Beautiful specimens
The ones I've seen up here in Fresno, although beautiful, don't compare.

Moved
Moved from Paracotalpa.

As usual...enjoyed your lovely, clear, images
But when I first saw this post I thought...this must be P. granicollis!   I figured your usual Westwood, CA, stomping grounds are within the range of that species, rather than the similar looking subspecies rubripennis of P. ursina, which occurs way down in southern California.

Then I actually read the location info in your post :-)

So, I'd guess you're right. You can check out the key and discussion in Saylor's 1940 treatment for more affirmation here.

 
Thank you Aaron!
I did check out the key, and would agree that this specimen would be subspecies rubripennis of P. ursina. Hopefully someday I will find P. granicollis up here in this neck of the woods!

This beetle was collected sometime around 1969-1970 from within the costal sage habitat of the area. It has always been a favorite in my older collection.
