Separation of Lethe sinorix and Lethe kansa

[DaveChiangMai]

I have been checking my Lethe images. These two attached images are from Mae Wong (w Thailand), and I am having a very hard time deciding whether they are L. sinorix ot L. kansa. Some individuals of these two species seem very difficult to separate. Comments please. I tentatively have these down as L. sinorix, but being to think they might both be L. kansa.
With thanks.

Many thanks. Very useful pointer - not in the literature!
