N. biguttatus, i believe
Important guideline to follow in the future for best results: Lynette--
as a favor, could you please flip your beetle pix (this one and others) so that the specimen faces 'north'? standard orientation makes image recognition a lot easier. Thanks!
Moved from Notiophilus.

and I'll try to remember that.

Nice photo of Notiophilus.
However, most species of this genus are not easily separated on the basis of field photographs. Furthermore, I don't believe there has been published a single comprehensive taxonomic key that covers all the western members.

Is there a list of western species?

Nine Notiophilus species known in the Northwest:
N. aquaticus, biguttatus, borealis, directus*, intermedius, nitens*, semistriatus, simulator*, sylvaticus*. Four asterisked (*) names are given WA status in the 1993 catalogue by Bousquet & Larochelle. The others are known in political regions adjacent to WA and therefore are additional candidates. As it turns out, these nine species are covered in a reliable key by Lindroth (1961). Lynette, I am familiar with that key and so you cam mail me the specimen for determination/retention if you like.

I can't mail you this one, since there is no hope of ever finding it again. But, I can catch one and mail it to you. I suppose I'll have to kill it first... alcohol. I'm assuming that the large population we have of these is all the same species?

Oh I see you have good instructions for mailing on your account page. Very nice.
