This is the commonest species of the genus, and by superficial characters other than those in the key, the moderately projecting tylus and proportionally narrower form separate it from lutarium as already noted, and its larger size from testaceum. This species has the same general habits as the others, but its life history is known in detail. The adults hibernate buried in the.
