Saw this guy at the Rockhound State Park near Deming, NM in late November 2006. It is a desert area, and there were lots of the familiar Darkling beetles with their raised hindquarters in the vicinity. We have those at home (in So Cal) and I am very familiar with them. This particular beetle however I have never seen before. The photo shows it at about 160% size. Thank you,
This is a Blister Beetle in the genus Megetra.
