186 NOTES ON AUSTRALIAN COLEOPTERA, 



that genus the palpi are of very extraordinary structure and the 

 basal joint of the hinder tarsi is very widely triangular. The 

 general appearance of the insect on which I found this genus is 

 much like that of Novapus, with which genus, however, it does 

 not appear to be closely connected, differing from it inte7' alia 

 multa by its very much shorter and thicker hind tibiae.
