73. DIORUS, n. g. 



Head with the antennae rather short, the joints on the inside 

 somewhat dilated and cup-shaped, each being received into the 

 one before it, the third joint hardly longer than the others ; face 

 very short, eyes very large. Thorax as wide as long, the middle 

 elevated into two large transverse tubercles ; sides nearly par- 

 allel. Elytra wider at the base than the thorax, tip produced 

 into a spine. 



This genus is allied to Criodion, and has at first sight a con- 

 siderable resemblance to some of the species of the Australian 

 genus Phoracantha.
