PLATE EXT: 
ILLUSTRATIONS OF SOME SPECIES OF LONGICORN BEETLES FROM 
TROPICAL WESTERN AFRICA. 
Tue AfricanLongicorn beetles belonging to the section, of which 
Lamia regalis may be considered as the type, are amongst the most 
beautiful species of the entire group; and as our collections are 
particularly rich in them, I propose to devote a few Plates in the 
present volume of this work to their illustration. In the present 
Plate four new species are represented from the cabinets of the 
Rev. F. W. Hope, A. Melly, Esq., and my own collection. 
The species represented in Nos. 1, 2, and 3, belong to the genus 
Sternodonta of De Jean. This group was first pointed out and 
characterised by me ten years ago, in a paper published in the first 
volume of the Transactions of the Entomological Society of London, 
having been omitted by Serville in his revision of the Longicorn 
beetles. I forbore, however, to propose a separate name for the 
group, which was subsequently adopted by M. Perchéron, in the 
‘Genera des Insectes,” where the name of Sternotomis was given 
to it, which name must be adopted in preference to that proposed 
by De Jean, the characters of which were only for the first time 
published in the ‘‘ Histoire Naturelle des Animaux Articulés,” 
Vol. III., p. 474. 
The species represented in No. 4, belongs to the genus Tra- 
gocephala of De Jean and Serville. 
Species IL.—LAMIA (STERNOTOMIS), VIRESCENS, Hope MS. 
(Plate 69, fig. 1, and details.) 
L. nigra, eeneo-pulverulosa, capite, pronoto et elytrorum basi albo-virescenti fasciatis, his 
etiam maculis variis albo-virescentibus ornatis. 
Long. corp. lin. 16. 
Habitat apud Sierram Leonam. 
The head is deeply notched in front, with a streak down the 
middle of the face dilated towards the mouth, the labrum, some 
patches beneath the eyes, and a fascia which runs behind them 
entirely across the head, of a pale silvery green colour. The man-
