rugae on the dorsal surface and sides ; on each side is a small 

 white spot near the middle, and there is a central white spot on 

 the hinder margin, and a transverse white line on either side. 

 The scutellum is white. The elytra are not quite three times the 

 length of the thorax, broadest at the base, and about one-fourth 

 narrower at the opposite extremity, which is armed with two 

 small spines, one being on the inner margin, and the other sepa- 

 rated from this but by a narrowish space. An oblique ridge 

 passes backward from the humeral angle of each elytron, and 

 almost reaches the apex, running obliquely inwards in its course ; 

 the space between the ridge and the suture is flat, or very 

 slightly concave. At the base, the elytra are rugose ; and, be- 

 yond, they are rather finely punctured. In the middle of each 

 elytron is an obliquely-transverse white band (descending as it 

 passes from the suture outwards), which is interrupted in the 

 middle j and very near the apex is a transverse white spot. The 

 antennae are rather longer than the body, including head and 

 thorax ; and so are the slender hind legs. 



Length, 8 lin. ; width, at base of elytra, 2 lin. 



Fam. LAMIAD.E. (Plate XVIII. fig. 8.) 

 Lamia cenea. (Parry). 

 Lamia nigra ; elytris asneis, nitidis, punctato-striatis ; articulis 



antennarum ad basin cinerascentibus. 

 Long. corp. lin. 14. Habitat Guinea. 



A new species of Lamm, belonging to the genus of Monohan- 

 mus, of Meguli ; it is from the environs of Cape Coast Castle. 

 For this and the following species I am indebted to my friend, F. 

 Swanzy, Esq., a resident in that country. The principal feature 

 in this species is the dingy brass colouring of the elytra. 



Gen. Mastigocera, Dej. 

 Mastigocera harh'icornis , Fab. (Plate XVIII. fig. 7.) 

 M. Thorace spinoso, elytrisque fusco nigroque variis, albo ma- 



culatis, articulo tertio fascicula pilorum. 

 Long. 13 lin. Habitat Guinea. 



The description by Fabricius corresponds so exactly with the 

 insect received by me from the same locality, that I have no 

 hesitation in presenting it to your notice as such. Although 

 previously described, yet, being a very rare and beautiful insect, 

 a figure of it must prove acceptable to the collector of foreign 

 Coleoptera.
