MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 101 



eighth sternite produced at center, ninth more acutely produced. 

 Length, 1 to 1% mm. 



Type locality. — "ISfadera australi," Levada. 



Types. — In Wollaston collection in the British Museum. 



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



Jamaica: Milk River (Blackwelder station 415), Moneague (Blackwelder station 

 375), Trinity ville (BlackNvelder station 428), Santa Cruz (Blackwelder 

 station 421), Spanish Town (Blackwelder station 377), Moutego Bay (Black- 

 welder station 407; A.M.N.H.), Troy (Blackwelder station 409). 



Dominica: (Blackwelder station 252; Weber, in M.C.Z. and U.S.N.M.). 



St. Vincent: (Fauvel, 1902; British Museum). 



Grenada: (Fauvel, 1D02; British Museum). 



Atlantic Islands: Madeira, CANAr.iES, Mauritius (Fauvel, 1902; Wollaston, 

 1854, 1864, 1865). 



Specimens examijied. — I have examined 147 examples from the West 

 Indies in the British Museum, 3 in the American Museum of Natural 

 History, 2 from the Museum of Comparative Zoology, and 41 collected 

 by me in 1935-37. 



Remarks. — This is one of our smallest species. It is very distinct 

 in its carinulate sculpture. It has been regarded as an introduction 

 into various countries in commerce from Madeira, where it was first 

 discovered. On the other hand, there is no evidence that it had not 

 existed for many years in the West Indies before it was discovered 

 there, and it is impossible to stat« the region of its origin. 



I have collected it under seaweed on a coral reef and flying at dusk.

 longitudinal grooves and lateral depressions; shining, with moderate
