Oops...

I thought they looked a little "Cicindelish"

Not so sure this is O. dejeani. Not big enough, pronotum not "wrinkled" enough, and elytra don't look to be deeply pitted.

well its certainly not O. californicus, so that narrows it down to either O.audouini or O. dejeani. how common is O.audouini?

The book is not specific, other than saying these are little known beetles.

well I have personally collected O.californicus and its very smooth, and doesn't have a broad or angular thorax.and I have a few in alcohol vials in hand as well.

There is another species of Omus on the Lower Mainland: Here is a brief account:
Audouin’s Night-stalking Tiger Beetle, Omus audouini Reiche
(Plate 2) [Map 9]
Description and similar species: Length 14— 18 mm; dull black. Audouin’s
Night-stalking Tiger Beetle is variable in size but distinguished from other
Omus species by domed elytra and by the forward corners of the thorax curved
distinctly downward (see fig. 4.5B). Under a microscope, the small pits on the
surface of the elytra are arranged in an irregular pattern, with relatively wide
pitted areas divided by narrower smooth areas.

The corners of the thorax might reach to below the eyes, so perhaps this is O. audouini
Next time I see one I will catch it.
