These characters give this genus a very different appearance from 

 Eutelus and the preceding one. The form of the prothorax causes a 

 marked distinction between the pronotum and its flanks, which is 

 wanting in the above genera ; the epipleurae of the elytra are also 

 of equal breadth throughout, and very apparent.

 Hab. Natal. 



Copper-brown, shining ; head finely punctured ; antennae reddish fer- 

 ruginous ; lip and palpi paler ; prothorax rugosely punctured, the sides 

 dark red ; scutellum small, transversely convex ; elytra coarsely and 

 sparingly punctured, narrower at the base than the prothorax, gi-adually 

 broader and higher near the middle, where they are a little rounded and 

 furnished with twelve tubercles, then almost vertically declivous, and 

 the sides rapidly narrowing to the dehiscent apex, where they termi- 

 nate each in an obtuse point ; body beneath and femora dark brown, 

 shining, finely punctured ; tibiae and tarsi reddish ferruginous. Length 

 5 lines.

The type of this genus is Adelium cupreimi, G. R. Gray (Griffith's 

 Animal King. Ins. ii. p. 22, pi. 80. f. 2). It is another of those 

 species allied to Projphanes, which M. Lacordaire considers not to 

 accord with that genus. It is in fact much nearer Cyplialeus in 

 form than the depressed Prophanes. Another genus to be consti- 

 tuted is one for P. metallescens, "Westw. ; and probably my Charto- 

 pteryx binodosus, with its two great humps like Thecacerus, will 

 require another. All the species of this handsome family, except 

 Lepispilus sulcicollis* and Hemicyclus grandis, are exceedingly rare. 

 My collection contains eleven species, the British Museum seven, the 

 greater part of each of each of them limited to a single individual. 

 There are doubtless many more to come.
