This is one of the three green species of Cryptocephalus. C. sericeus, C. aureolus or C. hypochaeridis. I guess it is to small for C. hypochaeridis. The other two species I normally can devide by taking a look at the habitus, but the one in your picture seems to be twisted by the camera angle, so I can't tell by these photos.

here we just have C. hypochaeridis and C. aureolus, so the choice is just between two sp. I always find these difficult.

In this case, if you really don't have any Cryptocephalus sericeus, my guess is C. aureolus. But this is a guess, because it seems to be that this one does not look like C. hypochaeridis. It's just a feeling and I can't tell why. Maybe you can remember the size!?
