In case I didn't mention it earlier, all moths with green coloration will fade to gray in a collection over time. Even fresh though, the female can look all gray. The males on the other hand are all green, and look virtually identical to the Drab Prominent I pictured earlier. In the Drab, the zig-zag lines end in a black tip. On this species, those lines end in white tips.
First thing to do is split them into two groups:
Base color of the wings yellow to orange
Base color of the wings tawny or brown
