Another species very common in Europe, but its thot·ax is armed on each side with a pointed tubercle. It is an inch long, of an obscure black, with short antennre and granulated elytt·a. This Insect, with some others, evidently leads to the apterous species, all peculiar to Europe and those parts of Asia which border on it, and of which the larvre probably feed on the roots of plants. These species form the genus DoRCADION of Dalmau, which is adopted by most entomologists. The antennre are generally shorter than the body, and are composed of obconical joints, which give them a nodulous appearance; their abdomen is a sort of oval, or almost triangular. l\1. i\'Iegerle has formed the genus PARME.'A, with certain small species that appear to me to be removed from the others only by the antennre, which are longer than the body, and as theit· joints are more elongated, th~y become rather cylindri· cal than conical. According to this, we would be obliged to connect others with them, much larger, but presenting the same characters, such as the tristia, lugubris, and funesta. Among those with short an tenore, or the Dorcadions properly so called, there is one very common in Europe, but almost ex· elusively confined to calcareous localities, or to such as border on that kind of soil called the L. fuliginatpr; Cerambyx fuligi· nator, L.; Oliv., Ih. X, 21. I~ is about six lines in length; black; elytra sometimes cinereous, and sometimes blackish· brown, each, in both cases, presenting three white lines, one along the suture, a second along the exterior margin, and a third between the two first, but not extending to their posterior extremity. Several other species are found in Germany and the south of Russi a( l ). In the other Lamiarire, the thorax is destitute of lateral tubercles or spines, and is cylindrical; the body is always elongated, and in some almost linear. They compose the genus SAPERDA, Fab.
