reaching tip of tibial claw. In Hirst’s type, as he states, there are two strong 
external spines on the palpal tibia, but only one in all my specimens (ef. fig. 2 B 
and ©). Smaller dorsal setae pointed, 18-291 long, and with short setules; 
longer setae to 220 in length, many of which appear nude but in reality have 
rows of short. adpressed setules as in fig. 2 E; between these extremes are some 
setae of intermediate length, ca. 108, on which there are distinct setules. 
Loc. Hirst’s type specimen, in the 5. Aust. Mus. was from Mt. Gambier, 
8, Aust. I have additional material from South Australia: Flinders Chase, 
Kangaroo Is., Dee., 1934; Victoria: Sassafras 1931, Olinda 1940.
