ridges setigerous, not definitely granulate; interstices 

 with small tubercles, their apices pointing backwards, suture 

 with only a few elongate granules at base, second with four 

 or five separate tubercles not reaching base nor extending down 

 declivity, third with a more or less continuous row of thirteen 

 from base extending half -way down declivity, the basal tubercles 

 somewhat elongate, the apical ones more subconical, fourth 

 with two or three in middle, fifth with a few at humeral angle 

 rapidly diminishing till only traceable by a row of setae, 

 sixth with a continuous row of twelve more rounded tubercles; 

 sides with rows of round rather flattened tubercles. Beneath 

 convex. Intermediate tibiae with feeble indications of a sub- 

 apical notch. 



Dim. — 9, 13x6 mm. 



Iiab. — Victoria: Nelson (Rev. T. Blackburn). 



Contrary to my usual custom, I have selected a female as 

 the type of this species, partly because the chief specific dis- 

 tinction lies in the mucronate elytra of this sex, partly because 

 I have seen no male from the same locality as a female. In the 

 Museum collection, however, there is a male from Kingston, 

 a neighbouring town in South Australia, which, I believe, 

 belongs to the same species. It is narrower and more elongate 

 (13'5 x 5 mm.), and has the prothoracic granules less obso- 

 lescent in the centre, the elytral tubercles are more elongate, 

 below there is a golden -brown median hirsute vitta, the 

 anterior femora are ridged beneath and the middle tibiae have' 

 a strong subapical notch, also the elytra are not mucronate. 

 The specimen is greatly abraded, but has setae of a light- 

 yellowish colour ; this, however, appears to be a variable char- 

 acter, as the colour differs in the females also. Apart from the 

 mucronation there is little to distinguish this species from S. 

 germarioT S.parvulus; as, however, I have five females before 

 me, all exhibiting the same mucronation, I can only regard 

 this as constant and of specific value. A female from the Howitt 

 collection, National Museum, Melbourne, belongs to this 

 species; it is labelled S. m.ucronatus, Macl. It is, however, 

 smaller (6 lines) than the dimensions given (8 lines) of S. 

 miicronat-us, and the descriptions do not agree; unfortu- 

 nately, the type of S. mucronatus appears to be missing. 



Type in South Australian Museum.
