Head moderately strongly ridged on either side in front, with 

 a feeble, median, laevigata carina. Rostrum little excavate; ex- 

 ternal ridges thick, slightly convergent to base; median carina 

 prominent; sublateral sulci moderately broad, foveate at base. 

 Prothorax (4-5 x 5*5 mm.) rather widely dilatate, widest in front 

 of middle^ subapical and median impressions moderately distinct; 

 closely set with moderately large, rounded granules, larger along 

 subapical impression and behind middle; sides granulate. Elytra 

 (10 X 6 mm.) moderately and evenly widened posteriorly; base 

 emarginate, humeral angles tuberculiforra, produced anteriorly; 

 disc with seriate punctures shallow but moderately distinct, sub- 

 tended by small but evident, setigerous granules; interstices with 

 large, strong tubercles, somewhat elongate towards base, conical 

 towards apex of elytra ; second interstice with a few about 

 middle; third with a continuous row, about nine in number, from 

 base to half-way dqwn declivity; fourth with one or two; fifth 

 with the humeral tubercle followed by a few, small tubercles, 

 rapidly degenerating into granules; sixth with a regular row of 

 closely set tubercles, about twelve in number, smaller than on 

 other interstices, conical posteriorly and outwardly projecting. 

 Sides with interstices granulate. Beneath, with segments flat. 

 Anterior femora feebly ridged on outer half of undersurface; 

 intermediate tibiae with a strong, subapical emargination; pos- 

 terior tibiae more feebly emarginate; anterior tarsi symmetrical. 



5. More ovate than male, ventral segments convex, inter- 

 mediate tibiae simple. 



Dimensions : ^, 16x6; 9, 16 x 6 mm. 



Hab. — Victoria. Type in Macleay Museum. 



Described from specimens in my own collection. The species 

 varies somewhat in size, but I can detect no other difference 

 between the extremes. The presence of the subapical notch on 

 the intermediate tibiae would ally this species with ^. Germari, 

 from which the larger size and sombre clothing will readily 

 separate it. S. Queenslandicus, which is also closely allied, is a 

 somewhat shorter, more ovate species, with fewer tubercles, and 

 inconspicuous, intrastrial granules.
