Described from one $ (?) in my collection from Key Island. 



N.B. — I do not know on whose authority the above specimen 

 is identified, but it is the only one I have seen purporting to be 

 this species. It is to be noted that in Doleschall's figure of his 

 ventrimacula the anal cell is closed, not open as in mine and as 

 is shown in Macquart's plate of his audouini, and that the face of 

 mine is distinctly reddish, which is not mentioned in any of the 

 synonymic descriptions.
