streaks fuliginous-grey. Hindwing intense black or blue-black ; the outer vein borders 
paler; basal patch scarlet; white apex of the cell, cliscal patches, anal spot and 
marginal lunules, as on the upperside, the red borders somewhat paler, and the 
upper lunules and their cilise being white or greyish-white, or these lunules are 
slightly red speckled. Abdomen with broad yellow-ochreous lateral bands. 
Expanse, ? 5J to 6 inches. 
Specimens of this form of female from the Khasia and Jaintia Hills: Shilloncr, 
Assam ; Nepal; and Kyaikto, Tenasserim, the latter, taken in February, are in the 
British Museum. We have it from Nepal, taken by Gen. G. Ramsay; Rangoon 
and Tounghoo, Burma. The lower figure on Plate 15 of Clerck’s leones, evidently 
represents this form, with the tails broken off. 
Distribution. —This is “ a very common species in Sikkim, and is found from 
April to December, from the Terai up to 5000 feet. The female is polymorphic, 
but three distinct forms may be defined, though each is more or less variable. The 
first form is tailless, and is more like the male; the second is also tailless, but has a 
large white patch on the hindwing; the third is tailed, and is marked with white 
spots on the disc of the hindwing. The second form of female is alone rare, the 
third form is the commonest of the three forms” (cle Niceville, Sikkim Gazetteer, 
1894, 172). Mr. H. J. Elwes also records it as being “ common in the lower valleys 
of Sikkim, and is found as high as 4000 to 5000 feet, from April until December. 
The common form of female is tailed, with a considerable amount of white in and 
beyond the cell of the hindwing ; but tailless females are also found, without any 
white markings, and others with a broad white patch on the hinder margin of the 
forewing ” (Tr. Ent. Soc. Bond. 1888, 428). Col. C. Swinhoe records it as 
“ apparently very common in the Khasia Hills, in all its varieties ” (Tr. Ent. Soc. 
Lond. 1898, 312). Mr. J. Wood-Mason obtained “forty-two males, six females 
(figured by Distant as female of Mestor , Hiibn.), one female ( Agenor , Cram.), eight 
females ( Alcanor and Achates, Cram.), in the forests and gardens in and around 
Silcuri, Irangmara, the Doarband Pass, Hasooria, and Rupacherra, in Cachar, where 
it was almost always to be seen from April 3rd to August 10th. On one occasion 
all four forms were seen on the wing together in a group, having evidently just 
emerged from the chrysalis state, and a specimen of each was taken. All the forms 
of this species are inodorous ” (Journ. As. Soc. Bengal, 1886, 373). Capt. E. Y. 
Watson, during the Chin-Lushai Expedition of 1889-90, took “one male (form Gilix) 
at Tilin, in March, one male and two females (form Mestor ) at Tilin, in November 
and March” (Journ. Bombay N. H. S. 1891, 53). Col. C. H. E. Adamson records 
“the forms of female Agenor and Achates as being common throughout Burma. 
The form Mestor having been taken only in theBhamo District. The male is a very 
rapid flyer, while the females are heavy, sluggish flyers and easily captured ” (List,
