and the median joints longer and more slender, the apical 

 ones considerably shorter. From E, pyriforfnisFROGG., to which 

 species it apparently comes nearest, it differs by the very dark, 

 almost black liead with an indistinct median lighter line, 

 by the less rounded sides which are more tapering towards 

 the slightly broader and stouter snout, by the more 

 slender, longer and darker coloured antennae, etc. In general 

 appearance it is very much like the New Guinea species E. 

 princeps Desn., specimens of which have been kindly placed 

 at my disposal by Dr. Nils Holmgren; it has the same 

 darkly coloured head with a lighter median line, but on

closer examination, it proves to be quite another species, 

 having 14-jointed antennae with very long and slender joints 

 (in E. princeps DESi^f. 13- jointeå antenna? with quite different 

 joints). 



T have found this species in the very characteristic large 

 mushroom-shaped nests of red clay or sand as a cover and 

 the more brittle darkly coloured, internal galleries which are so 

 typical of the Kimberley landscape (see Text Fig. 13) in North- 

 west Australia. I observed exactly the same type of nest in 

 the open savannah country near Evelyne and Cedar Creek in 

 North Queensland; they were inhabited by the same dark-
