two conspicuous rows, commencing near the base and ter- 

 minating near summit of apical slope, six in the inner and 

 five in the outer row, of these the smallest is humeral ; there 

 is also a small but subcorneal tubercle half-way down the 

 apical slope. 



POLYPHRADES LONGIPENNJS, PaSC. 



This is an abundant and widely distributed species in 

 South Australia, and varies considerably in size (6-11 mm.) ; 

 its scales are usually ashen-grey, but vary to ashen-green, and 

 even to ruddy-golden ; the elytra with the fifth and seventh 

 interstices conjoined posteriorly so as to become costate to 

 apex, is its most distinctive (although not unique) feature. 



POLYPHRADES RUGTJLOSUS, Blackb., 9- 



Cherrus longuh&s, Blackb., <$ . 

 The types are in the South Australian Museum, and 

 "undoubtedly belong to but one species, of which rugulosus is 

 the female and Jongidus the male, although the latter was 

 referred to Cherrus on account of the rather long scape: of 

 the same length, however, as in rugulosus, which was 

 described as a "'typical" Polyphrades. It belongs to a group 

 of species that might be referred to either Polyphrades or 

 Cherrus; but perhaps are preferably regarded as of the 

 former. In addition to the type localities, specimens have 

 been taken at Kalgoorlie and Boorabbin. 



Polyphrades pictus, Blackb. 



In his table of PoVyphrades, l22) Blackburn distinguished 

 pictus and biplagiatus from the other species by "head very 

 conspicuously strigose longitudinally" — a character he did 

 not mention in the description. In biplagiatus, even before 

 abrasion, the head is seen to be quite strongly strigese ; but 

 on five co-types of pictus the striation was not conspicuous 

 before abrasion, although where the scales were intentionally 

 removed it was very evident. 



Polyphrades rostralts, Blackb. 

 Two specimens from Paringa differ from some co -types 

 of this species in having the clothing on the head and on the* 

 sides of prothorax and elytra metallic ; on one specimen there 

 are some brilliant green scales, forming a conspicuous line 

 from apex of prothorax to apex of elytra, the scales between 

 this line and the margins are more of an ashen-green. On 

 the second specimen most of the scales are golden-green or
