astonishingly easy to make mistakes in their determination.” This 
is still true, partly because no key to the species exists. It was beyond 
the intent of this study to prepare one. 
In the following list, references to Bouvier (1905, 1907) and 
Clark (1913a, 1913b, 1915a) are not individually given because 
they apply to almost all species. Also, dates and literature citations 
to descriptions of Bouvier (1905, 1907) and earlier are not given, 
because they may be found in these works. The word “seen” indi- 
cates specimens from the Museum of Comparative Zoology and the 
Institute of Jamaica on which some data are based. All new records 
reported here are based on specimens of the Museum of Comparative 
Zoology. A history of synonymy of each species is not given because 
the intention of the list is only to report presently accepted species 
and their documented localities.
