12 LE CONTE.— LONGICORN COLEOPTERA 



I am by no means sni*e that this genus is in reality distinct from Ehuria; in a 

 large Mexican species of the last genus, with small elytral spot, the joints of the 

 antennae seem inclined to become compressed, and it is quite possible that in other 

 species they may even become sulcate as in Cerasphorus.
