yellow extending up the submedian interspace to its base.
