MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 435 



eighth sternite with a feeble triangular emargination three times as 

 wide as deep. Female^ eighth sternite rounded. Length, 6 to 7i/2 i^ini. 



Type locality. — Antigua, near summit of Boggy Peak, parish of St. 

 Mary, elevation 1,300 feet. 



Types. — Holotype, male, and five paratypes, U.S.N.M. No. 52461, 

 collected by Dr. H. E. Box on May 30, 1937. One paratype has 

 been deposited in the British Museum and one in Dr. Cameron's 

 collection. 



Records. — The following is the only record known to me : 



Antigua: (Box, as Blackwelder station 444Q). 



Specimens examined. — I have seen only the nine types. 



Remarks. — This species is very distinct by its coloring, and it is of 

 such uniform color throughout these nine examples that I cannot 

 ascribe it to immaturity. 



The types were collected "from inside of scarlet bracts of a large 

 unknown Heliconia sp. (one of the rarest plants of Antigua) in dense 

 mesophytic woodlands."
