740 FP. MUIR AND J. C. KERSHAW. 
All these specimens were taken in the vicinity of Péroe 
(Western Ceram) living in old logs and stumps of trees in a 
certain stage of decay; im one case just under the bark, but 
in all the others some distance below the surface, working 
their way in along cracks and runs made by insects. In 
captivity their favourite food is the pupz of wood-boring 
beetles, which they bite open and suck out the contents. 
This species, the first taken in the Moluccas, appears by 
the female characters to differ from all others and to form a 
distinct group. In the size of the eggs and its mode of 
development and birth it approaches the neotropical group 
but 1s quite distinct in all other characters, such as number 
of legs, position of vagina, shape of papillae and number of 
pads on the legs. In these latter characters it comes nearer 
to the South African and Australian species, but the bilobate 
ovarian chamber with the single duct leading from it places 
it quite apart. It will be of interest to see if Papuan species, 
when found, will agree with it.
