Maris capite, prothoracis lateribus et femoribus anticis 

 liete rufis. 

 Much more sparingly punctured than either of the preceding 

 two species. The testaceous spot on each elytron comes near 

 touching both the suture and the lateral margin ; its front edge 

 is separated from the anterior margin by a distance equal to 

 about two-thirds the length of the prothorax, and its hind margin 

 falls a little behind the middle of the elytron. In shape it may 

 be described as a quadrate figure a little wider than long, deeply 

 emarginate posteriorly, and having its antero-external corner cut 

 off or emarginate. The suture between the first and second ven- 

 tral segments is fine but distinct. 



Common near Port Lincoln ; also in the Adelaide district.

 The puncturation, compared with that of *S'. Jlavifrons, simplex, 

 &c., is much smoother and more sparse. It is not unlike that of 

 S. Meyricki, which, however, is a wider insect proportionally. The 

 sculpture of the prosternum at once distinguishes it from nearly 

 all its allies. The sides of the metasternum are closely, and the 

 ventral segments less closely, punctured ; the middle of the former 

 is finely wrinkled transversely. There is a small distinct sixth 

 ventral segment. The first ventral suture is fine, but distinct.

 The elytra are broadly red in the basal third of the lateral 

 margin, and this red mark is prolonged from its hinder end 

 obliquely towards the suture which it approaches (but not very 

 closely) just in front of the middle ; the hinder red spot occupies 

 the apical one-sixth of the elytra. The puncturation of the elytra 

 is stronger than in any of the Scymni described above. The
