BY EUSTACE W. FERGUSON. 575 



Head convex, clothed with yellow scales intermingled with 

 setae. Rostrum short, ridges flattened, basal impressions shallow, 

 but with a well marked groove leading from median notch to 

 depression behind the marginal plate. Mentum bearded, dentate 

 anteriorly. Mandibles simple, densely clothed with yellow setse. 

 Pro thorax (6 X 6 mm.) evenly rounded on sides, median lobe 

 slightly produced, collar-constriction feeble, median line traceable 

 throughout; densely and finely granulate, granules contiguous, 

 €acli bearing a long, stout, decumbent seta. Elytra(14 x 8 mm.) 

 rather feeblj^ and evenly rounded on sides, strongly declivous; 

 apex mucronate, base widely emarginate, shoulders moderately 

 prominent; striate, stride broad, rather indistinctly divided into 

 foveaB by transverse setigerous ridges, interstices closely granu- 

 late in double series except on the fourth and sixth, and ends of 

 the second interstices, where they are in single series; sutural 

 interstices widened at base, and to less extent the third and fifth 

 also, granules fine, umbilicated, setigerous ; sides irregularly 

 granulate. Metasternum widely concave, moderately raised at 

 sides. Fifth ventral segment moderately deeply excavate, exca- 

 vation barely reaching to anterior margin; preanal fossa deep, 

 not very sharply marked off from rest of excavation; posterior 

 border fringed laterally with short hairs, supernumerary ridges 

 present at sides; fascicles small, moderately close(l mm.), situated 

 just within the edge of the excavation. Forceps short, thin, 

 with the blades turned on themselves near apex; lamina? very 

 long and curved, rather narrow near base, but broadening out to 

 apex, apices widely rounded, overlapping; forceps fringed along

Closely allied to P, Sloanei, but differing in its smaller size,

 minal fascicles are also much smaller than in that species, though 

 about the same distance apart. My specimen is from the Macleay 

 Museum, and bears a label *' S. Aust. ? "; it belongs to a group
