Specimeiis examined. — I have examined 201 specimens from tlie 

 West Indies in the British Museum (and a large series fi'om the rest 

 of the world), 6 from the Museum of Comparative Zoology, 180 in 

 the American Museum of Natural History, 55 in the United States 

 National Museum, and 873 collected by me in 1935-37. 



Remarks. — This is probably the commonest and most wide-spread 

 staphylinid in the West Indies and will undoubtedly be found on all 

 the islands where cattle or horses are kept. 



I have collected it from dung, manure, excrement, and bat guano, 

 flying at dusk, and on the muddy bank of ponds.

 punctate throughout, punctures joined longitudinally by moderately 

 fine channels; with a definite sulcus behind humerus. Abdomen with 

 fine scaly sculpture. 3Ia7e, eighth sternite with two deep incisures
