MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 519 



Female, eighth tergite with four processes, the middle pair longer 

 and more slender. Length, 1 to 1^^ mm. 



Type locality. — Venezuela. Of nitidulv.s, Puerto Rico; of strigosus, 

 Guatemala. 



Types. — Presumably in the Senckenburg Museum, Frankfurt-am- 

 Main. Of nifidulus, either in the Hope Museum, Oxford, or the 

 Zoologische Museum, Berlin ; of sti'igosus, in the British Museum. 



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



Cuba: Cayamas (Schwarz, in U.S.N.M.), Soledad (Darlington, in M.C.Z. and 



U.S.N.M.). 

 Jamaica: Spanisli Town (Blackwelder station 377). 

 Puerto Bico: (Ericbson, 1839b, as nitidulus). 

 South America: Venezuela (Scriba, 1855). 

 Central America: Mexico, Guatemala (Sharp, 1883, as strigosus), Mexico 



(Fenyes, in U.S.N.M.), Panama (Schwarz, in U.S.N.M.). 



Specimens examined. — I have seen one specimen from the West 

 Indies in the British Museum, four from the Museum of Comparative 

 Zoology, one in the United States National Museum, and two col- 

 lected by me during 1935-37. Four examples from Central America 

 were found in the United States National Museum, and the type of 

 strigosus was examined in the British Museum. 



Remarks. — This species may be distinguished by its testaceous head 

 and pronotum. Central American examples which I compared with 

 the type of strigosus are indistinguishable from my West Indian 

 specimens. The above description was drawn from my Jamaican 

 examples. 



My specimens were caught flying at dusk.
