Montserrat: (Blackwelder station 269). 



Guadeloupe: Basse Terre (Blackwelder station 75; A.M.N.H.). 



Dominica: (Blackwelder station 242). 



Grenada: (British Museum). 



Specimens exaniined. — I have examined 2 examples in the British 

 Museum, 3 in the American Museum of Natural History, and 21 

 collected by me in 1935-37. 



Remarks. — The specimens in the British Museum were placed under 

 A. gracilis Sharp from Central America. I was unable in a hurried 

 examination to separate these or my specimens from the type of 

 gracilis. However, A. iiMiilatvs was described much earlier from St. 

 John (Virgin Islands of the United States), and I cannot separate 

 it from the specimens under consideration. I therefore conclude 

 that the West Indian examples represent the ustuJatus of Erichson 

 and that the gracilis Shar]5 should not be in our lists unless it is 

 a synonym of lUifAilafus., which I am unable to prove. 



I have collected this species from under cow dung, from under 

 seaweed on the beach, and flying at dusk.
