The material for the present paper was partly collected by 

 myself on a recent expedition to Tasmania and Australia. 

 I am also indel)ted to iJr. Hamlyn-IIarris, of the Queensland 

 Museum, and ]\[r. Lea, of the South-Australian Museum, 

 for the supply of specimens, several of which have proved to 

 be novelties.
