The specimen on which Latreille founded this genus was probably 

 the first spider brought from Australia to Europe. 



The genus has not so far been recorded outside the continent of 

 Australia. 



The males are generally smaller than the females, and often of 

 much more brilliant colouring about the head and falces. 



Eleven species have been described, in every case from either the 

 male only or female only. The evidence connecting species of 

 opposite sex either by locality or similarity of some featiu'e is 

 rather slight, but I think they can be reduced to eight at most. 



Synopsis of Species. 



1. Eyes all small and of about the same size. 

 Bodies whole-coloured black-brown (in fe- 

 males at least) 2. 



Eyes of clearly very unequal size 3.
