116 IXSECTA. 



Lepeletier and Serville — Encyc. Method., X, 545. The antennae of 

 the males are inserted into a posterior extremity of a long appendage 

 which arises from the lateral margin of the forehead, extends trans- 

 versely, and covers the eyes. 



All the species kaown are from Brazil. 

 Others of a very similar form, with antennae either bearded or fur- 

 nished with bundles of hairs, constitute the genus Pogonochkrus, 

 Meg. Dej. 



Some of the species inhabit Evirope, and nearly all of these are 

 remarkable for their elytra, which are truncated obliquely at the 

 extremity *. 



Others again, still slightly elongated, but with a more cylindrical 

 body, have each eye completely divided into two parts by the tu- 

 bercle which gives rise to the antennae — they compose the genus 



TETRAOPESf. 



Certain Lamiae of Fabricius, with a narrow and elongated body, 

 very long antennae, and a stout spine on each side of the thorax, in 

 Avhich the anterior tibiae are slightly curved, and the intermediate 

 ones are furnished with a tooth on the outer side, form that of the 

 MoNOCHAMus, Dej. — Monochammus, Dahl., Catal.; as those gentle- 

 men have not indicated its characters, 1 only give the above for such 

 as I presume them to be \. 



In the " Catalogue de la Collection des Coleopteres" of Count 

 Dejean, with the exception of the apterous species, the remaining 

 Lamiae of Fabricius retain the generic appellation of Lamia; but it 

 appears from another Catalogue, that of Dahl, that two species from 

 France — cucurlionides, nebulosa — have been separated by M. Me- 

 gerle to form another generic section, or Mesosa§; if we suppose 

 that the Saperdae differ from the Lamise in the absence of lateral 

 points on the thorax, these species in this respect would approach the 

 Saperdae; but their body is proportionally shorter and wider than 

 that of these last Insects, and by this character they are more nearly 

 allied to the Lamiae. Of these tAVO species, that called 



L. cucurlionides. Fab.; Oliv., lb., IV, 67, x, 69, is one of the 

 prettiest that is found in France. It is about six lines in length, 

 brown, with round, black, A'illous spots surrounded by a ferru- 

 ginous circle, which induced Geoffroy to term it the Lepture aux 

 yeux depaon. 



L. textor; Ceramhyx textor,L.; Oliv., lb., vi, 39. Another 

 species very common in Europe, but its thorax is armed on each 



* See Catalogue, &c., Dej., p. 107. 



t See Schoenh., Synon. Insect., and the Catal., Dej. The Ceramhyx maxillosus, 

 and nigripcs of Olivier appear to approach these Insects.

§ Another might have been formed with the Lamia hyslrix. Fab., whose antennae 

 are pectinated. There are some, such as the L. 5-fasciuta, 3-fasciata, capensis, Sec, 

 in which the sides of the thorax are rather rugose or plicated, than furnished with 

 spines. Others, such as the species called the pulchra, regalis, iinperialis, oculator, 

 are rather more shortened and widened.
