Were you storing cut eucalyptus firewood in your garage? This is a Eucalyptus Borer. There are two similar species in the genus Phoracantha (see BugGuide) that were accidentally introduced to Southern California from Australia and they have both become well established since their native food, the Eucalyptus trees, were extensively cultivated in California. We believe your specimen is Phoracantha semipunctata.
