comprise 2 genera and 17 species, of which 8 species are here descril 

 as new (tables 1, 2). The distribution of those in the Western He 

 sphere is shown on maps (figs. 1,2). 



In the first part of this paper, the Uterature concerning the histd 

 biology, immature stages, sponge hosts, and enemies of the Sisyri 

 is brought together, in conjunction with some original observatici 

 The second part deals with the taxonomy of the family, with a j 

 to the genera of the world, and a revision of the species of Sisyriie 

 in the Western Hemisphere. A discussion of the wing venation 

 terminology used in this paper is included in the section on 

 morphology (p. 450). 



Previous taxonomic treatments of the family include monogra 

 by Navas (1935) (reviewed by Lestage, 1935), and Kriiger (1923; 

 the world fauna, and a revision of the Nearctic Sisyridae by Carpeier 

 (1940). An extensive treatment of the British species has been giiii 

 by Killington (1936, 1937).
