MONOGRAPH OF WEST INDL\N STAPHYLINIDAE 443 



Remarl's. — This is a variable species in size, color, and details of 

 sculpture. I was unable to separate the specimens segregated under 

 the above names in the British Museum and Dr. Cameron's collec- 

 tion, and cannot now separate my specimens satisfactorily. It seems 

 iairh' certain that only one species is represented, occurring from 

 Cuba to Grenada, at least. It differs from arduus Sharp of Central 

 America in size, the unimpressed front of the head, and many de- 

 tails of sculpture. 



One example from the Dominican Republic and one from Trinidad 

 differ from the others in the punctation of the pronotum and elytra. 

 They do not fall in the range of variation observed in the large 

 series, but I am unwilling to describe them as new from unique speci- 

 mens. They are now in the Museum of Comparative Zoology. 



I have collected this species from dung and manure, from the 

 muddy banks of ponds, from beneath stones along streams, and 

 flying at dusk.
