SCOLECOBROTUS. 



This genus was originally distinguished from L 'r -acanthus 

 by its twelve- jointed antennae, many of the joints being 

 multi-dentate in the male; by the addition of simplex, how- 

 ever, the late Rev. T. Blackburn reduced the distinction 

 simply to an arithmetical one. 



SCOLECOBROTUS WESTWOODI, Hope. 



A female from the Crawford Collection has a conspicuous 

 obtuse tubercle on each elytron near the base, but not being 

 symmetrical they are probably accidental. The species 

 occurs in Victoria, Tasmania, South and Western Australia. 



SCOLECOBROTUS VARIEGATUS, Blackb. 



Typical specimens of this form are readily distinguished 

 from typical ones of the preceding species, by the more 

 rugoisely sculptured base of elytra, the rugose portion sud- 

 denly becoming clouded with black or dark-brown, and 

 glabrous ; from the black subbasal patches a slight infuscation 

 is usually continued along the sides, almost or quite to the 

 apex. But evidently the late Rev. T. Blackburn considered 

 that these were insufficient distinguishing features, as there 

 are specimens from Eyre Sand Patch and Birchip (obtained 

 long after the description of variegatus was published) of 

 specimens of that form labelled by him as westwoodi, although 

 he does not appear to have published anything to that effect. 

 At any rate, even if only to be considered as a variety, it is 

 one well deserving a name. It occurs in New South Wales, 

 Victoria, and South Australia. 



A male labelled as from the Katherine River (Northern 

 Territory) in Mr. French's collection has the elytral punc- 

 tures about the base quite as coarse as on variegatus, but the 

 elytra are nowhere stained with brown.
