What species?

Hello everyone,
I got some species of mounted butterflies, but I don't know which species..
This is one of them. Can someone tell me which species?
And maybe also male or female.?
Thanks in advance!!

I saw the picture isn't very well..
I thought it's something like papilio Paris or bianor.

I got them from China, so that might be possible.
Thank you very much! Is it special that it is dark?

Henk
