Hyperacantha bituberciUata Fubr. 

 This species is placed in Diabrotica in Gemminger's Catalogue, and the "habitat" 

 of the species is given as Cai/eniw. Olivier gives Africa as its proper country, which 

 is correct. As far as I remember, a typical specimen of II. bitubcrculata is con- 

 tained in the British Museum, which proves that the species belongs to Hyperacantha. 

 It may be recognised by its uniform pale flavons coloration, the apex of the tibiae 

 and the tarsi alone are stained with piceons ; the nude has tlie usual tubercles near 

 the sutnre at the apex. The thorax is impunctate and the elytra have a dcej> 

 transverse depression below the base, and are rather strongly punctured. 1 have 

 seen specimens from Gaboon and Kuilu. 



Cneorane unicolor sp. nov. 



Elougate, convex, iiavous, above fulvous, shining ; thorax imjiunctate, snb- 

 <iuadrate, elytra extremely finely jiuuctured. 



Length 2J lines. 



Head broader than long, impunctate, shining, the frontal elevations entirely 

 obsolete, the clypeus narrowly transverse, eyes large, palpi robust, the terminal 

 joint as long as the preceding one, antennae not extending to the middle of the 

 elytra, fulvous, the second joint short, the third half the length of the fourth joint, 

 the following joints slightly shorter; thorax subquadrate, slightly broader than 

 long, the sides straight, the posterior margin rounded, the angles not ])romiuent, the 

 surface convex, smooth, shining, impunctate ; scutellum triangular ; elytra wider at 

 the base than the thorax, convex, reddish fulvous, the surface very shining, 

 microscopically finely punctured, their ejjipleurae very broad, continued to the apex ; 

 underside flavous, legs fulvous, tibiae unarmed, the first joint of the posterior tarsi 

 as long as the following two joints together ; claws appendiculate, anterior coxal 

 cavities open. 



Hab. Kuilu. 



One of the smaller species of the genus, but tyjiical in structure, and dis- 

 tinguished by its uniform coloration. 



Malacosoma dilatatum sp. nov. 



Ovate, widened medially, ]iiile flavous ; thorax transverse, the sides rounded, 

 the surface extremely finely punctured, elytra more distinctly but also finelv and 

 <'losely punctured. 



Length 3 lines. 



Head impunctate, the frontal elevations strongly raised, narrowly transverse, 

 the clj'peus with a distinct central ridge, palpi strongly iucrassate, the terminal 

 joint short, conical, antennae extending beyond the middle of the elytra, fulvous, 

 the third joint twice the length of the second but slightly shorter than the fonrtli 

 joint; thorax twice as broad as long, of equal width, the sides ratlior strongly 

 rounded at the middle, the anterior angles slightly produced outwards, the surface 

 without impressions, closely covered with very minute punctures ; scutellum 

 triangular ; elytra slightly more distinctly punctured than the thorax and as closely 

 so, their epipleurae indistinct below the middle : legs slender, all the tibiae 

 mucrouate, the first joint of the posterior tarsi as long as the following two j(»ints
