20. PARALASTOR INSULARIS Sauss. 
Unlike any other species superficially, the second abdominal 
segment black, with the extreme apex only indistinctly pale. 
Hab. Australia, Swan River; 1 ¢. 
21. PARALASTOR TUBERCULATUS Sauss. (PI. I. fig. 3.) 
A very distinct species, of which I have seen six females, four in 
the British Museum Collection and two in the Oxford Museum. 
This species should be removed from this position and placed 
next to P. odyneroides (no. 67). 
Hab. Tasmania; Adelaide: Victoria (Yrench). In the latter 
locality the abdominal bands are deeper yellow, in one example 
more orange-colourcd. 
22. PARALASTOR EMARGINATUS Sauss. 
Hab. Tasmania, 1 @ in the Oxford Museum; Eaglebawk 
Neck, 5.H. Tasmania, Feb. 12th—March 3rd, 1913,1 9 (Zurner). 
23. PARALASTOR PARCA Sauss. (PI. I. fig. 1.) 
In one or two females the clypeus is quite truncate at the apex, 
and others are intermediate between these and those in which 
it is quite distinctly, though always shallowly, emarginate. 
Hab. Tasmania, Franklin; Mt. Wellington and Eaglehawk 
Neck (Turner); Victoria (French).
