its posterior edge much more abrupt and obviously con- 
cave, and the one on the hind-wings is rather longer and 
rather narrower, so as to appear distinctly more abrupt. I 
do not observe any difference between Walker’s type and 
my Indian specimens, but it is noticeable that all the 
latter are from high altitudes.
