and having a white band across liind wings ; expanse of wings 

 3 inches 5 lines.

This variety is most interesting as it is the lightest form of this 

 very variable species which is yet known ; the female of the form 

 P. Laslnassa has never been figui-ed, therefore it is important 

 that this insect, which better exhibits the extent of modification 

 to which the species is subject, should be made known.
