Locality .—Alice Springs. The single specimen brought back by the Expedi¬ 
tion has become much discoloured by alcohol, the green having changed to a tawny 
l)rown. The species occurs, however, in the mallee scrubs of southern Australia, 
but is always more or less rare. Having been unable to fit it into any of the 
genera characterised in the Keys of Hermann and Brunner, a new genus has been 
formed for the reception of the species, which may possibly be Walker’s Ephippigern 
i/roroia. The italicised parts of the description denote its differences from other 
and especially from the Australian genera Metaballus and Rachidorus, occupying 
a somewhat intermediate position. 
Gryllacrid.e. 
Gpyllacpis stpaminea, Tepper (Trans. Roy. Soc. S.A., 1892, p. 150). One 
female. The specimen is considerably smaller than the type from North-western 
Victoria, and the organs of flight proportionally longer, otherwise it resembles it as 
much as individuals of the same species usually do. If correctly diagnosed, the 
distribution is a very wide one. The male is still unknown to me. Rare.
