I have been scanning through my old images of Prosotas dubiosa, when I came across these two, which I now think may be wrongly labeled. Both these two images are from Chiang Dao, n. Thailand. These two look quite different to the usual P. duboisa, and I think they are more likely Prosotas noreia, which is a rather scarce butterfly in Thailand.
