 dense variegated clothing, and with more or less erect dark

Antenna long and thin. Frothoiru: longer than wide, 

 widest at apical third ; with dense, normally concealed punc- 

 tures. Elytra rather long, shoulders rounded, thence to

Hah. — Victoria: Wangaratta (A. M. Lea). 



In general appearance somewhat like a large specimen of 

 P. attritus, but differs in having the shoulders much less 

 rounded (much like those of P. eminens or P. exulans, whilst 

 in /'. attritus they resemble those of the introduced /'. tec- 

 tus) ; the glabrous space between the subbasal and postmedian 

 clothing larger, and more perfectly glabrous ; the pubescence 

 rather more compact and more prettily variegated, and the 

 erect setae rather shorter. 



On the prothorax, the clothing is mostly dark brown, 

 almost black, and in four longitudinal ridges or fascicles, but 

 with a conspicuous white median line, and a white, variegated 

 with golden, basal line; on the scutellum, it is white; on the 

 elytra, on the basal fourth, it is white, variegated with 

 golden, then to beyond the middle the surface, except for a 

 few erect setae, is glabrous ; then there is a conspicuous white 

 fascia not quite touching the suture or sides ; on each side of 

 the suture commencing at the fascia, extending to the apex, 

 and then directed along the sides almost to the fascia, the 

 clothing is golden, the enclosed spaces being almost glabrous. 

 On the head, there is a narrow median line of whitish cloth- 

 ing, and the eyes are somewhat indistinctly encircled with 

 white.
