Dumitus jamaicensis. 



Primaries : basal third almost black on costa, shading to gray on inner margin ; 

 this space limited by a dark line not extending below the submedian ; a median 

 whitish space, wider on costa than on submedian, irrorated with darker scales and 

 strine, but not thickly ; below the submedian the inner margin is grayer ; a velvety 

 black discal point ; outer space dull gray ; an outer pale gray row of spots between 

 the veins, and terminal pale gray shadings, especially about and above inner angle ; 

 all the terminal space slightly irrorated with darker strise ; fringe buff, spotted with
