Wow, doing some research
I have found bugs with the exact shape but nothing simular to the pattern. Seen at the Aiken Canyon Preserve near Colorado Springs. Ever seen one of these? I thought it was a carrion beetle just because the shell looks like it is decaying. Platyphora haroldi. Could it be some sort of flat footed beetle?
This little gem is a Pleasing Fungus Beetle, Gibbifer californicus. According to BugGuide, it is found in “Southwestern United States: Kansas, Wyoming, Colorado, New Mexico, Arizona, south into Mexico.” Additionally: “Adults feed on nectar, pollen, and some fungi. Larvae feed on fungi that are attacking wood.”
