Hercules Beetle (Scarabeus hercules = Dynastes hercules, plate 40b) from Le rgne animal (The Animal Kingdom) by Georges Cuvier. I don't see the set of scarab beetle plates in the BHL Flickr set--I found this by paging through the reference on BHL itself. I cleaned up the background, cropped, and downsampled from the original to produce this one. Usually this species is shown in a lateral view--interesting to see a dorsal portrait.
