Insect and Spider Identification: CLOSED: ID Please: beetle with half circle head, Net-Winged Beetle?, 1 by Dirus

I guess what I've been calling a head is more like a neck? What's that part called anyway? Not a thorax? Maybe pronotum or mesostemum? Is there a common word for it?

Anyway this one has a half circle there. This one was found on my Cucumis melo 'Golden Sweet' vine, which, for some reason, gets very few insects on it.

I was trying to figure it out myself but I'm stuck about this far:
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Coleoptera
Suborder: Polyphaga
Infraorder: Elateriformia
Superfamily: Elateroidea
AND maybe:
Family: Lycidae (Net-Winged Beetle)

Can someone help me figure out what species? Of course any of the above could be wrong.

It almost looks like a Plateros (http://bugguide.net/node/view/25895) but it's head is much more red and I'm in south western US, very far from the north eastern area it's usually found in.
