[1.12.1] Getting a ResourceLocation from entity name

I'm back in modding! Unfortunately, like usual I want to use the latest version. I'm in the process of converting my mod's code from 1.10.2 to 1.12.1.

In my old code I used the name of entities to get their colours in the EntityList.ENTITY_EGGS list. Simple example of one of the things I was doing:

EntityList.ENTITY_EGGS.get(entityName)

Now, the list seems to have been changed to be a ResourceLocation map, so to get a key in it, I assume I need the ResourceLocation of the entity. Is there a way for me to get it? I assume I can't just construct a new ResourceLocation because it would be a different instance of ResourceLocation.
