Stenoserica delagoana, n. spec. 



Very pale testaceous and slightly iridescent ; head of the normal 

 shape, anterior margin of clypeus plainly sub-aculeate in the centre, 

 antennae 9-jointed, club 3-jointed, ovate in both sexes, and not much 

 longer in the male than in the female, slightly flavescent in the 

 male, reddish in the female; prothorax not distinctly punctulate ;. 

 scutellum faintly punctulate; elytra elongate, somewhat convex, 

 finely but not deeply punctato-striate with the intervals nearly 

 plane and faintly punctulate, and having along the suture and 

 each alternate interval a series of very remote but quite con- 

 spicuous bristle-like hairs. 



Length 7-7^- mm. ; width 3^—4 mm. 



Hob. Mozambique (Lourenco-Marquez). 



Stenoserica deceptor, Pering., 

 Trans. S. Afric. Philos. Soc, vol. vL, 1892, p. 35. 



This species differs from S. delagoana mostly in the colour, which 

 is either reddish or chestnut-red ; the club of the antennae is longer 

 in the male with the joints elongated, but not quite as long as the 

 pedicel ; the sculpture on the clypeus, head, prothorax, and antennae 

 is much deeper; the costules on the elytra are also much more 

 pronounced, and the intervals much more deeply punctured. 



Length 6-J- 7 mm. ; width 3J mm. 



Hab. Southern Rhodesia (Middle Limpopo) ; Ovampoland 

 (Omrramba). 



Stenoserica zambesicola, n. spec. 



Chestnut-brown, with the frontal part of the head and the pro- 

 thorax fuscous, glabrous, elytra opaque but with a slight opaline 

 sheen ; club of antennae flavescent, as long as the pedicel in the male ; 

 clypeus as long as the frontal part, slightly emarginate laterally r 

 slightly bi-sinuate in front owing to the anterior margin being 

 plainly acuminate in the centre, deeply and somewhat coarsely punc- 

 tured, frontal suture fine, very plain, and with the edges slightly 

 raised, frontal part sparsely punctate, the punctures round and 

 moderately deep ; prothorax moderately closely punctate and with- 

 out any lateral hairs, convex and with the posterior angles sharply 

 defined ; scutellum punctulate ; elytra one-third longer than broad,, 

 sinuate laterally in the anterior part, and plainly ampliate in the 

 posterior, punctato-striate with the intervals somewhat raised in 

 the anterior part ; under side iridescent, almost glabrous except
