MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 259 



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

 52406, collected by E. A. Schwarz on January 5 of 1902, 1903, or 

 1904. 



Records. — The following are the records known to me : 



Cuba: (U.S.N.M.), Cayamas (Schwarz, in U.S.N.M.), Baragua (Christenson, In 



U.S.N.M.), Soledad (Darlington, in M.C.Z. and U.S.N.M.). 

 Hispaniola: Haiti, Port-au-Prince (Audant, in U.S.N.M.). 

 Puerto Rico: (U.S.N.M.), Ponce (Dozier, in U.S.N.M.). 

 St. Croix: (Blackwelder stations 333, 341). 



Specimens examined. — Beside the types I have examined four ex- 

 amples in the United States National Museum, two that were lent 

 from the collection of the Service Technique in Haiti, two from the 

 Museum of Comparative Zoology, and two collected by me in 1935-37. 



Remarks. — This species is rather similar to connexum but differs in 

 the punctation and sculpture of the head, pronotum, and elytra, 

 in the emargination of the base of the head, and in the shape of the 

 labral denticles. It belongs in the subgenus Stilomedon s. str. 



The types were taken "on palmetto"; one other specimen from 

 Cuba was found "in soil of sugarcane fields"; one specimen from 

 Puerto Rico and one from Cuba were found in trash on banana boats 

 at Philadelphia; my specimens were caught flying at dusk.
