From these tabulations it appears that 8 percent of the species not 

 restricted to the islands occur also in North America only, 9 percent 

 in Central America only, 21 percent in South America only; 2 per- 

 cent in both North and Central America, 3 percent in both North 

 and South America, 13 percent in both Central and South America, 

 and 15 percent in all three parts of the mainland. Furthermore, 

 combining the above, 27 percent occur in the islands and in North 

 America (at least), 46 percent in the islands and in Central America 

 (at least), and 56 percent in the islands and in South America (at 

 least). Of these same 97 species that occur in the islands and on 

 the mainland, 16 percent occur also in the Eastern Hemisphere. 

 And 2 species in the West Indies occur also in the Eastern Hemi- 

 sphere but not on the American mainland at all. 



Some entomologists have considered Trinidad (and Tobago) to 

 be South American and not related to the West Indies faunally. 

 In support of this the present study includes 54 species that occur 

 in Trinidad alone and 13 species that occur in Trinidad and South 

 America but not in the true West Indies. It should be noted that 

 the staphylinid fauna of Venezuela is only slightly known, and it 

 is likely tliat many more of the Trinidad species Avill be found also 

 on the mainland. The evidence that has led me to include Trinidad
