Genus P a c ii v o a s t e r. 



This genus is represented m my collection by two Tas- 

 manian specimens, both taken in the centre of Hobart. 



Neoexaireta spinigera, WaU-. 



This species has been taken several times by Mr. F. 

 M. Littler and Mr. C. Cole at Launceston, and so must be 

 added to the Tasmanian list.

Gen. P E L E c o t: h y n c h u s. 



Two new species, and one variety of this interesting 

 and rare genus are here ?dded. P. eristaloides, su/mj). 

 iiHuitaiiiix. must now lauk as a distinct species, and not a 

 local Mountain variety, so a fuller description is given to 

 augment the previous scanty remarks. It seems probable 

 that the genus is chietly marsh frequenting, so large tracks 

 of marsh areas, both in Australia and Tasmania, are likely 

 to produce many new species. 



The following key will easily separate all the known 

 Tasmanian species of this genus: — 



1. Abdomen black, shining. fiisrtuiKjer, Walk. 

 Abdomen banded. 2 



2. Bands en abdomen interrupted in the centre. 4
