During my collecting trip in June to Belize I caught two of these beetles. They were on fruit trees more specifically lime trees. Can anyone ID them for me?

I do not believe that this is a Chrysina. That genus belongs to the subfamily Rutelinae.
This looks more like something from the subfamily Melolonthinae. A very diverse subfamily of scarabs of which fruit chafers are members.
There are a fair number of species within the subfamily that look like dirty Chrysina species.
This is about as much help as I can offer at this point but, I think our forum member Bandrow will be able to help you further.

Greetings,
Based on the hind tarsi, I would say this is definitely a member of the Rutelinae, as is the genus Chrysina. This may be a species of Pelidnota - while we only have a couple of species in the U.S., there are numerous species in Central America. The C.A. Pelidnota vary in coloration from a rather dullish orange, as in our P. punctata, to species with highly iridescent elytra.
Question - some droplets of moisture are clearly visible, but is the surface of this specimen deeply pitted, or is that just a effect of the liquid?
Cheers!
Bandrow

Atfirst I thought it was pitting when I took the photo. Checking in on it today and no pitting is visable. I put it into an envelope and froze it. Here is the data I have:
GPS: 17.098067, -88.975360
6/3/2021 2:30pm
86F 70% Humidity
I caught a total of 2 on the same lime tree.
Green Hills Butterfly Ranch was surprised that I wanted beetles and will collect for me in the future. Their bait traps collect large numbers of large black weevils and flower beetles.
Thank you for the insight Bandrow!

This one appears to have an orange undertone. When brought close to LED light it becomes gold. When directly near the light, a metallic green undertone appears and the head becomes all metallic green.

 Here is a photo just now which also shows the green. I cannot get the gold to show on my camera. |

Greetings,
That looks a lot like a species of Pelidnota, now that the moisture is removed and the surface can be clearly seen. Can't give you more than a genus, but hopefully this much helps...
Cheers!
