This is a southern species, and apparently rare. I have never seen it in this State, but 
my young friend H. C. De Rham assured me that he. had obtained it from Rockland county. 
His premature and much regretted decease prevented me from examining the specimen. It 
has since been observed in Massachusetts, by Mr. Samuel Cabot. The female does not 
appear to have been described. Its history is still imperfect.
