I believe I am right in separating this from galeata Halliday, as it 

 does not agree altogether with Becker's description of that species 

 nor with those specimens of galeata I met with in Britain, but the 

 specimen is not in good condition, and it is impossible to do more 

 than point out the characters in which it does not agree with galeata.
