emai'ginate and the upper surface is glabrous ; the genus is there- 

 fore transitional between these and allied groups. 



Cheiridella ZAMBESI an a, sp. n. 



Fuscous or fulvous, underside black ; head and thorax clothed 

 with fine grey pubescence ; elytra similarly pubescent, finely 

 punctured in closely approached rows. 



Length 5 millim. 



Head finely rugose, the epistome not separated; eyes ovate, 

 entire ; antennae slender, fulvous, the basal two joints thickened, 

 the third slightly longer, shorter than the following joints, ter- 

 minal ones scarcely thicker ; thorax twice as broad as long, of 

 very nearly equal width, the sides rounded at the middle, slightly 

 constricted at the base and apex, the angles not produced, the disc 

 rather convex, black, closely covered with greyish pubescence, the 

 interstices finely granulose ; scutellum scarcely broader than long, 

 its apex obtusely rounded ; elytra not wider at the base than the 

 thoi-ax, slightlj^ widened posteriorly, convex, opaque, closely and 

 extremely finely punctured in rather ill-defined rows and clothed 

 with long greyish pubescence ; underside slightly more shining ; 

 the femora rather thickened, the anterior ones with a distinct 

 tooth, the others very minutely dentate. 



Hah. Estcourt, Natal. 



In one specimen the legs are black, with the exception of the 

 base of the femora which is fulvous and the tarsi are feeble 

 and slender ; but in another, pi'obably the male, they are slightly 

 broader. 



Casmenella, gen. n. 



Subelongate, convex, pubescent ; antennae filiform, the second 

 joint shorter than the third ; thorax twice as broad as long, 

 slightly constricted anteriorly and posteriorly, with distinct latei'al 

 margins ; elytra finely punctured in rows, pubescent ; femora 

 thickened, the anterior with a distinct tooth ; tibiae scarcely sul- 

 cate, the intermediate slightly emarginate at the apex, claws bifid ; 

 prosternum veiy narrow, the anterior margin of the thoracic 

 episternum concave. 



This genus will enter the Heteraspince of Ohapuis' arrangement, 

 and is very nearly allied to Gasmena Chap., but clifi"ers in the 

 strongly transverse thorax, the much shoi-ter femora, and the 

 absence of the long tooth with which the posterior femora are 

 provided in Gasmena. In Gasmena the thorax is scarcely one- 

 half broader than long. In Gasmenella the intermediate and 

 posterior femora have a very minute tooth, but that of the anterior 

 femora is well developed. 



Casmenella natalense, sp. n. 



Black, opaque, clothed with fine white pubescence ; antennae 

 fulvous, thoracic punctuation finely rugose ; elytra with very fine 

 rows of punctures and adpressed whitish hairs ; legs fulvous.
