110 INSECTA. 
AcAntTHorTErA, Lat—Cauticuroma, Purpuricenus, STENocoRUS, 
Dej, Dalm. 
Certain species of America, in which the thorax is almost square, 
or nearly cylindrical, and the elytra are most frequently terminated 
by one or two spines, form the Stenocorus of Dalman™*. 
Others, but generally peculiar to the western countries of the east- 
ern continent, in which the body is‘tolerably elevated, the thorax 
almost globular, and the antennz are simple and without fasciculi of 
hairs, constitute the Purpuricenus of Ziegler and Dejean +. 
Another species with a depressed body, and in which the 
third joint of the antenne, and the three following ones are ter- 
minated by a little bundle of hairs, approaches the Callichrome, 
with which we formerly arranged it, in its general form and the 
musky odour it diffuses. Itis the A. alpina; Cerambyz alpinus 
L.; Oliv., Ib., 67, IX, 58; cinereous-blue; six blackish spots 
disposed longitudinally on each elytron, the two middle ones 
united and forming a band; a spot of the same colour on the 
anterior part of the thorax; superior part of the joints of the 
antenne also black. Common in the Alps; it is sometimes 
taken in the timber yards at Paris. 
The following Cerambycini have but eleven joints in the antenne. 
In some, at least in the males, the antenne are long and setaceous, 
the last joint of the palpi is obconical, the thorax is either almost 
square, and slightly dilated in the middle, or oblong and nearly cy- 
lindrical—it is frequently rugose and tuberculated on the sides. 
They compose the subgenus 
CERAMBYX, proper.—CERAMBYX, Lin., Fab. 
Certain species, with an unequal or rough thorax, usually spinous 
or tuberculated and dilated on the middle of its sides, with the third, 
fourth, and fifth joints of the antegne, evidently thicker than the 
following ones, thickened and rounded at the end; and the latter 
abruptly longer and thinner, almost cylindrical, forming, with the 
preceding ones, an abrupt transition, have been generically distin- 
guished by the name of Hamaticerus. The antenne are much longer 
in the males than in the females. 
C. heros, Fab.; Oliv., Ib., I, 1. Length one inch and a half; 
black; extremity of the elytra brown, and prolonged into a small 
tooth at the suture; thorax extremely rugose and with a pointed 
or spiniform tubercle on each side ; antennz simple, Common

culatus of M. Germar, which he refers to the Purpuriceni, is a Callichromas M. 
Sahlberg, professor of Nat. History, has described and figured this last Insect under 
the name of Cerambyx zonatus, in a work entitled Periculi Entomographici, Species 
Insectorum nondum descriptas propositurt fasciculus, with four plates. He then 
figures various Cucurlionites forming new genera, according to the system of M. 
Schenherr. The descriptions are modelled on those of M. Gyllenhall, and are very 
complete.
