and shifted outwards, the eighth elongate sloping upwards to 
inner margin. A spot at base of median nervure; another 
just beyond the cell; a large quadrate dark brown spot below 
Ist median nervule followed by another nearer the base on the 
inner margin; a large dark spot on anal lobe, a rough dark 
line on each side; a large dark spot (exterior to. post-discal 
row) between Ist and 2nd median nervules; ochreous brown 
spots along hind-margin above 3rd median nervule to apex. 
Black anteciliary line. Abdomen below ochreous; above dark 
fuscous. |

Mr. Druce kindly examined this specimen for me and re- 
ported it as “probably new and when perfect has long tails 
and comes into the Manto Group of genera—most likely new 
genus. Your specimen seems to be a ¢” (in litt. March, 
Lily, + 
The specimen before me has no secondary sexual characters.

Only recorded from Borneo. 
Closely allied to J. anasuja, Felder (from Malay Peninsula 
and Sumatra), and to the next species (J. metasuja, H. H. 
Druce) ; and from an examination of the figures and descrip- 
tions of these three species, one might suggest that they are but 
local races of one species. Thus anasuja occurs in the Malay 
Peninsula and Sumatra; jusana and metasuja in Borneo, the 
former from Sandakan to Sarawak and the latter on Mt. Kina 
Balu only. A male in the Sarawak Museum has a thin blue 
apical band intermediate in width between these last two 
species. 
Injuries. (1) ¢, both tails cut off and neat circular bite 
removing the large anal spot on left hind-wing. (ii) @, large 
bite diagonally across the left hind-wing removing more than 
half the wing.

1. A fine male has just been captured (October 1911) on Mt. Klingkang, 
Sarawak; it has two short tails, (like the female Thamala miniata, Moore, figured 
by de Nicéville in Butterflies of India, Vol. IIL, pl. XXVIII, fig. 213), the outer 
of which from the 1st median nervule is 6 mm. long, the inner from sub-median 
nervure is5mm. This feature together with certain peculiarities of the neu- 
ration will iu all probability necessitate the founding of a new genus as Mr. 
Druce suggests ; this point I hope to settle in the near future.
