Seems to be bee wolf time, and this looks like another Philanthus. I count 11 flagellomeres, so it should be a male. A few days ago I saw this species farther downstream in this dry wash.
Using the key to the California Philanthinae by Bohart & Grissell (Bull. of the Calif. Insect Survey, vol.19: PDF
), I arrived at P. multimaculatus. Doug Yanega (Dept.of Entomology, Entomology Research Museum, UC Riverside, Riverside, CA) confirmed the ID.
