Mating Milkweed Longhorns

Dear LALehner,
These are indeed mating Milkweed Longhorns in the genus
Tetraopes, most likely the Red Milkweed Beetle, Tetraopes tetrophthalmus.  According to BugGuide, they can be identified through a:  “combination of broad, disk-shaped hump (callus) on pronotum, strong elytral spots, especially the broad subhumeral spot, and unringed antennae are distinctive for this species.”
