slender and very curved with a sharp horny tip. The exposed por- 

 tions of the upper surface, the merus and practically all of the upper 

 surfaces of the carpus, propodus and dactyl are paved with a mosaic 

 of flattened or slightly elevated tubercles ; on their upper lateral mar- 

 gin these tubercles become serrate, spinose tubercles, as they do also on 

 the dactyl. On the meral and carpal joints these spinose tubercles are 

 concealed beneath a dense brush of setae. There are two thick tufts 

 of bristles on the horny curved tips.
