 West Indies in the British Museum, 4 in the Museum of Compara- 

 tive Zoology, 28 in the American Museum of Natural History, 7 in 

 the United States National Museum, and 198 collected by me in

 Central America. 



Remarks. — The above description was taken principally from a 

 pair from San Juan, P. R, This species is one of the most abundant 

 staphylinids in the West Indies. Besides the specimens enumerated 

 above, which are the only ones yet mounted, I collected several 

 hundred of them in a few minutes on several occasions. 



I have collected this species from dung, manure, excrement, sheep 

 dung, and burro dung.
