Its body is long, narrow, and flattened, of a light bay-brown color, with the head and an- tennae darker. The thorax is very short, and armed on each side with three sharp teeth; the wing-covers are nearly of equal breadth throughout, and have three slightly ele- vated ribs on each of them. This beetle measures from one inch and one quarter to one inch and a half in length, and about three or four tenths of an inch in breadth. It flies by night, and frequently enters houses in the evening, from the middle of July to September. The second family of the Capricorn-beetles may be allowed to retain the scientific name, CERAMBYcnXE, of the tribe to which it belongs. The Cerambycians have not the very prominent jaws of the Prionians; their eyes are always kidney-shaped or notched for the reception of the first joint of the antennae, which are not saw-toothed, but generally * P. cylmdricm of Fabricius.
