 members of the expedition. There are no new species in this 

 collection but as the districts (Northwestern Argentine and the 

 Bolivian Chaco) investigated by this expedition are only little

Fam. Buthidae. 



Subfam. Centrurinae. 



Titytis trivittatus Kr.epelin var. confliiens Borelll

 Borelli^. Kr.epelin has also distinguished the same variety
