side with a pointed tubercle. It is an inch long, of an obscure 
black, with short antennz and granulated elytra. 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 larve probably feed on the roots of plants. 
These species form the genus Dorcapion of Dalman, which is 
adopted by most entomologists. The antenne 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. 
M. Megerle has formed the genus Parmena, with certain 
small species that appear to me to be removed from the others 
only by the antennz, which are longer than the body, and as 
their joints are more elongated, they become rather cylindrical 
than conical. According to this, we would be obliged to con- 
nect others with them, much larger, but presenting the same 
characters, such as the trisits, Jugubris, and fwnesta. 
Among those with short antenne, or the Dorcadions properly 
so called, there is one very common in Europe, but almost ex- 
clusively confined to calcareous localities, or to such as border 
on that kind of soil called the L. fuliginator; Cerambya fuligi- 
nator, L.; Oliv., Ib, X,21. Itis about six lines inlength; black; 
elytra sometimes ciner eous, 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 Russia *. 
In the other Lamiarie, 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 
Sarerpa, lab. 
That which he calls Gnoma, restricting it to certain species from 
Java, Sumatra, New Holland, &c., in the direction of the head, and 
in the parts of the mouth, resembles the Lamize; but the thorax is 
as long as the abdomen, cylindrical, somewhat narrower in the mid- 
dle, and destitute of spines and tubercles. The antenne are longer 
than the body, and are sometimes furnished with bundles of hairs. 
The anterior feet are elongated f. 
Count Dejean has detached from the Saperde the genera Apzs- 
mus, ApomEcynA, and CoLoBoTHeEa. 
The Adesmit only differ from the ordinary Saperdze in the first 
and third joint of the antenne, which are, proportionally, much more 
elongated; the length of these two joints, added to that of the inter- 
mediate one or the second, constitutes more than a third of the total 
length of the antenna.
