This is a well-defined species of the 7. lutala group. 
Tanaecia Doherty?, sp. n. 
Allied to 7. aruna; the male more like 7. valmikis in 
form, the costal margin being less arched than in 7. aruna; 
the centres of the black basal markings pearly greyish; the 
black hastate markings more compressed and followed by 
larger diffused submarginal spots than in TJ. aruna; the 
costal area and the area beyond the cell of secondaries 
pale and slightly vinous in the male; the discal belt more 
white-varied than in 7’. aruna, the hastate markings very 
small and followed by more elongate, larger, diffused spots: 
under surface nearly as in JT. valmikis, but paler and more 
pearly, with smaller black markings. The female below 
is especially pale, with a greenish wash over the basal area 
and the whole external area bluish opaline.

I must confess that I cannot discover a character by which 
to separate the males of NV. kesava and NV. rangoonensis ; 
there are differences as regards the definition of the markings 
of the under surface in individuals assigned to both forms, 
and these I should be inclined to attribute to seasonal in- 
fluence. In like manner, I believe, when these insects are 
carefully bred it will be discovered that females of the ran- 
goonensis type represent the wet phase and those of the 
kesava type the dry phase of the same species. NV. rangoon- 
ensis is not confined to Burma nor J. kesava to India; we 
have both from Silhet, Assam, and Tenasserim.
