The pes II shows a similar difference as that of E. curti- cauda, with fairly well developed articulation between Ri I and II and comparatively short Se Re II. The pes III—IV are like those of the females, but the inner margin of the second basipodite in the fourth pair of legs is completely smooth. The fifth pair of legs (text-figs 33 b and e—g) shows most similarity to that of E. cnrticauda; the right and the left legs are of almost equal length; the Ri dext., which extends almost to the end of Re IinjII, is terminally inflated, and outwards has two rounded processes in the middle; the Re III is.

The left leg has a long and slender Ri, which extends to the end of Re I and terminally is rounded and slightly convex in its whole length; the Re I is fairly long and slender, somewhat concave inside and here possessing a few protuberances; the Re II is somewhat shorter, with a basal rounded process and 2 distal ones, of which the one is short and conical, while the other is about one third as long as the segment, and gradua
