Stenus Gayndahexsis, Macl. Specimens compared and agree- 

 ing with the types of this species agree exactly with the descrip-

 Richmond, Clarence and Hawkesbury Rivers and also from 

 Sydney.

 content to leave it. 



Phycosecis litoralis, Pasc. — I have specimens compared with 

 the types of this species and others given to me by Mr. Masters 

 (from whom Mr. Pascoe received the type specimens). I mention 

 this because the species is anything but well described. Pascoe 

 says " beneath the scales appear to be massed together in pro- 

 fusion." In all the specimens I have examined the scales on the 

 vinder surface and legs are somewhat setose in character and are 

 far less dense than on the upper surface. In living (and well-
