Long Horned flower beetle, almost? - Diabrotica undecimpunctata

Long Horned flower beetle, almost? - Diabrotica undecimpunctata
Big Basin HQ area, Santa Cruz County, California, USA
November 28, 2010
Size: 1" ?
I looked at a lot of Long Horned Flower beetles, and the had a sort of hunched shoulder look compared to the rounded shoulder loo of this one, and they have sort of triangular bodies compared to a more rounded one, and they also had flat shell backs, where this one is also more rounded.
Also I never found a photo of any beetle with a yellow mantle, is this something that loses it's color as the weather dries up?
Found on a mossy redwood post in cold (45-50 deg) temps when the sun was out for an hour.
