Green river insect, Coleoptera or Trichoptera?

I was looking through some GRF insects that I had, and wondered if anyone had an ID for this one? I am mostly familiar with insects from amber inclusions, so it is a bit different looking at them on rock. Some options I thought of were a species of beetle, caddisfly, or maybe a cicada? Any information would be great!

I would say a cicada, they look very similar with the lower cretaceous ones that come out Liaoning.

Thanks guys! What work is that from? I will try to find the description for Lithopsis and see if it is a match. Appreciate the help!

That is frustrating, an image attachment and possible species, but no citation or link.

Thank you! I will label it tentatively as a Lithopsis, until I can find some more information to confirm it. I appreciate the help!
