Well I'm not familiar with that particualr species, but I do breed collared lizards and have other desert lizards as well.
Your eggs in the pic, are looking like they are deflating, caving in, They need to be in dampened vermiculite or perlite, a few inches of it in a plastic container such as a deli cup.
And incubated at about 84 degrees, probably would take about 40- 60 days/ somewhere inbetween.
I do not know how long you have had them on dry substrate, they look pretty dented in. But theres always a chance they can come back when placed in dampened vermiculite/or perlite and incubated. Sure won't hurt to try!
If they reamain real spongey or squishy , like a water ballon feel, then they are not good.
Good luck with them.
