Color of elytra
I've added some more photos of the same beetle taken at a different angle. A couple are repeats (downloaded the wrong ones). Sorry about that--I didn't know how to delete them once I'd submitted them. I've adjusted some of them to increase the brightness, saturation, and contrast. I think the color of the elytra are definitely black--that is what I remember from the live subject. I may have to wait until next June to collect live specimens. I only saw the beetles in the area for a short time in June. I did collect one that I found dead. I'll see if it's still in good condition (it's not here with me right now).

thanks, Dan -- this is definitely color, not just shade

Dendroides marginata Van Dyke ?
The lighting makes this a difficult call. This is certainly an adult female of Dendroides. If the elytra really are mostly piceous to black (as the image suggests), then it is Dendroides marginata Van Dyke. If, however, this is a shadow and the elytra are actually testaceous to rufotestaceous (as could be the case, especially if the specimen is a wee bit teneral), then it would go as Dendroides ephemeroides (Mannerheim). Both species are candidates for this region - although I seem not to find a single Del Norte county record. Specimens to study would be fantastic. Take some bodies, as well as images - these are not commonly encountered animals!
