 have a position as distant from the cell as in ordinary specimens of P. belesis. 



We know this form from Mexico : Atoyac and Guerrero, Guatemala, Honduras, 

 and Nicaragua.

While in P. branchus the form with white patch on the forewing is the common 

 one, in P. belesis the white-spotted form is the rarer one.
