90 MR. H. R. HOGG ON SPIDERS 
The sternum is shield-shaped, straight in front, rounded at the 
rear, where it is nearly as broad as in front, the rear coxe being 
2 of their width apart. 
The legs are long and fine, tapering anteriorly. They are only 
sparsely furnished with short downlying hairs on the femoral 
joints, and short bristly upstanding ones on the other joints. 
There are five or six pectinations on the superior tarsal claws. 
There are three pairs of long spines on the under side of all tibie, 
two pairs underneath the metatarsi and about five shorter at the 
anterior end of same. 
The abdomen is broken in each specimen, but in one of them 
the epigyne is intact; it is roughly similar to, but more elaborated 
than that shown in L. Koch’s drawing of the only species pre- 
viously recorded from Australia.

Two females sent by Mr. Haynes. 
These would seem to differ from P. albessens L. K. in the 
lighter and brighter colouring, in having no row of dark spots on 
the side slopes Toe he cephalothorax, in ‘the ereater length of the 
legs compared with the cephalothorax (4 to 33), and the clypeus 
not so long as the eye-space, and the more defined epigyne.

The cephalothorax is black-brown on the cephalic part, dark 
yellow-brown on the thoracic. On the former and on a marginal 
stripe are downlying white hairs interspersed with orange. The 
side slopes and posterior end are bare; on the clypeus is a fringe 
of coarse orange-coloured hair. 
The mandibles are black-brown with a few brown bristles on 
the basal half. The fangs are dark yellow-brown.
