interval 3 with a more conspicuous grey spot behind the 

 middle, and a similar one a little lu frout 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 tlie vertex, flanked by 

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

 traces of a tliird) ; ejes very prominent and strongly pio- 

 duced backwards, deepest well behind the middle, tlie orbit 

 narrow and not projecting beliind. Rostrum a little shorter 

 tlian its basal width, the hiteral dorsal edges distinctly 

 sinuate behind the antennae and rather overhanging tiie 

 sides ; the dorsum strongly tricarinate, the outer carinse 

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

 gradually curving outwards to join the lateral margins above 

 the antennse ; the gense 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. Prothurax twice as broad 

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

 and deeply constricted close to the apex ; the ba.^e arcuate, 

 scarcely marginate, and much broader than the apex, wliich 

 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 setse 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 ; tlie 

 intervals convex, and each with two irregular rows of short 

 recumbent setse. Legs stout, densely squamose ; the tibise 

 not denticulate internally, and tlie 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.

Most nearly allied to P. {Strophosomus) sulcatifrons, 

 Mshl. (Proc. Zool. Soc. Lond. 1906, p. 914, pi. Ixvi. fig. 2), 

 which lias the head and rostrum very similarly sculptured; 

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