MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 475 



be 110 reason for not accepting new generic names that were pro- 

 posed for valid species. Accordingly Dejean becomes the author of 

 XanthfiJinm unless and until a previous validation of the name is 

 found. 



The names Typhlodes Sharp and Vulda DuVal have been cited as 

 subgenera of Xantholinu^. The original descriptions of these ap- 

 pear to me to contain characters of sufficient importance to separate 

 them generically. 



I have examined G55 examples of this genus from the West Indies. 

 These I assign to 16 species of which 11 appear to be new. One 

 other species recorded from the West Indies is not recognized in the 

 present collections.
