mme colour across the anterior marpjin o£ the elytra, often in- 

 terrupted by a blue scutellum. The carmine (rather than 

 coppery) tint of the iridescence, which the whole upper sur- 

 face displays in certain lights, the strongly rounded lateral 

 margins of the thorax, perfectly straight anterior margins of 

 the elytra, and the strong elevation behind of the second elytral 

 interstice (no other interstice being distinctly elevated, the 

 fourth is feebly so in some specimens) are all characteristic 

 features. It should also be noted that the punctures on the 

 disc of the thorax are not round but somewhat elongated trans- 

 versely, although some specimens have the disc of the thorax 

 more roughly punctured, and in these the individual punctures 

 hardly display this character distinctly, but there is a tendency 

 to transverse wrinkling ; probably this difference in the thor- 

 iicic puncturation is sexual. 



I have seen many specimens from Port Lincoln and the 

 Adelaide district.

 The markings of this species render it incapable of confusion 

 wdth any other. I think its affinity is with iLT. rotundicoUis 

 mihi, and 21. infricata, mihi, especially the latter, from which, 

 however, it differs (independently of the totally different 

 markings) in the slighter curve of the sides of the prothorax, 

 the much feebler and more sparing puncturation of the under- 

 side (especially the prosternum) on the median line, &c. The 

 cupreous clouding of the thorax seems to vary. In one speci- 

 men that I have before me it consists of a faint longitudinal 

 spot on either side, in another it suffuses the whole surface 

 except on a portion of the median line. The prothoracic
