Gehyra marginata? I've had them hatch anywhere from 120 days, all the way to over 200. As a matter of fact, I'd decided one clutch wasn't hatching, had set it aside to pitch into the composter in spring (this was in the dead of winter). Luckily the delicup stayed in the herp room where it was reasonably warm... the eggs must have kept developing because they eventually hatched around 220 days. The hatchlings were the biggest of any marginata hatchlings I had over the years, and there wasn't a speck of yolk left in the egg, they used it all up.
If the eggs look good, I'd say keep them. If they are infertile or dead, you can still see what's inside in a year, at least you know they're good and dead.
