Species o/Curculioniilse from Africa. 373 



base ; the apical margin gently arcuate dorsally and very 

 oblique at the sides ; the basal margin not broader than the 

 apical, very slightly arcuate, almost truncate, with a deeply 

 impressed transverse line close to the edge ; the dorsum 

 strongly convex transversely and slightly so longitudinally, 

 the apex being lower than the base ; the coriaceous 

 sculpturing hidden by the scaling, except along a slightly 

 raised median line, which extends from the basal stria 

 to a little distance behind the apex ; the flattened setce 

 recumbent. Elytra broadly ovate, widest about the middle, 

 rather broadly rounded behind, the dorsal outline almost 

 flat, the hasal margin sinuate ; the stria3 very shallow, but 

 the punctures deep and distinctly visible through the 

 scaling; each interval with a row of numerous curved, 

 or slightly raised, flattened setse ; the scales not larger than 

 those on the pronotum. Legs with the tibice not denticulate 

 internally, the apical mucro inconspicuous, the front pair 

 with the. apical teeth stout and extending a short distance 

 up the external edge, the hind pair with the corbels dis- 

 tinctly enclosed, bare, the upper edge angulate at its base. 

 Sternum with the front coxa? in the middle of the presternum, 

 the centro-sternal piece forming a small tubercle. 



The $ smaller than the ? and a little narrower, and the 

 last ventral segment slightly shorter. 



Length 3'5-5 mm., breadth 1*6— 2"25 mm. 



S. Uhodesia : Buluwayo, xii. 1903 (G. A. K. M.). 



Very similar in appearance to P. (Strophosomus) corwexi- 

 collis, Fhs., but in that species there is a median furrow on 

 the pronotum and at the apex of the rostrum. 



So far as is known at present, Southern Rhodesia appears 

 to be the northern limit of the genus Protostrophus. The 

 present species was the only one met with at Buluwayo, and 

 P. mucrvnalus was the only species found at Salisbury 

 during many years' collecting. Further south the species 

 are numerous, but 1 have seen none from the western 

 districts of the Cape Province. 



Protostrophus carinirostris, sp. n. 



$ . Colour black, densely clothed with small, almost 

 round scales, slightly overlapping in parts, those on the 

 pronotum being distinctly larger than those on the elytra. 

 Scaling on head and rostrum grey, with the costse brownish; 

 pronotum grey, with a broad median brown stripe ; elytra 

 mottled with fawn, grey, and brown, interval 1 entirely fawn,
