Apologies, I'm rotating them all to face the same way. Sorry about that. I'll leave the ventrals as they are for now, unless it would be better to rotate them as well.

Hydrophilus, unmistakable
make sure to post dorsal pics for ID in a uniform way (some of your beetles face left; others, right); head-to-12 o'clock is by far the best way to orientate pix for comparison
