The appearance of this beautiful species of Bupestris does not at 

 all coincide with that of the family to which it belongs, its opaque 

 costated elytra, rich fulvous colour and pectinated antennae, giving 

 to it much more the character of an Elater or Lycus. 



The characters upon which the recently established genera of this 

 family have been constructed, are in many cases so slight, that I 

 cannot ascertain to which of them the insect in question belongs ; 

 indeed, I should rather suppose that it will constitute a distinct form 

 in the family. 



The presence of a scutellum places this insect in Solier's second 

 division. From Chalcophora Bupestris and Polycesta it differs in 

 the posteriorly lobed thorax, and hence it must belong to the second 

 subdivision, approaching nearest to Colobogaster, Sphenoptera, and 

 Paecilonota, but differing from all these in various parts of the mouth.
