 elytra as described in the preceding species. Length, l§-2

In general appearance close to the preceding species, but 

 smaller, darker, the rostrum (especially in the male) less 

 curved, and the clothing denser and more variegated. Re- 

 garding it as (in my table) associated with philanthvm, it 

 differs in being smaller, paler, with the rostrum more curved 

 and the disproportion between the sexes less pronounced, 

 although still quite noticeable. If not associated with philan- 

 tlnun it would be with integricolle and carpophagum, each of 

 which is a larger species, with the male rostrum stouter, etc. 

 In length it is much the same as the South Australian 

 turbidvm, but it is wider, with slightly more curved rostrum 

 and paler legs. 



On the elytra there is a feeble transverse infuscate patch 

 •of pubescence about the middle, and immediately behind (and 

 usually before) the patch the clothing is paler and denser 

 than usual, so that the darker patch, although not very dark, 

 usually appears to be quite conspicuous. 



SUBFAMILY RHINOMACERIDES. 



AULETES. 



In this genus the rostrum of the male is usually shorter 

 than that of the female. 



In the table of the genus given in Proc. Linn. Soc, 

 New South Wales, 1898, p. 626, the fourth line ''Colour 

 entirely dark" should have been followed by a line '"'Colour 

 not entirely dark." 



AULETES MELAKOCEPHALUS, El\ 



This is probably one of the forms of suturalis, in which 

 case, as the older name, it will take precedence. I have 

 specimens of suturalis having the rostrum entirely dark, and 

 others having it dark only at the base. But in all of them 

 the suture is more or less distinctly infuscated : a char abd- 

 uct mentioned by Erichson, so that the two names may really 

 belong to distinct species. 



AULETES FILIROSTRIS, PasC. 



A specimen from the Swan River probably belongs to 

 this species, but the club of its antennas is infuscated only 

 instead of black, and in addition to its whitish pubescence 

 these are scattered about darker and semi-erect setae. Its
