This is a difficult one because it looks like it is the female of Pelopidas thrax.
The ssp masta is recorded from Sikkim to Manipur ,& as it feeds on cultivated grains could easily occur in West Bengal.
Pelopidas thrax: Male with the brand paler & more prominent.
Ground colour more uniform ; HW spot 6 large ,often largest & rounded (esp. male) ;cellspot also typically large.
HW spot 4 & 5 often more prominent ( esp. in female tend to be wide (ie elongate) .
HW spot 7 always absent.
"Face & chest" whiter than in mathias or agna.
Israel male Greece female.

The large rounded HW spot 6 & general appearance suggest the female P. thrax but it is hard to be sure.
Note the HW spots are edged with dark brown. If you look carefully spots 4 & 5 appeared elongate. If this is correct the ID is almost certain.
P. thrax ,Greece right side female.
