My first thought was that your second picture looked jolly like the
onopordi I found this summer. I looked in Tolman and he didn't have

armoricanus is a possibility.
Here are two different individuals of
onopordi for comparison:
I'm certain you don't have underside pictures, or you would have posted them... I netted one of the above
onopordi and took this photo of the underside, which was even more conclusive in real life:
I certainly wouldn't like to call your insects without seeing the undersides!
