The male beetle on top is Cicindela punctulata, while the female is Cicindela repanda. It seems there was a case of mistaken identity. The female beetles have a depression in the side of the thorax called the coupling sulcus which is shaped to match the mandibles of the males. Usually, this makes it easier for the females to dislodge males that are the wrong species. Looks like the overzealous punctulata caused some damage to her thorax.
