 der emarginate. Second tarsal joint of all legs except anal pair armed. 

 Anal pair of legs rather long, stout; spines large; superior-interior 

 margin with 3 or 4, which are arranged in two series; 1 within; 2 on 

 the inferior-interior surface; 5-7 beneath and arranged in two or three 

 series; apical process trifid; tibia? and tarsi pilose, the latter more 

 densely; tarsi of penultimate pair also pilose; anal pleurae with its pos- 

 terior margin concave, pilose; apex rather short, with 4 spines; a mar- 

 ginal spine. Length, 100""". 



One specimen without any locality, but as all others unlabeled in the 

 collection seem to be from Surinam, I suppose this specimen is from 

 the same place.
