Hi Mike,
Of the Ponderous Borer, Ergates spiculatus, BugGuide notes:  “In a quick review of Google mentions this beetle has also been called a Pine Sawyer, Western Pine Sawyer, Spined Woodborer, and Ponderosa Pine Borer. The last name may be a conflation of Ponderous Borer and Pine Sawyer although it should be noted that ponderosa is Spanish for ponderous and would be a logical name for Spaniards in early California to give to both the huge pine trees of the high Sierras and the huge beetles that bored in them.
