Key to Species of Hippobosca 
I have studied specimens of the seven valid species sepa- 
rated by the subjoined key, which I have attempted to base 
mainly upon reliable structural characters. I have found 
that the coloration, although often helpful, is rather varia- 
ble in certain species, and I do not regard it as of specific 
value when no differences in structure can be discovered. 
Hippobosca fulva Austen appears to be distinct from the 
other seven. I have not seen it, and the characters given 
in the description do not allow of its being included in my 
key.
