Could be femorata indeed

Hello Reinoud
Thank you for your answer
What's the difference between C. femorata and C. marginata : are females distinguishable ?
I added a photo of the the face (with white hairs).

The two species are very close. Females are even a bit more dififficult. C. marginata has a more yellow shiny face instead of white one and the first antennal segment is a bit shorter. I think this is indeed C. femorata.
