Obs. This insect presents perhaps one of the most curious and novel forms of the whole 

 collection. Its brilliancy and variety of colour, its beauty of sculpture and its similarity at first 

 siffht to the Linnean genus Buprestis, altogether render it a most extraordinary insect to be 

 placed among the Necrophaga : yet it cannot be doubted that the true place of this curious 

 insect is in this stirps. The only other insects to which it bears any similarity are the Buprestida;, 

 and it will prove perhaps, by reason of the strong relation of analogy which it bears to this groupe, 

 most useful in shewing their place in their own tribe. That it does not, however, belong to the 

 Buprestidce clearly appears from its horizontal head, the lateral insertion of its clavate antenna?, 

 the structure of the lower surface of its body, and above all from its organs of manducation. In 

 all these particulars, on the other hand, it agrees with the general characters of the Necrophaga, 

 some of which, such as the genus Languria, display a similar brilliancy of colour, and a form even 

 more longitudinal. Near to this genus, therefore, and to Dacne I conceive HelotaVigorsii to come, 

 since it also agrees with the latter in the form of its antennae and structure of mouth. The 

 feet nevertheless are constructed differently from those of both these genera, for although our 

 insect is with still greater difficulty detected to be pentamerous, the minute evanescent joint
