process is wider, more blade-like, than in E. liicens. The terminal process is bifid at the 

 end, the inner of the two branches stronger than the outer and either a little longer 

 than it or of the same length ; the inner branch may have on its inner side a small blunt 

 projection or tooth. The end of the lateral process is strongly curved but more widely

so than that of E. lucens ; it carries on the curve a strong tooth which points in the 

 same direction as the end of the process. In the axil of that tooth on the hinder side 

 there is always a tiny projection. 



Over 1800 specimens, apart from larval forms, of E. valleiitini have been measured. 

 The largest male was 25 mm. long, the largest female 28 mm., but the vast majority of 

 the specimens were less than 24 mm. in length. One male so small as 13 mm. and 

 several females of 15 mm. were seen carrying spermatophores, i.e. were sexually mature 

 at those lengths, but the usual size for sexually mature individuals is greater.
