What type of Beetle am I ? - Cotinis mutabilis

What type of Beetle am I ? - Cotinis mutabilis
San Jose, Santa Clara County, California, USA
August 27, 2005
Size: Approx 2 1/2 inches long
As I have never seen this type of insect, could you please ID it for me.

Just Saw it in Nevada - Las Vegas
I've never seen one of these before, but found a dead one near a peach tree. The iridescent green/blue colors are incredible.

Cotinis, likely C. mutabilis
This is a scarab of the genus Cotinis, called "Green June Beetles" or "Green Fig Beetles".

This checklist of The Scarabaeoidea of California by Art Evans lists just Cotinis mutabilis for that state, so that is presumably the species.

Sounds right
Evidently common in CA now. See also here.

Scarab beetle
This is a species of scarab beetle (Scarabaeidae). Species is probably Cotinis nitida

I agree
I agree, and the common name for beetles like this is June Bug. Kids in the South used to tie a string around the insect's leg and fly them like a kite!

They might just be setteling
They might just be setteling in in Northern California but, there not any recent phenomena in southern California. In San Diego CA they've always been there and were always called "June Bugs" and As far as anyone could tell; identicle to their southern state counterparts in apperance and timing.
