118 INSECTA. 
The Apomecyne* have a cylindrical body; the antenne are fili- 
form, short, terminated by an acute point, and with the third and 
fourth joint very long, and the following ones extremely short. These 
species are peculiar to the East Indies and the Isle of France. They 
are closely allied to the true Lamiz, and Fabricius places one of them, 
the histrio, in that genus. 
The Colobothee@, which include the major part of his Stenocori, 
have their antenne closely approximated at their insertion, the body 
compressed, and as if carinated laterally, and the elytra emarginated 
or truncated at the end, with the exterior angle prolonged in the 
manner of a tooth or spine. The thighs are clavate and pediculated. 
The face forms along square. These Insects are peculiar to South 
America and to the most eastern islands of Asia that are situated in 
the vicinity of the equator+. 
Other Saperdze, and all from Brazil, in which the thorax is as wide 
as the elytra, or scarcely narrower; in which the third and fourth 
joints of the antennz, or at least the preceding one, are much elon- 
gated or dilated, and furnished with hairs, and the last ones are ab- 
ruptly shorter; and where the elytra are widened and rounded at the 
end, form another division t. 
Several Saperdze, with an always long and narrow body, on account 
of their antennze, which are composed of twelve joints and not of 
eleven, should also form a particular subgenus§. 4 
Of those species, considered by all the entomologists of the day 
as Saperdze properly so called, we will cite the two following: 
S. carcharias; Cerambyz carcharias, L.; Oliv., Tb., 68, 11, 22. 
An inch long, covered with a cinereous-yellow down punctured 
With black, and the antennz picked in with black and grey. 
Its larva lives in the trunk of the Poplar, and sometimes de- 
stroys young plantations of that kind of tree. 
S. linearis; Cerambyx linearis, L.; Oliv., Ib., ii, 13.- About 
six lines long; very narrow, linear; black; legs short and yel- 
low; elytra punctured in lines and truncated at the extremity. 
Its larva inhabits the Hazel-tree. 
Other species have been described in which the body is still 
narrower, and the antennze are excessively long and almost as 
slender as a hair |}.

+ Ibid. The Stenocorus pictus,—Oliv., Saperde, 68, iv, 40,—annulatus of Fabri- 
cius. His Saperda acuminata appears to belong to the same genus, as well as the 
Insect figured by Olivier among the Cerambyces, pl. xvi, 117, although its thorax is 
bi-spinous. 
$ Such are the Saperda amicta, togata, palliata, dascyera, ciliaris, of the Entom. 
Bras., Kliig. The genus Thyrsia of Dalman—Anal. Entom., p. 171, vol. I1I—ap- 
proximates in some respects to these species, but in others seems to approach the last 
of our Prionii. 
§ The Saperda cardut, asphodeli, suturalis, &e. In some of the preceding species 
the eleventh and last joint is somewhat abruptly attenuated, but without being really 
divided into two.
