golden, many on the sides being brilliantly metallic; on the 

 upper part of its elytra, however, there are many obscure 

 patches of chocolate-brown scales. 



POLYPHRADES FORTIS, Blackb. 



There are nine specimens before me (varying in length 

 from 10 to 16 mm.) that evidently belong to this species, 

 which appears to be a singularly easily abraded one, as six of 

 them have the upper-snrface almost entirely glabrous, on the 

 elytra a few scales remaining only on the sides and apex. 

 A specimen in perfect condition has the whole of the upper- 

 surface closely covered with small round ashen scales, but 

 with a slight metallic gloss in places; on the apical slope of 

 its elytra there are some short setae (even these are missing 

 from the other specimens), and the sides for the space of three 

 interstices (as on the type) are densely clothed with pale 

 scales. The other two specimens are too dirty for their 

 clothing to be noted. The type was from Victoria, those 

 before me from Murat and Streaky Bays and Norseman. 



A specimen from Kuminin (Western Australia) probably 

 also belongs to the species ; its clothing is much as on the 

 perfect specimen, but the five rostral carinae are much less 

 conspicuously elevated and shorter (they vary, however, on 

 the nine specimens), and many of the elytral punctures are 

 transversely connected, the connecting depressions often 

 extendino - across three or even more interstices ; on two of 

 the other specimens, however, there is an evident tendency 

 to this structure, but on most of them the punctures are 

 completely isolated. 



POLYPHRADES UXIFORMIS, Lea. 



Some specimens from Mullewa and Geraldton of this 

 species are more conspicuously variegated than the types ; 

 they have three vaguely infuscated lines on the prothorax ; 

 on the elytra there are numerous patches of golden-red scales 

 set amongst sooty-brown ones, on others the paler spots are 

 of a dingy greyish-white. One specimen from Coolgardie at 

 first glance appears to have very dingy scales on the elytra, 

 but on close examination they are seen to be of a beautiful 

 golden-rose colour on the upper-surface, changing to pale 

 golden-green on the sides. 



POLYPHRADES LATUS, Lea. 



Four specimens from the Stewart River (Queensland) 

 differ from the types in being much smaller (4-5 mm.).
