Chrysomelid? - Peltis fraterna

Chrysomelid? - Peltis fraterna
Grassy Lake, Teton County, Wyoming, USA
August 18, 1998
Size: 7 mm length
General appearance and tarsal formula (apparently 4-4-4) make me think Chrysomelidae on this one, but I'm just getting started keying it out. Any guesses on family?
