Species: Nysius sp.
Common name: Seed bugs.

All members of Family Lygaeidae (Seed Bugs) are small (most less than 10 mm long), have four-segmented antennae, ocelli (A small simple eye) and wing membranes with four or five parallel veins.
This is another bug rather than a beetle. Beetles have their forewings hardened into shells (elytra) that completely cover their rear wings. Bugs have the triangular or X marking you see above with the exposed wings at the back.
The genus Nysius contains approximately 106 species throughout the world. Like other seed bugs, there are some species of Nysius that are crop pests of wheat and other grains, and vegetables.

Nysius is a difficult genus and many are very difficult to identify without reference to a specimen.
