I considered Heliocosma argyroleuca, due to general apparance. Yes this specimen is a little worn. but the pattern on it does nor match Heliocosma argyroleuca. Look at the way it is sitting. 'head up, wings down', antennae over its 'back' . No sign at all here of any erect scales on the forwing that are present in Heliocosma. I've looked at all the images here of Live Heliocosma argyroleuca, and also quite a few on ALA and none are holding the antennae like this specimen is. They are either shown held forward or down tucked into leading edge of forwing.
