This is either #4873 Glaphyria fulminalis or #4874 G. cappsi. Despite what the MPG maps show, both species were collected by Gillaspy at Brackenridge Field Labs in Travis Co., TX, with the latter species quite a bit more numerous than the former. I'm uploading three rather unsatisfactory images. This moth was difficult to get an image of without a lot of reflected glare, perhaps indicating a worn specimen (?).
