The history of the subterra- nean species is in general as follows : The beetles appear quite early in spring, and may be noticed in fields where a sod has been turned down, during the first days of May, or earlier in the Southern States. They fly quite rapidly in mid-day, copulate, and later seek a place to oviposit. During May or June, earlier or later, according to the species, the eggs are laid in grass-land or where there are plenty of weeds,—in other words, wherever vegetation, especially of a grassy character, is abundant. The larvae hatch by midsummer and feed upon roots, growing but slowly and requiring, indeed, in many cases, two or three years to complete their development. Pupation takes place in fall, and usually the change to the adult also takes place before winter sets in, though they remain quiet, and do not voluntarily emerge until the spring following. This brief sketch does not apply in its entirety to all the sub- terranean forms even, but it applies very well to the majority
