The history of the subterra-nean species is in general as follows : The beetles appear quiteearly in spring, and may be noticed in fields where a sod hasbeen turned down, during the first days of May, or earlier in theSouthern States. They fly quite rapidly in mid-day, copulate,and later seek a place to oviposit.
