Eh/tra loug, broader and more than twice longer than the thorax, widest near the 



middle, deep black, very smooth and shining, sides slightly margined, epipleural 



fold yellow, apex rather acuminated. 

 Li'fis rather long, bright yellow. 

 Under parts piceous, mouth, prothorax, and epipleura yellow, uietasternum and first 



ventral segment very smooth and shining. 

 Differs from all other species in its large size, ovate form, impunctate surface, very 



remarkable colour, and the short and greatly incrassated club of the antennse. 

 Habitat, South America. Found in Chili. 



Some specimens, probably females, are smaller and much jjaler in colour. 



In the shape of some parts of its antennffi, and of the lobe of the maxilla, this 

 species differs very much from the type of Cori/liqiJiodes, but I do not think that 

 these points are by themselves of sufficient importance to constitute a distinct genus.
