Rhombic Leatherbug Syromastus rhombeus

I found this in grass at the edge of a wood and near a stream. When I got home later that morning a second individual landed on the outside of the window of my first-floor study. I should have taken a photo from inside but attempted to pot it by reaching out of the window, which didn't work as it flew off again. The shape seems to be highly distinctive so I'm happy that it was the same species.
