This is also a very rare species. I have two very fine male 

 specimens and one female. One male was graciously offered to 

 me by the Authorities of the Smithsonian Institution when I 

 visited this Magnificent Institution in 1876. It was collected 

 by Doctor Bryant at Inagua. The two other specimens were 

 presented to me by my friend, Mr. Chas. Cory, of Boston. They 

 were collected by Mr. C. L. Maynard at Inagua.
