For the opportunity of figuring this species from the 

 Ciconia nigra, I have to acknowledge the kind assistance of 

 Professor Burmeister of Halle, who, with a liberality rising 

 superior to the dictates of self-interest, and which only those 

 who love science for its own sake will put in practice, for- 

 warded me specimens of several species, which I could not 

 obtain elsewhere. When I state that Dr. Burmeister is 

 himself engaged upon a work on Parasitic Insects, with 

 figures of the species, his disinterested conduct requires no 

 comment.
