The species are, for the most part, but little known. Over forty of the ninety- 

 five recorded species are known only from the types, which are widely scattered. 

 Ten or twelve of the types are in Vienna, two are in Berlin, eleven or twelve in 

 Paris, eleven in London, one in Torino, Italy, two possibly in Munich, one in the 

 University of Leipzig, two in Copenhagen, three presumably in Santiago, Chile, 

 three in Buenos Aires, five in Rio de Janeiro, two in Cordoba, Argentina, one in the 

 Field Museum, two in the Philadelphia Academy of Sciences, eight in the Museum 

 of Comparative Zoology at Harvard, eight in Indiana University, twenty-four in 

 the Carnegie Museum, one in Princeton University. The Carnegie Museum pos- 

 sesses forty-six species, Indiana University is next in line with thirty-two species, 

 and the Museum of Comparative Zoology comes third with twenty species.
