This species builds reddish nests up to two meters in height 

 of elongate, more or less column-like shape, in the open dry 

 savannah forests in West Kimberley as showed by Text Figs. 

 59, 60. The cover of the nest is about two inches thick and

consists of härd sandy and earthy substances; the interiör 

 is made of a much softer, darker material of chewed wooden 

 substance, is which the galleries are excavated; the latter are 

 separated from each other only by a thin wall and are very 

 often quite full of small pieces of grass, which are dried up 

 in the more externally situated galleries (for disinfection!) 

 and are then transported to the central and more basalparts' 

 of the nest, where they are chewed to powder and used as 

 food for the young. 



The species is apparently quite distinct from those 

 already described. Perhaps it is allied to E. hastilis Frogg
