466 ON CARABID.E FROM WEST AUSTRALIA, 



Jlavocinctus and L. ohscurus, BIkb., by having the prothorax less 

 transverse; apparently it is closely allied to L. lindi, Blkb., but 

 has the margin of the elytra (including the posterior half of the 

 ninth interstice, and the eighth near the apex) lightly coloured. 

 It is characteristic of Lecanomerus to have three punctures on the 

 ninth interstice placed a little before those near the apex.
