front behind marginal plate. Mandibles with external angles 

 produced into two strong divergent horns. Prothorax(6 x 6 "5 mm.) 

 gently rounded on sides, • anterior margin sinuous at sides, 

 practically no median lobe; disc depressed in centre, median line 

 somewhat ill-defined; granules abraded in disc, traceable though 

 flattened on sides, along basal margin, and along the position of 

 the collar-impression; setse minute. Elytra(15 x 10 mm.), sides 

 rounded, dilated posteriorly, widest behind middle; apical flange 

 prominent, apex mucronate; base truncate, humeral angles 

 rectangular, not produced. Disc foveo-striate, fovea3 deep, 

 regular, transverse, separated by well defined transverse costse; 

 interstices costate, second, third, and fifth most prominent, 

 sutural slightly thickened at base, not joining third; second and 

 fourth showing tendency to be broken up into granules on the 

 declivity, costee sparingly setigero-punctate. Sides regularly 

 foveate in two stride. Metasternum feebly convex, almost flat. 

 Fifth ventral segment deeply and widely excavate as far forwards 

 as the anterior margin; preanal fossa deep, separated anteriorly 

 by a well defined edge extending across middle line; fascicles 

 small, about 15 mm. apart, situated within excavation; posterior 

 edge strongly sinuous. Forceps moderately long, evenly curved, 

 and meeting at apex; laminae small, rounded at apex, and fringed 

 with black hair along outer side. Legs moderately long, nigro-

Hah. — Queensland : Darling Downs(R. Illidge). 



Most closely allied to P. Carteri, but a smaller species, with 

 the elytral sculpture somewhat different, and diflPering widely 

 in the size and position of the abdominal fascicles, I am 

 indebted for my unique specimen to the generosity of Mr. R-. 

 Illidge, Brisbane.

 fascicles widely separated, forceps moderately long. Black,
