I looked at many photos of this species, as well as additional ones in my series. There is some variability, but I believe this ID is correct. Note that the contrasty gray and black pattern depended on the angle of the light. All these are the same individual, even though the thorax in particular appears nearly all black at some angles.

Amazing what a difference light makes.
Nice series! It's interesting to find that some black thing aren't. I started using the camera's built-in flash on all-black wasps and bumble bees and impressed myself with the results. Yet another effect has been mentioned by Eric, who has pointed out that angle of light has a large effect on an insect's metallic surfaces.
