are of more equal size and the interlamellar hairs are stouter and slightly hairy. 
Pseudostigmata and pseudostigmatic organs of the same shape as in O. longz- 
pilus but larger. The posterolateral angles are thickened to two strong, semi- 
circular ridges. Between them there is a pair of rounded, button-shaped pro- 
jections. 
Hysterosoma (fig. 65). The anterolateral angles project into a pair of 
strong, triangular teeth which presumably act against the semicircular ridges of 
the propodosoma described above. The cuticle is very finely punctured, the

punctures being arranged in radiating rows in a faintly defined marginal shield. 
There are two longitudinal rows of 6 blunt and stout, slightly hairy, perpendicular 
bristles about half way between the centre and the sides, and 4 pairs of sim- 
ilar marginal hairs in the posterior half. A little behind the anterior bristles 
but further laterally on the marginal shield there is an oblique slit-shaped pore. 
The ventral side is of the typical shape as are also the legs. 
Loc.: Juan Fernandez. The species is very common on Masatierra 
being found in all the 8 localities where dry leaves were gathered.
