 long, broad, flat and curved over at apex, ending in a rather long 

 apical segment, surface of clasper minutely spinose ; harpes long, 

 notched on their basal half and terminating in a broad fish-hook- 

 like process ; harpogones thick, short-curved, densely chitinous.

 basal lobes.)

Habitat.— Brazil (Dr. Lutz). 



Observations. — Described from a single £ given me by

 brown hue, no special adornment, spinose legs and uniserrate 

 hind ungues.
