I took a picture of this beetle about 25 miles south of Pueblo, CO on a bit of sage. I have searched the internet and have not found any satisfactory match. Can you help?

This is definitely a Scarab Beetle, and we believe it is a May Beetle in the subfamily Meloionthinae. This image of Dinacoma caseyi from BugGuide looks very similar, but it is only reported from California and according to BugGuide: “Only known population occurs within the Palm Canyon Wash area in the southern part of the City of Palm Springs, Riverside County, California. The species is believed to occupy less than 800 acres of land. – FWS.” Perhaps this is a close relative in the same genus or perhaps a related genus. We will try to contact Artur V. Evans and Eric Eaton for assistance.
Eric Eaton responds.
Pretty sure this is Phyllophaga lanceolata, a type of May beetle that is pretty common in Colorado. Looking forward to Art’s assessment.
