interval 3 with a more conspicuous grey spot behind the 

 middle, and a similar one a little in front of it on interval 5 ; 

 lower surface grey. 



Head separated from the rostrum by a gently curved 

 furrow, almost plane between the eyes, with a very broad 

 and deep median furrow ascending to the vertex, flanked by 

 a low costa and two more on each side of it (sometimes 

 traces of a third) ; e-, es very prominent and strongly pro- 

 duced backwards, deepest well behind the middle, the or hit 

 narrow and not projecting behind. Rostrum a little shorter 

 than its basal width, the lateral dorsal edges distinctly 

 sinuate behind the antennae and rather overhanging the 

 sides ; the dorsum strongly tricarinate, the outer carinas 

 nearer at the base to the median one than to the sides, and 

 gradually curving outwards to join the lateral margins above 

 the antennas ; the genae rather broadly and deeply impressed. 

 Antenna piceous, rather densely squamose ; the funicle with 

 joint 1 about one-fourth longer than 2, the remainder bead- 

 like, 3 a little longer than broad, 4 to 6 about as long as 

 broad, 7 broader and transverse. Prothorax twice as broad 

 as long, widest about the middle, the sides strongly rounded 

 and deeply constricted close to the apex ; the base arcuate, 

 scarcely marginate, and much broader than the apex, which 

 is shallowly sinuate dorsally and vertical at the sides ; the 

 rather rugose sculpture of the upper surface is hardly 

 noticeable through the scaling, and a fine bare median 

 carina runs from the base almost to the apex; the narrow 

 flattened seta? entirely recumbent. Elytra broadly ovate, 

 the sides slightly rounded, widest rather behind the middle, 

 broadly rounded behind, and jointly sinuate at the base, the 

 dorsal outline gently convex and continuous with that of 

 the pronotum ; the broad shallow sulci containing pupillate 

 punctures that are perceptible through the scaling ; the 

 intervals convex, and each with two irregular rows of short 

 recumbent setae. Leys stout, densely squamose; the tibiae 

 not denticulate internally, and the mucro inconspicuous ; 

 the corbels of the hind pair narrowly enclosed, squamose, 

 with the upper edge strongly angulate at the base. 



Length 5-5*4 mm., breadth 2*75-3 mm. 



Natal : Frere, 1892 (G. A. K. M.). 



Described from four specimens. 



Most nearly allied to P. {Strop ho somvs) sulcatifrons, 

 Mshl. (Proc. Zool. Soc. Loud. 1906, p. 914, pi. lxvi. fig. 2), 

 which lias the head and rostrum very similarly sculptured; 

 but, apart from being nearly twice as large, that species has
