preceding ones taken together, and is without an appendage bearing 
two sete between the hooks. The Spondyles are also distinguished 
from the following genera by their almost globular thorax, the mar- 
gin of which is neither recurved nor furnished with teeth or spines. 
Their larve live in the interior of the European Pines and Firs. 
S. buprestoides ; Attelabus buprestoides, L.; Oliv. Col. IV, 71, 
i, 1. From six to seven lines in length; black; densely punc- 
tured, with two elevated and longitudinal lines on each elytron, 
These lines are sometimes obliterated, and the individuals in 
which this occurs are considered by some entomologists as form- 
ing a separate species—the e/ongatum. No others are known*. 
In the third and last genus of this tribe, or 
Prionus, Geoff. Fab. Oliv., 
The antenne are longer than the head and thorax, serrated or pec- 
tinated in some; simple, attenuated near the extremity, and with 
elongated joints in others. The terminal lobe of the maxille is at 
least as long as the two first joints of the palpi. The body is gene- 
rally depressed, and the thorax square or trapezoidal, and either den- 
tated or spinous, or angular laterally. 
These Insects only fly towards evening or at night, and always re- 
main on trees. Certain species, foreign to Europe, are remarkable 
for their great size, and that of their mandibles. The larva of the 
P. cervicornis, which lives in the wood of the Gossampinus, is eaten. 
This genus comprises a considerable number of species, which, 
from the difference in the form and size of their mandibles, antenne, 
thorax and abdomen, might constitute several small groups or sub- 
genera. 
We might, in the first place, separate those species in which the 
body is straight, elongated, or forms a parallelopiped; the thorax 
is much shorter than the abdomen, square or trapezoidal, and strongly 
arcuated laterally; the scutellum is small or moderate; the antennz 
are simple or but slightly serrated, and the mandibles frequently 
Jarge in the males. 
Among the species of this division, with mandibles shorter than 
the head, the antenné almost setaceous, tolerably long, and composed 
of eleven joints, the third of which is much longer than the following 
ones, we find the 
P. seabricorms, Fab. Oliv., Col. IV, 66, XI, 42. Length an 
inch and a half; antenne bristled with small spines; a single 
tooth on each side of the thorax formed by its posterior an- 
glest. 
Other species, generally less oblong and slightly inclined before, 
in which the mandibles are always moderate, or project but little in 
both sexes, with the thorax strongly dentated laterally; where the
