depressed below the base, rather regularly punctate-striate, the punc- 

 tures much stronger at the sides, the interstices finely pubescent, 

 purplish, the sides occupied by a golden cupreous band from the 

 shoulders to the apex, below and the legs nearly black, the anterior 

 and posterior femora widened, with a very minute tooth ; prosternum 

 broad, claws bifid. 



Hah. Cape. 



I possess a single specimen of this well-marked species 

 which agrees with Macetes in everything except the nearly 

 unarmed femora, but as this character is often variable I 

 have thought it best not to remove the species from the 

 genus. 



Nerissus tuberculatus, sp. n. 



Greenish-black below, legs piceous, above greenish, clothed with 

 yellowish hairs, thorax finely rugose, the lateral margins denticulate, 

 elytra transversely rugose with numerous small black tubercles, 

 metallic greenish. 



Length 8 millim. 



Head elongate, greenish -black, finely punctured, clothed with 

 yellow hairs, sides of the clypeus raised, its anterior margin straight, 

 labrum fulvous, mandibles robust, antennas extending to the middle 

 of the elytra, blackish, rather robust, the third joint one half longer 

 than the second, terminal joints twice as long as broad, thorax about 

 one half broader than long, transversely subquadrate, rather flattened, 

 the lateral margins rounded and finely denticulate, the surface closely 

 and strongly punctured, clothed with yellow hairs, the ground colour 

 greenish, submetallic, scutellum subpentagonal, pubescent, elytra of 

 a more decided green colour than the thorax, transversely rugose and 

 covered with numerous shining small tubercles, the interstices deeply 

 punctured and not very thickly clothed with yellow adpressed pubes- 

 cence, and more sparingly with stiff erect black hairs, below nearly 

 black, sparingly pubescent, legs piceous, the intermediate and the 

 posterior tibias emarginate at the apex, claws bifid. 



Hab. Cameroons. 



The single specimen I possess of this species differs from 

 any of its allies in the tuberculate elytra and the not very 

 close pubescence, the former are not very highly raised, but 

 very distinct, black and shining.
