except that in the apical half the scales become much 

 smaller arid are widely separated. Ante/iiice red-brown, the 

 funicle with joint 1 lonojer than 2, 4-7 as long as broad, 

 3 a little longer. Protlioraw transverse (3 : 5), moderately- 

 rounded at the sides, broadest about the middle, sharply- 

 constricted at the base, and just in front of the constric- 

 tion on each side a very small, sharp, obliquely-projecting 

 point ; the apical and basal margins truncate and of about 

 the same width, the latter slightly raised ; the dorsum very 

 convex transversely, flat longitudinally, but sloping slightly 

 downwards in front, with a very narrow, faint, undulating, 

 abbreviated median carina ; the scales circular, contiguous 

 but not overlapping, almost entirely concealing the even 

 integument ; the broad flattened setge subrecumbent. 

 Elytra regularly oval, broadest about the middle, laterally 

 constricted at the base ; the basal margin jointly and 

 shallowly sinuate, the external angle produced obliquely 

 outwards into a small blunt projection; the dorsal outline 

 only gently convex, deepest about the middle ; the striae 

 feeble, the punctures (when the scaling is intact) appearing 

 very small and widely separated, each containing a minute 

 horizontal seta ; the intervals broad, flat, and smooth, each 

 with a row of Hattened subrecumbent setae, sometimes 

 duplicated ; the scales like those on the pronotum, but 

 more closely set and slightly overlapping. Legs densely 

 squamose, the tarsi red-brown ; the front tibiae with very 

 small inconspicuous apical spines, the hind pair with the 

 corbels bare. 



Length 3-5-3*9 mm., breadth 1-8-2 mm. 



Southern Rhodesia s Sebakwe (Z). Dodds). 



Described from five specimens. 



Superficially much resembling P. convexicollis, Fhs., but 

 in that species the rostrum is not carinate, the pronotum 

 has a median stria, the pronotum and elytra lack the basal 

 projections, and the elytra are much more broadly rounded 

 behind. 



Protostrophus cavirostris^ sp. n. (PL V. fig. 3.) 



^ ? . Integument black, with dense sandy or sandy-grey 

 scaling, which sometimes has a slight metallic reflection, 

 especially at the apex of the rostrum. 



Head separated from the rostrum by a deep curved furrow 

 which is almost entirely hidden by the scaling ; the fore- 

 head gently convex transversely, very finely wrinkled 

 longitudinally, but the sculpture entirely hidden by the
