 diately bordering the tergites. Palp and legs yellowish ; 

 they are slightly darker in the male than in the female, 

 liowever ; malleoli pale and seemingly without any dark 

 rim. 



[i\'o/<?. — There are two more female specimens of Solpuga 

 from Kapiri which resemble those described above very 

 closely in structure, but are very much darker, the dorsal 

 surface of the cheliceraj, head-plate, and abdomen being very 

 deeply infuscate. The palpi and legs also are rather dark 

 brown in these specimens. Probably they are the female of 

 another species.]
