O. scabra
The textured elytra tells me this is the other NE sp. - O. scabra, but is that color real?? This looks green and they are NEVER green, always brown/black. Was this freshly emerged? Odd.

 
Yes, I think you’re right a
Yes, I think you’re right about this being O. scabra. Thank you. Even for O. Scabra, this individual is on the small side – only 18.5 mm – and the textured elytra and coarsely and deeply punctured pronotum are strong indications. I have another much larger grub that has yet to pupate. Maybe it will be O. emericola.

Dillon & Dillon do say this species has a “green or bronzy sheen." This beetle has a strong greenish hue in all my photos. I’ll post another shot in which it appears slightly more bronze. In my experience, scarabs having a “mechanical" coloration (due to a clear layer of a thickness that transmits only certain wavelengths) can appear to be different colors depending on the lighting.
