POLYPHRADES RAUI, n. Sp. 



Black; densely clothed witli snowy-white scales closely 

 applied to derm; with sparse thin setae on elytra, but more 

 numerous elsewhere. 



Read wide; eyes scarcely interrupting the general con- 

 vexity. Rostrum short, distinctly narrowed from base to apex, 

 apical triangle glabrous and with small distinct punctures, a 

 short carina behind it. Antennae short, five apical joints of 

 funicle transverse. Prothorax widely transverse, evenly 

 convex, sides gently rounded. Elytra subcordate, much wider 

 than prothorax, widest at about basal third; with rows of 

 large but almost concealed punctures. Legs moderately stout; 

 front tibiae moderately, the others lightly, denticulate; claw 

 joint of tarsi almost as long as the others combined. Length, 

 6 mm. 



Hob. — South Australia : Carraweena. Type (unique), I. 

 7960. 



The claw joint is unusually long and the claws are more 

 widely separated than is usual in Polyphrades, but they are 

 soldered together for about half their length; the species is a 

 rather aberrant one, and in some respects appears to approach 

 Onesorus. The type has not been abraded, but the elytra 

 appear to be uniformly convex with no striae, the seriate 

 punctures being isolated in the rows. To the naked eye the 

 insect appears pure white, except where a slight amount of 

 abrasion has revealed the black derm, but under a lens the 

 scales along the middle of the pronotum and about the elytral 

 suture appear somewhat slaty-grey.

P. satelles, Blackb., Cooper Creek. 



Leptops fumatus, Lea. 

 Two specimens from Cooper Creek differ from the types in 

 being somewhat smaller, and with conspicuously paler scales; 

 one of them has the tubercles more acute than on the type, 

 but on the other they are less acute. 



Leptops globicollis, Lea. 



Four specimens from Carraweena appear to represent 

 another variety of this species; they differ from the types in 

 being smaller, with the scales considerably paler (almost 

 white) and with the rostrum and tibiae not quite so stout.
