 This is an inconspicuous species bearing much superficial re- 

 semblance to /'./uK-ea'a and syrdila from both of which it differs 

 by its much smaller size and the considerably finer puucturation

 tonetniis and opa-^ior but differs from them inter alia by the very 

 distinctly though narrowly explanate sides of its pi'othox'ax.
