Affinities. — The alate form of E. palmerstoni is unknown, but the measure- 

 ments of the queen indicate that it is one of the large species, possibly as closely 

 allied to E. vernoni, n.sp. as any other. From the latter it is distinguished, 

 inter alia, by the pronotum and size of the eyes. From E. triodiae Frogg. it is 

 easily distinguished by its much greater size, darker colour and fewer joints in 

 the antennae. The measurements of Froggatt's species (from a co-type) are as 

 follows :— diameter of eyes .304 x .288, length of head 1.27, width of head 1.08, 

 length of pronotum 0.70, width of pronotum 1.03.
