368 ON THE AUSTRALIAN BEMBIDIIDES, 



Tachys flinderbi, Blackburn. 



T. Jlindersi, Blkb. = Tachys [Bemhidium) ruhicundus, Macl.,

Habits : — Found under logs and stones in very damp situations. 



Hah. : Queensland — 'Gayndah (Masters); N.S. Wales — Tam-

 Upper Ovens River (Blackburn), Lilydale (Sloane) ; Central 

 Australia (Spencer); West Australia — Darling Ranges (Lea).
