118 INSECTA. 



The Apomecijnre* have a cylindrical body; the antennae 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 Lamiae, and Fabricius places one of them, 

 the histrio, in that genus. 



The Colobothece, which include the major part of his Stenocori, 

 have their antennae 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 a long 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 f. 



Other Saperdae, and all from Brazil, in Avhich the thorax is as wide 

 as the elytra, or scarcely narrower; in which the third and fourth 

 joints of the antennae, 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 J. 



Several Saperdae, with an always long and narrow body, on account 

 of their antennae, which are composed of twelve joints and not of 

 eleven, should also form a particular subgenus §. 



Of those species, considered by all the entomologists of the day 

 as Saperdae properly so called, we will cite the two folloAving: 



S. carcharias ; Cerambyx carcharias, L.; Oliv., lb., 68, ii, 22. 

 An inch long, covered with a cinereous-yellow down punctured 

 with black, and the antennae 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., lb., 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 antennae are excessively long and almost as 

 slender as a hair 11.

•f- Ibid. The Sfenocorus pictus, — Oliv., Saperde, 68, iv, 40, — anmilaius of Fabri- 

 cius. His Saperda acuminata appears to belong to the same genus, as well as the 

 Insect figured by Olivier among the Cerambyces, pi. xvi, 117, although its thorax is 

 bi-spinous. 



X Such are the Saperda amicfa, fngafa, palliata, dascyera, ciliaris, of the Entom. 

 Bras., Kliig. The genus Tht/rda of Dalman — Anal. Entom., p. 171, vol. Ill — ap- 

 proximates in some respects to these species, but in others seems to approach the last 

 of our Prionii. 



§ The Saperda cardui, asphodeli, suiuralis, &c. In some of the preceding species 

 the eleventh and last joint is somewhat abruptly attenuated, but without being really 

 divided into two. 



II See Fabricius, Olivier, Schoenherr, and the Catalogue, &c., of Count Dejean.
