Length of the lid (front to back) 10J mm. 
Thickness of the lid 1 mm. 
Breadth of hinge 8 mm. 
Galeosoma pilosum Hewitt. 
Locality : May vide, Wonderboompoort, Pretoria College, Koedoespoort, 
Garstfontein, and Lyttelton Junction. 
Also 
Galeosoma hirsutum Hewitt. 
Localities : Roodeplaat, Zeekoegat, Witfontein (near Pretoria North), and 
Rosslyn. 
Nests of these two species are identical, being readily distinguishable 
from those of G. robertsi by the entrance being raised well above the 
surrounding level of the ground, often as much as half an inch, and 
decorated with a mass of bits of grass, particularly on the lid, which is 
usually concave above and fits on to the rim of the entrance and not into 
it as in Stasimopus ; this decoration is a remarkable disguise, for it gives 
to the projecting portion of the tube an exact resemblance to a worn-off 
tuft of dead grass. Some nests were found at Mayville, which were decor- 
ated with small pebbles instead of grass. Nests of members of this genus 
are usually found on level ground, where there are bare patches interspersed 
with grass tufts and small shrubs. At Mayville there are hundreds of nests 
scattered over a flat, in many places being situated only a yard or two 
from one another in great numbers. The two species, robertsi and pilosum, 
occur here side by side, though the latter seems to be the most plentiful. 
Nests of both species were found with young.
