at the anterior corners, and two smaller foveae at base, clearly 

 but not deeply punctate. Scutellum curvilinear-triangular. 

 Elytra 19 x 10^ mm., very convex, wider than prothorax at base, 

 shoulders widely rounded, widest in front of middle, and gradu- 

 ally tapering, without sinuation, to the apex, narrowly bordered 

 and channelled, the channel subobsolete at apex; each elytron 

 with ten rows of large, round, very deep punctures, separated 

 longitudinally and transversely by convex intervals, forming 

 promiscuous reticulations, besides a short scutellary row of 

 smaller punctures, and an abbreviated row of similar size to 

 these between the 3rd and 4th series; also a lateral row on 

 extreme sides, almost concealed by the channel, all the series 

 subobsolete at apex, the punctures in series often confluent or so 

 closely placed as to give the appearance of lying in deep sulci. 

 Epipleurce smooth, apical segment of abdomen finely punctate, 

 the basal segments striolate and coarsely punctate, sides of meta- 

 sternum pustulose, their episterna rugose-punctate; prosternum 

 carinate, produced and rounded behind; tibiae with a short spine, 

 hind tarsi with basal and apical joints of equal length. Dimen- 

 sions, 25 x 10 J r mm. 



Hab. — Brisbane; also New South Wales 



The elytra are described as " coeruleo-nigris " in Westwood's 

 laconic diagnosis of ten words. He also gives "Melbourne" as 

 the habitat, while its dimensions are given as " magnitudo P. 

 simplicis." 



It is nearest P. creber Blackb., the type af which, in the Mel 

 bourne Museum, has been lent me for examination, through the 

 courtesy of Mr. Kershaw. P. creber differs in the following 

 particulars : larger size, less convex, colour nitid bronze, eyes 

 not bordered by carina, head and pronotum less strongly punc- 

 tate, the lateral border of the latter uniformly thickened, its 

 sides sinuate; elytra without scutellary row of punctures, the 

 punctures in series smaller; there are about fourteen rows, the 

 lateral series ill-defined; but all are continuous to apex (no 

 abbreviated row), and nowise reticulate, or sulcate, inter multa 

 alia.
