clivity; fourth with three or four about centre; fifth with a small 

 humeral tubercle, followed by a row of others, variable in number 

 and p(xsition, generally obsolete after the shoulder, in type(?) 

 eight in number, nearly reaching declivity; sixth with about ten, 

 small, conical tubercles, more closely placed than in S. long us. 

 Otherwise as in that species. 



9. More ovate than (J; convex beneath, with the median vitta 

 less marked. 



Dimensions : ^J, 19 x 6*5; 9, 20 x 8 mm. 



Hab. — South Australia: Flinders Range, Gawler Ranges — Vic- 

 toria: Birchip, Sea Lake, Murray River. 



Described from a pair in the Macleay Museum, which agree 

 with Macleay's description, and are probably his types. The 

 male, however, has the fifth interstice more tuberculate than in 

 any other specimen I have seen. The size of the tubercles 

 varies; in some specimens they are larger than in -S^. long its, in 

 others they are smaller. The number of tubercles on each inter- 

 stice also varies considerably. 



The specimen standing over the label -S^. mucronatus MacL, in 

 the Macleay Museum, belongs to this species, but does not agree 

 with the description of S. mucronatus.

9. Elongate, elliptical-ovate. Black ; densely clothed with 

 brown squamosity; prothorax indistinctly trivittate; each elytron 

 trivittate, an incomplete vitta along each side of suture at the 

 base, a vitta internal to third interstice, and a broader vitta along 

 each side of disc; sides of prothorax and lower portion of sides 

 of elytra also with lighter clothing; below, densely clothed with 

 light grey, and with a reddish-brown, median vitta. 



Head and rostrum as in S. long us. Prothorax (5 x 6 mm.) sub- 

 angulate, dilatate; subapical impression well marked; moderately 

 closely granulate, granules small, slightly larger about constric- 

 tion, and in the middle near the base, absent or fewer and
