irregular galleries with a mottled black and soil-colored lining of 
fecal origin. 
Syntermes dims (Fig. 3 e,f): This species builds low-domed termi- 
taria, the major parts of which are below ground level (often to 
depth of 1.5 m.). The galleries are large and diffuse, often containing 
grass stores and are lined with regurgitated soil in which individual 
pellets are clearly visible. 
Velocitermes paucipilis (Fig. 4 g,h): The mounds are pyramidal, 
very soft, crumbly and are generally built around a grass tussock. 
They often extend several centimeters underground in a series of 
very diffuse galleries which are lined with a discontinuous layer of 
black material of fecal origin. Large amounts of cut plant material 
are found inside the mound.
