NOTE DD. THE DORR, OR CLOCK-BEETLE, (_geotrupes stercorarius_) p. 217. This insect, familiar to us Americans from our reading, is not found in our own country. It much resembles, however, our common rolling beetles in its appearance, and these are closely allied to the far-famed sacred Scarabæus of the old Egyptians. The clock, or dorr, “is broad, short, and clumsy”—“black in the upper parts, but with wing-cases tipped with violet, while the legs and under surface are steely blue, glossed with green and purple.” “To look at the unsullied polish of his mail, one might suppose him risen, like the green gold-chafer, from a bed of roses; whereas, being a true Scarabæus in nature, if not in name, there is little doubt, when we see him in his waving flight, of his having left recently a bed of a very opposite description—a bed in short of dung—wherein through the live-long day he has been reposing, or whereat, like his Egyptian prototype, he has been hard at work, helping, perhaps, his partner to roll masses for the enclosure of her eggs, or to bore holes for their reception.”—_Acheta Domestica._ The dorr is one of those creatures which seek safety in feigning death; when touched, it immediately drops to the earth, stiff and apparently lifeless, suffering itself to be handled without the least sign of animation; but when left to itself, it will in a moment resume its faculties, and take flight again. It is possible that some American reader, familiar with the epithet “shard-borne beetle,” may not be aware that the word _shard_ signifies a fragment of pottery, this insect being often found among rubbish of that kind, or about loose stones. Such is the dorr, which, in the summer evenings of England, “wheels his droning flight.” NOTE EE. THE DEATH’S-HEAD MOTH, (_acherontia atropos_) p. 222.
