as densely clothed on the suture as on the median line of the 

 pronotum, the rostrum is usually black and highly polished, 

 but is occasionally dull red. 



Belus angustulus. Germ. 



I had previously identified (and tabulated as such) a 

 species from Queensland, New South Wales, and Victoria 

 that appeared (and still appears) to agree well with the 

 description of angustulus, but I have seen no South Australian 

 specimens of it (many of the species of Belus are very widely 

 distributed). But Blackburn identified quite another specie6 

 as angustulus, and as all the specimens before me of this 

 species are from South Australia, the probability is that his 

 is the correct identification. This species (although narrower) 

 has elytra produced much as on phoenicopterus, and each 

 metasternal episternum with a narrow glabrous space at the side 

 (sometimes quite concealed by the' eltyra) ; on the specimens I 

 had identified as angustulus (and which I now consider may 

 represent a variety of inconstans) the elytra are much less 

 acutely produced (somewhat as on angulneus and scalaris) and 

 each metasternal episternum has a conspicuous rounded 

 glabrous spot. 



Belus scalaris, Germ. 



This species varies considerably in size (11-17 mm.), and 

 although the front femora are usually edentate, they are 

 occasionally very feebly dentate. Orroroo. 



Belus cristatus, Lea. 



This species occurs in Western Australia (Cue) as well 

 as in South Australia; in my table ( 3 °) of the genus the species 

 was distinguished from varipilis by the antennae, but the 

 character then relied upon was a sexual one. On the male 

 the basal joint of the antennae is slightly longer than the 

 third, but distinctly shorter than the second and third com- 

 bined, the rostrum is shorter (although still rather long), 

 stouter, and with coarser punctures; on the female the first 

 joint is distinctly longer than the second and third combined. 

 The species, however, differs considerably from varipilis in the 

 clothing, and of the elytral carinae on that species the longer 

 one on each elytron is continued almost to the base, 

 obliquely diverging towards it (much as on the typical form 

 of seniipunctatus), but on cristatus it ends about half-way to 

 the base (being much as noted on the variety paver us of 

 *e mipunctatus ) . Ooldea.
