This species is at once differentiated from all the described 

 Australian Bembidiides by its multistriate elytra, which have the 

 ordinary interstices from the 1st to the 8th inclusive divided into 

 two narrow ridges. The form of the lateral interstice — with the 

 position of its setigerous punctures, — and the junction of the 

 lateral channel with the 10th stria (representing what would be 

 normally the 5th interstice) indicate a relationship with Tachys 

 buprestioi'Ies, SI. Mr. F. P. Dodd sent me this strange species as 

 taken by him at Ross River, 5i miles from Townsville.
