which has evidently been introduced into Australia. Chaudoir 

 recorded L. complanatus from Australia in 1874;* and, according 

 to Bedel, P. australis Blkb. = Z. complanatus. '\

X Bedel, in his Catalogue Raisonni^ des Col^opteres du Nord de I'Afrique, 

 p.216(1902) has the following note — " he nom d' A gowun Bon., est anterieur 

 a celui de Platynus Bon., adopte dans la plupart des ouvrages r^cents. " 

 Probably this contention is strictly correct; though I am not prepared to 

 discard the name Platynus without further evidence.
