Head strongly convex, rostral ridges not prominent. Prothorax 

 (7x7 mm.) moderately produced, collar-constriction well marked, 

 finely granulate, the granules being finer and closer together 

 in the centre. Elytra (16 x 10 mm.) elongate, base arcuate, 

 shoulders tuberculiform, striae somewhat irregular, crossed by 

 numerous low setigerous ridges; interstices irregularly granulate 

 in double series except on fourth and sixth. Metasternum 

 elevated on either side of middle, behind middle coxae. Anal 

 excavation reaching anterior margin of segment, preanal fossa 

 deep, rounded, the posterior edge of the segment forming a pro- 

 jecting ridge ending abruptlj^ on either side of the fossa; fascicles 

 close together, situated on edge of excavation. Forceps long, 

 evenly curved, tapering from base to apex; penis with the outer 

 angles produced outwards in a curved manner. Dimensions : 

 $, 23 X 10; 9, 23x10 mm.

Type in Macleay Museum. 



In general appearance close to P. squamigera Macleay, but 

 differing in the anal excavation and forceps. A widespread 

 species over the country lying along, and to the south, of the 

 main Western Line; to the north its place is taken by P. 

 squamigera. The more western specimens differ somewhat from 

 the eastern in the shape of the anal excavation; in the more 

 typical specimens (e.^., the Grenfell specimen) the projection 

 downwards of the posterior edge is much more marked than in 

 the western forms {e.g., the Narromine specimen), and the inner 

 ends of the projection come closer together so that the hiatus 

 between is more abrupt, and not so open.
