Remarks. This species is an inhabitant of Trinidad 

 and Bayamo in Cuba. A single specimen, found at Key 

 Biscayne, Florida, (Smithsonian Coll.) is figured on the 

 plate, magnified to twice its natural size. Whether its 

 introduction was but accidental, or whether it is well 

 established in Florida, remains to be proved.
