Hab. — New South Wales: Jindabyne(H. J. Carter). 



This species was among the Amycteridce brought back from 

 Mt. Kosciusko, by H. J. Carter. It belongs to the P.-impressa- 

 group, but may be distinguished from that and all other members 

 of the group by the widely separated abdominal fascicles. The 

 black colour of the derm, not obscured by scales, and the shiny 

 granules give it a very characteristic appearance.
