Herbert the fish fly
An often-submitted member of the insect order Megaloptera, formerly Neuroptera.

Megaloptera needed?
I've wondered about this for a while. Does anybody want to split out the Megaloptera from the Neuroptera? I'll put a note in the taxonomy forum as well.

In terms of this California fishfly/dobsonfly, I believe Arnett (1) has a key to the genera based on wing venation, and somebody who understands that (not me) might be able to key this specimen to genus.

Not me too
I didn't even see your first comment till I had already posted mine, Patrick. I wasn't trying to dispute you. I was just too dull-witted to scroll down to the bottom of the page :-)

Dobsonfly family, perhaps Protochauliodes
It is in the Dobsonfly family, Corydalidae, of the net-winged insects, Neuroptera. It is likely either genus Protochauliodes or Neohermes, which are the two genera in that family mentioned by Powell and Hogue in California Insects (1). Male Neohermes have bead-like antennae (and females too, in the species we have in North Carolina). Protochauliodes is said to have thread-like antennae. In your Flikr photos, I can see that the antennae are slightly serrate (saw-like), perhaps. So I'm not sure. If I had to make a bet, I'd guess Protochauliodes, but I'm not familiar with western neuroptera at all.
