The specimens on which the above description is founded were 

 given to me by the late Mr. W. Kershaw, of Melbourne. They seem 

 to represent the form on which Castelnau bestowed the name 

 Feronia plutus. Two specimens {$) sent to me by Mr. C. French, 

 as from Mount Baw Baw, Gippsland, seem to represent Feronia
