nodnlo'^ns, n.sp. 



Sauagus Mastersi, n.sp. 



Widely ovate, convex, dark brown, slightly nitid, margins 

 paler, legs and underside nearly black. 



Head flat; epistorna arcuate in front, it.s angle.s blunt Wiit sub- 

 rectangular, sides straight and narrowing to ej'es without any 

 limiting suture at base; eyes separated by distance equal to the 

 diameter of one, surface coarsely granulated; antennae not reach- 

 ing base of prothorax, third joint as long as fourth and fifth 

 combined, with five apical joints thickened and round. Prothorax 

 (3 X 9'5 mm.), length measured in middle, width at base; circularly 

 emarginate at apex, anterior angles obtuse, enclosing head in 

 front of e3'es, sides arcuately widened to base, posterior angles 

 very sharp and deflexed, foliate margins wide and reflexed near 

 edge, width of combined margins to disc as 11 :8; edge (seen 

 sideways) laminate, surface of margins roughly and closely 

 granulated; disc slightly convex, closely rugose and scabrous. 

 Scutelluni curvilinear-triangular, finely granulose. Elytra wider 

 than prothorax at base, widest at middle, shoulders obtuse, foliate 

 margins wide but narrowing at apex, undulate at middle and 

 granulose; extreme margins thick and reflexed, edge (seen side- 

 ways) convex and much wider than edge of prothorax. Disc 

 very convex, bicostate, with two subparallel carinte extending 

 from base to apical declivity 3 mm. apart, these bordered on each 

 side with rows of large punctures; surface of disc coarsely, closely 



* P. alternattis Pasc. — If I am correct in my identification of species from 

 Queensland (Cloncurry and Roma), this species has a coarsely granulated 

 .sternum, the granules being large and round, rendering its recognition easy.
