the ventral segments are finely and sparsely punctured, the basal 

 ventral suture almost obliterated in the middle.

I do not observe any structural diiference between this species 



and S. aurugineus, except that this is wider and less parallel in 



form ; its puncturation is so fine and faint as to be scarcely 



visible under a strong lens. The basal margin of the prothorax, 



and lateral margins of it and the elytra, are very narrowly blackish ; 



the suture is more widely so ; in this typical specimen there is a 



black spot on the humeral callus and another between it and the 



suture, and an obscure piceous cloud on the hinder j)art of the 



disc, but in other examples some of these spots are wanting. On 



the underside the pale testaceous colour of the reflexed margin of 



the elytra is in strong contrast with the dark red general surface.

JS. flavifrons, sp. nov. Breviter ovalis ; pubescens ; niger vel 

 piceus ; capite, jDrothorace antice et lateraliter, pedibus 4 

 anticis, tibiis tarsisque posticis, laete flavis ; elytris apicem 

 versus ruf escentibus ; capite prothoraceque subtilissime, elytris 

 minus subtiliter, punctulatis ; sutura ventrali prima in medio 

 obliterata. Long., f 1. ; lat., 4 1. (vix). 

 The yellow area on the prothorax is limited behind by a regular 

 curve with its extremities at the posterior angles and its middle 

 nearly touching the middle of the anterior margin of the seg- 

 ment. The pubescence is moderately dense, and semierect (or at 

 least not flatly depressed), and is of a shining silvery white colour. 

 The puncturation is moderately fine and rather dense, and has an 

 asperate appearance as though there were a tendency to granula- 

 tion on the intervals between the punctures ; it is a little more 

 dense near the sides than elsewhere, and scarcely differs on the 

 upper and under surface except in the middle part of the metas- 

 ternum being almost Isevigate ; it is not unlike that of the 

 European S. cajntatus, Fab., but is a little finer and closer. 



Common, and Avidely distributed in South Australia, occurring 

 as far North as Lakes Torrens and Eyre, also near Adelaide, in 

 the West, &c. 



In company with the above, and equally commonly, I find 

 specimens which I conjecture to be the other sex (probably
