Ischnopterapion virens

Ischnopterapion virens. The eyes are more bulging than in loti/modestum, and there is a green sheen on the pronotum and head (black in loti/modestum). The colour of virens - usually obviously metallic wing-cases, but only faintly metallic pronotum - is distinctive once you get to know it.
