184 REVISION OF PTEKOHBL^US (coiltd.) AND SARAGUS, ETC., 



narrow, extreme border very fine and scarcely raised, base 

 trisinuate with two equidistant foveae, and two smaller fovese, 

 one on each side of scutellum : disc convex, finely and rather 

 closely punctured, with central depression faintly indicated 

 near the middle. Scutellum semicircular. Elytra three and 

 one-half times the length of prothorax, and a little wider 

 than it at base, sides parallel to half-way, then slightly ex- 

 panded before the apex ; shoulder obtuse, margins very nar- 

 row (narrower than in P. vicarins Pasc), extreme border 

 raised, disc seriate-punctate with about 18 rows of close, 

 well-defined, round punctui'es, increasing in size from the 

 suture outwards, besides some irregular smaller punctures on 

 basal area ; of these rows, the punctures in the first (exclud- 

 ing a short scutellary row of similar punctures) very fine and 

 close, in the second and succeeding rows larger and more 

 distant, the lateral row of punctures largest of all and 

 deeply impressed ; the intervals flat on disc, but becoming 

 raised and convex towards the sides. Frosternn??i strongly 

 carinate and produced backwards into the mesosternum in a 

 wide V-shaped receptacle : meta- and episterna rather thickly 

 studded with large punctured pustules, those on the former 

 curved (or slug-shaped), on the latter round; abdomen with 

 first two segments strongly longitudinally strigose and punc- 

 tate, apical segment closely pvmctate only ; fore tibiae finely 

 serrated on their outside edge, armed at apex with two short 

 acute spines : tarsi clothed with pale red hairs. Penis 

 grooved above and terminated by four minute spine-like pro- 

 cesses. Dimensions, 16 x 8-5 mm. 



Hub. — Goombungle, Darling Downs, Queensland. 



A single specimen ((^) sent by Mr. C. French. It is most 

 closely allied to P. vicarius Pasc, from which it differs inter 

 alia by the more regularly defined seriate punctures of the 

 elytra, and in the sculptui-e of the sternum. In P. vicarius 

 Pasc, the sternvim is closely and regvilarly pustulose, the pus- 

 tules being little raised : in P. stenialis the pustules are much 

 larger, more distant and more defined. P. fjeminatns Blackb.,
