Va7\ Legs black, the base of the femora fulvous. 



Length S-Sj millim. 



Head broader than long, the epistome not separated from the 

 face, eyes large, entire, the surface finely rugose, clothed with 

 whitish pubescence, labrum fulvous ; antennse long and slender, 

 fulvous, the basal joint short and thick, the second and third 

 subequal, shoi't, the others elongate, terminal joints slightly 

 tipped with piceous ; thorax short, quite twice as broad as long, 

 the sides feebly rounded, the surface sculptured and pubescent 

 like the head ; scutellum subquadrate, densely pubescent ; elytra 

 convex, subcylindrical, black, opaque, closely and finely punctui'ed 

 in rows, pubescent like the thorax ; legs fulvous. 



Ilab. Estcourt, ISTatal. 



Nerissella, gen. n. 



Oblong, pubescent ; head elongate ; the epistome not separated ; 

 antennse short, the terminal joints transversely widened ; thorax 

 narrowed anteriorly, with distinct lateral margins ; scutellum sub- 

 quadrate, its apex nearly truncate ; elytra irregularly punctured, 

 closely pubescent ; femora thickened, unarmed, tibiae dilated at 

 the apex, claws bifid ; anterior margin of the thoracic episternum 

 concave ; presternum broad. 



The species for which this genus is proposed will best find its 

 place amongst the Pseudocolaspince on account of the structui'e of 

 the antennae, pubescent upper surface, non-emarginate tibia?, bifid 

 claws, and the shape of the thoracic episternum. The genus diflf'ers 

 from Pseudocolaspis proper in the distinct and entire lateral 

 margins of the thorax and unarmed femora, from Palesida Har. 

 in the entirely different shape of the head and thorax, these 

 difierences also separating the genus from the other members of 

 the group. 



Nerissella curculionoides, sp. n. 



Greenish seneous, clothed with white pubescence ; antennse 

 blackish, head and thorax closely punctured ; elytra subelongate, 

 punctured like the thoi'ax, clothed with long whitish pubescence. 



Length 4 millim. 



Head elongate and narrowed in front, convex, without any 

 depressions, closely punctured, with short pubescence ; the epistome 

 not separated, its anterior margin semi circularly emarginate ; 

 eyes rounded, entire ; antennse widely separated, inserted below 

 the eyes, not extending to the base of the thorax, the terminal 

 five joints bluish black, transversely thickened, the other joints 

 obscure fulvous, the second joint thickened, longer than the thii'd 

 and following joint ; thorax about one-half broader than long, 

 narrowed anteriorly, closely and strongly punctured, and clothed 

 with rather long, adpressed, white hairs ; scutellum broad, its apex 

 nearly truncate ; elytra slightly wider a,t the base than the thorax, 

 oblong, nearly parallel, sculptured and pubescent like the thorax ;
