Chrysalis...or however you spell that?

Considering the location, as mentioned by others, tension fracture is much more likely. Someone must have bent the tips backward, probably to make the side profile look better. I have done that a couple of times without thinking, with or without dry heat, not sure. If you are worried, you can put tip underlays on both tips. You can even recurve them a little in the process.

That far out on the tip you might even be able to sand out whatever they are but it would mess up the nice patina you've got going there I'd just shoot it. I think if there was going to be any chrysals on that limb they would be on the inner third.

I had the same on the back of a well in shot osage bow, I ground off the back and bamboo backed the bow to be on the safe side.

They weren't cracks in the finish as has been suggested, I found they were still there as I ground off the back, I got past them before I bamboo backed the bow.
