middle of base; shoulders advanced; rounded; sides lightly rounded. 



Length 9-10, breadth 4-5-5 mm. 



Hab. — -Mount Barker (Lea). 



This species may be distinguished from all other described 

 species which have vittate elytra by the following characters in 

 combination: — prothorax deeply emarginate at apex, not lobed at 

 base, three setigei'ous punctures on each side ; apical ventral 

 segment with only four setse. I believe it is the only species yet 

 described with the base truncate. The discoidal vitta on each 

 elytron does not curve inwards towards the suture at the apex; it 

 resembles that of P. distinguendus, Chaud., but is wider, not so 

 narrow at apex, and reaches nearer to the apex of the elytron.

Prothorax deeply emarginate at apex, wider between anterior 

 than between basal angles, five setigerous punctures on each side; 

 elytra subparallel, substriate, densely punctulate ; intermediate 

 tarsi of ^ with two basal joints squamulose beneath. Plead and 

 prothorax ferruginous-red; elytra piceous with a wide triangular 

 space extending backwards from base on disc and a narrow lateral 

 margin ferruginous; under surface and femora reddish-testaceous; 

 sides and apex of abdomen infuscate; antennse, tibia3 and tarsi 

 piceous-red. 



Head large, depressed, strongly constricted behind eyes; front 

 lightly punctulate; eyes prominent. Prothorax widely transverse 

 (1-6 X 2-9 mm.), widest before middle; sides subangulate at widest 

 part, lightly and roundly-obliquely narrowed anteriorly, obliquely 

 narrowed posteriorly with a wide faint sinuosity before posterior 

 angles ; lateral margins explanate, reflexed posteriorly, hardly 

 rugulose, three or four conspicuous setigerous punctures on 

 anterior half of each; anterior margin deeply emarginate; anterior 

 angles prominent, obtuse, projecting out almost as far as eyes; 

 posterior angles obtuse but marked ; base arcuate, projecting 

 a little backwards in middle, lightly sinuate on each side of
